摘要： An end effector for a surgical instrument includes a fixed bearing member with mounting surfaces for attachment to a distal end of the surgical instrument. At least one jaw member of the end effector is configured to move relative to an opposing jaw member between open and closed configurations, and a force transfer member is configured for longitudinal motion with respect to the fixed bearing member. The force transfer member includes a pivot channel therein. The end effector also includes a reactive member coupled between the fixed bearing member and the at least one jaw member. The reactive member is constructed from a thin strip of conformable material and extends through the pivot channel such that relative longitudinal motion between the fixed bearing member and the force transfer member causes the reactive member to flex and the at least one jaw member to move relative to the opposing jaw.

摘要： A surgical instrument includes a housing, an end effector and an elongated shaft extending therebetween. The elongated shaft includes a distal portion that is movable between aligned and articulated configurations. A pair of drive cables extends through the elongated shaft and is coupled to the distal portion such that reciprocal longitudinal motion of the drive cables induces movement of the distal portion between the aligned and articulated configurations. An articulation drive mechanism is operable to induce reciprocal longitudinal motion of the drive cables. The drive mechanism includes an actuator and a pair of torsion members that are rotatable about two distinct axes in response to movement of the actuator. A respective follower is operatively coupled to each torsion member to translate in a respective longitudinal direction in response to rotation of the torsion members, and each follower is coupled to a respective drive cable to impart translational motion thereto.

摘要： An endoscopic surgical instrument includes an elongated shaft, which may be articulated to facilitate positioning of an end effector. The instrument accommodates reactionary forces associated with closing the end effector without substantial disruption to the position of the end effector. The instrument includes an elongated shaft housing generally defining distal and proximal shaft axes, and a torsion member extending through the shaft housing. The torsion member transmits rotational displacement from a handle portion of the instrument to the end effector to selectively move the end effector between open and closed configurations. The torsion member comprises a flexible shaft exhibiting a plurality of generally radial slots spaced longitudinally along a length of the flexible shaft.
