Description
Technical field
The utility model is related to the field of medical instrument technology, more particularly to one kind is for vaginal disease diagnosis and treatment and with benefit
The video vaginal speculum of electro-optical device.
Background technology
The effect of video vaginal speculum is to stretch into vagina by upper duckbilled piece, the lower duckbilled piece being hingedly connected together, so
Vagina is opened afterwards, doctor observes the situation of vagina intra focal by the methods of camera shooting.As Patent Office of the People's Republic of China exists
June in 2016, the notification number of Granted publication on the 1st was the utility model patent of CN205268137U, and which disclose a kind of vaginas
Sight glass, includes the upper and lower duckbilled piece and camera, display, control system of articulated connection, and the rear end of lower duckbilled piece is set
There are hollow handle, the lower duckbilled piece madial wall to be equipped with protrusion, protrusion extends along lower duckbilled piece to handle madial wall, protrusion
Interior to be equipped with cavity, the cavity one end open other end is closed, and the blind end of cavity is located in lower duckbilled piece, the open end position of cavity
In in handle, the camera is located in the blind end of cavity, and the control system is connected with camera, display respectively.
Vaginal speculum described in the patent does not have a light compensating apparatus, and the light source that only carries by camera illuminates, due to by camera from
The limitation of body product, the light-source brightness for causing camera included is insufficient, and the lesion image of shooting seems not clear enough because of dim light
It is clear, it is unfavorable for accurate judgement of the doctor to the state of an illness.
Invention content
To overcome drawbacks described above, the utility model technical issues that need to address to be to provide a kind of regarding with light compensating apparatus
Frequency vaginal speculum, so as to can be obtained when doctor's diagnosis and treatment it is bright, clearly, the video image of high quality, be conducive to doctor couple
The state of an illness of patient makes accurate judgement.
The technical solution adopted in the utility model is：A kind of video vaginal speculum with light compensating apparatus, including sight glass head,
Sight glass head is equipped with the upper duckbilled piece of articulated connection, lower duckbilled piece, and the lower duckbilled piece is towards setting on the one side of upper duckbilled piece
There is hollow cavity, camera is equipped in cavity, supplementary lighting sources is additionally provided in the cavity, every aperture, camera is located at every light
In circle, supplementary lighting sources are located on the outside of aperture, and supplementary lighting sources are arranged in the shooting direction of camera relative to camera rearward,
Cavity is equipped with the first transparent isolation board in the front side of camera shooting direction, and cavity is set on front side of supplementary lighting sources direction of illumination
There is the second transparent isolation board, has every photo structure between the first isolation board and the second isolation board.It is well known that in camera
Side configuration supplementary lighting sources will be such that camera shoots if supplementary lighting sources have the taking lens that some light enters camera
Image there are the light interference phenomenas such as halation, hot spot, keep image no longer clear；Due to going deep into inside vagina carrying out the vagina of diagnosis and treatment
Sight glass is inevitably polluted by patient's body fluid, in order to prevent patient's cross-infection, and price is more valuable to be taken the photograph
As head and supplementary lighting sources needs be effectively isolated, so as to reuse, reduce the medical treatment cost of patient；Based on upper
The situation to be stated to may determine that, the light of supplementary lighting sources enters there are three types of the approach of camera taking lens, and 1, supplementary lighting sources
Light be directly entered in camera taking lens, 2, the light of supplementary lighting sources occur when passing through transparent isolation board scattering,
Refraction effect and enter in camera taking lens, 3, the light of supplementary lighting sources enter after isolation board inside isolation board conduct to
In the taking lens of camera.For the first approach, the utility model is lighttight in the peripheral side of camera socket one
Every aperture, camera and supplementary lighting sources are kept apart, the light of supplementary lighting sources is made not to be directly entered camera taking lens；Needle
To second of approach, supplementary lighting sources are arranged in camera shooting direction opposite rearward position by the utility model, make light filling
Scattering occurs when passing through isolation board for the light of light source, refraction can not enter camera taking lens；For the third approach,
The utility model configures isolation board split settings, the configuration of the first isolation board in light filling in the front side of camera, the second isolation board
The front side of light source, and between the first isolation board and the second isolation board setting every photo structure, cut-out light two isolation boards it
Between conduction.Three kinds of approach that the light of supplementary lighting sources enters camera taking lens are all cut off so that camera can be with
Clearly judgement of the image for doctor's diagnosis and treatment and curative effect of patient's lesion is shot under a bright ambient environment.
Preferably, second isolation board is equipped with through-hole at the position of camera, first isolation board is located at logical
In hole.
Preferably, described every on the madial wall that photo structure is located at through-hole.
Preferably, described every on the peripheral surface that photo structure is located at the first isolation board.
Preferably, it is described every photo structure be the diffusion layer handled by frosted.
Preferably, it is described every photo structure be the light-absorption layer that can absorb all light.
Preferably, it is described every photo structure be prevent light transmission every photosphere.
The beneficial effects of the utility model：Since three kinds of approach that the light of supplementary lighting sources enters camera taking lens are complete
Portion be cut off so that camera can shoot under a bright ambient environment patient's lesion clearly image for doctor's diagnosis and treatment and treatment
The judgement of effect is conducive to the confirmation of the state of an illness and the accurate evaluation of curative effect in this way.
