SUMMARY

[0003] In view of the above-mentioned deficiencies of the prior art, the utility model aims at providing a locking mechanism of skin anastomat with reasonable structure design.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] A locking mechanism of skin anastomat, characterized in that it comprises a first fixed locking member and a second fixed locking member, wherein the first fixed locking member comprises a first fixed sheet and a locking tooth sheet, the first fixed sheet is provided with a locking tooth sheet at one end, the locking tooth sheet is formed by forming a plurality of inclined teeth on the top of the base sheet, and one or more pull sheet perforations for the pull sheet to pass through are provided below or above the connection part of the fixed sheet and the locking tooth sheet at one end of the fixed sheet;The second fixed locking member comprises a second fixed sheet, a pull sheet, a locking seat, and a locking tooth, the side of the second fixed sheet opposite to the first fixed sheet is provided with a pull sheet and a locking seat, wherein the position of the pull sheet corresponds to the position of the pull sheet perforation one by one, and the position of the locking seat corresponds to the position of the locking tooth sheet, a locking tooth sheet perforation for the locking tooth sheet to pass through is provided on the locking seat, a locking tooth is provided above the locking tooth sheet perforation on the locking seat, and the locking tooth has elasticity, that is, the tooth groove of the locking tooth can be clamped into the tooth groove of the locking tooth sheet in the natural state, and the tooth groove can be released under external pressure.

[0006] Preferably, the above-mentioned pull sheet is two, and the two pull sheet perforations are respectively located on both sides of the locking tooth sheet.

[0007] Preferably, the free end of the above-mentioned locking tooth sheet is provided with a pull part for easy pulling.

[0008] Compared with the prior art, the utility model has the beneficial effects as follows:

[0009] The structure design of the utility model is simple and practical, can advance and tighten, also can retreat and release pressure, has better anastomosis effect, is easy to operate, has uniform force, and has no pain on the wound surface. BRIEF DESCRIPTION OF DRAWINGS

[0010] Fig. 1 It is the structure schematic view of the utility model;

[0011] Fig. 2 It is the bottom view angle solid structure schematic view of the first fixed locking piece of the utility model;

[0012] Fig. 3 It is the top view angle solid structure schematic view of the second fixed locking piece of the utility model. DETAILED DESCRIPTION

[0013] The utility model will be further described in connection with the drawings. The following undetailed parts are according to the prior art in the field. In this paper, the terms related to the connection relationship, such as "fixed connection", "connection" are carried out in the conventional way, such as specific bonding etc.

[0014] For example, Figs. 1-3As shown, the locking mechanism of the skin anastomat comprises a first fixed locking piece and a second fixed locking piece. The first fixed locking piece comprises a first fixed sheet 1 and a locking tooth sheet 2. The bottom of the first fixed sheet 1 is connected with a sticking part, and the first fixed sheet 1 is stuck on one side of the skin wound through the sticking part. One end of the first fixed sheet 1 is integrally formed with a fixing seat 3, and the other end of the fixing seat 3 is integrally formed with the locking tooth sheet 2. The other end of the locking tooth sheet 2 is a narrow arc end, which is a pulling part 2.1. A plurality of locking inclined teeth 2.2 are formed on the top of the locking tooth sheet 2. The inclination direction of the inclined teeth 2.2 is set to correspond to the tension direction of the two fixed locking pieces. Adjacent two inclined teeth are locking tooth grooves (i.e. the resistance generated in the tension state is small, and the resistance generated in the loosening state is large). A pulling piece through hole 3.1 for the pulling piece 5 to pass through is formed on the fixing seat 3 and located on both sides of the locking tooth sheet 2. The pulling piece through hole 3.1 penetrates through the left and right sides of the fixing seat 3, and the pulling piece through hole 3.1 is arranged in an upper and lower staggered manner with the locking tooth sheet 2.

[0015] In use, the first fixed sheet and the second fixed sheet are respectively stuck on both sides of the skin wound, then the two pulling pieces 5 are respectively passed through the corresponding pulling piece through holes 3.1, and the locking tooth sheet 2 is passed through the locking tooth sheet through hole 6.1, then the two hands respectively pull the pulling piece and the locking tooth sheet to the appropriate position. When it is needed to retreat, especially when the skin heals to form a protrusion, the top of the locking tooth can be pressed, the bottom of the locking tooth is separated from the locking tooth groove, and the two fixed sheets are pulled outwards, so that the extrusion force caused by the protrusion can be relieved.
