Abstract: A low-profile offset-type spinal fusion device includes a first screw, a connection base, a nut and a compression part. The first screw has an external thread and a flange. The connection base includes a penetration part and a connection part disposed no higher than the penetration part, and can sleeve the first screw through a first hole of the penetration part to contact the flange with opposite ends of the first screw protruding out of the first hole. The nut, used to engage the first screw, has a bottom surface to contact against the penetration part. When the first screw is installed by penetrating the first hole, the nut and the flange are located to opposite ends of the first hole. The compression part is to screw into a cavity of the connection part for depressing a connecting bar tightly in the cavity.

Abstract: A cartilage repair implant, an auxiliary surgical tool kit and a cartilage repair system are provided. The cartilage repair implant includes a body and a plurality of pins. The body is a porous structure and is configured to carry cartilage repair material. The pins are fixed to the body for being inserted into a patient's bone. The auxiliary surgical tool kit includes a positioning sleeve and a click tool. The positioning sleeve has a through passage. A first alignment structure is disposed on the sidewall of the through passage. The click tool includes an outer tube and a push rod. A second alignment structure mutually aligned with the first alignment structure is disposed on the outer wall of the outer tube. The outer tube is configured to pass through the through passage. The push rod is slidably disposed in the outer tube. One end of the outer tube has a shaping blade for slicing a to-be-implanted region on an affected area of the patient. In which the shape of the to-be-implanted region is corresponding to the shape of the body.

Abstract: The disclosure relates to a spinal intervertebral body fusion device including an adjustable spacer, a first and second pushing piece, and an operative piece. The adjustable spacer includes a first and second supporting plate. The first supporting plate portion is movably installed on the second supporting plate portion. The first and second supporting plate portions form a first and second opening respectively located at two opposite sides of the adjustable spacer. The first pushing piece located at the first opening and is partially clamped by the first and second supporting plate portions. The second pushing piece located at the second opening is partially clamped by the first and second supporting plate portions. The operative piece is movably disposed through the second pushing piece and screwed to the first pushing piece. The operative piece has an annular slot, and the second pushing piece is partially located in the annular slot.
