Abstract
The present invention provides a system for managing occlusions during phacoemulsification surgery. More specifically, the present invention provides a user of a surgical console an alert when a partial or full occlusion of a surgical tool causes the vacuum pressure to become greater than a predetermined pressure threshold setting and automatically reduces the vacuum pressure when the predetermined pressure threshold setting is exceeded.
Claims42
A method for managing occlusions during phacoemulsification surgery, the method comprising:
- providing, by a surgical console having at least one system bus communicatively connected to at least one computing processor capable of accessing at least one computing memory associated with the at least one computing processor, a vacuum system capable of providing vacuum pressure between a minimum pressure and a maximum pressure;
- receiving a first pressure threshold setting and a second pressure threshold setting, wherein the first pressure threshold setting is greater than the minimum pressure and less than the second pressure threshold setting and wherein the second pressure threshold setting is less than the maximum pressure;
- providing a user of the surgical console an alert in response to the vacuum pressure being greater than the first pressure threshold setting;
- and
- automatically reducing the vacuum pressure in response to the second pressure threshold setting being exceeded.
A system for managing occlusions during phacoemulsification surgery, the system comprising:
- a surgical console having at least one system bus communicatively connected to at least one computing processor capable of accessing at least one computing memory associated with the at least one computing processor;
- at least one vacuum source associated with the surgical console for providing a vacuum pressure between a minimum pressure and a maximum pressure;
- a phacoemulsification surgical handpiece having at the distal end at least one surgical tool and having near the proximate end a receiver for receiving an aspiration line from the surgical console;
- and
- an input means for receiving a first pressure threshold setting and a second pressure threshold setting, wherein the first pressure threshold setting is greater than the minimum pressure and less than the second pressure threshold setting and wherein the second pressure threshold setting is less than the maximum pressure.

- a surgical console having at least one system bus communicatively connected to at least one computing processor capable of accessing at least one computing memory associated with the at least one computing processor;
- at least one vacuum source associated with the surgical console for providing a vacuum pressure between a minimum pressure and a maximum pressure;
- a phacoemulsification surgical handpiece having at the distal end at least one surgical tool and having near the proximate end a receiver for receiving an aspiration line from the surgical console;
- and
- an input means for receiving a plurality of pressure threshold settings, wherein ones of the plurality of pressure threshold settings are greater than the minimum pressure and less than the maximum pressure.
A method for managing occlusions during phacoemulsification surgery, the method comprising:
- providing through a surgical instrument a first vacuum pressure;
- receiving an indication of at least a partial occlusion based on a second vacuum pressure that is greater than the first vacuum pressure;
- and
- providing through the surgical instrument a change of one or more parameters from the group consisting of power level, aspiration rate, pump ramp rate, and sound level, in accordance with the indication.
A method for managing occlusions during phacoemulsification surgery, the method comprising:
- providing, by a surgical console having at least one system bus communicatively connected to at least one computing processor capable of accessing at least one computing memory associated with the at least one computing processor, a vacuum system comprising three regions capable of providing vacuum pressure between a minimum pressure and a maximum pressure;
- receiving a first pressure threshold setting and a second pressure threshold setting, wherein the first pressure threshold setting is greater than the minimum pressure and less than the second pressure threshold setting and wherein the second pressure threshold setting is less than the maximum pressure;
- displaying, on a graphical user interface, current aspiration, vacuum, and power settings;
- wherein the three regions capable of providing vacuum pressure are normal state, weak occlusion state, and strong occlusion state;
- wherein each of the three regions possess respective settings comprising power level, pressure, and pressure threshold;
- wherein the normal state is between the minimum pressure and the first pressure threshold, the weak-occlusion state is between the first pressure threshold and the second pressure threshold, and the strong occlusion state is between the second pressure threshold and the maximum pressure.
