The photographing means also includes a light and electric adapter and an image processing display device connected with an output end of light and electric adapter. The image processing display device includes a disposable shell body of the LCD display, and the shell body is inserted with an image processing circuit connected with the light and electric adapter output end therein. The image processing circuit output end is connected with the LCD display. The utility model has advantages of reasonable structure, convenient using, small volume, which is not only convenient to bring, but also solves the problem of a plurality of cables provided between the means, and avoids the damage with the service life enlarged.

Description

The portable electronic endoscope camera head

Technical field

This utility model relates to the fujinon electronic video endoscope camera technique, specifically is a kind of portable electronic endoscope camera head.

Background technology

Endoscope is a kind of medical optical instrument, and the history in 200 years has been arranged so far.Along with developing rapidly of advanced science and technology, the kind of endoscope and level have also had the progress of advancing by leaps and bounds, and develop into fujinon electronic video endoscope and ultrasonic electronic mirror from hard tube mirror and fibrescope.Because the external diameter of fujinon electronic video endoscope is thinner, image is more clear and directly perceived, easy to operate, Wicresoft, misery is little even noinvasive is painless characteristics are arranged when implement checking with operation, therefore be widely used in occupying the leading position in the operation endoscope just gradually in the inspection and operation of gastrointestinal tract, esophagus, pancreas, biliary tract, abdominal cavity, respiratory tract, urinary system, gynaecopathia.But present most of hospital is employed and the matching used picture pick-up device of fujinon electronic video endoscope all is the integrated mode of relative complex, and volume is bigger, moves inconvenient, equipment can only use in fixed operating room, the equipment room cable is numerous, damages easily, and the maintenance cost costliness.

Summary of the invention

There are problems such as cable is numerous, fragile between big, mobile inconvenience of volume and device in this utility model in order to solve existing electronic endoscope image pick-up device, and a kind of portable electronic endoscope camera head is provided.

This utility model is to adopt following technical scheme to realize: the portable electronic endoscope camera head, comprise photoelectricity adapter and the image processing display that is connected in photoelectricity adapter outfan, described image processing display comprises the portable housing that is provided with LCD display, the built-in image processing circuit that links to each other with photoelectricity adapter outfan of housing, described image processing circuit comprises the FPGA control chip, the Video processing that controlled ports links to each other with the control port of FPGA control chip and A/D module and D/A and video encoding module, and be serially connected with memorizer FIFO between Video processing and A/D module and D/A and the video encoding module, VRAM, memorizer FIFO, VRAM links to each other with the Data Transmission Controlling port of FPGA control chip respectively, memorizer FIFO is connected with the interface microcontroller that is used for the function expansion, memorizer VRAM is connected with the start reseting port, the input of Video processing and A/D module links to each other with the outfan of photoelectricity adapter, and the outfan of D/A and video encoding module is connected with LCD display.

During use, photoelectricity adapter and endoscope's tail end are fixed, simultaneously at the fixing portable light source in the light source junction of endoscope, when specifically implementing inspection/operation, the image situation of inspection/operation transforms through the photoelectricity adapter, and transfers to the image processing circuit processing, after the processing, shown by LCD display, make doctor/patient can observe the image of endoscopic surgery by LCD display.Compared with prior art, this utility model has fundamentally changed the defective that medical endoscope camera head inconvenience is in the past moved, but the routine examination of clinical each section of widespread usage and operation can be implemented to check and the hands art between any relative aseptic operation; The patient can participate in observation directly by LCD display, can play a positive role to the intense strain of eliminating the patient, inspection interest and the confidence that improves the patient.The photoelectricity adapter is existing known products, comprise camera lens, light filter, CCD (charge-coupled device), and the drive clock of CCD is controlled by the FPGA control chip of image processing circuit.The Video processing of described image processing circuit and A/D module and D/A and video encoding module are the existing known products that sell in market.FPGA control chip and memorizer FIFO, VRAM are existing known products.

This utility model is rational in infrastructure, and is easy to use, and volume is little, not only easy to carry, and solved the numerous problem of cable between device, avoids damaging, and improved service life.
