A device is provided, including a cutting rib, the cutting rib including an arcuate portion having an outer sharp edge and a centralizer configured to receive the cutting rib through a radial slot, the radial slot forming a gap with the cutting rib. The arcuate portion of the cutting rib is formed into a profile that follows a surface of the centralizer, the outer sharp edge of the arcuate portion of the cutting rib has a wavy profile that forms a tunnel in the gap between the centralizer and the cutting rib, and the outer sharp edge of the arcuate portion of the cutting rib protrudes outwardly from the surface of the centralizer. A method for using the device to cut bone in a surgical configuration is also provided.

An intramedullary bone fixation device that includes a shaft with a flexible region. The flexible region may be configured to flex from a first shape to a second shape as the shaft moves along a curved medullary canal. For example, the bone fixation device may include a distal bone screw that is configured to move along the curved medullary canal of first and second segments of a fractured bone (e.g., two segments of a broken rib) and fasten to the segment bone segment. The bone fixation device may include a locking member (e.g., a proximal bone screw) that is configured to lock the shaft to the first bone segment. For example, the shaft may be fixed to the distal bone screw and ratchetably coupled to the shaft such that the first and second bone segments can be compressed together by urging together the distal bone screw and the locking member.

The invention provides a device, a kit for repairing and fixing articular cartilage, and a method for the same. The device comprises a costal cartilage rod, an outer sleeve, a drilling part, and an auxiliary implantation component; the drilling part comprises a drill sleeve and a drill bit matching an inner diameter of the drill sleeve; the auxiliary implantation component comprises a cartilage rod sleeve and an auxiliary pushing element, the costal cartilage rod has a rod-shaped structure with a diameter ranging from 3 mm to 8 mm and less than an inner diameter of the cartilage rod sleeve, and the costal cartilage rod is obtained from processing of costal cartilage. The costal cartilage is selected from the group consisting of autologous costal cartilage, allogeneic costal cartilage, or xenogeneic costal cartilage. Costal cartilage is processed into a costal cartilage rod by using the device provided in the present invention.

The device of the present disclosure is configured for laparoscopic use, particularly to insert a fastener into a plate at an angle of up to 180° from the plane of insertion. The device is further configured to carry a plurality of fasteners, a tightening tool, a cutting device, and tweezers simultaneously to facilitate a rapid procedure while lessening the chance of infection by limiting the amount of times the device must be removed and re-inserted.
