Stereotactic drive system
First Claim
1. A drive system, comprising:
- a base unit including first and second spools to spool, respectively, first and second wires; and
an assembly extending in a longitudinal direction and coupled to the base unit by the first and second wires, the assembly including a mount coupled to the assembly, and the mount including a rotatable portion and first and second wire supports that support, respectively, the first and second wires, wherein;
the rotatable portion is rotatable about an axis of rotation that extends in the longitudinal direction, and is structured to hold and rotate an elongated member about the axis of rotation,the first wire support is coupled to the mount and the assembly such that a movement of the first wire along the first wire support causes the mount to move along the assembly in the longitudinal direction, andthe second wire support is coupled to the mount and the rotatable portion such that a movement of the second wire along the second wire support causes the rotatable portion to rotate about the axis of rotation of the rotatable portion, and wherein;
the base unit includes first and second spool shafts for each of the first and second spools, such that rotational movements of the first and second spools cause rotations of the first and second spool shafts;
opposing ends of the first wire are connected to the first and second spools shafts for the first spool, such that the rotational movement of the first spool causes, concurrently, both the first and second spool shafts for the first spool to rotate, causing the first and second spool shafts for the first spool to respectively wind and unwind the first wire; and
opposing ends of the second wire are connected to the first and second spools shafts for the second spool, such that the rotational movement of the second spool causes, concurrently, both the first and second spool shafts for the second spool to rotate, causing the first and second spool shafts for the second spool to respectively wind and unwind the second wire.

Abstract
A drive system for controlling movement of an elongate member includes a base unit having a first rotatable knob and a second rotatable knob, a follower assembly including a follower slidably coupled to a guide rail, a longitudinal movement wire, and a rotational movement wire. The follower includes a longitudinal movement pulley, a rotational movement pulley, and an alignment element structured to receive an elongate member such that the elongate member is attachable thereto. The longitudinal movement wire operably couples the first rotatable knob to the longitudinal movement pulley such that rotation of the first knob drives the follower in a longitudinal direction along the guide rail. The rotational movement wire operably couples the second rotatable knob to the rotational movement pulley such that rotation of the second knob rotates the alignment element and attached elongate member.

21. A method for a drive system,
the drive system comprising: -
a base unit including first and second spools to spool, respectively, first and second wires, and first and second spool shafts for each of the first and second spools, such that rotational movements of the first and second spools cause rotations of the first and second spool shafts, wherein opposing ends of the first wire are connected to the first and second spools shafts for the first spool, such that the rotational movement of the first spool causes, concurrently, both the first and second spool shafts for the first spool to rotate, causing the first and second spool shafts for the first spool to respectively wind and unwind the first wire; and
opposing ends of the second wire are connected to the first and second spools shafts for the second spool, such that the rotational movement of the second spool causes, concurrently, both the first and second spool shafts for the second spool to rotate, causing the first and second spool shafts for the second spool to respectively wind and unwind the second wire; andan assembly extending in a longitudinal direction and coupled to the base unit by the first and second wires, the assembly including a mount coupled to the assembly, and the mount including a rotatable portion and first and second wire supports that support, respectively, the first and second wires, wherein; the rotatable portion is rotatable about an axis of rotation that extends in the longitudinal direction, and is structured to hold and rotate an elongated member about the axis of rotation, the first wire support is coupled to the mount and the assembly such that a movement of the first wire along the first wire support causes the mount to move along the assembly in the longitudinal direction, and the second wire support is coupled to the mount and the rotatable portion such that a movement of the second wire along the second wire support causes the rotatable portion to rotate about the axis of rotation of the rotatable portion; and the method comprising; rotating the first spool to drive the mount in one of opposing forward and backward directions coinciding with the longitudinal direction based on a direction of the rotating of the first spool; and rotating the second spool to rotate the rotatable portion in one of opposing clockwise and counter-clockwise directions about the rotational axis of the rotatable portion based on a direction of the rotating of the second spool. - View Dependent Claims (22, 23)
