Abstract
An articulating drill system is provided that includes a hand-held portion and a drill portion. At least two actuators are provided for controlling at least two axes of the drill portion. In some embodiments, a tool is provided with the drill portion and adapted to interact with patient tissue. The drill portion can be modified to include at least two rigid objects in communication with the actuators and attached to the drill portion. The system can be used to make any linear cut within a deviation of ±1.0 mm and ±1.0°, or better in patient tissue.
Claims20
A surgical device, comprising
- a hand-held portion having a first longitudinal axis;
- a saw portion coupled to the hand-held portion and configured to be coupled to a saw blade having a second longitudinal axis;
- an assembly of components configured to control the position and orientation of the saw portion relative to the hand-held portion, wherein the assembly of components comprises:
- a plurality of lead screws;
- and
- a plurality of motors coupled to one or more controllers, wherein each motor is coupled to one of the plurality of lead screws and configured to rotate that lead screw in response to control signals received from the one or more controllers, wherein rotation of the plurality of lead screws provides motion between the saw portion and the hand-held portion in at least two degrees-of-freedom to maintain the saw blade in a pre-planned plane in response to movement of the hand-held portion;
- and
- wherein the at least two degrees-of-freedom comprises:
- (i) rotation between the saw portion and the hand-held portion;
- and (ii) translation between the saw portion and the hand-held portion in a direction of the first longitudinal axis of the hand-held portion without translation in a direction of the second longitudinal axis of the saw blade coupled to the saw portion.
A surgical system, comprising:
- one or more controllers for sending control signals;
- and
- a surgical device, comprising:
- a hand-held portion having a first longitudinal axis;
- a saw portion coupled to the hand-held portion and configured to be coupled to a saw blade having a second longitudinal axis;
- an assembly of components configured to control the position and orientation of the saw portion relative to the hand-held portion, wherein the assembly of components comprises:
- a plurality of lead screws;
- and
- a plurality of motors coupled to one or more controllers, wherein each motor is coupled to one of the plurality of lead screws and configured to rotate that lead screw in response to control signals received from the one or more controllers, wherein rotation of the plurality of lead screws provides motion between the saw portion and the hand-held portion in at least two degrees-of-freedom to maintain the saw blade in a pre-planned plane in response to movement of the hand-held portion;
- and
- wherein the at least two degrees-of-freedom comprises:
- (i) rotation between the saw portion and the hand-held portion;
- and (ii) translation between the saw portion and the hand-held portion in a direction of the first longitudinal axis of the hand-held portion without translation in a direction of the second longitudinal axis of the saw blade coupled to the saw portion.
