Clamping device and electric power system of endoscope

Abstract

The invention provides a clamping device and an electric power system of an endoscope. The electric power system of the endoscope comprises a drive rocker, a steel rope, a motor device, a transmissiondevice, a clamping device and a rotation shaft, wherein the steel rope is wound on the rotation shaft, and two ends of the steel rope are separately connected with two opposite ends of the drive rocker; both the transmission device and the clamping device are arranged on the rotation shaft, the transmission device is arranged at two ends of the clamping device, the motor device drives the transmission device to rotate, and when the clamping device is in a clamping state, the transmission device drives the clamping device to rotate. According to the electric power system of the endoscope provided by the invention, no retardance exists from pushing the drive rocker over by a finger to achieving a bend, so that the point to be observed can be quickly and accurately found; the bend is prone to achieve, the finger is not easy to fatigue, and the magnitude of the bend resistance can be sensed by the finger, so that the situation that the bend part of the endoscope is easy to damage when inuse is avoided; and the extension of the steel rope after long-term use is greatly reduced.

Description

technical field [0001] The invention relates to the field of endoscopes, in particular to a clasping device and an endoscope electric power assist system. Background technique [0002] Endoscope is a precision instrument combined with optics, precision machinery and electronic technology. It can conveniently and quickly inspect the interior of various machines, equipment and assembled objects without disassembling or destroying the assembly. Therefore, it is widely used in industry, anti-terrorism and Various fields of the national economy such as the military have a wide range of uses and important roles. [0003] As the use of endoscopes becomes more and more widespread, and their use places become more and more diverse, the operability requirements for endoscopes are getting higher and higher. For example, it is required to hold the handle of the endoscope with one hand and be able to bend Controlling, photographing, video recording and menu operation, etc., the other ha...

AI Technical Summary

Problems solved by technology

[0007] When controlling a 360° corner, the force to push the joystick is a combination of the forces required for cornering in two directions, so the thrust is large and the fingers are prone to fatigue;

[0010] However, the electric angle endoscope has its inherent disadvantages: its control method is that the finger pushes the rocker to dump, the rocker drives the motor to rotate through the circuit, and the motor drives the angle to control the wire rope to move, and finally realizes the angle

[0012] This kind of motor-assisted angled endoscope has solved the shortcomings of electric angled endoscopes, but it still has its inherent disadvantages: the steel wire rope for bending angles must first let the rotating body elastically deform, obtain motor assistance, and then bend Angle, so the tension on the wire rope is greater than that of other angle driving methods. After a long time of use, the length of the wire rope leads to a smaller guide or even no guide

[0015] 1. There is bound to be a delay from pushing the joystick with your finger to turning the corner, which makes it difficult for users to quickly and accurately find the point to be observed during manipulation;

[0016] 2. In a narrow space, when the bending part encounters resistance, the fingers operating the rocker will not feel it, and will continue to perform bending operations, which will easily cause damage to the endoscope;

[0017] 3. When withdrawing from the insertion tube, if the operator forgets to control the bend to make it straight, since the motor will not rotate by itself, it is easy to cause damage to the bend of the endoscope or the wire rope

[0019] 1. To operate the wire rope at the corner, the rotating body needs to be elastically deformed first to get the power of the motor, and then bend the corner. Therefore, the tension on the wire rope is greater than that of other corner driving methods. After a long time of use, the extension of the wire rope will cause the guide to become smaller even unguided;
