The pouch forceps are generally composed of a forceps head, a connecting rod and a forceps handle. The forceps head is generally composed of nine forceps teeth. In the process of thoracic surgery and gastrointestinal surgery, the forceps head is used to clamp the tissue first, and then the notch is locked tightly, so that the tissue is clamped naturally, and part of the tissue is extruded into the gap of the notch. Then the pouch needle is inserted into the notch, and after the notch is released, the suture is pulled to make pouch suturing. By using the pouch forceps to make pouch suturing of stomach, esophagus, intestinal tube and the like, at present, laparoscopic minimally invasive surgery is widely used in clinical application, and gradually replaces conventional surgery with large incision due to its advantages of small trauma and rapid recovery. However, the existing pouch forceps are not exclusively used for laparoscopic minimally invasive surgery, and the size is large, so it cannot be used under total laparoscopy. The closer is usually used instead of the pouch forceps to disconnect the intestinal tube in the conventional total laparoscopic surgery, and then the intestinal tube is cut open, the low nail seat is inserted, and then it is closed again. After being closed, the disconnected intestinal tube leaves two dead angles, which leaves the risk of intestinal leakage, and one closer is used, which causes waste of resources. Opening the intestinal tube again increases the chance of pollution in the abdominal cavity.

The utility model thoracoscope esophageal cancer surgery pouch forceps can complete the pouch through the minimally invasive surgical incision into the chest cavity, and then complete the esophageal cancer surgery through the laparoscope anastomat.

[0004] However, the above structure needs to be held throughout the clamping process, and the handle cannot be applied to the clamping forceps operation, so that full instrument operation cannot be realized, and the operation is not convenient. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a pouch forceps under endoscope, which solves the problem that the handle cannot be applied to the clamping forceps operation in the clamping process, so that full instrument operation cannot be realized, and the operation is not convenient.

[0006] In order to achieve the above object, the utility model provides a basic scheme: a purse forceps used under endoscope, including handle and two forceps head, the forceps head is equipped with forceps tooth, be equipped with needle eye on the forceps tooth its characterized in that, the handle includes first connecting rod, second connecting rod and torsion spring, the torsion spring end is connected with first connecting rod and second connecting rod respectively, first connecting rod and second connecting rod are welded on the side of forceps head respectively.

[0007] The principle and beneficial effects of the utility model lie in that: the maximum diameter of the whole purse forceps cross section is not more than 12mm, which can enter the abdominal cavity through the operation hole, the purse forceps is closed through the elastic force of the torsion spring, so when the forceps head reaches the occlusion position, the automatic occlusion can be achieved by releasing the clamping; the purse forceps does not need to be held during the operation process, which is convenient to operate, small in size and simple in shape, and is suitable for endoscopic minimally invasive surgery without expanding the wound.

[0008] Scheme two, this is the preferred of basic scheme, the forceps tooth is equipped with corrugated groove. The surface of intestinal tract in abdominal cavity is wet and slippery, the corrugated groove increases the friction force when the purse forceps occlusion, and the corrugated structure makes the contact surface smooth, so the abdominal cavity environment is not easy to scratch.

[0009] Scheme three, this is the preferred of basic scheme, the first connecting rod is equipped with guide groove, and the second connecting rod is slidably connected with the guide groove. The second connecting rod slides in the guide groove, so that the relative position of the first connecting rod and the second connecting rod does not deviate when the purse forceps opens or occlusion moves.

[0010] Scheme four, this is the preferred of basic scheme, the first connecting rod and the second connecting rod are equipped with positioning grooves at the ends. The positioning grooves are matched with the shape of the clamping part of the clamping forceps, which is used for assisting the positioning of the clamping forceps, and preventing the purse forceps from sliding off the clamping forceps.

[0011] Scheme five, this is the preferred of scheme four, the positioning groove is a internal hexagonal countersunk hole. The internal hexagonal hole positioning groove makes the clamping forceps can realize clamping at various angles, and when the clamping part of the clamping forceps falls into the countersunk hole, the positioning groove can be quickly found under the pressure, so the clamping part and the internal hexagonal hole do not need to be accurately aligned.
