Micro mechanical band for microsurgery

Abstract

A miniature manipulator for microsurgery is composed of a main body consisting of external and internal sleeve tubes, the first step motor at the tail end of said internal sleeve tube, the second step motor at the tail end of said external sleeve tube, the first position limiter on said external sleeve tube, a rotating mechanism on the output axle of the second step motor, a supporting tube extended from the front end of internal sleeve tube, an open-close mechanism on the output axle of the first step motor, a jaw-type forst tool exchanging unit in the front of said supporting tube, and the second position limiter.

Description

technical field [0001] The invention relates to a medical device, in particular to a component of the medical device used in microsurgery. Background technique [0002] In the early 1990s, the research and development of medical-surgical robots made great progress, and a number of research results were reported one after another. Microsurgery robotic hands are an important branch of medical-surgical robot research. At present, a small number of domestic scientific research institutes are carrying out research and development of microsurgery robotic hands. For example, the invention patent application with application number 03100038.x discloses a micro-mechanical hand for microsurgery, including a body, a fingertip replacement instrument, an instrument replacement mechanism, an instrument rotation mechanism, an instrument opening and closing mechanism, and an instrument limiting mechanism; The device limit mechanism includes a limit screw set ...
