Embodiment 1

[0037] like Figure 1-4 As shown, the titanium cable reconstruction guide for the coracoclavicular ligament includes a titanium cable lead-out part 1 and a titanium cable lead-in part 2. The titanium cable lead-in part 2 is provided with an introduction channel 3 for the titanium cable 23 to be introduced, and the titanium cable lead-out part 1 is provided with a There is a lead-out channel 4 for the titanium cable 23 to lead out, and one end of the titanium cable lead-out part 1 is a wrapping part 7 that can wrap around the coracoid process 5, and there is a connection between the wrapping part 7 and the titanium cable lead-in part 2, which can be connected and introduced. The communication and positioning structure of channel 3 and lead-out channel 4. The titanium cable exporting part 1 and the titanium cable introducing part 2 are combined to form a reconstructor for the introduction of the titanium cable 23. The reconstructor does not need to incise the tissue for internal...

Embodiment 2

[0042] like Figure 4-9 As shown, the method for reconstructing the coracoclavicular ligament with the titanium cable without perforation using the reconstruction guide in Example 1 includes the following steps:

[0043] a1. Wrap the wrapping part 7 of the titanium cable lead-out part 1 around the coracoid process 5 in the front and bottom direction of the clavicle 6, and then initially reset the acromioclavicular joint;

[0044] a2. Push the titanium pull-in part 2 along the positioning seat 16, and insert the titanium pull-in part 2 into the socket 9 of the titanium pull-out part 1;

[0045] a3. Insert the titanium cable 23 into the lead-in channel 3 of the titanium cable lead-in part 2, and continue to push the titanium cable 23 until the titanium cable 23 passes through the lead-out channel 4 of the titanium cable lead-out part 1 from the titanium cable lead-out part 1;

[0046] a4. Remove the titanium cable lead-in part 2 and the titanium cable lead-out part 1. At this t...

Embodiment 3

[0048] The method for perforating and reconstructing the coracoclavicular ligament with the reconstruction guide in Example 1 comprises the following steps:

[0049] b1. Place the wrapping part 7 of the titanium cable exporting part 1 on the lower part of the coracoid process 5, and initially reset the acromioclavicular joint;

[0050] b2. Push the titanium cable introduction part 2 along the positioning seat 16 to form a tunnel on the clavicle 6 and the coracoid process 5. The titanium cable introduction part 2 passes through the tunnel opened on the clavicle 6 and the coracoid process 5, and then inserts it into the In the jack 9 of the cable outlet 1;

[0051] b3. Insert the titanium cable 23 into the introduction channel 3 of the titanium cable introduction part 2, and continue to push the titanium cable 23 until the titanium cable 23 passes through the titanium cable export part 1 through the export channel 4 of the titanium cable export part 1;

[0052] b4. Remove the t...

Abstract

The invention belongs to the technical field of medical equipment, and especially relates to a coracoclavicular ligament titanium cable reconstruction guider and a reconstruction method for a coracoclavicular ligament. The coracoclavicular ligament titanium cable reconstruction guider comprises a titanium cable guiding out component and a titanium cable guiding in component. The titanium cable guiding in component is internally provided with a guiding-in channel used for guiding a titanium cable in. The titanium cable guiding out component is provided with a guiding-out channel used for guiding the titanium cable out. One end of the titanium cable guiding out component is a wrapping portion which can wrap a coracoid. A communication positioning structure which can communicate the guiding-in channel with the guiding-out channel is arranged between the wrapping portion and the titanium cable guiding in component. The coracoclavicular ligament titanium cable reconstruction guider is advantaged in that the titanium cable guiding out component and the titanium cable guiding in component combine to form a reconstruction device for the titanium cable to guide in. The reconstruction device does not need to cut open a tissue to internally fix coracoid clavicles, to prevent damages on the coracoid, clavicles, and peripheral tissues of both, and save large amount of operation time. Thus, security of an operation is improved, and fixation stability is enhanced by using titanium cable two-beam fixation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a coracoclavicular ligament titanium cable reconstruction guide and a coracoclavicular ligament reconstruction method. Background technique [0002] As we all know, the coracoclavicular ligament plays a very important role in the stability of the acromioclavicular joint. It maintains a constant relationship between the scapula and the clavicle, and ensures the stability of the acromioclavicular joint in the horizontal direction. 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. The patent document [CN201510195516.0] discloses a guiding device for coracoclavicular ligament reconstruction, which includes a guiding plate, a guiding tube, a positioning rod and a coracoid posit...
