Description

Technical Field

[0001] The utility model relates to the field of surgical supplies, in particular to an incision protective cover for head and neck endoscopic surgery. Background Art

[0002] The neurovascular system in the head and neck region is complex. Currently, most head and neck surgeries are performed using open surgery, in which an incision is made in the head and neck area. A retractor is then used to pull the incision edges to expand the surgical field. However, the retractor is in direct contact with the skin edge, which can easily cause damage to the skin edge and cause additional harm to the patient. Utility Model Content

[0003] In view of the above problems, the utility model provides an incision protection cover for head and neck endoscopic surgery, which has a simple structure, is easy to process, and has low cost. It can effectively protect the incision wound edge and reduce the damage caused by the retractor directly pulling the skin edge.

[0004] The technical solution of the utility model is as follows:

[0005] An incision protective cover for head and neck endoscopic surgery, comprising:

[0006] An elastic bracket, wherein the elastic bracket has at least one clamping portion, the clamping portion is a semi-enclosed structure such as an arc shape, a U shape or a C shape, and the opening of the clamping portion is smaller than its maximum inner diameter, and two end points of the clamping portion extend to the same side thereof with an extension portion, and at least one of the clamping portions is connected through the extension portion;

[0007] The side edge of the elastic film is connected to the clamping portion and the extending portion of the elastic support, so that the elastic film and the elastic support together form a semi-enclosed tubular structure.

[0008] The working principle of the above technical solution is as follows:

[0009] The incision protection cover of the utility model is composed of an elastic support and an elastic film, and the whole is a semi-enclosed tubular structure. The use length can be adjusted according to the length of the surgical incision, and can be used in conjunction with the head and neck surgical retractor system. Before the retractor is placed, the utility model is put on the skin edge of the incision, and the elastic film of the incision protection cover is stretched by the elastic support. A part of the elastic support is located on the skin surface, and a part is located under the skin. The clamping part is used to assist in fixing so that the elastic film can wrap the skin edge. In addition, the surgical incision is stretched to be approximately circular. When placed, the extension part of the elastic support cooperates to bend, and its restoring force produces retraction, so that the elastic film is stretched and fitted to the skin edge to play a fixing role. Thereafter, the head and neck surgical retractor is placed, and the incision protection cover is pulled up together with the skin edge, which can avoid damage caused by directly pulling the skin edge.

[0010] In a further technical solution, the plane where the extension portion is located is perpendicular to the plane where the clamping portion is located.

[0011] In a further technical solution, the elastic bracket is made of a thermoplastic elastomer material and has good flexibility and resilience.

[0012] In a further technical solution, the elastic film is made of polypropylene and has good biosafety.

[0013] In a further technical solution, there are two clamping parts, which are respectively located at two ends of the extension part.

[0014] In a further technical solution, the number of the clamping parts is not less than three and they are distributed at equal intervals.

[0015] In a further technical solution, the number of the clamping portion is one, which is located at one end of the extension portion, and the ends of the two extension portions away from the clamping portion are close to each other to facilitate auxiliary fixation of the distal end.

[0016] In a further technical solution, the side edge of the elastic film is wrapped around the clamping portion or the extension portion and then bonded and fixed.

[0017] In a further technical solution, the connection between the clamping portion and the extension portion is an arc transition to avoid scratching the patient's incision tissue.

[0018] The beneficial effects of the utility model are:

[0019] 1. The incision protection cover of the present invention is composed of an elastic support and an elastic film, and the overall structure is a semi-enclosed tubular structure, which can be used in conjunction with a head and neck surgical retractor system. Before placing the retractor, the present invention is placed on the skin edge of the incision, and the elastic film of the incision protection cover is stretched by the elastic support. A portion of the elastic support is located on the skin surface, and a portion is located under the skin. The clamping portion is used to assist in fixing so that the elastic film can wrap the skin edge. In addition, the surgical incision is stretched to be approximately circular. When placed, the extension portion of the elastic support is bent in coordination, and its restoring force generates retraction, stretching the elastic film to fit the skin edge, thereby playing a fixing role. Thereafter, the head and neck surgical retractor is placed, and the incision protection cover is pulled up together with the skin edge, which can avoid damage caused by directly pulling the skin edge.

[0020] 2. The specific use length of the incision protective cover of the utility model can be determined by cutting according to the incision length. One end of the protective cover can be shortened or both ends can be cut, and only the extension part can be retained for use. The elastic force of the extension part after bending can be used to ensure stable fixation.

[0021] 3. The materials used in the utility model are thermoplastic elastomer and polypropylene, the raw materials are easily available, the cost is low, the structure is simple, the processing is convenient, and it is easy to promote, and it has high economic value and use value.

A part of the elastic bracket 10 is located on the skin surface, and a part is located under the skin. The clamping part 11 is used to assist in fixation, so that the elastic film 20 can wrap the skin edge. In addition, the surgical incision is stretched to be approximately circular. When placed, the extension part 12 of the elastic bracket 10 cooperates to bend, and its restoring force produces retraction, so that the elastic film 20 is stretched and fitted to the skin edge to play a fixing role. Thereafter, the head and neck surgical retractor is placed, and the incision protection cover is pulled up together with the skin edge to avoid damage caused by directly pulling the skin edge.

[0035] In another embodiment, the plane where the extending portion 12 is located is perpendicular to the plane where the clamping portion 11 is located.

[0036] In another embodiment, the elastic bracket 10 is made of thermoplastic elastomer and has good flexibility and resilience.

[0037] In another embodiment, the elastic film 20 is made of polypropylene, which has good biosafety.

[0038] In another embodiment, if Figure 2 As shown, there are two clamping portions 11 , which are respectively located at two ends of the extending portion 12 .

[0039] In another embodiment, if Figure 3 As shown, the number of the clamping parts 11 is not less than three and they are distributed at equal intervals.

[0040] In another embodiment, if Figure 4 As shown, there is one clamping portion 11 located at one end of the extension portion 12 , and the ends of the two extension portions 12 away from the clamping portion 11 are close to each other, so as to assist in fixing the distal ends.

[0041] In another embodiment, the side edge of the elastic film 20 wraps around the clamping portion 11 or the extending portion 12 and is then bonded and fixed.

[0042] In another embodiment, the connection between the clamping portion 11 and the extending portion 12 is an arc transition to avoid scratching the patient's incision tissue.

[0043] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
