In an unloaded position, shoulder 45 engages an inner ledge 53 of thumb slide 52 and when thumb slide 52 is moved in the proximal direction by an operator, shaft 36 is also retracted. To move shaft 36 to the loaded position, thumb slide 52 is moved in the proximal direction until shoulder 45 slides beyond ledge 49 of button 48 and ledge 49 engages shoulder 45 , thereby locking shaft 36 in the loaded position. This shaft retraction will also compress firing spring 38 .

Description
- Priority of Provisional Application No. 60/330,977, filed on Nov. 5, 2001 is claimed under 35 U.S.C. §119 and priority of U.S. patent application Ser. No. 09/866,841, filed on May 30, 2001 and PCT Application No. PCT/US02/16656, filed on May 28, 2002 is claimed under 35 U.S.C. §120, the entire contents of which are incorporated by reference.
- The present invention relates to a device for the storage and dispensing of osteosynthetic fixation elements, and in particular to a device for attaching fixation elements to bone.
- In the surgical treatment of fractures in the maxillofacial area, as well as fractures of the foot and hand, a trend toward preferring ever-smaller implants can clearly be noted. The reason for this is the generally increased understanding of the biomechanical bases of osteosynthesis. In the field of treating maxillofacial fractures, more attention can be paid to the cosmetic results of osteosynthesis, thanks to the miniaturization of implants. In the field of hand surgery, restrictions on movement in the area of the fingers can be avoided. In this regard, smaller osteosynthetic implants in the fingers can be placed under the tendons. In the case of an implant with a large cross-section, the tendons need no longer be extended to their full length.
- The dimensions of some smaller implants (screws, plates and tacks) are in the range of about 0.8 mm to about 2.0 mm. Problems in the area of packaging, storage and manipulation during surgery arise due to this miniaturization. Handling in the operating room, particularly in the maxillofacial area, has proved difficult. Depending on the degree of severity of the fracture or correction, up to 40 bone fixation elements, such as tacks or screws, may be required. These screws must be taken individually by the operating room nurse from a so-called screw rack, checked for length, placed on a screwdriver and given to the surgeon. The surgeon must, in turn, insert them through the osteosynthesis plate into pre-drilled screw holes. During the transfer of the screw and the attempted insertion of the screw, it often falls off the screwdriver, into the wound or onto the operating room floor. The attempt to find a lost screw is often excessively time-consuming, given their dimensions and extends the time spent in surgery. The frequent loss of screws in the operating room, and during packing and sterilization, causes unnecessary costs for the hospital. Thus, it is desirable to have a simple device that can be operated with one hand, thereby freeing the operator's other hand to align the fixation element or perform other tasks
- An additional problem in dealing with mini-screws arises during their implantation. After the surgeon has selected the osteosynthesis plate proper for the fracture in question, a plate is positioned over the fracture. A hole is then drilled for the screw (0.5-1.5 mm diameter) through one of the plate holes. Commonly, problems arise in controlling the amount of force applied during the insertion of the screw and or tack. For example, if a surgeon is required to insert a screw or tack with manual force, the manula force could be transmitted to the surrounding bone, which could bend thin and/or flexible bone in young patients.
- Also, problems such as surgical gloves tearing or hand pinching can arise if the insertion device has parts that move externally during the firing of the device. Thus, a need exists for an insertion device that minimizes the manual force exertion required and to minimize the gross forces applied to the surrounding bone during insertion.
- The present invention relates to a device for attaching fixation elements to bone, including a longitudinal member extending along a longitudinal axis from a proximal end to a distal end and having a channel extending therein adapted for receiving at least one fixation element. A shaft extends within the channel and is positioned coaxially within at least a portion of the longitudinal member and at least a portion of the shaft is retained within the longitudinal member and a distal end configured and adapted to contact at least a portion of the fixation element received within the longitudinal member. A spring is positioned adjacent the shaft for resiliently biasing the shaft in an axial direction and the shaft is moveable with respect to the longitudinal member to drive the fixation element into bone.

- Referring to FIG. 1, a preferred fixation
element insertion device 10 according to the present invention generally includes a longitudinal member extending along alongitudinal axis 12 from aproximal end 14 to adistal end 16 and having achannel 18 extending therein. The insertion device is preferably used to drive an osteosynthetic fixation element, such as a resorbable tack, into bone tissue. Channel 18 is configured and dimensioned to receive at least one fixation element for storage, transport, dispensing, and or insertion into bone. - Referring to FIG. 2, one preferred fixation element compatible with
insertion device 10 comprises atack 20 having ashaft 22 integral with ahead 24 at a proximal end thereof. The distal end ofshaft 22 has aconical nose 26 to facilitate the insertion oftack 20 into bone tissue. A plurality ofcircular ribs 28 extend radially from the exterior ofshaft 22 to prevent the removal of the tack from the bone tissue after it has been inserted.Head 24 has an outer diameter greater than the diameter ofshaft 22 and contacts or rests against the bone or bone plate when the tack is inserted into bone tissue. In the preferred embodiment, the tack is made from a resorbable material so that it remains in the bone tissue temporarily and is absorbed by the body. In alternate embodiments,tack 20 can have numerously different configurations and dimensions. Also, different types of fixation elements altogether can be used withinsertion device 10. For example, biocompatible screws, nails, anchors, rivets, or other similar implants can also be inserted usinginsertion device 10. - Referring again to FIG. 1,
insertion device 10 has ahandle 30 at the proximal end that is configured to conform to the shape of a person's hand or palm for easily gripping the device and anapplicator extension 32 for holding and dispensing the fixation element. Acentral channel 70 extends withinhandle 30 and throughextension 32 and is in communication withchannel 18 atdistal end 16.Channel 18 generally comprises a socket defined at thedistal end 16 and anelongate applicator extension 32 extends betweendistal end 16 and handle 30.Extension 32 can be a unitary extension or can include multiple parts. Socket orchannel 18 fits about the proximal end offixation element 20 to holdelement 20 ininsertion device 10 by an interference or friction fit. In the embodiment of FIG. 1, anindividual tack 20 can be held atdistal end 16 andhead 24 oftack 20 is preferably held within the socket orchannel 18 while theshaft 22 oftack 20 projects outside thereof, as shown in FIG. 3. At the distal end ofextension 32 is a pronged tip 34 for retaining a fixation element. Pronged tip 34 is generally flexible and when the distal end ofextension 32 is pressed, the prongs 34 ofsleeve 32 flex around the head of a fixation element to pick up and retain the element. In this way, it is possible to pick up a relatively small fixation element in a simple, single action. - A shaft member36 and a firing spring 38 are housed within
central channel 40. Shaft member 36 extends longitudinally withinhandle 30 andextension 32 and is preferably moveable alongaxis 12 with respect to handle 30 andextension 32. Firing spring 38 is positioned at the proximal end ofhandle 30 and is compressible between a force adjustment dial 39 atproximal end 14 and a proximal end of shaft member 36, biasing shaft member 36 in the distal direction. Shaft 36 is generally cylindrical and includes abase portion 42 that slidingly engages the interior ofchannel 40 withinhandle 30, a mid-section 44 having a smaller diameter thanbase portion 42, and a tip portion 46 having a smaller diameter than mid-section 44. A first shoulder 43 is positioned at the transition ofbase portion 42 and mid-section 44 and a second shoulder 45 is positioned at the transition of mid-section 44 and tip portion 46. - Shaft36 is moveable from a loaded position (shown in FIG. 1) to an unloaded position for inserting a fixation element into bone. An activation button 48 extends within
channel 40 for activating the movement of shaft 36 from a loaded position to an unloaded position. Button 48 is positioned along a portion ofhandle 30 and partially extends withinchannel 40 for engaging shaft 36. Referring to FIG. 1, when shaft 36 is in the loaded position ledge 49 at the proximal end of button 48 engages second shoulder 45 preventing shaft 36 from moving in the distal direction or to the unloaded position. When button 48 is depressed by an operator, ledge 49 is moved out of engagement with shoulder 45, thereby permitting shaft 36 to move in the distal direction under the force exerted by firing spring 38 on shaft 36. As a result, tip portion 46 of shaft 36 is advanced in the distal direction to force fixation element out ofextension 32 and shaft 36 is moved to an unloaded position. - In a preferred embodiment, button48 is pivotably positioned about a pin 47 and the distal portion of button 48 is biased radially outward by a
spring 50 so that ledge 49 at the proximal portion of button 48 is biased inward toward engagement with shoulder 82. In this regard, a collar 51 is preferably positioned withinhandle 30 for engagingspring 50 in the radial direction and permitting mid-section 44 of shaft 36 to slide therethrough without engaging spring 51. When button 48 is depressed, ledge 49 is pivoted radially outward and out of engagement with shoulder. In alternate embodiments, different button assemblies or triggering mechanisms can be used. - In a preferred embodiment, a
thumb slide 52 is positioned along a portion ofhandle 30 opposite activation button 48 and is moveable in the longitudinal direction for moving shaft 36 from an unloaded to a loaded position.Thumb slide 52 partially extends withinchannel 40 for engaging shaft 36 and moving shaft 36 in the longitudinal direction. In an unloaded position, shoulder 45 engages an inner ledge 53 ofthumb slide 52 and whenthumb slide 52 is moved in the proximal direction by an operator, shaft 36 is also retracted. To move shaft 36 to the loaded position,thumb slide 52 is moved in the proximal direction until shoulder 45 slides beyond ledge 49 of button 48 and ledge 49 engages shoulder 45, thereby locking shaft 36 in the loaded position. This shaft retraction will also compress firing spring 38. In a preferred embodiment, aspring 54 is housed withinhandle 30 andbiases thumb slide 52 in the distal direction and once shaft 36 is in the loaded position, the thumb slide is released and returns to its resting position. Once shaft 36 is again in the loaded position, another tack can be inserted into theextension 32. - Referring to FIGS.3-4, once the insertion device is loaded, the insertion device can be used to fasten a
plate 56 or other device to a bone 57. In operation, ahole 58 is pre-drilled in the bone tissue at the desired insertion location and theinsertion device 10 is placed adjacent the insertion location and the tack is aligned withhole 42. The activation button 48 is depressed to release shaft 36, and shaft 36 is driven in the distal direction by the force of firing spring 38 thereby drivingtack 20 into the bone tissue. As shown in FIG. 4, oncetack 20 is inserted into bone,insertion device 10 is withdrawn from the insertion location and tack 20 is separated fromchannel 18. When theinsertion device 10 is withdrawn, theforces holding shaft 22 oftack 20 to bone 57 are greater than the forces of the interference fit betweenhead 24 andchannel 18 so thathead 24 oftack 20 is separated fromdistal end 16, leavingtack 20 secured to the bone. Thedevice 10 can then be reloaded by moving the thumb slide in the proximal direction as explained above and inserting slightly smaller external dimensions than the internal dimensions ofcover 78 so that the proximal end of sleeve 82 can be inserted into the distal end ofcover 78 and sleeve 82 can move in the axial direction with respect to cover 78. As best seen in FIG. 9, sleeve 82 can include prongs that interlock with ridges on the interior ofcover 78 so that when sleeve 82 is inserted intocover 78, sleeve 82 is not inadvertently removed fromcover 78 in the distal direction. In a preferred embodiment, sleeve 82 has prongs 84 that are flexible and are collapsible or bendable into the interior of sleeve 82 so that sleeve 82 can be removed fromcover 78 for cleaning, disassembly, or replacement. Prongs 84 are biased radially outwardly so that sleeve 82 can be easily reattached by simply pushing the sleeve into the cover in the proximal direction. The distal end of sleeve 82 preferably has a pronged tip similar to that described previously for retaining a fixation element. - A
central channel 90 extends withinhandle 72 and throughextension 74 and houses a firing spring 91 and ashaft member 92 similar to the embodiment of FIG. 1. Firing spring 91 is biased between force adjustment dial 93 and the proximal end ofshaft 92. Adjustment dial 93 includes aknob 100 with internal threading that engages an externally threadedadjustment slider 102 that is slidably housed withinchannel 90. Whenknob 100 is rotated,adjustment slider 102 slidably moves withinchannel 90 and compresses or decompresses spring 91 for adjusting the amount of force that is exerted onshaft 92 and consequently the tack during insertion. A pair ofknob retaining screws 104 extend radially inward from the exterior ofhandle 72 and engage a circular groove inknob 100 for retainingknob 100 in the proximal end ofhandle 72. Aguide screw 106 extends inward fromhandle 72 and engage a longitudinal groove inadjustment slider 102 to prevent the slider from rotating. -
Shaft 92 extends longitudinally withinhandle 72 and is generally identical to shaft 36 described above, moving between a loaded and an unloaded position.Shaft 92 includes abase portion 94, a mid-section 96 having a smaller diameter thanbase portion 94, and atip portion 98 having a smaller diameter thanmid-section 96. A first shoulder 95 is positioned at the transition of base portion 95 andmid-section 96 and a second shoulder 97 is positioned at the transition ofmid-section 96 andtip portion 98.Device 70 includes anactivation button 108 similar to button 48 described above for facilitating movement ofshaft 92 from the loaded to the unloaded position in the same fashion as described with respect to the embodiment of FIG. 1. To moveshaft 92 from the unloaded to the loaded position, holding sleeve 82 andtip portion 98 ofshaft 92 is retracted in the proximal direction until shoulder 97 ofshaft 92 slides beyondbutton 108 and the button engages shoulder 97, thereby lockingshaft 92 in the loaded position in a similar fashion to button 48 described above. Also,insertion device 70 preferably has aspring 80 housed withinspring cover 78 that biases holding sleeve 82 in the distal direction and onceshaft 92 is in the loaded position, the holding sleeve is released and returns to its resting position. In this way,shaft 92 can be easily moved from the unloaded to the loaded position, by depressingdevice 70 in the distal direction against a solid object, such as a table or a surgeons hand. In all other respects, the method of operation or use ofdevice 70 is similar to the method described above with respect todevice 10. - Referring to FIGS.10-11, another embodiment of an
insertion device 110 is shown that has yet another alternative loading mechanism. In all other respects,device 110 is similar todevice 70 described previously.Insertion device 110 has acam 112 for movingshaft 92 from the unloaded to the loaded position. In this embodiment,shaft 92 haspins 114 extending outwardly therefrom that engage aninternal ramp 116 withincam 112 and whencam 112 is rotatedpins 114 slide along ramp 1116 in the proximal direction and thereby moveshaft 92 in the proximal direction andshaft 92 is retracted until shoulder 97 ofshaft 92 slides beyondbutton 108 and the button engages shoulder 97, thereby lockingshaft 92 in the loaded position in a similar fashion to button 48 described above. Aftershaft 92 is locked into the loaded position,cam 112 is rotated to provide clearance forpins 114 to move in the distal direction during the unloading or firing movement ofshaft 92. - While it is apparent that the illustrative embodiments of the invention herein disclosed fulfill the objectives stated above, it will be appreciated that numerous modifications and other embodiments may be devised by those skilled in the art. Therefore, it will be understood that the appended claims are intended to cover all such modifications and embodiments which come within the spirit and scope of the present invention.
