[0002] Laparoscope is an instrument with a miniature camera. Laparoscopic surgery is a surgery performed using a laparoscope and its related instruments. During surgery, the laparoscope lens (3-10mm in diameter) is inserted into the abdominal cavity. The image captured by the laparoscope lens is transmitted to the back-end signal processing system through optical fibers using digital camera technology, and is displayed on the monitor in real time. The doctor then analyzes and judges the patient's condition through images of the patient's organs from different angles displayed on the monitor screen, and performs the surgery using special laparoscopic surgical instruments.

[0003] Patent CN220876940U discloses a laparoscopic surgical instrument fixing device, which belongs to the field of surgical instrument technology.

In the laparoscopic surgical instrument fixing device, the lifting rod can slide inside the support frame to adjust the height of the lifting rod, and the extension height of the lifting rod can be adjusted according to the height, so that the adjusting rod can be adjusted within the fixed shaft, and a certain angle can be adjusted according to demand, and the corresponding angle can be adjusted by rotating the gripper, so that the gripper drives the movable shaft to adjust the angle, and the movable shaft can adjust the angle inside the adjusting shaft, which can be used according to demand.

[0004] As in the above-mentioned patent, although various adjustment rods are movably connected through a series of adjustment shafts to achieve the fixed and adjustable function of the laparoscope, multiple knobs must be rotated to adjust to the desired angle during adjustment, which is very inconvenient to operate and difficult to adjust quickly and efficiently. Moreover, with the existing device, it is difficult for an assistant to adjust the angle while standing in one position, and the assistant will still occupy a certain amount of space during the adjustment process. In addition, the device itself is fixed on the side of the bed and will also take up some space, which will always cause certain obstacles to the surgeon and is not practical enough.
