[0034] like Figures 1 to 5 As shown, the embodiment of the present application provides an orthopedic arthroscopic surgery auxiliary device, including a needle sleeve 100, a puncture needle 200 and a plurality of expansion members 300. The needle sleeve 100 is arranged to be axially penetrated. The puncture needle 200 includes a mounting rod 210 and a tip 220, the mounting rod 210 is detachably mounted in the needle sleeve 100 and is penetrated by the needle sleeve 100, and the tip 220 is connected to one end of the mounting rod 210 and is located outside the needle sleeve 100. The plurality of expansion members 300 are all mounted on the outer periphery of the needle sleeve 100.

[0035] It should be noted that the axial direction above and below refers to the bidirectional direction of the central axis defined by the structure of the needle sleeve 100 itself. Figure 2 The X-axis shown in .

[0036] Specifically, when using the device, the medical staff first installs the puncture needle 200 in the needle sleeve 100. The medical staff aligns the tip 220 and the needle sleeve 100 with the incision, and extends the needle sleeve 100 and the installation rod 210 into the joint through the tip 220. The medical staff inflates the expansion member 300 through an external inflation device, and the expansion member 300 begins to expand. The medical staff then removes the installation rod 210 and the tip 220 from the needle sleeve 100. During the cleaning process, the medical staff can use different types of cleaning tools to enter and exit the sleeve 110.

[0037] The orthopedic arthroscopic surgery auxiliary device provided by the present application adopts a puncture needle 200. After the puncture needle 200 is installed on the needle sleeve 100, it is convenient for medical personnel to insert the needle sleeve 100 from the incision into the patient's joint. Compared with directly inserting the needle sleeve 100 from the incision into the patient's joint, it helps to improve the convenience of use. The needle sleeve 100 can prevent the cleaning tool from directly contacting the inner wall tissue of the patient's incision during the cleaning process, which can cause secondary damage to the inner wall tissue of the patient's incision. The protective effect is good, which is convenient for medical personnel to clean the lesion site and helps to improve the convenience of use. The expansion piece 300 is adopted. After the needle sleeve 100 is inserted from the incision, it expands to help improve the stability between the needle sleeve 100 and the inner wall of the incision, and it is not easy to loosen.

[0038] In one embodiment of the present application, see Figures 1 to 5 The needle sleeve 100 includes a sleeve 110 and a plurality of mounting grooves 120 . The plurality of mounting grooves 120 are all disposed on the outer circumference of the sleeve 110 and are used for mounting a plurality of expansion members 300 .

[0039] With such a configuration, the sleeve 110 can be used to prevent the cleaning tool from directly contacting the inner wall tissue of the patient's incision during the cleaning process, thereby preventing the inner wall tissue of the patient's incision from being damaged again, thereby achieving good protection. A plurality of mounting grooves 120 can be used to mount a plurality of expansion members 300. Compared with directly mounting a plurality of expansion members 300 on the outer periphery of the sleeve 110, a plurality of expansion members 300 can be embedded in the sleeve 110, which helps to improve the structural stability between the expansion members 300 and the sleeve 110, and is not easy to fall off, thereby enabling the sleeve 110 to be stably placed in the patient's incision.

[0040] In one embodiment of the present application, please refer to Figures 1 to 5 The mounting groove 120 includes a connecting groove 121 and a plurality of windows 122. The connecting groove 121 is opened in the sleeve 110 and is used to install the expansion member 300. The plurality of windows 122 are all opened in the sleeve 110 and are connected to the connecting groove 121 and are arranged at intervals. The windows 122 are also configured to allow the expansion member 300 to bulge from the surface of the sleeve 110 after the expansion member 300 expands.

[0041] In this way, the connection groove 121 is used to facilitate the installation of the elastic airbag 310 into the connection groove 121. After the elastic airbag 310 is installed into the connection groove 121, the elastic airbag 310 is expanded by inflation. The plurality of windows 122 are used to allow the elastic airbag 310 to bulge from the plurality of windows 122. Compared with the direct bulge of the elastic airbag 310, it is helpful to increase the number of bulges of the elastic airbag 310, so that the connection between the sleeve 110 and the inner wall of the incision can be more stable and not easy to loosen, so that the sleeve 110 can be placed in the patient's incision more stably.

[0042] In one embodiment of the present application, see Figures 1 to 5 The orthopedic arthroscopic surgery assisting device further includes a protective film 400 , which is wrapped around the outer circumference of the sleeve 110 and the plurality of expansion members 300 .

[0043] Such a configuration, using the protective film 400, can make the surface of the device smoother than the multiple expansion members 300 and the sleeve 110 directly contacting the inner wall of the incision. When the device is inserted into the incision, scratches on the inner wall of the incision can be avoided, and the patient can be effectively protected.

[0044] In one embodiment of the present application, see Figures 1 to 5 The needle sleeve 100 further includes a cartridge seat 130 , which is mounted on one end of the sleeve 110 and can limit the position of the sleeve 110 along the axial direction.

[0045] With such arrangement, when the sleeve 110 is inserted into the incision, the sleeve 110 can be limited in the axial direction by the sleeve seat 130, so as to prevent the sleeve 110 from moving too deep and sinking into the incision. After the operation is completed, it is convenient for medical staff to take out the sleeve 110.

[0046] In one embodiment of the present application, please refer to Figures 1 to 5 A guide surface 140 is formed at one end of the sleeve 110 away from the cartridge seat 130 , and the guide surface 140 is gradually expanded along the axial direction from the end away from the cartridge seat 130 toward the end close to the cartridge seat 130 .

[0047] With such a configuration, the guide surface 140 can prevent the sleeve 110 from entering the incision and moving in the incision due to the thickness of the sleeve 110 itself. In addition, the sleeve 110 can be prevented from scratching the inner wall tissue of the incision due to the thickness of the sleeve 110 itself, which has a good protective effect and helps to improve the convenience of use.

[0048] In one embodiment of the present application, see Figures 1 to 5 The puncture needle 200 further includes a needle hub 230 , which is connected to an end of the mounting rod 210 away from the tip 220 .

[0049] With such a configuration, the needle seat 230 is used to prevent the mounting rod 210 and the tip 220 from moving too deep when the mounting rod 210 and the tip 220 are installed in the sleeve 110, thereby preventing the tip 220 from piercing the internal tissue of the joint, thereby effectively protecting the patient.

[0050] In one embodiment of the present application, see Figures 1 to 5The cylinder seat 130 is provided with a plurality of avoidance grooves 150, and the plurality of avoidance grooves 150 and the plurality of expansion members 300 are arranged one by one. The expansion member 300 includes an elastic airbag 310 and an air inlet and outlet passage 320, the elastic airbag 310 is installed in the connecting groove 121, and the air inlet and outlet passage 320 is installed in the elastic airbag 310 and is located in the avoidance groove 150.

[0051] With such a configuration, the elastic airbag 310 can be used to transport external gas into the elastic airbag 310 in cooperation with the inlet and outlet channels 320, so that the elastic airbag 310 expands, making the sleeve 110 and the inner wall of the incision fit more closely and not easy to get loose. In addition, in cooperation with the inlet and outlet channels 320, the gas in the elastic airbag 310 can be discharged, and the elastic airbag 310 automatically shrinks, making it easier for medical personnel to take out the sleeve 110, which helps to improve the convenience of use.

[0052] In one embodiment of the present application, please refer to Figures 1 to 5 The inner wall of the sleeve 110 close to the cartridge seat 130 is provided with a first threaded section 160. The outer wall of the mounting rod 210 away from the tip 220 is provided with a second threaded section 240.

[0053] In this way, the sleeve 110 and the mounting rod 210 can be detachably connected by using the first threaded section 160 and the second threaded section 240, and the disassembly and installation are convenient. In addition, by utilizing the self-locking property of the threaded connection, when the sleeve 110 is inserted into the incision, it is possible to prevent the mounting rod 210 and the tip 220 from moving relative to the sleeve 110, which makes it more difficult for the sleeve 110 to be inserted into the incision, thereby helping to improve the convenience of use.

[0054] In one embodiment of the present application, see Figures 1 to 5 The outer periphery of the sleeve 110 is provided with anti-slip grooves (not shown in the figure).

[0055] Such a configuration and the use of anti-slip grooves help to increase the friction between the protective film 400 and the sleeve 110, so that the protective film 400 and the sleeve 110 fit more closely and are not easy to fall off.

[0056] One or more embodiments of the present application are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the present application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of the present application should be included in the protection scope of the present application.
