Abstract
本发明涉及一种肩锁关节脱位喙锁间韧带固定器，属于医疗器械领域。本发明包括载体，推杆，销子，弹性爪，套管，其中所述载体通过销子同弹性爪相连，载体的中心设有一根可拆卸的推杆，载体的下部有钉孔，在此载体外套有一套管，载体可在推杆受外力作用时向前推进，当将载体和弹性爪推出套管时，弹性爪会张开。本实用新型操作简单，套管容易穿过喙突上的骨孔，当弹性爪张开后可以很牢固吊在骨孔上，不会因为患者的肩部活动导致弹性爪的脱落失效，避免患者再次手术的痛苦。
The invention relates to a coracoclavicular ligament fixer for acromioclavicular joint dislocation, which belongs to the field of medical instruments. The present invention includes a carrier, a push rod, a pin, an elastic claw, and a sleeve, wherein the carrier is connected with the elastic claw through a pin, a detachable push rod is arranged in the center of the carrier, and a nail hole is provided in the lower part of the carrier. The outer casing of the carrier has a sleeve, and the carrier can be pushed forward when the push rod is subjected to external force. When the carrier and the elastic claws are pushed out of the sleeve, the elastic claws will open. The utility model is easy to operate, and the casing can easily pass through the bone hole on the coracoid process. When the elastic claw is opened, it can be hung on the bone hole firmly, and the elastic claw will not fall off due to the patient's shoulder movement, preventing the patient from The pain of reoperation.
Description
Technical field
The present invention is a kind of tough strap retainer relating to processus coracoideus place when acromioclavicular joint dislocation beak interclavicular ligament is fixed, and belongs to medical instruments field.
Background technology
The method that when fixing for some acromioclavicular joint dislocation beak interclavicular ligaments, processus coracoideus place ligament is fixing, clinically mainly by suspention Interal fixation, steel plate connects prosthetic ligament to realize the replacement and fixation of processus coracoideus and clavicle.But this method is in operation process, steel plate is walked and ligament difficulty is very large in processus coracoideus bone hole, and the steel disc placed is often because there is position skew in the shoulder activity of patient, when this horizontal-shift arrives to a certain degree, steel disc can come off from the space of bone hole, thus cause acromioclavicular joint Redislocation, cause the misery that patient performs the operation again.
Summary of the invention
The object of the invention is to: provide a kind of simple to operate, and the holder that the processus coracoideus that can not come off because the shoulder of patient is movable and clavicle reset.
The present invention is achieved through the following technical solutions: the tough strap retainer at processus coracoideus place when beak interclavicular ligament is fixed during a kind of acromioclavicular joint dislocation, comprises carrier, push rod, pin, elastic claw, sleeve pipe, wherein said carrier is connected with elastic claw by pin, the center of carrier is provided with a dismountable push rod, nail is arranged at the bottom of carrier, has a sleeve pipe at this carrier overcoat, and carrier can be pushed ahead by during External Force Acting at push rod, when carrier and elastic claw are released sleeve pipe, elastic claw can open.
Described carrier center has a through hole, and through-hole wall has screw thread, and the outer wall of push rod is with external screw thread, and this external screw thread matches with carrier female thread, and push rod rotates by external force and is fixed on carrier center, also takes off from carrier by reversely rotating.
Described elastic claw is that the center of circle is evenly distributed on carrier with push rod, and its quantity has four, and the one side of elastic claw root and carrier contact has less radian.
Described nail has two, and symmetry is positioned at carrier bottom.
The invention has the advantages that: simple to operate, sleeve pipe is easily through the bone hole of processus coracoideus, when elastic claw root has less radian, automatically can open by mechanical force after being pushed out sleeve pipe, can be suspended in bone hole from four direction very securely after opening, the inefficacy that comes off of elastic claw would not be caused because of the shoulder activity of patient, avoid the misery that patient performs the operation again.

Detailed description of the invention
Acromioclavicular joint dislocation beak interclavicular ligament holder, comprise carrier 1, push rod 2, pin 3, elastic claw 4, sleeve pipe 6, wherein carrier 1 is connected with elastic claw 4 by pin 3, there is a through hole at the center of carrier 1, through-hole wall has screw thread, the outer wall of push rod 2 is with external screw thread, this external screw thread matches with the female thread of carrier 1, push rod 2 rotates by external force and is fixed on carrier 1 center, two symmetrical nail 7 are arranged at the bottom of carrier 1, be used for contact prosthetic ligament, a sleeve pipe 6 is had at this carrier 1 overcoat, when sleeve pipe 6 is through after processus coracoideus bone hole, carrier 1 can be pushed ahead by during External Force Acting at push rod 2, when carrier 1 and elastic claw 4 are released sleeve pipe 6, four is that the elastic claw 4 that the center of circle is evenly distributed on the carrier 1 can open with push rod, by reversely rotating, push rod 2 is taken off from carrier 1, thus realize the fixing effect of acromioclavicular joint dislocation beak interclavicular ligament.
