Abstract

The invention provides a novel multifunctional bone crusher device for bone grafting for spine surgery, and relates to the technical field of medical apparatuses and instruments, the novel multifunctional bone crusher device comprises a bone crushing main body; the bone crushing upper cover is connected to the top of the bone crushing main body through a hinge; the driving part is fixedly connected to the rear end surface of the bone crushing main body; the number of the feeding sliding seats is two, and the two feeding sliding seats are slidably connected to the left side and the right side of the interior of the bone crushing body correspondingly; and the two sets of bone crushing pieces are arranged, and the two sets of bone crushing pieces are rotationally connected to the inner sides of the two sets of feeding sliding seats correspondingly. The bone crushing efficiency is greatly improved, the problem of low processing efficiency caused by sliding or rotating of donor bones is effectively avoided, the production efficiency is high, the granularity of the processed crushed bones is uniform, and the problems that the existing bone crushing device generally adopts a crushing mode to carry out bone crushing processing, the bone particles are not uniform after bone crushing, and the processing efficiency is low are solved. Meanwhile, the donor bone is easy to roll or slide in the bone crushing process, so that the bone crushing efficiency is influenced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a novel multifunctional bone crusher device for bone grafting used in spinal surgery. Background technique [0002] Bone grafting is a treatment method in which healthy bone tissue is obtained from other parts of the body and transplanted into the nonunion or bone defect. In lateral spine surgery, spinal fusion is often used to achieve spinal repair. and treatment, the donor bone needs to be crushed into granules before bone grafting. [0003] However, the current bone crushing device generally adopts the crushing method for bone crushing. After the bone crushing, the bone particles are not uniform, and the donor bone tends to roll or slide during the bone crushing process, which affects the bone crushing efficiency. SUMMARY OF THE INVENTION [0004] In view of this, the present invention provides a novel multifunctional bone crusher device for bone grafting in spi...
