Problems solved by technology

[0005] The length of the existing artificial ligament products is generally 25mm, 30mm, 35mm, etc. If the length of the artificial ligament required by the patient is 33mm, it is impossible to choose a product with a suitable length
[0006] The above prior art or commercially available products all cannot adjust the length of the artificial ligament according to the actual situation of individual patient differences

Embodiment 1

[0049] Such as Figure 1-5 A fixing device for joint dislocation or ligament reconstruction is shown, which includes a cable tie body 1 and a main locking head 2. The cable tie body 1 is in the shape of a long strip, and its length direction includes sequentially connected head sections 11 , the first rack section 12, the coracoid process fitting section 14, the second rack section 16 and the tail section 17, wherein the first rack section 12 and the second rack section 16 form a rack 100 respectively, so The coracoid-fitting segment 14 is wide and flat, and the width of the coracoid-fitting segment 14 is greater than the width of the rest of the coracoclavicular ligament 1;

[0050] The main locking head 2 is flat, and the main locking head 2 is provided with two independent rack passing holes 21 in parallel, and each rack passing hole 21 is provided with a rack one-way buckle 22 , the two rack one-way buckles 22 are reversely set;

[0051] The head section 11 and the tail ...

Embodiment 2

[0055] Same as Example 1, such as Figure 2-10 In the shown fixation device for joint dislocation or ligament reconstruction, ridge teeth 101 are formed on the head section 11 and the tail section 17 respectively;

[0056] The locking head also includes an auxiliary locking head 3, the auxiliary locking head 3 is provided with two independent ridge teeth passing holes 31 in parallel, and each ridge teeth passing hole 31 is provided with a ridge tooth one-way card Buckle 32, the two ridge teeth one-way buckle 32 are reversely set;

[0057] The head section 11 and the tail section 17 respectively pass through the ridge teeth passing holes 31 during the operation, so that the ridge teeth 101 on the head section 11 and the ridge teeth 101 on the tail section 17 are snapped into the corresponding ridge teeth respectively. The one-way buckle 32 of the ridge tooth in the through hole 31 .

[0058] After completing the reconstruction of the coracoclavicular ligament, the redundant s...

Embodiment 3

[0060] All the other are with embodiment 1, as Figure 2-5 and Figure 11 The shown fixation device for joint dislocation or ligament reconstruction, wherein a first ligament simulation segment 13 is provided between the first rack segment 12 and the coracoid process fitting segment 14;

[0061] A second ligament simulation section 15 is provided between the second rack section 16 and the coracoid process fitting section 14;

[0062] The first ligament simulation section 13 and the second ligament simulation section 15 are formed by braiding 3-8 strands of titanium cables. The first ligament simulation section 13 and the second ligament simulation section 15 are designed to be braided with 3-8 strands of titanium cables, and the mechanical effect is better.

Abstract

The invention relates to the technical field of medical apparatuses, in particular to a fixing device for coracoacromial ligament reconstruction, acromioclavicular joint dislocation, knee joint ligament reconstruction, joint dislocation of intra-articular avulsion fracture or ligament reconstruction. The fixing device comprises at least one bandage body and at least one main locking head. The fixing device has the advantages that the length of an artificial ligament can be adjusted according to actual conditions of patients' individual differences, the device not only can be used for the joint dislocation or the ligament reconstruction, but also is suitable for reduction and reconstruction work such as the reduction and reconstruction of the acromioclavicular joint dislocation, the knee joint ligament reconstruction and the reduction and reconstruction of the intra-articular avulsion fracture.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixation device for joint dislocation or ligament reconstruction that can be used for coracoclavicular ligament reconstruction, acromioclavicular joint dislocation, knee joint ligament reconstruction, and intra-articular avulsion fracture. Background technique [0002] The existing coracoclavicular ligament reconstruction, reduction and reconstruction of acromioclavicular joint dislocation, knee ligament reconstruction, and intra-articular avulsion fracture reduction and reconstruction have poor results. [0003] The Chinese invention patent with application number "201610062942.1", application publication number "CN 105640599 A" and title "A device for coracoclavicular ligament reconstruction" discloses a device for coracoclavicular ligament reconstruction, which consists of bone The bone plate is made of titanium alloy, and a circular hole is drilled on the bone plate...
