In this embodiment, the electroencephalogram acquisition interface 108 includes twelve acquisition interface units, the brain deep electrode interface 109 includes twelve electrode interface units, the switch switching array 106 includes twelve relay groups 1061, each relay group 1061 includes eighteen relays, and each brain deep electrode 3 includes eighteen conductive electrode points.
Of the twelve relay groups 1061, each relay group 1061 is electrically connected to one of the collection interface units and one of the electrode interface units, respectively.
When the deep brain electrode 3 is connected with the electrode interface unit, the electrode identification module 107 connected with the switch switching array 106 can identify that eighteen conductive electrode points are included in one deep brain electrode 3, and the eighteen conductive electrode points are in one-to-one correspondence with eighteen relays in the relay group 1061.
When the plurality of brain deep electrodes are connected to the plurality of relay groups 1061 via the electrode interface unit, the number of the plurality of brain deep electrodes 3 connected to the plurality of relay groups 1061 and the number of the conductive electrode points included in each brain deep electrode 3 are recognized by the electrode recognition module 107, and the number of connections of the brain deep electrodes 3 and the number of the conductive electrode points included in each brain deep electrode 3 are input to the MCUa 101. The MCUa101 selects the relays of the same number from the relay group 1061 according to the number of the conductive electrode points in each deep brain electrode 3, and matches the conductive electrode points with the relays, so that the conductive electrode points can form a corresponding relationship with the relays.

The brain electrical information of the patient is acquired through the brain electrical acquisition equipment connected with the acquisition interface unit, and the brain deep electrodes 3 connected with the twelve electrode interface units can know which brain deep electrodes 3 have the conductive electrode points closer to the selected brain tissue region. One or more conductive electrode points near the selected brain tissue region are selected in the display interface of the human-computer interface unit a102, and the selected conductive electrode points are switched to be connected with the radio frequency and electrical stimulation input interface 105, so that radio frequency current or electrical stimulation current is output to the selected brain tissue region according to the treatment requirement, and related treatment operation is completed.
Wherein MCUa101 controls whether a selected conductive electrode point is switched to connect with radio frequency and electrical stimulation input interface 105 by controlling the on-off state of a relay corresponding to the selected conductive electrode point. When the MCUa101 controls the relay to be in a normally open state, the selected conductive electrode point is not connected with the radio frequency and electrical stimulation input interface 105, so that the selected conductive electrode point can perform electroencephalogram acquisition operation as required. When the MCUa101 controls the relay in the closed state, the selected conductive electrode point is switched to connect with the radio frequency and electrical stimulation input interface 105, and thus is switched by the electroencephalogram acquisition operation to perform an electrical stimulation operation or a radio frequency ablation operation.

When the switching operation is performed, an operator only needs to set in the display interface of the man-machine interface unit a102, so that the switching of the working state of the selected conductive electrode point can be completed, and the selected conductive electrode point can be switched to output electric stimulation current or output radio frequency current by the current electroencephalogram acquisition operation. In the switching process, the deep brain electrode 3 is always connected with the switch array 106, so that the deep brain electrode is not required to be separated from the switch array 106, a great amount of time is saved, and meanwhile, the accuracy is ensured.
The number of deep brain electrodes 3 electrically connected to the change-over switch array 106 and the number of conductive electrode points on the deep brain electrodes 3 can be identified by the electrode identification module 107 added to the electrode transfer control device 1. Meanwhile, the identified connection number of the deep brain electrodes 3 and the number of the conductive electrode points on the deep brain electrodes 3 can be displayed in a display interface of the human-computer interface unit a102 through the MCUa101, so that an operator can visually check the connection number of the deep brain electrodes 3 and the number of the conductive electrode points on the deep brain electrodes 3.

s1, assembling a plurality of needed brain deep electrodes on a brain deep electrode interface of the electrode switching control device, and displaying the connection quantity of the brain deep electrodes and the quantity of conductive electrode points in each brain deep electrode in a display interface of a human-computer interface unit a.
In step S1, after the brain deep electrodes are connected to the relay groups via the electrode interface units, the number of the plurality of brain deep electrodes connected to the plurality of relay groups and the number of the conductive electrode points included in each brain deep electrode are recognized by the electrode recognition module, and the number of the connection of the brain deep electrodes and the number of the conductive electrode points included in each brain deep electrode are input into the MCUa.
The MCUa selects relays with the same quantity from the relay group according to the quantity of the conductive electrode points in each deep brain electrode, and matches the conductive electrode points with the relays, so that the conductive electrode points can form a corresponding relation with the relays.
The MCUa displays the number of connections of the brain deep electrodes, the number of conductive electrode points in each brain deep electrode, and the correspondence between the conductive electrode points in each brain deep electrode and the relay in the display interface of the human-computer interface unit a.
S2, selecting at least one conductive electrode point close to the selected brain tissue area according to the brain electrical information and the brain deep electrode distribution diagram, and setting the selected conductive electrode point in a display interface of the human-computer interface unit a so as to switch the selected conductive electrode point into electrical connection with the input interface.
In step S2, two conductive electrode points on the same deep brain electrode or any two conductive electrode points on a plurality of deep brain electrodes may be selected according to the location of the selected brain tissue region. After the selected conductive electrode point is set in the display interface of the human-machine interface unit a, the selected conductive electrode point is switched to be electrically connected with the radio frequency and electrical stimulation input interface through the MCUa.
Wherein the MCUa controls whether the selected conductive electrode point is switched to connect with the radio frequency and electrical stimulation input interface by controlling the on-off state of the relay corresponding to the selected conductive electrode point. When the MCUa control relay is in a normally open state, the selected conductive electrode point is not connected with the radio frequency and electric stimulation input interface, so that the selected conductive electrode point can perform electroencephalogram acquisition operation according to requirements. When the MCUa control relay is in a closed state, the selected conductive electrode point is switched to be connected with the radio frequency and electrical stimulation input interface, so that the electroencephalogram acquisition operation is switched to perform the electrical stimulation operation or the radio frequency ablation operation.
S3, the radio frequency generating component or the electric stimulation generating component sequentially passes through the output interface, the radio frequency and electric stimulation input interface and the selected conductive electrode point to act the generated radio frequency current or the generated electric stimulation current on the selected brain tissue area.
In step S3, according to the requirements of the selected brain tissue region, the output interface is controlled by the change-over switch to output radio frequency current or electric stimulation current.
When the change-over switch is adjusted to a position for outputting radio-frequency current, the MCUb controls the radio-frequency generation module to generate radio-frequency current, and the radio-frequency current sequentially passes through the output interface, the radio-frequency and electric stimulation input interface and the selected conductive electrode point to be acted on the selected brain tissue region.
When the change-over switch is adjusted to a position for outputting the electric stimulation current, the MCUb controls the electric stimulation generating module to generate the electric stimulation current, and the electric stimulation current sequentially passes through the output interface, the radio frequency and electric stimulation input interface and the selected conductive electrode point to be acted on the selected brain tissue region.
When radio frequency ablation is carried out on a selected brain tissue region through the conductive electrode point, the temperature and impedance conditions of the tissue in the selected brain tissue region can be acquired in real time through the temperature measuring module and the impedance measuring module, so that the output power of radio frequency current is dynamically adjusted according to the temperature and the impedance conditions of the tissue. In addition, the radio frequency power is monitored in real time through the radio frequency measurement module, and after the radio frequency power is fed back to the MCUb, the MCUb can analyze and adjust the radio frequency power.
When the selected brain tissue region is electrically stimulated through the conductive electrode point, the electrical stimulation parameters are monitored in real time through the electrical stimulation measuring module, and after the electrical stimulation parameters are fed back to the MCUb, the MCUb can analyze and adjust the electrical stimulation parameters.

It will be appreciated by persons skilled in the art that many variations, modifications, and even equivalents may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
