Multi-degree-of-freedom multifunctional operation mechanical hand

Abstract

The invention discloses a multi-degree-of-freedom multifunctional operation mechanical hand which comprises three seven-degree-of-freedom mechanical arms with the tail ends provided with front end tool joints. The seven degrees of freedom of the seven-degree-of-freedom mechanical arms are the degree of freedom for rotating around the center axis of the arms, the degree of freedom for stretching back and forth from the arms, the degree of freedom for horizontal swinging, the degree of freedom for vertical swinging, the degree of freedom for horizontal swinging, the degree of freedom for vertical swinging and the degree of freedom for a tool in sequence from bottom to top, after the second degree of freedom from the lower end, and the other five degrees of freedom are completed inside a mechanical arm installation piece. The mechanical hand is reasonable in design, capable of achieving operation procedures such as cutting, pulling, suturing and the like, and therefore the operation operability and accuracy are improved. The mechanical hand is applicable to neurosurgical and most surgical and thoracic and celiac surgery; except for operative instrument replacement, other operations can be controlled by a computer, the precision is higher, and the phenomenon that misoperation is caused due to the fact that doctors are too tied during operation is avoided.

Description

technical field [0001] The invention relates to a medical surgical instrument, in particular to a multi-degree-of-freedom multifunctional surgical manipulator. Background technique [0002] A manipulator is an automatic operating device that can imitate certain movement functions of the human hand and arm to grab, carry objects or operate tools according to a fixed program. The feature is that various expected operations can be completed through programming, and the structure and performance have both the advantages of man and robot. [0003] The manipulator is the earliest industrial robot and the first modern robot. It can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, it is widely used in machinery manufacturing, metallurgy, Departments of electronics, light industry and atomic energy. [0004] In today's life, with the rapid development of scienc...

AI Technical Summary

Problems solved by technology

However, the existing medical manipulators still have the following disadvantages: At present, there are only surgical manipulators used in the abdominal cavity or thoracic cavity, and there is no manipulator suitable for neurosurgery; secondly, the manipulator has limited freedom of movement, and cannot achieve the in-cranial manipulator required by neurosurgery. The precision of mental operations

The doctor will be very tired before the operation is completed, which will affect the progress of the operation

Although there are manipulators for thoracoabdominal surgery at present, their operational flexibility, functionality and accuracy are still far from the requirements of neurosurgery. More importantly, there is no manipulator for neurosurgery.
