Abstract

The microtrauma operation cavity creating manipulator with four freedoms has one linear step motor set inside one hanging tub, connected to the lower hook and capable of moving along Z axis; one first decelerating step motor for driving the manipulator to move along X axis; one second decelerating step motor for driving the manipulator to move along Y axis; and one third decelerating step motor for driving the manipulator to move along Z axis. The present invention is used for hanging small cut to create cavity in microtrauma operation, can realize the flexible regulation of cavity space and four freedom motion.

Description

technical field [0001] The invention relates to a manipulator, in particular to a manipulator for minimally invasive surgery with four degrees of freedom. Background technique [0002] At present, many various medical robots have been developed at home and abroad, but there is no robot for automatic adjustment of cavity construction in minimally invasive surgery. Contents of the invention [0003] The purpose of the present invention is to provide a minimally invasive surgical cavity creation manipulator with four degrees of freedom. Using multiple degrees of freedom to adjust the cavity space, it is suitable for cavity construction in minimally invasive small incision surgery. [0004] In order to achieve the above object, the technical scheme adopted in the present invention comprises: [0005] 1) Put the linear stepping motor into the hanging bucket from the upper end of the hanging bucket, connect the linear stepping motor exposed at one end of the hanging bucket to ...
