Rotating and bending control mechanism used for endoscope and convenient for finding lesion target

Abstract

The invention discloses a rotating and bending control mechanism used for an endoscope and convenient for finding a lesion target, and belongs to the technical field of endoscopes. The rotating and bending control mechanism comprises an endoscope lens, a steering adjusting mechanism, a circuit mechanism and a control mechanism; the endoscope lens is fixedly connected to one end of the steering adjusting mechanism capable of adjusting the random rotating position of the endoscope lens; and the other end of the steering adjusting mechanism is fixedly connected with the circuit mechanism with the energy output function. According to the invention, the steering adjusting mechanism is arranged; after water flow is injected into a channel, the water flow enters a containing cavity, so that the water flow can generate an extrusion effect on a first piston block; under the action of a ball seat and a rotating ball, a blocking piece can rotate, so that the angle of the endoscope lens can be effectively adjusted, and the shooting range can be effectively enlarged; and the endoscope lens does not need to be taken out and put into the human body after being subjected to angle adjustment again, so that the operation is simple, and the efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of endoscopes, and in particular relates to a rotation and bending control mechanism for endoscopes which is convenient for finding lesion targets. Background technique [0002] Endoscope is an important medical device in medical equipment. It is mainly used to detect the lesions inside the human body. The existing endoscope cannot adjust the angle when it is inserted into the patient's body, resulting in a limited viewing angle of the endoscope. , in order to adjust the angle of the endoscope, the doctor will take out the endoscope to adjust the angle and put it back into the patient's body for observation, which will bring trouble to the doctor's operation, and the observation efficiency will be greatly reduced. In the technology, a steel wire is used to control the endoscopic lens to adjust it. The flexibility of the steel wire is relatively poor, and it is not convenient to bend and is also not conducive...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is: in order to solve the problem that the existing endoscope cannot adjust the angle when it is inserted into the patient's body, resulting in a limited viewing angle of the endoscope. In order to adjust the angle of the endoscope, the doctor will take out the endoscope and adjust it. Putting it back into the patient’s body for observation will cause trouble to the doctor’s operation, and the observation efficiency will be greatly reduced. In order to facilitate switching angles, in the prior art, a steel wire is used to control the endoscopic lens to adjust it. The flexibility of the steel wire Poor, it is not convenient to bend and it is also not conducive to the adjustment of the lens, and a rotating and bending control mechanism for endoscopes that is convenient for finding lesion targets is proposed
