Miniature surgical forceps are formed from a one-piece tubular member by opposed longitudinal channels machined in a distal end thereof so as to establish a radially opposed pair of unitary forceps jaws. Most preferably, the opposed channels are formed in the distal end of the rigid tubular member by means of electron discharge machining (EDM) techniques. The resulting opposed cross-sectionally arcuate jaw sections may be bent and/or further shaped to achieve the desired final jaw configuration. The inner surfaces of the forceps jaws thereby established may have a filler material deposited in such a manner so as to change the overall shape and/or geometric configuration of the jaws and thereby engineer them to a specific surgical purpose.
A method of making miniature surgical forceps comprising providing a 19 gauge or smaller rigid tubular member, and removing material from longitudinal regions of a distal end of said tubular member so as to form respective longitudinally extending channels therein which thereby define an opposed pair of forceps jaws from respective remnants of said distal end of said tubular member.
A method of making miniature forceps comprising forming a radially opposed pair of proximally extending longitudinal channels in a distalmost end of a 19 gauge or smaller rigid tubular member to thereby establish an opposed pair of forceps jaws thereat, wherein said channels are formed by removing material from said distalmost end of said rigid tubular member.
