Description

Self-storage endoscope

Technical field:

This utility model relates to the endoscope that is applied in the medical treatment, particularly a kind of profile such as same pill capsule, and in the body of can swallowing, the intestinal depths that reaches is to peep the endoscope of function in realizing.

Background technology:

Pill endoscope is a kind of high-tech product that development in recent years is got up, profile such as same pill capsule, can swallow in the body, it not only can arrive the unapproachable intestinal locations deep of conventional endoscope, and compare with traditional endoscope, it is also much smaller to the misery that patient brings.At present, this product is made up of shooting ball and wireless image receiving system two large divisions.Wherein, the shooting ball has comprised photographic head, image signal radio emitter, power autonomous, and ball shape housing.The shooting ball is promoted to advance in vivo by human muscular tissue as food after entering human body, takes image in the human body when advancing, and the image that obtains need be transmitted into human external by wireless transmitter.The wireless image receiving system disposes with oneself, is used for reception, storage and the demonstration of image, finishes the inspection of human body.The problem that this form exists comprises:

1, because the shot image data amount is very big, for example the true color image of one 100,000 pixel approximately is the 200000 bytes data volumes of (byte comprises 8 binary digits), unify 160 myriabits (1.6Mbit) approximately, for this reason, wireless communication apparatus emission with the 1M bit rate, want just can finish in two seconds the emission of the true color image of one 100,000 pixel approximately, once check the image that approximately will take more than 20,000 width of cloth and finish, obviously, the a large amount of electric energy of this process need consumption is used for the image that the wireless telecommunications device is launched shooting, thereby power configuration is had higher requirement.

2, because high speed micro radio image emissions circuit is set, increased the complexity of system, occupation mode complexity, valuable product.

3, owing to need configuration with oneself, the wireless image receiving system can not many people use simultaneously, obviously because utilization rate is restricted, has increased the use cost of equipment, especially when being the generaI investigation of scale such as health check-up, the man-to-man occupation mode of wireless image receiving system is not suitable on work efficiency very much.

4, because the radio wave of micro radio image emissions circuit emission is subject to disturb, and the reliability of image transmission is low, this problem is particularly outstanding in the urban environment that the current wireless electric wave crowds.

The utility model content:

This utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of effectively simplified system to constitute, simplify occupation mode, reduce use cost, and the self-storage endoscope of raising functional reliability, shooting process does not need to carry out with external equipment the transmission of view data, but the direct inside that shot image data is stored in endoscope apparatus, after using end, the data message that will be stored in wherein by metal electrode takes out, and is finished the processing of data message by supporting enforcement.

The technical scheme that this utility model technical solution problem is adopted is:

This utility model adopts ball shape closure casing, and an end of housing is the transparent body, and in housing, an end that is positioned at its transparent body place is an image unit;

Construction features of the present utility model is in housing, the system that is equipped with image unit constitutes and comprises: signal processing circuit, data storage cell and include the auxiliary unit of Switching Power Supply, in the outside of housing, be provided for the metal electrode of signal transmission around housing; Wherein,

Image unit, the control signal of received signal treatment circuit is carried out endoscopic picture and is taken, and picture signal is sent to signal processing circuit immediately;

Data storage cell is peeped the view data of accepting at any time in the process from signal processing circuit and is carried out interior storage, and finishes the back in the interior process of peeping and export all images data of its storage by metal electrode in once complete.

Construction features of the present utility model also is:

Signal processing unit adopts high-speed low-power-consumption microprocessor IC2, and image unit is CMOS SENSOR chip IC 1 or CCD chip, and data storage cell adopts Flash storage chip IC3, ferroelectric formula memorizer or static RAM (SRAM) memorizer; Described microprocessor IC2 produces image unit IC1 required sequential and control command under programme-control, and sends to the pin of the corresponding label of image unit IC1 by its I/O pin; View data after microprocessor IC2 will handle is transferred among the pin-saving chip IC3 by serial device interfaces line MISO, MOSI, SPICLK.

Along with the various types of miniature data storages of the development of technology drop into application in a large number, and volume is more and more littler, memory capacity is increasing, the little 11mm * 15mm * 1mm that arrives of volume that the TranFlash storage card that for example uses on the mobile phone is present, memory capacity has reached several GByte, such volume and memory capacity can satisfy the image that the storage of image ball is taken, for enforcement of the present utility model provides sound assurance.Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, this utility model is stored in device inside with shot image data, thereby no longer needs configuration power consumption big, complex structure, and the high speed micro radio image emissions circuit that technical difficulty is big greatly reduces the complexity of system.

2, this utility model does not need to be each user configuration image receiving system, greatly reduces equipment cost, has reduced cost of use, is widely used in the extensive conditions of having created of generally investigating such as health check-up for it.

3, this utility model is owing to directly be kept at device inside with view data, avoided existing pill endoscope utilize the radio wave transmissions image problem that is interfered easily, the reliability that has improved system works, the image quality loss of having avoided wireless figure line transmission or communication information compression to cause simultaneously.

4, this utility model can be preserved a large amount of high-resolution, high-quality view data because the internal storage capacity is huge, therefore can take and preserve the picture far above existing pill endoscope quality, helps improving the effect of medical inspection.Peep the restriction that is subjected to the wireless telecommunications bandwidth in the existing pill and be difficult to transmit high-resolution, high-quality image.
