[0031] The technical solutions of the present application will be further described below in combination with specific embodiments, which are only used to more specifically describe the technical solutions of the present application, and should not be understood as limiting the protection scope of the present application.

[0032] For example, Figure 1As shown, this utility model provides a surgical cannula partitioning device, including a handle 8 and partitioning wing 9 fixedly connected to the handle 8. The partitioning wing 9 is arrow-shaped and includes multiple wing plates 9-1 extending in the same direction. Two adjacent wing plates 9-1 are at a certain angle. The surgical cannula partitioning device is detachably inserted into the internal channel of the cannula body 1.

[0033] Preferably, the partitioned winglet 9 comprises 2-5 identical winglets 9-1.

[0034] In this specific embodiment, the partitioned wing 9 includes four wing plates 9-1, with each pair of adjacent wing plates 9-1 forming a 90° angle.

[0035] On the side of the wing plate 9-1 near the handle 8, a row of semi-circular holes is arranged at fixed intervals along the direction of extension of the wing plate 9-1. In this embodiment, three semi-circular holes are arranged in the middle of each wing plate 9-1. The vertical distance between the center of the semi-circular hole farthest from the handle 8 and the tip of the partition wing 9 is 35mm. The center distance between any two adjacent semi-circular holes is 10mm. The semi-circular holes can be used to indicate the placement depth of the surgical cannula partitioning device during use, and can also be used to match the existing length model of the cannula.

[0036] Various types of surgical cannulas can be used, and specific cannulas can be selected from those provided in CN211093985U.

[0037] like Figures 2 to 8 As shown, the surgical cannula partitioning device is inserted into the internal channel of the cannula body 1. The cannula includes a tube body 1 with an internal through channel. Both ends of the tube body 1 are radially outward, and an inner flange plate 2 and an outer flange plate 3 are formed at both ends of the tube body 1. The width of the wing plate 9-1 matches the radius of the internal channel of the tube body 1, and the length of the wing plate 9-1 is greater than or equal to the total length of the cannula.

[0038] The outer flange plate 3 is provided with a slot, and the sealing cover 5 is provided with a corresponding protrusion that cooperates with the slot. The sealing cover 5 is detachably fixed to the outer flange plate 3 through the cooperation of the slot and the protrusion. The sealing cover 5 is elastic and has a through hole in the center for the surgical cannula partitioning device and subsequent medical instruments to pass through. The diameter of the through hole in the center of the sealing cover 5 is smaller than the diameter of the internal channel of the tube body 1.

[0039] A sealing sheet 6 is fixedly installed in the through channel inside the tube 1, and a cut 7 is provided in the center of the sealing sheet 6.

[0040] The tube body 1 is provided with external threads, and the silicone nut 4 is set on the tube body 1 through corresponding mating internal threads.

[0041] The handle 8 is a plate structure to ensure that the handle 8 does not block the partitioning wings 9 of the surgical sleeve partitioning device when the surgical sleeve partitioning device is inserted into the sleeve, and other shapes of the handle 8 that do not affect the use can also be used, such as a ring shape, a strip shape, etc.

[0042] Figure 7 A schematic view of the surgical sleeve partitioning device being inserted into a sleeve, Figure 8 A schematic view of the surgical sleeve partitioning device being inserted into a sleeve, Figure 7 A sectional view in the A-A direction, in use, first, the sleeve is placed at the surgical site, the tightness is adjusted by rotating the silica gel nut 4, then the wing plate 9-1 is inserted into the internal passage of the sleeve body 1 from the through hole in the center of the sealing cover 5, passes through the cutout 7 of the sealing piece 6, and is inserted out from the internal flange plate 2.

[0043] When the wing plate 9-1 of the surgical sleeve partitioning device is inserted into the sleeve, because the sealing cover 5 and the sealing piece 6 are deformed at the cutout 7 and are pressed by the wing plate 9-1, when the surgical sleeve partitioning device is stopped from being pushed inwards, the surgical sleeve partitioning device and the sleeve do not slide relative to each other.

[0044] The sealing cover 5 and the sealing piece 6 are made of silica gel or TPU soft material, when the surgical sleeve partitioning device is inserted into the sleeve, the sealing cover 5 and the sealing piece 6 are pressed by the surgical sleeve partitioning device and are supported at the outer extensions of the wing plates 9-1, forming multiple independent channels for the insertion of surgical instruments, because the sealing cover 5 and the sealing piece 6 are supported, the insertion of the channels is not affected.

[0045] When the surgical sleeve partitioning device is inserted into the sleeve, the wing plate 9-1 is pressed by the sealing cover 5 and the sealing piece 6, so that the wing plate 9-1 is fixed at the corresponding position after being inserted into the sleeve.

[0046] After the sleeve and the surgical sleeve partitioning device are installed and the surgical sleeve partitioning device is pushed to the appropriate position, the sleeve can be used. Figure 8 As shown, after the surgical sleeve is inserted, four areas are formed by the gaps between the wing plates 9-1 at the section of the external flange plate 3 of the sleeve, and surgical instruments can be operated in each area, so that the sleeve can be used by multiple instruments without interference.

[0047] The above only describes preferred embodiments of the present application, and is not used to limit the present application, any equivalent replacement, modification, etc. made by those skilled in the art within the spirit and principles of the present application without any creative labor should be included in the protection scope of the present application.
