Embodiment Construction

[0020] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a combined shoulder joint spacer mold is composed of three parts: a spherical body 1 in the upper part, a main body 2 in the lower part and a metal support rod 3 in the middle part. The ball body and the main body can be assembled into a whole mold through the slot 4 . Before the mold is assembled, a metal support rod 3 can be placed in the middle of the mold to enhance the strength of the manufactured antibiotic bone cement handle 8 . The ball head 1 and the main body 2 have various types and sizes respectively, and the ball head 1 and the main body 2 of different models and sizes can be matched and combined with each other, so that more suitable molds can be produced without too many molds. Type and size of antibiotic cemented stems. In use, assemble the combined shoulder joint spacer mold, insert the muzzle 6 of the bone cement gun 5 into the injection port 7 of the combined shoulder joint spacer mold...

Abstract

The invention discloses a combined shoulder joint spacer die which is composed of a ball body on the upper portion, a main body on the lower portion and a metal supporting rod in the middle. The ball body and the main body are assembled to form a whole die through clamping grooves. After the metal supporting rod is placed in the die, the die can be used as the shoulder joint spacer die to make antibiotic bone cement prosthesis placeholder handles on the infected portions during shoulder joint prosthesis replacement surgeries. The combined shoulder joint spacer die is designed to conduct sterilization after washing; is disposable, thus ensuring product safety. The combined shoulder joint spacer die adopts medical silicone rubber with appropriate hardness for raw materials, thus being capable of ensuring bone cement forming accuracy.

Description

technical field [0001] The invention relates to a disposable combined shoulder joint prosthesis spacer mold, which is suitable for making antibiotic bone cement prosthesis handles for infected parts in shoulder joint prosthesis replacement operations. It is characterized by safety, reliability, easy operation, flexible combination of ball head and main body. After bone cement injection, the shape is perfect. Metal support rods can be inserted to increase the strength of the formed cement spacer. Background technique [0002] Surgical implant arthroplasty has been around for quite a long time. During shoulder prosthesis replacement, pre-infection of the implant site will always be encountered. Combined shoulder spacer mold is a prosthesis for pre-replacement in shoulder joint replacement surgery. [0003] The principle is that, for shoulder joints with viral or bacterial lesions, it is not suitable to directly implant prosthetic joints. Usually, the inflammation should be...
