An existing commercialized prosthetic hand system has developed a more attractive appearance and enough driving degrees of freedom, and can meet the daily life of amputated patients, however, the existing commercialized prosthetic hand system generally lacks an effective sensory feedback function, and prosthetic hand equipment cannot be incorporated into proprioceptive mapping. On one hand, a disabled patient is easy to generate a control fatigue feeling and a psychological conflict emotion in the use process, so that the phenomenon that the use frequency of dexterous hand equipment is greatly reduced or the dexterous hand equipment is abandoned is caused; and on the other hand, the deficiency of multiple sensory feedback such as pressure sensation and position sensation also causes that the patient cannot make fine actions such as pinching, grasping and touching in real time, which becomes a key technical link urgently needing to be solved in the current artificial hand research field. The invention provides a multi-channel electrical stimulation system and stimulation method for dexterous hand touch sense and position sense feedback, which can output multi-channel portable electrical stimulation equipment with high real-time performance and wide frequency, and specially designs a multi-channel gating circuit for expanding the number of constant voltage source stimulation channels. The contradiction between the oversize circuit size and the portability requirement of an artificial hand system is solved; meanwhile, a current monitoring circuit is designed in a matched mode, and the current gathering phenomenon caused by skin impedance change or electrode falling is prevented.

The invention relates to the field of medical technology, in particular to an automatic acupoint-applied directly-pressurizing micro-needle and an application method thereof. The automatic acupoint-applied directly-pressurizing micro-needle comprises a skin feeling and contact piece and an assembly housing structure. The bottom of the skin feeling and contact piece is adhered to a micro-needle positioning piece. One side, departing from the skin feeling and contact piece, of the micro-needle positioning piece is adhered to a button positioning piece. A viscous force connecting piece is arranged between the micro-needle positioning piece and the button positioning piece. One side of connection between the viscous force connecting piece and the micro-needle positioning piece is equipped witha medical adhesive tape. The middle part of the medical adhesive tape is equipped with a micro-needle structure in an adhering manner. The middle part of one side, departing the micro-needle positioning piece, of the button positioning piece is equipped with a pressure button in an embedding manner. By pressing the pressure button on the adhesive tape, a needle point vertically pierces at one time and is closely adhered and fixed by the adhesive tape. Before the needle point pierces, the skin feeling and contact piece touching the skin excites a pressure sensation nerve receptor and inhibitsa pain sensation receptor in order to relieve pains. After the adhesive tape is attached to the skin, the adhesive tape automatically separates from the micro-needle. The operation step of imbedding aneedle during treatment is simplified.
