Problems solved by technology

[0005] However, compared with computed tomography imaging examination, radiofrequency thermocoagulation therapy, gamma knife radiosurgery, etc., the diagnosis and treatment of MRI-guided focused ultrasound take relatively longer time. The process of internal fixation typically takes 2 to 4 hours, which will bring more discomfort and even pain to the patient

Abstract

The invention discloses a fixing device used in magnetic resonance imaging-guided focused ultrasound for diagnosing and treating encephalopathy. The fixing device comprises a U-shaped frame plate, an I-shaped plate, a first head cage frame and a second head cage frame, wherein the first head cage frame and the second head cage frame are arc-shaped grid plates; the inner side edge of the first head cage frame and the inner side edge of the second head cage frame are connected with a longitudinal slat through hinges; the outer side edge of the first head cage frame and the outer side edge of the second head cage frame are connected through clips; a first head porous inflatable cushion is arranged on the arc-shaped inner side of the first head cage frame; a second head porous inflatable cushion is arranged on the arc-shaped inner side of the second head cage frame; and a neck porous inflatable cushion is arranged in the U-shaped frame plate. The fixing device disclosed by the invention is simple in structure, easy to operate and convenient and accurate in fixing head, and is suitable for accurate and effective operation of magnetic resonance imaging-guided focused ultrasound for diagnosing and treating the encephalopathy in a long time.

Description

technical field [0001] The invention relates to the fields of clinical diagnosis and treatment of brain diseases and related medical devices, and in particular to a fixation device for magnetic resonance imaging-guided focused ultrasound diagnosis and treatment of brain diseases. Background technique [0002] Using the thermal effect generated by ultrasonic focusing inside the human body, thermal ablation can be performed on diseased tissues (such as tumors) inside the human body. With the rapid development and progress of science and technology, it is becoming a clinical non-invasive treatment method and technology. . For example, the clinical medical instrument ExAblateNeurotcMRgFUS (transcranial magnetic resonance imaging-guided focused ultrasound, transcranial magnetic resonance imaging-guided focused ultrasound) launched by InSightec, headquartered in Haifa, Israel, uses high-energy multi-phase control probes and multi-channel drive electronics to accurately transmit ul...
