Abstract

A surgical forceps comprises two blades, each of which having a handle with a circular rest for fingers and a lock, and a jaw, incorporating a shank made integral with the handle, and a plate provided at the shank vacant end. A rectangular projection is provided on the flat surface of one of the blades, arranged along the plate longitudinal axis, and a slot with a concave bottom whose longitudinal axis is square with the longitudinal axis of the plate. A slit is provided in the plate of the other blade, arranged along the longitudinal axis of the plate, while its flat surface has an oval projection whose longitudinal axis is square with the longitudinal axis of the plate. The handles of the blades are so hinge-joined together that the afore-mentioned flat surfaces of the plates face towards each other.

Claims

1. A surgical forceps, comprising:

a first blade, incorporating;

a handle having a first end and a second end;

a circular rest for a finger, said rest being located at said first end of said handle;

a lock situated at said first end of said handle;

a jaw, comprising;

a shank having a first end and a second end, said first end being connected to said second end of said handle;

a rectangular plate having a longitudinal axis, a first end face and a second end face, a flat surface, a rectangular slit situated close to said first end face and arranged along said longitudinal axis of said rectangular plate, and a projection having a rectangular base, a convex surface, a height and a longitudinal axis, said projection being so arranged close to said second face that the longitudinal axis of said projection is square with the longitudinal axis of said rectangular plate, said second end face of said rectangular plate is connected to said second end of said shank;

a second blade, comprising;

a handle having a first end and a second end;

a circular rest for a finger, said rest being located at said first end of said handle;

a lock situated at said first end of said handle and adapted to interact with said lock of said first blade;

said second ends of said handles of said first and second blades hingedly joined together;

a jaw, comprising;

a shank having a first end and a second end, said first end being connected to said second end of said handle;

a rectangular plate having a longitudinal axis, a first end face and a second end face, and a flat surface that faces towards said flat surface of said rectangular plate of said jaw of said first blade, a rectangular projection having such geometric dimensions that are smaller than those of said rectangular slit of said rectangular plate of said jaw of said first blade, said projection being located on said flat surface nearby said first end face along said longitudinal axis, and a rectangular slot having a longitudinal axis and being congruent with said projection of said rectangular plate of said jaw of said first blade, said slot having a concave bottom and whose depth is smaller than said height of said projection congruent therewith, which slot is situated close to said first end face so that the longitudinal axis of the slot is square with said longitudinal axis of said rectangular plate.
