Sawing-punching integrated preparation device and method for decellularized bone regeneration and repair material

Abstract

The invention discloses a sawing-punching integrated preparation device and method for a decellularized bone regeneration and repair material. The sawing-punching integrated preparation device comprises a pneumatic quick-change clamping device, a two-shaft linkage workbench, a bone sawing machine, a middle conveying device, a punching machine and a bone grain screening device, wherein the pneumatic quick-change clamping device adapts to clamping of large bones of animals with different shapes and sizes, and the two-axis linkage workbench drives the pneumatic quick-change clamping device to perform two-dimensional translation; the bone sawing machine is used for sawing animal big bones into animal bone slices, and adjusting the thickness of the bone slices; the middle conveying device conveys the animal bone slices to the punching machine for punching, and has a function of screening qualified animal bone slices; the punching machine punches the animal bone slices into bone grains and conveys the bone grains to the bone grain screening device; and the bone grain screening device screens qualified bone grains. According to the sawing-punching integrated preparation device, automatic control integrating two-shaft linkage work, animal big bone sawing, intermediate transportation, multi-die punching and screening collection is achieved, so that the whole logistics process of processing animal big bones into finished bone grains is achieved, and the processing efficiency of the animal big bone grains is greatly improved.

Description

technical field

[0001] The invention relates to the preparation of bone slice materials for orthopedic medicine, in particular to a saw-punching integrated preparation device and method for decellularized bone regeneration repair materials. Background technique

[0002] Acellular bone granules have good osteoinductivity. In some orthopedic operations, acellular bone granules can be efficiently and safely transplanted into the human body as transplant objects. They are effective connectors for the recovery of human bone fragments. However, at present, there is still a lack of high-efficiency and less-loss preparation devices and processing methods for the processing and manufacturing of high-quality acellular bone grains—animal large bones (pig or bovine) bone grains—in China. Therefore, it is imminent to design and research the saw-punching integrated preparation device and method of decellularized bone regeneration repair materials. Contents of the invention
