  • Micro surgical knife with safety feature
    Patent number: 8875405
    Abstract: 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.

  • MICRO SURGICAL KNIFE WITH SAFETY FEATURE
    Publication number: 20110251631
    Abstract: A surgical knife safety handle device comprises a handle body being essentially solid and has at least one formation on the outside of the body. There is a knife holder at the distal end of the handle body. A movable guard engages with the formation for longitudinal movement between an extended position and a retracted position with respect to the handle body. The guard has a proximal end and a distal end for at least partially enclosing a knife blade attachable to the knife holder, and the guard is slidably mounted with the formation. The device permits for one handed operation. The mode of operation is apparent and 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, and thus reduces shadowing in the operative field.
