Description
Technical field
The present invention relates to field of medical device, can labelling puncture needle component in particular to one.
Background technology
Puncture needle is for penetrating into inside of human body, and extraction secretions is chemically examined in body cavity, or notes in body cavity
Enter gas or contrast agent carries out contrast examination, a kind of diagnostic equipment of injection of medicine again or in body cavity.Puncture needle usually with pin
Cylinder with the use of, in puncture needle being inserted into syringe during use and make syringe needle run through syringe, subsequently by puncture needle and syringe one
Rise penetrate into inside of human body, syringe can effectively the dilated penetration place of being needled into surrounding tissue.
In order to avoid penetration damage inside of human body is neural and tissue, puncture needle thrusts the angle of human body and the degree of depth all must be tight
The regulation followed in advance of lattice, but existing puncture needle is difficult to after entering human body carry out the most accurate location, extends hands
The art time, adding operating difficulty, orientation problem when therefore puncture needle uses annoyings medical worker always.
Existing puncture needle localization method mainly has ultrasonic locating, magnetic resonance location and X-ray development location.Wherein, super
The image that acoustic location method obtains is the fuzzyyest, it is impossible to the position of accurate positioning puncture needle.As Authorization Notice No. is
The patent of invention of CN101040790, it discloses a kind of puncture needle, and this puncture needle is had outside the tubulose of sword head by leading section
Cylinder pin and insertion combination are constituted at the interior pin of the interior intracavity of urceolus pin, and the periphery in urceolus pin region from sword head to cardinal extremity is implemented with
Recessed processing, interior pin starts the periphery in the region to cardinal extremity and implements coarse processing from front end.This puncture needle is filling with ultrasonic diagnosis
When puncturing in health under the observation put, it is possible to obtain until sword head end distincter by ultrasonic of puncture needle
The echo detection image of ripple diagnostic equipment detection.But the front end of the interior pin of this puncture needle starts outside the region of cardinal extremity
Implement coarse processing week, not only influence whether accuracy when puncture needle penetrates into human body, increase the probability of puncture needle skew,
Also can increase the misery of patient simultaneously.
The puncture needle that during magnetic resonance locating method imaging, metal material is made can produce artifact, affects the positioning accurate of puncture needle
Degree.If Authorization Notice No. is the patent of invention of CN101773404, it discloses a kind of magnetic resonance puncture needle, including outer pin and embedding
Enter the interior pin of outer pin；Outer pin includes outer pin handle and the outer casing needle being connected with outer pin handle, and interior pin includes interior pin handle and with interior
The interior nook closing member that pin is connected, outer pin handle is provided with hand-hole, and outer casing needle is provided with the mesopore communicated with hand-hole, and the external diameter of outer casing needle is less than
Hand-hole internal diameter；Interior pin handle includes outer end and the solid pin portion being connected with outer end, Gu pin portion is used for installing interior nook closing member, interior nook closing member
External diameter is less than outer casing needle mesopore internal diameter, and outer end abuts against with the end of outer pin handle；Magnetic resonance puncture needle also includes diamagnetism
Layer, diamagnetism layer is arranged on outer casing needle.It is big that this magnetic resonance puncture needle can only cut down puncture needle artifact under nuclear magnetic resonance
Little, artifact can not be removed completely.
During X-ray development location, after the puncture needle of steel enters into human body, when using x-ray scanning, puncture needle development is one
Bar straight line clearly, but owing to puncture needle can thrust human body along the arbitrarily angled of human body circumference, therefore develop according to puncture needle
The straight line obtained and the orientation of X-ray machine can not determine that puncture needle thrusts angle and the degree of depth of human body.Part puncture needle is in order to obtain
Preferable X-ray development locating effect, the needle body or syringe needle of puncture needle arrange projection, but the impact that these structures are serious
The accuracy in lancet puncture direction, makes skew during lancet puncture to be greatly increased, improves operating difficulty, simultaneously
Too increase the misery of patient.
Accordingly, it would be desirable to a kind of can in human body the puncture needle equipment of localised puncture angle and paracentesis depth accurately.
Summary of the invention
The invention provides one can labelling puncture needle component, it is possible to localised puncture is needled into the angle of human body fast and accurately
Degree and the degree of depth.
The present invention is achieved in that
One can labelling puncture needle component, including puncture needle and puncture needle the first pin being axially moveable can be sheathed on
Cylinder, the inwall of the first syringe is provided with axially spaced apart labeling section, puncture needle and labeling section and is made up of developing material, and first
Syringe is made up of not developing material, and wherein developing material can be developed by X-ray, and developing material is not developed by X-ray.
Further, this labelling puncture needle component can also include the second pin that can be sheathed on puncture needle and be axially moveable
Cylinder, the second syringe is made up of metal material.
Further, the inwall of the second syringe is provided with limiting section, and limiting section inserts the puncture needle of the second syringe for limiting
Move radially.
Further, limiting section includes at least two along the second axially extended lobe of syringe.
Further, the vertical sectional shape of labeling section is annular, in triangle, rectangle, trapezoidal, polygon or circle
A kind of.
Further, the distance between each labeling section is equal.
Further, at least one during developing material does not includes carbon fiber, plastics.
Further, at least one during developing material includes medical stainless steel, titanium alloy and Nitinol.
Further, puncture needle is made up of the first paragraph portion being alternately arranged vertically and second segment portion, and the pin of puncture needle
Point is first paragraph portion, and first paragraph portion is made up of developing material, and second segment portion is made up of carbon fibre material.
