摘要：
The implantation of cochlear implants is a way of treatment for patients with severe-to-profound sensorineural hearing loss. For minimally-invasive insertation of the implants a mechatronic tool has been developed. Miniaturized but yet automated mechanisms are needed to safely grasp and release the electrode within a small channel of less than 2 mm in diameter. A new actuation mechanism for grasping and holding the implant during insertion is presented. The system uses thermal shape memory alloy wires to open an elastic and self-closing grasping mechanism. The concept was proven in a prototypic setup and shows great potential for future development.
