Embodiment Construction

[0013] A micromanipulator for throat surgery of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Such as figure 1 As shown, a micromanipulator for throat surgery of the present invention includes a body 30, a fingertip instrument mechanism, an instrument replacement mechanism, an instrument rotation mechanism, an instrument opening and closing mechanism, and an instrument limiting mechanism; the body 30 adopts a sleeve structure; The fingertip instrument mechanism includes a fingertip part and a support tube 5; one end of the support tube 5 of the fingertip instrument mechanism is arranged in the hole at the front end of the body 30 sleeve; the instrument dismounting mechanism adopts a steel ball chuck structure, which includes a plurality of steel balls 68, an operating ring 16, a transmission sleeve 29 and a spring 67, and the front end surface of the transmission sleeve 29 is pro...

Abstract

The invention discloses a micro manipulator for throat operation, which comprises a body a finger tip mechanical mechanism, a remove mechanism, a rotation mechanism, a switch mechanism, and a limit mechanism. Compared with existing technique, this invention has benefit as: 1. the series-type envelope distribution can decrease finger radial size fit to narrow space; 2. the approximate crank rocker mechanism, which composes of a throat clamp, a pin, a drive steel wire and a screw, can transfer motion precisely and obtain required stretch angle.

Description

technical field [0001] The invention relates to a medical device, in particular to a component of the medical device used in laryngeal surgery. Background technique [0002] Chinese invention patent 03100038.x discloses "a micromanipulator for microsurgery", which includes a body, a fingertip instrument mechanism, an instrument replacement mechanism, an instrument rotation mechanism, an instrument opening and closing mechanism, and an instrument limit mechanism, but At present, this mechanism is only used in microsurgery, and cannot fully meet the operation requirements of laryngeal surgery. The existing foreign surgical micromechanical fingers mainly use piezoelectric drive and memory alloy drive. The opening angle of the finger is relatively small in the way of piezoelectric drive, and the force generated is relatively small. If a relatively large force is to be generated, the volume and weight will be large. The response of the micro-mech...
