摘要

A novel laser-acupuncture system was developed that can be used to implement the manipulation methods of traditional acupuncture, such as lifting and thrusting. A 780 nm laser diode with a maximum power of 90 mW was used as the light source. The focus point of the laser beam was adjustable by changing the position of the lens, facilitating the implementation of the lifting and thrusting methods of traditional Chinese medicine and achieving various stimulation depths at the acupuncture point. The images for the light spots from the outlet of the emulated laser acupuncture were captured at various distances and their sizes were calculated. The result showed that the diameter of the focused light spot (i.e., at the focus point) was 0.11 mm, which is close to the diameter of commonly used needles (with diameters of approximately 0.22 mm). The area of the light spot 1 cm from the focus point was approximately 50 times larger, indicating that the unit power might be 1/50 of the power of the focus point. To study the effect of emulated laser acupuncture on human meridians, after stimulating the Shenmen point (HT7) of five subjects and obtaining their Ryodoraku values of the heart meridian and the small-intestine meridian, a paired t test showed that the laser stimulation incorporating lifting and thrusting was significantly higher than the laser stimulation without lifting and thrusting (p < 0.05). The result is consistent with traditional acupuncture in that acupuncture incorporating lift and thrust is more effective than that without lift and thrust.
