[0032] Please refer to Figure 1 and Figure 2 The present invention provides a laparoscopic-assisted single-hole incision protection device in a preferred embodiment, which includes an incision protection tube 100, a connecting seat 200, a protection cover 300 and a compression sleeve 400.

[0033] The upper end of the incision protection tube 100 is provided with an outwardly flared first connecting skirt 110. The center of the connecting base 200 is provided with a center hole 210, the inner wall of which is internally threaded. The bottom of the center hole 210 is provided with an inwardly extending support ring 220. The center of the support ring 220 is formed with an escape hole 221 for the incision protection tube 100 to pass through. The bottom of the first connecting skirt 110 is in contact with the upper end surface of the support ring 220. The bottom of the protective cover 300 is embedded in the center hole 210. The bottom of the protective cover 300 is provided with an outwardly flared second connecting skirt 310, which is stacked above the first connecting skirt 110. The clamping sleeve 400 is threadedly connected to the center hole 210 and cooperates with the support ring 220 to clamp the first connecting skirt 110 and the second connecting skirt 310. Usually, the incision protection tube 100 and the first connecting skirt 110 are integrally formed and made of flexible material. When the compression sleeve 400 cooperates with the supporting ring 220 to clamp the first connecting skirt 110 and the second connecting skirt 310, the sealing effect is good and there is no need to use a sealing gasket.

[0034] The present invention provides a laparoscopic-assisted single-hole incision protection device. By designing a first connecting skirt and a second connecting skirt, and by using a compression sleeve 400 in conjunction with a support ring 220 to clamp the first connecting skirt 110 and the second connecting skirt 310, the incision protection tube 100 and the protective cover 300 are connected and fixed. At the same time, due to the threaded connection and compression of the compression sleeve 400, the airtightness of the connection between the incision protection tube 100 and the protective cover 300 is ensured. In addition, only by threading the compression sleeve 400 with the connecting seat 200 can the incision protection tube 100, the connecting seat 200, the protective cover 300 and the compression sleeve 400 be connected and fixed. The device is simple in structure, easy to manufacture and use, and convenient to assemble and process. The present invention comprises an incision protection tube, a connecting seat, a protective cover and a compression sleeve. The device has a simple structure and is easy to manufacture and use. The design of the first connecting skirt and the second connecting skirt makes the installation of the device more convenient and reduces the operating steps during surgery; the design of the incision protection tube can effectively protect the surgical incision and avoid accidental damage during surgery. The threaded connection between the compression sleeve and the connecting seat 200 can ensure the stability of the device during surgery and prevent displacement or falling off due to surgical operations.

[0035] Reference Figure 2 and Figure 4In some embodiments of the present invention, an upwardly extending first limiting bead 111 is provided on the outer peripheral edge of the first connecting skirt 110, and the second connecting skirt 310 is located within the inner ring of the first limiting bead 111. Thus, when the first connecting skirt 110 is compressed, the first limiting bead 111 limits the inward contraction of the first connecting skirt 110, preventing the first connecting skirt 110 from contracting inward and disengaging from the compression sleeve 400, thereby improving the stability of the device. The first connecting skirt 110 and the incision protection tube 100 are integrally connected. This integral connection structure can improve the connection strength and stability between the incision protection tube 100 and the first connecting skirt 110. During manufacturing, the incision protection tube 100 and the first connecting skirt 110 can be integrally manufactured, facilitating mass production, improving production efficiency, and reducing production costs. Furthermore, the integrated design reduces the number of components, improves the integrity of the structure, reduces the number of installation steps, and improves installation efficiency.

[0036] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the outer edge of the second connecting skirt 310 is provided with a second upwardly extending limiting bead 311, and the bottom surface of the compression sleeve 400 is provided with a bezel 410 for the second limiting bead 311 to be embedded in, thereby positioning and limiting the second connecting skirt 310, ensuring a stable connection to the protective cover 300. It is understood that the second connecting skirt 310 and the protective cover 300 can be an integrally connected structure, which can improve the strength and stability of the connection between the second connecting skirt 310 and the protective cover 300. During manufacturing, the second connecting skirt 310 and the protective cover 300 can be manufactured as a single piece, which facilitates mass production, improves production efficiency, reduces production costs, reduces the number of parts, improves the integrity of the structure, and improves installation efficiency.

[0037] Reference Figure 2 and Figure 4 In some embodiments of the present invention, a flange ring 420 protruding radially outward is provided at the upper end of the compression sleeve 400 , and the flange ring 420 fits against the upper end surface of the connecting seat 200 , thereby limiting the screwing depth of the compression sleeve 400 .

[0038] Reference Figure 2 In a further embodiment of the present invention, an operation hole 320 is provided at the center of the upper end of the protective cover 300, so as to facilitate operation of the instrument through the operation hole 320.

[0039] Reference Figure 1 and Figure 2In a further embodiment of the present invention, a sealing plug 340 is connected to the outer surface of the protective cover 300 via a connecting strap 330. Both the connecting strap 330 and the sealing plug 340 can be made of silicone or rubber. The sealing plug 340 is inserted into the operating hole 320, thereby sealing the operating hole 320 when the instrument does not need to be inserted into the operating hole 320. To facilitate the insertion and removal of the sealing plug 340, an extraction cap 350 is provided at the upper end of the sealing plug 340, which can be easily pinched to remove the sealing plug 340.

[0040] Reference Figure 1 and Figure 2 In a further embodiment of the present invention, the outer peripheral contour of the connecting seat 200 is a regular polygon, so that it is convenient to hold and operate when it is threadedly connected with the clamping sleeve 400. It can be understood that the outer peripheral contour of the flange ring 420 can also be a regular polygon, which is convenient for holding and screwing, increasing friction and facilitating operation.

[0041] In some embodiments of the present invention, the incision protection tube 100 is made of silicone material. Silicone is friendly to the human body, is not likely to cause human irritation or allergic reactions, and has excellent biocompatibility. Silicone can withstand a temperature range from -50°C to 200°C and is suitable for various medical environments and disinfection methods.

[0042] Reference Figure 3 In some embodiments of the present invention, a first support ring 120 is provided at the bottom of the incision protection tube 100, thereby supporting the contour of the bottom of the incision protection tube 100 and preventing the bottom contour of the incision protection tube 100 from tightening and affecting the operation of the instrument.

[0043] Reference Figure 3 In some embodiments of the present invention, a second support ring 130 is provided on the inner wall of the middle portion of the incision protection tube 100 to prevent the middle portion of the incision protection tube 100 from being tightened and affecting the operation of the instrument.
