Aseptic separator and surgically assisted robot instrument system

Abstract

The invention discloses an aseptic separator. The aseptic separator includes upper partition plates connected to an instrument box and lower partition plates connected to power units; each upper partition plates and one corresponding lower partition plate are provided with a hollow cavity for accommodating a transition flange; each transition flange is arranged in one corresponding hollow cavity;the inner diameter of each hollow cavity is greater than the outer diameter of one corresponding transition flange; the part, located at the upper end of one corresponding hollow cavity, of each upperpartition plate is provided with a first limit boss; the part, located at the lower end of one corresponding hollow cavity, of each lower partition plate is provided with a second limit boss; the outer surface of each transition flange is provided with a third limit boss corresponding to one first limit boss and one second limit boss; a gap where a sterile cover is arranged is arranged between the upper partition plates and the lower partition plates; and each upper partition plate is fixedly connected with one corresponding lower partition plate by screws. The aseptic separator provides mechanical conditions for realization of force feedback, realizes intuitive operation, greatly increases the safety performance of surgical operation, and has improved overall safety performance.

Description

technical field [0001] The present invention relates to a divider for distinguishing power and instruments of a surgical assisting robot. 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 the whole process of...

Problems solved by technology

However, in the prior art, because there are too many transmission links of the instrument and the transmission distance is long, there are many friction points in the transmission, which makes it difficult to feed back the force on the end of the instrument to the doctor during the operation.

[0004] According to the specific conditions of the operation, it is necessary to use instruments with different claw structures for the operation, but the instruments and power systems in the prior art are all of an integral structure, which is very inconvenient to install and disassemble

And the power system part is easy to moisten bacteria, thus increasing the risk of infection for patients
