(c1. sap-ass) 3,084,433 Patented Apr. 9, 1963 2 scissors of FIG. 1 showing the opposite sides of the cut ting blades; FIG. 4 is a cross-sectional view through the wedging nose and cutting blades taken in the plane 4—4 of FIG. 2, and FIG. 5 is a fragmentary perspective view of the leading tip of the lower cutting blade and laterally extending lift ing nose. My invention relates to scissors or shears of the band Referring now particularly to FIG. 1, I have illustrated age~cutting type, and more particularly to an improved lifting nose or wedging structure enabling such scissors to 10 a bandage scissors comprising a pair of cutting blades 10, 11, each formed integrally with one of a pair of handle be used with greater effectiveness in cutting away very tight bandages without piercing a patient’s skin beneath the bandage. shanks 10a and 11a, respectively, and pivotally connected together for shearing action by a pivot pin 12. The pivot pin 12 is threaded into a tapped hole in the shank Conventional bandage shears or scissors are commonly provided with a discrete wedge-like nose portion ?xed t0 15 11a and is provided at its other end with a bolt head which holds the shank 10a in pivotal relation on the pin. the tip of the lower or entering blade and projecting appreciably forward beyond the tip of the upper blade. Since the cooperating cutting edges cannot extend beyond the tip of the shorter upper blade, the entire projecting From a point slightly forward of the pivot pin 12 the cutting blades 10 and 11 extend at similar obtuse angles with respect to their respective handle shanks 16a and nose, usually having a substantial length and thickness, 20 11a. At their rear ends the handle shanks are provided with ?nger rings 1% and 11b, respectively. must enter between the skin and the bandage before any As is customary with bandage scissors or shears, the cutting action can begin. For this reason the use of such cutting blades are considerably shorter than the handle shears with very tight bandages is often quite di?icult, shanks, for example about one-half the length from pivot painful or injurious to an incompletely healed wound. Accordingly, it is a general object of my invention to 25 pin to ?nger ring, in order to provide adequate mechan ical advantage for cutting heavy bandages. The blades provide an improved bandage scissors having a wedging 10 and 11 have planar inner surfaces arranged for ?atwise or lifting nose which does not extend forwardly beyond sliding engagement along a median shearing plane 13 the front tip of the cutting edges.

In my improved scissors, however, the cooperating cutting edges of the blades extend to the blade adapted for insertion between a bandage and the 45 upper blade. Whether or not the upper blade extends beyond the lower blade it should extend at least fully up skin of a patient. This lower blade is equal in length to to the leading tip of the lower blade (i.e. be of at least or slightly shorter than the overlying upper blade and is provide a wcdging bandage-lifting action. To improve this wedging action without interfering with shearing 50 action at the forward tip of the lower blade this blade carries at its tip a laterally extending wedging projection or lifting nose. This lifting nose is on the outer surface ably having a relatively wide and blunted forward tip which overlies the leading tip of the more pointed lower blade when the blades are in closed position. The lower scissors blade 10 is tapered in width from a point of maximum width near the pivot pin 12 to a narrow or pointed leading tip 15 which is only slightly ‘as best shown in FIG. 1.

In addition the nose 16 is my invention; FIG. 2 is a fragmentary plan view of the cutting blades, 70 tapered outwardly in a direction perpendicular to the shearing plane 13, preferably having a ?at upper surface, taken in the plane 2——2 of FIG. 1; or land 16a, substantially perpendicular to the shearing FIG. 3 is a fragmentary side elevational view of the 3,084,433 4 3 plane andrat the upper or_ shearing edge of the blade 10 claim to cover all such modi?cations as fall within the and tapering downwardly along the side of the blade 10 true ‘spirit and scope of my invention. to a narrow point at the lower edge of the blade. This What I claim as new and desire to secure by Letters Patent of the United States is: A bandage scissors comprising upper and lower cutting outwardly tapered shape (i.e. tapered in lateral cross section) is best shown at FIGS. 1, 4 and 5. It will now be evident that the lifting nose 16 is tapered in two directions, forwardly and outwardly, for a se blades pivotally connected together and having coplanar inner surfaces disposed for ?atwise sliding engagement in a common shearing plane, saidlower blade being tapered eration the lower blade 10 may be inserted directly under in width forwardly toward a bluntly pointed leading tip a bandage in a direction perpendicular to the edge of the 10 adapted for insertion beneath a bandage and both said bandage or may be inserted at an‘angle to the bandage blades having cooperating cutting edges in said shearing edge with the lateral lifting nose 16 foremost.
