Method for controlling an energy module output
(57) Abstract

A method for controlling an output of an energy module of a modular energy system. The energy module can comprise a plurality of amplifiers configured to generate a drive signal at a frequency range and a plurality of ports coupled to the plurality of amplifiers. The method includes determining to which port of the plurality of ports the surgical instrument is connected, selectively coupling an amplifier of the plurality of amplifiers to the port of the plurality of ports to which the surgical instrument is connected, and controlling the amplifier to deliver the drive signal for driving the energy modality to the surgical instrument through the port.

Description

The present disclosure relates to various surgical systems, including modular electrosurgical and/or ultrasonic surgical systems. Operating rooms (ORs) are in need of streamlined capital solutions because ORs are a tangled web of cords, devices, and people due to the number of different devices that are needed to complete each surgical procedure. This is a reality of every OR in every market throughout the globe. Capital equipment is a major offender in creating clutter within ORs because most capital equipment performs one task or job, and each type of capital equipment requires unique techniques or methods to use and has a unique user interface. Accordingly, there are unmet consumer needs for capital equipment and other surgical technology to be consolidated in order to decrease the equipment footprint within the OR, streamline the equipment's interfaces, and improve surgical staff efficiency during a surgical procedure by reducing the number of devices that surgical staff members need to interact with.

In one general aspect, a method for controlling an output of an energy module of a modular energy system. The energy module can comprise a plurality of amplifiers and a plurality of ports coupled to the plurality of amplifiers. Each of the plurality of amplifiers can be configured to generate a drive signal at a frequency range. Each of the plurality of ports can be configured to drive an energy modality for a surgical instrument connected thereto according to each drive signal.

  "description_excerpt": "The present disclosure relates to various surgical systems, including modular electrosurgical and/or ultrasonic surgical systems. Operating rooms (ORs) are in need of streamlined capital solutions because ORs are a tangled web of cords, devices, and people due to the number of different devices that are needed to complete each surgical procedure. This is a reality of every OR in every market throughout the globe. Capital equipment is a major offender in creating clutter within ORs because most capital equipment performs one task or job, and each type of capital equipment requires unique techniques or methods to use and has a unique user interface. Accordingly, there are unmet consumer needs for capital equipment and other surgical technology to be consolidated in order to decrease the equipment footprint within the OR, streamline the equipment's interfaces, and improve surgical staff efficiency during a surgical procedure by reducing the number of devices that surgical staff members need to interact with.\n\nIn one general aspect, a method for controlling an output of an energy module of a modular energy system. The energy module can comprise a plurality of amplifiers and a plurality of ports coupled to the plurality of amplifiers. Each of the plurality of amplifiers can be configured to generate a drive signal at a frequency range. Each of the plurality of ports can be configured to drive an energy modality for a surgical instrument connected thereto according to each drive signal.",
