Abstract
A surgical device is provided includes a hand-held portion with a working portion movably coupled to the hand-held portion for driving a tool. Actuators are provided for moving the working portion with each of the actuators having a travel range. An indicator notices a user when at least one of actuators is: (i) within the travel range; (ii) approaching a travel limit of the travel range; or (iii) outside the travel range. A surgical system is also provided inclusive the surgical device and a computing system configured to activate the indicator.
Claims22
A surgical system for inserting a pin in a bone coincident with a virtual plane having a predetermined location relative to a bone, comprising:
- a robotic surgical device for aligning or maintaining alignment of an axis of the pin coincident with the virtual plane in response to control signals;
- a computer configured to receive inputs that comprise the predetermined location of the virtual plane, and a location of at least one of the bone and the robotic surgical device, wherein the computer comprises a processor configured to generate the control signals using the inputs;
- and
- a cutting guide configured to couple to one or more pins already inserted in the bone, wherein the cutting guide comprises an opening configured to receive a bone removal tool.
A surgical system for inserting a pin in a bone coincident with a virtual plane having a predetermined location relative to a bone, comprising:
- a hand-held device, comprising
- a hand-held portion;
- a working portion movably connected to the hand-held portion and comprising a motor for driving the pin;
- and
- an actuator system for moving the working portion relative to the hand-held portion in response to control signals to align or maintain alignment of an axis of the pin coincident with the virtual plane;
- a computing system configured to receive inputs that comprise the predetermined location of the virtual plane, and a location of at least one of the bone and the hand-held device, wherein the computing system comprises one or more processors configured to generate the control signals using the inputs;
- a tracking system for determining the location of the at least one of the bone and the hand-held device;
- and
- a cutting guide configured to couple to one or more pins already inserted in the bone, wherein the cutting guide comprises an opening configured to receive a bone removal tool.
