Abstract
An acromioclavicular joint dislocation fixing plate, belonging to the technical field of orthopaedics medical instrument, is used for the repositioning and fixing operation of acromioclavicular joint dislocation. The fixing plate consists of a collarbone positioning sheet, an acromion sheet and a side fork. The collarbone positioning sheet is a rectangle steel, and 2-5 positioning holes are distributed along the longitudinal axis of the sheet. The acromion sheet is a strip steel sheet or titanium plate, the width of the front part is gradually decreasing and the front end is sharp. The rear of the acromion sheet is on one side of the collarbone positioning sheet, and is integrated with the front of the collarbone positioning sheet. The side fork, paralleled with the longitudinal axis of acromion sheet, is connected to the lower part of the side of the acromion sheet, and a gap is provided between the side fork and the acromion sheet. The acromioclavicular joint dislocation fixing plate, when in use, the collarbone positioning sheet is fixed above the collarbone, the side fork is inserted in the central of the cortex on the upper and lower sides of the acromion or below the acromion, and the acromion sheet is fixed on the acromion. The fixing plate has the advantages of large intensity of fixing, well in the operation of ligament prosthesis and the prevention of acromion bumping syndrome, and less harm to capsula articularis acromioclavicularis and the ligament surrounded.
Description
Technical field
This utility model relates to a kind of fixture for the treatment of acromioclavicular joint dislocation, belongs to the orthopedic medical device technical field.
Background technology
In orthopaedic medical treatment operation, the resetting and fixedly be a kind of operation that needs to be grasped of acromioclavicular joint dislocation.Acromioclavicular joint dislocation mostly is the direct violence damage, is subjected to directly clashing into causing injury as shoulder in vehicle accident.When this position fracture or dislocation, near ligament damage in various degree can causing causes the shoulder joint function obstacle.The operation method of treatment acromioclavicular joint dislocation is a lot, traditional has the Kirschner wire tension band to fix, hook plate is fixed, fixation with steel wire etc.In these methods, the shortcoming of Kirschner wire tension band fixing means is that Kirschner wire is deviate from easily, instability before and after fixing not firm causing; And during application hooks steel plate treatment acromioclavicular joint dislocation, the far-end hook of hook plate is inserted in the below of acromion, when the upper limb abduction, produce under the acromion easily and clash into, and, tend to damage ligament of acromioclavicular joint during taking-up because its plate body profile is unfavorable for the reparation of row ligament of acromioclavicular joint more greatly.The far-end of hook plate is inserted under the acromion, and nothing is additionally fixing, so front and back and activity up and down can take place, and part patient's hook plate even generation are obviously dislocated and lost fixation.For this reason, medical worker and patient wish to develop and develop new operating theater instruments and method, so that when the treatment acromioclavicular joint dislocation, reach better surgical effect, can reduce patient's misery and the burden that alleviates economically simultaneously, and can promote the use of at basic hospital.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of carry out that acromioclavicular joint resets and can increase during fixing operation fixing head and acromion constant intensity, be beneficial to capable ligament repair, avoid taking place acromion bump syndrome, when taking out to capsula articularis acromioclavicularis and around the little acromioclavicular joint dislocation fixing head of ligament injury.
The technical scheme that solves the problems of the technologies described above is:
A kind of acromioclavicular joint dislocation fixing head, it is made up of clavicle spacer, acromion sheet, side fork, the clavicle spacer is rectangle steel disc or titanium plate, plate face y direction is distributed with 2-5 locating hole in plate face upper edge, the acromion sheet is rectangular steel disc or titanium plate, its forward width reduces gradually, leading section is sharp-pointed, be fillet or right angle, the rear portion of acromion sheet is positioned at a side of clavicle spacer, links into an integrated entity with clavicle spacer front portion, and the side fork is connected the side-lower of acromion sheet, parallel with the longitudinal axis of acromion sheet, gapped between side fork and the acromion sheet.
Above-mentioned acromioclavicular joint dislocation fixing head, described clavicle spacer are along the Y-direction both sides bending of plate face, and the crooked radian and the periphery of clavicle are complementary.
Above-mentioned acromioclavicular joint dislocation fixing head, there is the crotch of inwardly holding clavicle tightly the both sides of described clavicle spacer.
Above-mentioned acromioclavicular joint dislocation fixing head has the locking screw on the described acromion sheet, and 1-3 locating hole arranged on it.
Above-mentioned acromioclavicular joint dislocation fixing head, described side fork front end is sharp-pointed, and its length is less than or equal to the length of acromion sheet.
Adopt the acromioclavicular joint dislocation fixing head of this structure, the clavicle spacer is fixed on clavicle top during use, and the clavicle sheet outside does not hide the acromioclavicular joint gap, for the reparation of ligament and joint capsule provides the space; The side fork is inserted into the cortex central authorities of acromion upper and lower sides or is positioned under the acromion, use screw the acromion sheet be fixed on the acromion, have constant intensity big, help carrying out repair of ligament, avoid taking place acromion bump syndrome, to capsula articularis acromioclavicularis and around the little advantage of ligament injury.Patient's post-operative recovery time is short, and healing alleviates the medical burden of patient and society smoothly, and technical operation is easy, is convenient to promote at basic hospital.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is a side view of the present utility model;
Fig. 4 is a user mode sketch map of the present utility model.
Labelling is as follows among the figure: clavicle spacer 1, acromion sheet 2, side fork 3, locating hole 4, crotch 5, screw 6, clavicle 7, acromion 8.
The specific embodiment
Fig. 1,2,3 shows, comprises clavicle spacer 1, acromion sheet 2, side fork 3 during this utility model is formed.
Acromion sheet 2 is rectangular steel disc or titanium plate, and its forward width reduces gradually, and leading section is sharp fillet or right angle.The rear portion of acromion sheet 2 is positioned at a side of clavicle spacer 1, links into an integrated entity with clavicle spacer 1 front portion, and common nails hole or screw 6 are arranged on the acromion sheet 2, also screw 6 can be set, only is slick steel disc or titanium plate.Acromion sheet 2 front ends of this spline structure are sharp-pointed and slick and sly, are easy to insert in the epithelial tissue of acromion 8, and acromion sheet 2 width are narrow, when inserting and take out to capsula articularis acromioclavicularis and around ligament injury little.
Fig. 4 is a user mode sketch map of the present utility model.Show among the figure that the clavicle spacer 1 of acromioclavicular joint dislocation fixing head is fixedlyed connected with clavicle 7 by locating hole 4 usefulness screws, the crotch 5 of both sides is held clavicle 7 tightly.The side fork 3 of acromion sheet 2 side-lowers is inserted into the cortex central authorities of acromion 8 upper and lower sides, has so just increased the constant intensity of acromioclavicular joint dislocation fixing head and acromion.The side fork 3 of acromion sheet 2 side-lowers also can be inserted into acromion 8 times, locking screw or common screw 6 can be set on acromion sheet 2, utilize screw that the acromion sheet 2 of acromioclavicular joint dislocation fixing head is fixed on the acromion 8, lock screw is only passed the cortex of acromion 8 tops, and do not pass cortex below it, avoid taking place acromion bump syndrome.As be common screw 6, inserting screw can not be long, avoids damaging shoulder joint, or causes acromion bump syndrome.
