[0030] In this embodiment, a rotating wheel 13 is mounted on the shell 3, and the rotating wheel 13 is provided with a rotating part. The first rack 11 is mounted on the left side of the rotating part of the rotating wheel 13, and the second rack 12 is mounted on the right side of the rotating part of the rotating wheel 13. The guide mechanism 2 includes a snake tube. The principle structure of the snake tube is a pipeline structure, which is composed of a plurality of interconnected and retractable pipe segments.

The first rack 11 is connected to the guide mechanism 2 by a steel wire rope, and the second rack 12 is connected to the guide mechanism 2 by a steel wire rope. The probe 4 includes an ultrasonic probe 4 for detecting and generating images.

[0031] The working process of the laparoscope is as follows:

[0032] The rotating wheel 13 rotates counterclockwise to drive the first rack 11 to move downward, and drives the second rack 12 to move upward, and then drives the guide mechanism 2 to bend to the left through the wire rope. The rotating wheel 13 rotates clockwise to drive the first rack 11 to move upward, and drives the second rack 12 to move downward, and then drives the guide mechanism 2 to bend to the right through the wire rope.

[0033] By turning the rotating wheel 13, the bending of the guide mechanism 2 can be controlled, thereby driving the probe 4 to penetrate into the cavity. The connection structure of the rotating wheel 13, the wire rope and the guide mechanism 2 is simple, and the bending angle of the guide mechanism 2 can be finely adjusted by adjusting the rotating wheel 13.
