Abstract: An electrosurgical device that comprises a deployable electrode tip and concurrent smoke evacuation and suction control integrated in a single apparatus. An electrode tip is supported for motion so that when a selected button is pressed, the tip extends past a suction tube and is activated for cutting and/or coagulating tissue. In this configuration, the suction tube is in a useful position to evacuate surgical site smoke. When pressure on the selected button is released, the tip moves into a retracted position and is deactivated. This allows for the suction tube to evacuate any remaining smoke and suction fluid/solid debris at the surgical site. Optional suction tube sizes and configurations with a control valve for finger-modulated suction can be exchangeable as per surgical demands. This device would allow surgeons to smoothly transition from surgical dissection with smoke evacuation to fluid and debris suctioning to optimize the surgical process.

Abstract: A medical data governance system records, secures, and provides appropriate access to all patient data. By concentrating all available relevant medical data into a single source and providing a subset of data to each receiving subsystem with the correct source and time reference, the medical data governance system becomes the true source of data and guarantees the data consistency through the use of block chain signatures. A data recovery scheme allows for missing or incomplete data to be sourced from any server to which patient data is sent, even data sourced from a remote location.
