METHODS AND DEVICES FOR ATTACHING OR REATTACHING SOFT TISSUE TO BONE

摘要

Embodiments of the invention include implants, instruments, and methods for attaching or reattaching soft tissue (200, 2200) to a bone (100), that enable independent tensioning of multiple connectors such as sutures (60, 160, 2060, 2160) and enable redundant fixation between bone (100) and soft tissue (200, 2200). Some embodiments provide for improved accuracy of the placement of substantially parallel tunnels through which soft tissue (200, 2200) to bone (100) connectors such as sutures (60, 160, 2060, 2160) are passed.

主权项

1. An instrument set for creating two substantially parallel tunnels in a bone with a controlled distance and relative radial position between the two tunnels comprising:
a first instrument configured to create or maintain a first tunnel through the bone, the first instrument comprising:
a shaft with a proximal end and a distal end,a distal mark near the distal end of the shaft configured to designate a radial position of the first instrument, anda proximal mark near the proximal end of the shaft that correlates with the radial position of the distal mark; a drill guide with two or more radial indicia extending from a central hole, the radial indicia being configured to be aligned with the proximal mark to provide a radial direction for the creation of a second tunnel that is substantially parallel with the first tunnel, wherein two or more of the radial indicia include along their respective lengths a respective guide hole at a predetermined distance from the central hole; and a second instrument configured to be passed through at least one of the guide holes to create a second tunnel that is substantially parallel with the first tunnel.
