Abstract

Lifting and thrusting constitute an important manipulation method in traditional Chinese acupuncture. Lifting and thrusting enables the implementation of various features, such as reinforcement and reduction, which enhance acupuncture effectiveness. Laser acupuncture stimulates acupoints through laser light, which is a noninvasive treatment, but can still achieve effects similar to those obtained from traditional acupuncture. Lifting and thrusting can be achieved by moving the laser focal point back and forth, thus concentrating the energy, as does the tip of the acupuncture needle when it is moved upward and downward in the acupoint. This article presents a novel optical design of a laser acupuncture device, in which a focus-tunable lens is used to move the position of the focused light in order to achieve the lifting and thrusting mechanism through programmable changes to the control current of the focus-tunable lens. The device employs an infrared laser with a wavelength of 808 nm and a maximum power of 150 mW. The focus-tunable lens used in this study had a diopter of 10 to +5. The results revealed that by controlling the lens diopter, the focused light can be moved from 4.5 to 9.5 cm. Therefore, the range of the lift and thrust for the laser acupuncture device was 5 cm. The area of the focal point was approximately 6×103mm2, which is comparable to that of the commonly used traditional acupuncture needle tip. Because the components are immobile, no additional space is required for the moving lens. Therefore, the size of the laser acupuncture head can be minimized, and the effectiveness of focus tuning can be improved.
