Abstract
The utility model belongs to medical equipment, and discloses a thyroid gland puncture needle. According to the thyroid gland puncture needle, an injector is connected to the rear of a puncture needle head; a liquid collecting bottle is arranged below the injector; a liquid inlet check valve is arranged between the injector and the puncture needle head; a vent hole is formed in the side wall of the front end of the injector; and an exhaust check valve is arranged on the vent hole. When sac fluid is dense or the number of required samples is large, the sac fluid or the samples can be extracted continuously by using the injector, so that the thyroid gland puncture needle is convenient to use and operate, and has high practicality.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially is a kind of thyroid puncture needle.
Background technology
When thyroid nodule and cyst, must use puncture needle that thyroid nodule puncture acquisition Pathologic specimen is diagnosed, or capsule liquid is extracted treatment; Existing thyroid puncture needle is when extracting capsule liquid, and tail end connects syringe, because syringe can only once extract; When capsule liquid during than thickness often because negative pressure is not enough; And can not extract capsule liquid smoothly, or the sample size that extracts is not enough, brings very big inconvenience for diagnosis and disease treatment.
The utility model content
For overcoming above-mentioned technical problem, this utility model provides a kind of reasonable in design, but continuous several times extracts the thyroid puncture needle of capsule liquid.
For realizing above-mentioned technical purpose; This utility model is to adopt following technical scheme to realize: a kind of thyroid puncture needle, comprise a piercing needle, and the piercing needle rear is connected with syringe; It is characterized in that: the syringe below is provided with the liquid-collecting bottle that links to each other through catheter; Be provided with the feed liquor check valve between syringe and the piercing needle, the sidewall of syringe front end is provided with steam vent, and exhaust check valve is installed on the steam vent.
The utlity model has following beneficial effect: because the syringe below is connected with liquid-collecting bottle; The capsule liquid that extracts collects in the liquid-collecting bottle; When capsule liquid is thicker be difficult to extract or the sample of needs more for a long time; Can use syringe to extract continuously,, can prevent that capsule liquid from flowing backwards because syringe is provided with feed liquor check valve and exhaust check valve.Its reasonable in design, easy to use, swift to operate, have significant practicality.
