Description

Technical Field

[0001] The invention relates to the technical field of joint dislocation reduction, and in particular 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, and often occurs in contact sports such as rugby, football, hockey, skiing, or falls on bicycles. The acromioclavicular joint is a micro-motion joint between the acromion end of the scapula and the distal end of the clavicle. The stability of the joint is maintained by the joint capsule, acromioclavicular ligament, coracoclavicular ligament, etc. When the acromioclavicular joint is abducted 90°, the stress on the acromioclavicular joint is twice the 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 sag, which will seriously affect the function of the entire upper limb.

[0003] In a acromioclavicular joint dislocation reduction device with application number CN201320819800.7, when a patient with acromioclavicular joint dislocation uses the reduction device, the patient sits or stands, adjusts the height of the axillary pillow so that the axillary pillow is placed in the patient's affected armpit, flexes the elbow joint to 90 degrees, slightly abducts the upper arm, adjusts the position of the elbow joint support, fixes the elbow joint in the elbow joint support, slowly pulls the elbow joint through the traction rod, and gradually externally rotates the upper arm, then adducts and internally rotates the elbow joint along the chest wall, and hears the reduction sound, indicating that the reduction is successful.

[0004] An integrated positioning and reduction guide for acromioclavicular joint dislocation repair surgery with application number CN202220043365.2 solves the problems of inaccurate positioning of the device, uncontrollable reduction degree, and lack of enhanced device applicability and repair stability. By applying limiting devices for the clavicle and coracoid process, the position of the bone tunnel is ensured and the safety of the surgery is increased; the cooperation of the pressure rod and the pressure nut makes the surgery precise and controllable; it has low trauma and is easy to operate. The preparation of the bone tunnel and clavicle reduction are completed at one time, avoiding errors in empirical reduction and facilitating the operator's fixation during the operation.

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

[0006] Therefore, it is necessary to solve the above problems through a joint dislocation reduction device. Summary of the invention

The PDS line 55 passes through the inner cavity of the screwdriver rod 51 and comes out from the wire channel in the handle 52.

[0075] The specific operation is as follows: a small incision of 1 cm is made at the corresponding position of the coracoid process, and then after separating the flesh tissue there, the coracoid process clamping seat 23 on the locator arm 20 is clamped on the lower edge of the coracoid process 80. At the same time, an incision parallel to the clavicle 90 is made on the inner side of the acromioclavicular joint and the distal end of the clavicle 90, which is about 1 cm long. The guide pressure rod 30 is manually rotated to cause the pressure head 33 to be clamped on the clavicle 90, so that the clavicle 90 and the coracoid process 80 can be pre-positioned. Then, the depth of the locator arm 20 embedded in the locator body 10 is adjusted according to the angle between the clavicle 90 and the coracoid process 80, and then the angle between the locator arm 20 and the locator body 10 is adjusted to facilitate the coracoid process clamping seat 23 to face the coracoid process 80, and the pressure head 33 to face the clavicle 90. Then, the locator arm 20 is locked by the fixing bolt 40. Please refer to the schematic diagram. Fig.13 and Fig.14 .

[0076] After the reset device is pre-positioned and installed, by rotating the adjusting head 32, the pressure head 33 can be driven to move downward through the cooperation of the threaded rod 31 and the guide threaded hole 13, so that the reset operation of the clavicle 90 is achieved by the pressure between the coracoid clamping seat 23 and the pressure head 33, and the hollow drill bit 60 is used to prepare a bone channel from the center of the clavicle 90 to the center of the coracoid process 80 through the guide through hole 34. After drilling is completed, the preparation of the bone channel is completed, and the hollow drill bit 60 is taken out in time. Please refer to the schematic diagram Fig.15 .

[0077] Then insert the rivet driver 50 into the guide through hole 34 on the guide pressure rod 30 until the rivet head 53 contacts the limit washer 70. Fig.16 .

[0078] At this time, since the rivet head 53 is facing the limiting gasket 70, the handle 52 starts to be rotated. When the handle 52 is used, the correspondence between the rivet head 53 and the limiting gasket 70 is ensured. When the handle 52 is rotated, the rivet head 53 can be driven to rotate by the screwdriver rod 51, and the rivet head 53 and the thread groove 71 correspond to each other. The rivet head 53 can be tightened and installed in the thread groove 71 on the limiting gasket 70, so that the pre-installation of the PDS line can be achieved. Please refer to the schematic diagram. Fig.17 .

[0079] Then, the handle 52 is manually pulled upward. At this time, since the limiting gasket 70 is limited against the coracoid bone channel on the coracoid process 80, the rivet head 53 and the screwdriver rod 51 are separated, so that the rivet head 53 is retained in the coracoid bone channel, and the PDS wire 55 on the rivet head 53 is naturally introduced into the coracoid bone channel and the clavicle bone channel. Then, the screwdriver rod 51 is taken out from the guide pressure rod 30. At this time, the PDS wire 55 extends out from the guide through hole 34 on the guide pressure rod 30, and the installation operation of the PDS wire 55 is completed. Please refer to the schematic diagram Fig.18 and Fig.19 .

[0080] Then, the upper limit block 100 is installed at the bottom of the screwdriver. Since a cross-shaped groove is provided at the center of the surface of the limit block 100, it is convenient for the screwdriver to turn the limit block 100. The screwdriver and the limit block 100 are passed through the guide through hole 34 together, so that the limit block 100 abuts against the clavicle bone opening, and the extended PDS line 55 is manually tightened to achieve the tension of the PDS line 55. When the limit block 100 abuts against the clavicle bone opening, the screwdriver is pressed downward while the screwdriver is turned. , so that the limit block 100 is embedded in the clavicle bone channel, the PDS line 55 can be pressed in the clavicle bone channel, then the screwdriver is taken out, and the guide pressure rod 30 is removed from the clavicle 90, and the positioner body 10 is removed from the coracoid process 80. At this time, the PDS line 55 in the coracoid bone channel and the clavicle bone channel is in a tensioned state under the limit between the limit gasket 70 and the limit block 100, and then the PDS line 55 at the limit block 100 is knotted and cut. Please refer to the schematic diagram Fig. 20 At this time, the dislocated clavicle 90 and coracoid process 80 are pulled by the PDS line 55 between the limiting block 100 and the limiting gasket 70, and the incisions are sutured layer by layer to complete the operation.
