The invention discloses a water-cooling microwave ablation needle-shaped antenna, which comprises an ABS (acrylonitrile butadiene styrene) protection handle and an antenna rod body, wherein the ABS protection handle is connected with the antenna rod body. The water-cooling microwave ablation needle-shaped antenna is characterized in that the inside of the ABS protection handle is provided with a water inlet and outlet cavity and a minitype radio frequency coaxial connector; a shell of the ABS protection handle is provided with a microwave output indicator light and a control push button; the antenna rod body comprises an outer thin-wall casing pipe; and the inside of the outer thin-wall casing pipe is provided with a needle-shaped radiator cover, a radiator, a small-diameter coaxial cable and a cooling water inlet pipe. Compared with the prior art, the water-cooling microwave ablation needle-shaped antenna disclosed by the invention has the advantages of ultra-thin diameter, high intensity, high efficiency, high tolerance power, big ablation and damage range and good form, and the foundation is laid for the further tumor ablation therapy.
Description
Technical field
The present invention relates to medical apparatus and instruments, relate in particular to a kind of water cooling microwave ablation aciculiform antenna for tumour ablation treating.
Background technology
Tumor along with the progress of oncotherapy science, has obtained considerable progress in the tumor microwave ablation techniques medically be a difficult problem that is difficult to capture always clinically in recent years.Microwave ablation is to utilize the microwave energy effect to organize at once to produce heat effect, within several minutes time, forms the spherical thermal field of stable class, central temperature is greater than 100 ℃, the edge is greater than 60 ℃, tumor tissues at high temperature moment be solidified deactivation, and then progressively melt and reach therapeutic purposes.Because the safe and wound of microwave ablation technology is little, and controlled to the sphere of action size of tissue, so more and more be subject to doctors' high praise, the trend that becomes tumour ablation first choice of technology is arranged in the future.
Existing water-cooled microwave ablation needle shape antenna, because during high-power use, the operating temperature of front end irradiator (needle point place) is high, and but water-cooled can not useful effect arrive leading portion, the manufactured materials of at present aciculiform antenna use and technique all can not be born the microwave power up to 80W, thereby affect the emission of microwave energy, cause the scope that melts damage little, form is kept off sphere, exists simultaneously irradiator to puncture the security risk of damage.
In addition, there is defective in the design of aciculiform antenna front end radiator structure, standing-wave ratio large (SWR), and the delivery efficiency of restriction microwave power, simultaneously reflection power conference further causes the temperature of antenna outer surface to raise, and reduces water-cooled usefulness; The external diameter of aciculiform antenna is larger, and generally greater than 14G, the degree of normal tissue damage was high when clinical percutaneous puncture used; There are defective in front end intensity and the sharpness of aciculiform antenna, and resistance is large when causing puncture, a little less than the anti-twist ability, does not meet clinical actual requirement.
Summary of the invention
The present invention provides a kind of water cooling microwave ablation aciculiform antenna in order to solve the above-mentioned deficiency of prior art.
Above-mentioned purpose of the present invention realizes by following technical scheme: a kind of water cooling microwave ablation aciculiform antenna, comprise ABS protection handle and the antenna body of rod, ABS protection handle is connected with the antenna body of rod, it is characterized in that: described ABS protection handle inside is provided with turnover water cavity and miniature radio-frequency coaxial connector, ABS protection handle housing is provided with microwave output indicator and control knob, the described antenna body of rod comprises the thin-walled trocar sheath, is provided with aciculiform radiator cover, irradiator, thin diameter coaxial cable and cooling water inlet pipe in the thin-walled trocar sheath; Described aciculiform radiator cover, thin-walled trocar sheath and ABS protection handle are connected and fixed; irradiator, thin diameter coaxial cable are connected with miniature radio-frequency coaxial connector; between cooling water inlet pipe and the thin diameter coaxial cable outer wall; and the gap between cooling water inlet pipe and the thin-walled outer sleeve inner wall forms respectively inlet channel and water outlet; the rear end is connected with the turnover water cavity respectively, and the microwave output indicator is connected control line and corresponding adapter with control knob.
The present invention's advantage compared with prior art is: the present invention has ultra-fine diameter, and intensity is high, and efficient is high, tolerance power is high, melt the characteristics that the damage scope is large and form is good, for the progress of tumour ablation treating lays the first stone.
