Abstract: Surgical stapling instruments include mechanisms for identifying and/or deactivating stapler cartridge for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch for maintaining the locking member in the disabled position. The switch may be further configured to operate as a reload detection mechanism for determining the type of reload present in the surgical stapling instrument.

Abstract: Surgical instruments, such as clamping and cutting instruments, are provided. In one aspect, a surgical stapling instrument comprises first and second jaws and a drive member configured to move in a distal direction through at least one of the jaws. The instrument further includes a locking member movable between a first position permitting distal translation of the drive member, and a second position impeding distal translation of the drive member, and a switch movable from a proximal position to a distal position. When the switch is in the proximal position, it releasably maintains the locking member in the first position, and when the switch is in the distal position, it allows the locking member to move to the second position. This inhibits or prevents actuation of a knife when there is a spent or previously fired cartridge loaded in the instrument.

Abstract: Surgical stapling instruments include mechanisms for identifying and/or deactivating stapler cartridges for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch movable in a lateral direction to either maintain the locking member in the disabled position or to allow the locking member to move into the locking position. The instrument may further include a stapler cartridge including an annular pin configured to be engaged by a drive member at a an axial position to create a detectable resistance for reload detection by a control unit to identify the type of stapler cartridge present in the surgical stapling instrument.

Abstract: A surgical instrument includes an elongate shaft and an end effector. The end effector includes a jaw, and a coupling member configured to receive a first and second reload and to removably couple the first and second reload to the end effector. The coupling member is configured to retain the first reload in a closed position relative to the jaw such that the jaw and the first reload have a tissue gap therebetween. The coupling member is configured to retain the second reload in a closed position relative to the jaw such that the jaw and the second reload have a tissue gap therebetween that is larger than the first tissue gap. The instrument is designed to accommodate reloads with different tissue gaps between the first jaw and the reload, thereby allowing an operator to treat tissue of varying sizes, shapes and thicknesses with the same surgical instrument.

Abstract: Surgical clamping and cutting instruments are disclosed. In one aspect, a surgical instrument comprises an elongate shaft with an end effector having first and second jaws, a release member movably coupled to the end effector and a drive member configured to translate relative to the end effector. The instrument further includes a locking member movable from a first position permitting distal translation of the drive member, to a second position preventing distal translation of the drive member. The locking member moves into the second position after the drive member has been driven distally. This inhibits or prevents hazardous actuation of a knife or drive beam when, for example, there is a spent or previously fired cartridge in place.

Abstract: Drive assemblies for surgical clamping and cutting instruments, as well as surgical clamping and cutting instruments using these drive assemblies, are disclosed. The drive assemblies may include a drive member, a locking member mounted to the drive member, and a spring. The drive member may be configured to releasably engage at least one of a knife or a shuttle of a surgical clamping and cutting instrument for translating the knife and/or shuttle in a distal direction through a firing stroke. The locking member may be movable from a first position permitting distal translation of the drive member through the firing stroke, and a second position inhibiting distal translation of the drive member through the firing stroke. The spring may be configured to bias the locking member toward the second position.

Abstract: Locking assemblies for surgical clamping and cutting instruments include a locking member and a switch. A drive member may be configured to releasably engage a knife and/or a shuttle of the surgical instrument for translating the knife and/or shuttle in a distal direction through a firing stroke. The locking member is movable from a first position permitting distal translation of the drive member through the firing stroke, and a second position inhibiting distal translation of the drive member through the firing stroke. A switch, when proximally positioned, releasably engages the locking member to maintain the locking member in the first position. The switch disengages from the locking member when the switch is moved to a distal position.
