Description
Technical field
The utility model belongs to Neural stem cell technical field, is related to a kind of Neural stem cell with circular coil and fixes device.
Background technique
Neural stem cell technology is that a kind of utilization circular coil that Barker et al. was proposed first in 1985 generates time-varying magnetic field
Cerebral nerve tissue is stimulated, generates induced current within the organization, the method for adjusting and interfering one kind of cerebral function new.Currently,
Neural stem cell is used for brain function research and various nerves and the new method in psychiatric system diagnosis and treatment as one, is treating weight
Degree depression, senile dementia, parkinsonism, insomnia and obsessive-compulsive disorder etc. have breakthrough progress.
In the design of magnetic stimulator, improving stimulus intensity, reducing device volume and reduce cost is magnetic stimulator trend
The important design goal in market.The size of the stimulus intensity of Neural stem cell and system discharge energy, discharge loop parameter (R, L, C)
Different values and the shape for the stimulating coil that discharges have direct relation.Capacitance in discharge loop depends on storage capacitor C value
Size, and the value of inductance L and resistance R in discharge loop depend primarily on Neural stem cell electric discharge stimulating coil inductance value,
The size of resistance value.Conventional Neural stem cell is to change C (storage capacitor) and U(discharge voltage) value change stimulus intensity.
However, improving stimulus intensity to reduce device volume, in the case where not changing C and U value, effective method is to change
The value of inductance L and resistance R in discharge loop, while the geometry of electric discharge stimulating coil need to be optimized.
The important carrier that stimulating coil is realized as Neural stem cell technology, the various parameter values of stimulating coil and stimulating coil
Shape all can intensity to induction field, boost pulse width and distribution have an impact.In order to improve the stimulating course of Neural stem cell
In stimulus intensity, stimulating coil is often made of multiturn conducting wire coiling in actual design.
Neural stem cell technology is different for stimulus intensity requirement in different experiments and clinical application, and stimulating coil
Different parameters value and shape directly affect stimulus intensity and magnetic pole focusing, for depth Neural stem cell, thorn
Sharp depth is a critically important technical indicator.The parameter value adjustability of stimulating coil affects the stimulation depth of Neural stem cell
Selectance.And the different parameters value of stimulating coil depends on the shape and the number of turns of coil made of coiling.Different shape and ruler
Very little stimulating coil is in experiment and clinical application, and for the safety and conveniently of user, problems faced is how solid
It is fixed, especially for the experiment and clinical application of different stimulated intensity, a kind of Neural stem cell line suitable for different sizes and the number of turns
The fixation device of circle seems critically important in the design of entire magnetic stimulator device.
Currently, circular coil as application upper comparative maturity one of pole coil, in various experiments and clinical application
Aspect achieves good achievement.But for a kind of round stimulating coil, it is fixed up in its parameter value and loop construction
Afterwards, coil discharge when space generate magnetic field size and distribution character decide accordingly.Therefore, it is filled to reduce
Volume is set, stimulus intensity is improved, under the value condition for not changing storage capacitor C and discharge voltage U, one kind is suitable for not
Same the number of turns, different internal-and external diameter the fixation device of Neural stem cell circular coil seem special needs, can not only save cost, but also can be with
It applies in the experiment and clinical application of different stimulated intensity, convenient for users to flexible combination use.
Summary of the invention
The purpose of the utility model is to provide one kind not only can guarantee operator's safety, but also is capable of fixing different inside/outside diameter sizes
The device of round stimulating coil.
To achieve the above object, the technical scheme adopted by the utility model is a kind of Neural stem cell is fixed with circular coil
Device, including top cover, internal diameter retainer plate, outer diameter retainer plate and pedestal, the side wall of pedestal are equipped with link block, install on link block
There is the handle of tubulose；Link block is equipped with the connecting hole that communicates with chassis interior, and one end of connecting hole and handle is affixed, handle
Inner hole is communicated by connecting hole with chassis interior, and the side wall of outer diameter retainer plate is equipped with opening, in use, outer diameter retainer plate and interior
Diameter retainer plate is placed in pedestal, and internal diameter retainer plate is located in outer diameter retainer plate, and internal diameter retainer plate and outer diameter retainer plate it
Between have gap, the opening on outer diameter retainer plate is connected to connecting hole.
The composition of the fixed device of stimulating coil is turned to 5 parts and processed by the fixed device of the utility model circular coil,
In the fixed dress of stimulating coil is being changed without for the stimulating coil of different the number of turns and different sizes (different stimulated coil internal-and external diameter)
In the case where the external structure set, fixed in difference by processing various sizes of outer diameter retainer plate and internal diameter fixed ring
The stimulating coil of outer diameter solves the fixation of the stimulating coil of different sizes and the number of turns, different parameters (R, L) value；It is logical
The fixed device of such Neural stem cell discharge coil is crossed, the reliability of system run all right is improved, ensure that the safety of operator
And convenience；For a set of magnetic stimulator, in the case where not changing energy storage device, make magnetic stimulating device for different rulers
The selection of the stimulating coil of very little, different the number of turns has more flexible selection, facilitates the experiment of different stimulated intensity requirement or faces
Application in bed.It is all practical for the coil of different the number of turns and outer diameter and in the case where internal coil diameter is constant, so as to
It is flexibly applied to experiment and the clinically requirement of different stimulated depth, improves the flexible of the circular coil selection of different model
Property, solve problems of the prior art.
