Novel minimally invasive surgical instrument control device based on flexible wire transmission

Abstract

The invention provides a novel minimally invasive surgical instrument control device based on flexible wire transmission, which comprises a fixing component (1), a drivingcomponent (2), a mechanical arm component (3) and an end actuator (4).The fixing component comprises a wrist support and a shell; the driving component comprises a hand-held frame, a connecting belt, a driving pulley, a reversingroller, a cable and the like; the mechanical arm component comprises a bent rod and a straight rod; the end actuator includes a joint, a spring, etc. A doctor drives the driving pulley to rotate by holding the hand-held frame, so that the wound cable is subjected to displacement change, so that the end actuator generates corresponding response to the instruction sent by the doctor. According to the minimally invasive surgical instrument, the arm and the wrist-shaped control can be realized easily and intuitively, the rotation of any angle in the human body can be realized, the structure is simple and unique, the cost is low, the practicability is strong, the working efficiency is high, and the requirements of the surgical doctor on the minimally invasive surgical instrument can be met.

Description

technical field [0001] The invention belongs to the technical field of minimally invasive surgical auxiliary equipment, and in particular relates to a control device for a novel minimally invasive surgical instrument. Background technique [0002] Minimally invasive surgery, as the name suggests, is surgery with minimal trauma. The patient does not need an operation, but only needs to make 1-3 small holes of 0.5-1 cm in the body, and all subsequent operations will be carried out through these channels; and then the same steps as open surgery will be completed under image monitoring with special lengthened surgical instruments. This surgical treatment method has the advantages of less bleeding, less trauma, less complications, safety and reliability, and quick postoperative recovery. It greatly reduces the damage to the human body caused by traditional surgery, and reduces the inconvenience and pain caused by diseases to patients. [0003] Since minimally invasive surgery is...

AI Technical Summary

Problems solved by technology

However, the current minimally invasive surgical instruments are bulky, complicated to operate, and costly

As far as the well-known Da Vinci medical surgical robot system is concerned, it is very troublesome to operate, and the operation time is long, which directly affects the efficiency of the operation. Moreover, the entire surgical auxiliary system is very expensive, making it very expensive in the hospital. greatly reduced popularity

Secondly, the reliability of the operation is often difficult to guarantee for cheaper instruments, which pose a serious threat to the life safety of patients.
