Composite device for autologous bone harvesting and bone processing

A composite device for autologous bone harvesting and bone processing, comprising:

• a bone harvesting auxiliary device and a bone processing device, wherein
• the bone harvesting auxiliary device comprises:
• a bone harvesting caliper, comprising four caliper bars and four first knobs, each pair of the four caliper bars intersecting, and intersections being connected by the first knobs;
• wherein the first knob is configured to adjust a fastening degree between two caliper bars and to set and plan a bone harvesting area and size;
• a guide sleeve, comprising four ones, one end of each being connected to the first knob;
• and
• depth-limiting Kirschner wires, comprising four ones, and disposed inside the guide sleeve;
• the bone processing device comprises:
• a bone box, with a partition plate disposed in the middle, and a bone drawer disposed at the bottom, and the bone drawer being configured to collect a finished bone product,
• wherein a groove is provided on the partition plate;
• a fastening assembly, comprising a compression rod and a push rod, wherein the compression rod is disposed on a side wall of the bone box and extends into the interior of the bone box, and the push rod is disposed on a top surface of the bone box and extends into the interior of the bone box;
• a cutting assembly, comprising a rocker and a cutting blade, wherein one end of the rocker is disposed on a groove of the partition plate inside the bone box, and the rocker is located at an upper part of the bone drawer, the cutting blade is disposed on the rocker and is adjacent to an inner side wall of the bone box, and a length of the cutting blade is greater than a height of the bone box, so that the cutting blade has a lateral arcuate curvature;
• and
• a thread is provided on an outer side wall of one end of the rocker inside the bone box,
• wherein the bone drawer is an L-shaped structural connecting plate, one end of the bone drawer is parallel to a bottom surface of the bone box, and the other end of the bone drawer is parallel to a side wall of the bone box.
