Description
Technical field
The utility model belongs to the field of medical instrument technology, specifically, more particularly to a kind of capsule endoscope motion control
Magnetic means.
Background technology
Capsule endoscope is widely studied and is obtained for many years as a kind of method of effective diagnosis intestines problem
Rapidly development, at present, research and development have been no longer limited to enteron aisle diagnosis.
From the aspects of controllability, it is passive-type that capsule endoscope, which is divided into passive-type and active, traditional capsule endoscope,
Its movement in enteron aisle only relies on the intestines peristalsis of human body, and the motion state of capsule endoscope can not be controlled effectively, therefore can only be fitted
Answer the inspection of small intestine.Active to be also classified into internal drive and external drive and in the majority with external drive, major way is in capsule
Permanent magnet is added in inside, and motion control is carried out to it using the variation of external magnetic field.If active capsule endoscope can be in space
Larger examined area is effectively controlled, then the painless inspection of stomach and colon is also just possibly realized, then side of its control
Formula also becomes the hot spot of research in recent years.
The control mode of plain type is that doctor holds bar magnet with hand, is artificially carried out completely to the capsule in examinee's body
Control, such mode is easy, at low cost, but the operation for relying on very much doctor is horizontal, and omission factor is higher.Control external magnetic field movement
Or variation methods also occur it is a variety of, such as Siemens Company patent CN 201080038717.5, pacify writing brush photoelectricity skill
The patent CN 201310136094.0 of art company, they arrange magnetic field in the either above or below of examinee, and using automatically
Change equipment to control magnetic field.In both the above mode, the action of capsule dependent on the buoyancy of liquid in stomach, capsule dead weight and
The magnetic force three's that capsule is subject to balances, and capsule can theoretically be made to reach the state for suspending in liquid or being floated in liquid level.But
Be it is theoretic it is controllable be also in liquid level or following implemented, so examinee must be allowed to drink a large amount of clear water and alter one's posture
(lie low, lie on one's side, prostrate), human body significantly adjust posture, the factors such as uncontrollable of chamber portion, increase the possibility of missing inspection.
Utility model content
In view of the drawbacks described above of the prior art, the technical problem to be solved by the utility model is to provide in a kind of capsule
Mirror motion control magnetic means.
Technical solutions of the utility model are as follows：A kind of capsule endoscope motion control magnetic means, it is characterised in that：Magnet is
Multiple coil holders being distributed by even circumferential are arranged in circular ring shape in magnet, which is fixed on magnetic pole, each coil holder
On be both provided with coil, the root of the magnetic pole is mutually fixed with magnet.
Using above technical scheme, human body lies low in bed body, makes magnet and coil encircling in the periphery of human body.Coil with
Power supply connects, and by the way that current direction and size are powered and changed to coil, can change capsule endoscope as needed in alimentary canal
The direction for the magnetic force that any position is subject to and size make capsule endoscope can be moved into any position in examinee's alimentary canal, to
So that whole region of the capsule endoscope in alimentary canal inside and outside liquid level is all effectively controlled, makes examinee that need not repeatedly convert appearance
Gesture improves inspection efficiency, improves examinee's experience sense.
The root of the magnetic pole is swallow-tail form, and in the dovetail groove opened up on the root insertion magnet inner wall of magnetic pole, and by
The block of both sides limits, and the block is mutually fixed with magnet.The above structure magnetic pole installation operation is extremely convenient, and magnetic pole and magnetic
Body is connected firmly, reliably, will not occur to loosen or be detached from.
It is convenient for assembly in order to simplify structure, it is ensured that the fixing of installation, the coil holder is set on magnetic pole, and is passed through
Bolt is fixedly connected with magnetic pole.
For the ease of coil winding and positioning, annular groove is offered on the outer wall of the coil holder, coil is installed in the annular groove.
The magnet is located in the shell of circular ring shape, which is made of un-conducted magnetic material, one of magnet end face
Concordant with the corresponding end surface of shell, another end face of magnet is bonded with the annular convex platform in inner walls, and magnet and shell
Between be bolted.It is firm that the above structure housing is connect with magnet, convenient for disassembly and assembly, and passes through driving mechanism band dynamic friction
Wheel makes the inner wall of friction pulley and shell generate frictional force, to drive entire magnetic means to rotate, can not change size of current
And the magnetic force direction for making capsule endoscope be subject in the case of flow direction is rotated with magnet, and then the shooting direction of capsule endoscope is made to occur
Change, because electric current need not be changed at any time so that inspection becomes easier.
Preferably, the shell is made of aluminium alloy.
Advantageous effect：The utility model is simple in structure, and parts are few, and assembling is easy, and production cost is low, by logical to coil
Electricity simultaneously changes current direction and size, can change the side for the magnetic force that capsule endoscope any position in alimentary canal is subject to as needed
To and size, so that whole region of the capsule endoscope in alimentary canal inside and outside liquid level is all effectively controlled, keep examinee more
It is secondary to alter one's posture, inspection efficiency is improved, examinee's experience sense is improved, avoids the possibility of missing inspection.
Description of the drawings
Fig. 1 is the structural schematic diagram of one specific implementation mode of the utility model.
Fig. 2 is the A-A sectional views of Fig. 1.
Specific implementation mode
