Description

Technical Field

[0001] This invention relates to the field of therapeutic device technology, and in particular to an ultrasound therapeutic device based on multimodal magnetic resonance guidance and a method for treating depression. Background Technology

[0002] Depression is a common mood disorder characterized by persistent low mood and loss of interest, accompanied by sleep disturbances, decreased attention, and self-denial. Its causes involve neurotransmitter imbalance, genetic and psychosocial factors, which seriously affect social and occupational functioning and quality of life. Some patients do not respond well to traditional drugs or psychotherapy, so it is necessary to explore new intervention methods.

[0003] Low-intensity transcranial focused ultrasound (LCI) is a non-invasive neuromodulation technique that uses focused ultrasound to precisely target brain regions associated with depression (such as the dorsolateral prefrontal cortex) to regulate neuronal activity. It has the advantages of strong targeting, good penetration, and high safety, and can be used as a supplementary or alternative treatment to provide personalized and precise treatment options for patients with depression, helping to improve symptoms and promote recovery.

[0004] An existing patent (publication number: CN110732096B) discloses a head fixation device and a magnetic resonance-guided ultrasound therapy device, including a bed frame, a frame fixation plate, a positioning support rod, and a locking rod. The frame fixation plate is vertically adjustable on the bed frame, and the positioning support rod and the locking rod are respectively disposed on the frame fixation plate. A positioning notch and a locking slot are provided on the fixed frame.

[0005] Although the application can quickly adjust along the patient's height and along the rotational radial direction of the fixed frame through multiple adjustable rods and positioning pins, making it easy for the head fixation device to quickly fix the head of patients with different head shapes, the contact method between the fixation device and the patient's head is point contact, with a small contact area, which makes it relatively uncomfortable for the patient to wear.

[0006] In addition, the aforementioned application's thread is not properly stored, and the wire is too long, making it inconvenient to organize. When treating users, the thread is prone to tangling and knotting, affecting the safety of the treatment operation. Summary of the Invention

[0007] The purpose of this invention is to provide a multimodal magnetic resonance-guided ultrasound therapy device and a method for treating depression, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a multimodal magnetic resonance-guided ultrasound therapy device, comprising a therapy device and an adjustment component, wherein the adjustment component is disposed on the therapy device, the adjustment component includes an elastic fastening band, the elastic fastening band being movably disposed inside the therapy device, and a fixing ring being disposed at one end of the elastic fastening band located outside the therapy device, the fixing ring having a cross hole, the adjustment component further includes a cross fixing post, the cross fixing post being disposed on a wire winding component, and a wire winding component, the wire winding component being disposed on the therapy device, the wire winding component including a first housing and a second housing, a connecting post being fixed on the first housing, the first housing being fixed on the therapy device, a limiting member being disposed on the connecting post, the limiting member being disposed of a coil spring and a wire, the wire extending to the outside of the first housing and the second housing.

[0009] Preferably, the treatment device includes a strap with a head-mounted protective shell mounted on it. A trigger is installed inside the head-mounted protective shell, and wires connect the triggers to each other. The wires are connected to a cable body. The strap and the head-mounted protective shell are detachably connected. The trigger is embedded inside the head-mounted protective shell, and both ends of the wires are connected to the trigger and the cable body, respectively. The strap is made of medical-grade elastic nylon, and the head-mounted protective shell is made of ABS engineering plastic. The strap uses elastic contraction to securely fix the head-mounted protective shell on the head, preventing displacement during treatment. The head-mounted protective shell provides protection and a mounting carrier for the trigger, isolating it from external interference. The trigger, as the core component for ultrasound emission, outputs low-intensity focused ultrasound through signals transmitted via the wires, acting on brain regions related to depression.

[0010] Preferably, the adjustment component further includes a guide block, which is fixed to the outside of the headband protective shell. The elastic fastening strap is slidably connected inside the guide block. The guide block is fixed to the outer wall of the headband protective shell by screws, and the elastic fastening strap slides against the inner wall of the guide block with a clearance fit. The guide block provides guidance and limitation for the elastic fastening strap. The elastic fastening strap adjusts its length and width by sliding within the guide block, adapting to users with different head shapes, increasing the contact area with the head, and improving wearing comfort.

[0011] Preferably, the adjustment component further includes elastic straps and fixing members. Multiple elastic straps are provided and evenly distributed inside the head-mounted protective shell. An elastic fastening band is disposed on the elastic straps. The fixing member is fixed inside the head-mounted protective shell, and the fixing member is fixed to one end of the elastic fastening band located inside the head-mounted protective shell. The elastic straps are fixed to the inner wall of the head-mounted protective shell, and the elastic fastening band and elastic straps are nested together. The elastic straps are used to maintain the shape of the elastic fastening band within the head-mounted protective shell. When the elastic fastening band contracts, the elastic straps can deform, and the elastic straps move with the elastic fastening bands.

[0012] Preferably, the wire winding component further includes a circular guide groove and a rectangular guide groove, both of which are formed on the second housing. The circular guide groove and the rectangular guide groove are connected, and the housing is disposed in the circular guide groove. The circular guide groove can guide and position the housing, while the rectangular guide groove is used to guide the steel ball, allowing the steel ball to move within the rectangular guide groove.

[0013] Preferably, the device further includes a cleaning component, which is disposed on the yarn winding component. The cleaning component includes a clamping plate, a cleaning block, and a yarn passage hole. The clamping plate is snapped onto the first housing and the second housing, and the cleaning block is snapped onto the clamping plate. The yarn passage hole is formed on the cleaning block. The clamping plate is detachably connected to the first housing and the second housing by a snap-fit ​​mechanism. The cleaning block is wrapped with a soft material. When the yarn is pulled, the cleaning block can clean the yarn. The clamping plate and the cleaning block can be removed for cleaning, thereby maintaining a good cleaning effect and preventing dirt from affecting the yarn.

[0014] Preferably, the limiting component includes a housing with a through hole, a first limiting part, and a second limiting part. A second guide groove, a third guide groove, and a first guide groove are formed from the inside out between the housing, the first limiting part, and the second limiting part. The limiting component also includes a steel ball movably disposed within the second guide groove, the third guide groove, the first guide groove, and the rectangular guide groove. The cross-shaped fixing post is fixed to the housing. The first and second limiting parts are integrally formed with the housing. The steel ball and the second, third, first, and rectangular guide grooves are in rolling contact. The steel ball is made of wear-resistant stainless steel. The second, third, and first guide grooves provide rolling tracks for the steel ball. The rolling of the steel ball reduces the frictional resistance when the housing rotates, making the winding of the thread smoother. Rotating the housing drives the cross-shaped fixing post to rotate synchronously, thereby pulling the fixing ring and the elastic fastening band to wind up, achieving the fit between the elastic fastening band and the head.

[0015] The present invention also provides a method for treating depression, comprising the following steps:

[0016] S1: Wear the head-mounted protective case on the user's head and restrain the position of the head-mounted protective case with straps;

[0017] S2: Pull out the cable and connect it to the power supply to put the trigger in standby mode;

[0018] S3: Before treating the user, fasten the fixation ring onto the cross-shaped fixation post and continue to pull the thread. The thread will drive the cross-shaped fixation post to rotate through the shell. The cross-shaped fixation post will pull the fixation ring and the elastic fastening band, causing the elastic fastening band to roll up onto the fixation ring. The elastic fastening band will gradually tighten, thus making the elastic fastening band fit the user's head to adapt to the user's head shape.

[0019] S4: Turn on the control switch and start the trigger to provide low-intensity transcranial focused ultrasound stimulation to the user.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. When the length of the thread needs to be adjusted, simply pull the thread. After adjusting the thread to the appropriate length, release the thread. The housing will rotate counterclockwise, and the steel ball will be inserted into the third guide groove under the guidance of the rectangular guide groove, the first limiting part, and the second limiting part, thus fixing the thread. To retract the thread, gently pull the thread and then release it. The steel ball will enter the second guide groove along the first limiting part. Then, the housing will continue to rotate counterclockwise to rewind the thread. This device can retract and adjust the length of the thread, making it convenient to use. The thread can be flexibly adjusted in length and quickly retracted, and it is not easy to tangle or knot.

[0022] 2. When the head-mounted protective shell needs to fit snugly against the user's head, the length of the cord is first adjusted. After adjustment, the fixing ring is fastened to the cross-shaped fixing post, and then the cord is pulled. The cord will cause the shell, cross-shaped fixing post, and fixing ring to rotate. The rotating fixing ring can tighten the elastic fastening band, which will fit snugly against the user's head for a more comfortable fit. After adjustment, the cord can be released. During the above process, the rotation of the shell will cause the steel ball to return to the first guide groove under the guidance of the second guide groove and the first limiting part. After the cord is released, the steel ball is once again inserted into the third guide groove, thereby preventing the shell, cross-shaped fixing post, fixing ring, and elastic fastening band from returning to their original positions.

The strap 101 is made of medical-grade elastic nylon, and the head-mounted protective shell 102 is made of ABS engineering plastic. The strap 101 uses elastic contraction to securely fix the head-mounted protective shell 102 on the head, preventing displacement during treatment. The head-mounted protective shell 102 provides protection and a mounting carrier for the triggers 103, isolating them from external interference. The trigger 103, as the core component for ultrasound emission, outputs low-intensity focused ultrasound through the signal transmitted via the wires 104, acting on brain regions related to depression.

[0041] The adjustment component 2 also includes a guide block 204, which is fixed to the outside of the headband protective shell 102. The elastic fastening band 201 is slidably connected inside the guide block 204. The guide block 204 is fixed to the outer wall of the headband protective shell 102 by screws. The elastic fastening band 201 slides against the inner wall of the guide block 204 with a clearance fit. The guide block 204 provides guidance and limitation for the elastic fastening band 201. The elastic fastening band 201 can be adjusted in length and width by sliding within the guide block 204, adapting to users with different head shapes, increasing the contact area with the head, and improving wearing comfort.

[0042] The adjustment component 2 also includes elastic straps 205 and fasteners 206. Multiple elastic straps 205 are provided and are evenly distributed inside the head-mounted protective shell 102. Elastic fastening straps 201 are provided on the elastic straps 205. Fasteners 206 are fixed inside the head-mounted protective shell 102. The fasteners 206 are fixed to one end of the elastic fastening strap 201 inside the head-mounted protective shell 102. The elastic straps 205 are fixed to the inner wall of the head-mounted protective shell 102. The elastic fastening straps 201 and elastic straps 205 are nested together. The elastic straps 205 are used to maintain the shape of the elastic fastening strap 201 inside the head-mounted protective shell 102. When the elastic fastening strap 201 contracts, the elastic straps 205 can deform and move with the elastic fastening strap 201.

[0043] The wire winding component 3 also includes a circular guide groove 307 and a rectangular guide groove 308. Both the circular guide groove 307 and the rectangular guide groove 308 are formed on the second housing 303 and are connected. The housing 3041 is disposed in the circular guide groove 307. The circular guide groove 307 can guide and position the housing 3041.

[0045] The clamping plate 401 is detachably connected to the first housing 301 and the second housing 303 via a snap-fit ​​mechanism. The cleaning block 402 is wrapped with a soft material around the cable 306. When the cable 306 is pulled, the cleaning block 402 can clean the cable 306. The clamping plate 401 and the cleaning block 402 can be removed for cleaning, thus maintaining the cleaning effect of the cleaning block 402 and preventing dirt from affecting the cable 306. The limiting member 304 includes a housing 3041, on which a through hole 3042 is provided. The housing 3041 has a first limiting part 3045 and a second limiting part 3047. A second guide groove 3044, a third guide groove 3046, and a first guide groove 3043 are formed from the inside out between the housing 3041, the first limiting part 3045, and the second limiting part 3047. The limiting member 304 also includes a steel ball 3048, which is movably disposed in the second guide groove 3044, the third guide groove 3046, the first guide groove 3043, and the rectangular guide groove 308. A cross-shaped fixing post 203 is fixed on the housing 3041.

[0046] The first limiting part 3045 and the second limiting part 3047 are integrally formed with the housing 3041. The steel ball 3048 and the second guide groove 3044, the third guide groove 3046, the first guide groove 3043, and the rectangular guide groove 308 are all in rolling contact. The steel ball 3048 is a wear-resistant stainless steel ball. The second guide groove 3044, the third guide groove 3046, and the first guide groove 3043 provide a rolling track for the steel ball 3048. The steel ball 3048 reduces the frictional resistance when the housing 3041 rotates by rolling, making the winding of the line 306 smoother. Rotating the housing 3041 will drive the cross fixing post 203 to rotate synchronously, thereby pulling the fixing ring 202 and the elastic fastening band 201 to wind up, realizing the fit between the elastic fastening band 201 and the head.

[0047] The present invention also provides a method for treating depression, comprising the following steps:

[0048] S1: The head-mounted protective case 102 is worn on the user's head, and the position of the head-mounted protective case 102 is restrained by the strap 101;

[0049] S2: Pull out the cable 306 and connect the cable 306 to the power supply to put the trigger 103 into standby mode;

[0050] S3: Before treating the user, fasten the fixing ring 202 onto the cross-shaped fixing post 203, and continue to pull the thread 306. The thread 306 will drive the cross-shaped fixing post 203 to rotate through the housing 3041. The cross-shaped fixing post 203 will pull the fixing ring 202 and the elastic fastening band 201, so that the elastic fastening band 201 is rolled up on the fixing ring 202. The elastic fastening band 201 will gradually tighten, so that the elastic fastening band 201 fits the user's head to adapt to the user's head shape.

[0051] S4: Turn on the control switch and activate trigger 103 to perform low-intensity transcranial focused ultrasound stimulation on the user through trigger 103;

[0052] In use: When the length of the cable 306 needs to be adjusted, simply pull the cable 306. The cable 306 will cause the housing 3041 to rotate clockwise. The rotation of the housing 3041 will cause the coil spring 305 to deform. The elastic potential energy stored in the deformation of the coil spring 305 can drive the housing 3041 to rotate. During the above process, the steel ball 3048 will continue to rotate on the first guide groove 3043. After the length of the cable 306 is adjusted to the appropriate length, release the cable 306. The housing 3041 will rotate counterclockwise. The steel ball 3048 will rotate on the rectangular guide groove 308 and the first limiting part 3045. The second limiting part 3047 guides the thread into the third guide groove 3046, thus fixing the thread 306. To store the thread 306, gently pull the thread 306 and then release it. After pulling the thread 306, the housing 3041 rotates clockwise, and the steel ball 3048 enters the second guide groove 3044 along the first limiting part 3045. Then, the housing 3041 continues to rotate counterclockwise, thus winding up the thread 306. This device can store and adjust the length of the thread 306. The thread 306 can be flexibly adjusted in length and quickly stored, and is not easy to tangle or knot.

[0053] When the head-mounted protective shell 102 needs to be fitted to the user's head, first adjust the length of the cable 306. After adjustment, fasten the fixing ring 202 onto the cross-shaped fixing post 203, and then pull the cable 306. The cable 306 will drive the shell 3041, the cross-shaped fixing post 203, and the fixing ring 202 to rotate. The rotating fixing ring 202 can tighten the elastic fastening band 201, which will fit snugly against the user's head for a more comfortable fit.

[0054] After adjustment, release the cable 306. During the above process, the rotation of the housing 3041 will cause the steel ball 3048 to rotate back into the first guide groove 3043 under the guidance of the second guide groove 3044 and the first limiting part 3045. After releasing the cable 306, the steel ball 3048 will re-enter the third guide groove 3046, thereby preventing the housing 3041, the cross fixing post 203, the fixing ring 202, and the elastic fastening band 201 from returning to their original positions. Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
