20220249282 · 2022-08-11 ·

An ultrasonic aspiration and irrigation integrated device, comprising a housing, a horn placed inside the housing, an inner needle tube and an outer needle sleeve extended at the distal end of the housing, and the outer needle sleeve is attached to the outside of the inner needle tube. The bore inside the inner needle tube is part of an aspiration line, the gap between the inner wall of the outer needle sleeve and the outer wall of the inner needle tube is part of an irrigation line, and at the distal ends of the aspiration line and the irrigation line form a junction area. The distal front opening of the inner needle tube to make contact with the irrigation fluid, and the ultrasonic vibration at the inner needle tube distal end produces bubble cavity then explosion, i.e., ultrasonic cavitation, by which to break, liquefy and then aspirate out the target tissue body; the outer sleeve and the provided irrigation liquid effectively enhance the efficiency of tissue liquefaction and extraction, in the meantime minimize the damage of the ultrasonic vibration to the tissue around the needle and reduce the heat generation and its damage.

Features to promote removal of debris from within ultrasonic surgical instrument

An instrument includes an ultrasonic blade, a first fluid port, an irrigation member, a second fluid port, and a fluid communication assembly. The ultrasonic blade defines a distal opening. The ultrasonic blade is operable in a first mode to emulsify tissue that is distally positioned relative to the ultrasonic blade. The ultrasonic blade is further operable in a second mode to transect and seal tissue that is transversely positioned relative to the ultrasonic blade. The first fluid port is in communication with the distal opening of the ultrasonic blade. The irrigation member is positioned adjacent to the distal end of the ultrasonic blade. The second fluid port is in communication with the irrigation member. The fluid communication assembly is configured to couple the first fluid port with a fluid source, couple the first fluid port with a suction source, and couple the second fluid port with the fluid source.

System and method to augment irrigation pressure and to maintain IOP during post occlusion surge

Variables of a surgical system are detected or received via one or more sensors to predict an intraocular pressure (IOP) and/or determine an IOP in real time during a surgical procedure. A notification to a surgeon or a target IOP is set and maintained as determined by Static IOP, dynamic IOP, and/or a total IOP combining both static and dynamic IOP of the anterior chamber of a patient's eye. Information collected about various components of the system are displayed on a user interface. The system uses the collected information to calculate the static IOP and/or dynamic IOP of the system, and the total IOP may be function of the static IOP and/or dynamic IOP measurements.
