    • The invention relates to a device and related method for sealing and/or dissecting body tissue using a reverse action instrument. The devices and methods described permit laparoscopic or natural body orifice access to an anatomical space and facilitate sealing portions of tissue together, dissecting tissue or combinations thereof. A surgical instrument for sealing and dissecting body tissue is described having distal and proximal ends with an elongated body. The body includes a jaw member positioned at the distal end that is defined by a stationary arm and a pivotable arm. A moveable closure sleeve is disposed at least partially about the body and the closure sleeve is configured such that coaxial movement of the sleeve along the longitudinal axis of the body causes the jaw member to open or close.
    • 本发明涉及使用反向作用器械来密封和/或解剖身体组织的装置和相关方法。 所描述的装置和方法允许腹腔镜或天然体孔进入解剖空间,并且有助于将组织的一部分密封在一起,解剖组织或其组合。 描述了用于密封和解剖身体组织的外科器械,其具有带有细长体的远端和近端。 主体包括定位在由固定臂和可枢转臂限定的远端处的颚构件。 可移动的闭合套筒至少部分地围绕主体设置,并且闭合套筒构造成使得套筒沿着身体的纵向轴线的同轴运动导致钳口构件打开或关闭。
