The present invention relates to an administration schedule comprising the intravenous administration of a -halogen-acryloyl distamycin derivative of formula . The legs are symmetrically arranged with respect to the center position of the spring member and each of the legs has a longitudinal axis and an end portion. The marks have a nominal dimension in the direction of the relative movement, and the field of view is larger than the nominal dimension. The driving force measuring part includes a first signal generating mechanism and a second signal generating mechanism. A method of forming a socket includes providing a flip retrograde cutter, inserting the cutter into a joint with a blade of the cutter in a straight position, pivoting the blade to a non-straight flip position, locking the blade in the flip position, and retrograde drilling a socket using the blade in the flip position. Batteries in the battery compartment may power the wheel and motor assembly after the switch is activated by a user.
