Abstract

The invention belongs to the field of orthopedic surgery tools, and in particular relates to structure of an infrapatellar fat pad quantitative excision tool. An infrapatellar fat pad excision device comprises a patellar fixator, a locating rod, a ligamentum patellae determination rod and an exsector, wherein the patellar fixator comprises a pair of calipers and a ligamentum patellae fixing rod. With the application of the infrapatellar fat pad excision device, excessive infrapatellar fat pads can be excised to expose an operation field, and meanwhile, dense vascular areas of the infrapatellar fat pads can be effectively reserved, so as to relieve complications which are caused by excising the dense vascular areas together with the infrapatellar fat pads which are excised too much; the excision device is convenient for doctors of joint surgery to operate; and the excision device is conducive to the implementation of a total knee replacement operation.
