The joint fixing piece 4 and the buckle 5 are connected with the fixing plate in an integrated injection molding mode, a mechanical matching mode or an adhesive bonding mode.

When in use, when the crochet hook component connected below the joint 2 is a one-way crochet hook, taking the embodiment shown in fig. 3 and 4 as an example, firstly, the crochet hook 1 connected with the joint 2 is respectively arranged in the joint fixing piece 4 on the fixing plate 3 in a way that the directions of the hooks are opposite, then the crochet hook 1 below one fixing plate 3 is inserted into one side of a wound, the fixing plate 3 is attached to the skin, and then the crochet hook 1 below the other fixing plate 3 is inserted into the other side of the wound in a way that the directions of the hooks are opposite, and the other fixing plate 3 is attached to the skin; or, the fixing plates 3 are respectively attached to two sides of the skin wound, then the crochet hook 1 of the crochet hook component is respectively inserted into a proper position and an angle through the crochet hook groove 10 on the fixing plates 3, and finally the joint 2 of the crochet hook component is firmly fixed through the joint fixing part 4. When the crochet hook component is a bidirectional crochet hook, taking the embodiment shown in fig. 5 to 7 as an example, firstly, one fixing plate 3 is attached to one side of a skin wound, then the crochet needles 1 below two adjacent joints 2 are respectively penetrated into the skin in a manner of opposite hook directions, then the two adjacent joints 2 are assembled together through a concave-convex groove, finally, the two assembled joints 2 are installed in a joint fixing piece 4 on one fixing plate 3, and the other fixing plate 3 is attached to the skin by operating the other fixing plate 3 according to the same steps. When the wound is small, only one stretching assembly and two symmetrical crochet hook assemblies are needed, and the crochet hook assemblies are one-way crochet hooks, taking the embodiment shown in fig. 1 to 3 as an example, the joint 2 and the joint fixture 4 connected with the crochet hook assemblies can be assembled together in advance before use. If be provided with from type paper 13, tear earlier from type paper 13 the back, paste the viscose face of fixed plate 3 in wound both sides, laminate fixed plate 3 on skin. If the fixing plate 3 is provided with the preformed hole 11, whether a suture or a leather nail is needed to assist the fixation is evaluated according to the tension condition of the wound, and when the tension force of the wound is too large and the fixing plate 3 has a displacement tendency, the suture or the leather nail is used to assist the fixation through the preformed hole 11 on the fixing plate 3. Then the brace 6 penetrates through the through hole and the buckle 5 on the fixing plate 3, and the skin is drawn by drawing the brace 6. If the pulling is too tight or the tension is too high, the buckle can be lifted to pry the head 14, and the brace 6 can be retracted to the proper position.

When the skin on two sides of the wound is gradually pulled and stretched to the magnitude of the tension capable of being sutured, the wound is sutured or closed without continuously pulling, the suture or the skin nail in the reserved hole is removed (if the suture or the skin nail is sutured), then the connector fixing pieces are sequentially loosened, the connector and the hooked needle are taken out of the skin, then the buckle is lifted, the pulling strip is taken out, or the pulling strip is directly cut above the wound, and finally the fixing plate is taken down.

Although some specific embodiments of the present invention have been described in detail by way of illustration, it should be understood by those skilled in the art that the above illustration is only for the purpose of illustration and is not intended to limit the scope of the utility model. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the utility model.
