Erik Nelson - Santa Clara CA, US
Andrew J. McCarthy - Trabuco Canyon CA, US
Scott Zimmerman - Lancaster CA, US

International Classification:

A61B 17/072

Abstract:

A surgical stapling system can include a reload shaft. The shaft can include an elongate tubular member with have a jaw assembly at the distal end thereof and a coupling collar at the proximal end thereof. The shaft assembly also includes an articulation joint coupling the jaw assembly to the distal end. A drive member and an articulation member extend within the tubular body of the shaft from the proximal end to the distal end. A firing member is connected to the distal end of the drive member such that advancement of the drive beam advances the firing member to close the jaw assemblies and fire staples from a reload positioned in the jaw assembly. The shaft assembly can also include a lockout mechanism to prevent a firing operation on a previously-fired reload or no reload.

A61B 17/00
A61B 17/128
A61B 17/00

Abstract:

A laparoscopic clip applier can have a geared clip feed mechanism and a direct jaw clamping mechanism to provide smooth operation over a clip application stroke of a movable handle. The geared clip feed mechanism can include an idler gear and two drive gear racks to advance a feed slider feeding a clip to a jaw assembly. The two drive gear racks can be positioned to provide different gearing during clip feed and firing portions of the clip application stroke, allowing efficient packaging of the clip feed mechanism. A spring can rapidly withdraw the feed slider once the clip has been fed and before clamping begins. The movable handle can have a direct connection to a clamping slider to enhance user feedback during clamping of the clip. After clamping the clip, the movable handle can also assist in returning the clamping slider to an initial position for firing another clip.
