Abstract

The invention discloses a bendable steering endoscope which comprises a handle and a guide pipe, wherein the handle is equipped with a central through hole, the guide pipe is provided with a steering passage and a working passage, the steering passage is provided with a steering steel wire, the handle is provided with a sliding block, the inner end of the guide pipe is fixedly connected with the central through hole of the handle, the working passage positioned at the inner end of the guide pipe is connected with the pipeline in the central through hole of the handle, the outer end of the guide pipe is provided with a protective metal sleeve, the steering passage in the guide pipe is provided with a positioning sleeve pipe, an elastic pipe is arranged in the guide pipe arranged between the positioning sleeve pipe and the protective metal sleeve, the steer steel wire penetrates through the positioning sleeve pipe and the elastic pipe, one end of the steer steering wire is fixedly connected with the protective metal sleeve and the other end is fixedly connected with a sliding block. The invention has simple operation, can accurately control a steering angle, realized the steering in a total range with a 360 degree visual angle, and completely eliminates dead angle, thereby bringing guarantee to the operation safety.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a bendable steering endoscope. Background technique [0002] The current endoscope generally controls its bending and steering through scissor handles and steering wires. The operation accuracy is not high, the control of the steering angle is not accurate enough, and the viewing angle is small. Due to the technical bottleneck caused by the size of the pipe and the blind angle, Bring hidden danger to the safety of operation. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned background technology, and provide a bendable steering endoscope, which has the characteristics of simple operation and convenient control of the steering angle. [0004] The invention provides a bendable steering endoscope, which includes a handle with a central through hole and a catheter, a steering channel and a working chann...
