When it is necessary to adjust the overall length of the drill guide frame 2 and the positioning rod 21 according to needs, under the action of the spring 22, the limit frame 23 is pressed down, so that the limit frame 23 is lower than the internal height of the limit groove 20, and the positioning rod 21 is pulled and adjusted. When it moves to the position of the required limit groove 20, under the elastic force of the spring 22, the limit frame 23 is driven to reset, so that the limit frame 23 is stuck in the limit groove 20 to fix the overall length. The support plate 24 is driven by the positioning rod 21 to be inserted into the patient's body from the incision, so that the support plate 24 supports the lower part of the coracoid process and hooks the coracoid process, thereby enhancing the fitting connection effect and improving the convenience of positioning. Under the action of the groove 25, the aiming and positioning of the guide needle 7 are facilitated, and the difficulty of positioning is effectively reduced.

[0035] The working principle of the minimally invasive reduction and aiming device for acromioclavicular joint dislocation provided by the present invention is as follows: When in use, an incision channel is established at a suitable position of the acromioclavicular joint, the overall length of the drill guide frame 2 and the operating arm 1 is adjusted according to the actual conditions of different patients, and the fixing bolt 5 is used to fix and limit, and the limiting frame 23 is pressed down to make the limiting frame 23 disengage from the inner side of the limiting groove 20, and the limiting frame 23 is placed inside the drill guide frame 2 as a whole, and the positioning rod 21 is pulled out and adjusted, and the positioning rod 21 drives the limiting frame 23 to move to a suitable limiting groove 20 according to the patient's condition, and under the action of the spring 22, the limiting frame 23 is driven to reset, so that the limiting frame 23 The inner side of the limit groove 20 is inserted to determine the overall length of the drill guide frame 2 and the positioning rod 21, which is convenient for flexible adjustment according to needs, effectively expanding the scope of use and enhancing practicality. The adjusted positioning rod 21 is inserted through the incision, and the support plate 24 is placed at the base of the coracoid process and hooked on the coracoid process. The adjustment block 33 is inserted into the outer side of the operating arm 1 through the movable groove 6 and adjusted to a suitable position. Under the action of the two sets of bolts 8, nuts 9 and the fixing groove 32, it is convenient to fix the adjustment block 33 on the operating arm 1. Through the movable groove 6 and the placement groove 31, it is convenient to The sleeve 34 is inserted into the adjustment block 33 so that one end of the sleeve 34 extends out and rests against the patient's clavicle. Under the support of the stabilizing plate 10, the stabilizing rod 11 is rotated so that the stabilizing rod 11 drives the gasket 12 to descend, so that the gasket 12 contacts and fits the patient's skin, which is beneficial to cooperate with the sleeve 34 to enhance the stabilizing effect. The guide needle 7 is inserted into the sleeve 34, and the guide needle 7 is drilled through the clavicle and the base of the coracoid process, so that the tip of the guide needle 7 is aligned with the groove 25 on the support plate 24, which is beneficial to improve the aiming and positioning effect. According to the needs, the support box 41 is installed on the required side of the operating arm 1. The surface and position of the support box 41 are adjusted, and the control knob 19 is rotated under the support of the support box 41, so that the worm 17 rotates under the support of the stabilizing seat 18, and then drives the worm wheel 15 to rotate under the support of the support seat 16. Under the meshing action, the worm wheel 15 drives the rack 14 to run, and then the reset plate 43 moves downward on the inner side of the fixed cylinder 42, and the reset clamp 44 and the anti-slip pad 13 are driven to descend through the reset plate 43, effectively applying pressure on the dislocated part of the acromioclavicular joint, promoting the resetting of the dislocated acromioclavicular joint, realizing precise operation of the acromioclavicular joint, and improving the resetting success rate.
