| Abstract: |
Disposable forceps are molded from a suitable sterilizable plastic material and they have a pair of arms joined together at inner ends by a hinge section of reduced cross-section so that outer sections of the arms are disposed substantially parallel to each other when the arms are in their normally inoperative position. When the arms are operated, the outer ends of the teeth engage before or simultaneously with the engagement of the innermost ends of the strengthening ribs. Alignment lugs are provided on an inside surface of each arm which have mateable surfaces to prevent any transverse misalignment between the teeth during engagement therebetween and outer ends of the alignment lugs engage recesses in the inside surfaces of the arms to prevent overstressing and rocking of the teeth.

First Claim:
Show all 6 claims |
The invention is claimed in accordance with the following:
1. In a forceps having a pair of elongated arms projecting longitudinally from a unitary connecting section, with tips adjacent to the free ends of said arms being engageable upon pivotal action of said arms toward each other, the combination comprising:
- a pair of diverging portions of said arms projecting longitudinally from said connecting section,
- a pair of elongated straight sections unitary with and projecting longitudinally from said corresponding diverging portions, each of said diverging portions including a first flexible hinge section of relatively thin cross-section immediately adjacent to the connecting section, each of said diverging portions further including a second relatively thick section unitary with and immediately adjacent to a corresponding flexible hinge section, said elongated arms being provided with corresponding elongated strengthening ribs, each of said ribs projecting laterally from and unitary with said relatively thick section and said elongated straight section of a corresponding arm, each of said ribs having a first end terminating at said relatively thin hinge section of a corresponding arm to prevent strengthening of said hinge section, each of said ribs having a second end projecting longitudinally beyond a free end of a corresponding arm to define one of said tips, and said tips of said ribs being provided with teeth, and said tips of said ribs being provided with teeth, which teeth are interengageable upon flexing of said hinge sections to allow pivotal action of said arms toward each other, said second ends of said ribs extending longitudinally beyond the free ends of said arms and being tapered to define said projecting tips.
