Abstract

The invention relates to a flexible surgical tool system using structure bones. The flexible surgical tool system comprises a flexible connecting body structure consisting of a remote end structure body, a middle part connecting body and a near end structure body which are associated in sequence. The flexible surgical tool system is characterized by also comprising a transmission driving unit associated with the near end structure body; the transmission driving unit comprises a plurality of transmission mechanisms respectively and correspondingly driving the near end structure joints; the transmission mechanisms can convert the pair of axial line parallel rotation motion inputs into a pair of axial line vertically intersectant rotation motion outputs, wherein one rotation motion output parallel to the rotation motion input axial line is used for controlling the curving plane pointing direction of the near end structure joints; the other rotation motion output vertical to the rotation motion axial line is used for controlling the curving angle of the near end structure joints in the curving plane, so that the near end structure joints in the near end structure body are driven to curve in any direction; and associated remote end structure joints in the remote end structure body are further driven to curve in an opposite direction.

Description

technical field [0001] The invention relates to a medical device, in particular to a flexible surgical tool system using structural bone. 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 lighting module...
