Abstract

The utility model discloses an endoscope which comprises a tube body and an endoscope head. The tube body is used for being inserted into the body, the endoscope head is arranged at the front end of the tube body, a sampling channel used for allowing sampling tongs to penetrate is formed in the tube body, and the endoscope further comprises an LED lamp which stretches to the front end of the tube body through the sampling channel. The LED lamp is adopted to replace an original light-guide fiber, a light source is directly arranged at the position of the endoscope head at the front end of the tube body, transmission attenuation of light in the light-guide fiber is avoided, meanwhile, compared with the light-guide fiber, a wire can be suitable for bending of various amplitudes, the endoscope is more flexible in use, after the repeated use, the wire can not be broken, the service life is long, and in addition, when the portions with different colors are observed, monochromatic light which enables the observation effect to be better can be selected.

Description

Endoscope

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of medical endoscope.

Background technology

Endoscope is a kind of by entering the medical apparatus and instruments of observing diseased region directly perceived in body, and it can observe the pathological changes that X ray can not show, therefore, comparatively conventional in medical diagnosis.

Endoscope generally forms by inserting body, objective lens, illuminator and finder etc., and more advanced also have image analysing computer processing system, and the image check of tract in perfect aspect intuitively, as gastroscope, intestinal sight glass etc.They all have, and volume is little, inspection is convenient, check the advantages such as directly perceived.In prior art, endoscope inserts human body by flexible body, to adapt to the scrambling of body cavities, objective lens is positioned at body front end, generally that optical fibers by being arranged in body is sent to check point by light, and when shades of colour different parts is observed in prior art, all adopt white light, for the position of some color, it is best that the observing effect of white-light illuminating can not reach.

Optical fibers has low-loss advantage, but because transmission range is far away, still has the phenomenon of light loss decay, and the image fault that causes observation or take, affects diagnostic result; Simultaneously, because the tract of human body mostly is irregularly shaped, optical fibers often needs crooked, and its characteristic causes it also cannot meet instructions for use completely, arrive some position, affected the motility that endoscope is used, in addition, along with the increase of access times, comparatively general phenomenon is that optical fibers fractures, cause the decay of brightness more serious, make observation or shooting results occur larger distortion, affect diagnostic result.

For above-mentioned deficiency, need to improve existing endoscope, overcome the shortcoming that decay appears in light in transmittance process, Bing Shi endoscope is in use unrestricted, operate more flexibly, also allow it can, because of too much not the damaging of access times, not increase the service life, when ，Shi endoscope throws light on to shades of colour position simultaneously, observing effect reaches best.

Utility model content

In view of this, this utility model provides a kind of endoscope, the mode that this endoscope transmits light to traditional optical fiber is improved, to reach the object of avoiding light to decay in transmittance process, simultaneously, this endoscope is used the impact that is not subject to body cavities irregular problem, easy to use and flexible, and long service life.

Endoscope of the present utility model, comprises for the body in insertosome and the endoscope head that is arranged at body front end, is provided with the sampling passage passing for sample pickup tongs in described body, also comprises and can extend by sampling passage the LED lamp of body front end.

Further, on described LED lamp, be connected with wire, wire free end is power taking plug;

Further, described power taking plug is USB interface;

Further, described LED lamp has four kinds, is respectively white light, red globe lamp, blue-ray light and green light lamp.

The beneficial effects of the utility model are: endoscope of the present utility model, comprise for the body in insertosome and the endoscope head that is arranged at body front end, in described body, be provided with the sampling passage passing for sample pickup tongs, also comprise and can extend by sampling passage the LED lamp of body front end, adopt LED lamp to replace original optical fibers, light source is directly arranged to the endoscope head place of body front end, avoided the transmission decay of light in optical fibers, simultaneously, wire is compared with optical fibers, can adapt to the bending of various amplitudes, make the use of endoscope more flexible, and repeatedly use and also can not cause wire to fracture, life in application is long, in addition, when different colours position is observed, can select to allow the better monochromatic light of observing effect.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, this utility model is further described.

Fig. 1 is this utility model structural representation;

Fig. 2 is the I place enlarged drawing of Fig. 1;

Fig. 3 is the A-A sectional view of Fig. 1.

The specific embodiment

Below with reference to Fig. 1 to Fig. 3, this utility model is elaborated, as shown in the figure: the endoscope of the present embodiment, comprise for the body 1 in insertosome and the endoscope head 2 that is arranged at body 1 front end, in described body 1, be provided with the sampling passage 3 passing for sample pickup tongs, this endoscope also comprises can extend by sampling passage 3 the LED lamp 4 of body front end, during use, first by body insertosome, the method that recycling sampling passage is put into according to sample pickup tongs extends body front end by LED lamp and throws light on, adopt LED lamp to replace existing optical fibers, light source is directly arranged to the endoscope head place of body front end, avoided the transmission decay of light in optical fibers, simultaneously, wire is compared with optical fibers, can adapt to the bending of various amplitudes, make the use of endoscope more flexible, and repeatedly use and also can not cause wire to fracture, life in application is long.

In the present embodiment, on described LED lamp 4, be connected with wire 5, wire 5 is through sampling passage 3 and being electrically connected to extraneous power supply by power taking plug, simple in structure, easy to implement.

In the present embodiment, described power taking plug is USB interface, directly by the USB interface power taking on endoscopic system computer, just can meet the electricity consumption requirement of LED lamp, without being equipped with in addition the article such as transformation plug, cost of manufacture is low, and the electric current and voltage that can reach due to USB mouth all, in safety range, has increased safety.

In the present embodiment, described LED lamp 4 has four kinds, is respectively white light, red globe lamp, blue-ray light and green light lamp, when different parts is checked, according to the color at this position, selects different light to throw light on, and can reach best observing effect.

Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although this utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
