Abstract
A surgical trocar comprising a flattened oblong unit having at the front end an angled sharpened cutting edge, and at the rear end a device for removably attaching a tube for drainage or other purposes. The trocar's cutting edge produces fissure-shaped skin incisions which heal more easily than circular wounds, and the trocar's flattened shape reduces the risk of slippage and attendant damages to the patient and/or surgeon's hand from such slippage.
