Problems solved by technology

Due to the poor healing ability of the acromioclavicular ligament and the coracoclavicular ligament, the effect of general conservative treatment is poor, and surgical reconstruction of the coracoclavicular ligament is required
When the coracoclavicular ligament is damaged, the clavicle often shifts, which further increases the difficulty of reconstructive surgery of the coracoclavicular ligament. In the prior art, there is a lack of a method that can reset and fix the clavicle and help reliable drilling. Devices that guide the penetration of reconstruction material

Embodiment approach

[0046] Preferred embodiment: Make a small incision of 2 to 3 cm along the outer edge of the clavicle, and bluntly separate it along the clavicle until the coracoid process; loosen the coracoclavicular ligament to rebuild the locking structure 6 of the positioner, and slowly move the inner rod 1 of the positioner along the incision Push in until the hook 5 reaches the upper edge of the coracoid process; adjust the angle of the inner rod 1 to make the hook 5 go around the coracoid process and hook the lower edge of the coracoid process; push the push-pull button 25 to position the hole on the outer rod 2 The hole is located on the clavicle; the dislocated clavicle is properly reset, the drilling positioning ring 10 is close to the reset clavicle, and the locking structure 6 of the outer rod 2 is locked; the central hole of the drilling positioning ring 10 is 4.5mm The hollow drill drills through the clavicle and coracoid process until it reaches the hook 5; loosen the hollow drill...

Abstract

The invention provides a reconstruction positioning device for a coracoclavicular ligament. The device comprises an inner rod and an outer rod, and the outer rod can slide in the axial direction relative to the inner rod; the inner rod comprises a guiding portion, a resetting portion and a hook, and the guiding portion, the resetting portion and the hook are sequentially arranged in the length extending direction of the inner rod; an included angle is formed by the guiding portion and the resetting portion in the length extending direction, and the guiding portion is embedded into and installed in an axial open hole of the outer rod; the guiding portion and the resetting portion are formed integrally, and the resetting portion and the hook are integrally formed or connected in a fastened mode; a locking structure is arranged on the outer rod and can limit axial relative sliding between the outer rod and the inner rod. The reconstruction positioning device can be applied to resetting and fixing between a coracoid and a clavicle, and guide drilling of a bone tunnel; in addition, the reconstruction positioning device can help penetration of the ligament in the bone tunnel, and guarantees operation convenience and minimally invasive performance.

Description

Technical field [0001] The present invention relates to the field of medical equipment, in particular to a coracoclavicular ligament reconstruction positioning device. Background technique [0002] The coracoclavicular ligament plays a very important role in the stability of the shoulder joint. It maintains the constant relationship between the scapula and the clavicle and ensures the vertical stability of the acromioclavicular joint. Clinically, coracoclavicular ligament injury usually accompanies the acromioclavicular joint ligament injury, mostly caused by the shoulder landing after a fall. Due to the poor healing ability of the acromioclavicular ligament and the coracoclavicular ligament, the effect of conservative treatment is generally poor, and surgery is required to reconstruct the coracoclavicular ligament. Since the coracoclavicular ligament is injured, the clavicle is often displaced, which further increases the difficulty of the reconstruction operation of the coraco...
