摘要： A method for treating a bone body comprises inserting a probe having at least one active electrode into the target tissue and applying a voltage difference between an active electrode and a return electrode to ablate the tissue. The method is particularly directed to removing tumors in a bone body and or removing cancellous bone in a bone body. The bone body may be a vertebral body. The devices include electrosurgical probes which enable their electrodes to access tissue at trajectories beyond that of the access channel through which they are delivered to the target tissue. Also, a kit includes an electrosurgical probe, an electrosurgical generator, an introducer needle, and a fluid connector to connect the introducer needle to a fluid source such that liquid may be supplied to the target tissue during an application.
摘要翻译：一种用于治疗骨体的方法包括将具有至少一个活性电极的探针插入目标组织中，并在活性电极和返回电极之间施加电压差以烧蚀组织。该方法特别涉及去除骨骼中的肿瘤和/或去除骨体中的松质骨。骨骼体可以是椎体。这些装置包括电外科探针，其使得它们的电极能够在比通过它们被传送到目标组织的进入通道的轨迹处访问组织。而且，套件包括电外科探针，电外科发生器，导引针和流体连接器，以将导引针连接到流体源，使得液体可以在施用期间被供应到靶组织。

摘要： A method for treating a bone body comprises inserting a probe having at least one active electrode into the target tissue and applying a voltage difference between an active electrode and return electrode to ablate the tissue. The method is particularly directed to removing tumors in a bone body and or removing cancellous bone in a bone body. The bone body may be a vertebral body. An apparatus includes a plurality of active electrodes and a distal section including two bends. The bends serve to prevent the active electrodes from impinging upon the shaft of an introducer needle. Also, a kit includes an electrosurgical probe, an electrosurgical generator, an introducer needle, and a fluid connector to connect the introducer needle to a fluid source such that liquid may be supplied to the target site during an application.
