A method of surgery includes inserting a surgical instrument into a surgical site, supplying energy from a surgical generator to tissue at the surgical site via the surgical instrument to treat the tissue, sensing at least one property of smoke at the surgical site, and determining at least one parameter of smoke at the surgical site based upon the at least one property. The method further includes controlling the supply of energy from the surgical generator based upon the at least one parameter and/or providing an output based upon the at least one parameter.

The present invention relates to a treatment apparatus and a method of controlling the same. There are provided a treatment apparatus, including a handpiece, an RF generator generating RF energy, an insertion unit configured to advance and retract toward one direction of the handpiece, selectively inserted into a tissue, and electrically connected to the RF generator to transfer the RF energy to the inside of the tissue, and a substance storage unit receiving a therapeutic substance therein and detachably installed on one side of the handpiece to transfer the substance to the inside of the tissue by the advancing operation of the insertion unit and a method of controlling the same.

A surgical clip applier is disclosed which is configured to automatically feed a clip from a clip cartridge once the surgical clip applier is positioned in the patient.

An electrosurgical system comprising an end effector and a control circuit is disclosed. The end effector comprises a first jaw and a second jaw. At least one of the first jaw and the second jaw is movable to transition the end effector from an open configuration to a closed configuration to grasp tissue therebetween. The control circuit is configured to cause an application of two different energy modalities to the tissue simultaneously and separately during a tissue treatment cycle comprising a tissue coagulation stage and a tissue transection stage.

A surgical pump assembly includes a motor configured to provide a motor output, a transmission assembly configured to receive the motor output and provide a plurality of transmission outputs, and a plurality of pumps. Each pump of the plurality of pumps is configured to receive one of the transmission outputs of the plurality of transmission outputs. A surgical generator includes at least one energy module configured to generate an energy-delivery signal, at least one energy port configured to connect to a surgical instrument to deliver the energy-delivery signal thereto, and the surgical pump assembly.

A cold plasma device is suitable for treating a region of a biological surface. The device includes a cold plasma generator with an electrode and a dielectric barrier. The dielectric barrier includes a first side that faces the electrode and a second side that faces away from the electrode. An actuator is configured to selectively reciprocate the cold plasma generator between a first position and a second position, and a controller is programmed to control the actuator to selectively position the cold plasma generator relative to the biological surface.

A catheter system for treating a treatment site within or adjacent to a vessel wall or a heart valve within a body of a patient includes an energy source, an inflatable balloon, an energy guide, and an acoustic sensor. The energy source generates energy. The inflatable balloon is positionable substantially adjacent to the treatment site. The inflatable balloon has a balloon wall that defines a balloon interior that receives a balloon fluid. The energy guide receives energy from the energy source and guides the energy into the balloon interior. The acoustic sensor is positioned outside the body of the patient. The acoustic sensor senses acoustic sound waves generated in the balloon fluid within the balloon interior. The acoustic sensor generates a sensor signal based at least in part on the sensed acoustic sound waves. A system controller receives the sensor signal from the acoustic sensor and controls operation of the catheter system based at least in part on the sensor signal.

A surgical system comprising a surgical hub, a surgical instrument, a generator configured to energize an end effector; and a smoke evacuation system configured to remove smoke from a surgical site is disclosed. The surgical instrument comprises the end effector. A control command is passed directly from the surgical hub to the surgical instrument. The surgical instrument is configured to pass the control command received from the surgical hub to the generator and the smoke evacuation system in a daisy-chain manner.

A surgical system comprising a surgical instrument, a generator configured to supply power to an end effector, and a processor configured to run a control program to operate the surgical system is disclosed. The surgical instrument comprises the end effector which includes a first jaw and a second jaw. At least one of the first jaw and the second jaw is moved with respect to one another between an open position and a closed position. Tissue is configured to be positioned between the first jaw and the second jaw. The processor is configured to detect a first parameter of the surgical system, detect at least one user input, and modify the control program in response to the detected first parameter and the at least one user input.

A surgical instrument comprising a housing, a shaft assembly, a processor, and a memory is disclosed. The shaft assembly is replaceably connected to the housing. The shaft assembly comprises an end effector. The memory is configured to store program instructions which, when executed from the memory cause the processor to send an electrical interrogation signal to the attached shaft assembly, receive a response signal from the attached shaft assembly, cause a default function to be performed when a response signal is not received by the attached shaft assembly, determine an identifying characteristic of the attached shaft assembly as a result of the performance of the default function, and modify a control program based on the identifying characteristic of the attached shaft assembly.
