Description
Technical field
This utility model relates to a kind of medical instruments field, is specifically related to a kind of disposable compound ablation needle.
Background technology
When inside of human body generation pathological changes, and the health of patient does not allow to carry out operation and cuts off treatment situation
Under, it is sometimes desirable to utilize puncture means focus is carried out biopsy or treatment (radio-frequency (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 exists
Between 300MHz-300GHz, wavelength 1 meter (without 1 meter) to 0.1 centimetre between frequency electromagnetic waves.
Microwave also has wave particle dualism 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 the temperature arrising caused by friction of surrounding, so that group
Knit solidification, dehydration necrosis, reach the purpose for the treatment of.
Microwave ablation determines focus and skin anchor point mostly by way of instrument such as CT/MRI scanning means
Orientation and the degree of depth of puncture needle (ablation needle), on the cross section of human body, first measure the position of focus,
In this aspect, select optimal inserting needle position and needle angle, utilize inserting needle aspect, needle angle and inserting needle deep
The three-dimensional conformation of degree determines focus and the exact position of puncture needle (ablation needle) inserting needle.Although CT/MRI sweeps
Imaging apparatus can accurately determine three-dimensional needle angle and depth of needle, but the process of puncturing operation be all by
Patient is carried out after CT/MRI scanning aspect removes, and when patient leaves CT scan device, doctor can only
According to the judgement of oneself, determine an inserting needle direction substantially, puncture, carry out CT scan the most again and add
To confirm.When carrying out ablative surgery, skin entry point i.e. starts to puncture tumor targets after determining.Puncture is led to
Often determine that needle angle keeps consistent as far as possible with design puncture angle by protractor, but practical operation
In journey due to hand operation often error relatively greatly, abecedarian is difficult to the most accurately sting quasi-target spot.Often
In piercing process, CT scan is needed repeatedly to confirm and adjust angle and the folder of human body fault plane of puncture needle
Angle.So that operating time extends, patient irradiation dose is greatly increased.Due to repeated localised puncture and tumor targets
Puncture poor accuracy and make postoperative complication increase, and directly affect therapeutic effect.
It addition, existing horseley-Clarke technique is very difficult to apply in the operation at other positions of human body, main cause
It is that the soft tissue at other positions of human body is not fixed relative to the skeletal tissue position of surrounding, makes image space and disease
People space is difficult to the coordinate setting agreed.Therefore the intervention at other positions of human body punctures and goes back neither one admittedly
Can be fixed up in the direction of puncture needle by fixed guide-localization/appearance device, generally use real-time CT image
Guide, but owing to not puncturing guiding location/appearance, still suffer from the blindness in piercing process, in doctor's hands
Puncture instrument does not has objective accurate position mark, is difficult in piercing process be fixed on puncture needle pre-orbit determination
On mark, need to can only constantly carry out image scan adjustment direction by the experience of doctor individual, final result can
Or can there is certain skew with ideal plan route, and time-consuming and affect therapeutic effect.It addition, CT scan
Shi doctor holds puncture needle with hand steered, can suffer unnecessary roentgenization.
Due to artificial many factors, often result in inserting needle inaccurate, impact treatment precision.Sometimes for weight
Multiple repeatedly inserting needle, can cause time serious wearing by mistake, brings the most painful and risk to patient.The more important thing is,
Traditional ablation needle is metal material, and rigidity is strong, it is possible that broken needle or deformation during operation, thus leads
Cause the route deviation punctured, when can cause operative failure even time serious, jeopardize the life of patient.
Therefore, for above-mentioned technical problem, it is necessary to provide a kind of intensity height, be unlikely to deform or fracture, pacifying
Complete firm disposable compound ablation needle.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of disposable compound ablation needle, wears than tradition
Pricker intensity is higher, can use safely, thus improves the reliability of operation.
Concrete, for achieving the above object, this utility model following technical scheme of offer:
A kind of single use is combined ablation needle, including ablation needle main body be coated on ablation needle body exterior
Ceramic 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 is arranged over cooling water pipe, and the outlet of cooling water pipe is positioned at ablation needle
The 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, this utility model additionally provides one and melts propelling dress
Put, be combined ablation needle including foregoing single use and installation single use is combined ablation needle
Fixture.
Further, described single use is combined ablation needle and is provided with one or more.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in the following aspects:
1, single use is combined ablation needle and uses the design of outside porcelain interior metal material, disappears with traditional
Melting pin to compare, do not have broken needle or deformation, intensity is higher, increases the reliability of puncturing operation；
2, fixture clamping can be used to melt on propulsion plant, ablation needle can with Direct perforantes to tumor locus,
Ensure to melt the fastness of propulsion plant；
3, having single use and be combined the ablation apparatus microwave thermal field distribution of ablation needle uniformly, energy is concentrated,
The thermal efficiency is high, and treatment time is short；
4, melting F.F. device and can arrange multiple ablation needle, multiple ablation needles are simultaneously operable, and can reach bigger
