  • Patent number: 11832815
    Abstract: A stapling device includes first and second jaws. The second jaw defines first and second threaded bores. A drive member has a distal end portion supporting a rack. An approximation drive assembly includes a first lead screw received within the first threaded bore. A second lead screw is received within the second threaded bore. A first pinion is supported on the first lead screw. A second pinion is supported on the second lead screw. Moving the drive member from the retracted position toward the advanced position advances the rack to rotate the first pinion and the second pinion, the first lead screw within the first threaded bore, and the second lead screw within the second threaded bore to move the second jaw in relation to the first jaw from an open position to a clamped position.

  • Publication number: 20230211126
    Abstract: A surgical instrument includes a housing (20), a syringe carriage (40), a movable handle (25), a shaft (30), a needle sheath (50), and a needle (60). The syringe carriage is operably coupled to the housing and configured to couple to a syringe. The movable handle is movable relative to the housing and operably coupled to the syringe carriage to distally advance the syringe carriage. The shaft extends distally from the housing and defines a lumen. The needle sheath extends through the lumen of the shaft, defines a lumen, and is movable relative to the shaft between an extended condition and a retracted condition. The needle extends through the lumen of the needle sheath and is configured to operably couple to a syringe coupled to the syringe carriage.

  • Patent number: 10758398
    Abstract: A guide apparatus for facilitating formation of a stoma includes a guide having an outer flange segment arranged about a central longitudinal axis and an insert segment. The flange segment is configured for engaging end margins of a body vessel extending through an opening in skin of a subject, and defines a plurality of apertures. The insert segment extends from the outer flange segment along the longitudinal axis. The insert segment is configured for at least partial positioning within the body vessel to maintain the patency of the body vessel. The guide apparatus further includes a plurality of fasteners for insertion within respective apertures of the flange segment of the guide. The fasteners are configured for penetrating the end margins of the body vessel extending through the opening in the skin to attach the end margins to the skin to thereby create a stoma.
