A scalpel with a retractable blade comprising a handle having a proximal section grasped by the surgeon and a distal section, and a blade holder slidable in a channel defined in the distal section of the handle. The distal section has a hinged flap to provide access to the blade for removal and replacement of the blade when in the retracted position, and can accommodate disposable blades having a variety of sizes and shapes. The scalpel has an ergonomically shaped button mounted on the blade holder providing fingertip control over retraction and extension of the blade.

[ I claim:] [1.] A scalpel with a retractable blade comprising:a) a handle having a proximal section and a distal section, the proximal section having a proximal channel defined therein and the distal section having a distal channel defined therein, and a distal end having a slot defined therein, the distal section of said handle having substantially the shape of a parallelepiped, including a top surface, a bottom surface, a lateral surface, and a second lateral surface;b) a blade holder slidably disposed within said distal channel, said blade holder having a body, the body having a top surface and including mounting means for mounting a disposable scalpel blade on said blade holder;c) sliding means for sliding said blade holder in the distal channel of said handle;d) biasing means for retaining the blade holder in a retracted position whereby the scalpel blade is disposed entirely within said distal channel;e) a locking means for retaining the blade holder in a cutting position whereby the scalpel blade is extended through the slot in the distal end of said handle and locked in position; andf) access means for access to the scalpel blade when the blade holder is in the retracted position whereby the blade may be removed and replaced, said access means including a flap door pivotally hinged to the lateral surface of the distal section of said handle, said door having an open position and a closed position, said door and said second lateral surface being convex downwards and defining a slot in the bottom surface of said distal section.
