Abstract
The utility model discloses an acromioclavicular joint fixing apparatus which comprises a steel plate, wherein the steel plate comprises an acromion part and a clavicle part; one side of the acromion part and one side of the clavicle part are located on the same straight line; the width of the acromion part is larger than that of the clavicle part; a long strip-shaped groove is formed in the middle of the acromion part; acromion screws are connected with two parts of the long strip-shaped groove respectively; a threaded hole is formed in the middle of the clavicle part; a clavicle screw is connected onto the threaded hole; an axis of the clavicle screw is separated from the plane where the two acromion screws are located; and each acromion screw comprises an upper acromion screw part, a connecting pole and a lower acromion screw part, the width of the connecting pole is larger than that of the long strip-shaped groove, and self-tapping threads are formed at the lower acromion screw. The treatment time of the acromioclavicular joint fixing apparatus is the same as that of external fixation and is obviously shorter than that of operative treatment, the dislocated acromioclavicular joint can be firmly fixed after reduction, and functions of the shoulder joint are not influenced; and the acromioclavicular joint fixing apparatus has the advantages of small trauma and unobvious operative scar.
Description
Technical field
This utility model relates to a kind of acromioclavicular immobilizer, belongs to mechanical field.
Background technology
At present, treatment acromioclavicular joint dislocation or the conventional method of subluxation have two kinds: the one, by the capable Gypsum Fibrosum of closed reduction outward fixing or neck wrist suspender belt fix, fixedly securing after this method can not make the acromioclavicular joint of dislocation be resetted conventionally, has impact in various degree to shoulder joint function; The 2nd, by fixing in open reduction Cross K-wire, shortcoming is to need second operation to take out inside-fixture, and wound that patient is caused is large, operative scar is obvious.
In addition, also have a kind of method of not promoting clinically, its patent No. is: " 982226179 ", and the shortcoming of this technology is: the locations of structures of device is unreasonable, causes the inconvenience of wearing the clothes; Fixing unstable, scapula screw easily occurs loosening
.
Utility model content
The technical problems to be solved in the utility model is for above deficiency, and a kind of acromioclavicular joint fixedly securing after being resetted that can make dislocation is provided, and does not affect shoulder joint function, and wound is little, the unconspicuous acromioclavicular immobilizer of operative scar.
For solving above technical problem, this utility model is by the following technical solutions: a kind of acromioclavicular immobilizer, comprise steel plate, and described steel plate comprises acromion portion and clavicle portion, one side of described acromion portion and clavicle portion is on same straight line, and the width of described acromion portion is greater than the width of clavicle portion;
Described acromion portion centre is provided with rectangular groove, described rectangular groove two parts are not connected with acromion screw, the middle of described clavicle portion is provided with screwed hole, is connected with clavicle screw on described screwed hole, the axis of described clavicle screw and two acromion screw place planes from;
Described acromion screw comprises acromion screw top, joint pin and acromion screw bottom, and the width of described joint pin is greater than the width of rectangular groove, and described acromion screw bottom is provided with tapping screw thread.
A prioritization scheme, the diameter of described acromion screw and clavicle screw is respectively 2.5mm.
Further, the corner of described steel plate is circular arc.
Further, described acromion screw, clavicle screw and steel plate adopt respectively nut to be fixed.
This utility model has the following advantages compared to prior art:
This utility model is applicable to 1,2 degree acromioclavicular joint dislocation, and 3 degree dislocations can the proper extension set time, and treatment time of the present utility model is fixed equally with outer, is obviously less than operative treatment; Acromioclavicular joint the fixedly securing after being resetted that can make dislocation, does not affect shoulder joint function; There is wound little, the unconspicuous advantage of operative scar.
This utility model patent No. of comparing is: the technology of " 982226179 " has the following advantages: rational in infrastructure, wear the clothes conveniently; The design of employing square body, can prevent from being threaded in shoulder joint excessively dark; Adopt two acromion screws to be fixed, make fixedly, there will not be loosening.
This utility model adopts the screw designs of 2.5mm, is because acromion area is less, does not hold too thick screw, and uses thicker screw easily to cause that external fixer is excessive, is inconvenient to wear the clothes; The easily fracture of words that screw is thin.
Below in conjunction with drawings and Examples, this utility model is elaborated.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of acromioclavicular immobilizer in this utility model embodiment;
