Miniature sensing needle for measuring mechanical parameters of scalp needle by adopting fly needle perpendicular needling technique

Abstract

The invention provides a miniature sensing needle for measuring the mechanical parameters of a scalp needle by adopting a fly needle perpendicular needling technique. The miniature sensing needle comprises a sensor pressure adjusting screw rod, an upper end cover, a lower end cover, a pressure spring, a dowel bar fixing and adjusting bolt, a dowel bar, a scalp needle fixing chuck and a scalp needle; by arranging a sensor connected with the scalp needle, when the scalp needle is operated in a fly needle perpendicular needing and lifting and inserting techniques, the scalp needle is acted by a vertical force of human body skin and tissues along with the time change, and the change causes the corresponding elastic deformation of a pressure sensing area of the sensor by the combined effect ofthe pressure adjusting screw rod fixed on the upper end of the sensor and the dowel bar fixed on the lower end of the sensor as well as the adjusting bolt and the pressure spring, so that the synchronous change of the resistivity of the scalp needle is caused; and the stress resistivity output signal is extracted by an output binding post through leads. The miniature sensing needle has the characteristics of portable structure, small size and high sensitivity and can be used for scientific research and clinical teaching; and the test analysis technology matched with the miniature sensing needle is very mature and complete.

Description

【Technical field】 [0001] The invention relates to a miniature sensing needle, in particular to a miniature sensing needle capable of quantitatively measuring the impact force of a flying needle direct pricking technique of traditional Chinese medicine scalp needle and the vertical force parameters of a lifting and insertion technique. 【Background technique】 [0002] Scalp acupuncture is a kind of physical therapy based on the meridian theory of traditional Chinese medicine. Acupuncture the corresponding projection parts of the brain function area on the scalp to adjust the physiological functions of the human body and achieve the purpose of treating diseases. In the past 40 years, scalp acupuncture has been widely used in clinical treatment of various diseases, and its curative effect is definite, so it is very popular. In fact, scalp acupuncture can have such a good curative effect, which is closely related to its unique "flying needle" direct pricking technique. This tech...

Problems solved by technology

[0003] At present, the sensing needles used in similar miniature dynamic detection at home and abroad are limited to dynamic measurement of basic acupuncture operations such as lifting and twisting in traditional acupuncture due to the defects in the selection and structural design of the internal sensor itself, and cannot Real-time detection of the biomechanical conversion signal when human skin and tissues are subjected to the vertical impact force of the needle body during the operation of the scalp needle flying needle
