A magnetic coil support of a magnetic stimulator

Abstract

This utility model relates to the field of magnetic coil support technology and discloses a magnetic coil support for a magnetic stimulator. This utility model solves the problem that conventional supports have fewer rotating components for adjustment, resulting in lower adjustment accuracy. To suit patient use, it is even necessary to adjust the position of the connecting rod on the operating table, which is cumbersome. This utility model uses a horizontal rotating component including a rotating disk, a guide ring on the lower side of the rotating disk, a rubber block at the lower end of the guide ring, a connecting frame at the upper end of the connecting rod, and a rubber block at the bottom of the connecting frame. The rotating disk has a connecting seat at the upper end, a connecting block on the connecting seat, and a threaded post in the middle of the connecting seat and the connecting block. One end of the threaded post has a knob. When the rotating disk is rotated and adjusted to a suitable horizontal angle, the rubber blocks alternately block the rotation of the rotating disk. Then, rotating the knob drives the threaded post to rotate, and the connecting block rotates on the connecting seat, thereby adjusting the vertical angle of the connecting rod.

Description

Technical Field

[0001] This utility model relates to the field of magnetic coil support technology, specifically a magnetic coil support for a magnetic stimulator. Background Technology

[0002] As an important diagnostic and treatment device in neurology, rehabilitation, and other fields, the precise positioning and stable support of the magnetic coil in magnetic stimulators are crucial. Currently, most magnetic coil supports in magnetic stimulators have many shortcomings. Some supports have simple structures and limited adjustment ranges, making it difficult to adapt to the differences in body shape and the diverse needs of treatment sites for different patients, resulting in poor magnetic stimulation effects. Other supports lack stability and are prone to shaking during operation, affecting the accuracy of magnetic field focusing and thus interfering with treatment. In addition, the adjustment operation of traditional supports is complicated, requiring a lot of time and energy from medical staff for positioning, reducing the efficiency of diagnosis and treatment. In view of this, it is extremely urgent to develop a magnetic coil support for magnetic stimulators that is flexible in adjustment, highly stable, and easy to operate, which can effectively improve the accuracy and efficiency of magnetic stimulation therapy.

[0003] A Chinese patent with publication number CN212854355U discloses a magnetic coil support for a transcranial magnetic stimulator. The rotating device includes two fixed blocks symmetrically arranged along the vertical center line of a support rod, and a fixed rod is provided between the two fixed blocks. A ring shell is fitted on the fixed rod, and a support rod is fixedly connected to the ring shell. A threaded cavity is provided at the upward-extending end of the support rod, and a fixed knob is threadedly connected inside the threaded cavity. An internal thread is provided near the bottom of the threaded cavity.

[0004] The problem with the aforementioned technologies is that magnetic coil supports are typically composed of multiple connecting rods, with rotating components at the joints of these rods to adjust their horizontal and vertical angles. Conventional supports have fewer rotating components for adjustment, resulting in lower adjustment accuracy. To better suit patient use, it may even be necessary to adjust the position of the connecting rods on the operating table. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic coil support for a magnetic stimulator. By using this device, the problem of magnetic coil supports, which are usually composed of multiple connecting rods with rotating components at the joints to adjust the horizontal and vertical angles of the connecting rods is solved. Conventional supports have fewer rotating components for adjustment, resulting in lower adjustment accuracy. In order to suit the patient, it is even necessary to adjust the position of the connecting rods on the operating table.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic coil support for a magnetic stimulator, comprising an operating table, an adjustment frame at the upper end of the operating table, a connecting rod 1 on the adjustment frame, a connecting rod 2 at the upper end of the connecting rod 1, a horizontal rotation assembly and a vertical rotation assembly between the connecting rod 1 and the connecting rod 2, the horizontal rotation assembly comprising a rotating disk, a guide ring mounted on the lower side of the rotating disk, multiple rubber blocks mounted on the lower end of the guide ring, a connecting frame mounted on the upper end of the connecting rod 1, the connecting frame and the rotating disk being rotatably connected, the guide ring and the inner wall of the connecting frame being slidably connected, multiple rubber blocks also being mounted on the bottom of the connecting frame, the vertical rotation assembly comprising a connecting seat, the lower end of the connecting seat being fixedly connected to the rotating disk, a connecting block on the connecting seat, the upper end of the connecting block being fixedly connected to the connecting rod 2, a threaded rod slidingly passing through the middle of the connecting block, one end of the threaded rod being threaded through the connecting seat, a clamping block being rotatably mounted on the threaded rod, the lower end of the clamping block being slidably connected to the connecting seat, and a knob being mounted on the end of the threaded rod near the clamping block.

[0007] Rotating the rotating disc causes the rubber blocks between the guide ring and the connecting frame to press against each other. After adjusting to a suitable horizontal angle, stop rotating. The rubber blocks on the guide ring are blocked by the adjacent rubber blocks on the connecting frame, thus preventing the rotating disc from rotating. This completes the adjustment of the horizontal angle of the second connecting rod. Then, rotate the knob to drive the threaded column to rotate, thereby moving the clamping block away from the connecting block. The connecting block is no longer jointly pressed by the clamping block and the connecting seat, allowing it to rotate around the threaded column on the connecting seat. This adjusts the vertical angle of the second connecting rod, reducing the amount of operation required by the user and making the adjustment more accurate. This makes it easier to adjust the stent to a suitable position for the patient.

[0008] Preferably, the outer side of the rotating disk is provided with anti-slip grooves.

[0009] The anti-slip grooves increase the friction on the surface of the rotating disc, making it easier for users to rotate the disc.

[0010] Preferably, the upper end of the connecting rod 2 is also provided with a horizontal rotation component and a vertical rotation component. The lower end of the horizontal rotation component is fixedly connected to the connecting rod 2. A fixing plate is installed at the upper end of the vertical rotation component. A fixing block is installed on the upper side of the fixing plate. A fixing tube is installed through the middle of the fixing block. A fixing clamp is installed at the upper end of the fixing block.

[0011] The magnetic coil is mounted on the fixing clamp via a fixing tube, and the position of the fixing clamp can be changed by adjusting the horizontal and vertical rotating components.

[0012] Preferably, guide tubes are installed on the outer sides of both connecting rod one and connecting rod two.

[0013] The magnetic coil is guided by a guide tube and a fixing clip, making it easy for the user to use the magnetic stimulator.

[0014] Preferably, a sliding plate is installed at the lower end of the connecting rod, and a moving groove is provided in the adjusting frame. The sliding plate is slidably disposed in the moving groove. Multiple notches are provided in the adjusting frame, and the notches are symmetrically arranged at the upper ends of both sides of the moving groove with the moving groove as the axis. Limiting blocks are installed at both ends of the sliding plate, and the multiple notches are adapted to the limiting blocks. The middle part of the limiting block slides through a limiting post. A sliding groove is provided in the adjusting frame, and the limiting post and the sliding groove are slidably connected. A spring is sleeved on the outside of the limiting post, and the upper end of the spring is fixedly connected to the limiting block, and the lower end of the spring is fixedly connected to the limiting post.

[0015] Pushing the connecting rod downwards causes the sliding plate to move downwards, which in turn moves the limiting block downwards. This causes the limiting block to compress the spring downwards until it leaves the notch. The limiting block is no longer obstructed by the inner wall of the notch and can then push the connecting rod horizontally, allowing the sliding plate to move horizontally within the moving groove. This changes the position of the connecting rod until the limiting block reaches another notch. The spring then compresses the limiting block upwards, causing it to lock into the notch and fix the position of the sliding plate, thereby fixing the position of the connecting rod.

[0016] Preferably, a positioning ring is provided at the upper end of the operating table, and the bottom of the adjusting frame is rotatably connected to the positioning ring.

[0017] By rotating the adjustment frame, the position of connecting rod one can be adjusted more precisely.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: Rotating the rotating disk causes the rubber blocks between the guide ring and the connecting frame to press against each other. After adjusting to a suitable horizontal angle, the rotation stops. The rubber blocks on the guide ring are blocked by the adjacent rubber blocks on the connecting frame, thus preventing the rotating disk from rotating and completing the adjustment of the horizontal angle of the second connecting rod. Then, rotating the knob drives the threaded column to rotate, thereby moving the clamping block away from the connecting block. The connecting block is no longer pressed by the clamping block and the connecting seat, so that the connecting block rotates on the connecting seat with the threaded column as the axis, thereby adjusting the vertical angle of the second connecting rod. This reduces the amount of operation required by the user, makes the adjustment more accurate, and makes it easier to adjust the stent to a suitable position for the patient.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0031] Combination Figures 1-4A magnetic coil support for a magnetic stimulator includes an operating table 1. An adjustment frame 2 is mounted on the upper end of the operating table 1. A connecting rod 3 is mounted on the adjustment frame 2. A connecting rod 4 is mounted on the upper end of the connecting rod 3. A horizontal rotation assembly 5 and a vertical rotation assembly 6 are arranged between the connecting rod 3 and the connecting rod 4. The horizontal rotation assembly 5 includes a rotating disk 51. A guide ring 52 is mounted on the lower side of the rotating disk 51. Multiple rubber blocks 521 are mounted on the lower end of the guide ring 52. A connecting frame 53 is mounted on the upper end of the connecting rod 3. The connecting frame 53 and the rotating disk 5... 1. A rotating connection is formed, with the guide ring 52 and the inner wall of the connecting frame 53 slidingly connected. Multiple rubber blocks 521 are also installed at the bottom of the connecting frame 53. The vertical rotating assembly 6 includes a connecting seat 61, the lower end of which is fixedly connected to the rotating disk 51. A connecting block 62 is provided on the connecting seat 61, and the upper end of the connecting block 62 is fixedly connected to the connecting rod 4. A threaded rod 63 slides through the middle of the connecting block 62, and one end of the threaded rod 63 is threaded through the connecting seat 61. A clamping block 631 is rotatably mounted on the threaded rod 63, and the lower end of the clamping block 631... The connecting rod 63 is slidably connected to the connecting seat 61. A knob 64 is installed at one end of the threaded rod 63 near the clamping block 631. Rotating the rotating disk 51 causes the rubber blocks 521 between the guide ring 52 and the connecting frame 53 to be alternately pressed. After adjusting to a suitable horizontal angle, the rotation is stopped. The rubber blocks 521 on the guide ring 52 are blocked by the adjacent rubber blocks 521 on the connecting frame 53, thereby preventing the rotating disk 51 from rotating, thus completing the adjustment of the horizontal angle of the connecting rod 63. Then, rotating the knob 64 drives the threaded rod 63 to rotate, thereby driving the clamping block 631. Moving away from the connecting block 62, the connecting block 62 is no longer squeezed by the clamping block 631 and the connecting seat 61, so that the connecting block 62 rotates on the connecting seat 61 with the threaded column 63 as the axis, thereby adjusting the vertical angle of the connecting rod 4, reducing the amount of operation required by the user, making the adjustment more accurate, and making it easier to adjust the bracket to a position suitable for the patient. The outer side of the rotating disk 51 is provided with an anti-slip groove 511, which increases the friction of the rotating disk 51 surface, making it easier for the user to rotate the rotating disk 51.

[0032] Combination Figures 1-2 , Figure 5 The upper end of the connecting rod 2 4 is also equipped with a horizontal rotation component 5 and a vertical rotation component 6. The lower end of the horizontal rotation component 5 is fixedly connected to the connecting rod 2 4. The upper end of the vertical rotation component 6 is equipped with a fixing plate 7. A fixing block 71 is installed on the upper side of the fixing plate 7. A fixing tube 72 is installed through the middle of the fixing block 71. A fixing clamp 73 is installed on the upper end of the fixing block 71. The magnetic coil is installed on the fixing clamp 73 through the fixing tube 72. The position of the fixing clamp 73 can be changed by adjusting the horizontal rotation component 5 and the vertical rotation component 6. The outer sides of the connecting rod 1 3 and the connecting rod 2 4 are equipped with guide tubes 33. The magnetic coil is guided to the fixing clamp 73 through the guide tubes 33, which makes it convenient for the user to use the magnetic stimulator.

[0033] Combination Figures 6-9 A sliding plate 31 is installed at the lower end of the connecting rod 3. A moving groove 21 is provided inside the adjusting frame 2. The sliding plate 31 is slidably disposed in the moving groove 21. Multiple notches 211 are provided inside the adjusting frame 2. The bottom ends of the multiple notches 211 are connected. The notches 211 are symmetrically arranged at the upper ends of both sides of the moving groove 21 with the moving groove 21 as the axis. Limiting blocks 32 are installed at both ends of the sliding plate 31. The multiple notches 211 are all adapted to the limiting blocks 32. The middle part of the limiting block 32 slides through. A limiting post 321 is inserted through the adjusting frame 2, and a sliding groove 22 is provided inside the adjusting frame 2. The limiting post 321 and the sliding groove 22 are slidably connected. A spring 322 is sleeved on the outside of the limiting post 321. The upper end of the spring 322 is fixedly connected to the limiting block 32, and the lower end of the spring 322 is fixedly connected to the limiting post 321. The sliding plate 31 is initially located at the upper end of the moving groove 21. At this time, the limiting block 32 is located in the notch 211. Pushing the connecting rod 3 downward causes the sliding plate 31 to move downward until the sliding plate 31 moves downward. The moving plate 31 is located at the lower end of the moving groove 21, thereby driving the limiting block 32 to move downward until the limiting block 32 leaves the notch 211. At this time, the limiting block 32 is also located at the lower end of the moving groove 21, so that the limiting block 32 presses the spring 322 downward. The limiting block 32 is no longer blocked by the inner wall of the notch 211. There are three sets of notches 211. The three sets of notches 211 are equidistantly arranged in the adjusting frame 2. The connecting rod 3 can be pushed horizontally, so that the sliding plate 31 moves horizontally in the moving groove 21, thereby changing the position of the connecting rod 3. Until the limiting block 32 reaches the bottom of another notch 211, the spring 322 presses the limiting block 32 upward, so that the limiting block 32 is stuck in the notch 211, fixing the position of the sliding plate 31, and thus fixing the position of the connecting rod 3. The upper end of the operating table 1 is provided with a positioning ring 11. The bottom of the adjusting frame 2 is rotatably connected to the positioning ring 11. By rotating the adjusting frame 2, the position of the connecting rod 3 can be adjusted more precisely.

[0034] Working principle: Rotating the rotating disk 51 causes the rubber blocks 521 between the guide ring 52 and the connecting frame 53 to press against each other. After adjusting to a suitable horizontal angle, the rotation stops. The rubber blocks 521 on the guide ring 52 are blocked by the adjacent rubber blocks 521 on the connecting frame 53, thus preventing the rotating disk 51 from rotating. This completes the adjustment of the horizontal angle of the connecting rod 4. Then, rotating the knob 64 drives the threaded column 63 to rotate, thereby moving the clamping block 631 away from the connecting block 62. The connecting block 62 is no longer jointly pressed by the clamping block 631 and the connecting seat 61, so the connecting block 62 rotates on the connecting seat 61 with the threaded column 63 as the axis, thereby adjusting the vertical angle of the connecting rod 4. This reduces the amount of operation required by the user, makes the adjustment more accurate, and makes it easier to adjust the stent to a suitable position for the patient.
