Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to a kind of minimally invasive electromagnetism puncture localization needle.
Background technology
In Minimally Invasive Surgery, puncture needle can be used for opening operation path, since Minimally Invasive Surgery requires to be accurately positioned, otherwise
Correct diagnosis and treatment can not be made, therefore also require to be accurately positioned using when puncturing needle open channel,
It is positioned at present mainly by the experience of doctor or light guide tool, doctor leans on experience setting accuracy not
Height, the tool of light guide are mainly that the tip of calaculating apparatus determines the position at tip to the distance of positioning ball, are chased after so as to reach
The purpose of track；But since this instrument is easily deformed, once the tip location that tracks of deformation may with physical location have compared with
Big error.
In short, the precision of Needle localization is relatively low at present, the effect of operation is influenced.
Invention content
The present invention proposes a kind of minimally invasive electromagnetism puncture localization needle, and it is relatively low to solve Needle localization accuracy in the prior art
Problem.
A kind of minimally invasive electromagnetism puncture localization needle of the present invention, including：Puncture needle, magnetic seal wire and magnetic coupling, the magnetic
Property seal wire one end connection magnetic coupling, the other end be equipped with electromagnetic coil, it is described magnetism seal wire be sleeved on the puncture needle pluggablely
In, and cause after such insertion, electromagnetic coil is located at the tip of puncture needle, and the side wall at the puncture needle tip is equipped with through-hole.
Wherein, casing is further included, the electromagnetic coil of the magnetism seal wire and end is sealed in described sleeve pipe, the set
It manages and is sleeved on pluggablely in the puncture needle.
The minimally invasive electromagnetism puncture localization needle of the present invention is inserted into puncture needle, electromagnetism by that will carry the magnetic seal wire of electromagnetic coil
Electromagnetic coil is connected to electromagnetic equipment by connector by magnetic seal wire, to position the position of electromagnetic coil, so as to fulfill puncture
It is accurately positioned.
Description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also
To obtain other attached drawings according to these attached drawings.
Fig. 1 is a kind of minimally invasive electromagnetism puncture localization needle structure diagram of the present invention；
Fig. 2 is the enlarged diagram at (i.e. puncture needle tip) at dotted line round frame in Fig. 1；
Fig. 3 is the enlarged diagram at dotted ellipse frame in Fig. 1.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
The minimally invasive electromagnetism puncture localization needle of the present embodiment as shown in Figures 1 to 3, including：Puncture needle 1, magnetic seal wire 2 and electromagnetism
Connector 3, magnetic 2 one end of seal wire connect magnetic coupling 3, magnetic coupling 3 are connected by conducting wire 5, to access electromagnetic equipment, conducting wire
5 one end being connect with magnetic seal wire 2 are equipped with convenient hand-held Handheld Division 6.The other end of magnetic seal wire 2 is equipped with electromagnetic coil 4, magnetic
Property seal wire 2 be sleeved on pluggablely in puncture needle 1, and cause after such insertion, electromagnetic coil 4 is located at the tip of puncture needle, with facilitate
Position the position at tip.The side wall at 1 tip of puncture needle is equipped with through-hole 11, and magnetic seal wire 2, puncture needle 1 are taken out afterwards in place puncturing
It, can be to affected part injection medicament, such as mounted on the end of needle tubing：Operation consent injects anaesthetic in affected part, takes out and wears after the completion of puncturing
Pricker 1 cleans puncture needle 1 by through-hole 11.For through-hole 11 in the side at 1 tip of puncture needle, i.e. needle point is closing and placed in the middle,
Open more smooth during operation path rather than traditional syringe needle ramp type needle point, when inserting needle may slightly be hindered by lateral force
To soft tissue.
The minimally invasive electromagnetism puncture localization needle of the present embodiment by the magnetic seal wire 2 for carrying electromagnetic coil 4 by being inserted into puncture needle
1, electromagnetic coil 4 is connected to electromagnetic equipment by magnetic coupling 3 by magnetic seal wire 2, to position the position of electromagnetic coil 4, so as to
Realize that is punctured is accurately positioned.
Further, the minimally invasive electromagnetism puncture localization needle of the present embodiment further includes the electricity of casing 7, magnetic seal wire 2 and end
Magnetic coil 4 is sealed in casing 7, and casing 7 is sleeved on pluggablely in puncture needle 1.Casing 7 plays protection electromagnetic coil 4 will not
It is made dirty by blood or other body fluid, during cleaning, cannula cleaning 7 is more convenient.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
