摘要：
A surgical instrument, comprising: a housing (12)； an elongated rod (16) that includes a proximal portion coupled to the housing (12) and a distal portion opposite the proximal portion, the elongated rod (16) defining a longitudinal axis； an end effector (14) supported by the distal portion of the elongated rod (16), the end effector (14) being adapted to treat tissue and including a first and second jaw members (30, 32) pivotally coupled to move between the open and closed configurations, where each of the jaw members (30, 32) includes a pair of laterally separated tabs (30a, 30b, 32a, 32b), and where each of the tabs includes a surface of cam in it； a blade (102) that extends at least partially through the elongated rod (16) and is selectively movable in the longitudinal direction between the flanges (30a, 30b, 32a, 32b) of the jaw members (30, 32), being the blade blade (102) extendable towards a portion of the jaw members (30, 32) of contact with the fabric, and a drive rod (80) extending at least partially through the elongated rod (16) and which is selectively movable in the longitudinal direction with respect to the blade (102) and with respect to the elongated rod (16), the actuating rod (80) having a cam pivot (92) positioned to fit the cam surface of each one of the tabs (30a, 30b, 32a, 32b) to induce the jaw members (30, 32) to move between the open and closed configurations, substantially surrounding the drive rod (80) to the blade (102) by the four lateral faces to restrict the movim Blade breath in at least two orthogonal planes.Un instrumento quirúrgico, que comprende: un alojamiento (12)； un vástago alargado (16) que incluye una porción proximal acoplada al alojamiento (12) y una porción distal opuesta a la porción proximal, definiendo el vástago alargado (16) un eje longitudinal； un efector extremo (14) soportado por la porción distal del vástago alargado (16), estando el efector extremo (14) adaptado para tratar tejido e incluyendo un primer y un s
