Intelligent instrument for minimally invasive surgery

Abstract

The invention discloses an intelligent instrument for minimally invasive surgery. The intelligent instrument comprises a handle drive device, a middle connecting device, a tail end executing device and a tail end moving joint part. The handle drive device comprises a handle, the rear end of the handle is rotationally connected with one end of a handle connecting rod through a first bearing, and the handle is connected with a deflection potentiometer. An opening and closing mechanism is arranged at the front end of the handle, a self-rotation base is rotationally connected with the handle and connected with a self-rotation potentiometer, two opening and closing clacks are used for achieving the opening and closing movement, and the movement is output to the tail end moving joint part through the motor and a transmission structure. The device is operated through instinct, equipment cost is low, the maintaining and using cost is high, the operation technique requirement for doctors is low, and the operation of the intelligent instrument is the same as the operation habit of the doctors.

Description

technical field [0001] The invention relates to a minimally invasive surgical medical device, in particular to a hand-held intelligent surgical instrument. Background technique [0002] During robot-assisted minimally invasive surgery, doctors perform surgical tasks with the help of slender minimally invasive surgical instruments. One end of the surgical instrument is placed on the quick-change interface device at the end of the robot's operator's hand, and the other end is inserted into the body through a tiny incision on the surface of the human body for surgical operations. Therefore, the surgical instrument is the only part in contact with the human diseased tissue. It is also the part of the robot that directly performs the surgical operation. In the implementation of surgery, in order to meet the action requirements of different surgical operation tasks (clamping, suturing, knotting, etc.), the robot should replace the instruments that match the requirements at any ti...

Problems solved by technology

[0003] However, the popularization of robot-assisted minimally invasive surgery technology is not achieved overnight. Some factors limit the popularization of robot-assisted minimally invasive surgery technology. The price of a surgical robot in China is 20 million yuan. The high cost of equipment makes it impossible for most hospitals to purchase surgical robots or patients cannot afford the high cost of surgery; doctors who perform robot-assisted minimally invasive surgery need to undergo strict and systematic training , and the operation method of robot-assisted surgery is quite different from that of traditional minimally invasive surgery. The doctor's operating habits must undergo long-term training to adapt to the operation method of robot-assisted surgery.
