Description

A kind of endoscope with camera handle and sheath

Technical field

This utility model relates to a kind of endoscope, the band camera handle that especially a kind of CCD camera lens is preposition and the endoscope 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, can not effectively expand operative region because conduit does not possess the qi of chong channel ascending adversely function, very easily cause accident surgery, on the other hand, the CCD of the hard tube endoscope camera lens of prior art is arranged on handle rear end, and front end has optical fiber or camera lens.The shortcoming of this method to set up is from the point of observation hypertelorism, and optical fiber or camera lens increase the light loss consumption, relative clear inadequately of image.

Summary of the invention

But the purpose of this utility model is to provide inflation of a kind of shunting and transfusion, improves inspection and therapeutic effect and disposable use, convenient band camera handle hand-held, that the CCD camera lens is preposition 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, 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; 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.

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 foul 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.

Described outer wall is the inclined-plane that is obliquely installed, 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, owing to possess certain gradient, make foul can better flow out in the sleeve pipe, reach reasonable cleaning performance.

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.

This utility model compared with prior art, have following advantage: 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 by the caused barrel distortion of optics, pincushion distortion, color disappearance, and can not use optical fiber, reduce maintenance and assembly cost.
