Abstract

The invention provides a femoral stem spacer die. A femoral stem includes a femoral stem body, a conehead and a femoral neck; the conehead is arranged at a first end of the femoral stem body and can be matched with a caput femoris; the femoral neck is connected between the conehead and the femoral stem body; the femoral stem spacer die includes two outer dies abutting against each other, each outer die is provided with forming grooves for pouring the femoral stem, the forming grooves include the first forming groove for forming the femoral stem body, the second forming groove for placing the conehead and the third forming groove connected between the first forming groove and the second forming groove, the third forming groove is used for forming the femoral neck, and the second forming groove comprises multiple frustum-shaped grooves matched with the conehead and formed coaxially with the conehead. According to the technical scheme, the problems are effectively solved that in the priorart, products are monotonous in specification, the manufacturing cost is high due to the demand for multiple dies, and dies are inconvenient to use.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a femoral stem spacer mold. Background technique [0002] Deep infection after joint replacement is a serious complication of artificial hip replacement, and its incidence is reported to be 0.5% to 3%. Once infection occurs, it will be a disaster for patients. Chronic infection is the failure of artificial joint replacement. One of the main reasons, its treatment includes the application of antibiotics, debridement, removal of the prosthesis in one-stage surgery and two-stage re-replacement, arthrodesis and amputation, etc. "Second-stage surgery" is currently recognized as the treatment of artificial joint replacement The gold standard for postoperative infection can significantly reduce the reinfection rate of revision surgery, thereby improving the survival rate of the prosthesis. The use of spacers with antibiotics during the interval between two operations can not only rel...
