Abstract
The present disclosure provides a mechanically-actuated tool for cutting a tissue graft having a hollow core and methods for use thereof. A portion of a biological structure, such as a nerve, is attached to the hollow core to form an implantable neural graft assembly. The tool has a cutter mechanism and a grasper mechanism. The grasper mechanism has one or more component(s) that open and close via an actuation mechanism, like a handle, and rotate via a controller component, like a rotatable wheel. The cutter mechanism may be a cutting tube component that harvests the tissue graft. The tool may also have an ejector mechanism to remove the tissue graft as part of the implantable neural graft assembly. Such devices and methods are particularly suitable for treating neuromas and other neural regeneration procedures.
