A variable temperature cautery comprising a housing configured to retain a voltage source with an adaptor plug and associated heating tip assembly in operative relation to each other. A control assembly is movably attached to the housing to operatively couple a conductor disposed within the housing and the voltage source. The conductor is movable into and out of operative engagement with the adaptor plug by an actuator mechanism to selectively deliver an infinite variety of voltages to the removable heating tip assembly of the cautery. The housing or handle of the cautery is encapsulated and sterilized by placing it in a sterile bag device. A disposable tip assembly is used in conjunction with the cautery handle and covering bag and is provided with sharpened electrode leads which puncture the bag and fit into the instrument handle so that current can flow to the wire loop cutting area to provide a hot cutting tip.

Penlight

A surgical instrument comprising a housing with a motor and source of power contained in the housing. A removable sheath is placed over the housing and a cutter assembly is removably mounted to the housing so that the housing is protected from external materials and contamination. The cutter assembly has a body, a tube projecting from the body, a blade positioned in the tube and a drive transfer mechanism mounted in the cutter body, connecting the blade to the motor. The tube defines an aperture and the blade in combination with the walls defining the aperture shears tissue entering the hole. A second passage is formed in the cutter body communicating with the tube to allow pressure differentials to be exerted to the tube.
