    • Bipolar electrosurgical scissors for treating biological tissue include first and second scissor blades. A shearing surface and cutting edge of each blade is electrically neutral. The scissors include a pair of electrical connections for receiving electrical currents of opposing polarities. Each blade includes at least one first electrode and at least one second electrode positioned on a surface opposite the shearing surface. The at least one first electrode on the first blade and the at least one second electrode on the second blade are coupled to the first electrical connection. The at least one second electrode on the first blade and the at least one first electrode on the second blade are coupled to the second electrical connection. In a first energized state, the electrical connections deliver electrical current only to the first electrodes. In a second energized state, the electrical connections deliver electrical current to all of the electrodes.
    • 用于治疗生物组织的双极电外科剪刀包括第一和第二剪刀刀片。 每个叶片的剪切表面和切割边缘是电中性的。 剪刀包括一对用于接收相反极性电流的电连接。 每个刀片包括至少一个第一电极和位于与剪切表面相对的表面上的至少一个第二电极。 第一刀片上的至少一个第一电极和第二刀片上的至少一个第二电极耦合到第一电连接。 第一刀片上的至少一个第二电极和第二刀片上的至少一个第一电极耦合到第二电连接。 在第一通电状态下,电连接仅将电流传送至第一电极。 在第二通电状态下,电连接向所有电极输送电流。

    • An insufflation gas warmer and humidifier apparatus and methods are provided. Insufflation gas is received from a bulky insufflation tubing. Insufflation gas received travels through, in one aspect, a channel or winding flow path, in a passage. The configuration of the passage ensures that the insufflation gas, which travels through the passage, receives sufficient heat and moisture. A humidifying reservoir humidifies the insufflation gas as the insufflation gas is passed to the passage. In one aspect, an oxygenator introduces slight amounts of oxygen into the insufflation gas. A warmer connected to the passage warms the gas in the passage. The warmer, in one aspect, contains a reactive agent that when exposed to air produces heat that is transferred to the passage to warm the insufflation gas within the passage.
    • 提供吹气加温器和加湿器设备和方法。 呼吸气体从大体积的吹气管接收。 在一个方面,接收的吹入气体在通道中行进通过通道或弯曲流动路径。 通道的构造确保了通过通道的吹入气体接收足够的热量和湿气。 当注入气体通过通道时,加湿储存器加湿注入气体。 一方面,氧合器将少量氧气引入吹入气体中。 连接到通道的温暖器会加热通道中的气体。 在一个方面中,温热器含有反应剂,当暴露于空气时产生热量,该热量被传递至通道以加热通道内的吹入气体。
