PATENIED SE?! 4 I971 INVENTOR. I B I Richard 5. Gilbert BY /8 i4, 4 Attorneys ORTHOPEDIC SCREW DRIVING MEANS BACKGROUND OF THE INVENTION Screws are used in orthopedic surgery for joining bones 5 together and for attaching foreign members, such as stainless steelplates, to bones. The screws are generally threaded into and anchored in the bones, and it is frequently necessary for the surgeon or person inserting the screws to perform the driving operation with only one hand. It is therefore desirable, and in many cases necessary, that the screws be started and driven by means of a screwdriver which is capable of holding the screws in a relatively rigid position.

Screws heretofore used in orthopedic surgery have been provided with heads having conventional slots, such as straight slots, cross-slots, and phillips heads. Holding screwdrivers which have been provided for driving the screws generally include both a blade for engaging the slot in the screwhead and a plurality of claws or fingers for gripping the screwhead. These claws or fingers extend over the sides of the screwhead and engage either the side or the lower portion of the screwhead, making it impossible to complete the driving of the screw while the holding claws are engaged with its head. Most holding screwdrivers include means for disengaging the claws and completing the driving of the screw with the claws in a retracted position. Such arrangement presents a problem in that the claws are larger than the head of the screw and obstruct the surgeons view of the head as it is seated. Consequently, the surgeon usually finds it necessary to change to a second screwdriver to complete the driving of the screw. There is a need for a solution to these and additional problems in the art.

SUMMARY AND OBJECTS OF THE INVENTION The present invention provides a combination of an orthopedic screw and driving means which enables the screw to be started and driven in a single continuous operation. The head of the screw is provided with a plurality of slots adapted for receiving the pinching blades of the driving means in such a manner that the screw and driving means are locked together without the driving means extending beyond the lateral extremities of the screwhead.

In general, it is an object of the present invention to provide a new and improved combination of an orthopedic screw and driving means.

Another object of the invention is to provide a combination of the above character which enables the screw to be started and driven in a single continuous operation.

Another object of the invention is to provide a combination of the above character wherein no part of the driving means overhangs the lateral extremities of the screwhead to interfere with the complete driving of the screw.

Another object of the invention is to provide a combination of the above character wherein the person using the combination can see the lateral extremities of the screwhead at all times during the driving operation.

Additional objects and features of the invention will appear from the following description in which the preferred embodiment is set forth in detail in conjunction with the accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWING FIG. 4 is a side elevational view of the portion of the. driving.

means indicated by the line 4-4 in FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the preferred embodiment, the combination of the present invention consists of an orthopedic screw designated generally by reference numeral 10 and driving means designated generally by reference numeral 11. Like reference numerals are used to indicate corresponding parts in all figures of the drawing.

The orthopedic screw 10 includes an axially extending threaded stem 12 and a head 13 at one end of said threaded stem.

The threaded stem 12 comprises a substantially cylindrical shank 14 having a helical thread 15. The thread 15 is shown as a spaced thread since this is the type of thread that is commonly used in bone screws. However, as will be apparent to one skilled in the art, other types of threads may be used in the present invention. In some applications, it may be desirable to taper the thread toward its leading end or to use a conically tapered shank.

The head 13 is illustrated as a conventional oval head having a rounded upper surface 17 and a conical lower portion I8. Lower portion 18 is suitable for countersinking and has an included angle of the order of 82 Neither this angle nor the shape of the head is critical to the invention.

The screwhead 13 is provided with two slots 19 which are adapted for receiving the blades of the driving means in a manner hereinafter described in detail. Slots 19 are formed in the upper surface 17 of the screwhead. The openings of slots 19 are substantially parallel to each other and are equally spaced from the axis of the screw. The remaining portions of slots 19 are inclined with respect to the axis in such a manner that the lower portions of the slots are closer to the axis and to each other than are the upper portions of the slots. While the exact angle of inclination is not critical, particularly satisfactory results are obtained when the slots are inclined to the axis at an angle of the order of 30 In the preferred embodiment, slots 19 do not extend all the way to the edges of head 20, to assure that the blades of the driver means cannot slip transversely out of the slots while the screw is being driven. As illustrated, the slots 19 have a generally rectangular cross section, as can best be seen in FIG. 2, and a rounded bottom 21. This slot configuration is conveniently formed with a conventional milling cutter.

Tapping means, not shown, can be provided at the end of threaded stem 12 opposite head 13. This tapping means can be any conventional type of self-tapping means which is suitable for cutting threads in bone.

The screw can be fabricated of any material which is both biologically inert and otherwise suitably for use with screws. Suitable materials include stainless steel and monel metal.

In the preferred embodiment, driving means 11 comprises generally a pair of blades 26, a sleeve 27, a resilient member 28, a handle 29, and an adjusting capnut 30.

The blades 26 extend axially of driving means 11 and are adapted for pinching together to engage and hold screwhead 13. The combined cross section of the blades is generally circular.

The blades 26 have tip portions 31 at the lower ends thereof for engaging the slots in the head of the screw 10. In the preferred embodiment, these tip portions 31 are substantially straight members which are inclined at an angle with respect to the axis of the driving means. This angle of inclination corresponds to the inclination of the slots in the screwhead so that when the driver blades are engaged with the screwhead, the axes of the screw and driving means are aligned. Tip portions 31 have rounded lower extremities 33 which conform generally to the contour of the screw slots. It has been observed that the more closely the contours of tip portions 21 and slots 19 are matched, the more rigidly the screw is heldby the driving means.

Additional rigidity is provided by shoulder portions 34 which are located adjacent to tip portions 31 of blades 26. Shoulder portions. 34 have a contour corresponding to the contour of the upper surface 17 of the screwhead.

The blades 26 also include conically tapered portions 36. These conical portions extend radially outward and are located toward the lower ends of the blades. They cooperate with sleeve 27 and resilient member 28 to urge blades 26 together in a manner hereinafter described.

The upper ends of blades 26 are provided with threads 37 for engaging corresponding threads on adjusting nut 30. A key 260 is also provided proximate to the upper end of blades 26 for engaging a keyway 29b in handle 29.

The sleeve 27 is substantially cylindrical in shape and surrounds a central portion of blades 26. The lower end 41 of sleeve 27 rests against or slidably engages the surfaces of tapered portions 36, and the inner surface 42 of end 41 is beveled at an angle corresponding to the taper of conical portions 36. The upper end 43 of sleeve 27 is provided with an annular recess 44 for receiving the lower end of resilient member 28, as is more fully discussed hereinafter. In the preferred embodiment, knurling 46 is provided on the outer surface of sleeve 27 to provide a better surface for gripping.

The resilient member 28 surrounds blades 26 near the upper ends thereof. In the preferred embodiment, resilient member 28 is a conventional compression spring. The lower end of resilient member 28 engages recess 44 in sleeve 27, and the upper end is constrained by handle 29 and adjusting nut 30.

Handle 29 is generally cylindrical in shape and surrounds resilient member 28 and the upper portion of sleeve 27. Handle 29 includes an annular upper shoulder portion 29a, which engages the upper end of resilient member 28 and the lower surface of nut 30. Shoulder 29a includes a keyway 29b which cooperates with key 26a, locking blades 26 to handle 29 for rotation therewith, while permitting handle 29 to move axially with respect to blades 26.

Adjusting nut 30 is threadably mounted on the upper ends of blades 26 by means of threads 47 which engage threads 37 on blades 26. The lower surface 48 of nut 30 bears against the upper end of resilient member 28 through shoulder 29a of handle 29. Thus, nut 30 provides means for adjusting the tension in resilient member 28. As will be apparent to one skilled in the art, when nut 30 is adjusted to provide a tension in resilient member 28, sleeve 27 is urged downward against tapered portions 36 of blades 26, thereby urging blades 26 together.

Means is provided for causing blades 26 to separate whenever a force exerted by resilient member 28 is relieved. In the preferred embodiment, blades 26 are fabricated of a resilient material having cutaway portions, as indicated at 49. Thus, when the upper ends of blades 26 are held together by nut 30, the stresses in the blades urge the lower ends thereof to separate.

The dimensions of blades 26 and screwhead 13 are such that the person using the screw and driving means can see the lateral extremities of screwhead 13 throughout the entire driving operation. The lower portions of blades 26 have a combined cross-sectional area that is generally circular and smaller than the area defined by the upper surface 17 of screwhead 13. Further visibility can be provided by tapering the outer surfaces of blades 26 as indicated at 51. Conical portions 36 are located sufficiently far from the lower ends of blades 26 that they do not obstruct the user's view of the screwhead.

The operation of the combination screw and driving means can now be briefly described as follows: Let it be assumed that nut 30 has been adjusted to provide sufficient compression of resilient member 28 to force blades 26 together. Blades 26 can be separated by depressing nut 30 and handle 29 with respect to sleeve 27 to relieve the force exerted by resilient member 28 on conically tapered portions 36. This is conveniently cone by holding sleeve 27 with the palm and fingers of the hand and exerting a downward pressure on nut 30 with the thumb of the same hand. When blades 26 are thus separated, tip portions 31 can be inserted into slots 19 of screwhead l3. Thereafter,

when the thumb pressure is removed from nut 30, resilient member 28 expands, urging blades 26 to pinch together to provide an interlocking engagement between blades 26 and screwhead 13. As blade tips 31 pinch together against the inclined inner side surfaces of slots 19, the upper surface 17 of screwhead 13 is pressed firmly against shoulder portions 34 of blades 26. With blades 26 thus engaging screwhead l3, screw 10 is rigidly held by driving means 11 and can be started and driven in a single operation. Blades 26 are disengaged from screwhead 13 simply by depressing nut 30 with respect to sleeve 27 and withdrawing the tip portions from the slots.

The particular driver blade and screw slot configurations described hereinbefore are those employed in the presently preferred embodiment of the invention. However, other configurations can be used. Examples of other suitable slot configurations are described in my copending application Ser. No. 805,441, filed of even date.

Although the invention has been described herein with specific reference to the driving screws in orthopedic surgery, it will be appreciated that the invention is adaptable for use with other types of screws, such as machine screws, wood screws and sheet metal screws. Likewise, while the invention has been illustrated with reference to oval head screws, it is not limited thereto.

From the foregoing, it will be apparent that there has been provided a new and improved combination of a screw and driving means enabling an orthopedic screw to be started and driven in a single continuous operation.
