Embodiment 1

[0033] Example 1: Non-invasive fixation

[0034] 1) Preparation: There are 4 specifications of skin staplers, including 2mm, 4mm, 6mm, and 8mm stretch strips 2, and the stretch strip 2 is used together with the paste board 1; The release paper pasted by the pasting film 14 on the back side of the following pasting board 1, pasting board 1 is pasted on the treated skin by the pasting film 14.

[0035] 2) Stretch strip 2 penetrates through the opening 15 of the pasting board to release the mechanical lock 13 times, and pulls the soft and slender stretching strip 2 until the stretching strip 2 is pulled to the side wall plate 173 of the opening , blocked by the stretch bar baffle plate 22, and the two pasting boards 1 approach gradually.

[0036] 3) When the locking elbow 134 is pressed down, the locking protrusion 133 at the bottom of the locking bottom plate 132 falls into the rack 21, which can fix the tension bar 2; The locking convex strip 133 is separated from the rack 21...

Abstract

The invention relates to the technical field of medical instruments, in particular to a skin anastomat. The skin anastomat comprises two sticking plates and a stretching strip. The two sticking plates are oppositely arranged and connected through the stretching strip. When the stretching strip is stretched, the two sticking plates gradually and oppositely move to get close to each other. The sticking plates are provided with releasing mechanical lock catches, oval through holes and horizontal through holes. Sticking films adhere to the back portions of the sticking plates. The sticking plates, the sticking films and the stretching strip are made of flexible materials. The skin anastomat is flexible in position fixing and can be fixed in an instrusive mode or a non-instrusive mode; to prevent ultrahigh shearing stress on the skin, the releasing mechanical lock catches and a stretching strip baffle are adopted; the stress can be evenly distributed in a large range, the wound tension can be released, skin injuries are avoided, and the wound surface is closed by constantly or intermittently stretching the skin in one direction or multiple directions.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a skin stapler. Background technique [0002] The principle of stretching the skin to promote the primary closure of wounds has been widely used to treat various skin injuries, such as tissue expanders on the scalp or exposed parts, to assist wound healing and reduce scar formation; tissue expanders are essentially It is invasive and needs to be pre-placed under the skin and gradually expanded, and then taken out to suture the skin again. Therefore, at least two operations are required to close this kind of wound, and there will be local tissue tension, which often leads to problems such as necrosis of the wound edge tissue . [0003] Patent CN 205041473 U discloses a skin stapler, which includes a fixed adhesive plaster, a clamping device, a joint of the clamping device and an anastomotic tie. The clamping device and the clamping device are integrated in an integrat...
