  However, with the conventional head support, the patient can move the head to a certain extent, and the patient must continue to make self-help efforts not to move the head during treatment. Since the treatment of cranial nerve diseases is performed for a long period of 30 minutes, it is a burden on the patient to keep nervous while taking care not to move the head.

  If the patient inadvertently moves the head even a little, the relative position between the stimulation point and the coil shifts, adversely affecting the therapeutic effect and making ideal treatment difficult.

  Therefore, the present invention has been made to solve the above-described problems, and provides a support device that can reduce the burden on the patient and reliably support the patient's head for a long time in the treatment of cranial nerve diseases. Objective.

[Magnetic stimulation treatment system]
FIG. 1 is a side view of a magnetic stimulation treatment system 10 according to the present embodiment.

  The illustrated magnetic stimulation apparatus 20 is used in a therapy that directly stimulates the brain, which is one of therapies for cranial nerve diseases such as Parkinson's disease and depression, and rehabilitation after stroke. As a therapy for directly stimulating the brain, a magnetic stimulation therapy that applies magnetic stimulation to a specific part of a patient's head, for example, repetitive transcranial magnetic stimulation (rTMS) is used. Magnetic stimulation therapy is a treatment method that stimulates nerves by inducing an electric field in the skull, and it has features such as being able to stimulate tissues without dissipating magnetic energy, and stimulating the brain more accurately and reliably. Have.

  Referring to FIG. 1, a magnetic stimulation treatment system 10 includes a magnetic stimulation device 20 that stimulates a patient's brain with magnetic energy, and a support device 30 that is used together with the magnetic stimulation device 20 to support the patient during treatment. In the present embodiment, the magnetic stimulation apparatus 20 is exemplified as a medical device that performs an examination and treatment on the patient's head, but the medical device is not limited to this.

[Magnetic stimulator]
The magnetic stimulation apparatus 20 suspends and supports a magnetic stimulation coil 21 (hereinafter, also simply referred to as “coil 21”) as a medical device, a coil attachment portion 22 on which the coil 21 is attached on the lower surface side, and the coil attachment portion 22. The arm 23 includes an arm attachment portion 24 to which a base end portion of the arm 23 is attached, a post portion 25 that supports the arm attachment portion 24, and a cart portion 26 to which the post portion 25 is attached.

  The coil 21 generates magnetism that stimulates a specific part of the head of the living body (patient) and applies magnetic stimulation to the patient's head. The coil element incorporated in the coil 21 may appropriately adopt a shape such as a circular shape, an 8-shaped shape, or a conical shape. Since the shape of the magnetic field applied to the head differs depending on the shape, for example, the shape of the coil element to be employed is selected according to the type of cranial nerve disease. Since a large current on the order of several thousand A flows through the coil element, a cooling unit (not shown) for cooling the coil element is attached around the coil element. The coil 21 is detachably attached to the coil attachment portion 22. Depending on the treatment content, the coil 21 is replaced with a coil 21 having a different shape. The cooling part of the coil 21 is connected to a chiller device 41 built in the cart part 26. The chiller device 41 supplies the cooled refrigerant to the cooling unit via the supply hose 42a. The refrigerant that has cooled the coil element is returned from the cooling unit to the chiller device 41 via the discharge hose 42b.

  The coil attachment portion 22 is suspended and supported on the lower surface side of the tip of the arm 23 via a ball joint 43. The coil attachment portion 22 can adjust the posture with respect to the arm 23 to a desired posture by the ball joint 43. The base end portion of the arm 23 is attached to the arm attachment portion 24 via the joint portion 44. By the joint portion 44, the arm 23 is rotatable in a vertical plane. The arm attachment portion 24 is attached to the post portion 25 via a bearing portion (not shown). The arm attachment portion 24 is rotatable in a horizontal plane by the bearing portion. The post portion 25 is attached to the upper surface of the cart portion 26 via a slide mechanism so as to be slidable in a direction approaching and separating from the patient (left and right direction on the paper surface). An arm assembly is configured by the arm 23, the arm mounting portion 24, and the post portion 25. The arm assembly slides through the slide mechanism.

  By adjusting the posture of the coil attachment portion 22 with respect to the arm 23, turning the arm 23 in the vertical plane, turning the arm attachment portion 24 in the horizontal plane, and sliding the post portion 25, the coil 21 with respect to the patient's head is moved. The posture can be adjusted to a desired posture. Magnetic stimulation must be applied accurately to specific parts of the patient's head. For this reason, when the adjustment of the posture of the coil 21 is finished, the ball joint 43, the joint portion 44, the bearing portion, and the slide mechanism are locked in an inoperable state. Thereby, the coil 21 is positioned with high accuracy.

  In addition to the chiller device 41, the cart unit 26 includes a current supply device 45 that houses electrical components that supply a large current to the coil element, and a controller 46 that controls the operation of the entire magnetic stimulation therapy system 10. The controller 46 receives the temperature of the coil element, a signal from the chiller device 41, a signal from the current supply device 45, a biological signal acquired from the living body, and the like via the input / output unit. As a biological signal, the patient's electrocardiogram signal, the transmissivity of red light and infrared light of blood flowing through the patient's fingertip (to measure arterial oxygen saturation (hereinafter referred to as SpO2)), biological myoelectric signal, etc. There is. From the controller 46, a signal for controlling the operation of the chiller device 41, a signal for the operation of the current supply device 45, and the like are output via the input / output unit. A monitor 47 connected to a controller 46 is attached to the cart unit 26. The monitor 47 displays the operating state of the current supply device 45, the patient's state, and the like. The controller 46 can control the operation of the current supply device 45 using the biological signal, and can control the intensity of the magnetic stimulation that the coil 21 gives to the living body.

  A caster 48 is provided on the lower surface of the cart portion 26. The cart unit 26 and the magnetic stimulation device 20 can be moved by a caster 48. The caster 48 includes a lock mechanism (not shown). The lock mechanism securely locks the rotation of the caster 48. Thereby, the position of the coil 21 positioned with high accuracy by the arm 23 is reliably maintained.

The support device 30 includes a seat 50 including a seat portion 31 on which a patient sits, a backrest portion 32 that supports the patient's back, a foot support 33, a base portion 34 that supports the seat portion 31, and a base portion 34. A caster 35 attached to the lower surface is provided. The seat portion 31, the backrest portion 32, and the foot support 33 are adjustable in inclination angle according to the posture of the patient. An armrest 36 is attached to the side of the seat portion 31. A head support 37 for supporting the patient's head is attached to the seat 50. Specifically, the head support 37 is attached to the top 55 of the backrest 32. The head support 37 is supported by the position adjustment mechanism 60 so as to be movable up and down along the length direction of the backrest portion 32. Therefore, the position of the head support 37 can be adjusted to an optimum position for each patient position adjustment.

  When the patient sits on the seat 31 of the support device 30, puts his / her foot on the foot support 33, puts his / her back on the backrest 32, and places the head on the head support 37 adjusted to the height of the patient's head by the position adjustment mechanism 60. The position of the patient's head is almost determined. Although not clearly shown in FIG. 1, the head support 37 is provided with a portion that rotates from the lateral direction of the patient and supports the lower jaw of the patient while applying pressure from the lateral direction. In this part, the position of the patient's lower jaw is firmly fixed, and the position of the patient's head is fixed.

  The support device 30 is movable by a caster 35. The caster 35 includes a lock mechanism (not shown). The lock mechanism securely locks the rotation of the caster 35. This ensures that the position of the patient's head is maintained.

  The position of the patient's head is fixed by the support device 30, and the coil 21 is adjusted to the position of the patient's stimulation point by the arm 23. As a result, an ideal treatment for cranial nerve disease can be performed on the patient.

[Head support]
Next, the head support 37 of the support device 30 according to the present embodiment will be described in detail with reference to FIGS.

  2 to 4, the patient 100 sits on the seat 31 of the support device 30 shown in FIG. 1, places his / her foot on the foot support 33, puts his back on the backrest 32, and places his / her head on the head support 37. It is in a state. The head support 37 is attached to the top 55 of the backrest 32.

  As shown in FIGS. 2 to 4, 5, and 7, the head support 37 includes a base 70 that supports the occipital region of the patient 100, and an angle with respect to the base 70 that is adjustable on each side of the base 70. It has movable portions 72a and 72b which are provided so as to be able to maintain the angle and restrain the movement of the cervical rotation and lateral bending by contacting at least the lower jaw of the patient 100.

  As shown in FIGS. 3 and 4, the base portion 70 of the head support 37 is fixed to the mounting stay 38 by mounting screws 51. The attachment stay 38 is attached to a support stay 39 attached to the backrest 32 so that the angle can be adjusted. In this way, the head support 37 is attached to the top 55 of the backrest 32.

  When adjusting the mounting angle of the head support 37, the fixing screw 52 of the support stay 39 is loosened, the mounting stay 38 is moved so that the fixing screw 52 is positioned in a different angle adjusting hole 53, and the fixing screw 52 is tightened. This angle adjustment can be performed in three stages as shown in FIG. Therefore, the mounting angle of the head support 37 can be adjusted to an optimum angle for each patient 100.

  As shown in FIG. 5 and FIG. 7, the base 70 has a recess 73 that is opened in a U-shape. Due to the presence of the recess 73, the back of the patient 100 can be stably supported. The height of the base 70 is about half of the head of the patient 100. The movable portions 72a and 72b that are rotatably attached to the base portion 70 have a shape that exposes the ear 101 of the patient 100, and can support at least the lower jaw of the patient 100 while pressing from the side. Have

  As can be seen with reference to FIG. 2, if the shape of the movable parts 72 a and 72 b is not devised, the movable parts 72 a and 72 b are rotated to support the lower jaw of the patient 100 while pressing from the side. The ear 101 of the patient 100 gets in the way. Therefore, the shapes of the movable portions 72a and 72b are curved in order to avoid the ear 101 of the patient 100, as shown in FIGS. In addition, a certain length is required to stably support the lower jaw of the patient 100 from the side. For this reason, the length of the movable parts 72a and 72b is set to a length that can support the lower jaw of the patient 100 as shown in FIGS.

  Therefore, the movable parts 72a and 72b can support the patient's lower jaw while pressing with a constant force without being obstructed by the ear 101 of the patient 100. Moreover, the coil 21 (refer FIG. 1) can be positioned in the wide range of the head of the patient 100, and various cranial nerve diseases can be treated without being obstructed by the movable parts 72a and 72b.

  As shown in FIGS. 6 and 8, the base portion 70 includes a plate portion 74 connected to the top portion 55 of the backrest portion 32 of FIG. 1, and a cushion material (not shown) attached so as to surround the plate portion 74. Have Further, each of the movable portions 72a and 72b is attached so as to surround the side plate portions 76a and 76b and the side plate portions 76a and 76b that are rotatably connected to the plate portion 74 of the base portion 70. A cushion material (not shown).

  Further, a cushion material (not shown) for the base portion 70 and a cushion material (not shown) for the movable portions 72a and 72b are respectively sponge materials (not shown) surrounding the plate portion 74 and the side plate portions 76a and 76b. And an epidermis (not shown) surrounding the sponge material and in contact with the patient 100. A urethane material is suitable as the sponge material, and genuine leather and synthetic leather are suitable as the skin.

  In this way, the cushion material is attached so as to surround the plate portion 74, and the cushion material is attached so as to surround the side plate portions 76a, 76b, thereby forming the head support 37 as shown in FIGS. can do. Therefore, the head of the patient 100 can be stably supported. Moreover, the durability of the cushioning material can be enhanced by configuring the cushioning material with a sponge material and an epidermis, and the patient 100 can feel better.

  As shown in FIGS. 6, 8, and 9, the plate portion 74 and the side plate portions 76 a and 76 b have a torque hinge 75 that can freely load a rotational torque that maintains the angle of the movable portions 72 a and 72 b with respect to the base portion 70. It is connected via a pivot. The torque hinge 75 opens or closes the side plate portion 76 a with respect to the plate portion 74 when a rotational force with a torque equal to or greater than a set constant torque is applied.

  Therefore, the movable portions 72a and 72b can freely adjust the angle with respect to the base portion 70, and further can maintain the angle. For this reason, the movable parts 72a and 72b can restrain the rotation of the neck part and the lateral bending movement by contacting at least the lower jaw of the patient 100. Further, when the patient 100 feels something wrong, when the head is deliberately moved with a force equal to or greater than the above-mentioned constant torque, the movable parts 72a and 72b are opened with respect to the base part 70, and in the open position. By stopping, the patient is free from the failure.

  As shown in FIGS. 2 to 4, a belt 105 for fixing the forehead is hung on the forehead 102 of the patient 100. The belt 105 is detachably attached to the base portion 70. The belt 105 is stretched around the forehead 102 of the patient 100 and restrains the patient's 100 neck from moving forward.

  The belt 105 includes a second hook-and-loop fastener 107 that can be attached to and detached from the first hook-and-loop fastener 106 attached to both ends of the rear portion of the base portion 70.

  As shown in FIG. 2, the belt 105 is stretched around the forehead 102 of the patient 100, and second hook-and-loop fasteners 107 at both ends of the belt 105 are attached to both ends of the rear portion of the base 70 shown in FIGS. The first hook-and-loop fastener 106 is attached. As a result, the belt 105 can restrain the forward movement of the neck of the patient 100 as shown in FIG.

  When the patient 100 receives treatment, first, the position adjustment mechanism 60 adjusts the movable parts 72 a and 72 b of the head support 37 to a position below the ear 101 of the patient 100. Next, the lower part of the patient 100 is supported by the movable parts 72a and 72b so as to be pressurized from both sides. Finally, the head of the patient 100 is fixed by the belt 105. In this way, the movement of the patient's 100 head flexion and extension, the patient's 100 head flexion movement and the right flexion movement, and the patient's 100 head rotation movement are constrained, and the coil 21 (FIG. 1) and a large relative displacement between the stimulation points can be prevented.

[Operation of magnetic stimulation treatment system]
Next, the operation of the magnetic stimulation therapy system 10 according to the present embodiment will be described with reference to FIGS.

  First, before starting treatment by magnetic stimulation therapy, the operator places the patient 100 on the support device 30 and places the head on the head support 37. Until the patient 100 starts treatment, the movable parts 72 a and 72 b of the head support 37 are opened away from the lower jaw of the patient 100. Next, the surgeon adjusts the height of the head support 37 so that the movable portions 72 a and 72 b do not get in the way of the ear 101 of the patient 100. When the height is adjusted, the movable parts 72a and 72b are closed from both sides with respect to the lower jaw of the patient 100 from the opened state. The movable parts 72a and 72b fix the lower jaw of the patient 100 while pressurizing with a constant torque. The occipital region of the patient 100 is fitted into the recess 73 formed in the base 70. Finally, the belt 105 is hung on the forehead 102 of the patient 100 and the second hook-and-loop fasteners 107 at both ends thereof are fixed to the first hook-and-loop fasteners 106 attached to both ends of the head support 37.

  As described above, the head of the patient 100 is fixed to the head support 37. Next, the position of the coil 21 is precisely set to a position suitable for treating the symptoms of the patient 100. Whether or not the position of the coil 21 is appropriate can be confirmed by the display on the monitor 47 (part receiving magnetic stimulation).

  When the treatment is started, the controller 46 controls the current supply device 45 to supply a current to the coil 21. An electric field is induced from the coil 21 into the skull of the patient 100, and magnetic stimulation is applied to the head of the patient 100. By this magnetic stimulation, for example, a cranial nerve disease such as Parkinson's disease is treated. The controller 46 controls the intensity of the magnetic stimulation by changing the magnitude of the current output to the coil 21, the interval at which the current flows, and the time.

  The controller 46 displays electrocardiogram data, SpO2, electromyogram data, and the like on the monitor 47 based on the biological signal (electrocardiogram signal, permeability, electromyogram signal) of the patient 100. By viewing these displays, the surgeon can easily grasp the status of treatment and the condition of the patient 100 being treated. The operator appropriately adjusts the intensity of the magnetic stimulation according to the condition of the patient 100 while monitoring the condition of the patient 100.

  The operation of the magnetic stimulation therapy system 10 according to the present embodiment is as described above. In this embodiment, the magnetic stimulation treatment system 10 was illustrated as a medical instrument. In the magnetic stimulation treatment system 10, the relative position fluctuation between the coil 21 and the stimulation point on the head of the patient 100 is required to be as small as possible. The present invention is most suitably applied to the magnetic stimulation treatment system 10. For this reason, the effect of the present invention can be maximized by applying the present invention to the magnetic stimulation treatment system 10.

  As described above, according to the support device 30 according to the present embodiment, the patient 100 can sit comfortably for a long time by the movable parts 72a and 72b. In addition, since the relative displacement between the coil 21 and the head is small, the patient 100 can receive an ideal treatment.

  In the above, the technical idea of this invention was demonstrated using embodiment called a magnetic stimulation treatment system. However, the technical idea of the present invention is not limited to the above-described embodiment.
