摘要:
Described herein are specialized endoscopic drilling devices that may be readily powered by a conventional shaver handpiece and further may be utilized to secure a soft tissue graft to a boney surface. More particularly, the devices, systems and methods of the present invention enable the efficient and minimally invasive formation of off-axis sockets and/or tunnels in boney surfaces that may then serve as a site for graft placement by aperture and/or suspensory fixation means. As such, the present invention has particular applicability to the surgical repair and reconstruction of torn or ruptured tissues, such as ligaments and tendons, in the leg, knee and shoulder, for example.

Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply a precise amount of tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone, preferably while maintaining the requisite pre-determined suture tension and without introducing spin to the suture. Particularly preferred embodiments relate to multi-anchor constructs formed by. a. affixing at least one suture to the bone medial to the lateral edge of the soft tissue using a first implant, such as a cannulated knotless suture anchor, such that no portion of the implant lies lateral to the soft tissue edge; b. passing a first length of suture from the first implant over the soft tissue; c. forming a socket lateral to the edge of the soft tissue such that it is not underneath the soft tissue; d. establishing a desired tension in the first length of suture; and e. placing the implant in the socket so as to trap a portion of the first length of suture between at least a first portion of the implant and the wall of the socket so as to provide fixation. Multi-anchor constructs of the present invention may employ threaded implants exclusively, push-in implants exclusively, or a combination of threaded and push-in implants.

Herein described are suture-anchoring implanted medical devices formed from a bioresorbable metal alloy that may be used to secure soft tissue to bone. The metallic bioresorbable tissue anchoring devices of the present invention are optimally configured such that all portions of the device are resorbed over a short predetermined period of time while maintaining their tissue anchoring capability and preventing the generation of loose foreign bodies therefrom.
