Abstract
A self-locking orthopaedic clamp includes first and second jaws, each jaw having a work engaging surface and a handle comprising first and second actuation members, each actuation member having a first end proximate to the first and second jaws and a second opposed end, and the second actuation member being rigidly coupled to and integral with the second jaw. A four-bar linkage connects the first and second jaws and the first and second actuation members. The design of the clamp and the four-bar linkage is such that the clamp is self-locking. The clamp may be configured for use in a variety of orthopaedic procedures, but it is especially useful for clamping a prosthesis to a resected natural patella.
