Controlling a phacoemulsification system based on real-time analysis of image data
View Patent ↗A design for dynamically adjusting parameters applied to a surgical instrument, such as an ocular surgical instrument, is presented. The method includes detecting surgical events from image data collected by a surgical microscope focused on an ocular surgical procedure, establishing a desired response for each detected surgical event, delivering the desired response to the ocular surgical instrument as a set of software instructions, and altering the surgical procedure based on the desired response received as the set of software instructions.
1. A method for performing a surgical procedure wherein performing the surgical procedure comprises controlling a surgical instrument, comprising:
detecting surgical images within a surgical environment at multiple time points during a surgical procedure;
analyzing the surgical images detected at the multiple time points during the surgical procedure to recognize and identify surgical events;
obtaining instrument readings using at least one instrument sensor at multiple time points during a surgical procedure;
assigning a desired function to at least one surgical event recognized and identified by the analyzing;
translating each desired function into a software instruction set for subsequent use in performing the surgical procedure; and
communicating sets of instructions to alter remaining portions of the surgical procedure by dynamically adjusting surgical instrument parameters based on the recognized and identified surgical events and the obtained instrument readings.
2. The method of claim 1 , wherein detecting images of surgical events comprises processing image data received from a surgical microscope.
3. The method of claim 1 , wherein detecting images of surgical events comprises processing data received from at least one instrument sensor.
4. The method of claim 2 , wherein detecting images of surgical events further comprises performing edge detection and pattern recognition techniques to determine surgical events.
5. The method of claim 1 , wherein the surgical procedure comprises an ocular surgical procedure.
6. The method of claim 5 , wherein the ocular surgical procedure comprises a phacoemulsification procedure.
7. The method of claim 3 , wherein assigning the desired function is further based on detecting pressure changes encountered in the surgical procedure.
