Artificial facial nerve prosthesis with facial nerve substituting function

Abstract

The invention relates to an artificial facial neural prostheses to replace the function of facial nerves, which pertains to the biomedical engineering field, wherein, a signal collection module collects the electromyographic signals of facial muscles at the healthy side of the face, the signals are sent to a control and treatment module to complete the analysis and treatment of the signals, the conversion treatment of the stimulation pulse is realized, the energy is supplied by an energy supply module, the stimulation pulse is sent to a multi-line pulse stimulation module, and the electric stimulation on the muscles of the affected side is realized by a micro-stimulation electrode so as to cause the contraction of facial muscles; a feedback module collects the electromyographic signals of the affected side of the face, the signals are sent back to the control and treatment module to realize the regulation of the stimulation pulse, a wireless transmitting and receiving module transmits the information in vivo to the outside and receives the control signals for in vitro input, so as to realize the calibration and regulation of the artificial prostheses with the function of facial nerves. The invention can generate the corresponding symmetrical movements of the affected facial muscles according to the received stimulation of the normal electrical signals of the opposite side, so as to maintain the symmetry and consistency of the facial expression muscles; furthermore, the invention can stimulate the muscles for the prevention of atrophy and promote the growth of the transected nerves.

Description

technical field [0001] The invention relates to an artificial prosthesis in the field of biomedical engineering, in particular to an artificial facial nerve prosthesis for replacing the function of the facial nerve. Background technique [0002] Peripheral facial palsy is the clinical facial nerve dysfunction often caused by disconnection or compression of the upper nerve after it exits the brainstem. The lesions of the facial nerve can be caused by various tumor operations such as infectious diseases, trauma, ear-derived diseases, facial nerve, and auditory nerve, and some are unavoidable and unhealed for life. Due to the non-renewable and non-proliferative properties of nerve cells, there is still no effective treatment for facial nerve damage clinically. At present, the main clinical treatments include facial nerve decompression surgery and facial nerve transplantation. In addition, there are some non-surgical treatments such as electrical stimulation therapy and traditi...

Problems solved by technology

[0003] After searching the existing technical literature, it was found that Kun Dan et al. wrote an article "Development of Handheld Facial Nerve Muscle Stimulation Therapeutic Instrument" in "Medical Equipment Information" 19 (3) (2003) pp14-16. Facial nerve growth can be promoted, but in the above experiments, the stimulation is not continuous, and long-term stimulation only refers to the treatment of 6 hours a day for 6 months, and even a convenient stimulator will affect the patient's activities during treatment. certain restrictions
