Abstract: A drawer locking mechanism for at least two drawers (6, 6') arranged one above the other has locking slides (13, 13') whose height is adjustable in a guide (7) along a setting axis (12). Setting elements (22, 22') with setting slots (29, 29') are attached with the slides between front panel (9, 9') of the drawer and the guide (7) arranged on the inner face of the side wall (2) of the body (1). Furthermore, the setting elements (22, 22') have two engagement regions which secure the setting elements (22, 22') in their respective angular positions corresponding to a pushed-in or pulled-out position of the drawers (6, 6'). Accordingly, control pins (31, 31'), associated with the side walls of the drawers (6, 6') as viewed from the front panels (9, 9') of the drawers (6, 6'), are positioned in front of the guide (7). Thus, the control pins do not have to pass the guide when the drawers are opened or closed, thereby improving utilization of space.

Abstract: A button for surgical applications comprising a disk having a slot which extends to a passage for guiding a thread therethrough within the circumference of the disk, said passage being sealed by a clamping device for clamping the thread firmly in the passage. The clamping device includes a disk segment movable parallel with the disk over the slot and passage to a latched position where its inner marginal part is past the passage thereby bending the thread and holding it by friction and compression.
