• When applying energy to a blood vessel, confirm that the distal end of the shaft is
not submerged in fluids such as pooled blood or saline. Such conditions could
potentially reduce the effectiveness of the THUNDERBEAT and could cause
unintended tissue damage.
• Do not activate the THUNDERBEAT simultaneously during suctioning and/or
irrigating the surgical site. Otherwise, an unexpected current path may cause
unintended tissue burns or degradation of treatment performance.
• When a body fluid or tissue is present on the grasping section, probe tip or shaft
surface during the procedure, immediately withdraw it by immersing the grasping
section and probe tip in saline or wiping with sterile gauze. Otherwise, the
performance may be degraded. Failure to maintain a clean grasping section may
result in the grasping section becoming hard to open or close, and the load
imposed on the distal end of the grasping section may cause vibration failure or
other issues.
• The THUNDERBEAT gives priority to the function of a switch pushed earlier.
During the procedure, be very careful not to accidentally activate the handswitch or
footswitch as this may result in unintentional coagulation or cutting of tissue.
Particularly, never mistake the SEAL & CUT button for the SEAL button because
this may lead to unintentional cutting of tissue.
• During the seal mode, do not stop activation until the “SEAL Complete” tone is
heard. Otherwise, the target tissue may not be coagulated and may bleed.
• If the grasping section, the PTFE pad, or the probe tip falls off, stop using the
THUNDERBEAT immediately and retrieve it by appropriate means.
