摘要： An ultrasonic ablation catheter comprises a catheter body (1), an ultrasonic treatment energy converter set (2), an ultrasonic imaging energy converter set (3), a control handle (4) and an energy converter interface (5). The catheter body (1) is of a cylindrical structure; the ultrasonic treatment energy converter set (2) is disposed on the lateral surface of the far end of the catheter body (1), is of a sheet shape or an unclosed ring shape and can emit line-shaped or subrounded ultrasonic beams. The crossing distance between every two adjacent ultrasonic treatment energy converters (21) is more than or equal to 1 cm. Each ultrasonic imaging energy converter (31) is positioned between every two adjacent ultrasonic treatment energy converters (21). The control handle (4) is disposed at the near end of the catheter body (1). The energy converter interface (5) comprises a first interface (51) and a second interface (52). After sympathetic nerve fibers are ablated by the ablation catheter, the nerve fibers can be cut into sections which are not continuous mutually and are completely separated in the middle; moreover, the coverage distance between the ultrasonic treatment energy converters (21) is long (more than or equal to 1 cm), so that mutual chemotaxis and self repair of the completely separated nerve fibers are avoided and stability of an effect of removing the sympathetic nerve fibers is improved.

摘要翻译： 超声波消融导管包括导管主体（1），超声处理能量转换器组（2），超声成像能量转换器组（3），控制手柄（4）和能量转换器接口（5）。 导管主体（1）为圆柱形结构; 超声处理能量转换器组（2）设置在导管主体（1）的远端的侧表面上，是片状或非闭合环状，并且可以发射线状或次要的超声波束。 每两个相邻的超声处理能量转换器（21）之间的交叉距离大于或等于1厘米。 每个超声波成像能量转换器（31）位于每两个相邻的超声处理能量转换器（21）之间。 控制手柄（4）设置在导管主体（1）的近端。 能量转换器接口（5）包括第一接口（51）和第二接口（52）。 交感神经纤维被消融导管消融后，神经纤维可以切成不连续的部分，并在中间完全分开; 此外，超声处理能量转换器（21）之间的覆盖距离长（大于或等于1cm），从而避免完全分离的神经纤维的相互趋化和自我修复，并且除去交感神经的作用的稳定性 神经纤维得到改善。
