Claims22
A tendon repair assembly for fixing a torn tendon to an attachment site on a bone, comprising:
- a bone engaging portion for engaging a portion of bone opposite the attachment site;
- a gap reducing portion comprising a hollow elongate portion including a tendon engaging member at one end defining a tendon engaging surface for pushing the tendon onto its attachment site;
- a first guide member for linking the bone engaging portion to the gap reducing portion, the bone engaging portion and the gap reducing portion being movable with respect to each other such that, in use, the tendon can be pushed onto the attachment site by the gap reducing portion while the bone engaging portion remains engaged with the portion of bone;
- a suture cartridge insertable into the hollow elongate portion to present a suture at the tendon engaging surface;
- and
- a bone piercing tool having two bone piercing elements, each bone piercing element having a hook formed therein adjacent to its tip;
- wherein the bone engaging portion includes a second guide member defining two parallel channels for guiding the two bone piercing elements in a direction towards the tendon engaging surface to engage the suture with their respective hooks.
