The present invention relates to a powered surgical tool that selectively provides rotational oscillations to a tool head (effector) to effect tissue modification during a surgical procedure. The present invention also relates to cutting tools and tissue modification tools that operate to modify tissue when rotated in either or both directions about the longitudinal axis of the tool. The present surgical tool and cutting tools are effective to modify selective tissues while selectively preventing the modification of other tissues. For example, hard tissue, like bone, may be modified while soft tissue is not modified, or soft tissue may be modified without modification to hard tissue.

Powered surgical tool with transmission

An oscillating drive mechanism for a surgical tool includes a motor having a rotor, a crank assembly hub, a link secured to the crank assembly hub, a pivot shaft, a shuttle including an arcuate rack gear secured to the link so that rotation of the crank assembly hub provides reciprocating rotary motion to the arcuate rack gear about the pivot shaft. A gear is meshed with the arcuate rack gear and is secured to an output shaft, whereby rotational motion of the motor induces rotary oscillating motion to the output shaft.

A bone, cartilage, and disk removal tool assembly is provided with a motor mounted in a housing. A spindle is mounted for rotation to the housing. A rack-and-pinion mechanism is operably driven by the motor and connected to the spindle to oscillate the spindle for providing a rotary oscillating cutting operation. According to at least another embodiment, a plurality of cams is supported in the housing and driven for rotation by the motor. A plurality of followers is mounted for rotation to the housing, in engagement with the plurality of cams so that one rotation of the plurality of cams oscillates the plurality of followers more than once while preventing over-rotation of the plurality of followers. A peak angular acceleration of the spindle is less than nine million radians per second squared.

A displaceable speaker assembly for a vehicle includes a housing, a speaker array rotatably coupled to the housing and including a plurality of electro-acoustic transducers (e.g., twiddlers), a drive unit coupled to the housing, and a lever assembly coupling the drive unit to the speaker array. The drive unit is operable to drive motion of the lever assembly, which, in turn, drives rotation of the speaker array relative to the housing.

Displaceable speaker array and related assemblies

A sliding vehicle window assembly which includes at least one, and preferably a pair, of window panels spaced from each other to define a window opening and interconnected by upper and lower frame members or tracks, bonded to the interior surface of the pair of window panels. The upper and lower frame members are also spaced vertically apart from each other. At least one, and preferably two, arcuate channels are defined in each of the inwardly facing walls of the two frame members--the two channels arranged generally in tandem or end-to-end alignment. The pair of channels in each frame member are configured to receive a window panel, opposite ends of which retain cam or channel followers received by the channels. A latch handle interconnects one end of each cam follower and includes a cam projection also received in the channel and when rotated in one end of the channels, moves the sliding window generally perpendicularly with respect to the window opening when the window is located over the window opening. The sliding window is sealed against the window opening by a seal fixed to the interior surface of the fixed window panels carried in a seal carrier which spans the upper and lower portions of the window opening. The advantages include a sliding vehicle window assembly which is substantially flush with the exterior of the vehicle. There are no components which extend beyond the exterior surface of the fixed panels. Additionally, all of the components may be injection molded from lightweight, rigid materials, resulting in less expense. Moreover, the window assembly design is easy to assemble resulting in less man hours per unit and, as a result, less cost. The window assembly is easily adapted to any one of a number of different gasketing techniques used to retain the vehicle window assembly in the vehicle window opening.

The advantages resulting from the various forms of the invention include a sliding vehicle window assembly which is substantially flush with the exterior of the vehicle. There are no components which extend beyond the exterior surface of the fixed panels.
