Description

Technical Field

[0001] This invention belongs to the technical field of transcranial magnetic stimulation equipment, specifically relating to a posture-adjustable transcranial magnetic stimulation device and its working method. Background Technology

[0002] Transcranial magnetic stimulation (TMS) is an instrument used in the field of clinical medicine. It acts on the cerebral cortex to generate induced currents, thereby changing the action potential of cortical nerve cells. The magnetic signal can pass through the skull without attenuation to stimulate the cerebral cortex and peripheral nerves, and purposefully and precisely regulate the power of neurotransmitters to produce excitation or inhibition, thereby affecting brain metabolism and neural electrical activity.

[0003] Transcranial magnetic stimulation (TMS), transcranial electrical stimulation (TES), and transcranial ultrasound stimulation (TUS) are techniques used in the medical rehabilitation field to stimulate and treat transcranial nerves. Current TMS devices require the following steps for each treatment: identifying the target point, determining the placement of the stimulation probe, and setting the treatment parameters. During treatment, the position of the stimulation probe is fixed; any movement of the patient's head will cause deviation from the treatment target.

[0004] The attitude sensor is a high-performance 3D motion attitude measurement system based on MEMS technology. It includes a three-axis gyroscope, a three-axis accelerometer, and a three-axis electronic compass motion sensor. Through an embedded low-power ARM processor, it obtains temperature-compensated 3D attitude and orientation data. Utilizing quaternion-based 3D algorithms and special data fusion technology, it outputs zero-drift 3D attitude and orientation data in real-time, expressed in quaternions and Euler angles. The LPMS series and iAHRS-M0 attitude sensors can be widely embedded in model aircraft, drones, robots, mechanical gimbals, vehicles, ships, ground and underwater equipment, virtual reality, and human motion analysis products and equipment requiring autonomous 3D attitude and orientation measurement.

[0005] The shortcomings of the current technology are that the current transcranial navigation system requires calibration every time it is turned on. Whether it is the same patient or a different patient, the navigation system needs to be re-aligned whenever the treatment is restarted, which is inefficient. Moreover, the patient's head is not allowed to move during the treatment. Even coughing or sneezing will affect the positioning accuracy and thus cause deviations in the treatment effect. Summary of the Invention

[0006] The purpose of this invention is to address the problems existing in the prior art by providing a posture-adjustable transcranial magnetic stimulation device and its working method, which has the advantages of high treatment efficiency, high treatment accuracy, and high comfort.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a posture-adjustable transcranial magnetic stimulation device, comprising a support and a headgear. The top of the support is provided with a mounting portion, and the mounting portion is provided with a posture adjustment mechanism. The posture adjustment mechanism is connected to a stimulation probe. The posture adjustment mechanism includes several telescopic adjustment components, which are movably connected to the outer ring of the stimulation probe. The stimulation probe is provided with a probe posture sensor, and the bottom of the stimulation probe is provided with a flexible locking buckle. The headgear is provided with several connecting portions for detachable connection to the bottom end of the flexible locking buckle. The bottom end of the flexible locking buckle is provided with a headgear posture sensor. The headgear posture sensor, the probe posture sensor, and the posture adjustment mechanism are all electrically connected to a controller.

[0008] In the above solution, the posture adjustment mechanism is positioned by the mounting part at the top of the bracket. The telescopic adjustment component of the posture adjustment mechanism adjusts the angle of the stimulation probe by telescopic movement, so that the stimulation probe is directly facing the target area of ​​the head. The relative position of the stimulation probe and the headgear is detected in real time by the probe posture sensor and the headgear posture sensor. When the head moves the headgear angle, the controller controls the telescopic adjustment component to adjust the angle of the stimulation probe accordingly. Several connecting parts are set on the headgear, corresponding to different stimulation areas, which can be used to quickly locate the stimulation probe treatment area during each treatment. The maximum distance between the stimulation probe and the headgear connecting parts is limited by a flexible buckle to ensure the stimulation effect. The posture adjustment mechanism positions the stimulation probe and reduces pressure on the head.

[0009] Furthermore, the mounting part includes a planar moving mechanism, which comprises two mutually perpendicular linear moving modules.

[0010] The position of the posture adjustment mechanism is adjusted by two linear movement modules of the planar movement mechanism, thereby increasing the adjustment range of the stimulation probe and ensuring that the position of the stimulation probe and the head cover remain in correspondence.

[0011] Furthermore, the connecting part includes a positioning hole groove formed on the headgear, and the bottom of the flexible buckle is detachably connected to a buckle body, which is connected to the positioning hole groove.

[0012] The buckle is fixed to the headgear by making positioning holes and slots on the headgear to facilitate the buckle body to pass through, and the buckle body is engaged with the bottom of the flexible buckle.

[0013] Furthermore, the support frame includes a support rod and a base, the base of which is connected to a recliner.

[0014] The support rod is positioned by the base to ensure the stability of the stimulation probe. During transcranial magnetic stimulation, the patient lies on a recliner to receive treatment, improving the comfort of the treatment.

[0015] Furthermore, the probe posture sensor and the flexible latch are both connected to the center of the bottom surface of the stimulation probe.

[0016] The probe posture sensor is located at the center of the stimulation probe, which facilitates the detection of overall posture changes of the stimulation probe. The flexible buckle connects the center of the stimulation probe to the treatment position of the headgear to ensure the treatment effect.

[0017] Furthermore, the top surface of the stimulation probe is provided with several ball joints at equal intervals, and the ball joints are connected to the telescopic adjustment components.

[0018] By setting several ball joints, the angle of the stimulation probe can be adjusted when the telescopic adjustment component extends or retracts.

[0019] Furthermore, the attitude adjustment mechanism includes a housing, and the telescopic adjustment component includes a hydraulic telescopic rod.

[0020] The outer shell is used to connect and position the telescopic adjustment rod, which can extend and retract to adjust the angle of the stimulation probe.

[0021] Furthermore, the headgear includes a cover and a chin strap located at the lower part of the cover.

[0022] The cover is designed to be worn over the head. A chin strap is provided at the bottom of the cover to facilitate wearing and ensure the stability of the connection between the cover and the head, thereby improving the precision of treatment.

[0023] A method for operating the aforementioned posture-adjustable transcranial magnetic stimulation device includes the following steps: after initially determining the position of the treatment target point, first connect the flexible buckle at the bottom of the stimulation probe to the corresponding connecting part on the headgear, then align the position of the stimulation probe, and after the controller records the initial posture of the probe posture sensor and the headgear posture sensor, transcranial magnetic stimulation can be performed. During the treatment, the headgear posture sensor detects the headgear orientation in real time and transmits the orientation information to the controller. When the headgear orientation changes, the controller controls the posture adjustment mechanism to make the positions of the probe posture sensor and the headgear posture sensor correspond.

[0024] In the above scheme, after the initial determination of the target point, the flexible buckle is connected to the headgear connection to ensure the relative position of the stimulation probe and the treatment area. The stimulation probe is then aligned so that it faces the treatment target point. The controller records the initial posture angle and distance between the probe posture sensor and the headgear posture sensor. When the head moves during treatment, the controller adjusts the posture adjustment mechanism accordingly to adjust the posture of the stimulation probe, maintain the relative position of the stimulation probe and the treatment target point, and improve the treatment effect.

[0025] Furthermore, the headgear is divided into several treatment areas, and the position of the connecting part corresponds to the treatment area. After the initial determination of the treatment target position, the corresponding treatment area position is recorded, and transcranial magnetic stimulation is directly applied to the treatment area when subsequent treatment begins.

[0026] By dividing the treatment area on the headgear and corresponding the connection position, the positioning process of the stimulation probe is simplified, eliminating the need to test the target position every time, which facilitates the positioning of the stimulation probe and improves treatment efficiency.

[0027] Furthermore, during the initial treatment, the controller stores the initial alignment of the stimulation probe, the sensitive points of the treatment area, the instrument parameters, and the patient information. Subsequent treatments will directly retrieve the archived data to complete the treatment configuration.

[0028] The controller matches and archives treatment parameters and patient information, facilitating subsequent treatment. It can directly read and configure the data, improving treatment efficiency.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. By connecting a headgear posture sensor to the headgear and wearing it on the head, the posture sensor detects the relative position of the stimulation probe and the headgear in real time during the treatment. In conjunction with the posture adjustment mechanism, the position of the stimulation probe is adjusted accordingly as the head moves, ensuring the accuracy of the treatment area and improving the treatment precision and effect.

[0031] 2. The headgear of this device will subdivide and calibrate the stimulation area. Once the treatment plan is formulated, the corresponding treatment data will be stored and archived, such as the initial alignment of the stimulation probe, the treatment area, and the patient's information. After the current treatment is completed, when the same patient undergoes the same course of consolidation treatment, the archived data can be retrieved to complete the treatment configuration in one step. There is no need to re-measure the head treatment target points, which is convenient and quick, improves treatment efficiency, and saves the operation matching time for doctors and patients.

[0032] 3. By setting up a support bracket to support the stimulation probe, pressure on the head is reduced. The posture of the stimulation probe can be adjusted by a posture adjustment mechanism, which relaxes the treatment conditions, reduces restrictions on the head, is more patient-friendly, and improves treatment comfort and efficacy.

They are only for the convenience of describing the present invention or simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed or operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0037] Example 1

[0038] like Figure 1-2 As shown, a posture-adjustable transcranial magnetic stimulation device includes a support and a headgear. The top of the support is provided with a mounting part, and the mounting part is provided with a posture adjustment mechanism. The posture adjustment mechanism is connected to a stimulation probe 4. The posture adjustment mechanism includes several telescopic adjustment components, which are movably connected to the outer ring of the stimulation probe 4. The stimulation probe 4 is provided with a probe posture sensor 7, and the bottom of the stimulation probe 4 is provided with a flexible buckle. The headgear is provided with several connecting parts for detachable connection with the bottom end of the flexible buckle. The bottom end of the flexible buckle is provided with a headgear posture sensor 10. The headgear posture sensor 10, the probe posture sensor 7, and the posture adjustment mechanism are all electrically connected to a controller.

[0039] In the above scheme, the posture adjustment mechanism is positioned by the mounting part at the top of the bracket. The telescopic adjustment component of the posture adjustment mechanism drives the stimulation probe 4 to adjust its angle by telescopic movement, so that the stimulation probe 4 is directly facing the target area of ​​the head stimulation. The relative position of the stimulation probe 4 and the headgear is detected in real time by the probe posture sensor 7 and the headgear posture sensor 10. When the head moves the headgear angle, the controller controls the telescopic adjustment component to adjust the angle of the stimulation probe 4 accordingly. Several connecting parts are set on the headgear, corresponding to different stimulation areas, which can be used to quickly locate the treatment area of ​​the stimulation probe 4 during each treatment. The maximum distance between the stimulation probe 4 and the headgear connecting parts is limited by a flexible buckle to ensure the stimulation effect. The posture adjustment mechanism positions the stimulation probe 4, reducing pressure on the head.

[0040] After initially determining the positions of the stimulation probe 4 and the head, the posture angles of the stimulation probe 4 and the head are recorded. If the head posture changes, the stimulation probe 4 will also change accordingly. The stimulation probe 4 and the headgear are weakly connected by a buckle, which will cause the patient to feel a slight pull, preventing excessive distance between the head and the stimulation probe 4. The weight of the stimulation probe 4 is supported by the support structure, thus avoiding pressure on the patient. Furthermore, after incorporating precise subdivision and localization of the skull, a data storage and archiving function has been added. When the same patient undergoes the same course of consolidation treatment, the archived data can be retrieved, completing the treatment configuration in one step.

[0041] Furthermore, the mounting part includes a planar moving mechanism, which comprises two mutually perpendicular linear moving modules 11.

[0042] The position of the posture adjustment mechanism is adjusted by two linear movement modules 11 of the planar movement mechanism, thereby increasing the adjustment range of the stimulation probe 4 and ensuring that the position of the stimulation probe 4 and the head cover remain in correspondence.

[0043] The mounting section includes a metal ring 12 mounted on the top of the bracket. A horizontal linear motion module 11 is mounted on the metal ring 12. The linear motion module 11 includes a U-shaped base 1 and a U-shaped base 2 slidably mounted on the U-shaped base 1. The U-shaped base 1 is equipped with a motor and a lead screw, which is screwed to the U-shaped base 2. An attitude adjustment mechanism is slidably connected to the U-shaped base 2, which is also equipped with a motor and a lead screw, which is screwed to the attitude adjustment mechanism. The U-shaped base 1 and the U-shaped base 2 are perpendicular to each other, thereby realizing the surface position adjustment of the attitude adjustment mechanism.

[0044] In some embodiments, the planar movement mechanism is omitted, and the posture adjustment mechanism is directly fixedly connected to the top of the support. The angle of the stimulation probe 4 is adjusted by the posture adjustment mechanism so that the stimulation probe 4 is directly facing the treatment target to ensure the treatment effect.

[0045] Furthermore, the connecting part includes a positioning hole groove 9 formed on the headgear, and the bottom of the flexible buckle is detachably connected to a buckle body 13, which is connected to the positioning hole groove 9.

[0046] The buckle 13 is made easy to pass through by opening a positioning hole groove 9 on the headgear. The buckle 13 is engaged with the bottom of the flexible buckle to fix the flexible buckle to the headgear.

[0047] The flexible buckle includes a bottom latching part 8 and an upper flexible part 16. The flexible part 16 can be made of rubber or fiber. The latching part 8 is used to engage with the buckle body 13. The headgear posture sensor 10 is connected to the bottom surface of the latching part 8 and is pressed against the headgear under the action of the buckle body 13. Optionally, the bottom end of the flexible buckle can also be directly engaged with the positioning hole groove 9 by means of a latch.

[0048] Furthermore, the support frame includes a support rod 1 and a base 2, with the base 2 connected to a recliner.

[0049] The base 2 positions the support rod 1 to ensure the stability of the support for the stimulation probe 4. During transcranial magnetic stimulation, the patient lies on a recliner to receive treatment, improving the comfort of the treatment.

[0050] Furthermore, the probe posture sensor 7 and the flexible latch are both connected to the center of the bottom surface of the stimulation probe 4.

[0051] The probe posture sensor 7 is located at the center of the stimulation probe 4, which facilitates the detection of the overall posture changes of the stimulation probe 4. The flexible buckle connects the center of the stimulation probe 4 to the treatment position of the headgear to ensure the treatment effect.

[0052] The probe posture sensor 7 and the flexible locking buckle can be connected to the stimulation probe 4 by snap-fit ​​connection, screw connection or adhesive connection.

[0053] Furthermore, the top surface of the stimulation probe 4 is provided with several ball joints 14 at equal intervals, and the ball joints 14 are connected to the telescopic adjustment member accordingly.

[0054] By setting several ball joints 14, the angle of the stimulation probe 4 can be adjusted when the telescopic adjustment member extends or retracts.

[0055] Three ball joints 14 are arranged along the outer ring of the stimulation probe 4.

[0056] Furthermore, the attitude adjustment mechanism includes a housing 5, and the telescopic adjustment component includes a hydraulic telescopic rod 6.

[0057] The outer shell 5 is used to connect and position the telescopic adjustment rod, and the hydraulic telescopic rod 6 can extend and retract to adjust the angle of the stimulation probe 4.

[0058] The outer casing 5 slides into the U-shaped seat 2 and positions the hydraulic telescopic rod 6. A telescopic motor can also be used for the telescopic adjustment mechanism.

[0059] Furthermore, the headgear includes a cover body 3 and a chin strap 15 located at the lower part of the cover body 3.

[0060] The cover 3 is used to be put on the head. The lower part of the cover 3 is provided with a chin strap 15 to facilitate the wearing of the head, ensure the stability of the connection between the head cover and the head, and improve the treatment accuracy.

[0061] A method for operating the aforementioned posture-adjustable transcranial magnetic stimulation device includes the following steps: after initially determining the position of the treatment target point, the flexible buckle at the bottom of the stimulation probe 4 is connected to the corresponding connecting part on the headgear. After the stimulation probe 4 is aligned, the controller records the initial posture of the probe posture sensor and the headgear posture sensor, and then transcranial magnetic stimulation can be performed. During the treatment, the headgear posture sensor detects the headgear orientation in real time and transmits the orientation information to the controller. When the headgear orientation changes, the controller controls the posture adjustment mechanism to make the probe posture sensor 7 correspond to the headgear posture sensor.

[0062] In the above scheme, after the initial determination of the target point, the flexible buckle is connected to the headgear connection to ensure the relative position of the stimulation probe 4 and the treatment area. The person puts on the headgear and straightens the stimulation probe 4 so that it faces the treatment target point. The controller records the initial posture angle and distance between the probe posture sensor and the headgear posture sensor. When the head moves during the treatment, the controller adjusts the posture adjustment mechanism accordingly to adjust the posture of the stimulation probe 4, maintain the relative position of the stimulation probe 4 and the treatment target point, and improve the treatment effect.

[0063] Furthermore, the headgear is divided into several treatment areas, and the position of the connecting part corresponds to the treatment area. After the initial determination of the treatment target position, the corresponding treatment area position is recorded, and transcranial magnetic stimulation is directly applied to the treatment area when subsequent treatment begins.

[0064] By dividing the treatment area on the headgear and corresponding the location of the connecting part, the positioning process of the stimulation probe 4 is simplified, eliminating the need to test the target point location every time, which facilitates the positioning of the stimulation probe 4 and improves treatment efficiency.

[0065] Furthermore, during the initial treatment, the controller stores the initial alignment of the stimulation probe 4, the sensitive points of the treatment area, the instrument parameters, and the patient information. Subsequent treatments will directly retrieve the archived data to complete the treatment configuration.

[0066] The controller matches and archives treatment parameters and patient information, facilitating subsequent treatment. It can directly read and configure the data, improving treatment efficiency.

[0067] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
