Disposable surgical scissors

Claim 1

In a pair of scissors having a pair of handles pivotally connected together and cutting blades having cutting edges and mounted respectively on said handles, said cutting blades being pivotally movable into mutual contact along said cutting edges to close positions during a cutting operation, the improvement comprising: a. a mounting section on each of said blades, said mounting section including an arcuate edge configuration disposed generally between said cutting edges of said cutting blades, with said cutting blades being pivotally movable into mutual contact along their cutting edges to define an initial point contact immediately adjacent to said arcuate edge configurations; b. a camming section on each of said blades inclined and projecting from a corresponding mounting section and defining a relatively narrow camming surface and a relatively wide camming surface, said camming section of one of said cutting blades engageable with a mounting section of the other of said cutting blades to maintain a spacing between said mounting sections of said cutting blades thereby allowing sterilizing fluid or steam therethrough; c. stop means on said relatively wide inclined cam surface of each of said blades; d. said relatively narrow camming surfaces of said cutting blades being mutually overlapped and biasing said cutting blades towards each other to apply pressure at said initial point contact as said blades are pivotally moved into mutual engagement; e. said cutting blades being progressively pivotally movable slidably over each other to close position during a cutting operation and causing said point contact to traverse progressively along said cutting edges of said cutting blades in a direction away from said camming sections; f. said relatively wide inclined cam surfaces being mutually brought progressively into mutual slidable overlying relationship as said blades are progressively pivotally moved to closed positions during a cutting operation to bias said blades towards each other and to apply pressure at said traversing point contact during a cutting operation; and g. said stop means on each of said cutting blades being engageable on each other with said relatively wide inclined cam surfaces in overlying relationship thereby limiting further pivotal movement of said cutting blades beyond said closed portions.
