Known surgical staplers include an end effector that simultaneously makes a longitudinal incision in tissue and applies lines of staples on opposing sides of the incision. The end effector includes a pair of cooperating jaw members that, if the instrument is intended for endoscopic or laparoscopic applications, are capable of passing through a cannula passageway. One of the jaw members receives a staple cartridge having at least two laterally spaced rows of staples. The other jaw member defines an anvil having staple-forming pockets aligned with the rows of staples in the cartridge. The instrument includes a plurality of reciprocating wedges which, when driven distally, pass through openings in the staple cartridge and engage drivers supporting the staples to effect the firing of the staples toward the anvil.
An example of a surgical stapler suitable for endoscopic applications is described in U.S. Pat. No. 5,465,895, entitled “SURGICAL STAPLER INSTRUMENT” to Knodel et al., which discloses an endocutter with distinct closing and firing actions. A clinician using this device is able to close the jaw members upon tissue to position the tissue prior to firing. Once the clinician has determined that the jaw members are properly gripping tissue, the clinician can then fire the surgical stapler with a single firing stroke, or multiple firing strokes, depending on the device. Firing the surgical stapler causes severing and stapling of the tissue. The simultaneous severing and stapling avoids complications that may arise when performing such actions sequentially with different surgical tools that respectively only sever and staple.
One specific advantage of being able to close upon tissue before firing is that the clinician is able to verify via an endoscope that the desired location for the cut has been achieved, including a sufficient amount of tissue has been captured between opposing jaws. Otherwise, opposing jaws may be drawn too close together, especially pinching at their distal ends, and thus not effectively forming closed staples in the severed tissue. At the other extreme, an excessive amount of clamped tissue may cause binding and an incomplete firing.
When endoscopic surgical instruments fail, they are often returned to the manufacturer, or other entity, for analysis of the failure. If the failure resulted in a critical class of defect in the instrument, it is necessary for the manufacturer to determine
.g. , endocutter, grasper, cutter, staplers, clip applier, entree device, drug / gene therapy rescue device, and energy device using sonography, RF, laser, etc .). 
 Known surgical stapler include an end effecter that simultaneously makes a longitudinal incision in tissue and applies lines of basic on opposing sides of the incision. The conclusion effector includes a couple of cooperating jaw members that, if the instrument is intended for endoscopic or laparoscopic applications, are capable of passing through a cannula passageway. One of the jaw member receives a staple cartridge having at least two laterally space rows of staples. The early jaw member specify an anvil having staple - forming pockets align with the rows of staples in the cartridge. The instrument includes a plurality of reciprocating wedges which, when driven distally, pass through openings in the staple cartridge and engage drivers supporting the staples to effect the firing of the basic toward the anvil.

A clinician use this device is able to close the jaw members upon tissue to position the tissue prior to firing. Once the clinician has determined that the jaw extremity are properly gripping tissue, the clinician can then fire the surgical stapler with a single firing stroke, or multiple fire strokes, depending on the device. Firing the surgical stapler causes severing and stapling of the tissue. The coincident severing and stapling avoids complications that may arise when performing such actions sequentially with different surgical tools that respectively entirely sever and raw material. 
 One specific advantage of being able to close upon tissue before firing is that the clinician is able to control via an endoscope that the desired placement for the cut has been achieve, including a sufficient amount of tissue has been get between opposing jaws. differently, opposing jaws may be drawn too close together, especially pinching at their distal ends, and thus not effectively forming shut staples in the severed tissue. At the early extreme, an excessive amount of clamped tissue may induce binding and an incomplete firing.
