The Sonicision™ cordless ultrasonic dissection device can be used to coagulate isolated vessels up to 5 mm in diameter.
Both components have internal counters and display different lights when they have reached maximum use life - 100 uses. A flashing red LED indicator on the battery charger and a flashing purple LED indicator on the generator indicate end of useful life for the components. The battery and generator were designed to provide optimal performance throughout their lifespan.
A depleted battery typically takes approximately two hours to fully recharge.
The actual amount of capacity for energy activations depends on many factors including; idle duration, shelf life, and use profile, however our research indicates that one fully-charged Sonicision™ battery should satisfy the majority of procedures when ultrasonic energy is typically used. It is always wise to have a second battery on-hand and available for all cases.
To maintain optimal performance the battery pack should be used as soon as possible after completing charge. However, the battery should be submitted for recharging and sterilization after 30 days of continuous time on the shelf without use
The materials used to house the battery and generator are not designed to withstand the high temperatures experienced in an autoclave system. Exposing the battery and generator to autoclave temperatures will cause the external material to deform, damage the battery cells, and render the components unusable.
Batteries that are colder than 50°F will charge at roughly 10% of the normal charge rate until that battery temperature exceeds 50°F at which time it will return to the normal charging rate.
Battery packs are shipped from Medtronic to the customer with a low charge and in a "deep sleep" state. To avoid damage and ensure the battery pack remains functional, the battery pack should be charged upon initial receipt by the customer.
Based on the processes outlined in our user's guide and feedback from central processing managers, we anticipate the cleaning, charging and sterilization steps will take several hours to complete. In hospitals with on-site central sterile capabilities products may be available for reuse as soon as these steps are completed. For hospitals that contract their central sterile services offsite this may lead to a turn-around time of up to several days. You are encouraged to confirm the specifics of this process with each Sonicision target hospital.
The average time frame is about four hours.
The device will "time out" (stop delivery of energy to tissue) after approximately 20 seconds of continuous activation. This safety feature provides protection against prolonged unintentional activations. When a "time out" occurs during intended use the operator should simply release and re-engage the dual-mode energy activation button.
The yellow LED indicator signals a battery has less than 20% remaining capacity. It is recommended to replace the battery as soon as possible.
The Sonicision™ dissector draws minimal power from the battery when connected but no activated. The battery's life is primarily determined by number of activations.
