Abstract

The utility model relates to a stepping motor corner control handler for endoscope, and is characterized in that: one end of a main axis is provided with a shaft gear 1 and a shaft gear 2, two sides of the main axis are respectively provided with an upper and lower corner motor and a left and right corner motor. The main axis of the utility model is provided with two corner motors when used, the corner motor is controlled to clockwise and anticlockwise rotate by a control key, and is driven to draw a corner steel wire to move reciprocatingly by the gear, and the control key controls a control corner part to bend according to the required direction, therefore operators can control the bent angle by the key without turning a hand wheel by force, thereby achieving the requirement of easy operation, even if the utility model is operated a long time, users can not easily create fatigue, simultaneously the hand wheel is abolished, to make the size of the axial direction be decreased and the volume of the operation handler is reduced, thereby the whole endoscope is more flexible when used.

Description

A kind of motor bent angle joystick that is used for endoscope

Technical field:

This utility model relates to technical field of medical, specifically a kind of motor bent angle joystick that is used for endoscope.

Background technology:

Endoscope continues to use the bent angle direction that traditional handwheel is controlled first end always for a long time, even endoscope is constantly improved, what also just change in shape is more small and exquisite suitable, rotation torque becomes lighter in operation, but all fundamentally do not improve the HWO mode of back and forth rotating, because needing to continue to pull handwheel in practice controls the bent angle direction, the time is once often being easy to make the doctor to produce fatigue.

The purpose of this utility model is to provide a kind of motor bent angle joystick of improved endoscope, and it can overcome some shortcomings of the prior art.

To achieve these goals, the technical solution of the utility model is: a kind of motor bent angle joystick that is used for endoscope, it mainly comprises shell and is located at the interior main shaft of shell, it is characterized in that: an end of main shaft is provided with shaft gear 1 and shaft gear 2, and the both sides of main shaft are respectively equipped with bent angle motor and left and right sides bent angle motor up and down.

Main shaft of the present utility model is provided with two bent angle motors during use, control the up time and the inverse time rotation of bent angle motor by controlling key, move back and forth through gear drive rear haulage bent angle steel wire, and control bent angle portion direction bent angle on demand, so the operator can control angle of bend by button, just do not need firmly to pull again handwheel thus, reached the requirement of light and handy operation, even long-time operation, also not too be easy to generate fatigue, simultaneously because the cancellation of handwheel makes axial dimension reduce, the volume of operating grip also can diminish, and makes whole endoscope in use feel more flexible.

The specific embodiment:

The utility model will be further described below in conjunction with drawings and Examples.

This utility model mainly comprises shell 14 and is located at the interior main shaft 16 of shell that it is characterized in that: an end of main shaft is provided with shaft gear 1 and shaft gear 2, bent angle motor 3 and left and right sides bent angle motor 4 about the both sides of main shaft are respectively equipped with;

Shaft gear

1,2 is meshed with gear 5,6 respectively, and

gear

1,2,5,6 is straight-tooth, respectively is provided with central shaft 7,8 on the

bent angle motor

3,4, and central shaft 7,8 is fixedlyed connected with gear 5,6 respectively, and central shaft 7,8 is fixed on the center of gear 5,6; The other end of main shaft is provided with boot pulley 9 and left and right sides drum 10, and drum is provided with traction steel wire 11, and shell 14 is provided with controls key 15, and suitable, the de-rotation of bent angle motor are controlled; Main shaft is provided with left and right sides rotating shaft 12 outward, and the lower semisection of left and right sides rotating shaft is provided with lower rotary shaft 13.

In force, up and down bent angle motor 3 and left and right sides bent angle motor 4 control respectively first end steel wire up and down and side-to-side movement, up time by motor and inverse time rotate and drive corresponding gear and rotate, then driving main shaft by the coupling mainshaft gear again rotates, make the traction steel wire of spindle nose move back and forth, thereby adjust to actual required angle of bend, at this moment only need unclamp and control key, motor will shut down, automatically keep lock-out state, traction steel wire will the auto lock angle of bend, motor splits the both sides at main shaft, and be one positive one anti-to be fixed on same horizontal level, motor power drives rotating shaft is connected one with rotating shaft drum by meshed gears, and drum is connected with traction steel wire again, the rotation of drum is converted into moving of traction steel wire like this, and traction bent angle portion finishes bent angle and controls, and operated key is arranged on the plane of main case outside, by driving the control motor operations.
