Abstract: Disclosed is a system to engage one or more tools. In the system, a drive shaft and collet may be assembled to engage and disengage, selectively, a plurality of tools. A guide may be used with the system to select various features of a procedure, such as depth and position.

Abstract: An adaptor assembly for coupling a cutting tool to a drill drive chuck such that driven rotation of the drive chuck is transferred to the cutting tool by the adaptor assembly. The adaptor assembly includes a rod, a collet and an enclosure. A proximal region of the rod provides an adaptor male coupling portion configured to engage a drill drive chuck. A leading of the collet provides an adaptor female coupling portion configured to engage a surgical cutting tool tang. Further, the rod and the collet form complementary engagement features for coupling to one another. The enclosure rotatably maintains the collet. Upon final assembly of the rod to the collet, rotation of the rod is transferred to the collet. During use, the adaptor assembly can facilitate coupling of a cutting tool to a powered handpiece under circumstances where the cutting tool is otherwise incompatible with the powered handpiece.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: For use in a hospital or other medical facility, provided is a powered surgical instrument. The surgical instrument can be used by doctors and the like for the dissection of bone and tissue. The surgical instrument includes a disposable drive unit and a dissection tool. The drive unit is made of a moldable or non-machined material, such as plastic, which does not have to sustain repeated use and sterilization over an extended period of time.
