Abstract

The invention relates to a flexible surgical tool system. The flexible surgical tool system comprises a mechanical arm, a surgical actuator and a transmission drive unit. The mechanical arm comprisesa first continuum structural section, a rigid connection structural section and a second continuum structural section. The first continuum structural section, the rigid connection structural section and the second continuum structural section are sequentially associated to form a dual continuum mechanism. The surgical actuator is connected to the far end of the second continuum structural section.The transmission drive unit is associated with the rigid connection structural section and the surgical actuator and used for driving the first continuum structural section to turn in any direction,then driving the second continuum structural section to turn in the opposite direction in a coupled manner, and driving the surgical actuator to complete rotational movement in the first plane and/oropening and closing movement in the second plane. The flexible surgical tool system can be well applied to performing surgery through natural orifices of the human body or a single surgical incision.

Description

technical field [0001] The invention relates to a medical device, in particular to a flexible surgical tool system based on a dual continuum mechanism. Background technique [0002] Porous laparoscopic minimally invasive surgery has occupied an important position in surgical operations because of its small incision and fast postoperative recovery. The da Vinci (Da Vinci) surgical robot of the existing Intuitive Surgical Company (American Intuitive Surgical Company) assists doctors in completing multi-hole laparoscopic minimally invasive surgery, and has achieved great commercial success. [0003] After multi-port laparoscopic surgery, minimally invasive surgery has developed single-port laparoscopic surgery and non-invasive surgery through natural orifice, which are less invasive to patients and have higher postoperative output. However, in single-port laparoscopic surgery and non-invasive surgery through the natural orifice, all surgical instruments, including the visual l...
