Abstract
Abstract The present invention provides a surgical device which atraumatically compresses body tissue and guides a cutting blade to transect the body tissue. Included in the surgical device is a base member equipped to hold body tissue and accurately guide a cutting blade to sever tissue at a predetermined location. A pressure applying member, preferably an arm pivotally connected to the base member, atraumatically compresses a portion of the body tissue through a compliant finger projecting from its distal end. The complaint finger is configured and dimensioned to engage the holding portion of the base member, preferably a groove formed within the base member. Parallel guiding members intersect the holding portion of the base member to guide a cutting blade substantially perpendicular to the body tissue during tissue severance.
