Abstract: An arthroscopic surgery method for ankle ligament reconstruction of this embodiment is removed using an ultrasonic treatment tool, blowing away a synovial membrane, and secures the view for a remnant ligament. Then, bone holes are produced to a fibula, a talus and a calcaneus using the ultrasonic treatment tool.

Abstract: An ultrasonic surgical system includes an ultrasonic transducer, a probe, and at least one circuit. The ultrasonic transducer is designed to ultrasonically vibrate. The probe is coupled to the ultrasonic transducer and is designed to treat a living tissue by the ultrasonic vibration. The circuit performs functions including detecting a pressing force of the probe against the living tissue, calculating a value of a product of the pressing force, an amplitude of the ultrasonic vibration, and a resonance frequency of the probe, comparing the calculated value with a predetermined product value, and generating a predetermined signal based on a result of the comparison.

Abstract: A treatment method is a treatment method for cutting cartilage of a human body by an ultrasonic device including a cutting section that ultrasonically vibrates. The treatment method includes cutting the cartilage with a product of an amplitude of the cutting section and a pressing force for pressing the cutting section against the cartilage being 100 (N·μm) or larger.

Abstract: A surgical treatment of an ACL or a PCL of a knee joint under an arthroscope, includes: contacting a treating portion of an ultrasonic device with a start region to which the ACL or the PCL of a femur adheres, and excising the femur and a remaining ligament of the ACL, or the femur and a remaining ligament of the PCL by ultrasonically vibrating the treating portion, thereby exposing a footprint of the femur; and contacting the treating portion with an end region to which the ACL or the PCL of a tibia adheres, and excising the tibia and a remaining ligament of the ACL, or the tibia and a remaining ligament of the PCL by ultrasonically vibrating the treating portion, thereby exposing a footprint of the tibia.

Abstract: A surgical treatment of a ligament of a knee joint under an arthroscope, includes: forming concave holes from the region of the tibia to which the ligament adheres toward an inner side of a rough surface of the tibia and from the region of the femur to which the ligament adheres toward an outer surface of a lateral condyle of the femur by ultrasonically vibrating the treating portion; forming tunnels between the concave hole of the tibia and the medial side of the rough surface of the tibia using the concave hole of the tibia and between the concave hole of the femur and the lateral surface of the lateral condyle of the femur using the concave hole of the femur.
