Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a visual no negative pressure hydrocone type pjncture needle of thyroid gland.
Background
Thyroid fine needle puncture has become the main examination method of thyroid cancer preoperative diagnosis, and many hospitals use no negative pressure siphon puncture needle when the thyroid is punctured at present. The present clinical thyroid non-negative pressure siphon puncture needle is a steel hollow needle with an outer diameter of 0.7mm and a length of 9cm, an insertable solid core is arranged in a needle core for sealing, and an expansion end is arranged at the tail end of the needle. When the thyroid gland is punctured, an operator holds one ultrasonic probe and the other puncture needle, and after the puncture needle punctures a tumor, the assistant assists in taking out the needle core of the puncture needle, and the puncture needle becomes a hollow needle with the length of 9 cm. The physician holds the needle and penetrates the tumor, and the fallen cells and blood are sucked into the puncture needle under the siphon action of the hollow needle. When the puncture physician thinks that enough cells are obtained, the puncture needle can be pulled out. At the moment, air is sucked by a syringe cylinder and is connected to a needle base at the tail end of the puncture needle, and cells in the puncture needle are punched on a glass sheet by using the pressure of the air and smeared or rinsed into a liquid-based preservation solution to manufacture a liquid-based slice for cytopathology diagnosis.
With current puncture needles, the problem of when the needle is withdrawn by the puncture physician is confusing. Two ways of judging needle withdrawal are commonly used: firstly, timing needle pulling: the needle withdrawing time is counted for 5-10 s or more (different due to different experience of operators), the needle withdrawing method is not scientific, and the puncture time is different according to the nature of the tumor because the nature of each tumor is different. For example, the nodule with abundant blood supply is easy to bleed during puncture, so the puncture time is short; for nodes with significant fibrosis, cells are difficult to penetrate out, and the puncture time is increased. Secondly, when the tail of the needle body sees hemorrhage, the needle is pulled out: because the needle body of the puncture needle is longer (9cm), if the tail part of the needle body can see bleeding, the bleeding time is longer, blood and cells form blood clots in the needle core, and the blood clots can cause that most of the cells which are punctured and sucked out cannot be successfully transferred to the cell coating, thereby greatly influencing the diagnosis. In clinical applications we have found that there are three problems to be improved with existing needles: firstly, the needle body is made of steel materials, is opaque, can not see blood and cells penetrating out, and is difficult to master when the needle is pulled out; secondly, the outer diameter of the puncture needle body is too thin, and the operator is uncomfortable to hold. Thirdly, the operation can not be completed by a single person and needs the assistance of an assistant. At present, a negative pressure-free thyroid siphon type puncture needle which is suitable for single-person operation and convenient to observe and hold is lacked.
