Embodiment Construction

[0025] Examples see Figure 1-3 As shown, this clavicular external fixator with locking joints consists of an external fixator frame, a steel needle clip connected to the external fixator frame, and a threaded half-pin 3 clamped in the steel needle clip.

[0026] The frame body of the external fixator is composed of two threaded connecting rods 1 and a locking joint 2 for hingedly connecting the two threaded connecting rods together. Among the two threaded connecting rods, the one close to the heart is called the inner (near) side threaded connecting rod, and the one away from the heart is called the outer (far) side joint threaded connecting rod. The locking joint 2 is composed of a locking joint A part 4, a locking joint B part 5 and an adjusting bolt 6. One end of the locking joint A part 4 is an internally threaded pipe connected with a threaded connecting rod, and the other end A hinged hole 7 is provided, and one end of the locking joint B part 5 is an internally thread...

Abstract

The invention discloses an outer collarbone fixator with a locking joint, consisting of an outer fixator frame body, a steel needle fixing clamp and threaded half needles, wherein the steel needle fixing clamping is connected to the outer fixator frame body; the threaded half needles are clamped in the steel needle fixing clamp; the outer fixator frame body consists of two threaded connecting rods and the locking joint which is used for hinging and connecting the two threaded connecting rods; the locking joint consists of a locking joint part A, a locking joint part B and an adjusting bolt; one end of the locking joint part A is an internal threaded pipe which is used for connecting with the threaded connecting pipe; a hinge hole is formed in the other end of the locking joint part A; one end of the locking joint part B is an internal threaded pipe which is used for connecting with the threaded connecting rod; a threaded hole is formed in the other end of the locking joint part B; the adjusting bolt passes through the hinge hole in the locking joint part A and is in thread connection with the threaded hole in the locking joint part B. According to the outer collarbone fixator with the locking joint, the structural form that the two threaded connecting rods and the locking joint are used is adopted, the collarbone anatomy and mechanics characteristics are conformed to, and the whole structure conforms to the anatomy requirement of the collarbone better.

Description

technical field [0001] The invention relates to an external fixator for treating clavicle fractures. Background technique [0002] The clavicular bridge is between the sternum and the acromion, and is the only support that connects the shoulder girdle to the trunk. The backbone is thin and curved, and is prone to fractures due to external forces. Clavicle fractures can be divided into transverse fractures, oblique fractures, or comminuted fractures. The incidence of clavicle fractures accounts for about 5% to 10% of systemic fractures. [0003] The clavicle is a long S-shaped tubular bone with a dense honeycomb structure and no obvious medullary cavity. The outer end of the clavicle is curved backward and concave, the inner side is semi-convex to the front, the outer 1 / 3 section is flat, the inner 1 / 3 is approximately triangular, and the middle 1 / 3 is the junction of the inner and outer ends. The smallest, only the subclavian muscle and the thin layer of the pectoralis maj...
