摘要： 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.

摘要： 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.

摘要： 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.

摘要： The present disclosure provides a staple cartridge for a surgical instrument, such as a tissue sealing instrument. The staple cartridge includes a housing and one or more staple assemblies within the housing. The staple assemblies each include one or more staple pushers and associated staples. The staple pushers and housing include coupling elements configured to cooperate with each other to retain the staple assemblies to the housing prior to use in surgery. The coupling elements, along with other components of the cartridge and instrument, result in a smaller staple cartridge relative to conventional devices, allowing for a more compact and maneuverable surgical instrument.

摘要： The present disclosure provides a surgical instrument, such as a tissue sealing instrument, with an elongate shaft and first and second jaws movably coupled to the shaft. The second jaw comprises a cavity for receiving a staple cartridge and a substantially longitudinal reinforcing wall extending through the cavity. The instrument further includes a drive member configured to translate through the end effector to close the jaws and to engage a plurality of staples within the staple cartridge to drive the staples into tissue. The reinforcing wall provides additional support for the staple cartridge to inhibit deformation of the staple cartridge during actuation, thereby improving the staple formation in the tissue. This improves the tissue seal provided by the staples without increasing the overall size of the end effector.

摘要： 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.
