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

Low pressure rupture device
TL;DR: A safe pressure relief assembly of the reverse acting rupture disc type guards against very low pressure differentials and includes a thin, bulged sealing disc, a cutting member positioned in spaced relation to the sealing disc and extending a substantial transverse distance thereacross and a sealing disc support member having a stay arrangement projecting into supporting engagement with the concave side of the sealed disc as mentioned in this paper.
Patent
Variable force angle linkage
Gilbert F. Hyde,Ralph W. Legates +1 more
TL;DR: In this paper, a variable force angle linkage was proposed for actuating steam valves and the like, consisting of four linkages and characterized in that the force on a valve or other device was greatest when the valve was adjacent its seat, the force gradually diminishing as the valve moved away from its seat.
