Ultrasonic surgical system can be widely used in high-risk surgery: spine surgery, neurosurgery, maxillofacial surgery,ENT, general surgery, etc.
Ultrasonic bone cutter and drill & CUSA integrated platform:
Ultrasonic bone cutter and drill theory：
Ultrasonic handpiece can convert electrical energy into mechanical energy and drive ultrasonic tips to vibrate longitudinally at 40 kHz, and the energy transfer recognizes the type of tissue and responds accordingly through modulating the amount of energy driven into the tissue. When the ultrasonic tip is in contact with the target tissue, it directs a focused amount of energy into it causing the desired effect (such as cutting, sawing, grinding and drilling)
Precision Safety:
No high-speed rotation, can be used for fine cutting, grinding, drilling, planning at high-risk surgical position, little risk to nerve bundle and vascular plexus surrounding bone, reducing the risk of surgery.
Minimal Thermal Damage:
Ultrasonic energy will soften the bone tissue when it direct contact with the tip, then breaks it down. lt’s similar to ultrasonic cutter，which first breaks the bonds of the tissue protein to loosen and soften it, then denatures the bonds. In a similar way this effect generates little heat and thermal spread. The integrated irrigation system also ensures that the temperature of cutting area is kept to minimal and safe levels
Soft Tissue Protection:
Ultrasound bone cutter has tissue-selective energy characteristic during operation, it relies on the tip to be in direct and full contacted with the tissue which feeds back the resonance for maximum transmission of ultrasound energy. lt takes a few seconds to realize the resonance state before the correct amount energy is delivered to the tissue. During bone cutting when the tip comes in contact with soft tissue, it will begin to create a new resonance state for maximum energy transfer, during this2-3 seconds it is sufficient for the surgeon to realize the soft tissue has been encountered by the tip.For safety reasons the amplitude of ultrasonic cutter is kept to a minimum and will not cause stretching and scratching of the soft tissue.
Better Hemostasis:
Ultrasonic bone cutter relies on the softness and deformation of the bone tissue before it is cut, so the area of blood vessels will be protected by the slip deformation of bone tissue, and thus
CUSA advantages:
Excellent Tissue Selectivity: It can breakdown and perform suction of the tissue(such as tumor) simultaneously while preserving blood vessels and nerves. This helps to avoid accidental injury, shorten operation time, reduce bleeding and potential complications during surgery;
Different Blade Tips (especially micro and extended titanium alloy tip) including straight and curved handpiece. This can meet the needs of different procedures and be particularly suitable for micro, minimally invasive operation
