摘要:
Endoscopic biopsy forceps jaws having an outer edge which may be generally U-shaped, circular, or oblate circular are disclosed with teeth which extend completely around the outer edge. The teeth may take any of several arrangements. In a first arrangement, the teeth and valleys are formed with two substantially rectangular surfaces which meet at substantially horizontal vertex and nadir lines. In a second arrangement, each tooth has a vertex or peak located upward and inward from the outer edge, and is defined by a substantially triangular inner surface, a substantially quadrilateral base, and a surface which extends outward and downward from the vertex of the triangular surface to the outer edge of the jaw. Valleys between the teeth have two inclined surfaces which intersect along a line which extends inward and downward from the outer edge of the jaw. In a third arrangement, the peak of each tooth is defined by the vertex of a pyramid having four faces and valleys between these teeth have three substantially flat surfaces which intersect at a vertex which lies downward and inward from the outer edge of the jaw. Alternate embodiments of all arrangements include providing a lip around the outer portion of the outer edge so that the teeth and valleys are spaced farther in from the outer surface of the jaw cup.
