Embodiment Construction

[0023] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0024] to combine figure 1 , The manual micromanipulator for minimally invasive surgery of the present invention is mainly composed of a fingertip clamping mechanism 1, a connecting pipe 2, a pre-tightening sleeve 3, a transmission and conversion device 4, and a housing 5.

[0025] to combine figure 2 , the pretension shaft 2-2 is fixed on the outside of the pipe wall of the connecting pipe 2-1, and can move in the T-shaped groove of the pretension sleeve 3. When it moves to the bottom end, the required fingertip drive rope (lower) 1 -4. The rope length of the fingertip driving rope (upper) 1-5 is the shortest. When the connecting pipe 2-1 is rotated so that the pretension shaft 2-2 is stuck in the pretension sleeve 3 grooves, the required rope length is longer.

[0026] to combine image 3 , one side of the drive wheel cantilever shaft (top) 4-18 is fixed on ...

Abstract

The present invention provides a manual miniature mechanical hand used for minimally invasive surgery operation, which mainly consists of a fingertip clamping mechanism, a connecting pipe, a preloading jacket, a transmission and transfer device and a shell. The fingertip clamping mechanism comprises two fingertips. The connecting pipe is provided with a preloading shaft. The transmission and transfer device comprises a base plate, two driving wheel cantilever shafts and a rotating and transferring button which are arranged at the base plate. The driving wheel cantilever shaft is provided with a driving wheel and a pinion. The rotating and transferring button is equipped with a gearwheel. A rack with a guide slot is sheathed at the shaft of the gearwheel. The rack is articulated with a connecting rod which is articulated with a spanner. The spanner is provided with a spanner rotating shaft. The manual miniature mechanical hand which is used for minimally invasive surgery operation and designed by the present invention not only has free open and close degree, but also has free pitching degree, which meets the requirement of reachable space of the operation well. According to the design of human engineering, the free rotating degree of the wrist is used, so the mechanical hand of the present invention has better practicability.

Description

(1) Technical field [0001] The invention relates to a medical device for surgical operations, in particular to a manual micro-manipulator with pitch freedom. (2) Background technology [0002] Minimally invasive surgery has the characteristics of less trauma, less pain and faster recovery. It uses advanced surgical instruments and equipment to complete the operation with minimal trauma and achieve good curative effect. At present, domestic abdominal surgery mainly uses manipulators with two degrees of freedom of opening and closing and rotation. This kind of manipulator lacks the degree of freedom of pitching, and the control of the degree of freedom of rotation cannot meet the requirements of ergonomics, so it has a great impact on the operation of the operation. (3) Contents of the invention [0003] The purpose of the present invention is to provide a manual micro-surgery for minimally invasive surgery that has pitch freedom, is cheap, easy to operate, has a small sur...
