Embodiment Construction

[0029] Such as figure 1 Shown, be the artificial half pelvis prosthesis of the present invention, it is by being used to be fixed on the fixed seat 1 on the ilium (as Figure 2-4 shown), spherical cup 2 with artificial acetabular function (such as Figure 5-7 shown), used to connect the connecting body 3 of the fixed seat 1 and the spherical cup 2 (such as Figure 8-10 shown) and screw components;

[0030] Connecting body 3 is made up of two plate-shaped connecting arms 4 fixed as a whole, each plate-shaped connecting arm is provided with a bolt through hole 5 matched with the screw, the axes of the two bolt through holes (ie the center Line) angle is 75°-90°; Among the two plate-shaped connecting arms, one of the plate-shaped connecting arms is provided with a bolt through hole on one surface and the other plate-shaped connecting arm is not provided with a bolt through hole. The faces meet and the angle between the two faces is at least 90°;

[0031] The two plate-shaped ...

Abstract

The invention discloses an artificial hemi-pelvic prosthesis which comprises a fixed base and a spherical cup and further comprises a connecting body which is used to connect the fixed base and the spherical cup, and a screwing piece. The connecting body is composed of two plate type connecting arms which are fixed into a whole body. Each plate type connecting arm is provided with a bolt through hole which matches with the screwing piece. The angle between the axes of the two bolt through holes is 75-90 DEG C. The side of one of the plate type connecting arm, which is not provided with a bolt through hole, is connected with the side of the other plate type connecting arm, on which the bolt through hole is arranged, and the angle between the two sides is at least 90 DEG C. The two plate type connecting arms of the connecting body are connected with the fixed base through the bolt through holes respectively by the screwing piece and the spherical cup. The artificial hemi-pelvic prosthesis is simple to assemble and the angle can be adjusted at two approximately perpendicular planes, thus large in flexibility degree. The artificial can satisfy the requirements of operation emergencies, and is convenient to install, and can save time, quicken the process of the operation and make the operation safer.

Description

technical field [0001] The invention relates to an artificial half pelvis prosthesis. Background technique [0002] Pelvic bone tumor is a common disease among pelvic injuries. Pelvic tumors can be divided into primary tumors and metastatic tumors. The former are mainly chondrosarcoma, osteosarcoma, chordoma, and neurogenic tumors, while the latter are commonly seen in bone metastases of breast cancer, kidney cancer, prostate cancer, and lung cancer. The onset of pelvic tumors is insidious and difficult to diagnose in the early stage. When it is discovered, the extent of invasion is often already large. In addition, the anatomy around the pelvis is complex and adjacent to many important organs. The operation is difficult, with many complications, poor curative effect, and high mortality. In the past, hemipelvic resection or modified hemipelvic resection and amputation were mainly used for pelvic tumors, and various pelvic tumor resection and reconstruction operations have ...
