Patent number: 11883059Abstract: An ultrasonic surgical instrument includes a first modular assembly including at least one operator input feature an ultrasonic transducer supported by the first modular assembly, and a second modular assembly configured to be removably coupled with the first modular assembly. The second modular assembly includes at least a portion of an end effector extending distally from a distal end portion of the second modular assembly. The instrument includes a mechanical lockout assembly configured to switch between at least an unlocked configuration and a locked configuration. In the locked configuration, the first modular assembly and the second modular assembly are partially coupled together such that the operator is physically prevented from activating the instrument using the operator input feature. In the unlocked configuration, the first modular assembly and the second modular assembly are completely coupled together and the operator is able to activate the instrument using the operator input feature.Type: GrantFiled: February 4, 2021Date of Patent: January 30, 2024Assignee: Cilag GmbH InternationalInventors: John E.

Publication number: 20240000474Abstract: A surgical instrument includes a shaft assembly, an end effector, an energy drive system, a circuit assembly, and a body assembly. Body assembly has a first shroud portion removably affixed to a second shroud portion by a shroud coupling in a connected state. The shroud coupling detaches the first shroud portion from the second shroud portion in a disconnected state. The first and second shroud portions in the connected state encloses and inhibits access to at least a portion of at least one of the circuit assembly or the energy drive system. The first and second shroud portions in the disconnected state allow access to the at least the portion of at least one of the circuit assembly or the energy drive system for removal of the at least the portion of at least one of the circuit assembly or the energy drive system.Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Inventors: Frederick E.

Patent number: 11696781Abstract: A surgical instrument includes a body, a shaft assembly, an end effector, a clamp actuator, and a blade cooling system. The end effector has a clamp arm and an ultrasonic blade coupled with an ultrasonic transducer. The clamp arm is configured to selectively move from a first actuator position toward a second actuator position thereby directing movement of the clamp arm from the open position toward the closed position, respectively. The cooling system is operable to deliver fluid coolant to the ultrasonic blade to thereby cool the ultrasonic blade while the clamp actuator remains in the first actuator position.Type: GrantFiled: July 26, 2021Date of Patent: July 11, 2023Assignee: Cilag GmbH InternationalInventors: Jeffery D.

Publication number: 20210196334Abstract: Disclosed is a surgical instrument with an end-effector adapted and configured to deliver a plurality of energy modalities to tissue at a distal end thereof. The energy modalities may be applied simultaneously, independently, or sequentially. A generator is electrically coupled to the surgical instrument and is configured to supply a plurality of energy modalities to the end-effector. In one aspect, the generator is configured to supply electrosurgical energy (e.g., monopolar or bipolar radio frequency (RF) energy) and ultrasonic energy to the end-effector to allow the end-effector to interact with the tissue. The energy modalities may be supplied to the end-effector by a single generator or multiple generators.Type: ApplicationFiled: May 29, 2020Publication date: July 1, 2021Inventors: John M.
