Confirm that the voltage selector switch on the console rear panel is set to the local voltage setting and ensure that the correct fuses are being used. Refer to section 12.1 on instructions for fuse replacement.
WARNING 3.1
Tip and irrigant temperatures may exceed the tissue necrosis point if insufficient irrigation flow rates are used. For hard tissue removal , set the irrigation flowrate to a setting no less than the comparable vibration setting. For example, if the vibration setting is 7, a minimum flow setting of 70% should be used. Additional external irrigation, e.g. by administering sterile saline with a syringe over the distal tip portion, may be necessary for removal of very dense, hard osseous structures.
WARNING 3.2
Tissue necrosis may result if tip is not moved relative to tissue. A continuous, lateral sweeping motion is recommended in order to minimize contact duration with the ultrasonic tip and minimize heat build-up. When lateral motion is not possible withdraw and re-insert tip frequently.
WARNING 4.1
Contact to vibrating elements like extension and ultrasonic tip may cause burns and should be avoided by all means. The handpiece should only be held at the black housing area. An optional, protective silicone sleeve, included with certain tips, reduces the risk of thermal damage but does not eliminate it. Contact with the silicone sleeve should be avoided or kept brief with minimal amount of contact pressure. Pressure and extended exposure can still result in excessive frictional heat and cause burns.
WARNING 4.2
Additional external irrigation, e.g. by administering sterile saline with a syringe over the distal tip portion, may be necessary for removal of very dense, hard osseous structures of the skull, when using the BoneScalpel accessories.
WARNING 4.3
Ultrasonic tips can break under excessive use in extreme conditions, e.g. when cutting for extended duration in tight cavities with limited lateral motion. The tip could break into two or more fragments with the main fragment remaining attached to the handpiece. All fragments must be retrieved immediately from the surgical site. The fragments should be checked to ensure that no further pieces are missing. It is possible that a fragment is propelled outside of the surgical cavity. Diagnostic imaging, such as X-ray, must be used if a fragment cannot be found to confirm that the broken piece is outside of the surgical cavity.
WARNING 4.4
Breakage of ultrasonic tips will result in sharp edges that can be harmful to soft tissue even without activation of ultrasound. Tips can bend or deform before they actually brake. Tips showing signs of deformation or cracking should be replaced immediately since tip breakage is otherwise imminent. Do not bend or twist the ultrasonic tips since it reduces the structural integrity and can result in tip breakage during use. Dispose of deformed or broken tips immediately in a sharps container.
WARNING 6.1
Immediately suspend operation if Electrical Fault appears on display and/or an Electrical Fault audible Indicator sounds. Remove ultrasonic tip from surgical site. Turn Mains Power OFF. Do not touch any metallic parts of handpiece, extension, ultrasonic tip or generator while fault is indicated.
WARNING 7.1
Improper connection of the handpiece cable may present a shock hazard. Confirm that handpiece connector is dry prior to plugging it in.
WARNING 7.2
Do not operate pump with pump cover in raised position. Rollers might pinch loose clothing or fingers. Personal injuries may result. Cooling of the ultrasonic tip and irrigation at the treatment site will be inhibited.
WARNING 7.3
Tip and irrigation temperatures may exceed the tissue necrosis point with BoneScalpel accessories for hard tissue removal if insufficient irrigation flow rates are used. Always set the irrigation flowrate for hard tissue removal to a setting no less than the comparable vibration setting. For example, if the vibration setting is 7, a minimum flow setting of 70% should be used.

3. Adverse Effects CAUTION 3.1
The BoneScalpel system and its accessories may emit harmful acoustic pressure if exposure exceeds recommended limits. Limits For Airborn Acoustic Exposure Minimum Operating Distance Maximum Exposure Period From operator’s or patient’s ear Within a 24hour period 3” - 12” 8 cm – 30 cm Not to exceed 30 minutes 12” - 24” 30 cm – 60 cm Not to exceed 90 minutes > 24” 60 cm Not to exceed 240 minutes
WARNING 3.1
Tip and irrigant temperatures may exceed the tissue necrosis point if insufficient irrigation flow rates are used. For hard tissue removal , set the irrigation flowrate to a setting no less than the comparable vibration setting. For example, if the vibration setting is 7, a minimum flow setting of 70% should be used. Additional external irrigation, e.g. by administering sterile saline with a syringe over the distal tip portion, may be necessary for removal of very dense, hard osseous structures.
WARNING 3.2
Tissue necrosis may result if tip is not moved relative to tissue. A continuous, lateral sweeping motion is recommended in order to minimize contact duration with the ultrasonic tip and minimize heat build-up. When lateral motion is not possible withdraw and re-insert tip frequently.

Incorrect hand position
Contact to vibrating elements like extension and ultrasonic tip may cause burns and should be avoided by all means. The handpiece should only be held at the black housing area. An optional, protective silicone sleeve, included with certain tips, reduces the risk of thermal damage but does not eliminate it. Contact with the silicone sleeve should be

avoided or kept brief with minimal amount of contact pressure. Pressure and extended exposure can still result in excessive frictional heat and cause burns. NOTE 4.1
4.2.
After extended periods of operation, the bottom of the console housing may become warm to the touch. This is normal. Do not touch the bottom of the console housing while in operation or shortly after operation.
HARD Tissue Use
Recommended Settings For Hard Tissue Use The following settings are general guidelines and should be adjusted based on indication, anatomy, pathology and surgeon’s preference.
Highest Very High High Standard (Default) Moderate Low Table 4.1
Amplitude 10 9 8 7 6 5
Pulse 100% 100% 100% 100% 100% 100%
Flow 100% 90% 80% 70% 60% 50%
Recommended settings for hard tissue removal
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 increased tissue necrosis. A lower amplitude setting in combination with higher irrigation would minimize or eliminate tissue necrosis. Bone shaving tips tend to require a lower amplitude than cutting blades.
WARNING 3.1
Tip and irrigant temperatures may exceed the tissue necrosis point if insufficient irrigation flow rates are used. For hard tissue removal , set the irrigation flowrate to a setting no less than the comparable vibration setting. For example, if the vibration setting is 7, a minimum flow setting of 70% should be used. Additional external irrigation, e.g. by administering sterile saline with a syringe over the distal tip portion, may be necessary for removal of very dense, hard osseous structures.
WARNING 3.2
Tissue necrosis may result if tip is not moved relative to tissue. A continuous, lateral sweeping motion is recommended in order to minimize contact duration with the ultrasonic tip and minimize heat build-up. When lateral motion is not possible withdraw and re-insert tip frequently.
WARNING 4.2
Additional external irrigation, e.g. by administering sterile saline with a syringe over the distal tip portion, may be necessary for removal of very dense, hard osseous structures of the skull, when using the BoneScalpel accessories.
CAUTION 4.1
Ultrasonic energy is inhibited if excessive physical force is applied to the ultrasonic tip; use only enough force to guide the tip to the surgical site and to advance it through the tissue. Do not force the tip; allow the ultrasonic action to do the work.

Instructions For Use
Tip Limitations During Bone Removal Both the ultrasonic tip and the extension are vibrating at high frequency and are thus exposed to extreme mechanical stresses, especially when cutting bone.
WARNING 4.3
Ultrasonic tips can break under excessive use in extreme conditions, e.g. when cutting for extended duration in tight cavities with limited lateral motion. The tip could break into two or more fragments with the main fragment remaining attached to the handpiece. All fragments must be retrieved immediately from the surgical site. The fragments should be checked to ensure that no further pieces are missing. It is possible that a fragment is propelled outside of the surgical cavity. Diagnostic imaging, such as X-ray, must be used if a fragment cannot be found to confirm that the broken piece is outside of the surgical cavity.
WARNING 4.4
Breakage of ultrasonic tips will result in sharp edges that can be harmful to soft tissue even without activation of ultrasound. Tips can bend or deform before they actually brake. Tips showing signs of deformation or cracking should be replaced immediately since tip breakage is otherwise imminent. Do not bend or twist the ultrasonic tips since it reduces the structural integrity and can result in tip breakage during use. Dispose of deformed or broken tips immediately in a sharps container.
CAUTION 4.2
Insufficient irrigation and high tip pressure (loading) under extended exposure, e.g. in tight cavities, are to be avoided in BoneScalpel hard tissue removal. It is recommended to withdraw and re-insert the ultrasonic tip repeatedly to reestablish adequate cooling and lubrication.
NOTE 4.2
Loose tip/tissue contact upon an initial bone incision can cause a thin tip to resonate not only longitudinally but also transversely. This can cause a thin tip to break. It is necessary to engage bone actively and with a minimal tip pressure greater than zero in order to prevent the shattering.
NOTE 4.3
Contact of the ultrasonic tip or the exposed extension with metal, surgical instruments or other objects during ultrasound use must be avoided. Such contact can damage the ultrasonic components very easily and may result in compromised performance, including failure. Discard any extensions or tips that show signs of damages like gouges, nicks or fractures. External aspiration may be used but it is recommended that a plastic suction tip should be used when in proximity with the probe tip.
4.3.
SOFT Tissue Use
Recommended Settings For Soft Tissue Use The following settings are general guidelines and should be adjusted based on indication, anatomy, pathology and surgeon’s preference.
Highest Very High Factory default High Moderate Low Very low Lowest Table 4.2
Amplitude 10 8 7 6 5 4 3 2
Pulse 100% 100% 100% 100% 100% 100% 100% 100%
Flow ≥10% ≥10% 70% ≥10% ≥10% ≥10% ≥10% ≥10%
Recommended settings for soft tissue debridement
A high amplitude setting results in more aggressive tissue removal, a low setting in less aggressive tissue removal. A lower amplitude setting in combination with higher irrigation results in less aggressive tissue removal with an increased ability to wash debris from the wound.

5. System Overview 5.1.
Principle Of Operation
The BoneScalpel system is designed to ultrasonically dissect and fragment hard (osseous) and soft tissues. The system consists of an ultrasonic console with handpiece and accessories. The console features an integrated irrigation pump.
Figure 5.1
BoneScalpel Console
Figure 5.2
BoneScalpel Handpiece
The console produces an electrical signal that is fed into the handpiece and its piezoelectric transducer. The transducer converts the electrical signal into mechanical vibrations. The vibratory motion is amplified all the way down to the tip’s distal end. Various tip shapes and sizes are available to achieve desired tissue effects.
Hard Tissue Applications: Specialized hard tissue tips are utilized to cut hard, osseous structures. o
o o
BoneScalpel blades, typically used for performing osteotomies, are usually flat and have a blunt active edge. A compression cut is achieved through repetitive impacts on the bone at an ultrasonic frequency. Bone shaving tips are used for sculpting bone. They have an abrasive surface for bone removal through abrasion under ultrasonic oscillation. BoneScalpel multi-function tips can have a combination of blunt and abrasive cutting surfaces.
Soft Tissue Applications: Specialized soft tissue tips are utilized to cut and fragment soft tissue structures (SonicOne technology). o
Debridement tips are typically used for contact wound debridement. Tissue excision and fragmentation are achieved through cavitation and other mechanical and hydrodynamic effects.
A peristaltic pump, integrated into the BoneScalpel console, provides irrigant (sterile physiological saline) to the operative site during use.
