Abstract
A surgical knife which provides improved multi-sided incisions and is preferably allows for a substantially cruciate, or cross-shaped incision. The surgical knife includes a handle and a multi-bladed portion located at one end of the handle. The handle is sized and configured to maximize grip and surgical manipulation thereof. The multi-bladed portion is formed from a primary blade and a secondary blade. The primary blade is configured with two exemplary primary blade members. The primary blade members are formed with sharpened edges which combined to form a sharpened distal point of the primary blade. The secondary blade is formed with sharpened edges and cooperates with the primary blade. The coupling of the primary blade and the secondary blade is such that the distal end of the secondary blade is located at a distance from the sharpened distal point of the primary blade. The combination of the primary and secondary blades form a multi-bladed portion which creates an improved, more precise and easier to control incision in a biological tissue. The surgical knife is especially useful, for example, in improved aortotomies.
