Description

Technical Field

[0002] At present, the main method of acupuncture needle insertion is manual needle insertion. Manual needle insertion is a commonly used needle insertion method in clinical practice. When holding the needle, the right hand mainly grasps the needle, and the finger force is used to make the needle tip quickly penetrate the skin. The disadvantage is that the doctor's technique is required to be high, it is not easy to control the accuracy of the depth of insertion, and it is easy to cause needle contamination, thereby contaminating the acupuncture site.

[0003] In response to the defects of manual needle insertion, there are also needle insertion devices at present, such as a single-soldier filiform needle insertion pen disclosed in CN206534866U. This patent adds a filiform needle storage unit and a filiform needle propulsion unit to solve the problems of continuous needle insertion and adjustment of needle insertion depth. The defect is that the twisting needle technique cannot be realized. The twisting technique is the most commonly used technique in acupuncture treatment. That is, after the acupuncture needle is inserted into the acupuncture point, the needle is rotated alternately to the left and right repeatedly. This technique is a key step to ensure effective acupuncture stimulation and qi.

The needle exchange motor 8 is installed on the base 7, and the power output shaft of the needle exchange motor 8 is connected to the syringe 9. The needle exchange motor 8 drives the needle placement cavity in the syringe 9 to switch and conduct with the needle outlet.
