Abstract
Abstract A pair of surgical scissors includes two levers pivoted about a center axis and extending alongside a first axis at right angles thereto and having a pair of finger loops at their ends remote from the pivotal center axis. Forming part of one lever and extending from the center axis along a second axis at approximately 45 degrees to the first axis is one of the scissor blades. Similarly extending from the other lever alongside the same second axis is the other scissor blade. Preferably, the second blade is substantially solid so that the space between the two axes is approximately filled with the second blade terminating in a sharpened edge arcuate about the center axis and also sharpened along the second axis as is the first blade.

A pair of surgical scissors comprising a first lever extending substantially alongside a first axis, a first finger loop on said first lever adjacent one end thereof, a second lever extending substantially alongside said first axis, a second finger loop on said second lever adjacent one end thereof, means substantially on said first axis and at the other end of said levers for pivoting said first lever and second lever together for relative rotation about a center axis, a first blade integral with said first lever adjacent said other end thereof and adjacent said first axis and extending substantially radially from said first axis along a second axis at an acute angle to said first axis, said second axis extending substantially through said center axis and being approximately co-planar with said first axis and disposed about 45 degrees therefrom, a second blade connected to said second lever adjacent said pivoting means and extending from said center axis alongside said first blade and along said second axis, meanS forming co-acting shearing edges on said first blade and said second blade, a web on said second lever substantially spanning the angle between said first axis and said second axis, and a cutting edge on said web arcuate about said center axis.
