Wound closer

Abstract

The invention discloses a wound closer, belongs to the field of medical supplies, and provides a wound closer which is not prone to causing skin injury and not prone to falling off. The wound closer comprises two skin sticking pieces used for being connected with the skin surfaces on the two sides of a wound and a wound pulling and closing device which is arranged between the two skin sticking pieces and connected with the two skin sticking pieces, wherein the skin sticking piece comprises a main body sticking layer connected with the wound pulling and closing device and a flexible sticking part connected to the edge of the peripheral part or the edge of the whole circle of the main body sticking layer. The invention solves the problems that the skin sticking piece not only has good tension bearing and dispersing performance, but also can flexibly adapt to the dynamic change of the complexity of a plurality of curved surfaces of a wound, and keeps the sticking effectiveness and firmness, so that the skin sticking piece is particularly suitable for sticking a wound, which is formed by a plurality of curved surfaces or spliced planes, on a special movable part of a human body.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a wound closure. Background technique [0002] A wound closure, also known as a wound stapler, a wound healing device, or a wound closure, is a device used to close a wound to promote wound healing. A common wound closure is to draw the skin sticking parts pasted on the skin on both sides of the wound together by using tensioning parts on both sides of the wound, and then drive the wound skin edges of the skin on both sides of the wound to draw and close in the middle. However, conventional wound closures are only suitable for the adhesive closure of wounds on both sides of the wound, such as the abdomen and back of the human body, which are roughly in the same relatively static plane; Wounds composed of flattened surfaces in a plane, such as wounds on special parts of the human body: such as maxillofacial, head and neck, breast, armpits, knees, elbows, limb joints and other acti...

AI Technical Summary

Problems solved by technology

However, conventional wound closures are only suitable for the adhesive closure of wounds on both sides of the wound, such as the abdomen and back of the human body, which are roughly in the same relatively static plane; Wounds composed of combined surfaces in a plane, such as wounds on special parts of the human body: such as maxillofacial, head and neck, breast, armpits, knees, elbows, limb joints and other active parts

Because the skin adhesive surfaces on both sides of the wound in this special part of the human body are usually composed of multiple curved surfaces or multiple spliced ​​surfaces that are not in the same plane, so the skin adhesive surfaces on both sides of the incision cannot be included in the same static in a single overall plane

Moreover, the relative position, direction of movement, and angle changes of each individual combined surface are different during human body movement, and they are all in high-frequency asynchronous movement changes, resulting in the entire skin paste composed of a single structure, which cannot adapt to multiple skins. The asynchronous movement between two independent splitting surfaces, when the movement direction between any two adjacent splitting surfaces is not synchronous, will cause the skin stickers on these two adjacent splitting surfaces to produce partial peeling, which will cause Warping, falling off, pasting failure

At this time, if the entire skin adhesive composed of a single structure is set to be very flexible, its ability to bear, disperse and transmit the tension of the retractor will be significantly weakened; if the flexibility disappears, it will be even less able to adapt to or cushion multiple independent spliced ​​​​surfaces The asynchronous movement between them is more likely to cause the skin adhesive to peel off or fall off from the adjacent spliced ​​​​surface, and it is impossible to guarantee the effectiveness and firmness of the paste, and it is easy to fall off and fail

At the same time, because the pulling force it bears cannot be evenly dispersed or properly buffered, the pulling force is locally concentrated, and it is very easy to cause skin damage such as skin strain and tension skin blisters; Clinically effective closure of site wounds
