A system and method for operating a touchscreen of a gas-enhanced electrosurgical generator. The generator has a display module and a primary controller. The display module has a plurality of touch sensors, a PCB power relay and a CPU. The method comprises selecting electrosurgery settings through a graphical user interface, activating through an input device plasma delivery from the gas-enhanced electrosurgical generator, disabling the plurality of touch sensors through software running on the primary controller, disconnecting power from the plurality of touch sensors with the PCB power relay in response to the disabling of the plurality of touch sensors, applying power to an electrode in the plasma accessory connected to the gas-enhanced electrosurgical generator, and de-activating through an input device plasma delivery from the gas-enhanced electrosurgical generator to the plasma accessory connected to the gas-enhanced electrosurgical generator.

A laparoscopic ultrapolar electrosurgery device having both active and return electrodes that reduces potential injury to patients during laparoscopic surgery by eliminating capacitive coupling when employing an electrosurgical handpiece device for cutting and / or coagulating tissue.

Methods and systems for treating biological tissue using high frequency electrical energy includes a cycle comprising a desiccating phase, a cutting phase and a coagulating phase. During the desiccating phase of the cycle, a first high frequency electrical energy applied to the tissue for desiccating the tissue is modulated. A first parameter associated with application of the first high frequency electrical energy to the tissue for desiccating the tissue is estimated. During the cutting phase, cutting energy applied to the tissue for cutting the tissue is then modulated based on the first parameter. During the coagulating phase, a second high frequency electrical energy applied to the tissue for coagulating the cut tissue is modulated.

The present disclosure includes a device having first and second electrodes that include the anti-smoke layer, which can be a hydrophobic layer to aid in reduction of smoke production during operation.

There is a need in the art for synthetic tissue models that not only simulate the tactile properties of tissues and organs but further withstand and respond in an analogous fashion to the application of energy, particularly heat and electrical energy such as accompany electrosurgery. Described herein are materials and methods useful in the construction of synthetic tissue models, particularly conductive synthetic tissue materials made from a state-sensitive, cross-linked polymer composition, that have utility in connection with thermal treatment training and simulation exercises, and moreover provide a current controlled treatment field profile analogous to that of existing tissue to that of the present invention. To that end, the simulated tissues and anatomical models of the present invention are fabricated from a hydrogel composition that undergoes partial or complete transition from its native state prior to treatment (e.g., thermal or non-thermal treatment) to one or more other states when exposed to energy, including but not limited to the following state transitions: discoloration, denaturation, coagulation, carbonization, vaporization, melting or other energy-induced state transition. These transitions facilitate the generating and detecting of a lifelike treatment field profile.

Methods and systems for treating biological tissue using high frequency electrical energy includes a cycle comprising a desiccating phase, a cutting phase and a coagulating phase. During the dessicating phase of the cycle, a first high frequency electrical energy applied to the tissue for desiccating the tissue is modulated. A first parameter associated with application of the first high frequency electrical energy to the tissue for desiccating the tissue is estimated. During the cutting phase, cutting energy applied to the tissue for cutting the tissue is then modulated based on the first parameter. During the coagulating phase, a second high frequency electrical energy applied to the tissue for coagulating the cut tissue is modulated.

An all-in-one body contouring system is provided for performing infiltration, ultrasound-assisted liposuction, aspiration, powered liposuction, skin tightening, fat transfer, and electrosurgery within a single integrated platform. The system includes modular subsystems coordinated by at least one central controller and user interface. An aspiration subsystem employs dual pumps operable in independent or series modes to optimize vacuum performance for single or multi-user operation. A powered liposuction subsystem includes a multi-button handpiece allowing independent activation of infiltration, aspiration, or reciprocation for improved procedural flexibility. Multi-user synchronization software enables two surgeons to operate separate subsystems simultaneously with real-time coordination of shared resources. Graphical user interfaces display live system parameters, procedural sequencing, and safety alerts. The system's control architecture dynamically manages mode switching, power regulation, and vacuum distribution to enhance procedural efficiency, safety, and ergonomics in aesthetic and reconstructive body contouring procedures.
