Embodiment Construction

[0029] The application will be described in further detail below in conjunction with the accompanying drawings.

[0030] refer to figure 1 , the present application provides a fixation prosthesis for osteolysis treatment, including a fixation plate 1 fitted on the surface of the ilium 13 and a plurality of first fixation screws 3 for fixing the fixation plate 1 on the ilium 13; wherein The fixed plate 1 is customized according to the shape of the surface of the patient's ilium 13 through 3D printing technology. The first fixed screw 3 penetrates the fixed plate 1 and is screwed into the inside of the ilium 13, thereby realizing the adjustment of the position between the fixed plate 1 and the ilium 13. fixed; but due to the impact of osteolysis, the bone marrow in the ilium 13 disappears, and the fixation effect of the first fixation screw 3 is not ideal. In order to make the fixing plate 1 more firmly fixed on the ilium 13, after fixing The surface of the plate 1 close to the...

Abstract

The invention relates to a medical instrument, in particular to an osteolysis treatment fixing prosthesis which is characterized in that the osteolysis treatment fixing prosthesis comprises a fixing plate, a fixing rod and a plurality of fixing screws, the fixing rod extends towards one side of the fixing plate, and a fixing assembly used for fixing the fixing rod to the fixing plate is arranged on the fixing plate; part of the fixing screws are arranged on the fixing plate and used for fixing the position of the fixing plate, and the other part of the fixing screws are arranged on the fixing rod and used for fixing the position of the fixing rod. And the purposes that the multi-point supporting effect on the fixing plate is achieved, and then the stability of the fixing plate is improved are achieved.

Description

technical field [0001] The present application relates to a medical device, in particular to a fixed prosthesis for osteolysis treatment. Background technique [0002] Osteolysis, also known as massive osteolysis, is a rare bone lesion characterized by massive osteolysis; if there are pathological fractures and dysfunction in the lesion, internal fixation, bone cement reconstruction, sham Surgical treatment such as body replacement; when the ilium is pathologically fractured due to osteolysis, a kind of internal fixation described in the related art uses a steel plate, that is, a fixation plate, to be attached to the ilium, and a metal screw, that is, a fixation screw. A plate is fixed to the ilium to connect the broken bones. [0003] In view of the above-mentioned related technical solutions, the inventors found that: the steel plate, that is, the fixed plate has fewer support points, that is, it lacks support at other positions, and in the process of postoperative moveme...
