The MaxSurgery III is an ultrasonic surgical system (piezosurgery device) manufactured by Guilin Refine Medical Instrument Co., Ltd. for use in minimally invasive bone surgery, primarily in dental and maxillofacial applications. 

Key Features

• Minimally Invasive: The device utilizes micron-level ultrasonic vibrations (at a frequency of 26±3kHz) to cut bone tissue with high precision, minimizing damage to surrounding soft tissues like nerves and blood vessels. This results in smaller incisions (as minimal as 3.5mm x 0.5mm), less post-operative pain, and faster patient recovery.
• Selective Cutting: High-intensity focused ultrasound selectively cuts bone tissue of a specific hardness, while leaving soft tissue unharmed. It also helps in stopping wound bleeding.
• Multiple Operating Modes: The unit features four distinct modes, selectable via a touch control panel:
• B (Bone-cutting)
• P (Periodontal treatment)
• E (Endodontic treatment)
• C (Cleaning)
• Integrated Cooling System: A special spray cooling system using sterile saline flushes the surgical area, removing bone debris, providing a clearer surgical field, and reducing the risk of cross-infection.
• User-Friendly Design: It features an intuitive touch screen interface, a multi-function foot pedal for adjusting power and water flow, and autoclavable components (handpiece and cable) to ensure sterility. 

Range of Applications

The MaxSurgery III is widely used across various surgical fields: 

• Oral Surgery: Minimally invasive tooth extractions (especially impacted or supernumerary teeth), alveolar bone trimming, and maxillary sinus lifts.
• Implantology: Bone splitting, implant site preparation, autologous bone grafting, and bone mass osteotomy.
• Periodontal Surgery: Crown lengthening and root planing.
• Endodontic Surgery: Apicoectomy and apical inverted filling.
• Maxillofacial Surgery: Orthognathic surgery and extraction of cysts or tumors.
• Other Fields: Orthopedic, cosmetic, neurosurgery, and otolaryngology.
