Abstract
The invention discloses a disposable composite ablation needle which comprises an ablation needle body and a ceramic shell wrapping the ablation needle body. A needle tip is arranged at the lower end of the ablation needle body. The needle tip is located outside the ceramic shell. The invention further provides an ablation propelling device which comprises the disposable composite ablation needle. By means of the design of ceramic outside and metal inside, the disposable composite ablation needle, like a traditional ablation needle, is free of needle breakage or deformation and higher in strength and increases the puncture surgery reliability.
Description
Technical field
The present invention relates to a kind of medical instruments field, specifically relate to a kind of disposable compound ablation needle.
Background technology
In the time of inside of human body generation pathology, and patient's health does not allow to perform the operation and cuts off treatment situationUnder, the means that sometimes need to utilize puncture to focus carry out biopsy or treatment (RF ablation, chemical ablation,Microwave ablation). What microwave ablation was applied in recent years is more and more extensive, and microwave refers to that frequency existsBetween 300MHz-300GHz, the frequency electromagnetic waves of wavelength between 1 meter (not containing 1 meter) is to 0.1 centimetre.Microwave also has duality principle as a kind of electromagnetic wave. The energy of microwave quantum is 199 × 10-25～1.99× 10-21 joule. Microwave magnetic field can make molecule high speed rotary motion temperature arrising caused by friction around, thereby makes groupKnit the necrosis of solidifying, dewater, reach the object for the treatment of.
Microwave ablation normally determines focus and skin anchor point by means of instrument as CT/MRI scanning meansOrientation and the degree of depth of puncture needle (ablation needle), the position of first measuring focus on the cross section of human body,In this aspect, select best inserting needle position and needle angle, utilize inserting needle aspect, needle angle and inserting needle darkThe three-dimensional conformation of degree determines the exact position of focus and puncture needle (ablation needle) inserting needle. Although CT/MRI sweepsImaging apparatus can be determined three-dimensional needle angle and depth of needle exactly, but the process of puncture operation be all byPatient carries out from CT/MRI scanning aspect shifts out, and in the time that patient leaves CT scan device, doctor can onlyAccording to the judgement of oneself, determine an inserting needle direction roughly, puncture, and then carry out CT scan and addTo confirm. While carrying out ablative surgery, skin entry point starts the tumour target spot that punctures after determining. Logical in punctureOften determine that by protractor needle angle and design puncture angle are consistent as much as possible, but practical operationIn journey, due to hand operation, often error is larger, and beginner is difficult to once successfully accurately sting accurate target spot. OftenIn piercing process, need repeatedly CT scan confirm and adjust the angle of puncture needle and the folder of human body fault planeAngle. Thereby operating time prolongation, patient irradiation dose are increased greatly. Owing to repeatedly puncturing and tumour target spotPuncture accuracy is poor and postoperative complication is increased, and directly affects result for the treatment of.
In addition, existing horseley-Clarke technique is difficult to be applied in the operation at other positions of human body, main causeThe soft tissue that is other positions of human body is unfixing with respect to skeletal tissue position around, makes image space and diseaseThe coordinate setting that people space is difficult to agree. Therefore the intervention at other positions of human body puncture is gone back neither one admittedlyFixed guide-localization/appearance device can be fixed up the direction of puncture needle, conventionally uses real-time CT imageGuiding, but due to the guiding location/appearance that do not puncture, still there is the blindness in piercing process, in doctor's handPuncture instrument does not have objective accurate position mark, is difficult in piercing process, puncture needle is fixed on pre-orbit determinationOn mark, can only rely on doctor individual's experience, need constantly carry out image scan and adjust direction, final result canCan or there is certain skew with desirable Planned Route, and time-consuming and affect result for the treatment of. In addition, CT scanShi doctor, with the hand steered puncture needle of holding, can suffer unnecessary radiation exposure.
Due to artificial many factors, usually cause inserting needle inaccurate, impact treatment precision. Sometimes need heavilyMultiple repeatedly inserting needle can cause wearing when serious by mistake, brings great misery and risk to patient. The more important thing is,Traditional ablation needle is metal material, and rigidity is strong, may occur broken needle or distortion, thereby lead when operationThe route that causes puncture departs from, and jeopardizes patient's life when serious can cause operative failure even time.
Therefore,, for above-mentioned technical problem, be necessary to provide a kind of intensity high, not yielding or fracture, pacifyDisposable compound ablation needle firmly entirely.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of disposable compound ablation needle, than traditional puncture needleIntensity is higher, can use safely, thereby improve the reliability of operation.
Concrete, for achieving the above object, the invention provides following technical scheme:
A kind of disposable use compound ablation needle, comprises ablation needle main body and is coated on ablation needle main body outsideCeramic package, described ablation needle main body lower end is provided with needle point, and described needle point is positioned at the outside of ceramic package.
Further, ablation needle main body top is provided with cooling water pipe, and the delivery port of cooling water pipe is positioned at ablation needleThe afterbody of main body.
Further, described ablation needle main body, ceramic package and needle point are structure as a whole.
On the basis of above-mentioned disposable compound ablation needle, the present invention also provides one to melt propulsion plant,Comprise the compound ablation needle of foregoing disposable use and the folder of the compound ablation needle of disposable use is installedTool.
Further, the compound ablation needle of described disposable use is provided with one or more.
Compared with prior art, beneficial effect of the present invention is mainly reflected in the following aspects:
1, the compound ablation needle of disposable use adopts the design of outside porcelain interior metal material, with traditional disappearingMelt pin and equate, there will not be broken needle or distortion, intensity is higher, increases the reliability of puncture operation;
2, can use fixture clamping melting on propulsion plant, ablation needle can directly be punctured to tumor locus,The fastness of propulsion plant is melted in guarantee;
3, there is the ablation apparatus microwave thermal field distribution of the compound ablation needle of disposable use even, concentration of energy,The thermal efficiency is high, and treatment time is short;
4, melt fast motion device multiple ablation needles can be set, multiple ablation needles can be worked simultaneously, can reach largerAblated volume.
