Description

A kind of efficient TMS resetting method
Technical field
The present invention relates to TMS treatment technology fields, and in particular to a kind of efficient TMS resetting method.
Background technique
TMS technology is that the widely applied a kind of physics in mental rehabilitation and neuromodulation field is examined in worldwide at present Treatment technology generates pulsed magnetic field using conductive coil, to treat to patient.Traditional TMS therapeutic modality generally includes Following steps: operator finds therapy target region (positioning by rule of thumb) in patients head;TMS coil is placed on the region, Guarantee that hub of a spool face target spot, coil plane are tangent with scalp;TMS coil is gripped using mechanical device;Starting TMS starts to treat.
Since TMS treatment usually requires for a long time, by course of therapy, the target purely positioned by experience and the mode of memory Point not can guarantee the accuracy treated every time.The all different target position of patient per's treatment is common situation, and due to The lesser reason of fading characteristic and Effective target site region in magnetic field, if it cannot be guaranteed that the target spot accuracy for the treatment of, TMS treatment Curative effect will have a greatly reduced quality.It is precisely necessary for thus finding a kind of method guarantee target spot.
, worldwide there are some researchs in the problem of TMS accurate resetting, but other methods are base mostly at present In the infrared positioning mode of guide-lighting ball.Dedicated guide-lighting ball must be all worn when this method positions every time to patient and TMS coil, according to Relative position of the guide-lighting ball in infrared shooting device is positioned.Because the position worn every time is all not fixed, also It needs additionally to determine the relative position of guide-lighting ball and the number of people by complicated positioning using a kind of dedicated pen with means for holding it in right position, therefore grasps Work gets up to be inconvenient, and inefficiency, uses in the infrared positioning mode based on guide-lighting ball at present, for wearing and positioning leaded light The time of ball is about 30 minutes/people, since a TMS treatment also only needs 10-20 minutes, current this localization method It is not suitable for the efficient resetting of TMS.
The Chinese patent of application number 2017207206945 discloses a kind of transcranial magnetic stimulation treatment equipment, including TMS line Circle, bracket, mechanical arm, controller and positioning device, positioning device can detect the accurate location of human body head, to control TMS coil is precisely located to human body head mechanical arm, reduces manual operation, but obtains the disadvantage is that relying only on filming apparatus The position of patients head and TMS coil are taken, the accuracy of resetting is lower, not can guarantee the accuracy treated every time.
Therefore, it is badly in need of providing a kind of efficient TMS resetting method, was not only positioned without wearing guide-lighting ball, but also can guarantee Target spot is accurate when treating every time.
