Abstract: Disposable, bipolar electrosurgical forceps are designed to prevent the sticking of body tissue to the tips of the forceps and include a pair of electrode arms having lengths with opposite proximal and distal ends, with thin layers of biocompatible metal on the forceps arm distal ends and bipolar electrical conductors permanently secured to the forceps arm proximal ends.

Abstract: A method of detecting a brain tumor includes administering indocyanine green to a living body; exposing brain tissue in the living body; irradiating the exposed brain tissue with excitation light of indocyanine green; obtaining an image based on fluorescence of the excited indocyanine green in the brain tissue, wherein the image is obtained using an endomicroscope; and identifying portions of the brain tissue corresponding to the brain tumor based on the image.

Abstract: A method for treating a brain tumor includes providing a surgical instrument having an inner member and an outer member. The outer member has a distal region forming a cutting window. The inner member is rotatably received within the outer member, and has a cutting tip that is exposed at the window. The cutting tip and the distal region of the outer member combine to define a cutting implement. An opening is created through the patient's skull to provide access to a brain tumor target site. The cutting implement is delivered through the opening to the target site. The cutting tip is placed into contact with the tumor and operated to cut the tumor. The target site is selectively aspirated to remove cut tumor tissue.

Abstract: A torsional dissection tip and method of use comprising a longitudinal-torsional resonator having a cutting surface at a distal end with cutting teeth of a pitch optimized to the torsional or longitudinal displacement of the distal tip. The present art apparatus and method of use utilizes uniquely designed cutting surface geometries with the aforesaid pitch attributes for surgical applications. Utilization of the present art torsional dissection tip allows a surgeon to easily remove hard tissues such as bone without moving the present art instrument to any site except that which is to be dissected.

Abstract: A surgical headlight assembly having a headset structure constructed of lightweight components. The headset structure has adjustable head strap members comprising a generally circular lateral band and a top band. A removable liner is attached to the inside surface of the adjustable headset structure. A lighting assembly which is adjustable with respect to the headset and which uses an adjustable LED is also provided connected to the lateral band. A battery pack is utilized to power the LED.

Abstract: A medical instrument arrangement includes an operation microscope system (100) and a carrier unit (101) carrying the operation microscope (102). The medical instrument arrangement is at least partially covered by a drape (110). The air inside the drape (110) is removed by a suction unit. The drape (110) is fixed to a portion of the carrier unit (101) at a collar (115). By operating the suction unit at different suction rates, disturbing vibrations of the system during a surgical procedure can be minimized.

Abstract: A device for securing a previously removed cranial plate in position in a cranium to prevent relative movement between opposing bone edges includes a pin containing distal and proximal shanks having ends tapering to a relatively sharp point. One of the shanks is threaded for threadedly engaging the edge of either the cranial plate or the cranium. The shanks are arranged preferably symmetrically about a central collar which has a dimension transverse to the longitudinal axis of the shanks greater than the diameters of the shanks so that the collar forms distal and proximal opposing shoulders for limiting the insertion depth of the pin. A nut is located adjacent the collar or formed as part of the perimeter of the collar to facilitate rotation of the pin to screw in the threaded shank.

Abstract: A surgical instrument comprises an instrument head and an instrument handle. The instrument head has a proximal end, a distal end, a head static part at the proximal end, a reciprocative part generally at the proximal end, and a moveable distal part at the distal end. The reciprocative part is operatively connected to the moveable distal part so that movement of the reciprocative part between forward and rearward positions causes movement of the moveable distal part between first and second positions. The instrument handle has a handle body attachable to the head static part of the instrument head, a handle plunger configured for reciprocating relative to the handle body generally along the instrument axis, and a lever arm. The handle plunger is operatively engageable with the reciprocative part of the instrument head when the head static part is attached to the handle body.

Abstract: A remotely controlled, powered applier for attaching aneurism clips has a fixed jaw and a movable jaw at the end of an extension having two parallel rods. Longitudinal motion of a movable rod causes the jaws to open or close. The proximal ends of the rods are connected to an actuator having a radially symmetrical housing. Within the actuator, a movable rod is attached to a rotary to linear motion converter driven by a small, reversible, electric motor. Footswitches control the speed and direction of the motor and the action of the jaws. The rotary to linear converter is an internally threaded sleeve rotated by the motor and engaging a thread on the proximal end of the movable rod.
