Embodiment Construction

[0089] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0090] Such as Figure 1 to Figure 35 As shown, a surgical assisting robot instrument system includes a power part 100 , a sterile divider 200 and an instrument 300 .

[0091] In this embodiment, the power unit includes four power groups, and the four power groups 101 are parallel in a rectangular shape. In other specific embodiments, the number of power groups can be set according to specific needs, such as the number of operating degrees of freedom of the claws of the instrument. Of course, only one power group can also be provided to achieve the purpose of controlling the movement of the claws of the instrument through one or more outputs of the transmission part.

[0092] Such as Figure 1 to Figure 3 As shown, the four power groups all include motors 101, and each motor 101 is connected to a reducer 102, and a telescopic output flange 104 is sleeved o...

Abstract

The present invention discloses a surgical auxiliary robot instrument system. The surgical auxiliary robot instrument system comprises a power part, a sterile separator and an instrument, and the power part comprises at least one power group; each power group comprises a motor; each motor is connected with a speed reducer; an output shaft of each speed reducer is sleeved with a telescopic output flange; each output flange can be in inserted connection with a transition flange of the sterile separator; each transition flange can be in inserted connection with an input flange of the instrument;and the number and the positions of the output flanges, the transition flanges and the input flanges are corresponding. The surgical auxiliary robot instrument system provides mechanical conditions for realizing force feedback, realizes direct-sensing operation, greatly improves safety performance of surgical operations, also improves overall safety performance of the device, and is good in stability, high in motion precision, high in mechanism reliability, simple and convenient in operation, simple in manufacture and convenient in maintenance.

Description

technical field [0001] The invention relates to a driving structure, in particular to a driving structure for a surgical operation auxiliary robot instrument. Background technique [0002] A medical robot for minimally invasive surgery performs surgical operations on patients through instruments fixed at the end of the robot joint, such as the laparoscopic surgery robot disclosed in CN107951565A. Specifically, the claws of the instrument are parts such as clamps or scissors, and these parts are controlled and operated by wires. Due to the specific structure of the robot and the characteristics of the operation, the claws of these instruments need to be arranged at the end of a slender rod, and the steel wires controlling the claws pass through the cavity of the slender rod. [0003] During the operation, the front part of the long rod goes deep into the patient's abdominal cavity to perform the operation. Therefore, this requires the doctor to be able to accurately perceive...
