• The probe tip, the PTFE pad, and the grasping section of the THUNDERBEAT
instrument wear due to ultrasonic vibrations. An excessive wear occurs depending
on the way of use during the procedure, which may cause accidental destruction or
deterioration of coagulating, coagulating/cutting, sealing, or sealing/cutting
performances. To avoid such an event, be sure to prepare a spare
THUNDERBEAT instrument, torque wrench, and stabilizer.
• Do not use the THUNDERBEAT to seal a blood vessel with a diameter over 7 mm.
Otherwise, sufficient sealing may not be achieved.
• Even when using this instrument on blood vessel(s) with diameter of 7 mm or less,
coagulation or sealing by the instrument could be insufficient, and patient bleeding
may result. Depending on the condition of the patient or the blood vessel(s) and
usage of THUNDERBEAT. When using this instrument on blood vessel(s) with a
diameter over 4 mm, be careful to avoid rebleeding. The recommended output
setting for the Seal & Cut mode is level 1, and/or the recommended output setting
for the Seal mode is level 3.
