Ultrasonic focusing device for treating Parkinson's disease

Abstract

The invention discloses an ultrasonic focusing device for treating a Parkinson's disease. The ultrasonic focusing device is formed by a magnetic resonance scanning device, an ultrasonic transmitting device, an ultrasonic information setting device, an ultrasonic development device, a magnetic resonance information converting device and an magnetic resonance image display system. The magnetic resonance scanning device is connected with the magnetic resonance information converting device, the magnetic resonance image display system and the ultrasonic information setting device, and the ultrasonic information setting device is connected with the ultrasonic transmitting device and the ultrasonic development device. The ultrasonic focusing device utilizes functional magnetic resonance to position brain structures and is accurate in positioning.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to an ultrasonic confocal equipment for treating Parkinson's syndrome. Background technique [0002] Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by bradykinesia, rigidity, tremor at rest, trunk prodromal tendency, and unsteady standing. [0003] Clinically, surgical implantation of deep brain stimulation (deep brain stimulation, DBS, commonly known as: brain pacemaker) is used to enhance the excitability of the substantia nigra and increase the activity of DA. At present, due to nuclear magnetic resonance imaging MRI and (computerized X-ray tomography technology) can accurately locate the various nerve nuclei of the brain (including the substantia nigra and striatum. In recent years, due to the development of molecular imaging, some nerve cells in the nucleus can be accurately located. Functional phenomena. In addition to deep brain pa...

Problems solved by technology

In addition, treatments such as transcranial electrical stimulation have been used in PD treatment, but the efficacy is uncertain

[0004] Brain pacemakers have the following disadvantages: microelectrodes are implanted in the inner core of the brain to improve symptoms, cerebral hemorrhage and cerebral edema may occur after surgery, and symptoms recur within a period of time in some patients; severe cardiopulmonary and kidney diseases, uncontrollable high It is not suitable for patients with blood pressure and mental symptoms; in addition, it is expensive. At present, unilateral treatment costs about 100,000 yuan, and bilateral treatment costs about 200,000 yuan. The battery needs to be replaced regularly, and the cost is high. It is often difficult for ordinary patients. withstand; at the same time prone to equipment failure

This solution overcomes the possibility of cerebral hemorrhage and cerebral edema after the brain pacemaker; it is not suitable for patients with severe cardiopulmonary and kidney diseases, uncontrollable high blood pressure and mental symptoms; in addition, the cost is expensive and the defects of equipment failure

Disadvantages of radiofrequency thermal coagulation damage treatment: the damage range is difficult to be limited to a small range (about 100 microns), which may damage the peripheral nerve structure and cause important functional abnormalities
