Sternum fixer

Abstract

The invention provides a sternum fixer which comprises an upper presser, a lower presser and a connector. The connector comprises a first connector and a second connector, clamping jaws are arranged at opposite far ends of the upper presser and the lower presser which can relatively slide to adjust the distance between the clamping jaw of the upper presser and the clamping jaw of the lower presser, the upper presser and the lower presser are fixedly connected through the first connector, wings are bilaterally and symmetrically arranged on the upper presser and the lower presser, the upper presser and the lower presser relatively slide to drive the wings of the upper presser and the lower presser to correspondingly slide, the distance between the wings of the upper presser and the lower presser is adjusted, through holes are formed in the wings, and a second connector penetrates the through hole, so that the wings are fixed onto a sternum. When the sternum fixer is used for fixing the sternum, more uniform stress is ensured, and the sternum fixer is better in fixing effect.

Description

Technical field [0001] The invention relates to the technical field of medical devices, and in particular to a sternum fixator. Background technique [0002] At present, in treatments that require open thoracotomy, the entire sternum is first incised. At the end of the treatment, the entire sternum is closed and fixed with steel wires. The surgeon uses stitches attached to the steel wires to fix the left and The right cut sternum is tightened with a wire, so that the cut sternum is closed and fixed. [0003] However, with the continuous improvement of the sternum internal fixation system, the traditional stainless steel wire binding and Kirschner wire internal fixation are not only time-consuming, but also the operation is relatively complicated. There is more bleeding during the operation, poor tissue compatibility, and insufficient fixation. The fracture ends have loosening, displacement, breakage, etc., which are gradually replaced by sternum fixators. [0004] The sternum fixat...

AI Technical Summary

Problems solved by technology

[0003] However, with the continuous improvement of the internal fixation system of the sternum, the traditional stainless steel wire binding and Kirschner wire internal fixation are not only time-consuming, but also relatively complicated to operate, with much bleeding during the operation, poor tissue compatibility, unstable fixation and easy The fracture end has disadvantages such as loosening, displacement, and fracture, and is gradually replaced by a sternal fixator

[0004] Sternal fixators currently on the market such as figure 1 As shown, there are many deficiencies and disadvantages: 1) When the postoperative repair requires another thoracotomy, if the fixer cannot be removed and released quickly, it will threaten the life of the patient in serious cases; 2) After the sternum is fixed by the sternum fixer, it can only bear Lateral tension, poor fixation effect; 3) There is also the defect of inconvenient operation during the operation
