Description

Technical Field

[0001] This utility model relates to a fracture reduction device, specifically a clavicle reduction and fixation device, belonging to the field of fracture reduction devices. Background Technology

[0002] The clavicle, located at the upper front of the thorax, is an important bone connecting the upper limb and trunk. Clavicle dislocation, also known as clavicle fracture, is a common type of fracture. Clavicle fractures are commonly caused by trauma to the lateral shoulder or by trauma transmitted from the upper limb. When a clavicle fracture occurs, timely reduction is necessary. The main methods of clavicle reduction are manual reduction and open surgical reduction. Manual reduction is for fractures without significant displacement or stability. It is generally recommended that the patient try to straighten their chest, fully open the shoulder joint, and then apply a figure-eight bandage to the back for fixation. Surgical reduction includes: 1. Open fracture, severe displacement (shortening > 2 cm or skin protrusion).

[0003] 2. Complications include vascular or nerve damage, multiple fractures, or failure of conservative treatment.

[0004] Surgical reduction methods mainly include: 1. Steel plate screw internal fixation, 2. Intramedullary nailing. Because the clavicle fracture incision is located at the neck-shoulder junction, patients have high aesthetic concerns, and postoperative scarring has a significant impact on their health. Therefore, minimally invasive surgery to minimize surgical scarring is crucial in current treatment. Minimally invasive techniques and good reduction tools greatly aid the procedure. The skin and fascia are then incised sequentially to expose the fracture ends. Temporary fixation with Kirschner wires is first applied, followed by fixation with plates and screws before closing the wound.

[0005] However, when using Kirschner wires for temporary fixation, improper use of the number of Kirschner wires or selection of fixation locations can cause secondary damage to the patient's wound or create additional wounds, thus prolonging the postoperative recovery time. Utility Model Content

[0006] The purpose of this invention is to design a clavicle reduction and fixation device that adopts a modular design to perform targeted reduction and fixation according to the clavicle fracture site, thereby reducing the difficulty of clavicle reduction surgery, reducing surgical wounds, and avoiding secondary damage.

[0007] The technical solution of this utility model is as follows: A clavicle reduction and fixation device includes a clamp body hinged together, the clamp body comprising clamp arms and a clamping part fixedly connected to each other; the clamp arms are divided into a left clamp arm and a right clamp arm, the top of the left clamp arm has a U-shaped notch for mounting a suture reel, the suture reel for holding medical binding sutures; a suture tube is mounted on the outer surface of the left clamp arm for passing the medical binding sutures through; a tube cap is mounted on the upper part of the suture tube; the upper edge of the tube cap has an inverted triangular cut for cutting the medical binding sutures; an embedded needle storage port is also provided on the upper inner side of the left clamp arm, the needle storage port having a built-in magnetic strip; the needle storage port is used to hold a hook needle, which is fixed by the magnetic strip. Securely fasten to prevent falling; the hook needle is used to hook and pull medical sutures; a limit strip is installed in the middle of the inner side of the left clamp arm; the lower inner side of the left clamp arm also has a recessed left mounting groove for installing a rack, the bottom of which is fixed to the edge of the left mounting groove with screws; the outer surface of the right clamp arm is also equipped with a suture tube, and a magnifying glass is also installed at the lower part of the right clamp arm to magnify the wound image for easy observation by the doctor; the lower inner side of the right clamp arm has a right mounting groove, the structure of which is the same as that of the left mounting groove; the right mounting groove is used to install a fixing lock bar, the bottom of which is fixed to the edge of the right mounting groove with screws.

[0010] In addition, the curved teeth and fixed teeth of the clamping part can be replaced with conventional pliers or curved pliers depending on the actual situation.

[0011] Furthermore, the retainer also features a self-locking structure for locking the clamp arms. This self-locking structure consists of a limiting strip, a rack, and a locking bar. The limiting strip has a screw hole at its bottom, which is fixed to the middle of the inner side of the left clamp arm by screws. The limiting strip has a limiting opening at its front, which is used to fit the lower part of the rack to limit its range of motion. The rack has a screw hole at its bottom, which is fixed to the left and right sides of the left mounting slot by screws. The rack has several teeth on its upper part. The upper part of the rack fits into the locking opening of the locking bar. The bottom of the locking bar is installed on the left and right sides of the right mounting slot. The locking bar has a locking opening on its upper part, which is used to lock the teeth of the rack, thereby fixing the left and right clamp arms in place.

[0012] Furthermore, the hook needle is a magnetic metal needle with a triangular barb on one side and a needle handle on the other side.

[0013] The usage method is as follows: 1. Make an incision about 10cm long at the fracture site, then cut the skin and fascia to expose the fracture ends; 2.
