Abstract

An instrument for inserting a graft fixation device. The fixation device is useful for affixing a tissue graft to a bone or other body surface. The graft fixation device comprises two implantation members connected by a connecting member. The fixation device can be combined with insertion members. The implantation members have longitudinal passageways therethrough. The instrument has a hammer handle slidably mounted to a slide rod. The slide rod is mounted at an angle to a mounting member. A mounting rod having an angulated distal end is mounted to the mounting member. Prongs extend longitudinally out from the angulated distal end. The longitudinal axis of the slide rod is parallel to the longitudinal axis of the angulated distal end. The prongs are optionally removably mounted in an end housing mounted to the angulated distal end.

Claims

1. An instrument for inserting a graft fixation device into bone, said instrument comprising:

a mounting member having a first end, an opposed second end, a top and a bottom;

an elongated slide rod member having a proximal end and a distal end and an outer surface and a longitudinal axis, wherein the distal end of the slide rod is mounted to the first end of the mounting member such that the longitudinal axis of the slide rod is angulated at an acute angle with respect to the mounting member;

a hammer handle member having a distal end, a proximal end, an outer surface, a first flange member extending from the proximal end, a second flange member extending from the distal end, an inner passage therethrough and a longitudinal axis, wherein the hammer handle is slidably mounted to the slide rod member;

a mounting rod having a proximal end and an angulated distal end, wherein the angulated distal end has a longitudinal axis, wherein the proximal end of the mounting rod is mounted to the second end of the mounting member; and

,

a pair of spaced apart prongs extending longitudinally from the distal end of the mounting rod,

wherein the longitudinal axis of the slide rod is parallel to the longitudinal axis of the angulated distal end of the mounting rod.

2. The instrument of claim 1 further comprising an inner shoulder extending into the inner passage of the hammer handle.

3. The instrument of claim 1, wherein the mounting rod additionally comprises a screw threaded distal end, and a housing having an inner cavity and inner screw threads mounted to said threaded distal end, and the prongs extend out from said housing.

4. The instrument of claim 1 wherein the mounting rod is rotatably mounted to the mounting member.

5. The instrument of claim 1 wherein the mounting member has a threaded member mounted thereto at an angle for engaging a first end of a threaded coupling member, and wherein the distal end of the slide member is threaded and engages a second end of the coupling member.

6. The instrument of claim 1 wherein the longitudinal axis of the slide rod is coincident with the longitudinal axis of the angulated distal end.
