Abstract

The present invention relates to an annular external fixing stent and fixing device. The annular external fixing stent is used for supporting skeleton and comprises guide rods, fixing rings, sliding units and bone needle assemblies; the sliding units are arranged on the fixing rings and fixedly connected with the guide rods, and mounting positions of the sliding units on radial directions of the fixing rings are adjustable; and the bone needle assemblies are arranged on the fixing rings. Due to the fact that the mounting positions of the sliding units on the radial directions of the fixing rings are adjustable, a total length of the fixing ring and the sliding unit in the radial direction of the fixing ring can be adjusted. When fixing positions of the sliding units on the guide rods are changed at the same time, included angles between the fixing rings and the guide rods can be easily adjusted based on ensuring a simple structure of the annular external fixing stent. When two or morefixing rings are arranged on the guide rods, the included angles between the fixing rings also change to finally meet different support requirements for the skeleton and enhance convenience and application scene applicability of operation of the annular external fixing stent.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an annular external fixation bracket and a fixing device comprising the annular external fixation bracket. Background technique [0002] Ring-shaped external fixation brackets are widely used in orthopedic surgery, which can help the skeleton to reset accurately and heal quickly. Generally, for the traditional ring-shaped external fixation bracket, in order to meet the different support requirements for the skeleton, the two fixing rings are connected by guide rods, and different angles must be formed between the fixing rings. At present, there are structures that realize the adjustable angle. The defects of complex structure. Contents of the invention [0003] Based on this, it is necessary to provide an annular external fixation bracket that realizes adjustable angles between the fixation rings on the basis of a simple structure. [0004] A ring-shaped external ...
