TLDR
In this paper, a driving mechanism is provided as a means to clamp and implant surgical staples pneumatically, and a clamping piston is used to clamp the tissue and a driving piston is driven into position to implant the staples.Abstract:
A driving mechanism is provided as a means to clamp and implant surgical staples pneumatically. First, one pneumatic line propels a clamping piston to clamp the tissue and to propel a driving piston into position to be fired. Then a second pneumatic line causes the driving piston to propel a driver which implants staples into the tissue.read more

Surgical instrument and method
TL;DR: In this paper, the authors describe a surgical instrument useful for laparoscopic surgery comprising an insulated shaft, a control means and a connection to an electrosurgical radiofrequency power source, its distal end having a tissue-engaging ledge, and the shaft supporting a tissueengaging clamping or cutting member movable toward the ledge in response to the control means so that an artery or other tissue in the pocket of the J-hook can be clamped or cut while radiofrequency current is applied.
