Patent Images
1. A tendon approximator including two normally closed clamps, each clamp comprising two connected elements including:
- a base element having a base jaw member, a base handle member and a central, non-circular arcuate cam member;
a clamping element having a clamping jaw member, a clamping handle member and a non-circular arcuate cam-engaging member;
said base element being secured to said clamping element by engagement of at least a portion of said cam-engaging member with said cam member;
said base jaw member and said clamping jaw member having confronting surfaces which are in proximity when said cam-engaging member conforms to the surface of said cam member;
each said clamp having two transverse bores;
a pair of rods fitting in corresponding ones of said bores to support the said two clamps in generally parallel relation;
at least one of said clamps being slideable along the said rods with respect to the other of said clamps.

Abstract
A tendon approximator employs two connected, normally closed clamps, which are each formed from two extruded elements. The two extruded elements are connected together in their mid-region by means of non-circular cam on a base element and a corresponding non-circular cam surface on a clamping element. In the normally closed position of the individual clamps, the cam and cam surface urge the device into a jaw-closed position with the handles being spaced apart. In a preferred embodiment two of the clamps are connected by means of rods extending through corresponding handle portions of the two clamps.
