A surgical apparatus and method according to which a cable assembly is connected to a handpiece and includes a sensing element, and a member adapted to move relative to the sensing element to control the operation of a motor in the handpiece.

Surgical apparatus including a hand-activated, cable assembly and method of using same

A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and a coupler disposed between the spindle and the dissection tool. The coupler includes a tool collet and an attachment locking mechanism operable to permit tool collet operation and telescoping movement of an attachment tube with respect to the dissection tool. A method is also provided for convenient coupling of the dissection tool and adjustment of the attachment tube length.

Surgical instrument with telescoping attachment

A system for use in a surgical procedure comprising a pneumatic instrument having an inlet and an outlet, a tank fluidly coupled to the inlet of the pneumatic instrument, wherein the tank provides pressurized helium gas to power the pneumatic instrument, and a compressor fluidly coupled to the outlet of the pneumatic instrument. The compressor receives the helium gas exhausted from the pneumatic instrument and compresses the exhausted helium gas to supply the tank with pressurized helium gas.

Recycled helium gas surgical instrument

A surgical attachment instrument and method according to which a housing is adapted to be coupled to a motor. A tubular member is coupled to the housing so that an end of the tubular member extends from the housing at a predetermined distance. The predetermined distance may be selectively adjusted by a repeatable increment.

Surgical attachment instrument and method

The present invention provides improved coupling arrangements for medical instruments. In one example, a coupling system for a medical dissection tool includes: an internal passage adapted for receiving a portion of a medical dissection tool; and at least one locking member movable through a first angled path into a locked position to prevent the medical dissection tool from moving along a longitudinal axis of the internal passage.

Coupling system for surgical instrument

A surgical apparatus and method according to which an assembly is connected to a handpiece and includes a sensing element and a member adapted to move relative to the sensing element to control the operation of a motor in the handpiece.

A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and an coupler disposed between the spindle and the dissection tool. The coupler includes a tool collet and an attachment locking mechanism operable to permit tool collet operation and telescoping movement of an attachment tube with respect to the dissection tool. A method is also provided for convenient coupling of the dissection tool and adjustment of the attachment tube length.

In one embodiment, there is disclosed a surgical instrument for the dissection of bone or other tissue, the surgical instrument including a tool having a shaft with a dissection area disposed adjacent a distal end and a coupling area disposed adjacent a proximal end; a coupling assembly configured for coupling to a power output of a motor to said coupling area of said tool; and an angled attachment tube positionable along at least a portion of said shaft and substantially supporting a portion of said shaft disposed adjacent said dissection area.

Surgical instrument with angled attachment

A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and a male member carried by the spindle. The spindle includes a cavity. The dissection tool is releasably received in the cavity. The dissection tool extends along an axis and includes a first end and a second end with the first end having a cutting element and a second end having a generally cylindrical cross-section and a centrally located aperture partially extending along the axis. The male member is carried by the spindle and extends into the aperture of the dissection tool.

Surgical instrument with rotary cutting member and quick release coupling arrangement

A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and a male member carried by the spindle. The spindle includes a cavity. The dissection tool is releasably received in the cavity. The dissection tool extends along an axis and includes a first end and a second end with the first end having a cutting element and a second end having a generally cylindrical cross-section and a centrally located aperture partially extending along the axis. The male member is carried by the spindle and extends into the aperture of the dissection tool. The cavity may define a drive portion and a tool receiving aperture. One or more alignment projections may extend from the drive portion into the tool receiving aperture.

A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and an adaptor disposed between the spindle and the dissection tool. The spindle includes a cavity and a male member projecting into the cavity. The adaptor includes a drive shaft that extends along an axis and includes a first end having a generally cylindrical cross-section and a centrally located aperture partially extending along the axis. The male member is carried by the spindle and extends into the aperture of the dissection tool. The cavity may define a drive portion and a tool receiving aperture. One or more alignment projections may extend from the drive portion into the tool receiving aperture.

A surgical instrument is provided for cutting bone and other tissue. The surgical instrument includes a motor assembly, a collet, a locking nut, and an attachment. The motor assembly includes a cavity having a groove on an inner surface that corresponds to a groove on an outer surface of the collet. The corresponding grooves form an aperture when the collet is inserted into the cavity. The insertion of a pin into the aperture prevents rotation of the collet relative to the cavity. The locking nut is placed over the collet and fastened to the motor assembly to secure the collet to the motor assembly. The attachment is fastened to the collet by placing protuberances on the attachment into corresponding apertures on the collet. The consistent alignment provided by the locking and indexing system enables the motor assembly and attachment to receive alignment markings before the surgical instrument is assembled.
