Problems solved by technology

However, internal fixation products have their unavoidable defects: a second operation is required to remove the internal fixation, the operation requires an incision of the body, causing greater secondary injury to the patient, and the placement of internal fixation devices during incision surgery will also increase the risk of infection. opportunity
Therefore, in recent years, some external fixation products have been seldom used in the treatment of patella fractures at home and abroad, but these external fixation products are not mature enough. appeared, but most of them were gradually eliminated by the market due to the defects in stability and operability

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] see figure 1 and figure 2 , the patella external fixator of the present invention includes a fixator body 1 and several metal bone pins 2, wherein:

[0022] The fixed frame body 1 is in the shape of a part of a hollow spherical shell, which is tightened successively from the bottom to the top surface, that is, the bottom surface and the top surface of the fixed frame body 1 are circular, and each coaxial shaft on the fixed frame body 1 from bottom to top The diameter of the circle decreases gradually; the top surface of the fixed frame body 1 is used as a circular window 11 for observation;

[0023] The fixed mount body 1 of hollow spherical shell shape is provided with a spherical center, and the peripheral surface of fixed mount body 1 is evenly distributed with some threaded holes 12 around the spherical center, and these threaded holes 12 are divided into 2~4 ...

Abstract

The invention discloses a patella external fixing support, which comprises a fixing support main body and a plurality of metal bone needles, wherein the fixing support main body is a partially-hollow spherical housing gradually shrunk from the bottom surface to the top surface and is provided with a spherical center; a plurality of threaded holes are evenly distributed around the spherical center on the circumferential surface of the fixing support main body; the metal bone needles can penetrate through the threaded holes for bolt fixing. The patella external fixing support provided by the invention can externally fix all kinds of patellar fracture in a comprehensive way, has excellent stability, and avoids all sorts of defects of internal fixing.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a patella external fixator. Background technique [0002] For the fixation of patella fractures, most of the fixation forms currently on the market are internal fixation devices, such as tension bands, internal fixation plates, memory alloy patella claws, hollow screws and steel wire binding series. However, internal fixation products have their unavoidable defects: a second operation is required to remove the internal fixation, the operation requires an incision of the body, causing greater secondary injury to the patient, and the placement of internal fixation devices during incision surgery will also increase the risk of infection. Opportunity and so on. Therefore, in recent years, some external fixation products have been seldom used in the treatment of patella fractures at home and abroad, but these external fixation products are not mature enough. There have been many, ...
