Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a pelvic floor coil module for a pelvic floor magnetic stimulation therapeutic instrument. Background Art

[0002] Pelvic floor magnetic stimulation is an electromagnetic pulse acting on the pelvic floor neuromuscular tissue, generating nerve impulses to the peripheral central nervous system, causing the muscles it controls to contract. After treatment, it has the effects of tightening the pelvic floor muscles, relieving pelvic pain, inhibiting bladder detrusor contraction, and promoting blood circulation. Due to the complex structure of the pelvic floor, in order to obtain an induced electric field of sufficient strength in the lesion area to achieve neuromodulation, the stimulation current used in pelvic floor magnetic stimulation usually has a higher amplitude.

[0003] The Joule heat generated during the operation of the magnetic stimulation coil is the main source of heat for the pelvic floor magnetic therapy device. The resistance of the stimulation coil in the magnetic stimulation system cannot be ignored, and the heating problem of the stimulation coil is difficult to avoid during continuous operation. Once the heating of the stimulation coil exceeds the safety limit, the magnetic stimulation system must be suspended, which reduces the system's working efficiency, affects the stimulation effect, and even poses a safety hazard. In addition, the pelvic floor magnetic therapy device is heavy and is often inconvenient to move when treating some patients with limited mobility. Utility Model Content

[0004] The purpose of the utility model is to provide a pelvic floor coil module for a pelvic floor magnetic stimulation therapeutic apparatus, so as to solve the problem that the resistance of the stimulation coil in the magnetic stimulation system proposed in the above-mentioned background technology cannot be ignored, and the heating problem of the stimulation coil during continuous operation is difficult to avoid. Once the stimulation coil heats up beyond the safety limit, the magnetic stimulation system must suspend work, reducing the system working efficiency. In addition, since the stimulation coil is close to the human body, the stimulation effect is affected and there may even be safety hazards. In addition, the pelvic floor magnetic therapeutic apparatus is heavy and is often inconvenient to move when treating some patients with limited mobility.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pelvic floor coil module for a pelvic floor magnetic stimulation therapeutic instrument, comprising a shell, a boss fixedly connected to the surface of the shell, a magnetic stimulation coil abuttingly connected to the surface of the boss, a U-shaped magnetic core sleeved on the surface of the magnetic stimulation coil, cooling system connectors fixedly connected to both ends of the magnetic stimulation coil, the interior of the shell is filled with potting glue, a cover plate fixedly connected to the surface of the shell, a screw fixedly connected to the surface of the shell, a stepping motor connected to the surface of the screw by a thread, a support column fixedly connected to the bottom of the screw, a roller movably connected to the surface of the support column, and a roller fixedly connected to the surface of the roller.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Positioning the workpiece by setting a boss can maintain the accurate position and direction of the workpiece. The boss separates the outer shell from the magnetic stimulation coil and leaves a certain space to isolate the heat generated by the magnetic stimulation coil. By sleeved with a reasonably designed U-shaped magnetic core on the surface of the magnetic stimulation coil, the magnetic field focusing can be improved while reducing the resistance value of the magnetic stimulation coil, thereby reducing the Joule heat of the coil during operation. Through the cooling system connectors fixedly connected at both ends of the magnetic stimulation coil, when the equipment is working, deionized water flows into the inside of the magnetic stimulation coil under the action of the liquid cooling system, thereby taking away the Joule heat generated by the coil.

The interior of the shell 1 is filled with a potting glue 6, a cover plate 7 is fixedly connected to the surface of the shell 1, a screw rod 8 is fixedly connected to the surface of the shell 1, a stepping motor 9 is connected to the surface of the screw rod 8 through a thread, a support column 10 is fixedly connected to the bottom of the screw rod 8, and the surface of the support column 10 is movably connected to the support column 10. A roller 11 is connected, and a roller 12 is fixedly connected to the surface of the roller 11. The workpiece is positioned by setting a boss 2, and the accurate position and direction of the workpiece can be maintained. By sleeved with a reasonably designed U-shaped magnetic core 4 on the surface of the magnetic stimulation coil 3, the magnetic field focusing can be improved while the resistance value of the magnetic stimulation coil 3 can be reduced, thereby reducing the Joule heat of the coil during operation. Through the cooling system connector 5 fixedly connected at both ends of the magnetic stimulation coil 3, when the equipment is working, deionized water flows into the interior of the magnetic stimulation coil 3 under the action of the liquid cooling system, thereby taking away the Joule heat generated by the coil.

[0024] Furthermore, the boss 2 is cylindrical, and the boss 2 separates the housing 1 from the magnetic stimulation coil 3 and leaves a certain space. The boss 2 can position the workpiece, maintain the accurate position and direction of the workpiece, and isolate the heat generated by the magnetic stimulation coil 3.

[0025] Furthermore, the magnetic stimulation coil 3 is wound by a hollow copper tube and is in a U-shape, and the outside of the magnetic stimulation coil 3 is wound with insulating pressure-resistant material, which increases the heat dissipation capacity of the magnetic stimulation coil 3.

[0026] Furthermore, the U-shaped magnetic core 4 is U-shaped, and a groove is opened on the surface of the U-shaped magnetic core 4. The U-shaped magnetic core 4 is connected to the magnetic stimulation coil 3 through the groove. The U-shaped magnetic core 4 is reasonably designed to improve the focusing of the magnetic field while reducing the resistance value of the magnetic stimulation coil 3, thereby reducing the Joule heat during the operation of the coil.

[0027] Furthermore, the cooling system connector 5 is welded to both ends of the magnetic stimulation coil 3, and a circular groove is provided on the surface of the cover plate 7. The cooling system connector 5 passes through the circular groove and is fixedly connected to the cover plate 7. Through the cooling system connector 5, deionized water flows into the interior of the magnetic stimulation coil 3 under the action of the liquid cooling system, thereby taking away the Joule heat generated by the coil.

[0028] Furthermore, the potting glue 6 is composed of epoxy resin, and the shape of the potting glue 6 is consistent with the internal shape of the outer shell 1. The potting glue 6 completely fills the space between the outer shell 1 and the boss 2, the magnetic stimulation coil 3 and the U-shaped magnetic core 4. The internal space of the outer shell 1 is completely filled with the potting glue 6 to isolate heat, ensure the fixed position of the magnetic stimulation coil 3 and the U-shaped magnetic core 4, and make the magnetic stimulation coil 3 not easily deformed due to the magnetic field.

[0029] Furthermore, a groove 2 is provided at the bottom of the shell 1, the screw rod 8 is movably connected to the groove 2, the stepper motor 9 is fixedly connected to the groove 2, a round hole is provided on the surface of the roller 12, and the roller 11 passes through the round hole and is fixedly connected to the roller 12. Under the action of the stepper motor 9, the retractable function of the roller 12 is realized, and it is extended when needed and retracted when not needed. Under the action of the roller 11 and the roller 12, the pelvic floor magnetic stimulation therapeutic device is driven to move, and the patient can be treated more flexibly, which increases the use scenarios of the pelvic floor magnetic stimulation therapeutic device and enhances the functionality.

[0030] Working principle: Place the magnetic stimulation coil 3 and the U-shaped magnetic core 4 in the cavity inside the shell 1, fill the cavity with potting glue 6, connect the cooling system to the magnetic stimulation coil 3 through the cooling system connector 5, and connect the discharge circuit of the magnetic stimulation device to the magnetic stimulation coil 3 by wire welding. The U-shaped magnetic core 4 is sleeved on the surface of the magnetic stimulation coil 3, turn on the stepper motor 9, extend the roller 12, move the device to the specified position, turn on the stepper motor 9, retract the roller 12, and turn on the power. During the stimulation process, the magnetic stimulation coil 3 generates a pulse current, triggering a pulse magnetic field to complete the task of rehabilitation treatment. Heat will be generated after the device is powered on. At this time, deionized water flows into the stimulation coil under the action of the liquid cooling system, thereby taking away the Joule heat generated by the coil. The U-shaped magnetic core 4 will increase the inductance of the magnetic stimulation coil 3, which can correspondingly reduce the number of turns of the magnetic stimulation coil 3, thereby reducing the resistance of the magnetic stimulation coil 3, and the Joule heat during the working process will also be reduced.
