Description

Compatible three-dimensional hard tube endoscope

Technical Field

The present invention relates to a device of a medical instrument, and more particularly, to a medical three-dimensional hard tube endoscope.

Background

The medical hard tube endoscope is divided into a neuroscope, an intervertebral foramen mirror, a urethra cystoscope, a thoracoscope, a laparoscope, a hysteroscope, an arthroscope, a nasopharyngoscope and the like according to different parts reached by the endoscope. Although the endoscope in the current market can be visualized, the endoscope generally can only display the detected image in two dimensions, and cannot observe the detection information in the body more comprehensively and stereoscopically; some endoscopes have three-dimensional displays, such as three-dimensional laparoscopes, but are expensive and difficult to popularize due to the large amount of computation of the image processing part.

Therefore, how to provide a novel three-dimensional hard tube endoscope with clear images, low price and easy popularization is the research object of the utility model.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough of above-mentioned technique and providing a three-dimensional hard tube endoscope of compatible formula, propose on original two-dimentional hard tube endoscope imaging equipment's basis, utilize the optics principle, will control two tunnel images and form images in an imaging field of vision to improve operation doctor's three-dimensional consciousness greatly, reduced clinical operation's the degree of difficulty, simultaneously, the utility model discloses utilize original traditional two-dimentional hard tube endoscope imaging equipment, cost greatly reduced is suitable for popularizing.

In order to achieve the above object, the utility model provides a technical scheme that prior art problem adopted is: a compatible three-dimensional hard tube endoscope.

The above technical solution is further described as follows:

the utility model relates to a three-dimensional hard tube endoscope of compatible formula, including camera lens, left objective, right objective, outer tube, optical fiber bundle, left inner tube, right inner tube, left light path device, right light path device, eyepiece seat and shell.

The utility model provides a three-dimensional hard tube endoscope of compatible formula, it utilizes the optics principle, will control two way image formation in an imaging field of vision, on original traditional two-dimentional hard tube endoscope imaging device basis, can obtain good vision three-dimensional image, has improved inspection doctor's three-dimensional consciousness greatly, has reduced clinical application to operating doctor's technical requirement, has improved the utilization ratio of social medical resources, is of value to the solution of "seeing a doctor hard" problem.
