上肢助动器 美国科学家发明了一种瘫痪上肢用的电脉冲助动器,旨在帮助四肢瘫痪的病人通过晃动肩膀来恢复其双手功能。 这种助动器是专门为那些双手失去功能,但上身尚能轻微活动的瘫痪病人设计的。经过几年的临床试验,已由美国FDA批准推广使用。 给患者植入这种助动器时,在患者肩胛骨下的胸腔内植入一个约2英寸宽的微型计 Upper Extremity Aid American scientists invented a pulsed electric pulsator that paralyzed the upper extremities to help paralyzed patients recover their hands by shaking their shoulders. This kind of actuator is designed for those paralyzed patients who have lost their hands but are still physically active. After several years of clinical trials, has been approved by the United States FDA to promote the use. When implanting such a mover into a patient, a micrometer about 2 inches wide is implanted in the chest cavity under the scapula of the patient
