Rotatable electronic hard tube endoscope

Abstract

The invention discloses a rotatable electronic hard tube endoscope, relates to the technical field of medical instruments, and aims to change an observation view angle in a labor-saving manner, so that the view field range can be expanded conveniently. Comprising an operating handle, an endoscope tube is axially installed at the first end of the operating handle, a camera is installed at the front end of the endoscope tube, and a first channel is formed between the first end and the second end of the operating handle; an outer lens tube is mounted in the outer lens tube seat; a first channel is formed between the first end and the second end of the rotating wheel, a second channel is formed between the first end and the second end of the rotating wheel, the second end of the outer endoscope tube seat is fixedly connected into the second channel of the rotating wheel, the first end of the operating handle penetrates through the rotating wheel from the second end of the second channel, and the inner endoscope tube is located in the outer endoscope tube; and the operating handle is rotatably arranged relative to the rotating wheel. The invention is suitable for clinical medical examination and operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a rotatable electronic rigid tube endoscope. Background technique [0002] The emergence of the endoscope has brought great help to the detection and operation of clinical patients with internal lesions. In order to expand the field of view of observation, in some implementations of endoscopes, the front end of the endoscope tube is generally designed with a flexible flexible hose. When performing clinical testing, the rear end handle can control the The front-end hose section is bent in different directions to change different viewing angles, thereby expanding the viewing field. [0003] However, the inventors of the present application found in the process of realizing the invention of the present invention that: during the use of the above-mentioned types of endoscopes, the knob on the handle is generally turned, and the steel wire and other pulling members connec...

[0003] However, the inventors of the present application found in the process of realizing the invention of the present invention that: during the use of the above-mentioned types of endoscopes, the knob on the handle is generally turned, and the steel wire and other pulling members connected to the front end are used to pull the endoscope. The front-end hose section bends it to change the direction of the viewing angle. This method of expanding the field of view is laborious to operate.
