1. A hand clamp (100), comprising:
a dorsal arm (200) having a dorsal arm pressure plate (230) with a reference bulge, at least one close proximity bulge, and at least one distant bulge;
a palmer arm (300) having a palmer arm pressure bulge (320);
a biasing mechanism (500) engaging the dorsal arm (200) and the palmer arm (300) and is adjustable to create relative movement of the dorsal arm (200) and the palmer arm (300) thereby changing the distance between the palmer arm pressure bulge (320) and the reference bulge;
wherein;
a first position is defined by a minimum reference bulge first distance of 20 mm measured between the palmer arm pressure bulge (320) and the reference bulge, a second position is defined by a minimum reference bulge second distance of 18 mm between the palmer arm pressure bulge (320) and the reference bulge, and a reference bulge minimum distance delta is the difference between the minimum reference bulge first distance and the minimum reference bulge second distance;
a minimum close proximity bulge first distance is measured between the close proximity bulge and the palmer arm pressure bulge (320) in the first position, a minimum close proximity bulge second distance is measured between the close proximity bulge and the palmer arm pressure bulge (320) in the second position, and a close proximity bulge minimum distance delta is a difference between the minimum close proximity bulge first distance and the minimum close proximity bulge second distance;
a minimum distant bulge first distance is measured between the distant bulge and the palmer arm pressure bulge (320) in the first position, a minimum distant bulge second distance is measured between the distant bulge and the palmer arm pressure bulge (320) in the second position, and a distant bulge minimum distance delta is a difference between the minimum distant bulge first distance and the minimum distant bulge second distance;
the close proximity bulge minimum distance delta is less than the reference bulge minimum distance delta, and the distant bulge minimum distance delta is greater than the reference bulge minimum distance delta.
