The invention relates to a treatment instrument and discloses a low-frequency pulse electromagnetic instrument used for treating knee osteoarthritis and a cartilage injury and a system thereof. In the prior art, equipment used for treating the knee osteoarthritis has problems that there is only one signal generation mode; an adjustable scope of a parameter is narrow; a generated magnetic field uniformity degree error is large; a treatment dosage and metering are not accurate; an equipment structure is complex and cost is high; and a dynamic adjusting mechanism lacks. By using the instrument and the system of the invention, the above problems are solved. The equipment comprises a controller, a current signal generator, a solenoid coil, a lifting platform, a three-dimensional scanner and a magnetic field intensity measuring instrument. The current signal generator, the lifting platform, the three-dimensional scanner and the magnetic field intensity measuring instrument are connected to the controller. The current signal generator is connected to the solenoid coil. The instrument and the system are suitable for treating the knee osteoarthritis and the cartilage injury.
Description
technical field [0001] The invention relates to a treatment instrument, in particular to a low-frequency pulse electromagnetic instrument and a system for treating knee osteoarthritis and cartilage damage. Background technique [0002] Osteoarthritis is a chronic joint disease characterized by degeneration of articular cartilage and secondary bone hyperplasia. It tends to occur in the joints with heavy load, among which the knee joint is the most common. Knee osteoarthritis is mainly characterized by synovial inflammation, cartilage degeneration, and subchondral bone reconstruction. Because of its high disability rate and high mortality rate after the onset, it brings a heavy socioeconomic burden to the whole society. Although there are many ways to treat knee osteoarthritis, non-invasive treatment devices are relatively rare. [0003] At present, most low-frequency pulsed electromagnetic therapy devices are mainly used for fracture healing, pain, inflammation control, ost...
