Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] figure 1 The structure of a preferred embodiment of the foot pedal of the radiofrequency ablation apparatus provided by the present invention is shown.

[0021] The radio frequency ablation instrument provided by the present invention is the same as the existing radio frequency ablation instrument, and also includes a radio frequency ablation instrument main body and a foot pedal. What is different from the prior art is that the foot pedal is used to control the output size of the radio frequency current pedals.

[0022] Such as figure 1 As shown, the pedal includes an upper pedal 121 for stepping on and a lower pedal 122 for supporting the upper pedal. The upper pedal 121 and the lower pedal 122 are hinged by a fixed shaft 123 .

[0023] The pedal also includes a compression spring 124 disposed between the upper pedal 121 and the low...

Abstract

The invention provides a radiofrequency ablatograph which comprises a radiofrequency ablatograph body and pedal plates used for controlling the output number of radiofrequency currents. The pedal plates comprise an upper pedal plate used for being treaded and a lower pedal plate used for supporting the upper pedal plate, and the upper pedal plate is hinged to the lower pedal plate through a fixing shaft. The pedal plates further comprise an elastic component, and the upper pedal plate and the lower pedal plate are fixedly arranged at opposite positions through the elastic acting force of the elastic component. The pedal plates further comprise a variable resistor and a circuit used for communicating the variable resistor to the radiofrequency ablatograph body, and the position of the variable resistor is arranged as follows: when the upper pedal plate rotates around the fixing shaft and towards the lower pedal plate, the rotation of the upper pedal plate drives the resistance value of the variable resistor to be changed. A suction cup is further arranged on the bottom face of the lower pedal plate. The invention further provides a radiofrequency ablation system.

Description

technical field [0001] The invention relates to electrosurgery, in particular to a radiofrequency ablation instrument and a radiofrequency ablation system for denervating sympathetic nerves of renal arteries. Background technique [0002] Refractory hypertension, high blood pressure (sBP ≥ 160mmHg) that is difficult to control even after using more than 3 drugs (all of which have used a diuretic), is relatively common in clinical practice, with many pathogenic factors and unclear pathogenesis. Drug treatment The effect is very poor, and the diagnosis and treatment techniques are still immature, which has become one of the major problems in the treatment of hypertension. As a receptor of the central nervous system, the kidney will secrete more renin to activate the RAAS system under the action of the sympathetic nerve, causing a decrease in renal blood flow, resulting in water and sodium retention, and finally an increase in blood pressure; at the same time, the kidney acts a...
