An intelligent minimally invasive surgical instrument

Abstract

The invention discloses an intelligent minimally-invasive surgery instrument. The intelligent minimally-invasive surgery instrument comprises a handle drive device, an intermediate connecting device and a tail end execution device which are sequentially and fixedly connected. Handheld operation and motor drive are adopted, control signals are provided for the drive device through an operation control mechanism, the drive device drives the tail end execution device to move, and the tail end execution device outputs space multi-freedom-degree surgery motions. The defect that a traditional minimally-invasive surgery instrument is not flexible in operation is overcome, the defects that a surgery auxiliary robot device is expensive, high in maintenance and use cost, rigorous in operation technology requirement for doctors, different from doctor operation habits and the like are overcome, the intelligent minimally-invasive surgery instrument is in a new mode for replacing the traditional minimally-invasive surgery process with robot auxiliary minimally-invasive surgery, or the instrument is an electric intelligent endoscope surgery instrument, development potential is great, and the market prospect is wide.

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. Surgical robots are priced at RMB 20 million in China. 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. In addition, the operation method of robot-assisted surgery is quite different from that of traditional minimally invasive surgery. The operating habits of doctors must undergo long-term training to adapt to the operation method of robot-assisted surgery.
