Description

[Technical Field]

[0001] The present disclosure relates to the technical field of medical devices, and more particularly to a surgical system, a control method, and a surgical device having cavity dilation, cutting, and suction functions. [Background technology]

[0002] Before hysteroscopic surgery, the uterus is first infused with uterine expansion fluid to fill the uterine cavity and create a space for surgical manipulation and visualization. During surgery, intrauterine tumors and polyps are removed with a cutting handle, while waste fluid and tissue are simultaneously removed from the body using negative pressure suction.

[0004] Existing cutting, distension and suction integrated machines simply integrate these three functions, but there is no coordination or cooperation between the three functions, and doctors must manually control each function during use. Summary of the Invention

[0064] The present disclosure improves the automation level of the surgical system 1000 having cavity expansion, cutting, and suction functions by arranging a cavity expansion device 200, a cutting device 300, and a collection device 400 in the surgical system 1000 and controlling the cavity expansion device 200, the cutting device 300, and the collection device 400 with a single control device 100.

[0065] The controller 100 in the present disclosure may be implemented as either a single-chip microcomputer, a microcontroller unit (MCU), or any processor having computer program processing capabilities, and the present disclosure is not particularly limited as to the specific type or model of the controller 100.

[0066] FIG. 2 is a schematic diagram showing the overall structure of a surgical system according to an embodiment of the present disclosure.

The second microswitch 2053 generates a second trigger signal when the transport pipeline 204 is completely installed between the first wall A and the second wall B, and transmits the second trigger signal to the controller 100.

[0089] By arranging the first microswitch 2021 and the second microswitch 2053, the cavity expansion device 200 can detect in real time the placement status of the transport pipeline 204, i.e., whether the first pump device 202 and the pressure chamber 2051 have been installed.
