Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an incision protector that prevents tumor cell implantation. Background Technology

[0002] During surgery, incision protectors are widely used to prevent contamination and damage to the incision edges. Traditional incision protectors are usually made of a single layer of material. While they can protect the incision to some extent, they may still cause secondary damage or contamination when removed after surgery. In practice, when harvesting tumor tissue, if the tumor is too large, the pressure exerted during removal from the abdominal cavity can cause tumor cells to implant onto the surface of the incision protector. When the incision protector is removed after surgery, tumor cells may still implant on the incision. This situation is especially common in laparoscopic surgery where small incisions are chosen to minimize invasiveness, leading to the awkward situation where the incision protector is ineffective.

Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] This utility model provides a surgical incision protector to prevent tumor cell implantation, comprising: an insertion ring 100, an outer ring 200, and a double-layer protective film 300; the outer ring 200 is disposed above the top of the insertion ring 100, and the double-layer protective film 300 is fixedly connected between the outer ring 200 and the insertion ring 100; the double-layer protective film 300 is designed to be tearable.

[0023] The tearable design of the double-layer protective film 300 solves the problem of secondary damage or contamination that may be caused by the removal of traditional incision protectors after surgery, while improving the aseptic protection effect during the operation.

[0024] In one embodiment, the double-layer protective film 300 includes an inner protective film 310 and an outer protective film 320. An insertion ring 100 and an outer ring 200 are fixedly connected to the outer protective film 320. The top end of the inner protective film 310 is connected to the inner side of the outer protective film 320, while the bottom end of the inner protective film 310 is separate from the outer protective film 320. The inner protective film 310 can be peeled off from the outer protective film 320. The inner protective film 310 has a dotted break line 311, allowing it to be peeled off along the dotted break line 311.

[0025] The outer protective membrane 320 is made of a flexible material that can adapt to different incision shapes and sizes, providing basic incision protection. The inner protective membrane 310 is connected to the outer protective membrane 320 via a dotted line 311, facilitating quick removal after surgery.

[0026] For example, the double protective film 300 is made of a transparent or semi-transparent sterile material to facilitate observation of the incision area.

[0027] For example, the surface of the double protective film 300 may be coated with an antimicrobial coating, such as a silver ion coating or a chlorhexidine coating, to further reduce the risk of infection.

[0028] For example, the inner protective film 310 is fixed to the outer protector by a peelable adhesive.

[0029] For example, the insertion ring 100 and the outer ring 200 are made of medical-grade silicone or polyurethane material, which has good flexibility and biocompatibility.

[0030] For example, the double protective film 300 is made of transparent or translucent polyethylene or polypropylene material with a thickness of 0.01 mm to 0.1 mm to ensure its flexibility and tearability.

[0031] For example, the tear line 311 is made using laser cutting or die-cutting processes to ensure smooth tearing.

[0032] In one embodiment, the edge of the inner protective film 310 is provided with a tear-off label 312, which is convenient for the operator to grab and tear off.

[0033] For example, the outer wall of the double protective film 300 is evenly distributed with raised textures to increase surface friction.

[0034] For example, the double protective film 300 axially surrounds itself to form an internally hollow sleeve.

[0035] The double-layer protective film 300 has a drum-shaped structure with diameters at both ends larger than the diameter in the middle.

[0036] A wound protector designed to prevent tumor cell seeding is placed at the surgical incision site, ensuring that the double protective membrane 300 completely covers the incision. During the procedure, the inner protective membrane 310 provides additional sterile protection against incision contamination. After the procedure, the operator grasps the tear-off label 312 and peels off the inner protective membrane 310 along the dotted line 311. Finally, the main body of the wound protector is removed using routine procedures, completing the removal of the wound protector.

[0037] This invention provides a surgical incision protector that prevents tumor cell implantation. By attaching a removable protective film to the inner layer, it achieves true surgical incision protection, solving the problem of secondary damage or contamination that may occur when traditional surgical incision protectors are removed postoperatively. Furthermore, its simple design and easy operation make it suitable for various surgical scenarios and have broad application prospects.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
