摘要： A surgical instrument includes a handle assembly having a trigger (74) operable to fire a staple driver (24) to staple tissue. The instrument includes a pointed rod (38) to which an anvil (40) may be coupled. An anvil detection feature is included to determine when the anvil is coupled to the rod. In some versions, the anvil detection feature comprises a translatable rod (140, 230) that inhibits a lockout feature (82, 212) from disengaging. In other versions, an anvil sensing tube (622, 722)is disposed about the pointed rod and interferes with actuation of the trigger in a first position. A recess (624) in the tube permits trigger to actuate when the anvil sensing tube is in the second position. Alternatively, a resilient tab (310) is coupled to the pointed rod and resists actuation of the staple driver. A trigger lockout assembly (1300) may include a spring-loaded button (1352) that "pops" out when a push rod is actuated, thereby freeing a pivotable lockout feature.
摘要翻译：手术器械包括手柄组件，该手柄组件具有触发器（74），该触发器可操作以对钉钉驱动器（24）进行钉钉组织。该仪器包括可连接砧座（40）的尖棒（38）。包括砧检测功能以确定砧座何时与杆连接。在一些形式中，砧座检测特征包括阻止锁定特征（82,212）脱离的可平移杆（140,230）。在其它形式中，砧感测管（622,722）围绕尖的杆设置并且在第一位置上干扰触发器的致动。当砧感测管处于第二位置时，管中的凹部（624）允许触发器致动。或者，弹性片（310）联接到尖的杆并抵抗钉驱动器的致动。触发器锁定组件（1300）可以包括弹簧加载的按钮（1352），当推杆被致动时，弹簧加载的按钮“弹出”，从而释放可枢转的锁定特征。

摘要： An electrosurgical instrument can comprise a handle, a shaft, and an end effector, wherein the end effector can be rotatably coupled to the shaft by an articulation joint. The instrument can further comprise a drive member and the articulation joint can comprise flexible support members which can be configured to support the drive member. The instrument can further comprise supply wires electrically coupled to electrodes in the end effector and a wire tensioning device configured to prevent the supply wires from accumulating slack within the articulation joint. The drive member can comprise a plurality of flexible layers wherein some of the layers can be comprised of an electrically insulative material and other layers can be comprised of an electrically conductive material which is in electrical communication with a cutting member in the end effector and/or electrodes positioned within the end effector. A surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. The surgical instrument can further comprise a shaft extending between the handle and the effector and means for articulating the end effector relative to the shaft. The articulating means can comprise a portion of the shaft which is rotatable about a first axis in order to articulate the end effector about a second axis. In at least one embodiment, the shaft can comprise a first portion including a cam and a second portion including a cam follower, wherein the rotation of the second portion and the interaction of the cam and cam follower can cause the second portion to pivot relative to the first portion.

摘要： A bipolar electrosurgical instrument having a pair of relatively moveable jaws (22, 24) , each of which includes a tissue contacting surface. The tissue contacting surfaces of the jaws are in face-to-face relation with one another, and adjacent each of the tissue contacting surfaces are first and second spaced-apart electrodes (42, 44, 46, 48) that are adapted for connection to the opposite terminals of a bipolar RF generator. The first and second electrodes of one jaw are in offset opposed relation with the first and second electrodes of the second jaw. A cutting portion is provided between the jaws. The cutting portion (36) is moveable to provide the instrument with a scissors grasper capability. A tissue dam (656) is included on at least one jaw to help contain tissue within the desired coagulation area, and thereby help contain current density between the electrodes.

摘要： A surgical stapler (450) comprises an anvil assembly (100), an anvil shaft (104), a driver (62), an actuating arm (86), a safety switch (451, 851), and a safety feature (488, 888). The anvil assembly (100) couples with the anvil shaft (104). The driver (62)drives a plurality of staples into tissue. The actuating arm (86) is in communication with the surgical stapler and is configured to actuate the driver to drive the plurality of staples into tissue. The safety switch (451, 851) is moveable between a locked and an unlocked position. The safety switch prevents operation of the actuating arm when the safety switch is in the locked position. The safety switch enables operation of the actuating arm when the safety switch is in the unlocked position. The safety feature (488, 888) may prevent operation of the driver even when the safety switch is in the unlocked position or prevent operation of the safety switch.
