Self-contained gas powered surgical stapler
TLDR
In this paper, a surgical stapler powered by a relatively low pressure gas supply contained in the staplers is described, which has a mechanical linkage between the pneumatic actuator and the staple driver with a differential mechanical advantage to match the substantially constant force provided by the pNE to the different forces required to first advance and then form the staple.Abstract:
A surgical stapler powered by a relatively low pressure gas supply contained in the stapler. The stapler has a mechanical linkage between the pneumatic actuator and the staple driver with a differential mechanical advantage to match the substantially constant force provided by the pneumatic actuator to the different forces required to first advance and then form the staple. This mechanical linkage allows use of a relatively small low pressure actuator and also substantially increases the efficiency with which the gas supply is utilized.read more
