| Abstract: |
An improved dental forceps has a pair of gripping distal tips for placing and removing articles such as metal bands, strips, and soft cotton pellets on and from teeth. A plane of orientation is defined by the longitudinal axes of two elongated legs which are biased apart from each other at one end when the legs are not being squeezed. At the end of each leg is a gripping distal tip, with both distal tips deviating at an angle from the legs' longitudinal axes toward the outside surface of one leg and away from the outside surface of the other leg, while staying approximately within the forceps' plane of orientation. Due to this planar orientation of the distal tips, less twisting of the wrist is necessary while using the forceps, thereby reducing the risk of radio-carpal conditions, especially after long periods of use. The distal tip of each leg has a curved inside surface such that the gripping space is formed between the surfaces when the legs are not being squeezed. Since the direction of forceps gripping is parallel to the forceps' plane of orientation, the major line of the gripping action is approximately contained across this plane. When the practitioner squeezes the forceps, the curled, inside edges of the distal tips exert a gripping action that produces a longitudinal or sliding motion between the distal tips as the practitioner varies the tightness of the squeezing action. The ability to effect this motion tends to increase sensitivity and fine control in gripping.

First Claim:
Show all claims |
1. A dental forceps comprising: a first leg and a second leg, each leg having an inside surface, an outside surface and a longitudinal axis; said longitudinal axes of said first and second legs defining a plane of orientation of said legs, each said leg terminating in first and second leg ends, said first leg end of said first leg in springing connection with said first leg end of said second leg, said second leg ends of said first and second legs being springingly biased apart from each other to place said forceps in an open position in the absence of pressure being applied on said outside surfaces of said first and second legs; each of said second leg ends on said first and second legs having a gripping distal tip oriented at an angle from the longitudinal axis of said legs toward said outside surface of said first leg and away from said outside surface of said second leg and approximately within said plane of orientation; and each distal tip having a curled inside surface; a gripping space existing between said curled inside surfaces when said forceps are in the open position; the simultaneous application of pressure on said outside surfaces of said first and second legs resulting in the squeezing of said first and second leg ends toward one another so as to cause a gripping action to be exerted by said curled inside surfaces of said distal tips as said forceps are placed in a closed position.
