Abstract

An apparatus for holding a surgical broach during a surgical broaching procedure comprises a handle body with a handle bearing surface formed on one end of the body, an elastically deformable link member, and a loading arrangement connected to the handle body. The loading arrangement is adapted to apply a tensile connecting force on the link member and the link member is adapted to apply the connecting force to the broach to be connected to the handle. The connecting force applied to the broach by the link member pulls the broach toward the handle body with the handle bearing surface mating with a corresponding bearing surface formed on the broach. The broach includes a latch surface by which the connecting force is applied to the broach with the link member.

Claims

1. An apparatus for holding a surgical broach during a surgical broaching procedure, the apparatus comprising:

(a) a handle body;

(b) a handle bearing surface formed on a broach holding end of the handle body, the handle bearing surface being adapted to mate with a corresponding bearing surface formed on a surgical broach when the broach is in a broaching position with respect to the handle body;

(c) an elastically deformable link member having a catch surface formed thereon and adapted to catch on a latch corner formed on the broach, the link member for catching on the latch corner of the broach to apply a connecting force between the broach and the handle body when the broach is in the broaching position, and elongating elastically in response to the connecting force; and

(d) an elongated loading member pivotally connected to the handle body and to the link member for loading and maintaining the connecting force on the link member so that the link member holds the broach in the broaching position with respect to the handle body.

2. The apparatus of claim 1 wherein:

(a) the link member has an arcuate shape such that a tensile force applied at either end thereof elastically straightens the link member.

3. The apparatus of claim 1 further comprising:

(a) link positioning means connected to the handle body for maintaining the end of the link member that is not connected to the lever positioned in an area adjacent to the handle bearing surface.

4. The apparatus of claim 1 wherein:

(a) the handle bearing surface includes a first surface lying in a first plane and a second surface lying in a second plane, the first and second planes intersecting to form generally a v-shape and each intersecting a longitudinal axis of the handle body at an acute angle.

5. The apparatus of claim 1 wherein:

(a) the handle bearing surface includes a plurality of discrete surfaces, each discrete surface lying in a different plane and the planes intersecting to form a plurality of v-shapes, and each plane intersecting a longitudinal axis of the handle body at an acute angle.

6. In a surgical tool holding apparatus having a handle body by which a surgical tool may be manipulated during a surgical procedure, the improvement comprising:

(a) an elastically deformable link member having a catch surface formed thereon and adapted to catch on a latch corner formed on the surgical tool, the link member for catching on the latch corner of the surgical tool to apply a connecting force between the surgical tool and the handle body when the tool is in a connected position in which a bearing surface formed on the surgical tool mates with a bearing surface formed on the handle body, and for elongating elastically in response to the connecting force; and

(b) an elongated loading member pivotally connected to the handle body and to the link member for loading and maintaining the connecting force on the link member so that the link member holds the broach in the broaching position.

7. The surgical tool holding apparatus of claim 6 wherein the link member comprises:

(a) an elongated member having an arcuate shape such that a tensile force applied to either end thereof elastically straightens the arcuately shaped elongated member.

8. The surgical tool holding apparatus of claim 6 wherein the handle bearing surface comprises:

(a) at least one pair of opposing bearing surfaces, each surface of the pair lying in a substantially different plane which intersects a longitudinal axis of the handle body at an acute angle, and the planes intersecting to form substantially a v-shape.
