A bone resection device for use in resection of bone during joint replacement surgery includes a handle, an elongate shaft rotatably mounted to the handle, a cutting tool housing attached to the shaft at or towards the distal end of the shaft, at least one cutting tool fastened to the housing, and a pivot control member configured to be at least partially disposed about the elongate shaft, the pivot control member being attached at or toward the distal end of the pivot control member to the at least one cutting tool, the distal end of the pivot control member and the distal end of the shaft being configured to be axially displaceable with respect to one another a predetermined distance, during operation of the device.

Bone resection device

A bone resection device () for use in resection of bone during joint replacement surgery includes a rotatable shaft () having mounted thereon for rotation with the shaft at least two blades () carrying at least one cutting edge (). The bone resection device () further includes a blade positioning mechanism () mounted on the device or engaging with the device at least during use thereof and arranged to cooperate with the blades during rotation thereof to alter the orientation of the cutting edge relative to the shaft such that the shape of the resected surface is determined at least in part by the blade positioning mechanism.
