The new serrated-edge macro-morcellator (S.E. M.M.) enables the punching out of tissue cylinders up to a size of 10 x 1.5 cm diameter. If used together with a myoma drill, large holes can be punched into tumours, making them for the first time well palp-able and revolvable. With the help of needle hook bearers and an intracorporeal knotting technique it becomes possible, both to perform deep-seated sutures of muscles of the uterus, and one can use commercially available atraumatic suturing material with straight or hooked needles.
