Problems solved by technology

There are many surgical methods for acromioclavicular joint dislocation. Traditional methods include Kirschner wire tension band fixation and steel wire fixation.
Clavicle hook plate treatment of acromioclavicular joint dislocation, although the effect is good, but these surgical methods are traumatic, heavy soft tissue damage, the hook plate passes through the subacromial, prone to subacromial impingement when the upper limb is abducted, and the price is relatively expensive
In addition, this kind of fixation does not conform to the biomechanical characteristics of the acromioclavicular joint with certain elasticity, so it is necessary to improve the equipment to improve the treatment effect

Embodiment Construction

[0022] Shown in the figure, the present invention is made up of screw 1, nut 2, fastening cable 3, blocking piece 4.

[0023] The front end of the screw 1 is sharp, the middle part has a breaking groove 5, and the rear end is connected with one end of the fastening cable 3. The breaking groove 5 is a continuous groove perpendicular to the axis of the screw and surrounding the circumference of the screw. The bottom of the groove is an acute angle, which is convenient for breaking. The diameter of the screw 1 is 2-5mm, and the nut 2 matches it.

[0024] The fastening cable 3 is a flexible cable, which can be made of high-strength wires such as titanium alloy wire, high-strength ceramic wire, and stainless steel wire. It is selected so that the fastening cable 3 can reach the expected tension level after the nut 2 is tightened. The other end of the fastening cable 3 is connected to the catch 4 .

[0025] The effect of catch piece 4 is to tighten fastening rope 3 on the other s...

Abstract

The invention discloses a flexible fixing device for orthopedics, which belongs to the technical field of orthopedic medicinal apparatuses and elastically fixing orthopedic injuries. The invention adopts the technical scheme that: the device consists of a screw, a nut, a fastening rope and a baffle plate, wherein the front end of the screw is sharp, while the rear end is connected with one end of the fastening rope, and the other end of the fastening rope is connected with the baffle plate; and the diameter of the screw is 3 to 5 millimeters, the nut is matched with the screw, the middle part of the screw is provided with breaking grooves which are continuous grooves surrounding the screw, and the bottoms of the grooves are acute-angled. When the device is adopted, the screw for screwing the nut and the baffle plate are placed on two sides of an inferior tibiofibular joint or an acromioclavicular joint to be fixed, and the middle of the joint is tensioned by the fastening rope to perform flexible fixation. Compared with the traditional rigid fixation, the device has the advantages of low wound, low injury to soft tissues, short operation time, capability of relieving the influence of anesthesia on a patient, short recovery time after the operation, reduction of medicinal load of the patient and the society, simple and convenient operation and convenient popularization.

Description

technical field [0001] The invention relates to a device for bone fixation in the treatment of orthopedic injuries, belonging to the technical field of orthopedic medical devices. Background technique [0002] In the treatment of orthopedic injuries, fixation is an important link, so it has received great attention, and technical improvements are constantly being made in order to achieve better therapeutic effects. In the course of clinical treatment, it was found that the current fixation of inferior tibiofibular separation and shoulder dislocation has certain defects, and it is necessary to improve it. [0003] The inferior tibiofibular joint is composed of three parts: ligament syndesmosis, folds and bony junction. The structure of the inferior tibiofibular joint is both firm and elastic, and it is an important stable structure to ensure the normal movement of the ankle joint. Inferior tibiofibular separation is a common clinical injury, which can lead to instability of ...
