[0001] The invention belongs to the technical field of joint ligament repair, and in particular relates to a positioning guide device for ligament repair and a use method thereof. Background Art

[0002] During the surgical process of repositioning and repairing the acromioclavicular joint and ligaments, a bone tunnel needs to be drilled on the bone across the joint, and then the cable is fixed in the connected tunnel. The steel plate with loops is fixed at both ends of the bone tunnel and tightened by the cable to achieve the repositioning and repair of the acromioclavicular joint. In the process of drilling the bone tunnel, a professional positioning guide device is required for auxiliary positioning, and then a Kirschner wire is used for drilling. However, there is a problem that bothers surgeons during the drilling process, that is, the Kirschner wire needs to penetrate the coracoid process when completing the bone tunnel drilling, and the brachial plexus and subclavian vessels pass through the coracoid process. Drilling too deep has a great risk of damaging the nearby neurovascular system, causing major medical accidents and irreparable damage to patients.

[0003] The existing positioning guide device for acromioclavicular joint reduction ligament repair lacks a setting to prevent excessive drilling, and cannot effectively reduce the risk of surgery. In order to protect the brachial plexus nerve under the coracoid process and the subclavian blood vessels, the soft tissue around the coracoid process is severely damaged during surgical exposure. Therefore, the positioning process of the existing guide device is complicated to operate, and the soft tissue around the acromioclavicular joint is severely damaged. Summary of the invention

[0006] As a further configuration of the above scheme, the concave arc column is an arc-shaped cylinder, the concave arc column and the double-track arc slide rod are arranged correspondingly up and down, a cut-off arc surface is arranged on the inner side of the concave arc column, and Kirschner wire pits are evenly opened on the cut-off arc surface.

[0007] As a further configuration of the above scheme, the positioning tooth is conical, the axis of the positioning tooth coincides with the radial diameter line of the concave arc column, the positioning bent column is an arc-shaped concave column, and the positioning bent column is perpendicular to the concave arc column.

[0008] As a further arrangement of the above scheme, the outer guide cylinder is fixedly connected between the two arc tubes, a sliding hole is opened at the center of the arc tube, the sliding hole is slidably connected to the arc-shaped sliding rod, a middle guide cylinder is arranged in the outer guide cylinder, an inner guide cylinder is arranged in the middle guide cylinder, and a guide needle guide hole is opened on the inner guide cylinder.

[0009] As a further configuration of the above scheme, the guide needle guide hole of the inner guide cylinder always points to the center of or on the line connecting the two ends of the concave arc column after the acromioclavicular joint is reduced.

[0010] A positioning guide device for acromioclavicular joint reduction and ligament repair and a method for using the same, comprising the following contents: firstly, using a C-arm to see through the surgical site to determine the position of the coracoid process and the clavicle coracoclavicular ligament, making an incision of about 3 cm in the upper distal part of the clavicle parallel to the clavicle to expose the clavicle, making an incision of about 2 cm longitudinally from the tip of the coracoid process to the distal side, longitudinally splitting the coracobrachialis and biceps brachii tendons, inserting the lower teeth of the reduction guide device, the positioning bent column and positioning teeth of the lower teeth are placed on the lower edge of the coracoid process bone surface, the concave arc column is located below the coracoid process, and there is a certain gap between the inner arc surface of the concave arc column and the lower edge of the coracoid process bone surface to facilitate the subsequent placement of a ligament repair device, and then placing the upper teeth of the reduction guide device through the clavicle incision, and the double-track arc slide bar is placed above the clavicle.

[0011] Adjust the outer guide cylinder, which slides on the double-track arc-shaped slide rod through the arc-shaped tube to move the Kirschner wire to the specified position. At this time, the central axis of the outer guide cylinder coincides with the central axis of the bone hole to be drilled on the clavicle and coracoid process. The dislocated acromioclavicular joint is clamped by a double-tooth clamp device and fixed by the latch teeth.

[0012] At this time, the outer guide cylinder is fixed, and the inner guide cylinder and the middle guide cylinder are installed. The Kirschner wire is inserted through the guide hole of the inner guide sleeve. When the Kirschner wire is used to drill the clavicle and the coracoid process, since the double-track arc slide bar and the concave arc column are set correspondingly, the Kirschner wire slides with the midpoint of the line connecting the two ends of the concave arc column as the center of the circle, ensuring that the Kirschner wire is smoothly placed in the center of the coracoid process and that the tip of the Kirschner wire is limited to the Kirschner wire pit on the cut-off arc surface.

The plate holder is removed, the tendon line is pulled, and the middle guide cylinder is removed to complete the implantation and fixation of the acromioclavicular joint repair device.

[0014] The present invention has the following beneficial effects: 1. The double-tooth clamp device cooperates with the guide sleeve to smoothly reposition the dislocated acromioclavicular joint. At the same time, the positioning bend column and positioning teeth on the concave arc column can be used to clamp and position the bone surface of the lower end of the coracoid process. The Kirschner wire guide needle can be smoothly inserted into the bone channel through the guide sleeve, which is convenient for surgery.

[0015] 2. The concave arc column and Kirschner wire pit prevent the Kirschner wire guide and drill from drilling too deep, effectively protecting the blood vessels and nerves under the coracoid process.

[0016] 3. The concave arc column design is conducive to reserving space between the bone surfaces at the lower end of the coracoid process, making it convenient for the acromioclavicular joint repair device to be squeezed in and flipped from the outside of the concave arc column.

[0017] The present invention is mainly convenient for the acromioclavicular joint repair surgery. It can not only pressurize and reset the acromioclavicular joint through a double-tooth clamp device, but also guide the installation of an acromioclavicular joint repair device, effectively preventing the nerves and blood vessels under the coracoid process and clavicle from being damaged by Kirschner wires or hollow drill bits, thereby ensuring the safety of the surgery.
