Problems solved by technology

[0002] In minimally invasive surgery, doctors often need to manually cut, strip, and suture tissues. For some complicated surgical operations, doctors need to stand for a long time and hold micro-surgical instruments for surgery. Doctors are prone to fatigue, which affects the operation. quality
At the same time, conventional minimally invasive surgical instruments are simple imitations of traditional open surgical instruments, with less freedom, low flexibility, and high internal friction, which will lead to attenuation of transmission force and fatigue of doctors, making it difficult to avoid hand tremors, The accuracy of the operation is reduced due to fatigue, which is not convenient for the smooth operation of the operation
[0003] At present, robot-assisted minimally invasive surgery is gradually applied to actual clinical practice. Some of these robot-assisted surgery have a low degree of freedom. For example, when performing more complex minimally invasive surgery, doctors cannot The requirements for the degree of freedom, flexibility and sensitivity of surgical instruments, so there is a technical problem of inflexibility in robotic surgical operations in the prior art

Abstract

The application provides a surgical robot. The surgical robot comprises a push handle, a trolley, mechanical arms, surgical instrument assemblies and slipways used for connecting the mechanical arms with the surgical instrument assemblies correspondingly; each surgical instrument assembly includes an instrument fixing device and a surgical instrument; each slipway includes a limiting assembly usedfor limiting the moving range of the corresponding surgical instrument in a slipway direction; and each surgical instrument can do opening-closing movement. The rectilinear movement of each surgicalinstrument along the corresponding slipway can be limited through the corresponding limiting assembly, so that the situation that each surgical instrument moves to a limit position is prevented to lower the risk of damage; and each surgical instrument of the surgical robot can do deflection movement and the opening-closing movement, and thereby, the freedom degree and the flexibility of each surgical instrument are increased, and control of a doctor is more facilitated to perform surgery.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical robot. Background technique [0002] In minimally invasive surgery, doctors often need to manually cut, strip, and suture tissues. For some complicated surgical operations, doctors need to stand for a long time and hold micro-surgical instruments for surgery. Doctors are prone to fatigue, which affects the operation. quality. At the same time, conventional minimally invasive surgical instruments are simple imitations of traditional open surgical instruments, with less freedom, low flexibility, and high internal friction, which will lead to attenuation of transmission force and fatigue of doctors, making it difficult to avoid hand tremors, The reduction of the accuracy of the operation caused by fatigue is not convenient for the smooth operation of the operation. [0003] At present, robot-assisted minimally invasive surgery is gradually applied to actual ...
