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.
