A portable surgical wire inserting instrument comprising a housing defining a handle, a drive casing and a nose piece removably mounted to said drive casing. The housing holds a source of power electrically connected to a motor both of which are enclosed within the housing. A wire holding tube mounted in the housing is provided with a chuck at one end adapted to grab and fixedly hold an inner chuck of a sterile wire pack inserted in the wire holding tube. Beveled gears connect the motor to the wire holding tube and are adapted to rotate the wire holding tube upon energization of the motor. The sterile wire pack comprises a wire body having a plurality of flats and a cutting tip edge of smaller length than the diameter of the wire. The inner chuck is mounted on the wire body and the wire and chuck are covered with a material covering.

Wire inserter and sterile wire pack

A portable surgical wire inserting instrument comprising a housing defining a handle and a head casing. The housing handle holds a removable power pack in which is mounted a motor and a source of power electrically connected to the motor. A miter gear extends from the power pack and is connected by a drive shaft to the motor. A collet is mounted in the housing and is selectively adjusted to grip a plurality of different diameter surgical wires through the action of a knob and cam mechanism located on top of the instrument head. Rotation of the knob to one of a number of different positions establishes a number of different positions for the pivot points of thrust bars which act upon pins to draw the collet into an internally coned tube. Each position corresponds to a location of the thrust bar pivots suitable for gripping wires of different sizes. Gripping of the wire is accomplished by rotating a cam which moves the thrust bars rearward against pins which move a draw tube rearward and further draws the collet into the internally coned tube causing the jaws of the collet to squeeze in and grip the surgical wire. A miter gear on the coned tube connects with the miter gear extending from the power pack with the gears being adapted to rotate the coned tube upon energization of the motor.

Surgical wire inserter apparatus

A portable surgical wire inserting instrument comprising a housing defining a handle, a drive casing and a nose piece removably mounted to said drive casing. The housing handle holds a removable cassette in which is mounted a motor and a source of power electrically connected to the motor. A beveled gear extends from the cassette and is connected by a drive shaft to the motor. A wire housing tube mounted in the housing is provided with a chuck at one end adapted to grab and fixedly hold an inner chuck of a wire inserted in the wire holding tube. A beveled gear in the drive casing connects the beveled gear extending from the cassette to the wire holding tube with the gears being adapted to rotate the wire holding tube upon energization of the motor.

Wire inserter

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.

Vitreous cutter

A variable temperature portable cautery includes a housing configured to retain a voltage source, such as a plurality of batteries, and an electrically heated cautery tip carried by the front end of the housing in operative relation with each other. A manually operable switch is provided on the housing to allow selective energization of the cautery tip from the voltage source. A rotatably adjustable variable resistor is mounted on the rear end of the housing and is connected in circuit between the voltage source and heated tip to allow the temperature of the tip to be selectively varied. The movable contact of the switch and the wiper contact of the variable resistor are provided by the respective ends of a common conductor member extending longitudinally in the housing.
