Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of shell fragment locking 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 very useful to doctor.Such as, the ulcer in digestive tract can be observed by endoscope doctor or swell and stay, make best therapeutic scheme accordingly.
Existing multiple Microendoscopic entry needle has the operating portion of the elongated insertion section that can be inserted in endoscope path way and the cardinal extremity being connected to this insertion section usually, insertion section comprises dual pipe, and this dual pipe has outer tube and is inserted in this outer tube in mode freely of retreating manages.Aforesaid operations portion carries out the operation that above-mentioned outer tube is retreated, and is provided with the syringe needle of hollow in the front end of interior pipe.Cardinal extremity is generally connected with syringe, and pipe in being come in and gone out by liquid, needs to fix after existing syringe is connected with cardinal extremity, just can be convenient to injecting fluid.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the fixation problem of syringe and cardinal extremity in prior art, and this utility model provides a kind of shell fragment locking type disposable endoscope entry needle.
This utility model solves the technical scheme that its technical problem adopts: a kind of shell fragment locking type disposable endoscope entry needle, comprise interior pipe, be connected to the syringe needle of interior pipe front end, be connected to the boost tube of interior pipe rear end, be enclosed within the outer tube outside interior pipe, be enclosed within the protecting pipe outside boost tube, the front end of protecting pipe is fixedly connected with the rear end of outer tube, the rear end of protecting pipe is fixedly connected with connection overcoat, the rear end connecting overcoat is provided with spacing ring, also comprise the core bar with spacing ring clamping, described core bar first half has the sleeve coordinated with spacing ring inner ring, sleeve outer ring is symmetrically arranged with shell fragment, the outer surface of one end of the close spacing ring of shell fragment has projection, spacing ring inner ring is symmetrically arranged with the locating slot with male cooperation, the inner ring of spacing ring near one end of core bar has flared section, flared section can be held shell fragment and enter.
Further, particularly, for the ease of core bar guiding, described sleeve outer ring is symmetrical arranged gathering sill, and spacing ring inner ring is symmetrically arranged with the gib block of the protrusion coordinated with gathering sill.
For the ease of core bar and spacing ring clamping, described shell fragment is end of upspringing near one end of spacing ring, and the other end and sleeve integrative-structure, described projection is arc-shaped.
The beneficial effects of the utility model are, shell fragment locking type disposable endoscope entry needle of the present utility model, fixes clamping by the projection of shell fragment end by core bar and spacing ring, and location structure is reasonable, and simplicity of design, facilitates doctor to operate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.

Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail 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.
As Figure 1-3, it is embodiment of the present utility model, comprise interior pipe 3, be connected to the syringe needle 1 of interior pipe 3 front end, be connected to the boost tube 4 of interior pipe 3 rear end, be enclosed within the outer tube 5 outside interior pipe 3, be enclosed within the protecting pipe 6 outside boost tube 4, the front end of protecting pipe 6 is fixedly connected with the rear end of outer tube 5, the rear end of protecting pipe 6 is fixedly connected with and connects overcoat 7, the rear end connecting overcoat 7 is provided with spacing ring 8, also comprise the core bar 9 with spacing ring 8 clamping, core bar 9 first half has the sleeve 91 coordinated with spacing ring 8 inner ring, sleeve 91 outer ring is symmetrical arranged gathering sill 92, sleeve 91 outer ring is symmetrically arranged with shell fragment 93, the outer surface of one end of the close spacing ring 8 of shell fragment 93 has protruding 931, spacing ring 8 inner ring is symmetrically arranged with and protruding 931 locating slots 82 coordinated, the inner ring of spacing ring 8 near one end of core bar 9 has flared section 83, flared section 83 can be held shell fragment 93 and enter.Sleeve 91 outer ring is symmetrical arranged gathering sill 92, and spacing ring 8 inner ring is symmetrically arranged with the gib block 81 of the protrusion coordinated with gathering sill 92.Shell fragment 93 is end of upspringing near one end of spacing ring 8, the other end and sleeve 91 integrative-structure, and protruding 931 in arc-shaped.
The cooperation of gathering sill 92 and gib block 81 is to make the stroke of shell fragment 93 towards locating slot 82, when sleeve 91 inserts in spacing ring 8, the projection 931 of shell fragment 93 extrudes through flared section 83, enter in spacing ring 8, after the projection 931 of shell fragment 93 proceeds to locating slot 82, extruding force disappears, and shell fragment 93 is upspring, projection 931 is headed in locating slot 82, thus position-limiting action.
Also garter spring can be set in spacing ring 8 outer ring as required, garter spring is positioned at a certain section of the outer ring of the spacing ring 8 that locating slot 82 extends forward, when needing to unload core bar 9, garter spring can be moved to spacing ring 8 rear end, locating slot 82 can be extruded time outside to locating slot 82, thus the projection 931 in extrusion elastic 93, core bar 9 can be extracted.
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.
