Abstract

The invention discloses a femoral handle fixed through expansion. The femoral handle comprises a femoral handle upper end, a handle body connected with the femoral handle upper end and a handle head connected with the handle body. The handle body is internally provided with an inner handle hole and a screw hole communicated with inner handle hole, the inner handle hole is internally provided with a push rod, the screw hole is internally provided with a screw connected with the push rod, and one end of the screw is provided with an inner square hole. By the femoral handle which is simple in structural design and convenient and rapid to operate, the problem of troubles brought to operation due to the fact that looseness or breaking apart easily occurs to an existing femoral handle during the operation is solved, so that the operation is more successful, success rate of the operation can be improved, and the femoral handle is more practical.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to an expanded and fixed femoral stem. Background technique [0002] The existing femoral stem surgery can only choose from several fixed specifications, and can only choose the femoral stem that is close to the model. It brings a lot of trouble to the operation, and even requires a second operation. This situation can cause great pain to the patient and prolong the postoperative recovery time. Therefore, designing a femoral stem that is simple in structure, convenient and quick to use, and therefore can improve the success rate of the operation has become a problem to be solved in the current industry. Contents of the invention [0003] The object of the present invention is to provide an expanded and fixed femoral stem, which solves the problem that the existing femoral stem is prone to loosening or bursting during operation and brings trouble to the operation. ...
