Embodiment Construction

[0013] The coracoclavicular ligament fixer for acromioclavicular joint dislocation includes a carrier 1, a push rod 2, a pin 3, an elastic claw 4, and a sleeve 6, wherein the carrier 1 is connected to the elastic claw 4 through the pin 3, and the center of the carrier 1 has a There are threads on the inner wall of the through hole, and the outer wall of the push rod 2 has external threads. The nail holes 7 are used to connect artificial ligaments in series. The carrier 1 is covered with a sleeve 6. After the sleeve 6 passes through the coracoid bone hole, the carrier 1 can be pushed forward when the push rod 2 is subjected to external force. When the carrier 1 and the elastic claw 4 are pushed out of the sleeve 6, the four elastic claws 4 evenly distributed on the carrier 1 with the push rod as the center of the circle will open, and the push rod 2 will be removed from the carrier 1 by reverse rotation, thereby Achieve the effect of coracoclavicular ligament fixation for acrom...

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 [0001] The invention relates to a ligament fixer at the coracoid process when the coracoclavicular ligament is fixed for acromioclavicular joint dislocation, and belongs to the field of medical instruments. Background technique [0002] For some methods of coracoclavicular ligament fixation for acromioclavicular joint dislocation, the main clinical method is to fix the coracoid process and clavicle through suspension plate fixation, and artificial ligaments are connected to the plate to achieve coracoid process and clavicle fixation. However, in this method, it is very difficult to pass through the steel plate and ligament in the coracoid bone hole during the operation, and the position of the placed steel plate is often shifted due to the patient’s shoulder movement. When the horizontal shift reaches a certain level , The steel sheet will fall off from the gap in the bone hole, which will cause the acromioclavicular joint to dislocate again, causing the pati...
