Abstract
This utility model relates to a kind of new disposable endoscope entry needle, comprise interior pipe, outer tube, shell, syringe needle and syringe adapter, syringe needle is arranged on interior pipe one end, syringe adapter is arranged on the interior pipe other end, interior pipe is arranged within the outer tube, and outer tube one end is fixedly connected with shell, is provided with circular unidirectional button in shell, unidirectional button is formed by some fanning strip circumference uniform distributions, and syringe adapter outer surface is provided with projection; This utility model structure is simple, easy to operate, effectively solves the problem of back stitching, makes patient avoid again the misery of contact pin.
Description
Technical field
This utility model relates to technical field of medical instruments, especially relates to a kind of new 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 new disposable endoscope entry needle.
This utility model solves the technical scheme that its technical problem adopts: a kind of new 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, circular unidirectional button is provided with in described shell, described unidirectional button is formed by some fanning strip circumference uniform distributions, and described syringe adapter outer surface is provided with projection.
In order to make syringe tube joint more easily insert unidirectional button, the junction of described interior pipe and syringe adapter is provided with transition slope.
During use, pushing syringe joint, under the effect of transition slope, syringe adapter more easily promotes, and when projection contacts is to unidirectional button, stops pushing syringe joint, and syringe adapter drives syringe needle to insert affected part; Syringe adapter is static under the effect of unidirectional button, and favourable prevents back stitching, to be injected complete after, together extract.
The beneficial effects of the utility model are: this utility model structure is simple, easy to operate, effectively solves the problem of back stitching, makes patient avoid again the misery of contact pin.
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;
Fig. 2 is the top view of the unidirectional button of this utility model.
In figure: 1. pipe in, 2. outer tube, 3. shell, 4. syringe needle, 5. syringe adapter, 6. unidirectional button, 7. protruding, 8. transition slope, 9. fanning strip.
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 new 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, syringe needle 4 is arranged on interior pipe 1 one end, syringe adapter 5 is arranged on interior pipe 1 other end, interior pipe 1 is arranged in outer tube 2, and outer tube 2 one end is fixedly connected with shell 3, is provided with the unidirectional button 6 of circle as shown in Figure 2 in shell 3, unidirectional button 6 is formed by some fanning strip 9 circumference uniform distributions, and syringe adapter 5 outer surface is provided with protruding 7.
In order to make syringe tube joint 5 more easily insert unidirectional button 6, interior pipe 1 is provided with transition slope 8 with the junction of syringe adapter 5.
During use, pushing syringe joint 5, under the effect of transition slope 8, syringe adapter 5 more easily promotes, and when protruding 7 touch unidirectional button 6, stop pushing syringe joint 5, syringe adapter 5 drives syringe needle 4 to insert affected part; Syringe adapter 5 is static under the effect of unidirectional button 6, and favourable prevents back stitching, to be injected complete after, together extract.
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.
