Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a shoulder arthroscopic sleeve with a retractor function. Background Art

[0002] During shoulder arthroscopy, the surgeon typically inserts an arthroscope (a small camera) into the patient's shoulder joint through a small incision to directly observe the internal structures of the joint and perform surgical procedures. However, the space inside the shoulder joint is relatively small, and the surrounding muscles, tendons, and other soft tissues may obstruct the surgical field of view, making the surgical procedure complicated and difficult. This is especially true in the subacromial area, where the surgical field of view is very limited due to the obstruction of the muscle tissue and synovial tissue surrounding the acromion.

[0003] When the existing shoulder arthroscopy sleeve is used, when the shoulder arthroscopy sleeve is inserted into the patient's shoulder joint, it is impossible to prevent synovial tissue from entering the shoulder arthroscopy sleeve, resulting in the synovial tissue blocking the operation field during the operation and making it inconvenient to remove the synovial tissue. Utility Model Content

[0004] Technical problems solved

[0005] In response to the above-mentioned shortcomings of the prior art, the present invention provides a shoulder arthroscopic sleeve with a retractor function, which can solve the problem in the prior art that the synovial tissue may enter the operating field of view during the insertion of the shoulder arthroscopic sleeve and is inconvenient to remove.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example:

[0027] Please refer to the attached Figure 1-4 This solution proposes a shoulder arthroscopy sleeve with a retractor function. The sleeve 1 is set as a tubular structure. When in use, the sleeve 1 is inserted into the patient's shoulder joint, so that the hollow part inside the sleeve 1 forms an operating space, which is convenient for medical staff to insert the arthroscope and surgical instruments and perform surgical operations.

[0028] The surface of the sleeve 1 is provided with a tooth groove 2, in which an adjustment switch 3 is adapted to be installed, and a retractor 4 is installed on the adjustment switch 3. The retractors 4 are arranged in two groups, symmetrically distributed and rotatably connected to the adjustment switch 3. The opening and closing of the two groups of retractors 4 can achieve the expansion of muscle tissue or synovial tissue. When the sleeve 1 is inserted into the patient's shoulder joint, if muscle tissue or synovial tissue enters the sleeve 1, the retractors 4 are regulated by the adjustment switch 3, so that the retractors 4 can expand the muscle tissue or synovial tissue, further exposing the obstructed area inside the sleeve 1, thereby providing a clearer and more stable surgical field of view.

[0029] Specifically, the adjustment switch 3 includes a position adjustment member 31 and an angle adjustment member 32. The position adjustment member 31 is used to adjust the sliding movement of the retractor 4 within the sleeve 1, thereby adjusting the position of the retractor 4 within the sleeve 1 and facilitating the retraction of muscle tissue or synovial tissue in different areas. The angle adjustment member 32 is used to adjust the opening and closing angles of the two sets of retractors 4 within the sleeve 1, allowing the two sets of retractors 4 to expand muscle tissue or synovial tissue to different extents, further adjusting the exposure area of ​​the surgical field to minimize tissue damage.

[0030] More specifically, the position adjustment member 31 includes a slider A311 slidably mounted within the tooth groove 2. A pressing member 312 is mounted on the slider A311 via a spring. The spring forces the pressing member 312 to engage with the tooth groove 2. During use, pressing the pressing member 312 overcomes the spring's elastic force, releasing the engagement between the pressing member 312 and the tooth groove 2. The pressing member 312 then pushes the slider A311 to slide within the tooth groove 2, thereby adjusting the position of the hook 4.

[0031] Slider A311 is provided with a mounting slot 313. The angle adjustment member 32 includes a slider B321 mounted within the mounting slot 313. Slider B321 also has a spring disposed therein. The spring engages slider B321 with the toothed slot 2 to maintain a fixed position. During use, pressing slider B321 releases the fixed engagement between slider B321 and the toothed slot 2. Further pushing slider B321 within the mounting slot 313 allows the angle between the two sets of hooks 4 to be adjusted.

[0032] The difference is that the angle adjustment member 32 also includes a guide block 322 connected to the slider A311. The guide block 322 is configured as a trapezoidal structure. The two sets of retractors 4 are rotatably connected to the slider B321, and the two sets of retractors 4 are located on either side of the guide block 322. When the slider B321 slides toward the guide block 322, the two sets of retractors 4 will come into contact with the surface of the slider B321. Under the restraining action of the slider B321, the opening and closing angle between the two sets of retractors 4 is increased, further enabling the two sets of retractors 4 to spread the muscle tissue or synovial tissue.

[0033] Furthermore, during the process of adjusting the position of the retractor 4, the limiting latching teeth on the latching groove 2 can prevent the retractor 4 from rebounding due to tissue elasticity, thereby ensuring the structural stability of the device.

[0034] It is worth noting that a waterproof membrane 5 is provided at the rear end of the sleeve 1. Since physiological saline needs to be injected into the shoulder joint tissue during shoulder arthroscopic surgery, after the medical device is inserted from the rear end of the sleeve 1, the gap between the sleeve 1 and the medical device can be sealed through the waterproof membrane 5, effectively preventing physiological saline from flowing out from the rear end of the sleeve 1 during surgery, causing the water pressure in the joint to decrease, affecting the surgical field of view.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
