摘要：
Described herein are tissue manipulation devices having a tight bipole network. In particular, described herein are smart tools such as rongeurs configured to sense the presence of a nerve or portion of nerve. Tissue may be cut (or otherwise manipulated) by using a tool having a tight bipolar network to sense when a nerve or portion of a nerve is in the tool prior to cutting.Also described are systems for determining if a nerve is nearby an insertable tool. These systems typically include a tool with a neurostimulation electrode, an accelerometer configured to detect muscle twitch, and a feedback controller to provide feedback indicating if the tool is near a nerve. Methods of controlling insertion of a tool using feedback from such a system are also described.
