Problems solved by technology

Surgical resection of the necrotic part is to remove the hardened end and fibrous tissue of the nonunion part to form a fresh fracture and bone graft to treat nonunion. This method has a certain effect, but it cannot treat refractory nonunion
The method of intramedullary nailing and bone grafting has been widely used in recent years, but the operation is complicated, and the patient suffers a lot of pain, and this method cannot be applied to chronic osteomyelitis, nonunion of irreversible damage to muscles, tendons, nerves, and blood vessels. patient
Core decompression surgery, trying to extract red bone marrow to extract stem cells and inject them into the necrotic area to treat necrosis of the femoral head, but the current dosage and effect of this method are not clear, and once the femoral head collapses, it is no longer possible to use stem cells for treatment

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Please refer to FIG. 1 , which is a schematic structural diagram of the bone healing therapeutic apparatus of the present invention. The bone healing therapeutic instrument 100 includes a keyboard 1, a liquid crystal display 2, an AVR microcontroller 3, two programmable sine wave generators 4, two digital / analog converters 5, two integrated operational amplifiers 6 and electrodes a, b, c and d. Wherein, the model of the sine wave generator 4 is ML2035, and the model of the digital / analog converter 5 is DAC0832. The keyboard 1 realizes the start / stop of the bone healing therapeutic apparatus 100, and realizes the decrease and increase of the maximum voltage range, the minimum voltage is 0V, and the maximum voltage is ±15V. The liquid crystal display 2 displays the operating state, voltage amplitude and frequency of the bone healing ther...

Abstract

The invention discloses a bone healing treatment instrument, which comprises a power generating device and an output electrode. The power producing device transmits series of sine wave electrical signals to the output electrode, which then produces an electric filed (frequency ranging from 80Hz to 120Hz) to take effect on the bone nonunion parts. The invention also discloses a bone healing treatment. The instrument can stimulate the bone nonunion parts with the low frequency (80Hz to 120Hz) signals, and accelerate the bone callus growing. The invention can significantly improve the partial skin pain threshold, and distend the partial telangiectasia. At the same time, the invention has good stimulation effect on the motor nerve and the muscle tissue, and accelerates the bone nonunion healing in various ways with little skin irritation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a bone healing treatment instrument and a bone healing treatment method. Background technique [0002] The current trend in the treatment of nonunions in the world can basically be divided into three parts, namely: surgical resection of necrotic parts, intramedullary nailing and bone grafting, and percutaneous injection of red bone marrow. Surgical resection of the necrotic part is to remove the hardened end and fibrous tissue of the nonunion part to form a fresh fracture and bone graft to treat nonunion. This method has a certain effect, but it cannot treat refractory nonunion. The method of intramedullary nailing and bone grafting has been widely used in recent years, but the operation is complicated, and the patient suffers a lot of pain, and this method cannot be applied to chronic osteomyelitis, nonunion of irreversible damage to muscles, tendons, nerves, and blood vessels. p...
