[0025] 1. The laparoscope with a sheathed abdominal wall anastomat is reasonable in design and comprises a puncture device and an abdominal wall suture device. When wound suturing is needed, the puncture cone assembly is only inserted into the puncture sleeve assembly, and then the abdominal wall suture device can be used to bring the suture into the body through the guide hole of the puncture device, perform deep fascia suture, and pull out the suture on both sides of the incision outside the puncture sleeve to knot, without affecting the operation. Since the puncture sleeve assembly has isolated the wound tissue, the subsequent insertion of the puncture cone assembly will not stimulate the wound, reducing the pain of the patient.

[0026] 2. The puncture device in the laparoscope with a sheathed abdominal wall anastomat is compact in overall structure and reasonable in design. The multi-flap structure makes the insertion of the device more smooth, and has good sealing performance. The inside of the one-piece cap is provided with a cross structure, which will protrude outward due to the gas pressure when gas is supplied into the puncture device, preventing the leakage of abdominal cavity gas and maintaining stable gas pressure. The top of the puncture sleeve assembly is provided with a detachable structure, which can be easily removed to take out larger tissues. It has the functions of ordinary puncture devices and can be used with the abdominal wall suture device to perform puncture incision suturing.

[0027] 3、The abdominal wall suture device in the laparoscope with sheath abdominal wall anastomat is designed with exquisite and reasonable structure. The surgeon can easily and automatically grab the suture line in the operation of closing the surgical incision, and it is not easy to fall off, thereby ensuring the safety of the operation.

[0059] The working principle of the above-mentioned laparoscopic abdominal wall anastomosis device with sheath is as follows:

[0060] 1. Insert the puncture cone 2-4 of the puncture cone assembly 2 into the puncture cannula assembly 1. The release switch 2-2 of the puncture cone assembly 2 is engaged in the groove at the top of the puncture cannula assembly 1. The puncture cone head 2-5 at the lower end of the puncture cone 2-2 is fully exposed at the front end of the puncture cannula 1-4. The guide hole 1-12 is connected to the guide hole 3-5, and the guide hole 2-13 is connected to the guide hole 4-6, so as to facilitate the insertion of the abdominal wall suture device 3 for threading and hooking the suture.

[0061] 2. Using standard surgical procedures, make a skin incision in the abdominal cavity large enough to accommodate the size of the trocar.

[0062] 3. Insert the trocar assembly 1 and trocar assembly 2 into the skin incision. During puncture, place the tip of trocar assembly 2 in the palm of your hand, place two fingers on either side of the cannula seat 1-7, and grip firmly to perform puncture. Do not use excessive force during puncture to avoid damaging abdominal organs.

[0063] 4. After the puncture is completed, press the release switch 2-2 on the puncture cone assembly 2 to pull the puncture cone assembly 2 out of the puncture cannula assembly 1. Connect the pneumoperitoneum machine interface to the insufflation valve 1-10, tighten the connector to prevent air leakage, open the insufflation switch 1-9, and inject carbon dioxide gas into the abdominal cavity through the puncture cannula assembly 1. Then, the surgical operation can be performed with the assistance of the endoscope.

[0064] 5. After the surgical procedure, reinsert the puncture cone assembly 2 into the puncture cannula assembly 1 to assemble the trocar. Pull the trocar partially out of the abdominal cavity, positioning the guide holes 1-12 and 2-5 at the upper end of the trocar close to the external abdominal wall. Press down the push handle 3-1 of the abdominal wall suture device 3 to expose the pull hook 3-6. Place a strand of suture into the suture clamp 3-7 of the pull hook 3-6, and release the push handle 3-1 to retrieve the suture. Position the inverted triangle pattern on one side of the handle 3-4 of the abdominal wall suture device 3 towards the outside of the puncture cannula. Then, insert the abdominal wall suture device 3 carrying the suture obliquely through the guide hole 1-12 on the puncture cannula assembly 1 into the guide hole 2-5 on the puncture cone assembly 2, and then sequentially through the guide hole 4-5 on the puncture cone assembly 2 and the guide hole 2-13 on the puncture cannula assembly 1 to penetrate into the abdominal cavity. Press the push handle 3-1 to release the suture clamp 3-7 from the sleeve 3-5, loosen the suture, and then pull out the abdominal wall suture device 3.

[0065] 6. Insert the abdominal wall suture device 3 through the guide hole 1-12 on the other side of the trocar assembly 1, then sequentially through guide holes 2-5, 2-6, and 1-13 into the abdominal cavity. Grasp the suture ends previously left inside the body and pull them out, ensuring both ends of the suture are outside the body. The entire procedure is performed with the assistance of a laparoscope. After completing the surgical procedure, gently remove the trocar, and finally tie a knot according to the surgeon's technique to complete the fascia suture.
