    摘要: A surgical locator circuit identifies a surgical target such as a kidney stone by disposing an emitter such as a magnetic source behind or adjacent the surgical target, and employing the circuit to identify an axis to the emitter, thus defining an axis or path to the surgical target. An array of sensors arranged in an equidistant, coplanar arrangement each senses a signal indicative of a distance to the emitter. A magneto resistor sensor generates a variable resistance is responsive to the distance to a magnetic coil emitting a magnetic field. An equal signal from each of the coplanar sensors indicates positioning on an axis passing through a point central to the sensors and orthogonal to the plane. A fixed element and signal conditioner augments and normalizes the signal received from each of the sensors to accommodate subtle differences in magneto resistive response among the plurality of sensors.

    摘要: The teachings herein relate to devices for insertion into a cavity, opening or other passageway that requires the bending of the device to conform to a curved or even tortuous shape of the path. The devices include axial support components for translating forces for moving the device forward in the path. The axial support components preferably include adjacent components capable of rocking for tilting the device in one or more directions. The device preferably includes one or more lateral support components for limiting any lateral motion of an axial support component relative to an adjacent axial support component.
