Abstract

Clip forceps have a pair of clamp members each having a clamp portion and a handle portion extending from the clamp portion. The pair of clamp members cross each other so as to have an X-shaped configuration and are pivotally coupled together at their point of intersection. Grip portions extend from the respective handle portions so that the clamp portions can be moved toward and away from each other by moving the grip portions. Each of the grip portions is curved inwardly, has a semi-oval cross section and has a plurality of projections which provide the outer surface thereof.

Claims

1. Clip forceps for clamping clips, comprising:

a pair of clamp members each having a clamp portion, a handle portion extending from said clamp portion, and a grip portion extending from said handle portion, said clamp members crossing each other at a point of intersection so that the forceps has an X-shaped configuration, and said clamp members being pivotally coupled together at said point of intersection, the clamp portions and the grip portions being located on opposite sides of said point of intersection such that said clamp portions are movable toward and away from each other by moving said grip portions toward and away from each other, said grip portions constituting curved portions of said clamp members, respectively, that have outer surfaces that extend concavely inwardly toward one another as taken in the direction along the lengths of the grip portions, and convex inner surfaces that extend inwardly toward one another as taken in the direction along the lengths of the grip portions, each of said grip portions having a semi-oval cross-sectional configuration as viewed in a plane perpendicular to the length thereof, and each of said grip portions having a main body, a plurality of projections extending from said main body and which constitute the inwardly concave outer surfaces of the grip portions, and a stopper located at an end of the grip portion remote from the handle portion from which the grip portion extends, said stopper projecting outwardly of the outer surface constituted by the projections of the grip portion so as to prevent the forceps from slipping off one'"'"'s fingers when one'"'"'s fingers grip the forceps at said outer surfaces.

2. Clip forceps as claimed in claim 1, wherein said projections are dispersed over the entirety of the semi-oval cross-sectional configuration of the grip portions so as to prevent the forceps from slipping relative to one'"'"'s fingers as the grip portions are held in one'"'"'s fingers and the forceps is being turned with a twisting motion.
