Abstract
A flexible oral endoscope belongs to an oral endoscope and comprises a viewing head and a grip, wherein, the viewing head is connected with an object lens and lighting lamps, the object lens is composed of a CCD target face and a lens, signal lines of the object lens and lighting leads on the viewing head are led out through the grip, a flexible conduit is connected between the viewing head and the grip, and the lighting lamps are distributed around the object lens to form an annular lighting lamp. The utility model adopts annular optical fiber for lighting, the lighting intensity is strong when the object lens collects images, light rays are even at a collected position, and image signals collected through the object lens are transferred to a monitor to be converted to clear images which are visible for human eyes. Because the CCD target face is preposed, the flexible conduit is used for connecting the CCD viewing head and a handle part by utilizing the characteristic of flexibility of the optical fiber for lighting and a CCD transmission line, therefore, the oral endoscope has the flexibility of omnibearing movement and achieves the omnibearing observation of the inner part of the oral cavity, better facilitating the observation and the diagnosis of dentists.
Description
Technical field this utility model relates to a kind of stomatology endoscope, particularly a kind of flexible stomatology endoscope.
Background technology is present, make a general survey of domestic and international stomatology endoscope, its stomatology endoscope front end has a viewing head, be connected with composition lens and illuminating lamp on the viewing head, composition lens is made of CCD target surface and camera lens, the CCD target surface is positioned at the rear portion of camera lens, illuminating lamp is positioned at a side of composition lens, illuminating lamp generally adopts fiber-optic illuminated or LED illumination, rigid conduit and handle have been linked in sequence behind viewing head, camera lens in the composition lens is imaged onto the picture signal that collects on 1/6 o'clock the high Definition CCD target surface, transferring optical signal to video (VIDEO) signal by the CCD target surface sends, accept by monitor, transfer the visible image of human eye on monitor, composition lens holding wire on the viewing head and lighting lead are derived through rigid conduit and handle.No matter this stomatology endoscope is with fiber-optic illuminated, or throws light on LED, because illuminating lamp is the point-like illumination, and illuminating lamp is positioned at a side of composition lens, illuminating ray dimness, relatively the composition lens illuminating ray is inhomogeneous, and is unintelligible by composition lens collection, the image that sends out; Because its conduit and handle are rigid structure, i.e. inflexibility utilizes this stomatology endoscope can not comprehensive observation disease in mouth situation, as is inconvenient to observe the back and arranges tooth; Be inconvenient to observe each position mucosa of oral cavity etc., can not reach the purpose of comprehensive inspection disease in mouth.
The summary of the invention the purpose of this utility model be to provide a kind of illuminating ray evenly, flexible stomatology endoscope that can comprehensive inspection disease in mouth.
The purpose of this utility model is achieved in that between viewing head and handle and is connected with flexible conduit; Illuminating lamp is distributed in around the composition lens, the looping illuminating lamp.
Illuminating lamp is that optical fibers is arranged in ring-type, is distributed in around the camera lens of composition lens.
Beneficial effect: owing to adopt such scheme, this utility model adopts the ring optical fiber illumination, illuminance is strong during the composition lens images acquired, and it is even to be gathered position light, by object lens the image signal transmission of gathering is converted to the visible clear picture of human eye to monitor; Because it is the CCD target surface is preposition, utilize lighting fiber and the softish characteristics of CCD transmission line, adopt flexible conduit that the CCD viewing head is linked to each other with handle part, thereby make the pliability with comprehensive change of stomatology endoscope, realized the comprehensive observation of inside, oral cavity, be more convenient for observation, the diagnosis of odontologist, reached the purpose of this utility model.This stomatology endoscope can comprehensive inspection disease in mouth, observe each position mucosa of oral cavity and change, and has solved the problem that stomatology endoscope is observed back row's tooth inconvenience, for the diagnosis and treatment of oral disease and the communication between doctors and patients provide great convenience.
Description of drawings Fig. 1 is a structure chart of the present utility model.
Specific embodiment embodiment 1: its stomatology endoscope front end has a viewing head 9, be connected with composition lens 2 and illuminating lamp 1 on the viewing head 9, composition lens 2 is made of CCD target surface and camera lens, the CCD target surface is positioned at the rear portion of camera lens, illuminating lamp 1 is distributed in around the composition lens 2, for optical fibers is arranged in ring-type, the looping illuminating lamp is connected with flexible conduit 3 between viewing head 9 and handle 4; Composition lens holding wire 6 on the viewing head 9 and lighting lead 5 are derived through flexible conduit 3 and handle 4.
Claims (2)
1, a kind of flexible stomatology endoscope, this stomatology endoscope comprises viewing head and handle, be connected with composition lens and illuminating lamp on the viewing head, composition lens is made of CCD target surface and camera lens, composition lens holding wire on the viewing head and lighting lead are derived through handle, it is characterized in that: be connected with flexible conduit between viewing head and handle; Illuminating lamp is distributed in around the composition lens, the looping illuminating lamp.
