We reported the characteristics and usefulness of the disposable biopsy forceps (Radial jaw) from Microvasive Boston Scientific Corporation. Radial jaw has the tiny teeth around the cup and the wire with sheeth.
We biopsied the specimens from the antrum in stomach. We discussed the size and the damage of biopsied pathological specimens obtained by Radial jaw and the Olympus standard forceps. We also observed the slip of cup and bleeding tendency after biopsy by both forceps.
Radial jaw could biopsy 1.9 times larger specimens than standard. The damage of specimens was slight, and both of them were almost same level. Radial jaw was appropriate to perform the exact biopsy from oblique direction because of the cup form, and was useful of biopsy from long distance because of the sheeth. Bleeding tendency after biopsy was trivial in both forceps.
Recently many kinds of biopsy forceps are used, Radial jaw is suitable for upper GI examination.
