Transcranial magnetic stimulator system of control stimulation coil end

Abstract

The invention provides a transcranial magnetic stimulator system of a control stimulation coil end. The transcranial magnetic stimulator system comprises a magnetic stimulation module, a control module, a remote regulating module, a remote display module, a signal input module, a motion threshold determination module, and a signal induction module. The motion threshold of a stimulated person can be measured just by one operator. Thus, the transcranial magnetic stimulator system greatly saves manpower, prevents faults possibly generated by cooperative work of multiple people, automatically determines the motion threshold, simplifies a workflow, increases measurement efficiency and measurement speed, improves accuracy of magnetic stimulation effectiveness judgment, and reduces a misjudgment probability of artificial judgment.

Description

technical field [0001] The invention relates to a control technology of a transcranial magnetic stimulator, in particular to a transcranial magnetic stimulator system and a method for measuring a motion threshold, belonging to the technical field of medical devices. Background technique [0002] Transcranial Magnetic Stimulation (TMS) technology is a technology that uses alternating pulsed magnetic fields to act on the central nervous system (mainly the brain), changing the membrane potential of cortical nerve cells, causing them to generate induced currents, affecting brain metabolism and neurological effects. Magnetic stimulation technology that induces a series of physiological and biochemical reactions through electrical activity. Because of its painless and non-invasive physical characteristics, it can assist in the exploration of brain function and advanced cognitive functions. Together with PET, fMRI, and MEG, it is called "the four brain science and technology in the...

Problems solved by technology

[0007] The existing transcranial magnetic stimulation equipment has the following problems in measuring the motor threshold: since the motor threshold measurement generally uses a stimulating coil to stimulate the motor center of the cerebral cortex in a single stimulation, the operator needs to take into account the position of the coil on the scalp and the Stimulus intensity

However, due to individual differences, the location of the stimulated skull surface and the intracranial cortex often cannot be accurately corresponded to. At the same time, the existing magnetic stimulation equipment has a large coil, and the focusing effect of the magnetic field is difficult to determine the exact correspondence between the stimulation point and the intracranial cerebral cortex. However, the switch of the existing magnetic stimulation equipment to trigger magnetic stimulation is generally on the host computer. In order to continuously change the stimulation intensity at the same head position of the stimulated person to find the minimum stimulation intensity (motor threshold), two operators are generally required. One of the operators holds the coil with one hand to stimulate the stimulated person's head, presses the stimulated person's head with the other hand for positioning, and the second operator adjusts the stimulation intensity on the host of the magnetic stimulation device and Record the intensity information, and two operators cooperate to adjust the stimulation position and stimulation intensity many times to find the minimum stimulation intensity MT (motor threshold). Collaborative work is also prone to errors

[0008] Utility model patent ZL200820190281.1 discloses a magnetic field stimulator stimulation pad, which is the closest prior art to the present invention (authorized announcement number: CN201324444Y), by designing a trigger button and a display screen on the handle to control the magnetic stimulation , but the stimulation beat has the following defects: First, although it has a trigger button on the handle, it can only be used to trigger stimulation (such as a single magnetic stimulation), and cannot be used to adjust the stimulation intensity. If you want to adjust the stimulation Intensity still requires an operator to be on the mainframe, in other words, it still requires two operators to work together

Second, when using the above-mentioned stimulation shots, the operator needs to manually identify the effectiveness of the stimulation, which is very easy to cause misjudgment, and relies on experience and memory to judge whether the current stimulation intensity is the minimum stimulation intensity MT. The operation process is not only cumbersome and complicated, but also easy. An error occurred
