Embodiment 1

[0018] Such as figure 1 The plate-shaped bone plate is used to reconstruct the state of the coracoclavicular ligament. It consists of 2 plate-shaped bone plates, 1 strip-shaped bone plate, and high-strength sutures. The parallel bone plate is made of titanium alloy, and its two ends are drilled with round holes hole; the high-strength suture is made of polyethylene terephthalate material; the high-strength suture is used in conjunction with the bone plate; when in use, a small incision of 3.0 cm is taken above the distal clavicle and placed on the coracoclavicular ligament A drill with a diameter of 4.5 mm was used to establish two bone medullary canals at the insertion point of the clavicle, and a bone tunnel was established on the coracoid process. Two single-strand No. 5 high-strength sutures (Arthrex Company, the United States) were passed through the two round holes in the middle section of the mini-strip bone plate. Adjust the position of the bone plate with the guide w...

Embodiment 2

[0021] Such as figure 2 The combination of flat plate and curved bone plate is used to reconstruct the state of the coracoclavicular ligament. It consists of a flat plate and a curved bone plate, and No. 5 polyethylene terephthalate sutures. The curved bone plate is made of titanium alloy, and the two bone plates are drilled with circular holes; the flexible fixation rope is made of polyethylene terephthalate; the flexible fixation rope is used in conjunction with the bone plate; , Take a 1.5cm small incision above the distal clavicle, use a drill with a diameter of 4.5mm to establish a bone tunnel at the clavicle insertion of the coracoclavicular ligament, and create a tunnel on the coracoid process. A single-strand No. 5 high-strength suture (Arthrex Company, USA) was passed through the two round holes in the middle section of the mini-strip bone plate. Adjust the position of the bone plate, pull up the suture at both ends, reset the acromioclavicular joint under the direc...

Abstract

The invention provides a device for reconstructing the coracoclavicular ligament. The device is composed of a bone fracture plate and high strength sutures, and the bone fracture plate is made of a titanium alloy material and provided with drill holes; the high strength sutures are made of a polyethylene terephthalate material; the sutures and the bone fracture plate are used in a matched mode; when the device is used, after the clavicle resets, the bone fracture plate is placed on the attachment segment of the clavicle coracoclavicular ligament, holes are drilled in two bones respectively, the high strength sutures sequentially penetrate through a hole channel in the bone fracture plate and holes drilled in the two bones to fix the clavicle onto a coracoids, then a flexible fixing rope is tightened till the clavicle and the coracoids recover to the normal distance, and finally knotting is conducted to conduct fixation. According to the device, in treatment of acromioclavicular dislocation, the problem of coracoclavicular ligament reconstruction is solved, and an internal fixator is removed without secondary surgery; the problem of ligament repair is solved, and pain of self-lifted ligament reconstruction is avoided; the device and an operation mode are minimally invasive, postoperative recovery is high in speed, pain of a patient is reduced, and the device is applicable to acromioclavicular dislocation caused by shoulder joint surgical treatment trauma and the like.

Description

technical field [0001] The invention relates to a medical device, in particular, it belongs to a device for elastic reconstruction of coracoclavicular ligament. Background technique [0002] As we all know, the coracoclavicular ligament plays a very important role in the stability of the shoulder joint. It maintains the constant relationship between the scapula and the clavicle, and ensures the stability of the acromioclavicular joint in the vertical direction. [0003] Acromioclavicular joint dislocation is a common disease in shoulder surgery. At present, open reduction and internal fixation and ligament reconstruction are the main methods for the treatment of severe acromioclavicular joint dislocation, which mainly include needle fixation through the acromioclavicular joint, coracoclavicular screw fixation, hook plate fixation, and ligament reconstruction. However, postoperative complications such as failure of reduction and shoulder joint pain are not uncommon, and seco...
