Description

Peep the image finder in the radio-type

Technical field

The utility model relates to a kind of for medical treatment use in peep the image finder, particularly a kind ofly do not have insertions syndeton such as conduction optical fiber and in the radio-type that radio frequency signal transmits, peep the image finder.

Background technology

When in medical diagnosis multiple intravital lumen form organs such as stomach, intestinal, bladder being checked, endoscope is the inspection utensil of using always.Endoscope commonly used at present mostly is the version that directly is connected with the operation control structure through wire transmission structures such as photoelectricity Conductive fibers; not only staff's sensation when operation is inconvenient; the position that this endoscope can be checked through and/or the degree of depth also are very restricted because of wired form transmission structure of its connection, and the inspection utensil of while this kind version also regular meeting brings tangible discomfort or misery for the patient who is checked.

The utility model content

According to above-mentioned situation, this utility model will provide a kind of available wireless type to peep the image finder in medical, both made things convenient for staff's operation, also can eliminate and be checked that patient's does not accommodate misery, but also can make checked not for and/or the degree of depth no longer limited, and help improving the display effect of image, improve the quality of checking.

Peep the structure of image finder in the radio-type of the present utility model, be in having the closure casing of transparent part, to be provided with battery structure, be respectively arranged with luminous lighting structure of powering and the photosensitive sensor that is combined with optical lens with the corresponding position of this transparent part by battery structure, photosensitive sensor links with the imaging signal processing circuit that has the signal emitting structural, and each circuit structure provides operating current by battery structure.Because the image optics conversion of signals that photosensitive sensor is absorbed in can the intracoelomic cavity pipe organ sites with its place becomes the signal of telecommunication, particularly adopted CMOS (complementary metal oxide semiconductors (CMOS)) photoelectric sensor, or CCD (charge-coupled image sensor) photoelectric sensor that in digital camera, widely uses at present or other form photoelectric sensor with A/D translation function, change the image light signals of absorbing into analog electronic signal and also can further be converted to digital signal afterwards, handle and transmit out through corresponding signal processing circuit again by the wireless transmit structure of signal transmitting antenna form, can adopt the technology and the mode of routines such as similar television reception to receive and handle then through being arranged at external corresponding receiver structure, and, observe for operator at the image that demonstrates on the appropriate display structure after being reduced.For example, to peep the image finder in above-mentioned with after the mode of swallowing is in body is sent in the oral cavity, can progressively move forward with the autonomy wriggling of successively each several part histoorgan and by whole digestive tract, thereby the situation in the whole digestive tract from esophagus to rectum can be absorbed into picture signal continuously and send out, observe for operator, not only made things convenient for operation, and can observe present ordinary construction endoscope fully can't be deeply and the detailed pathological changes situation at the position of arriving.Signal through digitized processing can also make shown reduction image effect even more ideal.

For ease of the subject is sent in the body peeping the image finder in above-mentioned with oral way, said closure casing can be adopted as the capsule form that is easy to swallow in the said structure.

In said structure, even more ideal for making to the picked-up effect of image, the more suitable employing of said luminous lighting structure be white light-emitting diodes.

In said structure, said imaging signal processing circuit can useful multiple choices.For example, available employing in this imaging signal processing circuit than one of simple form, be to adopt at present existing commercially available ASIC integrated circuit, the LC oscillating circuit that has two mutual inductance forms in its structure, wherein the video signal input terminal from photosensitive sensor is connected with elementary LC oscillating circuit; The signal output of secondary LC oscillating circuit is connected with the signal emitting structural through structure for amplifying; Wherein said this structure for amplifying generally can adopt the audion commonly used with enlarging function.Enter the elementary LC oscillating circuit of this signal processing circuit by the video signal that photosensitive sensor absorbed, and in secondary LC oscillating circuit, produce corresponding induced oscillation signal, after structure for amplifying is enlarged into certain intensity and bandwidth, promptly launch by the signal emitting structural.

Peep the image finder in this utility model said structure owing to no longer have the wire transmission syndeton of the property inserted such as conduction optical fiber, not only the position that can allow to be checked through and/or the degree of depth no longer are restricted, and employing is that radio frequency signal sends out with the image transitions of being absorbed, by the mode of observing after corresponding receiver devices reception and the reduction, also help making the raising and convenient use of observed pictorial display definition, and owing to removed the wire transmission structure that is connected in the conventional equipment, had undamaged Noninvasive advantage, greatly alleviated or can eliminate fully patient's discomfort in the process of being checked or pain sensation.

Below with reference to the embodiment of accompanying drawing and instantiation, foregoing of the present utility model is described in further detail.But this should be interpreted as that the scope of the above-mentioned theme of this utility model only is confined to following example.
