Abstract
Description
- The following relates to a reaming tool and, more specifically, relates to a modular reaming system for a femoral revision procedure.
- The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
- Prosthetic joints can reduce pain due to arthritis, deterioration, deformation, and the like. Prosthetic hip joints often include a femoral component that is fixed to the patient's femur and an acetabular cup that is fixed within the patient's pelvis. More specifically, the femoral component can include a stem that extends into the patient's resected femur and a rounded head that is received within the acetabular cup. The head can articulate within the cup so as to moveably couple the femoral component within the acetabular cup.
- Typically, a superior portion of the femur is partially reamed to create a reamed opening that receives the femoral component of the prosthetic hip joint. In some cases, multiple reamers of varying widths are used at different portions of the femur such that the resultant reamed opening varies in width and to match the geometry of the femoral component of the prosthetic joint. As such, the reaming process ensures that the femoral component properly fits within and fixes to the femur.
- Although reaming systems have been adequate for their intended purposes, these systems can be improved. For instance, reaming processes can be time consuming and inconvenient, especially if multiple reamers are needed for reaming different portions of the femur.
- A modular reaming system is disclosed for reaming a plurality of pockets in an anatomical feature. The system extends along a longitudinal axis. The system also includes a first reamer in a first position on the longitudinal axis, and the first reamer reams a first pocket in the anatomical feature. The system further includes a second reamer that is removably coupled to the first reamer in a second position on the longitudinal axis. The second reamer reams a second pocket in the anatomical feature. The second reamer is keyed against rotation relative to the first reamer to ream the first and second pockets substantially simultaneously.
- In another aspect, a modular reaming system is disclosed that includes a first drive coupler, a second drive coupler, and a first reamer driven in rotation by the first drive coupler. The system also includes a second reamer driven in rotation by the second drive coupler or driven in rotation by the first drive coupler.
- In addition, a method of reaming a femur is disclosed that includes removably coupling a proximal reamer to a shaft fixed to a distal reamer. The method further includes retaining the proximal reamer against rotation relative to the distal reamer. Also, the method includes rotating the shaft in a single direction to substantially simultaneously ream a proximal pocket in the femur with the proximal reamer and a distal pocket in the femur with the distal reamer.
- Moreover, a reaming system is disclosed that reams a femur for implantation of a femoral component of a prosthetic joint. The reaming system includes a distal member extending along a longitudinal axis. The distal member includes a first shaft, a distal reamer, and a first drive coupler. The distal reamer and the first drive coupler are fixed to opposite ends of the first shaft. The distal reamer reams a distal pocket in the femur, and the first shaft includes a first flat surface. The system further includes a proximal member including a second shaft, a proximal reamer, and a second drive coupler. The proximal reamer and the second drive coupler are fixed to opposite ends of the second shaft. The proximal reamer reams a proximal pocket in the femur, and the second shaft includes a second flat surface. The proximal member removably receives the first drive coupler and the first shaft to removably couple the proximal and distal members. The distal reamer extends out of the proximal member, and the first flat surface mates with the second flat surface to couple the distal member and the proximal member against rotation relative to each other to ream the first and second pockets substantially simultaneously. Furthermore, the system includes a retention member that limits movement of the proximal member axially relative to the distal member.
- In still another aspect, a modular reaming system for reaming a plurality of pockets in an anatomical feature is disclosed. The modular reaming system includes a longitudinal axis and a first reamer in a first position on the longitudinal axis. The first reamer reams a first pocket in the anatomical feature. The system further includes a second reamer that is removably coupled to the first reamer in a second position on the longitudinal axis. The second reamer reams a second pocket in the anatomical feature. Moreover, the system includes a means for coupling the second reamer against rotation relative to the first reamer to ream the first and second pockets substantially simultaneously.
- Still further, a modular reaming system for reaming a plurality of pockets in an anatomical feature is disclosed. The modular reaming system includes a longitudinal axis and a first member with a first reamer that reams a first pocket in the anatomical feature. The first member includes a first surface. The system further includes a second member with a second reamer that reams a second pocket in the anatomical feature. The second reamer is removably coupled to the first member. The second member includes a second surface that is complementary to the first surface so that rotation of one of the first and second members about the longitudinal axis causes rotation of the other of the first and second members for substantially simultaneous formation of the first and second pockets.

It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features. Moreover, while the reaming system described herein is described in relation to reaming an intramedullary (IM) canal of a femur, the reaming system can be used in any other area of a patient as well.
- Referring initially to
FIGS. 1 and 2 , a reamingsystem 10 is illustrated according to various exemplary embodiments of the present disclosure. The reamingsystem 10 can include ashaft 12. Theshaft 12 can be elongate and can have a substantially straight longitudinal axis X. Furthermore, theshaft 12 can have a roundedportion 14 and aflat surface 16 as shown in the sectional view ofFIG. 3 . More specifically, theshaft 12 can be partially circular in cross section due to the roundedportion 14, and theflat surface 16 can be included on a chord of the cross section. The roundedportion 14 and theflat surface 16 can both extend along the majority of theshaft 12 in a direction substantially parallel to the longitudinal axis X. Also, theflat surface 16 can be located on only a portion of theshaft 12. - The
system 10 can also include afirst reamer 18. Thefirst reamer 18 can be disposed at a first (distal) end 20 of theshaft 12. Thefirst reamer 18 can be substantially cylindrical with a pointed end and can be fluted so as to perform reaming operations, for instance, in bone or other suitable materials. Thefirst reamer 18 can be fluted in either the left-hand or right-hand direction about the axis X. In some embodiments, thefirst reamer 18 is integrally coupled to theshaft 12 so as to be monolithic; however, thefirst reamer 18 can be removably coupled to theshaft 12 in some embodiments. Theshaft 12 can also include ashoulder 22 adjacent thefirst reamer 18. As shown, theshoulder 22 can be generally wider than surrounding portions of theshaft 12. - The
shaft 12 can also include afirst drive coupler 24. Thefirst drive coupler 24 can be coupled to theshaft 12 at a second (proximal) end 26 thereof. Thedrive coupler 24 can include any suitable features for removably coupling theshaft 12 to a driving device 28 (FIG. 5 ). The drivingdevice 28 can be a motor powered by electricity, pneumatics, hydraulics, etc. The drivingdevice 28 can also be powered by manual input. As such, the drivingdevice 28 can drivingly rotate theshaft 12 about the axis X. - As shown in
FIGS. 1 and 2 , thesystem 10 can further include one or moremodular spacers 30. Eachspacer 30 can be tubular in shape and can have a width (i.e., diameter) substantially equal to that of thefirst reamer 18. Thespacer 30 can include grooves so that, during reaming operation, materials removed by thefirst reamer 18 can move along the axis X and pass thespacer 30. Thespacer 30 can also include anaperture 32, such as a through-hole that extends therethrough. In the embodiment shown, theaperture 32 can slideably receive thesecond end 26 of theshaft 12 and can slide generally parallel to the axis X on theshaft 12. As will be described, theaperture 32 can be shaped so as to be keyed against rotation about the axis X relative to theshaft 12. As thespacer 30 slides toward thefirst reamer 18, the spacer can eventually abut theshoulder 22 of theshaft 12. As such, theshoulder 22 can limit movement of thespacer 30 along the axis X in a direction generally toward thefirst reamer 18. Thesystem 10 can also include a separate retention member, such as a biased detent pin or other quick-connect coupling (not shown), that limits movement ofspacer 30 along the axis X in a direction generally away from thefirst reamer 18. As will be described, thespacer 30 maintains the first reamer 18 a predetermined distance away from other components of thesystem 10, and this predetermined distance can be varied on a patient-by-patient basis by interchanging thespacer 30 with another. - Furthermore, the
system 10 can additionally include asecond reamer 34. Thesecond reamer 34 can be generally tubular in shape and can be fluted in order to remove and reduce material during reaming operations. Thesecond reamer 34 can be fluted in either the left-hand or right-hand direction about the axis X; however, it will be appreciated that thesecond reamer 34 is fluted in the same direction as thefirst reamer 18. Also, thesecond reamer 34 can include anaperture 36, such as a through-hole, that extends therethrough. Theaperture 36 can include arounded portion 40 and aflat surface 38 as shown inFIG. 3 . Theaperture 36 can slideably receive theshaft 12 in order to couple thesecond reamer 34 to theshaft 12. More specifically, theflat surface 38 of thesecond reamer 34 can mate with theflat surface 16 of theshaft 12, and the roundedportion 40 of thesecond reamer 34 can mate with the roundedportion 14 of theshaft 12 such that thesecond reamer 34 continuously extends about and surrounds theshaft 12 as shown inFIG. 3 . Accordingly, thesecond reamer 34 can be substantially locked against rotation about the axis X (i.e., keyed to the shaft 12). However, it will be appreciated that the reamingsystem 10 can include any suitable anti-rotation component for coupling thesecond reamer 34 against rotation relative to the axis X of theshaft 12. It will also be appreciated that thespacer 30 can be similarly locked against rotation relative to theshaft 12. - The
second reamer 34 can slide from thesecond end 26 generally parallel to the axis X toward thespacer 30 and thefirst reamer 18. Also, thesecond reamer 34 can abut against thespacer 30 such that thespacer 30 limits movement of thesecond reamer 34 and maintains a predetermined amount of space between the first andsecond reamers system 10 can also include a separate retention member, such as a biased detent pin or other quick-connect coupling (not shown), that limits movement ofspacer 30 along the axis X in a direction generally away from thefirst reamer 18. - Furthermore, in some embodiments, the
system 10 can be used without thespacer 30 such that thesecond reamer 34 abuts directly against theshoulder 22 when coupled to theshaft 12. Moreover, in some embodiments, thesystem 10 can include a plurality ofsecond reamers 34 and/or a plurality ofspacers 30, which are each coupled to theshaft 12 at a respective location along the axis X. - As shown in
FIG. 1 , thefirst reamer 18 can have a maximum width W1 (diameter) that is less than a maximum width W2 (diameter) of thesecond reamer 34. More specifically, thefirst reamer 18 can be at least partially tapered and can have a maximum width W1 adjacent theshoulder 22. Likewise, thesecond reamer 34 can include a taperedportion 42 and an axiallystraight portion 43. Thesecond reamer 34 can have a maximum width W2 at the intersection between the taperedportion 42 and the axiallystraight portion 43. As will be discussed, the different widths W1, W2 and lengths of the first andsecond reamers system 10 can ream pockets (e.g., bores) that substantially match the geometry of an associated prosthetic device (FIG. 10 ) intended for implantation. - It will be appreciated that when the
second reamer 34 is coupled to theshaft 12, thesecond reamer 34 can be driven in rotation about the axis X simultaneously with thefirst reamer 18. More specifically, thefirst drive coupler 24 can be coupled to the driving device 28 (FIG. 5 ), and theshaft 12 can be drivingly rotated about the axis X. This, in turn, simultaneously rotates both the first andsecond reamers FIG. 5 , thefirst reamer 18 can be used to create a reamed distal pocket 52 (i.e., distal bore) in afemur 50 when the drivingdevice 28 rotates theshaft 12. Also, because thesecond reamer 34 rotates with thefirst reamer 18 and because thesecond reamer 34 is fluted in the same direction as thefirst reamer 18, thesecond reamer 34 can simultaneously create a reamed proximal pocket 54 (i.e., proximal bore) that is in communication with thedistal pocket 52 in thefemur 50. It will be appreciated that the distal andproximal pockets FIG. 10 ). The distal andproximal pockets spacer 30 can maintain the predetermined distance between the first andsecond reamers proximal pockets pockets - Furthermore, as shown in
FIG. 10 , thesystem 10 can be a modular kit that includes a plurality of differentfirst reamers 18,spacers 30, andsecond reamers 34. Thereamers spacers 30 can vary by length, width, material, or in any other suitable fashion. Thus, the medical professional can pick and choose from among thefirst reamers 18, thespacers 30, and thesecond reamers 34 for performing a reaming operation that substantially matches the geometry of the prosthetic that will be implanted. - Once the distal and
proximal pockets prosthetic members 53, 55 (FIG. 10 ) can be implanted within thefemur 50. For instance, in some embodiments, a distalprosthetic member 53 can be implanted within thedistal pocket 52, and a proximalprosthetic member 55 can engage the distalprosthetic member 53 and be implanted within theproximal pocket 54. - As shown in
FIG. 10 , theprosthetic members prosthetic system 57. Thesystem 57 can include a plurality of distal prosthetic members 53 (i.e., stems), each having different geometries (e.g., different lengths, widths, etc.). Thesystem 57 can further include a plurality of proximal prosthetic members 55 (i.e., bodies), each having different geometries (e.g., different lengths, widths, etc.). Each distalprosthetic member 53 can engage and fix to each of the proximalprosthetic members 55, for instance, by a Morse taper-type coupling. Thus, the surgeon can select and customize a distalprosthetic member 53 and a proximalprosthetic member 55 on a patient-by-patient basis. For instance, thesystem 57 can incorporate components from the commercially available ARCOS system, available from Biomet, Inc. of Warsaw, Ind. - Also, as shown in
FIG. 10 , the reamingsystem 10 can be directly associated geometrically with the modularprosthetic system 57. For instance, thesystem 10 can include a plurality offirst reamers 18 of different geometries (e.g., different lengths, widths, etc.), and eachfirst reamer 18 can have a geometry that substantially matches one of the distalprosthetic members 53. Likewise, thesystem 10 can include a plurality ofsecond reamers 34 of different geometries, and eachsecond reamer 34 can have a geometry that substantially matches one of the proximalprosthetic members 55. Furthermore, thesystem 10 can include a plurality ofspacers 30 of different lengths, each corresponding to the assembled distance between the distal and proximalprosthetic members prosthetic members first reamer 18,spacer 30, andsecond reamer 34 to ream thefemur 50. Because thefirst reamer 18,spacer 30, andsecond reamer 34 match theprosthetic members first reamer 18,spacer 30, andsecond reamer 34 are engaged together during reaming, the reamed pockets 52, 54 (FIG. 5 ) can be very accurately formed simultaneously. As such, thesystem 10 ensures that theprosthetic members femur 50. - Also, as shown in
FIG. 4 , thesecond reamer 34 can be alternatively and removably coupled to asecond drive coupler 44. For instance, thesecond reamer 34 can be removably coupled to thesecond drive coupler 44 via a biased detent pin (not shown) or in any other suitable fashion. Also, thesecond drive coupler 44 can be included on a shaft that slidably receives thesecond reamer 34. Accordingly, thesecond reamer 34 can be drivingly coupled to the drivingdevice 28 separate from thefirst reamer 18 when necessary. For instance, if the distal prosthetic member 53 (FIG. 10 ) is already inserted into the distal pocket 52 (FIG. 5 ), and theproximal pocket 54 needs to be widened, thesecond reamer 34 can be coupled to thesecond drive coupler 44 and drivingly attached to the drivingdevice 28 to widen theproximal pocket 54. In some embodiments, theaperture 36 of thesecond reamer 34 can be wide enough such that thesecond reamer 34 can fit partially over and rotate relative to the distalprosthetic member 53 in order to ream out theproximal pocket 54. Thus, the surgeon conveniently has the option to create thepockets - Accordingly, the
system 10 allows the medical professional to reampockets femur 50 or other anatomical feature of a patient with a single modular system in one step. It will be appreciated that thereamers shaft 12 to match the geometry of modularprosthetic members reamers pockets system 10 can be very convenient and time-efficient for the medical professional when reaming thefemur 50 or other suitable anatomical feature. Also, thesystem 10 can be varied according to the patient's anatomy, according to theprosthetic members system 10 can ream thepockets femur 50. - Referring now to
FIGS. 6 , 7, 8, and 11 another exemplary embodiment of thesystem 110 is illustrated. Components that correspond to those ofFIGS. 1-5 are indicated by corresponding reference numerals, increased by 100. - As shown, the
system 110 can include afirst member 160 and asecond member 162. Thefirst member 160 can include a first shaft 112 (FIG. 7 ) with a first reamer 118 (e.g., a distal reamer) and a first drive coupler 124 (FIG. 7 ) fixed at opposite ends. Thesecond member 162 can also include asecond shaft 164 with a second reamer 134 (e.g., a proximal reamer) and asecond drive coupler 144 fixed at opposite ends. - The
first reamer 118 can be elongate and fluted. As shown inFIGS. 6 , 7, and 11, the first reamer 11 8 can have a slight taper such that the width (i.e., diameter) increases along the axis X toward thefirst shaft 112. Moreover, thefirst reamer 118 can include ashoulder 137. - The
first shaft 112 can be elongate and can include afirst portion 139 and asecond portion 141. The first andsecond portions second portion 141 can be wider (i.e., can have a larger diameter) than thefirst portion 139. Thesecond portion 141 can be disposed between thefirst reamer 118 and thefirst portion 139 of theshaft 112. - Also, the
second reamer 134 can be elongate and fluted and can be tapered. Thesecond reamer 134 can also include aleading end 135 that is beveled so as to improve reaming operations. - In some embodiments, the
second member 162 can include depth indicators 192 (FIGS. 6 and 11 ). Likewise, thefirst member 112 can include depth indicators 193 (FIG. 11 ). Thedepth indicators depth indicators respective member member - The
first member 160 can be removably coupled to thesecond member 162. For instance, thesecond member 162 can be hollow so as to slidably receive thefirst drive coupler 124 and thefirst shaft 112, and such that the first andsecond members FIG. 7 . As shown inFIG. 7 , thefirst member 160 substantially fills and mates with thesecond member 162. When coupled, thefirst reamer 118 extends out from thesecond member 162 and is disposed at a distance axially away from thesecond reamer 134. Also, as shown inFIGS. 6 and 7 , theleading end 135 of thesecond reamer 134 can be disposed directly adjacent theshoulder 137 of thefirst reamer 118 when the first andsecond members leading end 135 of thesecond reamer 134 can additionally include teeth 147 (FIGS. 6 and 11 ) that increase the cutting ability of thesecond reamer 134. - Also, as shown in
FIGS. 8 and 11 , thefirst shaft 112 can include a plurality of firstflat surfaces 116, and as shown inFIG. 8 , thesecond shaft 164 can include a plurality of secondflat surfaces 138. For instance, as shown inFIGS. 8 and 11 , thefirst shaft 112 can include two firstflat surfaces 116 that are disposed symmetrically on opposite sides of the axis X, between the first andsecond portions first shaft 112. Thesecond shaft 164 can include two corresponding secondflat surfaces 138 that are disposed symmetrically on opposite sides of the axis X. Theflat surfaces second members - Moreover, the
first shaft 112 can additionally include a shoulder 122 (FIGS. 7 and 11 ). Theshoulder 122 can be included between the first andsecond portions first shaft 112. As shown inFIG. 7 , thesecond member 162 can abut against theshoulder 122 to limit movement of thesecond reamer 134 axially toward thefirst reamer 118. - Furthermore, in some embodiments, the
second member 162 can include a retention member 166 (FIG. 7 ) that limits movement of thesecond reamer 134 away from thefirst reamer 118. Theretention member 166 can be a quick-connect coupling of a known type. More specifically, theretention member 166 can be operably supported on thesecond member 162, and theretention member 166 can include asleeve 168, a biasingmember 170, and a bearing 172 (FIG. 7 ). Thesleeve 168 can be ring-shaped and can be slidably received on thesecond shaft 164 to slide axially on thesecond shaft 164. The biasingmember 170 can be of any suitable type, such as a coiled spring and can be received on thesecond shaft 164. The bearing 172 can be of any suitable type, such as a plurality of ball bearings that are spaced evenly around thesecond shaft 164 and that are biased radially outward from the axis X. The biasingmember 170 can bias thesleeve 168 toward thesecond drive coupler 144. Also, thesleeve 168 can include aramp 174. - As the
sleeve 168 moves away from thesecond reamer 134, theramp 174 cams the bearing 172 toward the axis X and into agroove 180 formed on the first shaft 11 2 of thefirst member 160. As such, thefirst member 160 is limited against movement in a direction parallel to the axis X relative to thesecond member 162. Furthermore, as thesleeve 168 moves toward thesecond reamer 134, thebearing 172 is able to bias away from the axis X and out of thegroove 180, thereby releasing thefirst member 160 from thesecond member 162. - Accordingly, the
retention member 166 conveniently couples and de-couples the first andsecond members retention member 166 can be used to limit movement of thesecond member 162 in both axial directions relative to thefirst member 160. - Thus, the first and
second members system 110 can be used to simultaneously ream a plurality of regions of afemur 50, similar to the embodiment ofFIG. 5 . It will be appreciated that aspacer 30 of the type shown inFIGS. 1-5 can be included between the first andsecond reamers second reamers - Also, the first and
second members femur 50 as discussed above. For instance, thefirst member 160 can be used separate from thesecond member 162 to perform distal reaming of a femur. Next, as shown inFIG. 9 , thesecond member 162 can be used after a distalprosthetic member 153 has been implanted in thefemur 150. More specifically, analignment rod 189 can be removably coupled to the distalprosthetic member 153, and thesecond member 162 can slide over and receive thealignment rod 189. Thealignment rod 189 ensures that thesecond member 162 is aligned substantially coaxially relative to the distalprosthetic member 153; however, thesecond member 162 remains free to move axially and rotate about the axis X relative to thealignment rod 189. Then, thesecond member 162 can be used to proximally ream thefemur 150 and create space for implantation of the proximal prosthetic member (not shown). - Also, the
second member 162 can include anopening 194, and thealignment rod 189 can include avisual indicator 196 that appears within theopening 194 when thesecond member 162 is at a predetermined depth within thefemur 150. Accordingly, thesecond member 162 can ream thefemur 150 very accurately, even when separate from thefirst member 160. - In addition, as shown in
FIG. 12 , thesystem 110 can include anextension member 184. Theextension member 184 can be used for reaming with thefirst member 160 separate from thesecond member 162. Theextension member 184 can be elongate and axially straight. Theextension member 184 can include ashaft 185 with athird drive coupler 186 and aretention member 187 on opposite ends. Theretention member 187 can be of a quick-connect type, similar to theretention member 166 described above and shown inFIGS. 6 , 7, and 11. Theshaft 185 can also includedepth indicators 188, such as inscribed gradations with numbers. - As shown in
FIG. 12 , theretention member 187 can couple to thefirst member 160 in a manner similar to theretention member 166 described above. Also, thethird drive coupler 186 can couple to adriving device 28 of the type described above and shown schematically inFIG. 5 . Thus, theextension member 184 can be removably coupled to the first member to effectively extend the reach of thefirst member 160 during distal reaming. As such, thefirst member 160 can be used to ream relatively deeply within thefemur 150. - It will be appreciated that the
system 110 can include a plurality ofextension members 184 of different axial lengths. As such, the surgeon can select anextension member 184 to perform distal reaming to a predetermined depth, corresponding to the length of the selectedextension member 184. - Now referring to
FIG. 13 , another exemplary embodiment of thesystem 210 is illustrated. Components that correspond to those ofFIGS. 1-5 are indicated by corresponding reference numerals, increased by 200. - The
system 210 can include ashaft 212 having afirst reamer 218 fixed at one end and adrive coupler 224 fixed at an opposite end. Theshaft 212 can be substantially similar to theshaft 12 of the embodiments ofFIGS. 1 and 2 , except theshaft 212 can include at least onedetent button shaft 212 can include a plurality ofdetent buttons detent buttons shaft 212 can include quick-connect couplings other than thedetent buttons - The
system 210 can also include asecond reamer 234. Thesecond reamer 234 can be substantially similar to thesecond reamer 34 of the embodiments ofFIGS. 1 and 2 , except thesecond reamer 234 can include anaperture 221. Theaperture 221 can receive one of thedetent buttons shaft 212 to fix thesecond reamer 234 in a longitudinal position on theshaft 212 as will be discussed in greater detail below. Thesecond reamer 234 can also include arecess 223 that surrounds theaperture 221 that provides a comfortable surface for the user to depress thedetent button second reamer 234 from theshaft 212 as will be discussed in greater detail below. - Furthermore, the
system 210 can include athird reamer 245. Thethird reamer 245 can be tapered so as to have a distal width W3 that is substantially equal to the proximal width W1 of thefirst reamer 218 and to have a proximal width W4 that is substantially equal to the distal width W5 of thesecond reamer 234. Thethird reamer 245 can also include anaperture 240, such as a through hole, that receives theshaft 212. Furthermore, ashaft portion 251 can be fixed on a proximal end of thethird reamer 245. Theshaft portion 251 can be keyed to theshaft 212 like the embodiments discussed above to inhibit relative rotation of theshaft 212 andthird reamer 245. Furthermore, thethird reamer 245 can be fluted in the same direction as the first andsecond reamers - To assemble the
system 210, thethird reamer 245 can slide longitudinally along the axis X from theproximal end 226 of theshaft 212 toward thefirst reamer 218. Then, thesecond reamer 234 can slide longitudinally along the axis X from theproximal end 226 of theshaft 212 toward thefirst reamer 218 such that thethird reamer 245 is disposed between the first andsecond reamers aperture 221 of thesecond reamer 234 can receive one of thedetent buttons second reamer 234 in an axial position on theshaft 212. The first andsecond reamer third reamer 245 and fix thethird reamer 245 in an axial position on theshaft 212 as well. Furthermore, in some embodiments, thethird reamer 245 can include an aperture for receiving one of thedetent buttons third reamer 245 axially. - Then, the first, second, and
third reamers reamers system 210, the user presses thedetent button third reamers first reamer 212. - Accordingly, it will be appreciated that the
system 210 can be assembled and disassembled quickly and conveniently. Also, it will be appreciated that thethird reamer 245 can be optionally used. For instance, thesecond reamer 234 can be coupled to theshaft 212 independent of thethird reamer 245 and fixed in an axial position relative to theshaft 212 by one of thedetent buttons detent buttons system 210 can provide substantial versatility. - Moreover, the foregoing discussion discloses and describes merely exemplary embodiments of the present disclosure. One skilled in the art will readily recognize from such discussion, and from the accompanying drawings and claims, that various changes, modifications and variations may be made therein without departing from the spirit and scope of the disclosure as defined in the following claims. For instance, the sequence of the blocks of the method described herein can be changed without departing from the scope of the present disclosure.
