Description

Technical Field

[0001] The present invention relates to the technical field of joint dislocation reduction, and particularly relates to a joint dislocation reduction device. Background Art

[0002] Acromioclavicular joint dislocation is a common sports injury, accounting for about 12% of all shoulder injuries. It mostly occurs in contact sports such as rugby, football, hockey, skiing, or when falling while cycling. The acromioclavicular joint is a synovial joint between the acromial end of the scapula and the distal end of the clavicle, and its stability is maintained by the joint capsule, acromioclavicular ligament, coracoclavicular ligament, etc. When the shoulder is abducted 90°, the stress on the acromioclavicular joint is twice the body mass of the human body. When the acromioclavicular joint is dislocated, pain and swelling occur in the acromioclavicular joint area, and the entire upper limb loses the suspension of the clavicle and scapula, causing the upper limb to droop, which will seriously affect the function of the entire upper limb.

[0003] In a device for reducing acromioclavicular joint dislocation with the application number CN201320819800.7, when a patient with acromioclavicular joint dislocation uses this reduction device, take a sitting or standing position, adjust the height of the axillary pillow so that the axillary pillow is placed in the affected axilla of the patient, flex the elbow joint to 90 degrees, abduct the upper arm slightly, adjust the position of the elbow joint support, fix the elbow joint in the elbow joint support, slowly pull the elbow joint through the pull rod, and gradually externally rotate the upper arm, then adduct and internally rotate the elbow joint along the chest wall. When a reduction sound is heard, it indicates that the reduction is successful.

[0004] In a positioning and reduction integrated guide for acromioclavicular joint dislocation repair surgery with the application number CN202220043365.2, the problems of inaccurate device positioning, uncontrollable reduction degree, and lack of enhancing the applicability and repair stability of the device are solved. By applying the limiting devices for the clavicle and coracoid process, the position of the bone tunnel is ensured, and the surgical safety is increased; through the cooperation of the pressure rod and the pressure nut, the surgery is precisely controllable; and it has small trauma, convenient operation, and can complete the preparation of the bone tunnel and the reduction of the clavicle at one time, avoiding the errors of empirical reduction, and at the same time facilitating the fixation of the surgeon during the operation.

[0005] However, in the actual use process, due to the structural limitations of the mechanical mechanism, the structure cannot adjust the angle between the clavicle and the coracoid process, resulting in inaccurate positioning of the positioning device. It is impossible to adjust the opening and closing angle according to the severity of the joint dislocation, and there is a problem that the opening and closing angle cannot be adjusted. This makes it impossible to perform corresponding grasping and positioning according to the bone conditions of different patients, and the adaptability is poor.

[0072] It should be noted specifically that, please refer to Figure 21, the limiting block 100 is a cylinder with a diameter the same as that of the clavicle bone tunnel. Preferably, the diameter of the limiting block 100 is slightly larger than that of the clavicle bone tunnel. The outer surface of the limiting block 100 is provided with a threaded section, and a groove is opened at the center of the top of the limiting block 100, and the groove is one of a straight slot, a cross slot, and a cross-star slot.

[0073] Preferably, in this embodiment, the groove is set as a cross groove, which is convenient for matching with a screwdriver.

[0074] It should be noted that please refer to Figure 9 and Figure 11 , the driver shank 51 is a hollow rod, a wire channel communicating with the inner cavity of the driver shank 51 is opened in the handle 52, a traction ring 54 is integrally formed at the top end of the rivet head 53, the traction ring is detachably embedded at the bottom end of the driver shank 51, and a PDS wire 55 is connected to the traction ring 54. The PDS wire 55 passes through the inner cavity of the driver shank 51 and exits from the wire channel in the handle 52.

[0075] The specific operation is as follows: Make a 1-cm small opening at the corresponding position of the coracoid process, then separate the muscle tissue here, and clamp the coracoid process holder 23 on the positioning arm 20 at the lower edge of the coracoid process 80. At the same time, make an incision parallel to the clavicle 90 about 1 cm long at the medial side of the acromioclavicular joint and the distal end of the clavicle 90. Manually rotate the guiding and pressing rod 30 to make the pressing head 33 clamp on the clavicle 90, so as to realize the pre-positioning of the clavicle 90 and the coracoid process 80. Then, adjust the depth of the positioning arm 20 embedded in the positioning body 10 according to the angle between the clavicle 90 and the coracoid process 80, and then adjust the angle between the positioning arm 20 and the positioning body 10 to facilitate the coracoid process holder 23 to face the coracoid process 80 directly, while the pressing head 33 faces the clavicle 90 directly. Then, lock the positioning arm 20 through the fixing bolt 40. For the schematic diagram, please refer to Figure 13 and Figure 14 .

[0076] After the pre-positioning and installation of the reset device are completed, by rotating the adjusting head 32, the pressing head 33 can be driven to move downward through the cooperation of the threaded rod 31 and the guiding threaded hole 13, so as to realize the reset operation of the clavicle 90 by the pressing between the coracoid process holder 23 and the pressing head 33. Use a hollow drill bit 60 to prepare a bone tunnel from the center of the clavicle 90 to the center of the coracoid process 80 through the guiding through hole 34. After the drilling is completed, the preparation work of the bone tunnel is completed, and the hollow drill bit 60 should be taken out in time. For the schematic diagram, please refer to Figure 15 .

[0077] Then insert the rivet driver 50 into the guiding through hole 34 on the guiding and pressing rod 30 until the rivet head 53 contacts the limiting gasket 70. For the schematic diagram, please refer to Figure 16 .

[0078] At this time, since the rivet head 53 is directly opposite the limit gasket 70, start rotating the handle 52 at this time. When using the handle 52, ensure the correspondence between the rivet head 53 and the limit gasket 70. When rotating the handle 52, the rivet head 53 can be driven to rotate by the screwdriver through-rod 51, and the rivet head 53 corresponds to the thread groove 71, and the rivet head 53 can be tightened and installed in the thread groove 71 on the limit gasket 70, so as to realize the pre-installation of the PDS wire. For the schematic diagram, please refer to Figure 17 .

[0079] Then manually pull the handle 52 upward. At this time, since the limit gasket 70 is limited and abuts against the coracoid bone canal on the coracoid process 80, at this time, the rivet head 53 and the screwdriver through-rod 51 are separated, so that the rivet head 53 stays in the coracoid bone canal, and the PDS wire 55 on the rivet head 53 naturally leads into the coracoid bone canal and the clavicle bone canal. Subsequently, take out the screwdriver through-rod 51 from the guiding and pressing rod 30. At this time, the PDS wire 55 extends out from the guiding through-hole 34 on the guiding and pressing rod 30, completing the installation operation of the PDS wire 55. For the schematic diagram, please refer to Figure 18 and Figure 19 .

[0080] Then install the limit block 100 at the bottom end of the screwdriver. Since a cross-shaped groove is provided at the center of the surface of the limit block 100, it is convenient to screw the screwdriver to rotate the limit block 100. Pass the screwdriver and the limit block 100 through the guiding through-hole 34 together, so that the limit block 100 abuts against the clavicle bone canal opening. At the same time, manually tighten the extended PDS wire 55 to realize the tension of the PDS wire 55. When the limit block 100 abuts against the clavicle bone canal opening, while pressing down the screwdriver, rotate the screwdriver so that the limit block 100 is embedded and installed at the clavicle bone canal opening, and the PDS wire 55 can be pressed tightly in the clavicle bone canal. Subsequently, take out the screwdriver, remove the guiding and pressing rod 30 from the clavicle 90, and remove the locator main body 10 from the coracoid process 80. At this time, the PDS wire 55 in the coracoid bone canal and the clavicle bone canal is in a tensioned state under the limitation between the limit gasket 70 and the limit block 100. Then tie and cut the PDS wire 55 at the limit block 100. For the schematic diagram, please refer to Figure 20 , at this time, the displaced clavicle 90 and coracoid process 80 are pulled through the PDS wire 55 between the limit block 100 and the limit gasket 70, and the incision is sutured layer by layer. The operation is completed.
