Problems solved by technology

[0004] However, the conventional bone cement spacer of the knee joint is made by hand, and the mold of the existing bone cement spacer of the knee joint is inconvenient to remove, which increases the work difficulty of medical workers. Therefore, how to provide a method for making the bone cement spacer of the knee joint The spacer mold is a technical problem that those skilled in the art need to solve at present

Embodiment Construction

[0041] The following is attached Figure 1-8 The application is described in further detail.

[0042] The embodiment of the present application discloses a knee joint bone cement spacer mold. refer to figure 1 , Figure 5 , a bone cement spacer mold of the knee joint, including a femoral spacer mold 2, a tibial spacer mold 1 and a gap measurement kit used in conjunction with the knee joint infection revision surgery. The spacer mold is obtained by heating and injection molding of polypropylene material, which has high heat resistance and chemical resistance, can be aseptically sterilized, and will not be damaged during the exothermic stage when the bone cement is solidified and shaped. This mold is a one-time use product, even if the mold is slightly deformed when the bone cement is heated, it will not affect it.

[0043] refer to figure 1 , figure 2The tibial spacer mold 1 includes a sleeve 11 , a shaping holder 12 , a shaping cover 13 , a tibial sprue 14 and a tibial ...

Abstract

The present application relates to a knee joint bone cement spacer mold, and relates to the field of bone cement spacer production, which includes a femoral spacer mold and a tibial spacer mold used in knee joint infection revision surgery. This application has the effect of facilitating the production of the knee spacer.

Description

technical field [0001] The present application relates to the field of making bone cement spacers, in particular to a knee joint bone cement spacer mold. Background technique [0002] In bone and joint prosthesis replacement surgery, because of the need to inhibit the rejection of the human body after the prosthesis is implanted, it will relatively reduce the body's resistance to infection. Infections in other parts of the body are also very likely to cause surgical site infection, resulting in surgery fail. The infection site may be due to the growth of bacteria in the biofilm on the surface of the biomaterial of the metal implant. The bacteria are blocked from the body's defense system and antibiotics and cannot be killed. Unless the prosthesis is removed, the infection focus is very Difficult to remove. Therefore, after infection occurs in prosthetic replacement surgery, the prosthesis needs to be removed to completely remove the infection and the joint cavity should be...
