The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
As shown in Figure 1, the self-service biopsy integrated device of scope, comprise electronic gastroscope main body 1, photoconduction flexible pipe 8, one end of electronic gastroscope main body 1 is provided with snake bone pipe 2, the front end of this snake bone pipe 2 is rotatable scope 3, in electronic gastroscope main body 1, be also provided with biopsy mouth 4, liquor charging switch 5, attract button 6 and angular adjustment valve 7, and this electronic gastroscope main body 1 is also connected with one end of photoconduction flexible pipe 8, the other end of photoconduction flexible pipe 8 is also provided with plug 9; In described snake bone pipe 2, be provided with control line, holding wire, suction catheter and liquid pushing tube, in electronic gastroscope main body 1, be also provided with dismountable biopsy device, this biopsy device is between angular adjustment valve 7 and snake bone pipe 2, by being provided with biopsy device, the present invention is changed into and can carry out biopsy and HP measuring ability from doing Gastroscopy, realized gastroscope, biopsy is integrated.
Further, described biopsy device comprises the pedestal 10 being removably connected in electronic gastroscope main body 1, is arranged on pedestal 10 and has the Flexible rule case 11 of opening, and these Flexible rule case 11 opening parts are also provided with the third channel 16 for being connected with biopsy mouth 4; In described Flexible rule case 11, be provided with the biopsy forceps that one end is fixed on pedestal 10, the other end is positioned at third channel 16.In order better to realize the present invention, described biopsy device also comprises the detection bottle 12 being arranged on pedestal 10 for detection of tissue HP, and be arranged on pedestal 10 for storing the holding bottle 13 of tissue, described holding bottle 13 is detachably arranged on pedestal 10; These Flexible rule case 11 opening parts be provided with for detect bottle 12 first passages that are connected 14, and the second channel 15 for being connected with holding bottle 13; Described holding bottle 13 is detachably arranged on pedestal 10.The present invention is deposited biopsy forceps to be placed in Flexible rule case by tape measure principle, and reduce biopsy forceps space and take up an area, and the situation of having avoided causing because biopsy forceps is long troublesome poeration; The present invention simultaneously can carry out HP detection and storage to tissue immediately after carrying out biopsy tissue, do not need as prior art just to carry out HP detection and storage afterwards by biopsy forceps is separated with gastroscope, shorten widely the clinical activity duration, alleviated medical personnel's labor intensity.
In addition, biopsy forceps of the present invention comprises the action bars 17 being fixed on pedestal 10, is connected and is enclosed within movably the slip ring 18 on action bars 17, and pass through the binding clip 20 that outer tube 19 is connected with action bars 17 with action bars 17 one end; In described outer tube 19, be provided with the steel wire that one end is connected with binding clip 20, the other end is connected with slip ring 18 through action bars 17, one end that this outer tube 19 is connected with action bars 17 is arranged at the interior center of Flexible rule case 11, and in this end outside, be also fixedly connected be useful on rotation outer tube 19 make it hover above the rotation disc 21 in Flexible rule case 11, the other end of outer tube 19 is positioned at third channel 16, and binding clip 20 is positioned at third channel 16 outsides.The present invention hovers above the outer tube of biopsy forceps in Flexible rule case, and by rotation disc, control the folding and unfolding of outer tube, certain outer tube of the present invention also can adopt manual folding and unfolding, owing to being provided with, lead to specially the passage that detects bottle and holding bottle simultaneously, binding clip can be exposed to outside, avoid being organized in situation about dropping accidentally and occurred.
A side inwall away from first passage mouth in third channel 16 of the present invention is provided with for the first shell fragment 22 to first passage mouth by binding clip 20 bullets, on a side inwall away from second channel mouth in described third channel 16, be also provided with for the second shell fragment 23 to second channel mouth by binding clip 20 bullets, described the second shell fragment 23 is between the first shell fragment 22 and Flexible rule case 11.Above-mentioned setting can rotated rotation disc when outer tube is taken in Flexible rule case, by corresponding shell fragment by binding clip bullet in corresponding passage, to carry out corresponding HP detection and storage.
Further, in described detection bottle and holding bottle, all fill corresponding liquid, and be prior art, therefore not in this narration, in order to guarantee that the liquid detecting in bottle and holding bottle can not spill, so be equipped with sealing film at the bottle mouth position that detects bottle and holding bottle, this thin film can be inserted by binding clip broken, can not affect normal detection and storage.
The present invention is when carrying out Clinical detection, in the time of need to carrying out biopsy, without medical personnel as prior art, control gastroscope, another medical personnel control biopsy, the present invention only needs medical personnel just can control gastroscope and biopsy simultaneously, patient's tissue is clamped and got, after pincers take into, can carry out immediately HP detection, and can store very easily after detecting, easy to operate, can waste of manpower resource, efficiency is high, is suitable for promoting the use of.
Biopsy device of the present invention is removable being installed in electronic gastroscope main body in addition, after whole operation completes, only biopsy device need be taken off from electronic gastroscope main body, to electronic gastroscope disinfection, just can continue to use, biopsy device is disposable, certainly also can carry out continuing to use after comprehensive repeatedly sterilization to biopsy device again.
When the present invention uses, first biopsy device is installed in electronic gastroscope main body, then proceeds as follows: first plug is inserted to plate and switch on power, open display screen, medical personnel show the image transmitting of observation the snake bone pipe front end of gastroscope by scope thereupon in human oral cavity stretches into body in outside receptor again at display screen, stomach or digestive tract are observed, when invention pathological tissues, adjust the angle of scope and the position of snake bone pipe to can observe clearly the position of pathological tissues, subsequently by the binding clip of biopsy forceps from biopsy mouth and extend into pathological tissues place and clamp and get pathological tissues, then clockwise rotating rotation disc is involved in outer tube and binding clip in Flexible rule case, when being drawn out from biopsy mouth after entering third channel, binding clip slows down velocity of rotation when binding clip approaches the first shell fragment, due to the elastic force of this shell fragment by its bullet to first passage mouth, rotating counterclockwise rotation disc stretches into binding clip in detection bottle and carries out HP mensuration again, after to be determined completing, continue to clockwise rotate rotation disc, when binding clip approaches the second shell fragment, because the elastic force of this shell fragment again can be by its bullet to second channel mouth, then rotating counterclockwise rotation disc stretches into binding clip in holding bottle pathological tissues is deposited in holding bottle, then will clockwise rotate rotating disk shifts out binding clip in holding bottle income Flexible rule case, finally holding bottle is taken off and carries out follow-up stores processor from pedestal.
According to above-described embodiment, just can realize well the present invention.What deserves to be explained is; under prerequisite based on said structure design, for solving same technical problem, even if some that make in the present invention are without substantial change or polishing; the essence of the technical scheme adopting is still the same with the present invention, therefore it also should be in protection scope of the present invention.
