Abstract: The present invention provides a supporting hook structure, comprising a sleeve, a fixing rod, a first limit unit, a hook and a fixing device. The fixing rod is connected to the side surface of the sleeve. The hook body is connected to one end of the sleeve. The first limit unit is arranged on the side surface of the sleeve and adjacent to the hook body. The first limit unit makes the hook body rotates with the axis direction of the sleeve as a rotation axis. The fixing device is connected to the other end of the sleeve to fix the rotating position of the hook body. Through the above, the hook part enters the proximal thigh from a surgical entrance and the hook part rotates to make the hook part abut against the proximal femur to complete the positioning and fixation of the femur hook structure to the femur.

Abstract: A femoral lift apparatus includes a lift device and a hook device. The hook device is coupled to the lift device. The femoral lift apparatus is labor-saving and can avoid the problem that the conventional femoral lift apparatus may block the surgical view, hinder the operation position for a hip joint replacement surgery. With the assistance of this current femoral lift apparatus, the hip joint replacement surgery can be performed more smoothly.

Abstract: An implant guide system for hip replacement surgery includes an angle guide member and a first positioning plate. The angle guide member has a body and a protrusion that are substantially connected to each other. The body has a curved surface corresponding in shape to a surface of a patient's acetabulum. The protrusion has a first through hole extending to the body. An acute angle is defined between an extension line of the first through hole and a flat surface of the body. The first positioning plate has a first holding portion and a first spacing portion that are substantially connected to each other. The first spacing portion has a second through hole, a third through hole and a fourth through hole that are parallel to each other.

Abstract: A structure improvement of orthopaedic implant for connecting a distal femur and a proximal tibia, and a stem was implanted into the proximal tibia, in which formed to allow inter-engagement between the stem of the tibia and the structure improvement of orthopaedic implant. The structure improvement of orthopaedic implant includes a tibial baseplate, a tibial insert, and a reinforcement. The tibial baseplate forms a recess having a bottom that has a central portion defining a through hole extending through the tibial baseplate. The tibial insert includes a support, a through region, and a projection, wherein an end of the tibial insert forming the projection corresponding to the recess of the tibial baseplate for press-fitting to the tibial baseplate. The reinforcement is inset in the tibial insert and includes a sleeve and a bolt. As such, the advantages of stable coupling includes force resistance, avoids insert loosening then extends prosthetic longevity.

Abstract: A structure improvement of orthopaedic implant includes a tibial baseplate, a tibial insert, and a reinforcement. The tibial baseplate forms a recess having a bottom that has a central portion defining a through hole extending through the tibial baseplate. The through hole has a top circumference that defines a circumferential groove extending outward. The tibial insert has a bottom forming a projection corresponding to the recess of the tibial baseplate for press-fitting to the tibial baseplate. A support is formed on at a central portion of a top of the tibial insert and defines a bore that extends through the tibial insert. The tibial insert forms two curved surfaces on opposite sides of the support to support contact and rolling. The reinforcement is inset in the tibial insert and includes a sleeve and a bolt.
