APPARATUS FOR TESTING TIBIAL PROSTHESIS FOR KNEE REPLACEMENT

摘要

The present invention relates to a test apparatus which is coupled to the tibia in advance before implanting a tibial prosthesis used for knee replacement in order to check motility of the tibial prosthesis. More specifically, the test apparatus comprises: a plate test section which is coupled to the tibia; and an insert test section which is detachably coupled to the upper side of the plate test section. The plate test section includes a fixing part, and the insert test section includes a connecting part, wherein the fixing part is formed on one side of the plate test section and is coupled to the connecting part when coupling the plate test section with the insert test section so as to prevent the uncoupling of the plate test section and the insert test section, and the connecting part is formed on one side of the insert test section to press the fixing part so that the plate test section is detachably coupled with the insert test section, whereby the plate test section and the insert test section can be fixedly coupled to each other and the insert test section can be easily replaced. Accordingly, an accurate tibial prosthesis can be selected by accurately measuring the motility of the knee joint, and convenience in use can be improved.
