Abstract

The invention relates to the technical field of ablation needles, in particular to an adjustable water-injection-type ablation needle with dual temperature sensors. The needle comprises a holding handle, an adjustment rotary knob installed at one end of the holding handle, an ablation syringe needle arranged at one end of the adjustment rotary knob and a cannula sleeving the outer wall of the ablation syringe needle. According to the adjustable water-injection-type ablation needle with the dual temperature sensors, the temperature of the ablation center area can be monitored through the temperature sensors arranged on the ablation syringe needle in real time, the temperature of the ablation edge area can be monitored through a thermocouple arranged on the cannula in real time, the definiteness of the ablation effect is conveniently and clearly judged, top rods drive a clamping sleeve to move, the position of the cannula installed in the clamping sleeve is changed, the position of the cannula on the ablation syringe needle is conveniently adjusted according to the shape of a tumor, so that the thermocouple on the cannula is adjusted to be located on the ablation edge area, the temperature of the ablation edge area can be controlled in real time, and ablation is conveniently conducted at the dangerous area.

Description

technical field [0001] The invention relates to the technical field of ablation needles, in particular to an adjustable double temperature sensor water injection ablation needle. Background technique [0002] Radio frequency is a high-frequency vibration with a frequency of 150,000 times per second. The human body is a complex structure composed of many organic and inorganic substances. The body fluid contains a large number of dielectrics, such as ions, water, colloidal particles, etc. The human body mainly relies on the movement of ions to conduct current. Under the action of high-frequency alternating current, the ion concentration change direction changes back and forth with the current direction as positive and negative half cycles. Under high-frequency oscillation, the ions between the two electrodes move rapidly along the direction of the electric force line, gradually changing from a moving state to a vibrating state. Due to the different sizes, masses, charges and...
