Most spinal surgery requires bone fusion. Bone grafts or bone substitutes are often used to achieve bone fusion during the spinal fusion surgery. Compared with allograft, bone xenograft and artificial bone substitutes, patient-derived autogenous bone granules are the best choice. The researchers designed an autologous bone preparation system that consisted of an autologous bone pulverizer and an autologous bone collection system. The bone fragments can be quickly broken to the appropriate granularity in a sterile sealed device after the bone mass is obtained. The bone fragments collection system can be connected to the surgical aspirator to collect the bone fragments cut by grinding drill for bone grafting.
