Description

Anchoring clamp

Technical Field

The utility model relates to an abdominal cavity operation auxiliary instrument, specific theory relates to an anchoring clamp.

Background

Endoscopic Submucosal Dissection (ESD) is a new treatment means appearing in recent years, is a technology with good clinical application prospect, enables more early digestive tract cancers to be completely resected under an endoscope at one time, and avoids the risk of open surgery and the pain of organ resection.

The anchoring clamp is used as a clamping device under monitoring of an endoscope and X-ray, is used for marking lesion tissues and providing guidance for a feeding position of a surgical instrument, and is a common auxiliary instrument in the process of endoscopic submucosal dissection surgery. The application method of the anchoring clip comprises the following steps: after the position of the pathological change tissue is confirmed, the anchoring clamp is inserted into a cavity channel of a human body through an endoscope and clamped on the pathological change tissue to serve as a position mark, after the pathological change tissue is clamped by the clamping part, the release part is disconnected from the clamping part and retreats, and the clamping part stays on the pathological change tissue to provide the cutting-in position guide for the scalpel.

The existing anchoring clamp cannot be opened again under the control of the release part after the far end of the clamping part is closed, and when the existing anchoring clamp is used in actual clinical practice, due to normal peristalsis of a human body cavity, the clamp is easy to slip off from tissue to be clamped when being closed to a half, at the moment, the anchoring clamp needs to be taken out, so that the anchoring clamp is clamped for the second time after being opened again, and the use process is inconvenient.

In view of the above problems, the chinese published patent CN 202699219-a tissue hemostatic clamping device provides a solution: the clamping piece is connected with the connecting piece into a whole, so that the clamping part can smoothly move in the retraction pipeline, the two clamping arms of the clamping piece can be repeatedly opened and closed under the action of the upper wall and the lower wall of the tightening pipe, the tightening pipe is relatively fixed, the hemostatic clamping device can clamp the living tissue for multiple times, after the clamping piece is occluded with the tissue to be hemostatic, the release mechanism is separated from the clamp, the clamp is detained in the body of a patient, and after the wound in the body of the patient naturally heals, the clamp automatically falls off. This solution solves the problem that the clamping device cannot be opened and closed repeatedly, but it is not suitable for the hemostatic surgery, but it is not suitable for endoscopic submucosal dissection, because endoscopic submucosal dissection directly resects the diseased tissue, rather than stanching the blood against the tissue, the anchoring clip is aimed at marking the position, and the marked position can be on the diseased tissue, or in the vicinity of the diseased tissue, therefore, in some cases, after the surgery is completed, the clip of the clamping part needs to be opened to prevent it from causing secondary damage to the body tissue, and the above-mentioned published patent occurs in the case that the clip is disconnected from the release mechanism, the clip has damaged tissue.

In view of the above, there is a need for improved anchoring clips that are suitable for endoscopic submucosal dissection.

The anchor clamp of claim 1, wherein the first cantilever (111) is an X-lever type cantilever, the middle portion of the first cantilever is fixed on the wall of the clamping tube (11) along a direction perpendicular to the axis of the clamping tube (11), the snap-fit position (112) is disposed at the proximal end of the first cantilever (111), and when the distal end of the first cantilever (111) is pressed, the snap-fit position (112) at the proximal end of the first cantilever (111) is tilted outwards, so that the snap-fit portion (122) of the clip (12) is separated from the snap-fit position (112).

5. An anchoring clip according to claim 1, characterised in that said first cantilever is in the form of an arc-shaped blade in cross-section along the radial direction of the clamping tube (11).

6. An anchoring clip according to claim 1, characterised in that the middle part of the first cantilever is integrally formed or fixedly connected with the wall of the clamping tube (11).

7. An anchoring clip according to claim 1, wherein the first arm is provided with a stiffening rib for increasing the rigidity of the lever, the stiffening rib being integrally formed with or fixedly connected to the first arm.

8. An anchoring clip according to claim 1, characterised in that the first cantilever is formed by blanking or cutting on the wall of the clamp tube (11).

9. An anchoring clip according to claim 1, characterised in that the clip (12) or the clamping tube (11) is provided with a connecting part, one end of which is a locating end for connection to the clip (12) or the clamping tube (11) and the other end of which is a free end of the connecting part for connection to another anchoring clip or other anchoring clip.

10. An anchoring clip according to any one of claims 1 to 9, wherein two second arms (113) are provided on the wall of the clamping tube (11), said second arms (113) being lever-type arms, the proximal ends of which are adjacent to the distal ends of said first arms (111), and the distal ends of which are disposed at the distal ends of said clamping tube (11) and correspond to said clip (12), when the distal ends of said first arms (111) and the proximal ends of said second arms (113) are simultaneously pressed, the proximal ends of said first arms (111) are tilted outwards, so that the clip portion (122) of said clip (12) is separated from said clip portion (112), and the distal ends of said second arms (113) are tilted outwards, so that no clamping force is applied to said clip (12) and the distal ends of said clip (12) are easily opened.
