Description

Technical Field

[0001] The utility model belongs to the technical field of thyroid gland, in particular to a visual quantitative automatic aspiration thyroid gland puncture device. Background Art

[0002] Fine needle aspiration of the thyroid has become the primary method for preoperative diagnosis of thyroid cancer. Currently, many hospitals use a non-negative pressure siphon puncture needle for thyroid puncture. However, the traditional puncture device has a relatively simple structure and therefore has the following shortcomings during use:

[0003] 1. Many puncture devices rely on medical staff to manually pull the piston for extraction, which can easily lead to deviations in the extraction volume and makes it difficult to extract quantitatively.

[0004] 2. After the puncture needle is inserted into the human body, some human tissue is likely to remain inside the puncture needle, which may easily cause the puncture needle to be blocked.

[0005] To this end, we proposed a visual quantitative automatic aspiration thyroid puncture device. Utility Model Content

[0017] In a possible design, a limiting ring is integrally formed on the inner wall of the connecting pipe.

[0018] In a possible design, two symmetrically arranged anti-slip sleeves are bonded to the outer wall of the cylinder.

[0019] In this application, when in use, first use the control panel to set the extraction volume, then insert the puncture needle into the human body from the appropriate part, and then rotate the adjustment ring, the adjustment ring drives the sealing ring to slide, the sealing ring drives the slider to move, and the slider drives the guide needle to move, so that the bottom end of the guide needle extends out of the puncture needle, and then the fluid channel extends out, and then start the motor, the motor drives the screw to rotate and then drives the piston to move, and then extraction is carried out. The motor can complete the quantitative extraction after running for the specified time according to the setting.
