MICRO SURGICAL KNIFE WITH SAFETY FEATURE

摘要

A surgical knife safety handle device comprises a handle body being essentially solid. A movable guard engages with the body for longitudinal movement between an extended position and a retracted position. The guard encloses a knife blade. The operation is an intuitive push/pull to extend or retract guard. The guard is formed of a clear material with a low profile that does not interfere with vision in use. The guard includes a leaf spring. The spring has a hemispherical protrusion on its underside that engages with a slot on the handle for positive engagement and an audible "click" when it seats.
