摘要： A forceps includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

摘要： An apparatus includes a body, a shaft assembly, an articulation section, an end effector, an articulation connector, and an articulation drive assembly. The shaft assembly extends distally from the body. The end effector is connected to the articulation section such that the end effector is configured to deflect relative to the longitudinal axis of the shaft assembly. The articulation connector is configured to translate relative to the shaft assembly to deflect the end effector relative to the longitudinal axis. The articulation drive assembly is configured to translate the articulation connector relative to the shaft assembly. The articulation drive assembly includes a rotatable housing and a first lead screw assembly. The first lead screw assembly includes a first half and a second half. The first lead screw assembly is slidably coupled with the shaft assembly and is configured to translate in response to rotation of the rotatable housing.

摘要： A stitching device includes a handle assembly and an elongate shaft assembly. The handle assembly includes a main rod and a drive conversion assembly including a cam wheel, a pivot block, first and second links, and a pawl. The pawl is operatively coupled to the main rod, and is configured to engage the pivot block to cause rotation of the pivot block which, in turn, causes reciprocating displacement of the first and second links. The elongate shaft assembly includes first and second blade drive members coupled to the cam wheel. The tool assembly includes first and second jaws and first and second blades. The first and second blades are operatively coupled with the respective first and second blade drive members, wherein axial displacement of the main rod transitions the first and second jaws between open and closed positions and causes reciprocating axial displacement of the first and second blades.

摘要： A forceps having a first jaw and a second jaw, where at least one of the first and second jaws is capable of moving between an open position and a closed positions. The forceps including an inner shaft located within an outer shaft and extending along the longitudinal axis, and a drive bar coupled to and extending distally from the inner shaft. The drive bar including a pair of drive bar struts extending from a distal portion of the inner shaft and positioned laterally inward of at least one of first and second set of flanges of the first and second jaws. A drive pin is securable to the pair of drive bar struts and the drive bar is translatable within the outer shaft to translate the drive pin to move the first jaw and/or the second jaw between open and closed positions.

摘要： A surgical kit includes a surgical stapling device and a loading assembly. The surgical stapling device includes a tool assembly and a buttress material. The tool assembly includes first and second jaw members. The first jaw member supports a staple cartridge that includes a retention assembly. The retention assembly includes a cam block including a pair of protrusions and a spring biasing the cam block towards the second jaw member. The buttress material includes proximal and distal portions. The proximal portion defines bores laterally spaced apart and configured to receive the pair of protrusions of the cam block. The distal portion defines a cavity to be placed over a distal end portion of the staple cartridge. The loading assembly includes a housing defining a chamber configured to receive a portion of the buttress material. The housing includes a proximal portion defining a slot configured to receive the buttress material therethrough and the pair of protrusions of the cam block.
