Fig. 2 is according to the top view embodiment of the present invention, shoulder joint fixing head.
Fig. 3 is according to the upward view embodiment of the present invention, shoulder joint fixing head.
Fig. 4 is according to the using state figure embodiment of the present invention, shoulder joint fixing head.
In figure, labelling is as follows: acromioclavicular joint spacer 1, acromion sheet 2, side fork 3, locating hole 4, crotch 5, locating hole 6, clavicle 7, acromion 8, abutment sleeve 9, acromion sleeve 10, connecting rod 11.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Fig. 1,2,3 demonstrations, the present invention forms and comprises acromioclavicular joint spacer 1, acromion sheet 2, side fork 3, abutment sleeve 9, acromion sleeve 10, connecting rod 11.
Acromioclavicular joint spacer 1 is rectangle steel disc or titanium plate, and along Y-direction two lateral bends of plate face, crooked radian and the periphery of clavicle 7 match.On plate face, along plate face y direction, be distributed with 6 locating holes 4, there is the crotch 5 of inwardly holding clavicle 7 tightly the both sides of plate face, and crotch 5 can not wanted yet.
Acromion sheet 2 is rectangular steel disc or titanium plate, and its anterior width reduces gradually, and leading section is sharp fillet or right angle.Acromion sheet is straight plate or along X direction two lateral bends of plate face, wherein outside, bending place accounts for the 2/3-3/4 of acromion sheet length, and flexibility is 20 °-30 °.On acromion sheet 2, having common nails hole or screw 6, also screw 6 can be set, is only smooth steel disc or titanium plate.Acromion sheet 2 front ends of this spline structure are sharp-pointed and round and smooth, 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 is little.
Acromioclavicular joint spacer 1 and acromion sheet 2 adopt and are flexibly connected.In the front portion of acromioclavicular joint spacer 1 bottom surface, be fixed with 4 abutment sleeves 9, in abutment sleeve 9, have screw thread.There is acromion sleeve 10 rear in acromion sheet 2 bottom surfaces, and acromion sleeve 10 is through hole, and its position is corresponding with abutment sleeve 9.In acromion sleeve 10, have connecting rod 11, the front end of connecting rod 11 has screw thread.Connecting rod 11 screws in abutment sleeve 9 through acromion sleeve 10.There is cylindrical pole cap the rear end of connecting rod 11, and pole cap is positioned at the outer end of acromion sleeve 10, and the diameter of pole cap is greater than the internal diameter of acromion sleeve 10, can make connecting rod 11 can not deviate from.
Acromioclavicular joint spacer 1 side-lower connects side fork 3, and side fork 3 is parallel with the longitudinal axis of acromioclavicular joint spacer 1, and gapped between side fork 3 and acromion sheet 2, it is sharp-pointed that side is pitched 3 front ends, and its length is less than or equal to the length of acromion sheet 2.
In Fig. 4, show, acromioclavicular joint spacer 1 adopts telescopic connection with acromion sheet 2, and acromioclavicular joint spacer 1, side fork 3 and acromion sheet have the fine motion of 5 °-10 °, more meet the physiological activity feature of acromioclavicular joint.The acromioclavicular joint spacer 1 of Micromovement fixing plate for dislocation of acromioclavicular joint is fixedly connected with clavicle 7 by locating hole 4 use screws, and the crotch 5 of both sides is held clavicle 7 tightly.The side fork 3 of acromioclavicular joint spacer 1 side-lower 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 plate and acromion.Side fork 3 also can be inserted into acromion 8 times, locking screw or common screw 6 can be set on acromion sheet 2, utilize screw that acromion sheet 2 is fixed on acromion 8, lock screw is only passed the cortex of acromion 8 tops, and not through the cortex of its below, avoid occurring acromion and clash into syndrome.As be common screw 6, inserting screw can not be long, avoids damaging shoulder joint, or causes acromion to clash into syndrome.
Above content is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
