Abstract
The utility model relates to the field of interventional treatment equipment and particularly to a dual purpose interventional puncture needle. The dual purpose interventional puncture needle comprises a needle head, a needle body, a needle handle and a needle core; a branch pipe is arranged on the needle body; a ventilation pipe which is communicated with the branch pipe is arranged inside the needle body; the front end of the ventilation pipe is align to the front end of the needle body; the front portion of the needle core is provided with a sealing ring; a blocking ring is arranged inside the needle handle; the external wall at the rear end of the needle body is provided with threads I; the internal wall of the needle handle is provided with threads II which are matched with the threads I. The dual purpose interventional puncture needle has the advantages of being free of blood outflow during the process of guiding in guide wires due to the fact that the ventilation pipe which is used for balancing air pressure is arranged and accordingly protecting medical workers and protecting the hospital operating environment; achieving dual purpose due to the needle body and the needle handle which are connected through threads; being simple, precise and reasonable in structure and suitable for popularization.
Description
Technical field
This utility model relates to interventional therapy apparatus field, more specifically a kind of dual-purpose insertion puncture needle.
Background technology
Interventional therapy is listed as the large pillar subject of medical field three with internal medicine, surgery, and puncture needle is often used in intervention in blood vessel, one type of puncture needle is guiding guide wires therein, another kind is used as mozzle, the effect of puncture needle is in the market more single, the not combination of two kinds, and for the puncture needle of guiding guide wires therein type is easy to flow out blood and pollutes in extracting nook closing member and inserting the process of seal wire.
For this problem, application number a kind of interventional guide wire lead-in device that has been 201220198911.6 Patent Application Publication, it comprises needle body, needle handle and nook closing member, it is provided with arm on needle handle, branch pipe wall is provided with soft rubber sleeve, when carrying out interventional therapy to patient, the nook closing member of moving out inwardly pushes seal wire from arm simultaneously, and by soft rubber sleeve sealing seal wire around, and in use, in the nook closing member of moving out, in arm, inwardly push seal wire, because the surrounding of nook closing member leaves space (otherwise seal wire cannot push), therefore having equally a large amount of blood flows out, medical worker and operating environment are polluted.
It is more than weak point of the prior art.
Summary of the invention
Goal of the invention of the present utility model is, for above weak point of the prior art, to provide a kind of guiding guide wires therein and tapping dual-purpose puncture needle, and in the process of guiding guide wires therein, avoids blood to flow out.
This utility model is achieved through the following technical solutions:
A kind of dual-purpose insertion puncture needle, comprise syringe needle, needle body, needle handle and nook closing member, described needle body is provided with arm, in described needle body, be provided with the breather being communicated with arm, the front end of described breather is concordant with the front end of needle body, and the front portion of described nook closing member is provided with sealing ring, in described needle handle, is provided with and stops circle, the outer wall of described needle rear end is provided with screw thread I, and the inwall of described needle handle is provided with the screw thread II matching with screw thread I.
Due to the front end of breather and the front end of needle body concordant, in the process that nook closing member exits, negative pressure in needle body, therefore there is the inside make-up gas of breather, guarantee inner pressure balance, can not cause blood to flow out, and screw thread I on needle rear end outer wall can also be connected with mozzle, screw thread I can also play the friction that increases mozzle and needle body, plays the effect of fixed diversion pipe, and a pin is dual-purpose.
Above-mentioned breather is comprised of dividing plate and needle body wall, and described dividing plate is provided with the hole being communicated with arm, and this hole pushes for seal wire.
The width in above-mentioned hole is less than the width of sealing ring, in the process exiting, because the width of sealing ring is greater than hole, can not cause sealing ring to snap in hole at nook closing member.
The angle of above-mentioned arm and needle rear end is 15-30 °, and angle of inclination is little is conducive to pushing of seal wire.
Optimize, the angle of above-mentioned arm and needle rear end is 30 °.
Above-mentioned branch pipe wall is provided with soft rubber sleeve, due to sealing seal wire.
The beneficial effects of the utility model are: by being provided for the breather of equilibrium air pressure; make without blood flow, to go out in this utility model guiding guide wires therein process; thereby protected medical worker; also protected the operating environment of hospital; and the needle body being threaded connection and needle handle can make puncture needle one pin dual-purpose; this utility model is simple in structure, rigorous, reasonable, is applicable to promoting.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation;
Fig. 2 is structural representation after this utility model needle body and needle handle decompose;
Fig. 3 is this utility model breather sectional view;
In figure: 1-syringe needle, 2-needle body, 3-needle handle, 4-nook closing member, 5-arm, 6-breather, 7-sealing ring, 8-stops circle, 9-screw thread I, 10-screw thread II, 11-dividing plate, 12-hole, 13-soft rubber sleeve.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, be described further, so that those skilled in the art can better understand this utility model, but therefore do not limit this utility model.
A kind of dual-purpose insertion puncture needle, comprise syringe needle 1, needle body 2, needle handle 3 and nook closing member 4, described needle body 2 is provided with arm 5, in described needle body 1, be provided with the breather 6 being communicated with arm 5, the front end of described breather 6 is concordant with the front end of needle body 2, the front portion of described nook closing member 4 is provided with sealing ring 7, in described needle handle 3, be provided with and stop circle 8, stop that circle 8 is for preventing that nook closing member 4 from all exiting, the outer wall of described needle body 3 rear ends is provided with screw thread I 9, and the inwall of described needle handle 3 is provided with the screw thread II 10 matching with screw thread I 9.
Above-mentioned breather 6 is comprised of dividing plate 11 and needle body 2 walls, and described dividing plate 11 is provided with the hole 12 being communicated with arm 5, this hole 12 pushing for seal wire.
The width in above-mentioned hole 12 is less than the width of sealing ring 7, in the process exiting, because the width of sealing ring 7 is greater than hole 12, can not cause sealing ring 7 to snap in hole 12 at nook closing member 4.
