Abstract (en)

[origin: WO9602193A1] An end effector assembly (120) for use with an endoscopic instrument (10) includes a clevis (56) and first and second end effectors (58, 59). The clevis (56) has curved channels extending from a distal portion of the clevis towards the proximal portion of the clevis means. Each channel has first and second inner curved walls. The end effectors (58, 59) each have a proximally extending tang with first and second curved surfaces. The tangs of the end effectors are respectively disposed in the channels of the clevis (56), and are guided by the channels such that they are moved forward by a control member (16) of the endoscopic instrument (10), first curved surfaces of the tangs engage said first inner curved walls of the clevis to cause the end effectors to open. When the control member (10) moves the end effectors (58, 59) back, the second curved surfaces of the tang engage the second inner curved walls of the clevis which cause the end effector to close.
