神经假体

基于在体阻抗测量的视神经假体反馈系统构建

Feedback System for Artificial Electrical Prosthesis Based on In-vivo Impedance Measurement

利用这种方式形成的视觉假体称为视神经假体。

Visual prosthesis implemented by this method is called optic nerve prosthesis .

根据结果需求选择最适宜的刺激模式，获得最佳刺激结果，从而为视神经假体的研究提供一定的帮助。

According to specific requirements , the most appropriate stimulation modes can be chosen to get the best stimulation results . The study can provide some help to the research on optic nerve prosthesis . 2 .

目的探讨神经干细胞假体移植治疗脊髓损伤的疗效。

Cellular prostheses formed with neural stem cells and Sapeptide scaffold materials were transferred into the site of the spinal cord injury .

所有患者均无感染、神经损伤和假体周围骨折，无假体松动、脱位等并发症。

After surgery , there were no complications such as infection , jnjury of nerve , fractures around prosthesis , loose or dislocation of prosthesis .

结果患者术后平均随访14.6个月，均无感染、神经损伤和假体周围骨折及假体松动、脱位等并发症。

Results All cases were followed up for 14.6 months . No infection , neural injury , prosthesis adjacent fracture , prosthesis looseness or dislocation was found .

所有由中枢神经系统调节的假体生理发展经由合成肢体以一种无意识的反射行为融合在一起。

All the natural biomechanics mediated by the central nervous system emerged via the synthetic limb as an involuntary , reflexive action .

本组患者术后均无刀口感染、神经血管损伤、假体脱位、松动、折断和下肢深静脉血栓形成。

Incision infection , DVT and injury of nerve and vessels were not found . There were also no dislocation , aseptic loosening or fracture of prosthesis .

其中，用刺入式微电极阵列对视神经进行电刺激实现视觉修复的视神经视觉假体，是一种新的视觉修复手段。

Optic nerve stimulation with penetrating microelectrode array has been suggested as a possible and novel method for visual prosthesis .
