Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of to medical endoscope.
Background technology
Along with modernized science and technology development, medical hard-tube endoscope has been widely used in medical field, and it is that the mankind spy on one of important tool of intracorporeal organ.At present the rear end pictorial display and the obtain manner of the medical hard-tube endoscope that uses clinically mainly contain three kinds: first kind, as shown in Figure 1, be in the back end design of endoscope eyepiece 37, obtain image by eyepiece 37; Second kind as shown in Figure 2, is to have the hard tube endoscope of eyepiece 37 to be incorporated on monitor or the display for 39 groups by coupling camera lens and photoelectric conversion sensor design to obtain image; The third as shown in Figure 3, is that hard tube endoscope is not with eyepiece directly to connect with photoelectric conversion sensor 39 and obtain image on monitor or display by coupling camera lens 40.
At present, the light input end Interface design of these three kinds of illumination for endoscope optical fiber all is along the radial arrangement of endoscope, the optical axis of the optical fiber that has is perpendicular to endoscope's optical axis, have optical axis and endoscope's optical axis of optical fiber angled, all there is following shortcoming in these structures along the radial arrangement of endoscope:
1, feel is heavy during endoscopic procedure: because optical fiber is along the radial arrangement of endoscope, when external optical fiber with after endoscope connects, make endoscope deviation of gravity center the optical axis of endoscope, when endoscopic procedure, produced an additional moment, the doctor must exert oneself this moment of balance when operation, make feel heavy, arm is aching and tired.That is just more difficult to feel operation inconvenience, particularly some endoscope to need rotating certain angle when operation or inspection when endoscope enters the human intracavity road.
2, endoscope's handgrip part volume increases: because the input of endoscope illumination optical fiber is to arrange along the diametric(al) of endoscope in endoscope, the radial dimension of endoscope is strengthened.Taken certain operation technique space, brought inconvenience to its use.
3, be unfavorable for the aseptic protection of endoscope: because can not soaking disinfection and high-temperature sterilization with the endoscope of eyepiece, therefore to install aseptic protective jacket additional at handgrip part usually.Because the input of endoscope illumination optical fiber is to arrange along the diametric(al) of endoscope in endoscope, formed T font structure at the handgrip part of endoscope, caused difficulty for the design and installation of the aseptic protective jacket of endoscope's handgrip part.
4, the combination and the disengaging time of the light beam 36 of endoscope and video line and external radial arrangement have been increased: because video line and external light beam and endoscope are bonded at two positions, combination with separate and must operate at two positions, more than once operation has prolonged combination and disengaging time.
5, on endoscope and external video line, beam combination line two plugs, socket are arranged, one is video line plug, socket, and another is external light beam plug 38, socket, has increased material cost and assembly cost.
The utility model content
This utility model purpose provides a kind of endoscope of axially provided with lighting fiber, and prior art endoscope feel is heavy to overcome, volume is big, be unfavorable for aseptic protection, endoscope and video line and the combination of external light beam and the technical problem that disengaging time is long and cost is high of endoscope.
The technical solution of the utility model is:
A kind of endoscope of axially provided with lighting fiber, its special character is:
Comprise the mirror body, be fixed on the mirror pipe of mirror body front end, built-in light beam and zygonema and be arranged on the interior coherent fiber bundle of mirror pipe; Described mirror body comprises lens barrel, camera lens, CCD photoelectric sensor, socket, and described coherent fiber bundle stretches into the front end of lens barrel in the mirror pipe, and described camera lens and CCD photoelectric sensor are arranged on the lens barrel bosom, and described socket is arranged on the rear end of lens barrel; Described socket comprises built-in light beam socket and the female nook closing member of video line; Described coherent fiber bundle, camera lens, CCD photoelectric sensor constitute optical imaging system, and the outfan of described CCD photoelectric sensor links to each other with the female nook closing member of video line; One end of described built-in light beam links to each other with built-in light beam socket, and its other end stretches in the mirror pipe from the front end of lens barrel, and its middle part is axially disposed within the outside of CCD photoelectric sensor and camera lens but departs from the axis of endoscope; Described and zygonema comprises external plug, video line, light beam, video line plug, light beam plug, and described external plug comprises public nook closing member of video line and light cone; One end of described video line links to each other with the public nook closing member of video line, and its other end links to each other with the video line plug; One end of described light beam and light cone coupling, its other end links to each other with the light beam plug; The public nook closing member of described video line is pegged graft with the female nook closing member of video line and is cooperated, described light cone insert built-in light beam socket interior and with built-in light beam coupling.
Parallelly in the above-mentioned mirror pipe be provided with lens barrel and light beam sleeve pipe, the front end of coherent fiber bundle and self-focusing object lens are located in the lens barrel, and the self-focusing object lens are arranged at coherent fiber bundle the place ahead, and built-in light beam is arranged in the light beam sleeve pipe.
Be provided with lens barrel and light beam sleeve pipe in the above-mentioned mirror pipe, and lens barrel is arranged in the light beam sleeve pipe; The front end of self-focusing object lens and coherent fiber bundle is located in the lens barrel, and focusing objective len is arranged at coherent fiber bundle the place ahead; Described built-in light beam is arranged between light beam sleeve pipe and the lens barrel.
Above-mentioned camera lens can be regulated vertically; But described lens barrel is provided with the camera adjusting screw of fixed lens position.
Above-mentioned lens barrel is provided with the adjustment screw of scalable coherent fiber bundle center with respect to CCD photoelectric sensor center.
Above-mentioned locking cap is provided with check lock lever, is used for the spacing of locking cap and increases locking torque;
Above-mentioned and zygonema comprises junction box, and the front end of junction box is sent into external plug with video line and light beam after parallel, and the rear end of junction box with video line and light beam separately.
Above-mentioned lens barrel is provided with locking cap, is used for the mirror sheath is fixed on lens barrel.
Technique effect of the present utility model is:
1, endoscopic procedure is light.Because illumination for endoscope optical fiber is along the axial design of endoscope, the additional moment that does not have external optical fiber to bring, endoscopic procedure is light in the operation, rotates flexibly.
2, reduce the endoscope shared space of handgrip part.Because illumination for endoscope optical fiber is along the axial design of endoscope, thereby has reduced the shared space of external optical fiber.
3, help the aseptic protection at endoscope handle position.Because illumination for endoscope optical fiber is along the axial design of endoscope, the handle part of endoscope is a cylindrical structural but not T font structure is convenient to the aseptic protective jacket of suit.
4, shortened the plug time of endoscope's video line and biography light beam.Because the video line and the light beam of endoscope are designed to two-in-one plugs and sockets, only need combination that plug once just can finish external video line, light beam and endoscope and separate.
5, reduced production cost.Because the video line of endoscope and plug, the jack design of light beam are two-in-one structure, have reduced material consumption and reduced processing and assembly fee usefulness.
