Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a loop-and-ring artificial ligament structure for treating shoulder dislocation. Background Art

[0002] Shoulder dislocation is a common occurrence, and the vast majority of shoulder dislocations can be reduced manually. However, injuries caused by a primary shoulder dislocation, such as tears of the glenoid labrum, glenohumeral ligament, and joint capsule, as well as fractures of the glenoid rim (Bankart) and humeral head (Hillsach), cannot heal on their own once the shoulder is reduced. Repeated dislocations in similar situations often lead to recurrent dislocations, necessitating surgical treatment.

[0003] Recurrent dislocation of the shoulder is common in sports and daily life injuries. This is especially true in sports that require high shoulder strength, such as gymnastics, volleyball, weightlifting, wrestling, ski jumping, and other sports. The main surgical methods for recurrent dislocation of the shoulder are currently: arthroscopic surgery, open surgery, subscapularis insertion transposition, subscapularis and joint capsule overlap suture, scapular anterior lip and anterior joint capsule repair, and bone transplantation. For recurrent shoulder dislocation, one factor is the subscapularis muscle dysfunction or damage, which makes it impossible to maintain the normal position of the humeral head and glenoid fossa of the shoulder joint during movement. For recurrent shoulder dislocation, one factor is the subscapularis muscle dysfunction or damage, which makes it impossible to maintain the normal position of the humeral head and glenoid fossa of the shoulder joint during movement. Therefore, it is necessary to treat the subscapularis muscle dysfunction or damage. Utility Model Content

[0004] In response to the above problems, the utility model provides a loop artificial ligament structure for the treatment of shoulder dislocation, which can be used to bind the subscapularis muscle during shoulder dislocation surgery, and can also be used for ligament reconstruction of acromioclavicular joint dislocation, auxiliary treatment, and relief of patient pain.

[0005] The technical solution adopted by this utility model is:

[0006] A loop-and-ring artificial ligament structure for treating shoulder dislocation comprises an artificial ligament body. Both ends of the artificial ligament body are respectively provided with connecting loops. Each connecting loop is connected to a fixing buckle.

[0019] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0020] Figures 1 to 3This is a preferred embodiment of a loop-and-loop artificial ligament structure for treating shoulder dislocation provided by the present invention. The loop-and-loop artificial ligament structure for treating shoulder dislocation comprises an artificial ligament body 10, with connecting loops 20 provided at both ends of the artificial ligament body. Each connecting loop is connected to a fixing buckle 30, and the fixing buckle 30 is provided with two symmetrical holes 31 for the connecting loops to pass through. First, two holes are set at the position of the patient's subscapularis muscle. A guide wire is used to guide the connecting loop 20 and the fixing buckle 30 from the back of the shoulder through the shoulder holes to the front of the shoulder. The fixing buckle 30 blocks the hole in the front of the shoulder, thereby achieving the positioning of the artificial ligament body 10 on the subscapularis muscle at the back of the shoulder. The artificial ligament body 10 can be used to bind the subscapularis muscle during shoulder dislocation surgery, and can also be used for ligament reconstruction in acromioclavicular joint dislocation and other conditions, thereby facilitating shoulder reduction.

[0021] The fixing buckle 30 is oval in shape, and the widths of the two ends of the fixing buckle are smaller than the width of the middle part of the fixing buckle, so as to prevent the fixing buckle from passing through the hole and causing the artificial ligament body 10 to fall off.

[0022] The artificial ligament body 10 is provided with a connecting ring 11 connected to the connecting loop. This prevents the connecting loop from falling off the artificial ligament body 10 and facilitates the use of a guide wire to guide the connecting loop 20 through the patient's shoulder hole during surgery. The fixing buckle 30 is connected to the connecting loop 20 by first inserting the two ends of the connecting loop 20 through the two symmetrical holes 31 of the fixing buckle 30 from the front. Then, the two ends of the connecting loop 20 are crossed and passed through the connecting ring 11 of the artificial ligament body 10, and then respectively inserted through the two symmetrical holes 31 of the fixing buckle 30 from the back.

[0023] like Figure 1 As shown, the artificial ligament body 10 is C-shaped, and two connecting loops 20 are connected to the two ends of the artificial ligament body respectively. Figure 2 As shown, the artificial ligament body is O-shaped, and two connecting loops 20 are provided on the artificial ligament body. Figure 3 As shown, the artificial ligament body is Q-shaped, one end of the artificial ligament body 10 is a movable end, and the other end of the artificial ligament body 10 is a fixed end. A loop is formed on the fixed end for the movable end of the artificial ligament to pass through. Both connecting loops 20 are connected to the artificial ligament body 10, and one of the connecting loops 20 is connected to the fixed end of the artificial ligament body. The movable end of the artificial ligament body is also connected to a connecting line 40.

[0024] The artificial ligament body 10 is made of polytetrafluoroethylene or polyester fiber, which has excellent wear resistance and biocompatibility, can mimic the function of natural ligaments and provide stable support. The connecting loop 20 is made of polyester fiber, which is widely used in medical devices due to its excellent mechanical properties and biocompatibility.

[0025] like Figure 4As shown, when the loop-and-loop artificial ligament structure is used during surgery, two bone holes with a diameter larger than the width of the fixing buckle 30 are first drilled on the glenoid fossa at the lower part of the glenoid labrum behind the glenoid fossa, diagonally forward and upward. A guide wire is passed from the back to the front through the two holes and the subscapularis muscle, and the joint is pulled out from the front of the shoulder joint. The two guide wires are respectively connected to the connecting loops 20 at both ends of the artificial ligament body 10. The wires are pulled back backward to allow the fixing buckle 30 to pass vertically through the bone holes. The tightness of the connecting loop 20 is adjusted, and the fixing buckle 30 is clamped horizontally outside the bone hole in front of the glenoid fossa. The connecting loop 20 is tied, and the artificial ligament body 10 is tightened to the subscapularis muscle.

[0026] In summary, the technical solution of the present utility model can fully and effectively achieve the above-mentioned purpose of the utility model, and the structure and functional principles of the present utility model have been fully verified in the embodiments and can achieve the expected efficacy and purpose. Without departing from the principle and essence of the present utility model, various changes or modifications can be made to the embodiments of the utility model.
