Abstract

The utility model discloses an endoscope with a camera handle and a sheath, comprising a handle body and a support tube. One end of the support tube is connected with the handle body; the support tube is provided with a sheath which comprises a sleeve sheathed on the support tube; one end of the sleeve close to the handle body is rear end and one end far away from the handle body is front end; the rear end of the sleeve is provided with a flange ring and the front end is connected with a lens sleeve, wherein the external wall of the lens sleeve is an inclined plane. As the external wall of the lens sleeve has a certain gradient, dirt can flow out of the sleeve better to achieve better cleaning effect; besides, the inclined plane ensures that the endoscope can enter the intestinal canal more easily than the straight-wall type lens sleeve.

Description

A kind of endoscope with camera handle and sheath

Technical field

This utility model relates to a kind of endoscope, and especially a kind of outer wall of lens jacket is the band camera handle on the inclined-plane that is obliquely installed and the endoscope structure of sheath.

Background technology

After the therapeutic medical endoscope of prior art requires the doctor to stretch into conduit in the patient body, import camera head or, the doctor is not felt quite oneself by importing optical fiber again, simultaneously patient is felt awkward by microscopic examination; And before directly inserting endoscopic catheters in the body and after the operation end, all need disinfection, can't accomplish sufferer is carried out continuous detecting, efficient operation, and frequent sterilization can not thoroughly solve pathogenic bacteria residual on the conduit; On the other hand, because the camera lens outer wall of endoscopic catheters can touch the intravital liquid or solid kenosis of people in operation process, made dirty easily and had influence on and observed and therapeutic effect, when needs are cleared up, the doctor is interrupted operation and again conduit is taken out and clean and wipe camera lens, proceed operation again, seem extremely inconvenient like this, and make the numerous and diverse accident surgery that also occurs easily of operation process, and because conduit does not possess the qi of chong channel ascending adversely function, can not effectively expand operative region, very easily cause accident surgery; The endoscope that has has the sheath armour tubing, but the sheath front end does not have wall, directly is the camera lens outer wall, generally is straight wall type.The camera lens outer wall of straight wall type is made dirty easily and is had influence on observation and therapeutic effect, can not clean in enteric cavity, and interruption is performed the operation and again conduit taken out and clean and wipe the progress that camera lens can influence operation.

Summary of the invention

The purpose of this utility model is to provide a kind of inspection and therapeutic effect and disposable use, band camera handle convenient for cleaning and endoscope of sheath of improving.

For realizing above purpose, this utility model has been taked following technical scheme: a kind of endoscope with camera handle and sheath, include the stay pipe that a handle main body and an end are connected with this handle main body, described stay pipe is provided with sheath, described sheath includes sleeve pipe, and this casing pipe sleeve is located on the stay pipe; Being the rear end near an end of handle main body on the sleeve pipe, is front end away from an end of handle main body; This sleeve pipe rear end is provided with flange ring, and front end is connected with lens jacket, and the outer wall of described lens jacket is the inclined-plane that is obliquely installed.

By the use of sheath, guarantee that endoscope is not needing under the disinfectant situation sufferer to be carried out continuous detecting, efficient operation; And the disposable use of sheath uses endoscope repeatedly to compare with prior art, has reduced the chance of infection and cross infection; Because the outer wall of lens jacket possesses certain gradient, the direct flush clean outer wall of the air water that is sprayed center produces vortical flow, current, covers whole camera lens outer wall, makes foul can better flow out in the sleeve pipe, reaches reasonable cleaning performance.

The front end of described stay pipe is provided with CCD, and this CCD is electrically connected with described handle main body by the electric lead in the stay pipe, and described CCD is connected to this outer wall place and is provided with.CCD is arranged at front end, make doctor and patient can keep a comfortable distance to observe while checking, carry out work easily, reduce the blindness of observing and reduce working strength, improved image definition simultaneously, strengthened color restoration capability, expanded visible angle, avoided problem, and can not use optical fiber, reduced maintenance and assembly cost by the caused barrel distortion of optics, pincushion distortion, color disappearance.

Described flange ring is provided with easy switch out spare, this easy switch out spare one end is fixedlyed connected with flange ring, its middle-end snaps fit onto in the draw-in groove that is arranged on the handle main body, the other end stretches out the draw-in groove setting. and this easy switch out spare one end exceeds the draw-in groove setting, and user is convenient with its switch out, easily after the fracture of switch out spare, the just easy and handle main body disengaging of sheath, at this moment can as early as possible sheath be taken out and throw away, avoid cross infection, improve operation promptness and continuity.

Be provided with in the described sleeve pipe and connect telescopic service aisle, drain passage, air guide channel, the water jet of this drain passage front end, the gas outlet of air guide channel front end are over against the outer wall setting of lens jacket.And employing drain passage, air guide channel front end water jet and gas outlet are provided with version over against the outer wall of lens jacket and make when sheath when in use the lens jacket outer wall is made dirty the influence observation, can clean outer wall by the water that water jet ejects, guaranteed the clean of lens jacket, made things convenient for and checked and treatment, use this kind structure, need not sheath is taken out wiping lens jacket again, health when having guaranteed operation has also improved work efficiency, and the gas outlet can not only be inflated to enlarge range of observation to operative region when operation, and the gas that ejects also can further improve the definition of lens jacket outer wall, thereby improves the definition of endoscope.

Described lens jacket rear end inwall is provided with cannelure, and described sleeve pipe front end sleeve is located in the cannelure and by fluid sealant and this lens jacket and is connected as one.The sleeve pipe front end is connected with lens jacket with fluid sealant by cannelure, possesses better sealing effectiveness, has prevented the intrusion of pathogenic bacteria.

Described service aisle, drain passage, air guide channel are arranged in the described sleeve pipe inner tubal wall.These passages are accommodated in the inner tubal wall, need not additionally to be provided with again passage, make that the passage in the sleeve pipe is more succinct.

Described flange ring is provided with service aisle joint, drain channel connector, the air guide channel joint that is communicated with service aisle, drain passage, air guide channel, described handle main body is provided with through hole and infusion port and the blowing mouth that wears for the service aisle joint, this infusion port is communicated with the drain channel connector, and this blowing mouth is communicated with the air guide channel joint.

This utility model compared with prior art has following advantage: use disposable shield sleeve, saved the endoscopic apparatus disinfecting time, reduced the chance of infection and cross infection; This utility model practicality simple to operate, cost of equipment maintenance is low; The outer wall of lens jacket possesses certain gradient, make current that the water jet of drain passage ejects after having scrubbed outer wall, foul can better flow out in the sleeve pipe, reach reasonable cleaning performance, need not to interrupt operation and again camera lens, the continuity that helps performing the operation are cleaned and wipes in the conduit taking-up.
