Rapid replacing interface for assisted minimally invasive surgical operation robot

Abstract

The invention discloses a rapid replacing interface for an assisted minimally invasive surgical operation robot, which comprises a rapid replacing box part and a rapid replacing seat part, wherein the rapid replacing seat part is provided with an interface fixing seat; the rapid replacing box part comprises a box cover, a base connected with the box cover and a support plate which is arranged between the box cover and the base and connected with the base; a plurality revolving shafts arranged up and down are connected between the base and the support plate; a rotating shaft of a decelerator connected with an output shaft of an electric motor is installed in the position on the rapid replacing seat in the same axis with each revolving shaft; both sides of the base are provided with slide blocks; both sides of the interface fixing seat are provided with slide grooves, and the bottom of the interface fixing seat is provided with a limiting block; the slide blocks can be matched with the slide grooves up and down in a slide way; a positioning device of the rapid replacing seat and a rapid replacing box is arranged in the middle of the base along the horizontal direction; the end part of each revolving shaft is provided with a lug boss connected with a matching groove of a sleeve on the rotating shaft of the decelerator; and a photoelectric sensor sends a detected initial position signal to a controller of the electric motor. The interface has small volume and high rapid replacing efficiency.

Description

technical field [0001] The invention relates to a medical device in the field of minimally invasive surgery, which can quickly replace different surgical instruments and provide multiple degrees of freedom for the surgical instruments in the process of assisting minimally invasive surgical robot operations, especially relates to a A quick-change interface for an assisted minimally invasive surgical robot suitable for minimally invasive surgical operations in the thoracic and abdominal cavities. Background technique [0002] Minimally invasive surgery, represented by laparoscopy, is known as one of the important contributions of medical science to human civilization in the 20th century. Minimally invasive surgery refers to the use of long and thin surgical instruments to penetrate into the body through tiny incisions on the surface of the human body to perform surgery. operational. Compared with traditional open surgery, it has the advantages of small surgical incision, less...

Problems solved by technology

The disadvantage of this structure is that the structure is complex, and a first-level wire transmission is introduced between the motor and the drive shaft, which increases the friction of the transmission system. The layout of the support bearing at the rotation of the surgical instrument is equivalent to a cantilever beam, and the button is easily damaged and has a short service life.
