Abstract: Systems, devices, and methods are operable to track usage of a surgical instrument and modify the performance of the surgical instrument based on the prior usage of the surgical instrument. Some surgical instruments are designed to have a limited service life beginning at their first use, or a limit to their overall usage in order to ensure safe use of the sensitive instruments. However, a lack of ability to track usage characteristics when the instrument is separated from an external power supply allows for user abuse and avoidance of such safety mechanisms. Adding a battery or capacitor to the instrument may allow for an ability to track usage when the instrument is separated from an external power supply. Implementing special user prompts, device use ratios, and device use half-life upon powering down of an instrument may additionally be used to prevent circumvention of safety features.

Abstract: An intra-oral device includes a tongue shield aspirator, a bite member, a bite grip, and an evacuation tube. The tongue shield aspirator may include a tongue retractor portion and a cheek retractor portion, and may be an open, unitary, and/or flexible component made of position-memory material. The bite member includes a conduit which receives the tongue shield aspirator through one end and the evacuation tube through the opposite end. The free end of the evacuation tube is connectable directly to a HVE valve to aspirate fluid/debris from the mouth. The device may be positioned in the mouth by bending the distal (free) end of the tongue shield aspirator, inserting the bite member into the mouth first, followed by the tongue shield aspirator as the device is moved towards the patient's cheek, releasing the free end of the tongue shield aspirator, and having the patient bite down on the bite member.
