Description
Technical field
This utility model relates to a kind of clinical medicine apparatus, especially a kind of perforation of ear drum measuring device.
Background technology
When the treatment perforation of ear drum, patient's ear perforation of ear drum data need to measure exactly, could improve the operation precision.Using conventional endoscopy of ear can only carry out qualitative examination to the perforation of ear drum, can not accurately measure perforation size, erroneous judgement takes place sometimes and the influence treatment.
The utility model content
The purpose of this utility model provides a kind of perforation of ear drum measuring device, the especially a kind of measuring device that can measure perforation of ear drum data exactly.
The technical solution adopted in the utility model is: a kind of perforation of ear drum measuring device, form by the blade and the vernier that can on blade, slide, also comprise the spy silk that constitutes by two symmetrically arranged spy silk sheets, visit the silk sheet for two and at one end overlap to form v-shaped structure, the front end of blade is provided with bayonet socket, the back side of vernier is fixed in the described V-arrangement bottom of visiting the silk sheet, and the other end passes bayonet socket and stretches out to the place ahead of blade; Be carved with scale on blade and the vernier respectively, vernier is provided with the toggle that the control vernier slides.
Preferably, described two of visiting silk visit the silk sheet and are respectively equipped with flex point, and the flex point both sides are visited the silk sheet and designed in obtuse angle.
Preferably, described spy silk is parallel to each other in two spy silk sheets of flex point outside.
Preferably, described two the spy silk sheets of silk in the flex point outside of visiting open to both sides.
Preferably, the described spy silk head surface slyness of visiting silk.
Preferably, described vernier is provided with set screw.
Preferably, described blade front end is gradually narrow to the bayonet socket direction.
The beneficial effects of the utility model are: drive the spy silk by vernier and in bayonet socket, slide, be used, obtain measurement result with macropore scale and aperture scale, and simple in structure, easy to operate.Visit silk and be divided into macropore spy silk and aperture spy silk, be suitable for different patients; By the fixing measurement result of visiting silk of set screw, can obtain measurement result more accurately, so that improve the operation precision.

The specific embodiment
As accompanying drawing 1-5, this utility model perforation of ear drum measuring device is made up of the blade 9 and the vernier 5 that can slide on blade 9, structure between described blade 9 and the vernier 5 adopts factory's slide gauge structural principle, also comprise visit threads 2, trip bolt 10 and be arranged on toggle 6 on the vernier 5; Described spy silk 2 constitutes setting by two symmetrically arranged spy silk sheets, visits the silk sheet for two and at one end overlaps to form v-shaped structure, and the bottom 13 of V-type is provided with visits silk fastener hole 14, and trip bolt 10 will be visited the back side that silk 2 is fixed on vernier 5 by visiting silk fastener hole 14; Blade 9 front ends are provided with bayonet socket 3, this bayonet socket 3 is provided with two card bases 31, visiting the silk sheet for two places respectively in two card bases 31 of bayonet socket 3, take this bayonet socket 3 may command and visit the opening angle of silk 2, be carved with macropore scale 7 and aperture scale 8 on vernier 5 and the blade 9, by stirring the toggle 6 on the vernier 5, vernier 5 drives visits silk 2 slip in bayonet socket 3.
Visit on the silk sheet flex point 11 is set.Because patient's perforation of ear drum has size, can dispose aperture spy silk 12 (Fig. 4) and macropore and visit silk 15 (Fig. 5) two cover spy silks, aperture is visited silk 12, and to visit the silk sheets two of flex point 11 outsides parallel to each other, and macropore is visited silk 15 and visited silk sheets two of flex point outside and open to both sides.The doctor can select to use aperture to visit silk 12 or macropore spy silk 15 according to the size of the perforation of ear drum, and is used with macropore scale 7 and aperture scale 8, obtains measurement result.
The elasticity of visiting silk 2 is good, and the doctor grasps blade 9 usefulness finger and stirs toggle 6 on the vernier 5, and vernier 5 drives to be visited silk 2 and slide in bayonet socket 3, and vernier 5 is along blade 9 when mobile backward, visits threads 2 and opens; When vernier 5 moves forward along blade 9, visit 2 of silks and close up.The slide calliper rule that vernier 5 and the structure between the blade 9 are used as factory.
Preferred blade 9 narrows down gradually to the direction of bayonet socket 3, in use conveniently probes in patient's ear.Two spy silk sheets visiting silk 2 are respectively equipped with flex point 11, and flex point 11 both sides are visited the silk sheet and designed in obtuse angle, are in order to allow the doctor can see the measurement situation clearly.Visit silk 1 and have color, see clearlyer in order to the doctor.It is slick and sly to visit silk 1 surface, the elasticity of visiting silk 2 is good, thereby guarantee to visit on the inwall that silk 2 can be attached to bayonet socket 3 and when not being subjected to other external force, can accurately measure data punctured, can permanent deformation when guaranteeing to visit silk 2 and being subjected to slight external force, the auditory meatus that also can not hinder the patient.On macropore scale 7 or aperture scale 8, can directly see measurement data, to visit silk after also dog screw 4 can being tightened and 2 release from patient's auditory meatus, reuse is visited silk 1 and is dipped in color, for example medical color " methylene blue ", on graft, put on the marking then, so that improve the operation precision.
