Description
Technical Field

Surgical robots are used in the field of minimally invasive surgery that is beyond human capabilities, to achieve precision operations that cannot be completed by human capabilities alone. Laparoscopic surgical robots usually consist of a surgical console, a surgical cart equipped with a robotic arm, and a video system.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0028] Example 1
[0029] See attached Figure 1-7This embodiment discloses a tumor ablation cutting surgical robot system, including a main console 1, a video imaging system and a robotic arm system. The video imaging system and the robotic arm system are both electrically connected to the main console 1. The main console 1 is used for medical staff to operate the robot, the video imaging system is used for imaging the surgical site, and the robotic arm system is used to perform the operation.
[0030] Specifically, the robot system includes a control frame 2, a robot arm 3, a serpentine joint tube 4 and a cutting head 5. The robot arm 3 is provided with a plurality of degrees of freedom. The plurality of robot arms 3 are arranged on the control frame 2. The cutting head 5 and the visual monitoring unit 6 are arranged at the end of the robot arm 3 through the serpentine joint tube 4. The cutting head 5 includes a sleeve 501, a microwave knife 502, a water inlet pipe and a negative pressure water suction pipe 503. A solid filler 511 is arranged in the sleeve 501. In this embodiment, protective plates are respectively arranged on both sides of the front end of the sleeve 501. The protective plates are the front of the sleeve 501. The two protrusions left after digging out the two U-shaped grooves, the front end of the microwave knife 502 is provided with an arc-shaped cutting edge, the microwave knife 502 is arranged at the front end of the sleeve 501 through the solid filler 511, and is used to cauterize the tissue around the incision to stop bleeding, the front end of the microwave knife 502 is provided with a water outlet 504 and a water suction port 505, the water inlet pipe is arranged on one side of the arc-shaped cutting edge of the microwave knife 502, and is connected to the water outlet 504, and is used to flush the tissue; the negative pressure water suction pipe 503 is arranged on the other side of the microwave knife 502, and is connected to the water suction port 505, and is used to suck away blood.
[0031] The water inlet pipe includes a first water inlet pipe 405, a second water inlet pipe and a water volume regulating mechanism. The first end of the first water inlet pipe 405 is connected to an external water source, the first end of the second water inlet pipe is connected to a water outlet 504, the first end of the water volume regulating mechanism is connected to the second end of the first water inlet pipe 405, the second end of the water volume regulating mechanism is connected to the second end of the second water inlet pipe, and the water volume regulating mechanism is electrically connected to the main control console 1.
[0032] The second water inlet pipe includes an accelerating water inlet pipe 506 and a decelerating water inlet pipe 507 arranged side by side. The first end of the accelerating water inlet pipe 506 and the first end of the decelerating water inlet pipe 507 are both connected to the water outlet 504, and the second end of the accelerating water inlet pipe 506 and the second end of the decelerating water inlet pipe 507 are both connected to the water volume regulating mechanism.

[0033] In this embodiment, the accelerating water inlet pipe 506 has a tapered structure, and a spiral channel connected to the accelerating water inlet pipe 506 is circumferentially arranged. The cutout of the spiral channel is located on the side away from the center of the accelerating water inlet pipe 506.

[0040] The serpentine joint tube 4 includes a flexible inner support tube 401 and a plurality of connecting tube monomers 402 fixed at intervals on the flexible inner support tube 401. The front end of the flexible inner support tube 401 is fixedly connected to the sleeve 501, and the rear end is fixedly connected to the robotic arm 3. The front end of the connecting tube monomer 402 and the front end of the robotic arm 3 are symmetrically provided with two smooth lugs, and the rear end of the connecting tube monomer 402 and the rear end of the sleeve 501 are symmetrically provided with two smooth grooves matching the smooth lugs. The connecting line of the two smooth lugs on the same connecting tube monomer 402 is perpendicular to the connecting line of the two smooth grooves. The sleeve 501 and the connecting tube monomer 402, between two adjacent connecting tube monomers 402, and between the connecting tube monomer 402 and the robotic arm 3 are all spliced with each other through smooth lugs and smooth grooves.

The specific structure of the serpentine joint tube and the pulling wire device can refer to the serpentine tube joint structure and wire drive carrier module in the Chinese invention patent with publication number CN114587600A. By controlling the pulling wire device to pull the corresponding traction rope 403, the serpentine joint tube 4 is bent according to the length change of the traction rope 403 in this direction, thereby driving the surgical cutting head at its front end to adjust to a suitable angle.
[0042] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
