Mechanical arm connecting device for surgical robot and surgical robot

Abstract

The invention relates to a surgical robot and a mechanical arm connecting device for the surgical robot. The mechanical arm connecting device comprises a first pipe section and a second pipe section. The center axis of the first pipe section is perpendicular to the center axis of the second pipe section. A first flange plate is arranged at one end of the first pipe section, the other end of the first pipe section is perpendicularly connected with one end of the second pipe section, and a second flange plate is arranged at the other end of the second pipe section. The first flange plate is connected with a stand column of the surgical robot. The second flange plate is connected with a mechanical arm of the surgical robot. The mechanical arm connecting device allows the mechanical arm to move forwards, leftwards and rightwards within a wider range and larger space, and facilitates positioning of the mechanical arm before surgery, so that larger surgical space can be obtained. Mechanical arms can be installed on all four sides of the stand column, both independent use of one mechanical arm and simultaneous use of two, three or four mechanical arms can be achieved, and surgical requirements with different installation demands are met through various combinations of mechanical arms in different positions.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a connecting device for a mechanical arm of a surgical robot capable of obtaining a larger operating space and a surgical robot with a connecting structure for the mechanical arm. Background technique [0002] Among the numerous medical devices, various surgical robots are being used more and more widely in the medical field. As an important part of the medical device field, surgical robots have been widely used in many operating rooms around the world, such as cardiothoracic surgery, urology, gynecology and abdominal surgery. At the same time, with the rapid development of computer and microelectronic technology and medical science, a large number of medical devices have been promoted and applied. These robots provide powerful assistance in surgery with the support of computers and microelectronics. In addition, these machines also need surgeons to operate ...

Problems solved by technology

However, while minimally invasive surgery has brought many benefits to the patient, it has brought a series of difficulties to the doctor's operation, such as: due to the limitation of small holes on the body surface, the degrees of freedom of the tool are reduced to four, and the flexibility is greatly reduced The direction of the doctor's operation is opposite to the expected direction, and the coordination is poor; the doctor can only obtain the information of the surgical scene through the two-dimensional image on the monitor, and lacks the feeling in the depth direction; the shaking of the doctor's hand may be affected by the slender surgical tool Magnification, adversely affecting surgery; lack of force sensation

Therefore, doctors must undergo long-term training before they can perform minimally invasive surgery. Even so, minimally invasive surgery is currently only used in relatively simple operations.
