4.2. Wound Debridement Applications / Use (e.g. SonicOne applications)
Debridement probes are typically used for contact wound debridement. Tissue excision and fragmentation are
achieved through cavitation and other mechanical and hydrodynamic effects.
Recommended Settings
The following settings are general guidelines and should be adjusted based on indication, anatomy, pathology and
surgeon’s preference.

2 – The lowest flow setting is 5
Table 4.2.1: Wound Debridement Setting Recommendations
•
A high amplitude setting results in more aggressive tissue removal, a low setting in less aggressive tissue removal.
•
A higher amplitude setting in combination with lower irrigation could result in tissue necrosis.
•
A lower amplitude setting in combination with higher irrigation would reduce the potential for tissue necrosis.
•
The various disposable attachments (i.e. debridement probes, etc…) are considered the applied part.
4.3 Soft Tissue Applications / Use (e.g. SonaStar Applications)
Aspiration
probes are typically used for soft tissue removal. Tissue excision and fragmentation are achieved through
cavitation and other mechanical and hydrodynamic effects.
Recommended Settings
The following settings are general guidelines and should be adjusted based on indication, anatomy, pathology and
surgeon’s preference.

* At Amplitude setting 0, ultrasound is disabled. The lowest Flow and Aspiration setting is 5. See specification table for the applicable flow
rate.
