Embodiment Construction

[0012] Next, one embodiment for carrying out the present invention will be described with reference to the drawings.

[0013] An ultrasonic treatment system for joints (hereinafter referred to as a treatment system) will be described.

[0014] figure 1 is a block diagram of the treatment system 100 .

[0015] The treatment system 100 includes an ultrasonic treatment instrument for joints (hereinafter referred to as a treatment instrument) 1 , a control unit 2 , and an operation unit 3 .

[0016] The treatment instrument 1 has a probe 11 and a vibrator 12 .

[0017] The probe 11 is an example of a vibration transmission unit that transmits ultrasonic vibrations. The probe 11 cuts the cartilage to be treated in the joint or the bone composed of cortical bone and cancellous bone by using the treatment part 1151 described later at the distal end of the probe 11 by transmitting ultrasonic vibrations. The composition of cartilage is different from that of cortical bone and cance...

Abstract

The ultrasonic treatment device for joints has a bone cutting mode vibrating at a first frequency and a first amplitude, and a cartilage dissolving mode vibrating at a second frequency and a second amplitude, and a cartilage dissolving mode, The second frequency is a frequency higher than the first frequency, the second amplitude is smaller than the first amplitude, wherein the first vibration velocity which is the product of the first frequency and the first amplitude is the same as A second vibration velocity that is a product of the second frequency and the second amplitude coincides or substantially coincides.

Description

technical field [0001] The invention relates to an ultrasonic treatment device for joints and an ultrasonic treatment system for joints. Background technique [0002] As an ultrasonic treatment instrument, an ultrasonic treatment instrument capable of cutting bone and cartilage is known, for example, as disclosed in JP-A-2003-116870. Such an ultrasonic treatment instrument has both the function of cutting by mechanical vibration (hereinafter referred to as hammer effect) and the function of cutting (dissolving) tissue by using frictional heat. [0003] In recent years, studies have been conducted on the use of ultrasonic treatment instruments for joint treatment. Joints have cartilage and a skeleton consisting of cortical and cancellous bone. Ultrasonic treatment instruments are used not only for treatment of cartilage but also for treatment of cortical bone and cancellous bone. [0004] It is known that the resection mechanism of cartilage differs from that of cortical b...
