The stapler and staple cartridge described herein comprise those suitable for stapling a patient's mesentery and omentum with three or four rows of staples being substantially parallel to each other and the staples in one row being staggered with staples of the same size in another row, there being at least one row in which the staples differ in size from the staples in the other rows. Advantageously the larger staples are 30-50 percent larger, preferably about 33 percent larger than the smaller...

A stapling instrument including two elongate structural members each comprising a handle part with a jaw part projecting from a first end. The structural members have pivot means at second ends of their handle parts adapted for free engagement and disengagement and relative pivotal movement of the structural members between open and closed positions. An elongate locking member is mounted one one of the structural members for pivotal movement to a locking position generally aligned with its handl...

A surgical instrument for suturing blood vessels with U-shaped staples, has two supporting semibushes whose cylindrical surface has depressions for staples to be deformed, and two staple semibushes that embrace the supporting semibushes from outside so that an annular gap is left therebetween to accommodate the walls of the blood vessel being sutured. The staple semibushes are provided with radial slots, wherein staple-magazines are movably mounted; the magazines have staple recesses and staple ...

The end-to-end anastomosis surgical stapling apparatus is actuated in a single step. The apparatus includes a shaft which is able to pull the stapling anvil proximally in one step relative to a stationary housing as well as a plurality of circumferentially disposed balls mounted in cage-like manner in the housing which serve to lock the sleeve relative to the housing. The sleeve carries the staple cartridge and is released to move with the anvil when the anvil clamps the tissue against the cartr...

A stapler having a spine structure between a staple carrying head assembly and a manually operable actuator assembly that can be made either flexible or rigid as desired during use of the stapler.

In order to perform an anastomosis, a pilot head of a surgical staple suturing instrument is connected through a push-type or a threaded connector and through a paraboloid-like cap so as to simplify introduction into the organ that is to be anastomised. The combination body is pushed through the organ with the help of a probe, as far as the end of the organ that has been sutured with a purse-string suture. Once the desired position of the pilot head is reached, the cap is released and then remov...

A surgical microstapler is disclosed which does not require the use of a staple bending anvil that must be retracted after the staple is implanted. The surgical microstapler utilizes a stapler head comprising a staple magazine that consists of a series of staples attached to and supported by a plurality of frame members. The stables have a predetermined shape characterized by a spine portion and two opposite legs. The staples and frame members are formed as part of a sheet metal continuum and ar...

A surgical fastener apparatus possesses an improved fastener cartridge component. The cartridge includes a fastener holder pivotally connected to an anvil assembly, there being defined upon the opposed surfaces of said holder and anvil, gripping means for taking up the pulling and preventing or impeding such force from working against the fastener line.

The surgical stapling instrument is provided with an integral cartridge holders as well as a retaining pin and recess which serves to align the cartridge holder relative to the anvil while retaining the distal actuator bar from pivoting into an open position. In addition, the stapling cartridge is provided with four rows of staggered staples in order to provide a stapled seam through which blood is precluded from flowing.

An anvil and driver assembly for a surgical skin stapling instrument producing formed and implanted skin staples of more consistant and perfect configuration. The anvil provides an anvil surface which supports the crown of the staple during the forming operation. The driver has an inverted U-shaped notch formed therein which defines parallel side edges to bend the staple legs about the anvil and a transverse edge joining the side edges and adapted to contact the crown of the staple near the end ...
