Document Type and Number:
Japanese Patent JP6785059
Kind Code:
B2
Abstract:
A coupling device is provided for coupling a rod to a bone anchoring element, the coupling device including
a receiving part (5, 5', 5", 5"') having a first end (5a) and a second end (5b), a central axis (C) extending through the first end and the second end, a channel (52) for receiving a rod, wherein the receiving part defines an accommodation space (55) for accommodating a head (3) of a bone anchoring element (1), the accommodation space (55) having an opening (56) for inserting the head; and
a pressure element (6, 6', 6", 6") arranged at least partially in the accommodation space (55), the pressure element comprising a flexible portion (63, 63') to clamp an inserted head,
a clamping element (7, 7', 7", 7"') extending at least partially around the flexible portion (63, 63'), wherein the clamping element (7, 7', 7", 7"') is configured to move from a first position to a second position in which it exerts a clamping force onto the pressure element (6, 6', 6", 6"') and wherein the movement includes rotating the clamping element (7, 7', 7", 7"') around the central axis (C).
