摘要： An applicator instrument for dispensing surgical fasteners includes a housing, an elongated shaft having a proximal shaft section and an articulating distal shaft section extending from the housing, a firing system disposed within the housing, an actuator that is engageable for commencing a firing cycle of the firing system, and an articulation lever provided on the housing for selectively articulating the articulating distal shaft section of the elongated shaft. The applicator instrument includes a cam plate disposed within the housing that is linked with the articulating distal shaft section and that coupled with the articulation lever for being rotated by the articulation lever between a first or horizontal position for straightening the articulating distal shaft section and a second or vertical position for articulating the articulating distal shaft section. An over-center assembly is coupled with the cam plate for forcing the cam plate into either the first position for straightening the articulating distal shaft section or the second position for articulating the articulating distal shaft section.

摘要： An applicator instrument for dispensing surgical fasteners includes an elongated shaft, a housing connected with the elongated shaft, a trigger, a gear train, and a firing system disposed in the housing. The trigger is squeezed for commencing a firing cycle. The firing system includes a storage reel, a spool connected to the storage reel, a drive wheel located distal to the storage reel and the spool, a constant torque spring having a proximal end connected to the spool and a distal end connected to the drive wheel, and a flexible member in contact with the drive wheel. The flexible member has a proximal end connected to the storage reel and a length configured to be driven by the drive wheel toward the distal end of the elongated shaft. During an energy storing stage, the gear train is coupled with the storage reel for rotating the storage reel in a counterclockwise direction, which, in turn, retracts and winds the flexible member onto the storage reel, which rotates the drive wheel in a counterclockwise direction and winds the constant torque spring from the spool onto the drive wheel for storing energy in the constant torque spring.

摘要： A method of dispensing surgical fasteners includes providing an applicator instrument having a housing with a cartridge opening, an elongated shaft extending from the housing, a firing system disposed within the housing for dispensing surgical fasteners, and an actuator for activating the firing system. The method includes forming a surgical opening in tissue, inserting a distal end of the elongated shaft into the surgical opening, inserting a cartridge containing a plurality of first surgical fasteners into the cartridge opening, and engaging the actuator for dispensing one of the first surgical fasteners from the distal end of the elongated shaft. While maintaining the distal end of the elongated shaft inside the surgical opening, the cartridge is removed from the cartridge opening, a second cartridge containing a plurality of second surgical fasteners is inserted into the cartridge opening, and the actuator is engaged for dispensing one of the second surgical fasteners from the distal end of the elongated shaft.

摘要： An applicator instrument for dispensing surgical fasteners includes a housing, an elongated shaft, and an elongated conduit extending through the elongated shaft. A firing system is disposed within the housing. The firing system has an insertion tool having a top surface that extends proximal and distal ends thereof and a stripper ramp that projects above the top surface. An actuator activates the firing system to commence a firing cycle. During the firing cycle, the firing system drives the insertion tool toward the distal end of the elongated shaft. The elongated conduit has a top wall with a top notch formed therein. The stripper ramp slides through the top notch for guiding movement of the insertion tool as the firing system drives the insertion tool toward the distal end of the elongated shaft.

摘要： An applicator instrument for dispensing surgical fasteners includes a housing having a cartridge opening, an elongated shaft extending from the housing, and a cartridge insertable into the cartridge opening, the cartridge having a plurality of surgical fasteners pre-loaded into the cartridge. The applicator instrument has a firing system disposed within the housing, and an actuator for activating the firing system to commence a firing cycle for removing one of the surgical fasteners from the cartridge and driving the removed surgical fastener from the housing to a distal end of the elongated shaft. In one embodiment, the cartridge includes a cartridge body having an upper end and a lower end insertable into the cartridge opening. The surgical fasteners are arrayed in a stack that extends between the upper and lower ends of the cartridge body. The cartridge has a constant force spring that normally urges the stack of surgical fasteners toward the lower end of the cartridge body for being fed into the firing system.
