Abstract

This utility model provides a kind of Thyroid puncture needle with negtive-pressure implement, mainly comprise piercing needle and syringe, syringe is arranged on the rear of piercing needle, feed liquor check valve is provided with between syringe and piercing needle, the sidewall of syringe front end is provided with steam vent, steam vent is provided with exhaust check valve, sidewall after steam vent is provided with the bell and spigot joint be communicated with syringe cavity, bell and spigot joint rear end is provided with negtive-pressure implement, the negtive-pressure implement device that is fixed is fixed on the top of syringe, is provided with piston, push rod successively and pushes away handle in syringe.The beneficial effects of the utility model are: this utility model structure is simple, medical worker is easier, time saving and energy saving when carrying out thyroid nodule and cyst suction operation to patient, when capsula glandulae thyreoideae liquid comparatively thickness time, negtive-pressure implement can be used to assist carry out, draw better effects if, because syringe is provided with feed liquor check valve and exhaust check valve, can prevent capsule liquid from flowing backwards, it is easy to use, swift to operate, has significant practicality.

Description

A kind of Thyroid puncture needle with negtive-pressure implement
Technical field
This utility model relates to a kind of puncture needle, particularly relates to a kind of Thyroid puncture needle with negtive-pressure implement.
Background technology
When thyroid nodule and cyst, puncture needle must be used to obtain Pathologic specimen to thyroid nodule puncture diagnose, or extraction is carried out to capsule liquid treat, therefore Thyroid puncture needle is an important armarium, in existing Thyroid puncture needle, when the liquid in thyroid cyst is thin, Thyroid puncture needle is used to be easy to take out, when capsula glandulae thyreoideae liquid comparatively thickness or to solid nodal-like enclosed mass time, often because negative pressure is not enough, and capsule liquid can not be extracted smoothly, or the sample size extracted is not enough, bring very large inconvenience to diagnosis and disease treatment.
Utility model content
The purpose of this utility model is to overcome weak point of the prior art, provides a kind of Thyroid puncture needle with negtive-pressure implement.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
A kind of Thyroid puncture needle with negtive-pressure implement, comprise: piercing needle and syringe, syringe is arranged on the rear of piercing needle, is provided with feed liquor check valve between syringe and piercing needle, the sidewall of syringe front end is provided with steam vent, and steam vent is provided with exhaust check valve.
Further, the sidewall after steam vent is provided with the bell and spigot joint be communicated with syringe cavity, bell and spigot joint rear end is provided with negtive-pressure implement, and the negtive-pressure implement device that is fixed is fixed on the top of syringe, is provided with piston, push rod successively and pushes away handle in syringe.
This utility model has following beneficial effect:
Thyroid puncture needle with negtive-pressure implement of the present utility model, its structure is simple, medical worker is easier, time saving and energy saving when carrying out thyroid nodule and cyst suction operation to patient, when capsula glandulae thyreoideae liquid is thicker, negtive-pressure implement can be used to assist and carry out, draw better effects if, because syringe is provided with feed liquor check valve and exhaust check valve, can prevent capsule liquid from flowing backwards, it is easy to use, swift to operate, there is significant practicality.
Accompanying drawing explanation
Fig. 1 is the thyroid needle needle construction front view with negtive-pressure implement provided by the utility model;
Symbol description:
1: piercing needle 2: syringe 3: feed liquor check valve 4: exhaust check valve
5: steam vent 6: fixture 7: bell and spigot joint 8: negtive-pressure implement
9: piston 10: push rod 11: push away handle
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
As a kind of embodiment of the present utility model, consult figure, a kind of Thyroid puncture needle with negtive-pressure implement, comprise: piercing needle 1 and syringe 2, syringe 2 is arranged on the rear of piercing needle 1, feed liquor check valve 3 is provided with between syringe 2 and piercing needle 1, the sidewall of syringe 2 front end is provided with steam vent 5, steam vent 5 is provided with exhaust check valve 4, sidewall after steam vent 5 is provided with the bell and spigot joint 7 be communicated with syringe 2 cavity, bell and spigot joint 7 rear end is provided with negtive-pressure implement 8, negtive-pressure implement 8 device 6 that is fixed is fixed on the top of syringe 2, piston 9 is provided with successively in syringe 2, push rod 10 and push away handle 11.
When the liquid in thyroid cyst is rare, syringe 2 is used just can directly to draw, when the liquid in thyroid cyst is thick or to solid nodal-like enclosed mass, syringe 2 is used just to be difficult to draw, negtive-pressure implement 8 can be communicated with draw thyroid again, and feed liquor check valve 3 and exhaust check valve 4 are set on syringe 2, the effect preventing capsule liquid from flowing backwards can be played.
In sum; this utility model is only illustrated an embodiment of the Thyroid puncture needle with negtive-pressure implement; but this utility model is not limited thereto; it will be appreciated by those skilled in the art that and can change when not departing from the protection domain described in claims of the present utility model arbitrarily and revise.
