Description

A kind of endoscope with camera handle and sheath

Technical field

This utility model relates to a kind of endoscope, the especially a kind of band camera handle of graduation mark and endoscope structure of sheath of being marked with on 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 this kind sheath can't intuitively embody size that endoscope enters human body what; therefore can not recognize effectively that in operation process endoscope enters the size of human body, might affecting to operation.

Summary of the invention

The purpose of this utility model be to provide a kind of and improve inspection and therapeutic effect and disposable use, can conveniently write down endoscope enter human body size what the band camera handle and the endoscope of sheath.

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, this casing pipe sleeve is located on the stay pipe, is provided with what the graduation mark of size that indication endoscope enters human body on described bushing outer surface.

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; Owing on bushing outer surface, be marked with graduation mark, therefore in use, to endoscope stay human body size can well be shown in some graduation marks on the sleeve pipe, help user intuitively to understand what of size that endoscope enters human body, precision with effective grasp operation improves the effect of operation.

Being the rear end near an end of handle main body on the described sleeve pipe, is front end away from an end of handle main body; This sleeve pipe rear end is provided with flange ring, and the original position that front end is connected with the described graduation mark of lens jacket is arranged at a telescopic end at described lens jacket place, and the distance between every adjacent graduation mark is 1cm.

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.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.

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

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; Owing on bushing outer surface, be marked with graduation mark, therefore in use, can well be shown in some graduation marks on the sleeve pipe, help user intuitively to understand what of gas transmission or transfusion liquid or transfer of gas capacity, precision with effective grasp operation improves the effect of operation.
