ENDOSCOPIC BIOPSY FORCEPS JAWS

摘要

Biopsy forceps jaws (30) have a cup portion defined by a cup wall (32a) having an outer portion with a cup wall edge (32c), and an inner portion having teeth (40-49). The teeth (40-49) include peaks and valleys with the peaks rising above the outer portion cup wall edge (32c), and the valleys remaining below the outer portion cup wall edge (32c). When two opposed jaws (30) close, the peaks of the teeth (40-49) on one jaw (30) enter the valleys of the teeth (40-49) on the other jaw (30) and the edges (32c) of the cup walls (32a) of the two jaws (30) touch such that the teeth (40-49) of the two jaws (30) are fully enclosed by the outer portions of the cup walls (32a) and the outer surface of the closed jaws (30) is completely smooth.
