Abstract
Abstract A modular orthopaedic clamping tool system includes a clamp and a plurality of modular tools. The clamp has a handle having substantially parallel first and second actuation members with a jaw member integral with the first actuation member and a modular attachment element integral with the second actuation member. A linkage connects the first and second actuation members and operates to maintain a substantially parallel orientation between the actuation members while the clamp moves between open and closed positions. In addition, the orthopaedic clamping tool may be locked without causing an excessive clamping force on a clamped bone.

Claim 9
Dependent Claim
50 words
The system of claim 1, wherein a first one of the first and second modular attachment means comprises a wall defining a generally cylindrical bore, and a second one of the first and second modular attachment means comprises a male attachment element sized to mate within the generally cylindrical bore.
