摘要：
patent summary: "nerve block catheter". a nerve blocking catheter, wherein perivascular nerves may be effectively blocked, comprises: a plurality of electrodes, an improved tip structure； and a nerve block device. A catheter according to one aspect of the present invention is a nerve block catheter comprising: a long catheter body extended in one direction to have distal and proximal ends having an internal space formed in the longitudinal direction； a movable member capable of moving in the longitudinal direction of the catheter body in the internal space of the catheter body； an operating member from which the distal end is connected to the movable member to move the movable member； a plurality of support members from which the ends on one side are connected to the movable member, thereby allowing the other ends to be further away from or closer to the catheter body by movement of the movable member； a plurality of electrodes respectively provide at the other ends of the plurality of support members to generate heat； and conductive wires electrically connected to a plurality of electrodes, respectively, to provide a power source path for the plurality of electrodes, and comprising coil-shaped variable portions in which the proximal ends of the variable portions are attached to one side of the body of the electrode. catheter and distal ends of the variable portions are attached to the movable element.resumo patente de invenção: "cateter para bloqueio de nervo". um cateter para bloqueio de nervo, em que nervos perivasculares podem ser efetivamente bloqueados, compreende: uma pluralidade de eletrodos, uma estrutura de ponta melhorada； e um dispositivo de bloqueio de nervo. um cateter de acordo com um aspecto da presente invenção é um cateter para bloqueio de nervo compreendendo: um corpo de cateter longo estendido em uma direção de modo a possuir extremidades distal e proximal, tendo um espaço interno formado na direção longitudinal； um elemento móvel capaz de se mov
