[0002] In minimally invasive surgery, a multi-channel soft sheath tube is usually required, on which an incision protection cover is installed. The incision protection cover and the multi-channel soft sheath tube are installed through the elastic silicone ring that comes with the incision protection cover. The silicone ring is tightened on the soft sheath tube, and then the sealing ring of the soft sheath tube is used to press the incision protection cover from the outside of the incision protection cover to achieve the connection between the incision protection cover and the multi-channel soft sheath tube.

[0003] The connection between the multi-channel soft sheath tube and the incision protection cover mentioned above requires first putting the incision protection cover on the outside of the multi-channel soft sheath tube, and then fixing the incision protection cover by physically tightening the sealing ring when operating. When separating the incision protection cover and the multi-channel soft sheath tube, it is also necessary to remove the sealing ring first and then remove the incision protection cover, which leads to the problem of cumbersome installation and disassembly. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-channel soft sheath tube fixing ring, comprising a fixing strip, the left end of which is respectively fixedly connected to a limit strip and a compression strip, and the limit strip and the compression strip are combined into a U shape, the inner surface of the compression strip is provided with a first bite tooth, the fixing strip is soft and deformable, and the siege ring can be tightened on the outside of the incision protection sleeve to achieve a sealed connection between the incision protection sleeve and the multi-channel soft sheath tube;

[0006] The inserting strip is fixedly connected to the right end of the fixing strip, and a plurality of second teeth are arranged on the upper surface of the inserting strip. The inserting strip is inserted between the limiting strip and the pressing strip, and the second teeth are engaged with the first teeth to make the fixing strip form a ring shape. The second teeth and the first teeth can maintain the ring state of the fixing strip to prevent the problem of unstable sealing.

[0007] Furthermore, a first anti-skid block is fixedly connected to the upper surface of the compression strip, and a second anti-skid block is fixedly connected to the upper surface of the insertion strip. The first anti-skid block and the second anti-skid block are pinched to make the second biting teeth engage with the first biting teeth, which is easy to operate.

[0008] Furthermore, a tilting head is fixedly connected to the right end of the clamping strip, and the tilting head is used to separate the first biting tooth and the second biting tooth. The clamping strip is elastic, and the tilting head can be bent to close the first biting tooth and the second biting tooth so that they are no longer in contact.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] (1) The incision protection sleeve is put on the outside of the multi-channel soft sheath tube, and the fixing strip is surrounded on the outside of the incision protection sleeve. The first anti-slip protrusion and the second anti-slip protrusion are pinched to make the second biting teeth and the first biting teeth bite, so as to achieve the tightening effect of the incision protection sleeve. When removing the incision protection sleeve, the second biting teeth and the first biting teeth can be separated by bending the lifting head, thereby simplifying the installation and disassembly operations of the incision protection sleeve and the multi-channel soft sheath tube, and making it more convenient to use.

[0011] (2) A plurality of second bite teeth can be engaged with the first bite teeth, thereby adjusting the caliber of the multi-channel soft sheath tube interface, realizing the installation and fixing function of the fixing ring on the incision protective sleeves of different calibers, and improving the applicability of the fixing ring.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example:

[0018] See also Figures 1-3 The utility model provides a technical solution: a multi-channel soft sheath tube fixing ring, comprising a fixing strip 1, the left end of the fixing strip 1 is respectively fixedly connected to a limit strip 8 and a pressing strip 6, and the limit strip 8 and the pressing strip 6 are combined into a U shape, and the inner surface of the pressing strip 6 is provided with a first bite tooth 9;

[0019] The entire fixing ring is injection molded to ensure that the fixing ring is soft and bendable, which is conducive to the fixing strip 1 being attached to the surface of the multi-channel soft sheath tube;

[0020] The inserting strip 3 is fixedly connected to the right end of the fixing strip 1. A plurality of second teeth 4 are provided on the upper surface of the inserting strip 3. The inserting strip 3 is inserted between the limiting strip 8 and the pressing strip 6, and the second teeth 4 are engaged with the first teeth 9, so that the fixing strip 1 forms a ring. The plurality of second teeth 4 can be engaged with the first teeth 9. When the fixing strip 1 is surrounded by a ring, the diameter of the ring can be adjusted.

[0021] In this embodiment, if Figure 1 As shown, the upper surface of the clamping strip 6 is fixedly connected with a second anti-slip protrusion 5, and the upper surface of the insertion strip 3 is fixedly connected with a first anti-slip protrusion 2. Pinching the first anti-slip protrusion 2 and the second anti-slip protrusion 5 facilitates the insertion of the insertion strip 3 between the clamping strip 6 and the limiting strip 8, ensuring that the fixing strip 1 is tightened on the outside of the multi-channel soft sheath tube.

[0022] In this embodiment, if Figure 3 As shown, the right end of the clamping strip 6 is fixedly connected with a tilting head 7, which is used to separate the first biting tooth 9 and the second biting tooth 4. When the tilting head 7 is bent outward, the tilting head 7 drives the first biting tooth 9 to separate from the second biting tooth 4, and the fixing strip 1 is smoothly removed from the multi-channel soft sheath tube.
