Abstract

Claims (55)

1. A method for performing a surgical procedure, the method comprising:

analyzing a pre-operative image to generate data about an anatomical section of the patient to assist a user during surgery, wherein analyzing the pre-operative image includes:

computing a safety zone around the anatomical section;

determining if a remote controlled surgical instrument is within the safety zone, wherein one or more sensors are configured to send information to a microcontroller to assist in determining location; and

generating a notification to the user if the remote controlled surgical instrument is within the safety zone, wherein the notification is at least one of a visual, an audible notification or a haptic feedback;

receiving a real time video signal of a surgical site within the patient during a live surgery;

displaying on a user interface the generated data with the video signal;

detecting a user-initiated movement of a user input device in at least three dimensions during the live surgery, wherein detecting the user-initiated movement of the user input device includes detecting movement of the user input device that mimics a movement of a handheld surgical instrument;

translating the detected movement of the user input device into a movement signal for the remote controlled surgical instrument located at the surgical site;

comparing the real time video signal of the surgical site against the safety zone computed from the pre-operative images, wherein:

when the remote controlled surgical instrument is not in the safety zone, actuation of the user input device is permitted; and

when the remote controlled surgical instrument is in the safety zone, the notification to the user is generated;

automatically moving the remote controlled surgical instrument as mimicked based on the translated movement signal;

physically connecting a wireless remote with the remote controlled surgical instrument such that a master remote directly contacts the remote controlled surgical instrument; and

using the remote controlled surgical instrument as a handheld instrument to perform a surgical task while the remote controlled surgical instrument is physically connected to the master remote.

2. The method according to claim 1 , wherein the one or more sensors includes at least one momentum sensor used to track movement of the user input device.

3. The method according to claim 1 , wherein the remote controlled surgical instrument is a robotic instrument.

4. A method for performing a surgical procedure, the method comprising:

analyzing a pre-operative image to generate data about an anatomical section of the patient to assist a user during surgery, wherein analyzing the pre-operative image includes:

computing a safety zone around the anatomical section;

determining if a remote controlled surgical instrument is within the safety zone, wherein one or more sensors are configured to send information to a microcontroller to assist in determining location, wherein the one or more sensors includes at least one infrared sensor used to track movement of the wireless master remote, and wherein the at least one infrared sensor is disposed at a distal-most position of the wireless master remote, the at least one infrared sensor configured to facilitate physically connecting the wireless master remote with the remote controlled surgical instrument; and

generating a notification to the user if the remote controlled surgical instrument is within the safety zone, wherein the notification is at least one of a visual, an audible notification or a haptic feedback;

receiving a real time video signal of a surgical site within the patient during a live surgery;

displaying on a user interface the generated data with the video signal;

detecting a user-initiated movement of a user input device in at least three dimensions during the live surgery, wherein the user input device is a wireless master remote;

translating the detected movement of the user input device into a movement signal for the remote controlled surgical instrument located at the surgical site;

comparing the real time video signal of the surgical site against the safety zone computed from the pre-operative images, wherein:

when the remote controlled surgical instrument is not in the safety zone, actuation of the user input device is permitted; and

when the remote controlled surgical instrument is in the safety zone, the notification to the user is generated;

transferring control of the remote controlled surgical instrument from the wireless master remote to a slave remote; and

transferring control of the remote controlled surgical instrument from the slave remote to the wireless master remote by a command received from the wireless master remote.

5. The method according to claim 4 , wherein the wireless master remote is shaped similar to a handheld surgical instrument to allow the user to see simulated movements sent to the remote controlled surgical instrument.

6. A method for performing a surgical procedure, the method comprising:

analyzing a pre-operative image to generate data about an anatomical section of the patient to assist a user during surgery, wherein analyzing the pre-operative image includes computing a safety zone around the anatomical section;

receiving a real time video signal of a surgical site within the patient during a live surgery;

displaying on a user interface the generated data from the pre-operative images together with the video signal from the live surgery;

detecting a user-initiated movement of a user input device in at least three dimensions during the live surgery, wherein detecting the user-initiated movement of the user input device includes detecting movement of the user input device that mimics a movement of a handheld surgical instrument;

translating the detected movement of the user input device into a movement signal for a remote controlled surgical instrument located at the surgical site; and

comparing the real time video signal of the surgical site against the safety zone computed from the pre-operative images, wherein:

when the remote controlled surgical instrument is not in the safety zone, actuation of the user input device is permitted; and

when the remote controlled surgical instrument is in the safety zone, a notification to the user is generated, wherein the notification is at least one of a visual, an audible notification or a haptic feedback;

automatically moving the remote controlled surgical instrument as mimicked based on the translated movement signal;

physically connecting a wireless remote with the remote controlled surgical instrument such that a master remote directly contacts the remote controlled surgical instrument; and

using the remote controlled surgical instrument as a handheld instrument to perform a surgical task while the remote controlled surgical instrument is physically connected to the master remote.

7. The method according to claim 6 , further comprising sending information from one or more sensors to a microcontroller to determine when the remote controlled surgical instrument is within the safety zone.

8. The method according to claim 7 , wherein the one or more sensors includes at least one momentum sensor, and wherein the method further comprises:

tracking movement of the user input device via the one or more sensors.

9. The method according to claim 8 , wherein the one or more sensors includes at least one infrared sensor used to track movement of the wireless master remote, wherein the at least one infrared sensor is disposed at a distal-most position of the wireless master remote, and wherein the method further comprises:

using the at least one infrared sensor to physically connect the wireless master remote with the remote controlled surgical instrument.

10. The method according to claim 7 , wherein the remote controlled surgical instrument is a robotic instrument.

11. The method according to claim 6 , wherein the user input device is a wireless master remote, and wherein the method further comprises:

transferring control of the remote controlled surgical instrument from the wireless master remote to a slave remote; and
