Patent ID: 6929603

Claim:
A variable view arthroscope having more than one viewing position in a range between a first viewing position and a second viewing position, comprising: a housing having an input end and a control end, the housing having a longitudinal axis; an input assembly disposed in the input end of the housing, a position of the input assembly defining a viewing position of the arthroscope, the position being adjustable; a push rod mechanically connected to the input assembly to adjust the position of the input assembly; a first magnet assembly disposed outside the housing, the first magnet assembly being rotatable around a first internal axis orthogonal to the longitudinal axis; and a second magnet assembly disposed inside the housing, the second magnet assembly being rotatable around a second internal axis orthogonal to the longitudinal axis, said second magnet being mechanically coupled to the push rod, wherein rotation of the first magnet assembly magnetically induces rotation of the second magnet assembly, and wherein rotation of the second magnet assembly creates a linear motion of the push rod along the axis.
