Problems solved by technology
However, for large perforation of the digestive tract such as gastric perforation, the jaws of ordinary grasping forceps are small, and it is often difficult to completely grasp the periphery of the perforation wound and gather them together; it is very difficult to use multiple clips at the same time, and the clips are easy to fall off , the success rate is also very low

Embodiment Construction
[0018] refer to figure 1 , an endoscopic grasper for closing digestive tract perforation includes a sheath 1 , a base 2 , a left clip assembly 3 and a right clip assembly 4 . The base 2 is fixed on the front end of the sheath tube 1 and has a fixed forceps head 21 extending forward. The left clamp assembly 3 includes a left clamp head 31, a left pulling wire 32 and a left handle 33. The left clamp head 31 is hinged on the base 2 and fits on the side of the fixed clamp head 21. The left handle 33 is arranged on the sheath 1 at the rear end, the left traction line 32 passes through the sheath tube 1 and connects the left forceps head 31 and the left handle 33, and the left handle 33 drives the left forceps head 31 to rotate relative to the base 2 through the left traction line 32, so that the left forceps head 31 and the fixed pliers head 21 are in an open or closed state. The right clamp assembly 4 includes a right clamp head 41 , a right pulling wire 42 and a right handle 43...

The invention discloses an endoscopic grasper for closing a digestive tract perforation. The endoscopic grasper for closing the digestive tract perforation comprises a sheath, a substrate and at least two pairs of side clamping assemblies. The substrate is fixed on the front end of the sheath, and the substrate extends forwards to form a fixing tong head. Each pair of the side clamping assemblies comprises a side tong head, a pull wire and a handle, wherein the side tong head is hinged to the substrate and matched with the side edge of the fixing tong head, the handle is arranged at the back end of the sheath, the pull wire penetrates through the sheath, and the sheath is connected with the side tong head and the handle. The handles drive the corresponding side tong heads to rotate relative to the substrate through the corresponding pull wires, so that the corresponding side tong heads and the fixing tong head are in an opening or closing state. The endoscopic grasper is used cooperatively with a pneumatic ligation device or a hemostatic clamp, the large perforation in the digestive tract can be gathered and closed, and the endoscopic grasper is convenient to operate.
Description
technical field [0001] The invention relates to medical device technology, in particular to an endoscopic grasping forceps used for closing huge wounds such as digestive tract perforation. Background technique [0002] Sutures are used in a variety of medical procedures involving joining two or more surfaces or edges together using repeated suture-type methods. For example, during digestive endoscopic surgery, clips can be used to fix the nylon loop around the perforation, and then tighten the nylon loop to suture the wound or connect the tissues. However, for large perforation of the digestive tract such as gastric perforation, the jaws of ordinary grasping forceps are small, and it is often difficult to completely grasp the periphery of the perforation wound and gather them together; it is very difficult to use multiple clips at the same time, and the clips are easy to fall off , the success rate is also very low. Contents of the invention [0003] The object of the pr...
