  • Patent number: 11357535
    Abstract: A scalpel has a handle (1) and a blade carrier (2) movable within a longitudinally extending cavity therein between an operative position in which a blade (5) on the blade carrier is exposed for use and an inoperative retracted position. A manually operable slider (4) moves the blade carrier (2) that has a catch face (21) directed rearwards in the operative position. The catch face partially aligns with a stop face (22) provided on the handle (1) in the normal operative position of the blade carrier such that force exerted on a blade carried by the blade carrier in the direction of the length of the handle causes engagement of the catch face with the stop face to arrest movement of the blade carrier into the cavity. Transverse biasing of the blade carrier (2) is overcome by pressure exerted on the slider (4) to retract the blade carrier (2) into the handle with the catch face (21) passing the stop face (22).

  • Patent number: 11000309
    Abstract: A safety scalpel having a retractable protective guard for covering a blade of the scalpel when the scalpel is not in use is provided. The protective guard limits inadvertent contact with the scalpel blade which may reduce the likelihood of accidental cuts or damage to the blade.

  • Patent number: 10492768
    Abstract: A handheld biopsy device is provided which includes an elongate base having a slider movable relative thereto between a stowed condition and at least one operative condition. An elongate blade which is resiliently flexible in its length is secured between the base and the slider such that with the slider in the stowed condition the blade extends generally parallel to the base, and with the slider in the at least one operative condition the blade flexes away from the base into a bowed shape.

  • Patent number: 8931181
    Abstract: A scalpel blade accessory and cartridge are provided wherein a tubular guard is slidable over the scalpel blade carrier between a retracted position in which the blade carrier is positioned to expose any scalpel blade associated with it for use and an extended position in which the guard covers the blade carrier and any blade thereon. The scalpel blade has a mounting slot for attachment to a lug on a standard scalpel handle for use. The blade carrier has a bridge spanning an alignment face so as to provide space for a scalpel blade between the alignment face and bridge. A blade catch cooperates with a rear end of the mounting slot to hold a relevant scalpel blade captive. The blade catch is disengagable by assembling it onto a standard handle, in use.
