The specific meaning of the terms in the present disclosure may be understood as appropriate by those of ordinary skill in the art.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.

Although the existing tissue clip (closing clip) has the advantages of convenient operation, reasonable price and the like, the existing tissue clip (closing clip) has the limitations of diameter span limit and difficult operation when closing a large wound surface, and the purse string suture and OTSC devices have complex operation and higher cost, so that a closing clip capable of avoiding the limitations is needed.

Based on this, this disclosed embodiment provides a closed clamp, sets up first clamping part longer than second clamping part, like this when closing great postoperative surface of a wound, can let second clamping part support the normal mucous membrane at the surface of a wound edge of art person's proximal end, and first clamping part supports the normal mucous membrane at the surface of a wound edge of art person's distal end, overcomes the diameter and strides limit and the difficult problem of operation.

The closing clip is described in detail below by way of specific examples:

referring to fig. 1 to 3, the present disclosure provides a closure clip, including a clip body 1, a release sleeve 2, and a driving device, wherein the clip body 1 includes a first clamping portion 11 and a second clamping portion 12, the head ends of which can be relatively opened or closed, and in the embodiment of the present disclosure, the clip body 1 is two titanium alloy plates (sheets) disposed in a crossing manner, and a scissor-like principle drives the first clamping portion 11 and the second clamping portion 12 to relatively open and close. In addition, the head end of the clip body 1 of the present disclosure is one end connected with the first clamping portion 11 and the second clamping portion 12, and the tail end is the opposite end; the tail ends of the first clamping part 11 and the second clamping part 12 are one ends connected with the clamp body 1, and the head ends are the opposite ends.

Specifically, the tail end of the clip body 1 is connected with the inside of the release sleeve 2 through a connecting piece, wherein the release sleeve 2 is a prefabricated component connected with the existing excitation gun, and how the traction clip, the hemostatic clip and the occlusion clip are released through the excitation gun is the prior art in the field, and the details are not repeated here; the driving device is connected with the clip body 1 to drive the first clamping part 11 and the second clamping part 12 to open or close, and can be a driving structure such as a connecting rod structure, a gear structure and the like, which is similar to the principle of the scissors, and aims to be connected with the excitation gun to control the opening and closing of the first clamping part 11 and the second clamping part 12 in vitro

Furthermore, the first clamping part 11 and the second clamping part 12 of the present disclosure are provided with pulling teeth 3 at the head ends, the pulling teeth 3 are used for pulling the edges at two sides of the wound surface, and the wound surface is closed by utilizing the closing of the first clamping part 11 and the second clamping part 12 to pull the edges at two sides of the wound surface; preferably, the traction teeth 3 can be rounded so as to be capable of pulling up the normal mucous membrane, and preferably avoid scratching the normal facial mask too sharply. More importantly, in the present disclosure, the first clamping portion 11 is longer than the second clamping portion 12, or the second clamping portion 12 is longer than the first clamping portion 11 to form a "long and short leg" structure, and the present disclosure defines the longer clamping portion as the first clamping portion 11. The existing clip has the limitation of diameter span limit and difficult operation due to smaller operation space when closing a large wound surface, and the long and short legs structure of the present disclosure can enable the short legs to partially prop against the normal mucous membrane of the wound surface edge of the proximal end of an operator and the long legs to prop against the normal mucous membrane of the wound surface edge of the distal end of the operator when closing the wound surface after the large operation as shown in fig. 3, so that the operation space can be reduced, and the problems of diameter span limit and difficult operation can be overcome. Preferably, the length of the second clamping portion 12 is two-thirds of the length of the first clamping portion 11. In another embodiment, the second clamping portion 12 is one half the length of the first clamping portion 11.

In a preferred embodiment of the present disclosure, due to the arrangement mode of the long and short leg structures, two sets of traction teeth 3 are disposed on the first clamping portion 11 of the present disclosure, the two sets of traction teeth 3 are disposed at intervals along the extending direction of the first clamping portion 11, and one set of traction teeth 3 is disposed opposite to the traction teeth 3 on the second clamping portion 12, so that the first clamping portion 11 (long leg) can more fully pull the normal mucosa in the pulling process. Preferably, one set of the pulling teeth 3 of the first clamping portion 11 is disposed at the head end of the first clamping portion, and the pulling teeth 3 on the second clamping portion 12 are disposed at the head end of the second clamping portion 12.

In some embodiments of the present disclosure, the pulling tooth 3 has a bearing surface 5, the bearing surface 5 being used to bear against the mucosa when the first clamping portion 11 and the second clamping portion 12 are closed to the wound surface. Preferably, the support surface 5 is provided with anti-slip patterns 6 to avoid slipping.

In some embodiments of the present disclosure, the pulling tooth 3 includes a tooth tip 31 and a body 32, the tooth tip 31 is connected to the first clamping portion 11 and the second clamping portion 12 by the body 32, the tooth tip 31 and the body 32 together form the bearing surface 5, and the tooth tip 31 and the body 32 are detachably connected. The detachable connection mode can be a screw connection mode, a clamping connection mode and the like. The main purpose is that the operator will conduct a consultation planning procedure prior to surgery to select a suitable patient instrument size (e.g. angles, various tooth 3 arrangements as described above), but may go to emergency situations during surgery where significant time is wasted in the case of a desired patient-adapted instrument. In the detachable connection embodiment, the operator can automatically match the shape and the size of the tooth tip 31 or the whole pulling tooth 3 if the special situation happens, so that the accidental situation in the operation can be better treated.
