Description
Technical field
The present invention relates to a kind of navigator, described navigator is used to produce a magnetic field, and described magnetic field is used for navigating to being admitted to the intravital medical apparatus and instruments with a magnet of a patient, and described medical apparatus and instruments is specific to be a capsule endoscope.
Background technology
When the patient being carried out expectant treatment or diagnosis, there are some known armarium in the prior art, these armarium can be admitted to (particularly in the hollow organ) in patient's body, and are navigated by different way.For example, when gastric mucosa was carried out routine examination, known way was will to send in the stomach through the endoscope of corresponding optimization by esophagus.This inspection can make the patient not feel well, and part patient also can feel pain, and in addition, it is on the scene that whole checking process all needs the doctor.
Therefore, the someone has proposed to be used for to sending into the replacement scheme that intravital medical apparatus and instruments navigates.These replacement schemes mainly are for described medical apparatus and instruments is equipped with a permanent magnet, so just can carry out corresponding navigation to this medical apparatus and instruments by a corresponding external magnetic field.With the gastric mucosa inspection is example, and conventional art recommend to use a capsule endoscope, fill water under one's belt after, by the patient this capsule endoscope is swallowed.Subsequently, this capsule endoscope swims on the water surface, and should control it along the line of vision of this capsule endoscope this moment by an external magnets, makes it carry out two dimensional motion on the water surface.In the process that water level under one's belt slowly descends, can be whole mucosa photographic map picture.
The at present used most volume of the navigator that produces suitable magnetic field is very big, and operation inconvenience, wherein, on the support a plurality of solenoids, particularly Helmholtz coil is installed.Another known way is that the patient is sent in the tubulose frame, and the same arranged around with magnetic resonance equipment of this tubulose frame has corresponding solenoid.The shortcoming of these embodiments of navigator is, equipment heaviness, not easy to operate not only, and the patient can not feel well in checking process yet, and in addition, its cost is also quite high.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of navigator that is used for the magnetic navigation medical apparatus and instruments, this navigator easy operating, volume is less, and cost is also lower.
According to the present invention, with regard to the navigator of the described type of introductory song, the solution of reaching this purpose is: be provided with particularly cylinder-shaped bracket of a tubulose, described support comprises at least three flat coils, described flat coil constitutes along circumferential extension and by a conductor that extends along a surface, and these flat coils are used for producing a controlling magnetic field that is basically perpendicular to the longitudinal axis extension of described support at described internal stent.
In view of the above, the present invention advises using smooth substantially flat coil, but not uses most cases lower volume solenoid bigger and with high costs.For example, so-called " fingerprint coil " a kind of flatwise coil that can be used within the scope of the present invention that comes to this.Wherein, be provided with a conductor of shape extension in the shape of a spiral.Certainly can use a loop coil that comprises an above wire turn, the conductor of this coil does not extend to coil central authorities yet.Adopting under the toroidal situation, this loop coil is corresponding arranges that along rack surface when this support was cylindrical or oval, this loop coil can bend easily.In the case, this toroidal wire turn is arranged side by side to small part on support.This coil is known as " drum winding " again.
In these flat coils, total total at least three flat coils that is to say that along circumferentially extending if this support is cylindrical, these at least three flat coils are located on the barrel surface of a bending on described cylinder-shaped bracket or in cylinder-shaped bracket.Can produce a controlling magnetic field at this internal stent by these flat coils.Wherein, can regulate (for example by a corresponding control device that is used to these coil current feeds), make this magnetic field be basically perpendicular to the longitudinal axis of this support this magnetic field.In view of the above, if one is in the patient's upper body that takes a seat posture and is surrounded by this tubular bracket, just can produce the magnetic-field component or the magnetic field gradient that extend along a horizontal plane.This point is advantageous particularly for the described floatation type capsule of introductory song, and this capsule can be directed at the effect lower edge of a uniform magnetic field component one line of vision, and carries out moving accordingly with the intensity of this magnetic field gradient under the effect of a magnetic field gradient that is produced.
Use low-cost flat coil not only can bring corresponding cost advantage, but also can dwindle the volume of described navigator, particularly its radial dimension.Make described navigator lighter whereby, volume is littler, thereby is easier to operation.
Wherein, the quantity along the flat coil of circumferential arrangement is not limited to three.Fact proved that four flat coils are the quantity of easy operating.In addition, for magnetic field can further being strengthened or improving the adjustability in magnetic field, also be provided with the flat coil that another layer at least radially is staggeredly arranged along described support.In the case, described flat coil be distributed in two-layer at least on.For example, under the situation that has four flat coils, two-layer flat coil can be set, wherein every layer of two flat coil.These flat coils can become several layers according to the mutual stacked arrangement of its make, but can not make the volume of described navigator become big.Described navigator still keeps basic compact structure.
Generally speaking, producing a controlling magnetic field that extends along described support y direction also is reasonably, that is to say, if be example with the above-mentioned patient of taking a seat, produces the controlling magnetic field that an in the vertical direction extends exactly.On navigator of the present invention, can reach this purpose by two kinds of designs, these two kinds of designs also can be adopted simultaneously.
