Embodiment 1

[0033] Such as figure 1 , 2 A coracoclavicular ligament reconstruction device shown includes a first button plate 1, a second button plate 2, an artificial ligament 3 and a bone-attached plate 4, wherein:

[0034] The first button steel plate 1 and the second button steel plate 2 are both oval plate-shaped structures, and the first button steel plate 1 and the second button steel plate 2 are respectively provided with four limit holes, and the artificial ligament 3 is rooted during the operation. The actual situation of the patient selects and passes through the limiting holes of the first button plate 1 and the second button plate 2;

[0035] The bone-attached steel plate 4 is composed of a left steel plate 401 and a right steel plate 402, both of which are "U" shaped. The opening ends of the left steel plate 401 and the right steel plate 402 are connected by mortise and tenon. The steel plate 402 makes the upper part of the bone-attached steel plate 4 form a groove 41 adap...

Embodiment 2

[0041] Such as image 3 A coracoclavicular ligament reconstruction device shown includes a first button plate 1, a second button plate 2, an artificial ligament 3 and a bone-attached plate 4, wherein:

[0042] The first button steel plate 1 and the second button steel plate 2 are both plate-like structures, and at least two limiting holes are set on the first button steel plate 1 and the second button steel plate 2 respectively, and the artificial ligament 3 passes through the second button steel plate during operation. In the limiting holes of the first button steel plate 1 and the second button steel plate 2;

[0043] The bone-attached steel plate 4 is inserted between the first button plate 1 and the second button plate 2 during operation. The bone-attached steel plate 4 is horseshoe-shaped.

[0044] The lower surface of the bone-bonded steel plate 4 is in a concave shape matching the shape of the clavicle, and the lower surface of the bone-bonded steel plate 3 is a burr ...

Embodiment 3

[0049] All the other are with embodiment 2, as Figure 4 A coracoclavicular ligament reconstruction device shown, wherein one side of the opening end of the bone-attached steel plate 4 is hinged to one end of a stopper 5, and the other end of the stopper 5 is connected to the other end of the open end of the bone-attached steel plate 4. side activity connection. The limit bolt 5 can further limit the position of the bone-attached steel plate.

Abstract

The invention relates to the technical field of medical apparatus and instruments, and in particular relates to a coracoclavicular ligament reconstruction device. The coracoclavicular ligament reconstruction device comprises a first button steel plate, a second button steel plate, an artificial ligament and a bone-attaching steel plate, wherein the first button steel plate and the second button steel plate are of plate-shaped structures, at least two limiting holes are formed in each of the first button steel plate and the second button steel plate, and the artificial ligament passes through the limiting holes of the first button steel plate and the second button steel plate during matched use. The coracoclavicular ligament reconstruction device has the beneficial effects that the device belongs to a joint dislocation or ligament reconstruction fixing device capable of realizing the adjustment on the length of the artificial ligament according to the practical conditions of the individual differences of patients, and the coracoclavicular ligament reconstruction device can play the fixing role in joint dislocation or ligament reconstruction, and is also applicable to the restoration and reconstruction including acromioclavicular joint dislocation restoration and reconstruction, knee-joint ligament reconstruction, intra-articular avulsion fracture restoration and reconstruction and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a coracoclavicular ligament reconstruction device. Background technique [0002] The existing coracoclavicular ligament reconstruction, reduction and fixation are not effective. [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; the high-strength suture is made of polyethylene terephthalate; the high-strength suture and the bone When in use, make a small incision above the distal end of the clavicle, drill the medullary canal at the clavicle insertion of the coracoclavicular ligament, and build a tunnel on the coracoid process; pass high-strength sutures...
