Electronic sleeve wearing hard tube rectum endoscope

Abstract

The invention relates to an electronic sleeve wearing hard tube rectum endoscope which comprises a gun-shaped shell with a gun barrel-shaped instrument pipeline and a handle. A water inlet pipe, an air inlet pipe, an air outlet pipe and a water outlet pipe are arranged in the handle, the handle is provided with a water and air supply valve and a water-air connector, the water and air supply valve is provided with a water-air button, the water inlet pipe is connected with the water outlet pipe through the water and air supply valve, the air inlet pipe is connected with the air outlet pipe through the water and air supply valve, a water-air connecting pipeline is arranged on one side of the gun barrel-shaped instrument pipeline, the water outlet pipe and the air outlet pipe penetrate the water-air connector and are communicated with the water-air connecting pipeline, an insert tube with a CCD (charge coupled device) objective lens is arranged in the gun barrel-shaped instrument pipeline, and a sheath tube sleeves the outside of the gun barrel-shaped instrument pipeline. The electronic sleeve wearing hard tube rectum endoscope has the advantages that a field angle ranges from 130 degrees to 140 degrees, observing range is widened, dirt can be flushed when water and air are supplied, the endoscope is convenient to use, a disposable sheath is used and removed after diagnosis, repeated cleaning and disinfection of the endoscope are omitted, the hidden danger of cross infection is avoided, and diagnosis efficiency is improved.

Description

technical field [0001] The invention relates to a rectal endoscope, in particular to an electronic sheathed rigid tube rectal endoscope. Background technique [0002] The traditional hard tube rectal endoscope adopts the principle of optical imaging, and its observation range is very limited, the field of view is 80° to 100°, and the outer diameter of the insertion tube is relatively large, generally 20mm. Infection hazard. In addition, during the use of traditional hard-tube rectal endoscopes, if dirt sticks to the mirror surface, it will seriously affect the image observation. It must be cleaned before continuing to observe, which is very inconvenient and will bring pain to patients. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide an electronic sheathed rigid tube rectal endoscope to solve the deficiencies in the prior art. [0004] In order to achieve the above object, the purpose of the present invention is achie...

Problems solved by technology

[0002] The traditional hard tube rectal endoscope adopts the principle of optical imaging, and its observation range is very limited, the field of view is 80° to 100°, and the outer diameter of the insertion tube is relatively large, generally 20mm. The biggest disadvantage is that the disinfection is not complete and there are crossover Hidden danger of infection

In addition, during the use of the traditional hard tube rectal endoscope, if the mirror surface is stuck to dirt, it will seriously affect the image observation. It must be cleaned before continuing to observe, which is very inconvenient and will bring pain to the patient.
