SUTURE ANCHOR AND DRIVER ASSEMBLY

摘要

An anchor (16) and anchor driver device (10) for securely and accurately positioning and installing a bone suture anchor (16) in place are disclosed. The bona anchor (16) preferably has a rounded or pointed head and one or more ridges (62) around it to help force fit the anchor into a hole and to hold it in place. A suture (18) is positioned through the anchor (16) for subsequent use during the surgical procedure. The driver device (10) has a handle (14) and elongated shaft (12) and is used to position and install the anchor in place. The anchor (16) snap fits onto the end of the shaft (12) over an anti-rotation pin (36) which mates with slots (38) in the anchor. A depth guide (70) can be positioned on the shaft to ensure correct depth of placement. Alternately, the driver shaft (104) is hollow and the anchor (110) is positioned inside it and implanted with a pusher member (114). The ends of the suture (18) can be affixed to the driver handle (14) to assist securing of the anchor (16) to the driver device (10) before and during insertion. Means (50) can be provided on the driver (10) to prevent the suture from interfering with the positioning and installation procedure.
