Abstract

A computer assisted surgery system includes a display for visual rendering of surgical data, a processor for receiving a control signal and performing operations associated with the control signal and for controlling the surgical data rendered by the display, and a wearable input device in communication with the processor. The wearable input device in one embodiment includes a mounting surface on a first side of the input device for mounting to a body portion of a user and a sensor assembly located on the side of the input device opposite the mounting surface.

Claims

1. A computer assisted surgery system comprising:

a display for visual rendering of surgical data;

a processor for receiving a control signal and performing operations associated with the control signal and for controlling the surgical data rendered by the display; and

a wearable input device in communication with the processor for receiving input from a user wearing the wearable input device, for converting the input into the control signal, and for transmitting the control signal to the processor, a memory including instructions which, when executed by the processor, causes a description of one or more steps in a surgical procedure to be rendered on the display.

2. The computer assisted surgery system of claim 1, wherein the wearable input device comprises an antenna and the control signal is transmitted to the processor using a radio frequency transmitter.

3. The computer assisted surgery system of claim 1, wherein the wearable input device comprises an optical sensor for providing an output for controlling a position of a cursor rendered on the display, the optical sensor configured to detect relative movement of a portion of the body of the user.

4. The computer assisted surgery system of claim 3, wherein;

the wearable input device comprises

a first mechanical device used to generate a first mechanical device control signal and

a second mechanical device used to generate a second mechanical device control signal; and

the processor is programmed to perform a first control function based upon the position of the cursor when the first mechanical device control signal is received and to perform a second control function based upon the position of the cursor when the second mechanical device control signal is received.

5. The computer assisted surgery system of claim 1, wherein the wearable input device is configured to be worn upon a forearm of the user.

6. The computer assisted surgery system of claim 1, wherein the wearable input device is configured to be worn upon a chest of the user.

7. A computer assisted surgery system comprising:

a display for visual rendering of surgical data;

a processor for receiving a control signal and performing operations associated with the control signal and for controlling the surgical data rendered by the display; and

a wearable input device in communication with the processor including

a mounting surface on a first side of the wearable input device for mounting to a forearm of a user, and

a sensor assembly located on a side of the wearable input device opposite the mounting surface a memory including instructions which, when executed by the processor, causes a description of one or more steps in a surgical procedure to be rendered on the display.

8. The computer assisted surgery system of claim 7, wherein the sensor assembly comprises a control pad including a plurality of mechanical switches.

9. The computer assisted surgery system of claim 7, wherein the sensor assembly comprises:

an energy source for projecting energy in an upwardly direction away from the mounting surface.

10. The computer assisted surgery system of claim 9, wherein the sensor assembly comprises:

a light source; and

a light detecting array.

11. The computer assisted surgery system of claim 10, wherein the wearable input device further comprises:

a first mechanical switch at a first end portion of the wearable input device; and

a second mechanical switch at a second end portion of the wearable input device.
