Thrust unit 1 has hollow holder which accommodates holders of clip unit 2 and pusher 4 and serves as holder of appliance. Section of this holder with operating part of 7-10 cm long, counting from its external edge is bent with respect to the remaining rectilinear section through 40-80 deg in plane perpendicular to clip application line. Holders of clip unit 2 and pusher 4 are made flexible for movement along curvilinear hollow of holder of thrust unit 1, for example, in the form of no-clearance roller transmission.
