Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing.

[0033] Such as figure 1 and 4 As shown, the present invention provides a multi-degree-of-freedom instrument connection mechanism for a surgical robot, which includes a rotation mechanism, a swing mechanism disposed in the rotation mechanism, and an opening and closing mechanism disposed in the swing mechanism, wherein the end of the swing mechanism They are respectively hinged to the rotating mechanism and the opening and closing mechanism, and the end of the opening and closing mechanism is provided with a multi-degree-of-freedom instrument 42 .

[0034] Specifically, the rotating mechanism is rotatably connected with the transmission seat 3, thereby realizing its rotation; the first end of the swing mechanism is hinged with the rotating mechanism, and the other end is fixedly connected with the first seat 35 slidably arranged on the transmission seat 3, thereby realizing...

Abstract

The invention relates to a multi-degree-of-freedom instrument connecting mechanism of a surgical robot, and relates to the technical field of surgical robots. In the prior art, the movements in multiple directions cannot be integrated. A purpose of the invention is to solve the problem in the prior art. The multi-degree-of-freedom instrument connecting mechanism comprises a rotating mechanism, a swinging mechanism and an opening-closing mechanism. According to the invention, through the rotating mechanism, the swinging mechanism and the opening-closing mechanism, the movement of the multi-degree-of-freedom instrument in three different directions can be achieved, so that the instrument connecting mechanism can simulate the arm rotation, the wrist rotation and the finger opening and closingmovement of a person so as to meet the requirements of a doctor on the degree of freedom, the flexibility and the sensitivity of the instrument in a complex operation; and the rotating mechanism, theswinging mechanism and the opening-closing mechanism are sequentially connected in a sleeved mode, so that the multi-degree-of-freedom instrument connecting mechanism is compact in structure, and therequirements of surgical instruments on small size and light weight are met.

Description

technical field [0001] The invention relates to the technical field of surgical robots, in particular to a multi-degree-of-freedom instrument connection mechanism of a surgical robot. Background technique [0002] On the basis of traditional surgery, minimally invasive surgery has been practiced and developed rapidly with many advantages such as fast postoperative recovery and small trauma. As a representative of minimally invasive laparoscopic minimally invasive surgery, it has become a major change in traditional open surgery. With the expansion of the field of minimally invasive surgery, the minimally invasive surgical robot system provides a new way to further improve minimally invasive surgery for the limitations of conventional endoscopic techniques in clinical applications. [0003] At present, the instruments used in the existing minimally invasive surgical robots only fix the instruments on the operating table through the connection mechanism, but cannot simulate t...
