[0002] A laparoscopic trocar is a surgical instrument that cooperates with minimally invasive equipment and provides an instrument channel for minimally invasive abdominal and pelvic surgeries. When in use, the extraction cylinder needs to be inserted into the insertion cylinder, and then the staff inserts both into the abdominal cavity of the examinee, and then the extraction cylinder is withdrawn from the insertion cylinder.

[0003] Such as the Chinese patent: "CN219354095U", the technical solution disclosed by this patent is as follows: It discloses a laparoscopic trocar, belonging to the field of trocars, including a puncture cannula. A puncture needle is movably installed inside the puncture cannula. An air injection valve is fixedly installed on one side of the puncture cannula, and a support mechanism is fixedly installed on the other side of the puncture cannula. The support mechanism includes a support rod, a storage tube, a rotating ring, an arc rod, a screw rod, a first movable tube, a pressing table, a second movable tube, and a fixed table. The support rod is located on the side of the puncture cannula. The first movable tube is located outside one of the storage tubes, and the second movable tube is located outside the other storage tube. Through the set support structure, the arc rod rotates upward inside the storage tube, thus supporting the head position of the puncture cannula. The screw rod is moved downward movably, so as to mutually support with the edge position of the external abdomen or the operating table, thereby providing an external support force for the puncture cannula, making the stability better, the surgical channel more stable, and facilitating surgical operations.
