[0002] In various surgical operations, it is usually necessary to make a vertical incision on the skin to form a surgical incision. For example, during laparoscopic thyroid surgery, the skin incision needs to be retracted to expand the surgical field of view and surgical channel. The skin incision is easily damaged by the traction of the instrument and the repeated friction of the surgical instrument rod. The skin tissue at the traction site does not circulate blood and becomes necrotic. At the same time, the skin incision is exposed to the outside, and the tissue is also prone to dryness and tissue dehydration damage.

[0003] In the prior art, for example, there is a skin incision protector with announcement number CN204520967U, which includes a fitting portion and a horizontal portion; the fitting portion and the horizontal portion are perpendicular; one end of the horizontal portion is provided with a sharp corner; the width of the horizontal portion is 0.5 to 1 cm; the height of the fitting portion is 0.5 to 4 cm. The skin incision protector is inserted into the edge of the skin incision, and the fitting portion is fixed by silk thread suture, which can effectively prevent the skin, subcutaneous tissue, muscle, peritoneum, etc. at the edge of the surgical incision from being damaged by sharp objects such as knives and scissors, blunt objects such as forceps and retractors, or thermal burns from electric knives, etc. However, during use, the above solution needs to be fixed with silk thread suture, which is more cumbersome to operate, and its shape conformity with the skin incision is also poor.

[0026] In order to make the present invention more clear, a skin incision protection strip of the present invention is further described below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0027] like Figure 1 As shown, a skin incision protection strip includes a U-shaped strip 100 made of a flexible and elastic material, the U-shaped strip 100 has a pair of straight sections 1 and an arc section 2, the two ends of the arc section 2 are respectively connected to the ends of the straight section 1 in an integral manner, the dimension between the connecting ends of the two straight sections 1 increases linearly to the dimension between the free ends, and an angle a is formed between the two straight sections. In this embodiment, the U-shaped strip 100 can be made of medical grade silicone or rubber, so that it has a softer touch and can also undergo good elastic deformation.

[0028] like Figure 2 As shown, the U-shaped groove 3 is arranged on the U-shaped profile path of the U-shaped bar 100, and the inner wall of the U-shaped groove 3 is smooth, and its opening is arranged toward the outer peripheral side. Here, the opening is arranged toward the outer peripheral side. Figure 2 In the figure, the opening of the U-shaped groove 3 faces the left and right sides, and is perpendicular to the paper surface and faces the reader.

[0029] In general, the U-shaped strip 100 is a flexible strip with a U-shaped cross section, which is bent into a U-shaped profile structure. The thickness of the strip can be 0.5 mm to reduce its space occupation.

[0030] The U-shaped groove 3 is used to hold the tissue at the skin incision, and the U-shaped groove 3 has an arc-shaped groove bottom 31 and two groove walls 32. The two groove walls 32 can be arranged in parallel with each other, or the opening ends of the two groove walls 32 can be arranged close to each other. The groove bottom 31 is used to contact and limit the tissue at the skin incision, the upper groove wall 32 is used to stick to the outside of the skin, and the lower groove wall 32 is used to stick to the lower side of the skin tissue, so that the U-shaped groove 3 can be stably engaged with the tissue at the skin incision.

[0031] In order to prevent the blood flow of the skin tissue at the contact part from being blocked and damaged or even necrotized when the device is stuck in the skin incision and clamped by the retractor, a group of first protrusions 4 are provided on the groove bottom 31 of the U-shaped groove 3, and the first protrusions 4 are spaced a certain distance apart to prevent the groove bottom 31 from being completely attached to the tissue section at the skin incision. The spacing between the first protrusions 4 can serve as a non-pressurized area, so that the blood in the skin tissue can flow through this area. Of course, the first protrusions 4 are not easy to be too dense or too sparse, and they can disperse the concentrated pulling force and provide a circulation path for the blood.

[0032] Furthermore, the first protrusion 4 is strip-shaped, and the length direction of the first protrusion 4 is consistent with the extension direction of the U-shaped groove 3. Of course, in some embodiments, the first protrusion 4 is dot-shaped, and the specific protrusion shape is preferably not to hinder the blood flow of the skin tissue.

[0033] In addition, a group of second protrusions 5 are provided on the groove wall 32 of the U-shaped groove 3, and the second protrusions 5 are spaced a certain distance apart from each other. The shape of the second protrusions 5 is strip-shaped or dot-shaped.

[0034] In order to facilitate the U-shaped strip 100 to be placed on the cut surface of the skin tissue and not to fall off, Figure 3 As shown, the angle a between the two straight sections 1 is preferably 10-30°.

[0035] When the device is used, the subcutaneous tissue at the skin incision 6 is first separated from the skin, and then the U-shaped strip 100 is bent and deformed so that the U-shaped groove 3 on one side is first clamped in the skin tissue 7 on the corresponding side, and then the U-shaped groove 3 on the other side is clamped in the skin tissue 7 on the corresponding side. At the same time, the arc section 2 is located at the end of the skin incision 6. Under the action of its own elasticity, the U-shaped strip 100 as a whole is consistent with the open shape of the skin incision 6. Specifically, Figure 4 As shown in Figure 5, two U-shaped strips 100 are used to completely protect the skin incision. Of course, in some small incisions, one U-shaped strip 100 can also be used to protect the incision.

[0036] During the above-mentioned use process, the device is simple to operate and convenient to use. It does not require suturing or other methods for fixation. The fixation purpose can be achieved through the U-shaped groove and its own elasticity. The U-shaped strip made of flexible material can adapt and match the shape of the skin incision. In addition, the device can effectively isolate the skin incision, avoiding the impact of repeated friction of the surgical instrument rod on the incision during the operation, and also reducing skin dryness and tissue dehydration damage. When the device is used in the skin retraction process, the retraction hook of the retraction device directly pulls on the U-shaped strip 100 to avoid direct contact with the skin incision tissue. The pulling force acts more evenly on the U-shaped strip 100, reducing the cutting and small-area squeezing of the skin. At the same time, the first protrusions arranged at intervals can prevent the skin tissue at the traction location from completely contacting the U-shaped strip 100, providing a blood circulation path for the skin tissue and preventing skin tissue necrosis.

[0037] The above embodiments of the utility model are merely examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the utility model still belong to the protection scope of the utility model.
