摘要： A surgical drilling instrument with a Curved Burr Attachment having an adapter removably coupled to a drill motor and a burr attachment coupled to said adapter. The burr attachment includes a tube with a wire shaft supported therein and a coil wire surrounding said wire shaft and having each of the coils touch the outer periphery surface of the wire shaft and the inner peripheral surface of said tube to enhance cooling of said outer periphery of said tube from the heat generated by said wire shaft and attenuate vibrations while allowing said burr attachment to be bent without kinking. The burr attachment includes a proximal end support and a distal end support formed on the end of said burr attachment wherein the wire shaft is affixed to said proximal end support and rotates relative to said distal end support and includes detents formed on each of the supports for engaging balls in said adapter so as to be operatively connected thereto when the burr attachment is aligned in said adapter to couple the burr attachment to said adapter for rotary motion of said wire shaft and locating the cutter of said burr attachment to a precise location relative to the end of the adapter. The burr attachment being disposable and the adapter being re-usable.

摘要： A high speed surgical instrument is designed with a clutch that automatically locks a cutter which is easily assembled and disassembled without moving parts. The clutch includes a pin and U-shaped pin that compliments a configured groove section at the proximal end of a cutter that fits into a clutch mechanism in the drill or attachment. The cutter includes axially spaced and opposed grooves judiciously located and a flat end portion that allows easy ingress and egress for locking into the clutch mechanism. A square or multi-sided bore configuration of a journal type bearing made from a high temperature resistance polymer material allows the drill to operate at high speeds with a reduction in the diameter of the distal end of the cutter support.

摘要： The rotary motion created by a motor is transmitted from the drive shaft of the motor to the driven shaft through a pair of diametrically opposed balls fitted into a coupling mechanism attached to the drive shaft and through a pin fitted into holes formed in the opposed balls and through the driven shaft disposed between the opposed balls for eliminating vibration and noise. The thrust loads imposed in the structure supporting the motor is directed to bypass the motor through a bearing supporting the driven shaft through its housing and into the outer housing surrounding the motor. The motor is encased in a cartridge disposed in a central cavity of the outer housing and the cartridge is not rigidly attached to the outer housing so that the thrust loads bypass the motor.

摘要： A burr attachment removably attached to an adapter rotary driven by a motor that includes a tube with a wire shaft supported therein and a wire coil (no spring rate) serving as a journal bearing rotary supporting the wire shaft and having each of the coils randomly touch the outer periphery surface of the wire shaft and the inner peripheral surface of the tube to enhance cooling and attenuate vibrations while allowing the burr attachment to be bent without kinking. The burr attachment includes a proximal end support and a distal end support that removably attaches to the adapter. The wire shaft is affixed to the proximal end support and rotates relative to the distal end support operatively connected to the adapter. Only the burr attached is removable and disposable while the adapter and motor are re-usable.

摘要： A journal bearing for a high speed surgical drill and/or attachment for rotatably supporting a cutter is made from a polymer of polyimide resin and graphite material and is designed to have a polygon configured bore where there are two point contact of the mating surfaces of the bore walls and cutter's shaft and preferably the bore is square shaped in cross section. This bearing results in a decrease in the envelope size of the support tube and hence, the overall diameter of the surgical instrument at the distal end enhances the line of vision of the cutter to the surgeon when the surgeon is performing surgical procedures. The entrance ends of the intermediate bearings are countersunk to define a ramp to ease the egress of the tool bit shaft for entering the tube of the drill motor or drill attachment during the assembly thereof.

摘要： A cutter for a surgical drill and/or attachment includes a configured groove section at the proximal end that fits into a clutch mechanism in the drill or attachment. The distal end portion is flattened at above the center line and extends axially a short distance and defines a shoulder with the outer circumference of the shaft of the cutter. A pair of diametrically grooves disposed downstream of the shoulder toward the distal end are formed on the upper and lower portion of the shaft and are oriented in a horizontal plane passing through the center of the flat portion and include in each of the grooves a pair of predetermined angular grooves displaced from the upper circumferential surface with the apex of the angle being in the horizontal plane and another groove adjacent to and upstream of the shoulder toward the proximate end with a predetermined angle with the apex passing through the horizontal plane.

摘要： A burr attachment designed for use with a Curved Burr Attachment or other chuck attachments that includes a tube with a wire shaft supported therein and a coil spring surrounding said wire shaft and having each of the coils touch the outer periphery surface of the wire shaft and the inner peripheral surface of said tube to enhance cooling of said outer periphery of said tube from the heat generated by said wire shaft and attenuate vibrations while allowing said burr attachment to be bent without kinking. The burr attachment includes a proximal end support and a distal end support formed on the end of said burr attachment wherein the wire shaft is affixed to said proximal end support and rotates relative to said distal end support and includes detents formed on each of the supports for engaging balls in said adapter so as to be operatively connected thereto when the burr attachment is aligned in said adapter to couple the burr attachment to said Curved Burr Attachment or other chuck attachments for rotary motion of said wire shaft and locating the cutter of said burr attachment to a precise location relative to the end of the Curved Burr Attachment or other chuck attachments. A dimple and annular groove are formed in the proximal end support and distal end support respectively to avoid the cutter from being inadvertently dislodged. A significant purpose of the burr attachment is that it is disposable while the chuck or the adapter of the Curved Burr Attachment is re-usable.
