Abstract
The utility model discloses an acromioclavicular arc-shaped hook plate, which comprises a strip-shaped steel plate; wherein, the strip-shaped steel plate comprises a flat plate; one section of the flat plate is S-shaped; a first hook and a second hook are respectively arranged at the endface and the lateral side at one end of the flat plate; a first slideway slotted hole and a second slideway slotted hole and at least two round holes are arranged in the flat plate; a cancellous bone screw is arranged in the first slideway slotted hole; a cortical bone screw is arranged in the second slideway slotted hole and a round hole; the sharp ends for both the cancellous bone screw and the cortical bone screw are arranged at the same side of the first hook and the second hook. The S-shaped steel plate is matched the upper part of the middle and the remote section in the collar bone, the upper part of the acromioclavicular joint and the outline form of the upper, front, outer and lower part of the acromion; the first hook, the second hook and the cancellous bone screw are fixed with the bone surface for the upper, the front, the outer and the lower part at remote end of the collar bone and the acromion part. The utility model has the advantages of effectively reliably resetting and fixing the acromioclavicular joint fracture dislocation and avoiding loosening of the fracture part and rotation displacement.
Description
Technical field:
This utility model relates to medical apparatus and instruments, relates in particular to the inner fixing device of treatment acromioclavicular joint portion fracture dislocation, particularly treats the nail-plate device of acromioclavicular joint fracture dislocation, and concrete is a kind of shoulder lock arc hook plate.
Background technology:
In the prior art, fixedly clavicle and beak burst method and clavicle hook plate fixing means are treated acromioclavicular joint and are fractured or dislocate to adopt Kirschner wire to intersect fixing means, cancellous bone screw clinically.But above method all exists complication and sequela separately.Kirschner wire easily becomes flexible to be withdrawn into subcutaneous or to enter the interior back migration of soft tissue and enters the thoracic cavity, and the angle of Kirschner wire and articular surface is improper, the fixing insecure inefficacy of easily becoming flexible; And adopt fixedly clavicle processus coracoideus of cancellous bone screw, boring to depart from processus coracoideus easily since around do not have enough grasping forces, the shoulder joint mobility is bigger in addition, it is loosening and make the internal fixation inefficacy that the later stage, internal fixation easily took place, and causes acromioclavicular joint to be dislocated once again; The clavicle hook plate is difficult in the ligament art around the joint capsule repairing fully at the acromioclavicular joint post gap broad that resets, and may dislocate after removing internal fixation again.Defective and deficiency that said method exists make the treatment stability of its fracture or dislocation not good enough, cause that post-operative complication increases, the misery of patient's body and mind and the human body increases.
Summary of the invention:
The purpose of this utility model is to provide a kind of shoulder lock arc hook plate, and described this shoulder lock arc hook plate will solve the technical problem that fixing means treatment stability is not good enough, post-operative complication is many of treatment acromioclavicular joint fracture dislocation in the prior art.
This shoulder lock arc hook plate of the present utility model is made of a strip steel plate, described strip steel plate is made of a flat board, wherein, in the plane of described flat board, dull and stereotyped one section is S-shaped, the end face of a dull and stereotyped end is provided with one first crotch, the side of this dull and stereotyped end is provided with one second crotch, described first crotch and second crotch all are the circular arc bending to the downside of flat board, the axis at the tip of first crotch and second crotch all and dull and stereotyped plane be angle between 160～180 degree, the length of second crotch is greater than the length of first crotch, be provided with one first chute hole and one second chute hole in the flat board, and be provided with two circular holes at least, described first chute hole is positioned at an end at first crotch and the second crotch place, described second chute hole is positioned at dull and stereotyped S shape section, be provided with a cancellous bone screw in first chute hole, be provided with an os integumentale screw in second chute hole and any one the described circular hole, the tip of described cancellous bone screw and os integumentale screw all is positioned at dull and stereotyped downside, the axial cross section of any one circular hole is all V-shaped, and the tail end circumference of cancellous bone screw and os integumentale screw all is coniform.
Further, be provided with interior hex slot in the driving end face of described cancellous bone screw and os integumentale screw.
Further, the transverse diameter of described first chute hole and second chute hole cooperates with the rear end diameter of cancellous bone screw and os integumentale screw.
The fixation principle of laying of the present utility model: in the form fit clavicle of S shape steel plate, section far away top, the acromioclavicular joint top on the acromion, the profile of preceding, outer and below, can press down the clavicle far-end that upwarps of dislocating and also making it to reset after S shape steel plate and clavicle are fixing.First crotch that the orientation angle of steel plate far-end is different and second crotch and cancellous bone screw, with on the acromion portion far-end, preceding, outer, below surface of bone fixes, can realize fixedly securing not exclusively peeling off under the situation that periosteum and muscle adheres to, clavicle far-end fracture gap after second chute hole that is arranged on the nearly section of steel plate can be avoided resetting or the back porch that resets lock joint space are excessive and separate.
This utility model is compared with prior art, and its effect is actively with tangible.This utility model utilizes in the S shape steel plate cooperation clavicle, section far away top, the acromioclavicular joint top, profile on the acromion, below preceding, outer the reaching, utilize on first crotch and second crotch and cancellous bone screw and clavicle, the acromion portion far-end, preceding, outer, below surface of bone fixes, it is fixing reliable after the acromioclavicular joint fracture dislocation is resetted, ligament is repaired in early days around helping acromioclavicular joint, prevent the loosening and rotation displacement of fracture site effectively, can impel the back fracture site that resets to stablize and normally heal with ligament of acromioclavicular joint.
