Abstract
The utility model relates to an ear endoscope, which is composed of a lens body (1), a cold light source (2), and a protecting device (3). The protecting device is installed on the lens body and can move along an axis of the lens body. The position of the protecting device determines the depth of the ear endoscope penetrating into external auditory meatus, which has the function that ear drum is protected from harm during diagnosis. The utility model can be used in ENT departments and medical colleges.
Description
This utility model relates to a kind of optical fiber ear endoscope with protection tympanum device.
Present ear endoscope is made up of optical imaging system and optical fiber illuminating system usually, and they are installed in the same mirror body, and the doctor can spy on the in ear situation by the eyepiece place.As Japanese raised path between farm fields field EN-SLA, China Shenyang EJ-1; Guangzhou GE91-1 or German WOLF otoscope etc.; they compare tool observation ear with the otoscope that did not originally have optical system clear; diagnose advantages such as reliable; but because otoscope gos deep into external ear; in the situation of unprotect device, when operating otoscope, the doctor can damage tympanum accidentally, especially to unskilled doctor or the student of hospital practice.
This utility model attempts to provide that a kind of imaging is clear, diagnosis is reliable, with the otoscope of adjustable work apart from protector, when the doctor operates this otoscope diagnosis, can avoid damaging accidentally tympanum.
The otoscope of this utility model narration mainly is made of mirror body (1), cold light source (2) and protector (3).The imaging of imaging system in order to ear arranged in the otoscope mirror body, and the light that cold light source sends is by the look-out station of the intravital optical fiber illumination of mirror ear, so that diagnosis.Settle protector on the mirror body, it can move along the mirror body and make the mirror body go deep into the work of ear apart from variable, to adapt to the needs of different human body.Protector is called inner cone near being a cone by an end of diagnosis and treatment ear, and it can join with the external acoustic pore of different-diameter, and the other end is called the back cover, and fixed screw is arranged on it, is fixed on the mirror body in order to the protector that will adjust after the work distance.Protector can be divided into not to be with micro-adjusting mechanism and to be with two kinds of micro-adjusting mechanisms; in a single day the former has adjusted work and just can not finely tune apart from the back again; and the latter is because the band micro-adjusting mechanism; thereby work apart from coarse adjustment intact after; but the nationality micro-adjusting mechanism makes front portion and mirror body that one relative motion be arranged in the observation process, to reach the effect of fine setting.
This otoscope except have imaging clear, throw light on, diagnose the reliable advantage, also can avoid the mirror body to touch ear drum membrane and make film impaired, thereby reach the purpose of protection tympanum.
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is embodiment of the present utility model.
Fig. 2 is the vertical section structural map of first embodiment of protector.
Fig. 3 is the vertical section structural map of second embodiment of protector.
Fig. 4 is the vertical section structural map of the 3rd embodiment of protector.
Ear endoscope shown in Fig. 1 embodiment is characterized in that a protector (3) is arranged on the mirror body, and it can utilize it can regulate the work distance that the mirror body gos deep into external auditory meatus along the mirror axon to moving, in order to avoid maloperation damage ear drum membrane.The mirror body has imaging system in (1), and it is made up of object lens, transfer system and eyepiece, in order to observed ear position is become sharp image; The intravital light guide bundles of mirror links to each other with cold light source (2), and the light that cold light source sends is through the observed position of light guide bundles back lighting.
Fig. 2 is a kind of structural representation of protector; wherein (4) are the conical forward portion of joining with the external auditory meatus hole; (6) be the back cover of band fixing screw (5); the two links to each other inner cone (4) and back cover (6) and can move axially along mirror body (1) while; after the decision of work distance; back cover (6) is fixed on the mirror body with fixed screw (5), and the doctor can operate.The inner cone of this class protector can be used rubber, plastics or metal manufacturing, back available plastics of cover or metal manufacturing.Their overall structures are simple, but finely tune cumbersome.
Fig. 3 is the protector structural representation of another kind of band fine setting.(12) are the inner cone that joins with the external auditory meatus hole among the figure; it is made by rubber or plastics; inlay a threaded plastic sheath or metallic sheath (13) on it; (17) for being with the back cover of regulating ring (14); fixed screw (16) is arranged on it; regulating ring (14) is linked to each other by screw (15) with back cover (17); screw thread between cover (13) and the regulating ring (14) is a loose fit; when the doctor move protector determine work apart from after; with fixed screw (16) back cover (17) is fixed on the mirror body (1); rotary fine adjustment ring this moment (14) can make the relative mirror body (1) of inner cone (12) move axially, thereby reaches the purpose of fine setting.
Fig. 4 is a kind of protector structural representation of differential differential tuning; (22) are the inner cone that joins with the external auditory meatus hole among the figure; it is made by rubber or plastics, inlays a threaded plastic sheath or metallic sheath (23) in it, and (24) are regulating ring; its two end has screw thread; pitch difference but rotation direction is identical, (25) are the back cover, on screw thread is arranged; and fixed screw (26) is arranged, regulating ring (24) and back cover (25) available metal or plastics are made.Regulating ring (24) is threaded to loose fit with (23), back cover (25); the whole protecting device is enclosed within mirror body (1) and goes up and can move axially along the mirror body; when the doctor move protector determine work apart from after; with fixed screw (26) back cover (25) is fixed on the mirror body (1); rotary fine adjustment ring this moment (24) can make inner cone (22) that mirror body (1) is moved axially, thereby reaches the purpose of accurate fine setting.If the screw thread of cover (23) in the protector and back cover (25) is made left and right revolving, then fine setting is comparatively quick.
This utility model is appropriate to department of otorhinolaryngology, and the doctor is used to diagnose the patient ear state of an illness and is used for medic's otology practice, and it is safe and reliable, imaging is clear, can improve the diagnosis and treatment rate and is convenient to impart knowledge to students thereby has bigger society and economic resultant effect.
