Embodiment Construction

[0016] see figure 1 , a bone cement dry prosthesis prefabricated part for internal fixation, including a thin layer of bone cement 1 that fits the inner wall of the bone marrow cavity 3 at the fracture end, the thickness of the thin layer is 0.1-0.3cm, and the coverage range is the left and right sides of the fracture end. 6-8cm, the degree of solidification of the bone cement is from the late stage of wire drawing to the early stage of dough.

[0017] Such as figure 2 , an internal fixation bone cement dry prosthesis, that is, on the basis of the internal fixation bone cement dry prosthesis prefabricated part, it also includes a bone cement dry 4 filled with the entire bone marrow cavity 3 after the successful internal fixation of the steel plate, the said The length of the bone cement stem 4 exceeds the length of the steel plate used for internal fixation of the fracture. need to figure 2 It should be noted that there is no visible dividing line between the thin layer o...

Abstract

The invention discloses internal-fixation bone cement diaphysis prosthesis, a prefabricated part and a production method of the internal-fixation bone cement diaphysis prosthesis. The internal-fixation bone cement diaphysis prosthesis is characterized by comprising a thin layer of bone cement attached to the inner wall of a marrow cavity at the broken end of fractured bone, the thickness of the thin layer is 0.1-0.3 cm, the cover range is 6-8 cm in the left and right sides of the broken end of fractured bone, and the bone cement curing degree is between the later state of stringiness and the earlier state of dough.

Description

technical field [0001] The invention relates to an internally fixed bone cement dry prosthesis, a prefabricated part and a manufacturing method thereof. Background technique [0002] Bone cement dry prosthesis is an auxiliary device needed for internal fixation of fracture plates, providing sufficient holding force for internal fixation devices (plates, metal nails). The production of dry bone cement prosthesis is a technique often used in orthopedic clinics. But the manufacture method of present bone cement dry prosthesis is to directly pour into bone cement to form bone cement dry, and then nails. At this time, nailing will destroy the stability of the bone cement, and nailing will easily break the bone cement. Therefore need a kind of not destroying the stability of bone cement dry, make the bone cement dry more stable and complete new manufacturing method. Contents of the invention [0003] Aiming at the above shortcomings of the traditional technology, the present ...
