Abstract

Disclosed is a single-port endoscopic surgical system, comprising a flexible surgical instrument (10), an imaging tool (30) and catheter bodies (40, 50). The flexible surgical instrument (10) comprises a surgical executor (101), a flexible arm body (11), a handle (21) and a proximal structural body (16), the surgical executor (101) being linked to a distal end of the flexible arm body (11), a proximal end of the flexible arm body (11) being linked to the handle (21) through the proximal structural body (16), and the handle (21) driving the flexible arm body (11) to perform a turning motion. The imaging tool (30) comprises an imaging illumination module (301), a turning joint (302) and an imaging tool driving unit (304), the imaging illumination module (301) being linked to a distal end of the turning joint (302), a proximal end of the turning joint (302) being linked to the imaging tool driving unit (304), and the imaging tool driving unit (304) driving the turning joint (302) to perform a turning motion. The catheter bodies (40, 50) are used for guiding the surgical executor (101) at the distal end of the flexible arm body (11) and the imaging illumination module (301) at the distal end of the turning joint (302) to the same region, and simultaneously guiding parts located behind the proximal ends of the flexible arm body (11) and the turning joint (302) in spatially different directions.

Description

technical field [0001] The invention relates to a medical device, in particular to a single-hole endoscopic surgery system based on a flexible surgical tool. Background technique [0002] In the modern medical field, manual porous laparoscopic minimally invasive surgery has been widely used clinically. Such minimally invasive procedures have successfully reduced patients' postoperative pain, complication rates, recovery time, and improved postoperative scarring. In recent years, in order to facilitate doctors' operation and achieve better postoperative output, robot-assisted porous laparoscopic minimally invasive surgery has been widely used. The robotic system, which can assist doctors in performing multi-hole laparoscopic minimally invasive surgery, has achieved great commercial success. [0003] In order to further reduce the surgical trauma area and recovery time, researchers proposed single-port laparoscopic minimally invasive surgery. Compared with multi-hole laparo...
