Description
Technical field
The present invention relates to a kind of endoscope, especially a kind of endoscope with camera handle and 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.
Summary of the invention
But the object of the present invention is to provide inflation of a kind of shunting and transfusion, improve inspection and therapeutic effect and disposable use, convenient hand-held band camera handle and the endoscope of sheath.
For realizing above purpose, the present invention has 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, and 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; Be provided with in this 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.
By the use of sheath, guarantee that endoscopic apparatus 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; The water jet of drain passage setting helps to clean the outer wall of lens jacket, prevent owing to booty attached to the last effect of observing that influences, the gas that spray the gas outlet of air guide channel further improves the cleaning effect of camera lens outer wall, guarantee the clean and transmittance of lens jacket, improved the definition of endoscope.
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.
Described outer wall is the inclined-plane that is obliquely installed, and described CCD is connected to this outer wall place and is provided with.Adopt the setting on inclined-plane, make current that the water jet of drain passage ejects after having scrubbed outer wall,, make booty can better flow out in the sleeve pipe, reach reasonable cleaning performance owing to possessing certain gradient.
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, throws away sheath again after making it break away from handle main body, has avoided cross infection.
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.
The present invention 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; 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 improve the definition of endoscope, the present invention's practicality simple to operate, cost of equipment maintenance is low.
