Mechanical arm layout structure of minimally invasive surgical robot

Abstract

The invention discloses a mechanical arm layout structure of a minimally invasive surgical robot. The mechanical arm layout structure comprises a base, a stand column, a top platform, an adjusting main arm and adjusting branch arms. The adjusting main arm is mounted on a joint of the top platform; the adjusting branch arms are mounted on the adjusting main arm; each adjusting branch arm comprises a plurality of operation arm sections and a connecting base which are sequentially connected in series, the adjacent arm sections are connected through rotating joints or moving joints, the arm sections and the connecting bases are connected through rotating joints or moving joints, each connecting base is connected with a quick connector, and an endoscope or surgical tool is installed on each quick connector. An operation arm I, an operation arm II and an operation arm III of each adjusting branch arm are adjusted to achieve rapid positioning of the position where the surgical instrument extends into the wound, on the basis, an operation arm IV, an operation arm V and an operation arm VI corresponding to each adjusting branch arm are adjusted to achieve rotation of the arm rod of the surgical instrument around the wound position, and finally the arm rod extends into the wound at a proper angle.

Description

technical field [0001] The invention relates to the technical field of minimally invasive surgical robots, in particular to a layout structure of a mechanical arm of a minimally invasive surgical robot. Background technique [0002] Minimally invasive surgery means that doctors use long and thin surgical tools to penetrate into the body through tiny incisions on the surface of the human body for surgical operations; compared with traditional open surgery, it has small surgical incisions, less bleeding, small postoperative scars, and faster recovery. The time is fast and other advantages, which greatly reduces the pain suffered by the patient. [0003] Minimally invasive surgery can bring many benefits to patients, but it adds a series of difficulties to the operation of doctors. Doctors must undergo long-term training before they can perform minimally invasive surgery. The surgical robot system can assist doctors and expand their capabilities. More flexibility, safety and r...

Problems solved by technology

[0004] Minimally invasive surgical robots are high-tech intensive high-end precision medical equipment. There is no self-produced minimally invasive surgical robot system that can be clinically applied in the Chinese market. Existing foreign minimally invasive surgical robots have layout flexibility in the overall structure There are still some deficiencies in the balance of force and force, as well as the efficiency of preoperative planning and layout
