Description
Technical field
This utility model relates to a kind of medical endoscope, particularly a kind of all-round visual fujinon electronic video endoscope.
Background technology
In the medical field, fujinon electronic video endoscope be usually used in observe patient body in situation, common fujinon electronic video endoscope has electrolaryngoscope, electronic gastroscope etc.Fujinon electronic video endoscope primarily of single CMOS or CCD photographic head, hollow guiding tube and control display module composition; Photographic head is located at the front end of guiding tube, can admittance line in the pipe of guiding tube, the rearward end connection control display module of guiding tube.When using fujinon electronic video endoscope, in the body that guiding tube inserts patient (as the oral cavity portion from patient inserts), during to somewhere in patient body, photographic head carries out making a video recording or taking, and medical personnel watch relevant image in real time by display module.
The visible angle of photographic head generally refers to its horizontal viewable angle and plumb visible angle, that is photographic head can be seen or photograph thing in the visual range of horizontal viewable angle and plumb visible angle, exceed this visual range just clap less than.But, due to medical single in peep the visible angle of photographic head limited, be generally 60 degree to 140 degree, so a photographic head is the all-round image cannot seeing that in patient body, visual range is larger, 140 degree are for horizontal viewable angle and plumb visible angle, its visual range to be visible angle the be border of 140 degree, and current demand is medical personnel wishes to see that complete visible angle is more than or equal to a border image of 180 degree.
Although market there is a kind of ultra wide-angle imaging head, its visible angle can reach 180 degree, and this ultra wide-angle imaging head installs a wide-angle lens on photographic head, and the distortion factor of its all-round image is higher, is unfavorable for that medical personnel judge and diagnosis and treatment pathological tissues.Namely generally can think like this: photographic head visible angle is less, image is more not yielding.
In order to solve the problems of the technologies described above, prior art rotates adjustment camera position by external strength to reach expansion visual range, i.e. the rotating endoscope of a kind of photographic head.But this endoscope's internal structure is complicated, and higher to the requirement of accessory, its mechanical component is not only accurate tiny, and processing cost is high, and fault rate is also higher.External this endoscope that once occurred breaks down and the case of can not getting out in patient body, the safety of serious threat patient.
Chinese invention patent application CN104042178A discloses a kind of flat mirror reflects formula 360 ° of wide area full-view endoscope, comprise transparent eccentric adjusting sleeve and rotating plane mirror system, plane mirror is one is the plane mirror of 45° angle with the plane camera lens of photographic head, plane mirror is fixed in micromachine rotating shaft, and micromachine is fixedly mounted in transparent eccentric adjusting sleeve inner ring.
In brief, foregoing invention application arranges a plane mirror at an angle with it, replaces photographic head of the prior art to rotate by the rotation of plane mirror.But this technical scheme has following defect:
1, endoscope rotating with photographic head is the same, and it designs complexity, and accessory measure of precision is high, and processing cost is high, at the bottom of reliability etc., element once damage its maintenance difficulty and cost higher;
2, owing to being that photographic head rotation is found a view, therefore the all-round image of gained is that multiple image mosaic forms, and need complicated successive image process, analysis and calculation, software requirement is high, and the image provided is not real-time.
3, the so-called 360 ° of wide area visual angles of this patent application, its visual range is equivalent to the all-round splicing image that visible angle equals 180 degree, because its structure limit, can not obtain the all-round image that visible angle is greater than 180 degree.
Another part Chinese invention patent application CN104127164A discloses a kind of portable intelligent medical endoscope, and its technical scheme is mainly: comprise a telescopic sleeve pipe, and the inside, front end of telescopic sleeve pipe is fixed with two CMOS camera and two LED cold light sources; Be provided with hemispherical bell glass in the leading section of telescopic sleeve pipe, CMOS camera and two LED cold light sources are enclosed in telescopic sleeve pipe; Spring-like cable is provided with in telescopic sleeve pipe; Described be positioned at telescopic sleeve pipe front end CMOS camera and LED cold light source be installed in the normal direction of spherical glass cover, and be positioned at same sphere; Described spring-like cable and CMOS camera, LED cold light source junction, all have 135 ° of angle of bends, the line of two CMOS camera installation sites is vertical with the line of two LED cold light source installation sites.
Although the structure of this patent application wants simple, but defect is two photographic head still cannot accomplish that visible angle is more than or equal to the shooting of the all-round image of 180 degree, and the design of two spring-like cables can cause the caliber of telescopic sleeve pipe to become large, be unfavorable for the insertion of endoscope or the bending of telescopic sleeve pipe, also can cause discomfort to patient.
To sum up, do not have in current prior art a kind of structure simple, safeguard convenient, reliability is high, image procossing mode is simple and easy and undistorted, and visual range is equivalent to the all-round visible electronic endoscope that visible angle is more than or equal to 180 degree.
