Abstract
The invention relates to a coracoclavicular ligament fixing device for acromioclavicular dislocation and belongs to the field of medical instruments. The coracoclavicular ligament fixing device comprises a carrier, a push rod, pins, an elastic claw and a sleeve, wherein the carrier is connected with the elastic claw through the pins, the detachable push rod is arranged at the center of the carrier, screw holes are arranged at the lower portion of the carrier, and the sleeve is sleeved out of the carrier. The carrier can be pushed forwards when the push rod bears with external force. The elastic claw opens up when the carrier and the elastic claw are pushed out of the sleeve. The coracoclavicular ligament fixing device for the acromioclavicular dislocation is simple in operation, and the sleeve can easily penetrate through bone holes on the coracoid. When opening up, the elastic claw can be firmly hung in the bone holes and can not fall off to lose efficacy when shoulders of a patient move, so that pain caused by reoperation and suffered by the patient is avoided.
Description
Technical field
The present invention is a kind of tough strap retainer that relates to acromioclavicular joint dislocation beak interclavicular ligament processus coracoideus place fixedly the time, belongs to medical instruments field.
Background technology
The processus coracoideus place ligament fixed method fixedly time the for some acromioclavicular joint dislocation beak interclavicular ligaments mainly is to fix through the suspention steel plate clinically, on steel plate, connects prosthetic ligament and realizes that resetting of processus coracoideus and clavicle is fixing.But this method is in operation process; In processus coracoideus bone hole, walk steel plate and the ligament difficulty is very big; And the steel disc of placing is often because of the movable occurrence positions skew of patient's shoulder, and after this horizontal-shift arrived to a certain degree, steel disc can come off from the space in bone hole; Thereby cause acromioclavicular joint to be dislocated once more, the misery that causes the patient to perform the operation once more.
Summary of the invention
The objective of the invention is to: provide a kind of simple to operate, and the holder that can not reset because of the movable processus coracoideus that come off of patient's shoulder and clavicle.
The present invention realizes through following technical scheme: the tough strap retainer at beak interclavicular ligament processus coracoideus place fixedly time during a kind of acromioclavicular joint dislocation comprises carrier, push rod, pin; Elastic claw, sleeve pipe, wherein said carrier links to each other with elastic claw through pin; The center of carrier is provided with a dismountable push rod, and the nail hole is arranged at the bottom of carrier, outside this carrier, is with a sleeve pipe; Carrier can be pushed ahead by external force at push rod as the time spent, when with carrier and elastic claw release sleeve pipe, elastic claw can open.
Said carrier center has a through hole, and through-hole wall has screw thread, and the outer wall of push rod has external screw thread, and this external screw thread and carrier female thread match, and push rod can also can take off from carrier through reverse rotation through the external force rotational fixation in carrier center.
Said elastic claw is that the center of circle is evenly distributed on the carrier with the push rod, and its quantity has four, and the one side that the elastic claw root contacts with carrier has less radian.
Said nail hole has two, and symmetry is positioned at the carrier bottom.
The invention has the advantages that: simple to operate; Sleeve pipe passes the bone hole of processus coracoideus easily; When the elastic claw root has less radian, after being pushed out sleeve pipe, can open automatically by mechanical force, can be suspended on the bone hole from four direction very securely after opening; Just can not cause the inefficacy that comes off of elastic claw because of patient's shoulder activity, the misery of avoiding the patient to perform the operation once more.

The specific embodiment
Acromioclavicular joint dislocation beak interclavicular ligament holder comprises carrier 1, push rod 2, pin 3; Elastic claw 4, sleeve pipe 6, wherein carrier 1 links to each other with elastic claw 4 through pin 3, and there is a through hole at the center of carrier 1; Through-hole wall has screw thread, and the outer wall of push rod 2 has external screw thread, and the female thread of this external screw thread and carrier 1 matches, and push rod 2 can be through the external force rotational fixation at carrier 1 center; Two symmetric nail holes 7 are arranged at the bottom of carrier 1, are used for the prosthetic ligament of contacting, and outside this carrier 1, are with a sleeve pipe 6; After sleeve pipe 6 passed processus coracoideus bone hole, carrier 1 can be pushed ahead by external force at push rod 2 as the time spent, when carrier 1 is released sleeve pipe 6 with elastic claw 4; Four is that the elastic claw 4 that the center of circle is evenly distributed on the carrier 1 can open with the push rod, through reverse rotation push rod 2 is taken off from carrier 1, thereby realizes the fixed effect of acromioclavicular joint dislocation beak interclavicular ligament.
