DETAILED DESCRIPTION

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0039] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0040] Example 1

[0041] like Figures 1 to 4 As shown, a head-mounted charging device corresponding to an embodiment of the utility model includes a head circumference mechanism 1 and a charging mechanism 2, and may also include a position adjustment mechanism 3.

[0042] The head circumference mechanism 1 may include a fixing unit 11 and an adjusting unit 12. The fixing unit 11 is used to surround the patient's head so that the head-mounted charging device can be installed on the patient's head. The fixing unit 11 can form an annular structure that matches the outer contour of the patient's head so as to be easily mounted on the patient's head.

[0043] The head circumference mechanism 1 may include a first part 111 and a second part 112 separated from each other in the radial direction of the head circumference mechanism 1. The inner peripheries of the first part 111 and the second part 112 jointly form an inner contour in contact with the patient's head, and by adjusting the spacing between the first part 111 and the second part 112, the size of the inner contour jointly formed by the first part 111 and the second part 112 can be adjusted, so that the inner contour jointly formed by the first part 111 and the second part 112 can be adapted to the outer contours of different patients' heads.

[0044] The distance between the first part 111 and the second part 112 can be adjusted by the adjustment unit 12. The adjustment unit 12 may include a telescopic assembly 121. The telescopic assembly 121 may be used to connect the first part 111 and the second part 112, so that when the telescopic assembly 121 is extended, the distance between the first part 111 and the second part 112 becomes larger, that is, the inner contour size formed by the first part 111 and the second part 112 becomes larger; when the telescopic assembly 121 is retracted, the distance between the first part 111 and the second part 112 becomes smaller, that is, the inner contour size formed by the first part 111 and the second part 112 becomes smaller.

[0045] The telescopic assembly 121 may include a telescopic band 1211. One end of the telescopic band 1211 is connected to the first part 111, and the other end is connected to the second part 112. When an external force is applied to the first part 111 and / or the second part 112, the telescopic band 1211 may be extended and a restoring force may be generated, and at the same time, the distance between the first part 111 and the second part 112 increases, that is, the inner contour size formed by the first part 111 and the second part 112 increases. When the external force disappears, the telescopic band 1211 may be retracted under the action of the restoring force, so that the distance between the first part 111 and the second part 112 decreases, that is, the inner contour size formed by the first part 111 and the second part 112 decreases.

[0046] Among them, the retractable belt 1211 can be an elastic belt, and the retractable belt 1211 generates elastic force as a restoring force when stretched. When in use, the retractable belt 1211 can be first controlled to extend by external force, so that the outer contour formed by the first part 111 and the second part 112 is larger than the patient's head contour. After that, after the head circumference mechanism 1 is placed in an appropriate position, the external force is slowly released, so that the retractable belt 1211 retracts, and the outer contour formed by the first part 111 and the second part 112 is reduced to fit the patient's head, that is, the installation of the head circumference mechanism 1 is completed. In addition, the retractable belt 1211 can also adopt other structures that can be extended under the action of external force and retracted after the external force is released, such as a clockwork structure, and the retractable belt 1211 uses the tension generated when stretched as a restoring force.

[0047] The charging mechanism 2 is used to charge the target component implanted in the patient's head, wherein the target component may be an implantable pulse generator. The charging mechanism 2 may include a shell 21 and a charging unit 22 disposed in the shell 21. The charging unit 22 may charge the target component implanted in the patient's head after being connected to a power source; for example, the charging unit 22 is a coil, and the charging unit 22 charges the target component by electromagnetic induction. The power source for powering the charging unit 22 may be disposed in the shell 21 and connected to the charging unit 22 through a control circuit; or, the power source for powering the charging unit 22 may also be a power supply device independent of the head-mounted wireless charging device, and the charging mechanism 2 may be provided with a power supply interface that passes through the shell 21, and the charging unit 22 is electrically connected to the power supply interface, and the power supply interface may be connected to the independent power supply device through a wire, so that the independent power supply device may supply power to the charging unit 22 in the shell 21 through the power supply interface.

[0048] The charging mechanism 2 can be movably connected to the head circumference mechanism 1, so that after the head circumference mechanism 1 is fixed on the patient's head, the charging mechanism 2 can be moved to adjust the position of the charging mechanism 2 to correspond to the position of the target component implanted in the patient's head, thereby allowing the charging mechanism 2 to be adapted to the position of the target component implanted at different positions on the patient's head through position adjustment.

[0049] The charging mechanism 2 can be connected to the head circumference mechanism 1 via the position adjustment mechanism 3 , and the relative position between the charging mechanism 2 and the head circumference mechanism 1 can be adjusted via the position adjustment mechanism 3 .

[0050] The position adjustment mechanism 3 may include a connector 33. One end of the connector 33 is connected to the charging mechanism 2, and the other end is slidably connected to the head circumference mechanism 1, so that the connector 33 can drive the charging mechanism 2 to slide relative to the head circumference mechanism 1. Specifically, the head circumference mechanism 1 is provided with a second slide groove 15, and one end of the connector 33 is arranged in the second slide groove 15, so that the connector 33 can slide along the second slide groove 15 relative to the head circumference mechanism 1. Among them, the second slide groove 15 can extend along the patient's body width direction. When it is necessary to adjust the position of the charging mechanism 2, the connector 33 can be controlled to slide in the second slide groove 15, thereby controlling the charging mechanism 2 connected to the connector 33 to move along the extension direction of the second slide groove 15. Among them, the connector 33 can be specifically connected to the charging mechanism 2 in a damped sliding manner, so that the charging mechanism 2 can slide relative to the connector 33, thereby adjusting the position of the charging mechanism 2. The connector 33 can achieve a damped sliding connection with the charging mechanism 2 through friction.

[0051] Among them, one end of the connecting member 33 connected to the head circumference mechanism 1 can be connected to the head circumference mechanism 1 through friction between the connecting member 33 and the head circumference mechanism 1, or through a damper to slide and damp the connecting member 33, so that the connecting member 33 can slide along the second slide groove 15 and can be locked in the second slide groove 15. In addition, the connecting member 33 can also be clearance-matched with the head circumference mechanism 1, and the head circumference mechanism 1 is connected to a fixing member, which can abut against the connecting member 33 to lock the connecting member 33, or separate from the connecting member 33 to release the connecting member 33; the fixing member can be provided with a thread, and the fixing member can be controlled by turning the knob to contact or separate the fixing member from the connecting member 33.

[0052] In some specific embodiments, the position adjustment mechanism 3 further includes a first adjustment knob 34, which is connected to the connecting member 33 and is used to control the connecting member 33 to slide along the second slide slot 15. Specifically, the first adjustment knob 34 is connected to the first gear member 35, and the first adjustment knob 34 is connected to the connecting member 33 and can drive the connecting member 33 to move synchronously. The head circumference mechanism 1 is provided with a first rack 36 extending along the extension direction of the second slide slot 15, and the first rack 36 cooperates with the first gear member 35 so that when the first gear member 35 is rotated, the first rack 36 limits the first gear member 35 from moving along its extension direction, that is, the extension direction of the second slide slot 15.

[0053] Example 2

[0054] like Figures 5 and 6 As shown, this embodiment is basically the same as Embodiment 1, except that:

[0055] The telescopic assembly 121 includes a telescopic portion 122 and an adjusting portion 123. The telescopic portion 122 is used to connect the first portion 111 and the second portion 112, and the adjusting portion 123 is connected to the telescopic portion 122 and is used to drive the telescopic portion 122 to extend or retract. When the adjusting portion 123 controls the telescopic portion 122 to extend, the distance between the first portion 111 and the second portion 112 increases, and the size of the inner contour formed by the first portion 111 and the second portion 112 increases; when the adjusting portion 123 controls the telescopic portion 122 to retract, the distance between the first portion 111 and the second portion 112 decreases, and the size of the inner contour formed by the first portion 111 and the second portion 112 decreases.

[0056] Among them, in order to facilitate adjustment, the adjustment part 123 can be arranged on the outer wall of the shell 21 of the head circumference mechanism 1, and the axis of the adjustment part 123 is perpendicular to the telescopic direction of the telescopic part 122. The adjustment part 123 can control the telescopic part 122 to extend or retract by rotation. For example, a helical gear is arranged at one end of the adjustment part 123 extending into the head circumference mechanism 1, and the telescopic part 122 adopts a telescopic rod structure that controls the telescopic extension by rotation. The telescopic rod that controls the telescopic extension by rotation has been widely used in the prior art, such as a threaded telescopic rod structure, so it is not repeated here. The telescopic part 122 is provided with another helical gear connected to the adjustment part 123. And the axis of the helical gear is perpendicular to the axis of the helical gear of the adjustment part 123. The adjustment part 123 and the telescopic part 122 are meshed by a pair of helical gears to realize the helical gear transmission, and then the rotation of the adjustment part 123 is transmitted to the telescopic part 122 perpendicular to its axis, and then the telescopic part 122 is controlled to rotate, extend or retract.

[0057] The position adjustment mechanism 3 includes a mounting member 31 extending in the width direction of the patient's body. The mounting member 31 can be fixedly connected to the head circumference mechanism 1, and after the head-mounted charging device is fixed to the patient's head, the mounting member 31 can be located on the top of the patient's skull. The charging mechanism 2 is sleeved on the mounting member 31 and is connected to the mounting member 31 in a damped sliding manner. Specifically, the charging mechanism 2 is provided with a through hole 23 for accommodating part of the mounting member 31, and the mounting member 31 can pass through the through hole 23 to achieve connection with the charging mechanism 2; and when the charging mechanism 2 moves along the extension direction of the mounting member 31, the through hole 23 can also avoid the mounting member 31, so that the charging mechanism 2 can slide relative to the mounting member 31. In addition, the charging mechanism 2 can achieve a sliding damping connection with the mounting member 31 through friction or a damper.

[0058] In some specific embodiments, the adjusting portion 123 can also be used to adjust the position of the mounting member 31, specifically, the position of the mounting member 31 along the patient's height direction, and the mounting member 31 is clearance-matched with the head circumference mechanism 1. In order to make the adjustment of the mounting member 31 and the telescopic portion 122 by the adjusting portion 123 not interfere with each other, the adjusting portion 123 can include a rotating portion 1231 arranged on the periphery and a pressing portion 1232 arranged inside. The rotating portion 1231 is sleeved on the pressing portion 1232 and is movably connected with the mounting portion, for example, the rotating portion 1231 and the pressing portion 1232 are damped by friction. One end of the rotating portion 1231 abuts against the head circumference mechanism 1 and is used to adjust the telescopic portion 122. The pressing portion 1232 can extend to the inside of the head circumference mechanism 1 and is used to control the position of the mounting member 31. Specifically, the pressing portion 1232 can be used to control the locking and release of the mounting member 31. For example, the pressing portion 1232 adopts an automatic pressing structure such as a ballpoint pen to drive a locking member to extend or retract. When the locking member extends to squeeze the mounting member 31, the mounting member 31 is fixed. When the locking member retracts to release the mounting member 31, the position of the mounting member 31 can be adjusted.

[0059] In some specific embodiments, the charging mechanism 2 includes a second adjustment knob 24, and the second adjustment knob 24 is used to control the position adjustment between the charging mechanism 2 and the mounting member 31. Specifically, the second adjustment knob 24 is connected to the second gear member 25, and the mounting member 31 is provided with a second rack 312 extending along the extension direction of the mounting member 31, and the second rack 312 can be engaged with the second gear member 25, and the second gear member 25 is driven to rotate by rotating the second adjustment knob 24, thereby causing the second gear member 25 to move relative to the extension direction of the second gear member 25, and at the same time, the second gear member 25 can drive the charging mechanism 2 to move along the extension direction of the second gear member 25. Therefore, by rotating the second adjustment knob 24, the charging mechanism 2 can be controlled to adjust the extension direction relative to the mounting member 31, that is, to adjust relative to the patient's body width direction.

[0060] Example 3

[0061] like Figures 7 and 8 As shown, this embodiment is basically the same as Embodiment 1, except that:

[0062] The head circumference mechanism 1 includes a first free end 13 and a second free end 14. When the first free end 13 and the second free end 14 are connected, the head circumference mechanism 1 forms a ring structure and is used to be mounted on the patient's head. By changing the connection position of the first free end 13 and the second free end 14, the size of the ring structure formed by the head circumference mechanism 1 can be adjusted, so that the head circumference mechanism 1 can be adjusted to an appropriate size according to the outer contour of the head of different patients.

[0063] The adjusting unit 12 is disposed on the first free end 13 and / or the second free end 14 , and the first free end 13 can be fixed at a plurality of positions of the second free end 14 through the adjusting unit 12 .

[0064] In some specific embodiments, the adjustment unit 12 includes a first connection portion 124 provided at the first free end 13 and a second connection portion 125 provided at the second free end 14. The first connection portion 124 can remain fixed at multiple positions of the second connection portion 125. For example, the first connection portion 124 includes at least one convex portion 1241, and the second connection portion 125 includes at least one concave portion 1251. Any convex portion 1241 can be matched with any concave portion 1251 to keep the first connection portion 124 and the second connection portion 125 fixed. By matching the convex portions 1241 at different positions in the first connection portion 124 with the concave portions 1251 at different positions, the connection position of the first free end 13 and the second free end 14 can be adjusted, thereby adjusting the size of the annular structure formed by the head circumference mechanism 1. In this embodiment, the first connection portion 124 includes a plurality of protrusions 1241 equidistantly distributed along the circumference of the head circumference mechanism 1 ; the second connection portion 125 includes a plurality of recesses 1251 equidistantly distributed along the circumference of the head circumference mechanism 1 .

[0065] In addition, the first connection portion 124 and the second connection portion 125 may also be other structures, for example, the first connection portion 124 and the second connection portion 125 are Velcro or buckles. Moreover, the adjustment unit 12 may be provided with only the first free end 13 or only the second free end 14, for example, the adjustment unit 12 is a hairpin structure, the hairpin structure is fixed to the first free end 13 or the second free end 14, and then after the first free end 13 and the second free end 14 are adjusted to appropriate positions, the first free end 13 and the second free end 14 are clamped and fixed by the hairpin structure.

[0066] The position adjustment mechanism 3 includes a mounting member 31 extending along the width direction of the patient's body, and a sliding member 32. The mounting member 31 can be fixedly connected to the head circumference mechanism 1, and after the head-mounted charging device is fixed to the patient's head, the mounting member 31 can be located on the top of the patient's skull. One end of the sliding member 32 is connected to the charging mechanism 2, and the other end is slidably connected to the mounting member 31, so that the charging mechanism 2 connected to the sliding member 32 can slide relative to the mounting member 31. Specifically, the mounting member 31 is provided with a first slide groove 311, and at least a portion of the sliding member 32 is arranged in the first slide groove 311, so that the sliding member 32 can slide along the first slide groove 311, and then the charging mechanism 2 connected to the sliding member 32 can slide along the extension direction of the first slide groove 311. Among them, the first slide groove 311 can extend along the width direction of the patient's body.

[0067] It should be noted that any of the head circumference mechanisms 1 in the above embodiments can be used in conjunction with the position adjustment mechanism 3 in another embodiment, without limitation. For example, the position adjustment mechanism 3 in which the connector 33 is slidably connected to the head circumference mechanism 1 in the embodiment can be used, and combined with the head circumference mechanism 1 including the first free end 13 and the second free end 14 in the embodiment 3 to form a head-mounted charging device.
