Description

Technical Field

[0001] This application relates to the field of TMS treatment instrument technology, and in particular to a head fixation device for supine TMS treatment. Background Technology

[0002] Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation technique that induces electrical activity in subcortical neurons by delivering magnetic pulses near the scalp, thereby modulating neural activity in the brain. TMS technology has been widely used in clinical and research fields, showing good results in the treatment of diseases such as depression, schizophrenia, and post-stroke rehabilitation.

[0003] Transcranial magnetic stimulation (TMS) devices are instruments used to perform transcranial magnetic stimulation therapy. Their structure mainly includes a main motor housing, coils for stimulation, and a support arm for supporting the coils, such as the transcranial magnetic electrotherapy device with publication number CN105194802A. However, in this device, the coils and support are fixed to one side, limiting the range of motion. The coils often only cover one side of the target area, affecting the treatment effect. Furthermore, switching between different target areas requires significant adjustments to the position and angle of the support arm, necessitating the adjustment of multiple tightening screws, making operation cumbersome. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention slides a coil support along a support track, surrounding the treatment area. Therefore, in practical use, the coil support can cover the entire target area. Furthermore, when switching targets, it is only necessary to drive the coil support to the target position and then determine whether fine-tuning of the coil support's angle is needed, without requiring significant adjustments to the coil support's angle, making operation much simpler.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a head fixation device for supine TMS treatment, comprising: a base plate, wherein a treatment area for supporting the patient's head is provided on the base plate; An arc-shaped support track is disposed on the substrate, surrounding the treatment area; A slider, which is slidably mounted on the support track; A coil support, one end of which is disposed on the slider, and the other end forms a mounting portion for mounting the coil support.

[0006] Furthermore, the slider is arc-shaped, and the arc of the slider is the same as the arc of the support track, with the center of the arc of the support track located in the treatment area.

[0007] Furthermore, the coil support includes: a telescopic vertical rod, which is vertical and rotatably mounted on the slider in its circumferential direction; A retractable crossbar, which is connected to the vertical bar; The mounting part is located at one end of the horizontal bar away from the vertical bar and is used to mount the coil.

[0008] Furthermore, the coil support also includes: a plurality of fastening screws, which are respectively disposed on the vertical rod and the horizontal rod, and are used to restrict the relative rotation of the vertical rod and the slider, restrict the extension and retraction of the vertical rod, and restrict the extension and retraction of the horizontal rod.

[0009] Furthermore, the head fixation device also includes: an adjustable pillow, the length of which is driven to change to match the size of the patient's head; The adjustable pillow includes: a pillow track, which is disposed on the base plate, and the two ends of the pillow track are disposed opposite to the two ends of the support track; Two sliding parts are respectively slidably disposed on the pillow section track; A support membrane, the two ends of which are respectively connected to the two sliding portions, and the surface of the support membrane facing away from the substrate forms the treatment area.

[0010] Furthermore, the adjustable pillow also includes a winding device disposed on one or both of the sliding portions, the winding device being used to wind or release the support membrane to change the size of the treatment area.

[0011] Furthermore, the winding device includes: a winding shaft, which is rotatably disposed on the sliding portion and used to wind or release the support film, wherein the support film is driven to release from the winding shaft; A driving assembly connected to the winding shaft, the driving assembly being used to drive the winding shaft to wind the support film; A limiting component is disposed on the sliding portion, and the limiting component is used to restrict the release of the support film by the winding shaft.

The movable limiting part has a movable end facing the treatment area at one end and a limiting end at the other end. The movable end is driven by the support membrane to rotate toward the substrate, thereby driving the limiting end to move toward the fixed limiting part to clamp the support membrane.

[0013] Furthermore, the head fixation device also includes two limiting pillows, which are respectively disposed on one end of the two sliding portions away from the base plate. The two limiting pillows and the support membrane form the treatment area, and the two limiting pillows are used to restrict the patient's head movement.

[0014] Furthermore, the head fixing device also includes an adjusting screw, which is disposed on the base plate and is connected to two sliding parts respectively. The two sliding parts are driven by the adjusting screw to move synchronously and move closer or further away from each other.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] The invention will be further explained below with reference to the accompanying drawings and the description of the embodiments.

[0023] This embodiment provides a head fixation device for supine TMS treatment, such as... Figures 1 to 4 As shown, in order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: including a substrate 100, a slider 300, a coil support 400 and an arc-shaped support track 200.

[0024] A treatment area 621 supporting the patient's head is provided on the substrate 100. A support track 200 is disposed around the treatment area 621 on the substrate 100. A slider 300 is slidably disposed on the support track 200. One end of the coil support 400 is disposed on the slider 300, and the other end forms a mounting part 430 for mounting the coil support 400.

[0025] In practical use, the patient lies on the base plate 100, which can be a bed, mattress, or simply a cushion supporting the patient's head. The support track 200 is preferably semi-circular, with its two ends located on the left and right sides of the patient, allowing the slider 300 to slide along the sides and top of the patient's head. Preferably, the plane formed by the support track 200 is horizontal, so that the slider 300 remains stationary on the support track 200 when no external force is applied, thus allowing the slider 300 to be fixed to any part of the support track 200. To better ensure the stability of the slider 300, rubber or silicone blocks can be placed between the support track 200 and the slider 300 to increase friction. After the patient lies on the base plate 100, medical personnel can fix the coil to the mounting part 430 and then push the slider 300 to slide along the support track 200. During this time, the mounting part 430 can move around the patient's head. When the coil reaches the vicinity of the target area, the pushing of the slider 300 is stopped. Finally, the coil support angle was fine-tuned by 400 degrees so that the coil could cover the target position.

[0026] Understandably, existing transcranial magnetic stimulation (TMS) devices used in hospitals mainly consist of a main motor housing, coils, and a support arm. The control panel is located in the middle of the main motor housing and faces the medical staff. However, the coils are connected to one side of the main motor housing via cables, usually the left side. When using the device, the patient faces the medical staff and sits on the left side of the main motor housing. Due to the limitation of the support arm, the coils can often only contact and cover a single area of ​​the patient's head, affecting the treatment effect. Furthermore, the support arm is generally composed of three interconnected support rods. Therefore, when switching between different target areas, it is often necessary to adjust the position and angle of all three support rods simultaneously, requiring the adjustment of multiple tightening screws, which is cumbersome.

[0027] In one embodiment, such as Figures 1 to 3 As shown, the slider 300 is arc-shaped, and the arc of the slider 300 is the same as the arc of the support track 200. The center of the arc of the support track 200 is located in the treatment area 621.

[0028] Specifically, the arc of slider 300 is the same as that of the support track 200, and the center of arc of slider 300 coincides with the center of arc of support track 200. When slider 300 slides on support track 200, the position of the center of arc of slider 300 remains unchanged. Therefore, when mounting part 430 faces the center of arc of support track 200, no matter where slider 300 slides, slider 300 will drive mounting part 430 to face the center of arc of support track 200, thus ensuring that mounting part 430 is always facing treatment area 621. Therefore, in actual use, when medical staff push slider 300 to move, mounting part 430 will move around the patient's head with coil, and the coil will always face the patient's head. After the coil covers the target area, the angle of coil support 400 can be finely adjusted as needed, without the need for significant adjustments to the angle and position of coil support 400, which is more convenient.

[0029] In one embodiment, such as Figures 1 to 3 As shown, the coil support 400 includes a telescopic vertical rod 410, a horizontal rod 420, and a mounting part 430. The vertical rod 410 is connected to the horizontal rod 420, and the vertical rod 410 is vertically mounted on the slider 300 and rotatably mounted thereon. The mounting part 430 is located at the end of the horizontal rod 420 opposite to the vertical rod 410 and is used to mount the coil.

[0030] Specifically, the vertical rod 410 and the horizontal rod 420 are arranged in an L-shape to form an L-shaped support. Both ends of the L-shaped support are extendable. One end of the L-shaped support is rotatably mounted on the slider 300, and the other end is used to mount the coil. In actual use, the user can rotate the L-shaped support to move the coil within the treatment area 621, thereby changing the coil's position. Simultaneously, by adjusting the lengths of both ends of the L-shaped support, the distance between the coil and the substrate 100, and the distance between the coil and the patient's head, can be adjusted respectively.

[0031] In one embodiment, such as Figures 1 to 3 As shown, the coil support 400 also includes a plurality of fastening screws 440, which are respectively disposed on the vertical rod 410 and the horizontal rod 420, and are used to restrict the relative rotation of the vertical rod 410 and the slider 300, restrict the extension and retraction of the vertical rod 410, and restrict the extension and retraction of the horizontal rod 420.

[0032] Specifically, both the vertical rod 410 and the horizontal rod 420 include a cylindrical body and a sliding rod. The sliding rod is slidably disposed within the cylindrical body along its axial direction. One end of the fastening screw 440 passes through the cylindrical body and contacts the sliding rod. Simultaneously, the fastening screw 440 is threadedly connected to the cylindrical body. In practical use, adjusting the pressure between the fastening screw 440 and the sliding rod allows or prevents relative sliding between the cylindrical body and the sliding rod, thus limiting the extension and retraction of the L-shaped bracket. The vertical rod 410 also includes a rotating flange. One end of the fastening screw 440 passes through the rotating flange and contacts the slider 300. Simultaneously, the fastening screw 440 is threadedly connected to the rotating flange. In practical use, adjusting the pressure between the fastening screw 440 and the slider 300 allows or prevents relative rotation between the vertical rod 410 and the slider 300, thus limiting the rotation of the L-shaped bracket.

[0033] In one embodiment, such as Figures 1 to 3 As shown, the head fixation device also includes an adjustable pillow 600, the length of which is driven to change in order to match the size of the patient's head, thereby making the adjustable pillow 600 suitable for patients with different head circumferences.

[0034] In one embodiment, such as Figures 1 to 3 As shown, the adjustable pillow 600 includes: a pillow track 500, a support membrane 620, and two sliding parts 610.

[0035] A occipital track 500 is mounted on the base plate 100, with its two ends facing the two ends of the support track 200. This allows the two ends of the support track 200 to be positioned on the left and right sides of the patient, enabling the slider 300 to slide along the sides and top of the patient's head. Two sliding portions 610 are slidably mounted on the occipital track 500, and the two ends of a support membrane 620 are connected to the two sliding portions 610. The support membrane 620 forms a treatment area 621 on the surface away from the base plate 100. In actual use, the length of the support membrane 620 can be adjusted by adjusting the distance between the two sliding portions 610, thereby adjusting the size of the treatment area 621 to suit patients with different head circumferences. Preferably, one or both ends of the support membrane 620 are detachably connected to the two sliding portions 610 via Velcro. During use, the distance between the two sliding portions 610 can be adjusted according to the patient's head circumference before connecting the support membrane 620 to the two sliding portions 610.

[0036] It should be noted that TMS treatment requires the patient's head to remain still, but in practice, it is difficult for a person's head to remain in a fixed position for an extended period. If the head shifts, the area of ​​the lesion targeted by the coil will also move, leading to reduced precision of stimulation and compromising the treatment's effectiveness.

[0037] Preferably, the support membrane 620 has a certain degree of elasticity, allowing it to slightly sink under the pressure of the patient's head during use, thus conforming to the patient's head. Alternatively, the width can be adjusted according to the patient's head circumference to ensure a proper fit. This provides some restraint to the patient's head, preventing head movement during treatment.

[0038] In one embodiment, such as Figures 4 to 6 As shown, the adjustable pillow 600 also includes a winding device 630, which is disposed on one or two sliding portions 610. The winding device 630 is used to wind or release the support membrane 620 to change the size of the treatment area 621.

[0039] Specifically, the winding device 630 is disposed within one or two sliding portions 610. The sliding portion 610 is provided with a hole for the support membrane 620 to pass through. The hole is located at the upper end of the sliding portion 610 or flush with the top of the sliding portion 610, so that the top surface of the sliding portion 610 can also support the patient's head.

[0040] In one embodiment, such as Figures 4 to 6 As shown, the winding device 630 includes a winding shaft 631, a drive assembly 632, and a limiting assembly 633. The winding shaft 631 is rotatably disposed inside the sliding portion 610 and is used to wind or release the support membrane 620. In actual use, when the patient's head comes into contact with the support membrane 620 or when the two sliding portions 610 are driven away, pressure is applied to the support membrane 620, thereby driving the support membrane 620 to be released from the winding shaft 631.

[0041] The drive assembly 632 is preferably a torsion spring, which is connected to the winding shaft 631 and the sliding part 610 respectively. The torsion spring can be pre-compressed so that the winding shaft 631 has the force to wind the support membrane 620. When the force on the support membrane 620 disappears, the torsion spring can drive the winding shaft 631 to retract the support membrane 620. The limiting assembly 633 is provided on the sliding part 610. Since the support membrane 620 will release when subjected to force, the limiting assembly 633 can limit the release of the support membrane 620 by the winding shaft 631, thereby preventing the support membrane 620 from continuously releasing when the patient's head comes into contact with it. In actual use, medical staff first drive the two sliding parts 610 closer or further apart to adjust the length of the support membrane 620, and then use the limiting assembly 633 to lock the two ends of the support membrane 620 to the two sliding parts 610, so that the support membrane 620 cannot be extended or shortened. At this time, the patient can lie down and place his head on the support membrane 620 for support.

[0042] In one embodiment, such as Figures 4 to 6As shown, the limiting component 633 includes a fixed limiting part 6331 and a movable limiting part 6332. The fixed limiting part 6331 is disposed on the sliding part 610, and the movable limiting part 6332 is rotatably disposed on the sliding part 610, with the movable limiting part 6332 located below the fixed limiting part 6331. A support membrane 620 is disposed between the fixed limiting part 6331 and the movable limiting part 6332.

[0043] In actual use, medical staff first drive the two sliding parts 610 closer or further away to adjust the length of the support membrane 620. Then, the patient can lie down and place their head on the support membrane 620. At this time, the end of the support membrane 620 near the sliding part 610 is subjected to force and rotates downward, thereby contacting the movable limiting part 6332 and driving its right end (movable end 6332a) to swing, so that the movable limiting part 6332 rotates clockwise, thereby driving the left end (limiting end 6332b) of the movable limiting part 6332 to move upward. Since the distance between the left end of the movable limiting part 6332 and the fixed limiting part 6331 is reduced, the support membrane 620 can be clamped, so that the support membrane 620 cannot be extended or shortened.

[0044] In one embodiment, such as Figure 6 As shown, the support membrane 620 has a plurality of locking holes 622 spaced apart along its extension direction. A buckle 6331a is provided at the left end of the fixed limiting part 6331, and a spring 634 is provided at the right end of the movable limiting part 6332 to drive it to rotate counterclockwise. In actual use, after the patient places their head on the support membrane 620, the support membrane 620 is subjected to force, which drives the right end of the movable limiting part 6332 to swing downwards and move the left end of the limiting part upwards, thereby pushing the support membrane 620 toward the buckle 6331a. When the buckle 6331a engages with the locking holes 622 on the support membrane 620, it restricts the movement of the support membrane 620, preventing it from extending or shortening. When the patient's head leaves the support membrane 620, the force on the movable limiting part 6332 disappears, and the spring 634 drives the movable limiting part 6332 to rotate counterclockwise, thus allowing the support membrane 620 to separate from the buckle 6331a without being subjected to an upward force. Better, such as Figure 6 As shown, the latch 6331a is a triangular prism with one corner facing the support membrane 620. The left side of the latch 6331a is vertically downward, while the right side is inclined. Therefore, when the latch 6331a engages with the latch hole 622, it effectively restricts the movement of the support membrane 620. When the patient's head leaves the support membrane 620, the support membrane 620 can move downward. Simultaneously, because the torsion spring exerts a leftward force on the support membrane 620 through the winding shaft 631, the support membrane 620 can move downward along the right side of the latch 6331a to separate from it.

[0045] In one embodiment, such as Figures 1 to 3 As shown, the head fixation device also includes two limiting pillows 640, which are respectively disposed on one end of the two sliding parts 610 away from the base plate 100. The two limiting pillows 640 and the support membrane 620 form a treatment area 621. The two limiting pillows 640 are used to restrict the patient's head movement.

[0046] In practical use, the two limiting pillows 640 can apply pressure to both sides of the patient's head to limit its movement. Preferably, the two limiting pillows 640 can be slidably mounted on the two sliding parts 610 along the direction of the occipital track 500. At the same time, a compression spring or other device can be provided to drive the two limiting pillows 640 to move relative to each other to avoid the two limiting pillows 640 applying excessive pressure to the patient's head.

[0047] In one embodiment, such as Figures 1 to 3 As shown, the head fixing device also includes an adjusting screw 700, which is disposed on the base plate 100 and is connected to two sliding parts 610 respectively. The two sliding parts 610 are driven by the adjusting screw 700 to move synchronously and move closer or further away from each other.

[0048] Preferably, the adjusting screw 700 is disposed within the pillow track 500, with one end protruding from the base plate 100 and equipped with a hand-tightening adjustment part, so that medical personnel can manually rotate the adjusting screw 700. The adjusting screw 700 is composed of two screws with opposite threads connected together, and the middle of the two screws coincides with the middle of the pillow track 500. When the adjusting screw 700 is driven to rotate, the two sliding parts 610 can be driven to move synchronously in opposite directions, thereby achieving the effect of adjusting the length of the adjusting pillow 600 without changing the center position of the adjusting pillow 600.

[0049] In summary, this application relates to the field of TMS treatment instrument technology and discloses a head fixation device for supine TMS treatment, which includes a base plate, a slider, a coil support, and an arc-shaped support track. The base plate has a treatment area supporting the patient's head. The support track surrounds the treatment area on the base plate. The slider is slidably mounted on the support track. One end of the coil support is mounted on the slider, and the other end forms a mounting portion for mounting the coil support. This invention, by sliding the coil support on the support track and surrounding the treatment area, allows the coil support to cover the entire target area in actual use. Furthermore, when switching targets, it is only necessary to drive the coil support to the target position and then determine whether the angle of the coil support needs to be fine-tuned, without requiring a large adjustment of the coil support angle, making operation simpler.
