一种用于治疗青光眼的消融电极及消融主机 技术领域
本发明涉及医用器材技术领域，尤其涉及一种用于治疗青光眼的消融电极及消融主机。

优选的，作为消融主机的第二个实施例，如图6所示，手柄6内部设置有用于识别消融电极1型号的PCB电路板9。消融电极1与手柄6之间为可拆卸连接，消融电极1固定在手柄6上后，PCB电路板9用于对消融电极1的型号进行智能识别，消融主机自动配置相应消融电极1的型号参数，辅助医生操作，缩短手术时间。同时也能对消融电极1的寿命的智能识别，防止过期的消融电极1应用于手术中。
优选的，作为消融主机的第三个实施例，如图7所示，手柄6包括固定连接消融电极1的手柄头部61，即一个消融电极1对应一个手柄头部61；手柄6还包括连接尾线和通电插接件的手柄尾部62，手柄头部61与手柄尾部62之间通过插接的方式连接，即同一个手柄尾部62可以通过插接的方式连接不同类型的手柄头部61，这样能够方便在手术中更换不同型号的消融电极1。
手柄头部61内设置有用于识别消融电极1型号的PCB电路板9，PCB电路板9能够识别该手柄头部61内的消融电极1型号，并将该信息存储，辅助医生操作，缩短手术时间。同时也能对消融电极1的寿命的智能识别，防止过期的消融电极1应用于手术中。
由此可见，本发明公开了一种用于治疗青光眼的消融电极，包括位于消融电极中心的中心轴电极、套设在中心轴电极外围的绝缘套以及套设在绝缘套外围的外套电极；消融电极整体呈柱状，中心轴电极、绝缘套、外套电极同轴，消融电极通电后，中心轴电极与外套电极之间产生消融带，消融带用于作用于睫状体，减少房水的产生。本发明还提供一种用于治疗青光眼的消融主机，消融主机将消融能量传输至消融电极，消融电极经巩膜刺入睫状体内，消融主机输出射频消融能量传递到中心轴电极，能量电流经睫状体组织返回外套电极。消融电极产生的消融带破坏了睫状体的房水组织，进而减少睫状体内房水的生成，达到降低眼内压、治疗青光眼的目的。对于浅前房眼，经过消融电极消融后，可造成睫状体收缩，增加晶状体与睫状体之间的间隙，减少睫状体阻滞，降低跨晶状体压力差，加深前房。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
