Abstract: A nerve cover for covering a nerve within a living body tissue to protect the nerve includes a base of a flat plate shape, and a pair of covers protruding upward the base to form a hole for receiving a nerve, with one end attached to the base and the other end spaced apart from the one end, wherein when the base is bent in an arch shape when viewed from a side, a spacing between the pair of covers is expanded. In addition, an apparatus for insertion of an electrode structure includes a nerve cover fixing part which fixes the nerve cover with the base being bent, and an electrode structure fixing part in which the electrode structure is mounted, and which linearly moves the mounted electrode structure in an insertion direction to insert the electrode structure into the nerve surrounded by the nerve cover.

Abstract: Provided is a tele-operated forceps-driver variable stiffness master device including a master member to generate an input displacement signal generated by pressing with a user's finger, and a slave member to operate based on the input displacement signal, measure operation information, calculate a gripping force based on the operation information, and provide the master member with at least one of a stiffness change command signal or a force feedback based on the calculated gripping force.
