Description
Technical field
This utility model relates to technical field of medical instruments, especially relates to a kind of fast-type disposable endoscope entry needle.
Background technology
Endoscope is a pipe being equipped with light, and it can enter gastric or enter in body through other natural hole by direct oral cavity.Utilize endoscope can see the pathological changes that X-ray can not show, therefore it is medical apparatus and instruments conventional in current clinical conditions, and medical personnel are by stretch into equipment head and conduit part in patient thus to observe it through eyepiece.Meanwhile, scope is also furnished with auxiliary facilities and can immediately carries out sampling while observation, treat or operation etc.Entry needle is one of ingredient very important in therapeutic endoscopy, its in clinical course to cavity organization's liquid medicine injection.Such as, the ulcer in digestive tract can be observed by endoscope doctor or swell and stay, make best therapeutic scheme accordingly.
Endoscope-use entry needle in currently available technology has following basic structure: injection needle point is connected with tube for transfusion, tube for transfusion is fixed on needle stand movable pipe, by pushing, movable pipe controls out, the withdraw of the needle, and by tube for transfusion, needle point to chamber tissue injection medicinal liquid.Conventional needle stand is moved by moving-limiting pipes such as fit clearances, prevents needle point from returning, but this technical method manipulation difficulty, and locking effect is not obvious.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the problem of the easy back stitching of syringe that Microendoscopic uses in prior art, provide a kind of fast-type disposable endoscope entry needle.
This utility model solves the technical scheme that its technical problem adopts: a kind of fast-type disposable endoscope entry needle, comprise interior pipe, outer tube, shell, syringe needle and syringe adapter, described syringe needle is arranged on interior pipe one end, described syringe adapter is arranged on the interior pipe other end, described interior pipe is arranged within the outer tube, described outer tube one end is fixedly connected with shell, described outer surface of outer cover circumference is provided with some shell fragments, described shell fragment end is provided with buckle, described outer surface of outer cover circumference has some draw-in grooves corresponding with buckle, the outer surface of described shell is arranged with annulus, described inner tube outer surface is also arranged with spring, described spring one end is fixed on inner surface of outer cover, the described spring other end is fixed on inner tube outer surface.
In order to locate the position of annulus, the outer surface of described shell is provided with the first projection, and described annulus is located between the first projection and shell fragment.
In order to make annulus not depart from shell fragment in the process of movement, the end of described shell fragment is provided with for stop annulus second protruding.
In order to make to manage in the closer laminating of buckle, make its more fixing interior pipe, the material of described buckle is rubber.
During use, inwardly promoted by syringe adapter, syringe needle inserts affected part, pull annulus to move to buckle direction, treat that annulus props up the second projection, buckle is fitted through draw-in groove and interior pipe, in stoping, pipe moves, and namely effectively prevent back stitching, now spring is in confined state; Be connected with syringe by syringe adapter, to affected part injection injection liquid, after having injected, back promoted by annulus, to annulus and the first projection contacts, shell fragment flicks, and drives buckle to depart from interior pipe, recoil of spring, drives syringe needle to shift out affected part.
The beneficial effects of the utility model are: this utility model structure is simple, use is quick, saves time, and reduces patient suffering.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is two-dimentional sectional view of the present utility model.
In figure: 1. pipe in, 2. outer tube, 3. shell, 4. syringe needle, 5. syringe adapter, 6. shell fragment, 7. buckle, 8. draw-in groove, 9. annulus, 10. spring, 11. first is protruding, and 12. second is protruding.
Detailed description of the invention
The utility model is described in more detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
A kind of fast-type disposable endoscope entry needle as shown in Figure 1, comprise interior pipe 1, outer tube 2, shell 3, syringe needle 4 and syringe adapter 5, described syringe needle 4 is arranged on interior pipe 1 one end, described syringe adapter 5 is arranged on interior pipe 1 other end, described interior pipe 1 is arranged in outer tube 2, described outer tube 2 one end is fixedly connected with shell 3, described shell 3 outer surface circumference is provided with some shell fragments 6, described shell fragment 6 end is provided with buckle 7, described shell 3 outer surface circumference has some draw-in grooves 8 corresponding with buckle 7, the outer surface of described shell 3 is arranged with annulus 9, described interior pipe 1 outer surface is also arranged with spring 10, described spring 10 one end is fixed on shell 3 inner surface, described spring 10 other end is fixed on interior pipe 1 outer surface.
In order to locate the position of annulus 9, the outer surface of described shell 3 is provided with the first projection 11, and described annulus 9 is located between first protruding 11 and shell fragment 6.
In order to make annulus 9 not depart from shell fragment 6 in the process of movement, the end of described shell fragment 6 is provided with the second projection 12 for stopping annulus 9.
In order to make pipe 1 in the closer laminating of buckle 7, make its more fixing interior pipe 1, the material of described buckle 7 is rubber.
During use, inwardly promoted by syringe adapter 5, syringe needle 4 inserts affected part, pull annulus 9 to move to buckle 7 direction, treat that annulus 9 props up the second projection 12, buckle 7 is fitted through draw-in groove 8 and interior pipe 1, in stoping, pipe 1 moves, and namely effectively prevent back stitching, now spring 10 is in confined state; Be connected with syringe by syringe adapter 5, to affected part injection injection liquid, after having injected, back promoted by annulus 9, contact to annulus 9 with first protruding 11, shell fragment 6 flicks, and drives buckle 7 to depart from interior pipe 1, spring 10 resilience, drives syringe needle 4 to shift out affected part.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
