Description

Technical Field

[0001] The utility model relates to a surgical instrument, in particular to a skin incision tension reducer. Background Art

[0002] The working principle of the skin tension reducer is that the adhesive tape on both sides of the wound is attached to the skin, and the device is fixed on the adhesive tape. By tightening the device, the two sides of the wound are brought closer to each other to avoid tensile stress. This allows the wound to heal well and reduces scar hyperplasia.

[0003] For example, a "knob-fastened skin tension reducer" disclosed in Chinese patent literature has a publication number of CN217510537U, which includes an adhesive film, a fixed frame strip, a fixed column, a buckle, a knob, and a traction strip. The adhesive film is used to fix the skin tension reducer on the skin on both sides of the wound. The fixed frame strip is fixedly connected to the skin adhesive film, and a traction strip, a buckle and a knob are installed thereon. The fixed column is connected to the fixed frame strip and is used to fix one end of the traction strip. The buckle and the other end of the traction strip cooperate with each other to lock the traction strip. The knob is located on the outside of the buckle and is used to tighten the traction strip for tightening and rolling the traction strip onto the shaft of the knob. The skin tension reducer replaces the traditional pull ring structure with a knob structure, so that the traction strip with serrations or locking holes can be rolled onto the knob structure to prevent the traction strip from extending or being left out, thereby preventing damage to the skin, wounds or scratching clothes. The structure is simple and reliable, and the operation is relatively convenient. However, the shortcoming of this patent is that its structure for reducing tension is too complicated. It has a hard structure and protrudes from the skin surface. It is easy to fall off and fail when hit. It cannot be used in the parts of the body that are under pressure or where friction occurs. Utility Model Content

[0004] The utility model aims to overcome the problem in the prior art that skin incision tension reducers are too complicated and cannot be applied to compressed parts of the body and parts where friction occurs. A skin incision tension reducer is provided, which has a simple structure and can be arranged to fit the skin, so that it can be applied to compressed parts of the body and parts where friction occurs.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model discloses a skin incision tension reducer, comprising at least two bottom plates, which are connected by an adjustment structure. The adjustment structure comprises a draw rope, and the bottom plate is provided with a plurality of draw rope guide structures. The draw rope guide structure comprises two draw rope guide openings, and a rope head fixing portion is provided at one side of the bottom plate.

[0007] Since the drawstring is a flexible structure, it will not be damaged by pressure, friction or collision through the drawstring guide, and by controlling the thickness of the drawstring, it can also be ensured that the skin and wound will not be damaged when under pressure. The drawstring guide port can be directly set on the bottom film by punching, cutting, stamping, etc., and will not protrude from the bottom film, which also avoids skin injuries.

[0008] Preferably, an independent adjustment portion is provided between the two drawstring guide openings, the independent adjustment portion includes a first fixing portion and a second fixing portion, and the drawstring includes an adjustment margin portion located between the first fixing portion and the second fixing portion. Through the independent adjustment portion, a single drawstring guide structure can be tightened locally. When the incision is located at a relatively uneven position of the skin, the skin around the incision can be more evenly stressed by tightening the drawstring locally, thereby improving the tension reduction effect. The adjustment margin portion allows the drawstring at that location to have sufficient adjustment when stretched. The first fixing portion and the second fixing portion can fix the adjustment margin portion.

[0009] Preferably, a first cutting line is provided between the first fixing part and the second fixing part. The first cutting line allows the entire bottom sheet to be separated from the cutting position. After separation, the first fixing part and the second fixing part can become new rope end fixing parts for fixing the rope ends after cutting. Through the above structure, the present application can achieve the effects of free length adjustment and free combination.

[0010] Preferably, a skin adhesive layer is installed on the lower side of the backsheet. The pulling force between the backsheets can be transferred to the skin through the skin adhesive layer, thereby achieving a tension-reducing effect.

[0011] Preferably, the drawstring guide opening is a cutting hole or a punching hole, which will not form a raised structure on the base film. At the same time, it can ensure that the drawstring can be limited there. Since there are two drawstring guide openings in a single drawstring guide structure in the present application, the tightened part of the drawstring can always be located on the upper side of the base film, preventing the drawstring from pressing on the wound.

[0012] Preferably, the side of the bottom sheet facing the skin incision is the incision side, and the drawstring guide structure further comprises two second cutting lines extending from the incision side to the inner side of the bottom sheet. Through the second cutting lines, one side of the drawstring guide structure can be turned up relative to the skin adhesive layer, and the turning up facilitates the adjustment and tightening of the drawstring position.

[0013] Preferably, the side of the bottom film facing the skin incision is the incision side, and the drawstring guide structure further includes two third cutting lines extending from the incision side to the inner side of the bottom film, and the part between the two third cutting lines forms an upward flip structure, and the upward flip structure is provided with two limiting notches, and the drawstring guide opening is formed between the limiting notches and the main body of the bottom film. With the above structure, the drawstring can be guided only by cutting the bottom film, making the device easier to manufacture and lowering the cost.

[0014] Preferably, the tension reducing device further comprises a first base film, a second base film and a third base film, wherein the first base film and the second base film are connected by a first drawstring, the second base film and the third base film are connected by a second drawstring, and the third base film and the first base film are connected by a third drawstring. With this structure, a triangular tension reducing area can be formed, so that the device can be applied not only to linear incisions but also to surface scars.

[0015] Preferably, the tension reducer also includes a first base film and a second base film installed on the first skin adhesive layer, and a third base film and a fourth base film installed on the second skin adhesive layer, the first base film and the third base film are connected by a first draw rope, and the second base film and the fourth base film are connected by a second draw rope.

[0016] Preferably, the drawstring includes a plurality of parallel tension-reducing parts, and the plurality of tension-reducing parts of the first drawstring and the plurality of tension-reducing parts of the second drawstring are arranged alternately. With this structure, the two bottom sheets on a single skin adhesive layer are mutually tightened, and the overall force on the skin at the incision is increased without affecting the tension when adjusting the drawstring.

[0017] Therefore, the utility model has the following beneficial effects: (1) The structure is simple and flat, without any hard structure. Even if it is installed in a pressure-bearing part, a joint movable part, or a friction part, it is not easy to fall off or damage the incision; (2) It can be locally adjusted, which is more suitable for the case where the incision is located in an uneven position on the skin; (3) The length of the device can be adjusted according to the incision situation; (4) It can reduce tension on special nonlinear incisions or scars; (5) The tension reduction effect can be improved without affecting the tension when adjusting the pull rope.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Embodiment 1, as Figure 1-3 As shown, a skin incision tension reducer comprises two bottom sheets 1, the bottom sheets 1 are 0.3 mm thick plastic sheets, the two bottom sheets 1 are connected by an adjustment structure, the adjustment structure comprises a drawstring 2, the drawstring 2 is a 0.3 mm elastic rope, the bottom sheet 1 is provided with a plurality of drawstring 2 guide structures, the drawstring 2 guide structure comprises two drawstring guide openings 3, a rope end fixing part 4 is provided at one side of the bottom sheet 1, one end of the drawstring 2 is fixed to the rope end fixing part 4 of one of the bottom sheets 1, the other end passes through the drawstring guide openings 3 of the two bottom sheets 1 in sequence, and the end is fixed to the rope end fixing part 4 of the other bottom sheet 1. A skin adhesive layer 5 is installed on the lower side of the bottom sheet 1, the skin adhesive layer 5 is a 0.5 mm thick anti-allergic adhesive tape. The rope end fixing part 4 comprises a 0.3 mm wide notch and a rope end fixing hole with a diameter of 0.4 mm.

[0027] The drawstring guide opening 3 is a cutting hole or a punching hole, and its diameter is 1mm. The distance between the two rope end fixing holes of the drawstring 2 guide structure is 11mm. The cutting hole and the punching hole will not form a protruding structure on the base film 1, and at the same time, it can ensure that the drawstring 2 can be limited there. Since there are two drawstring guide openings 3 in a single drawstring 2 guide structure in the present application, the tightened part of the drawstring 2 can always be located on the upper side of the base film 1, avoiding the drawstring 2 from pressing the wound.

[0028] Since the drawstring 2 is a flexible structure, it will not be damaged by pressure, friction or collision through the guide of the drawstring 2. Moreover, by controlling the thickness of the drawstring 2, it can also be ensured that the skin and wound will not be damaged when under pressure. The drawstring guide port 3 can be directly set on the bottom sheet 1 by punching, cutting, stamping, etc., and will not protrude from the bottom sheet 1, thus avoiding skin injuries. The tension between the bottom sheet 1 can be transmitted to the skin through the skin adhesive layer 5, thereby achieving a tension reduction effect.

[0029] An independent adjustment portion is provided at the middle position of the two drawstring guide openings 3, and the independent adjustment portion includes an independent cutting opening 6, and the independent adjustment portion includes a first fixing portion 7 and a second fixing portion 8, and the drawstring 2 includes an adjustment margin portion 9 located between the first fixing portion 7 and the second fixing portion 8. The first fixing portion 7 and the second fixing portion 8 are bilaterally symmetrical structures, and their size characteristics are the same as those of the rope end fixing portion 4. A first cutting line 10 is provided between the first fixing portion 7 and the second fixing portion 8. Through the independent adjustment portion, the guide structure of a single drawstring 2 can be tightened locally. When the incision is located at a relatively uneven position of the skin, the skin around the incision can be more evenly stressed by tightening the drawstring 2 locally, thereby improving the tension reduction effect. The adjustment margin portion 9 allows the drawstring 2 at this location to have sufficient adjustment when stretched. The first fixing portion 7 and the second fixing portion 8 can fix the adjustment margin portion 9. The first cutting line 10 allows the entire bottom film 1 to be separated from the cutting position. After separation, the first fixing portion 7 and the second fixing portion 8 can become new rope end fixing portions 4 for fixing the cut rope ends 12. Through the above structure, the present application can achieve the effects of free length adjustment and free combination.

[0030] The side of the bottom sheet 1 facing the skin incision is the incision side, and the guide structure of the drawstring 2 further includes two second cutting lines 11 extending from the incision side to the inner side of the bottom sheet 1. Through the second cutting lines 11, one side of the guide structure of the drawstring 2 can be turned up relative to the skin adhesive layer 5, and the turning up facilitates the adjustment and tightening of the position of the drawstring 2.

[0031] When the device leaves the factory, it is in a fully assembled state, that is, the two bottom sheets 1 are installed on the skin adhesive layer 5, and the drawstring 2 passes through the drawstring guide opening 3 in sequence to connect the two bottom sheets 1 together. When in use, the skin adhesive layer 5 is adhered to the skin around the incision, and then the two bottom sheets 1 are retracted by tightening the two rope ends 12. When the rope ends 12 are tightened, the rope ends 12 will not fall out of the rope end fixing holes due to the limiting effect of the notches. When the two bottom sheets 1 are retracted, the skin adhesive layer 5 exerts pressure on the skin, which has a tension-reducing effect. After the drawstring 2 between the two drawstring guide openings 3 is partially tightened, the rope ends 12 are knotted and fixed to the rope end fixing holes.

[0032] When the device is applied to an uneven skin position, the drawstring 2 at a certain position can be tightened by tightening the adjustment margin portion 9, so that the tensioning degree of the drawstring 2 on the same bottom film 1 is different, which is more adaptable. When the length of the device needs to be adjusted, the bottom film 1 and the corresponding adjustment margin portion 9 only need to be cut through the first cutting line 10.

[0034] The drawstring guide opening 3 is a cutting hole or a punching hole, and its diameter is 1mm. The distance between the two rope end fixing holes of the drawstring 2 guide structure is 11mm. The cutting hole and the punching hole will not form a protruding structure on the base film 1, and at the same time, it can ensure that the drawstring 2 can be limited there. Since there are two drawstring guide openings 3 in a single drawstring 2 guide structure in the present application, the tightened part of the drawstring 2 can always be located on the upper side of the base film 1, avoiding the drawstring 2 from pressing the wound.

[0035] Since the drawstring 2 is a flexible structure, it will not be damaged by pressure, friction or collision through the guide of the drawstring 2. Moreover, by controlling the thickness of the drawstring 2, it can also be ensured that the skin and wound will not be damaged when under pressure. The drawstring guide port 3 can be directly set on the bottom sheet 1 by punching, cutting, stamping, etc., and will not protrude from the bottom sheet 1, thus avoiding skin injuries.

Through the independent adjustment portion, the guide structure of a single drawstring 2 can be tightened locally. When the incision is located at a relatively uneven position of the skin, the skin around the incision can be more evenly stressed by tightening the drawstring 2 locally, thereby improving the tension reduction effect. The adjustment margin portion 9 allows the drawstring 2 at this location to have sufficient adjustment when stretched. The first fixing portion 7 and the second fixing portion 8 can fix the adjustment margin portion 9. The first cutting line 10 allows the entire bottom film 1 to be separated from the cutting position. After separation, the first fixing portion 7 and the second fixing portion 8 can become new rope end fixing portions 4 for fixing the cut rope ends 12.
