Proximal humerus T-shaped outer fixator

Abstract

A proximal humerus T-shaped outer fixator is composed of an outer fixator frame body, a steel needle fixing clamp connected to the outer fixator frame body and a half needle clamped in the steel needle fixing clamp. The outer fixator frame body is composed of a vertical tubular connection rod, a horizontal arc multi-hole connection plate and a locking joint apparatus for connecting the arc multi-hole connection plate to the upper end of the tubular connection rod. The steel needle fixing clamp is composed of a steel needle fixing clamping A connected to the tubular connection rod and a steel needle fixing clamp B connected to the arc multi-hole connection plate. More than three holes are formed in the arc multi-hole connection plate, and the number of the holes is an odd number. The proximal humerus T-shaped outer fixator is simple in structure, stable in fixing, capable of facilitating movement of limbs, suitable for simple fracture and complex fracture in proximal humeral fracture, especially suitable for curing humerus surgical neck fracture, open fracture and infectious fracture and capable of quickly achieving restoration and fixation of the proximal humeral fracture.

Description

technical field [0001] The invention relates to an external fixator for treating fractures of the proximal end of the humerus. Background technique [0002] Proximal humeral fractures are fractures above the base of the greater tuberosity (surgical neck). Both direct shoulder violence and humerus conduction violence can cause proximal humerus fractures. Middle-aged and elderly patients with osteoporosis can cause proximal humerus fractures due to mild or moderate external force. Avulsion fractures and humeral head fractures are often seen when abducted to the ground and upward conduction of external force, which are related to osteoporosis; patients in the prime of life are mostly injured by high-energy direct violence, and most of them are comminuted fractures of the humeral head; children are mostly fractures of the surgical neck. Fracture, followed by slipped epiphysis. [0003] When the proximal humerus is fractured, the deltoid, biceps, long head of triceps, coracobra...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a T-shaped external fixator for the proximal humerus, which solves the problems of the traditional bone fixator for the treatment of humeral fractures, such as complicated and bulky structure, difficult operation, easy restriction of needle penetration, difficulty in fracture reduction, and inconvenience.
