简要总结
In this research, a new bone harvesting technique is introduced in order to find an iliac crest bone harvesting method for patients with less trauma, less postoperative pain in donor sites, and lower incidence of postoperative complications, so as to get ideal bone grafting materials at a small cost, enhance the effect of osteogenesis repair on bone defect or fusion site, and improve the operation quality.
详细描述
Based on the domestic and foreign research on minimally invasive bone harvesting, we have developed a disposable battery-powered bone harvesting device that can be used for milling bone tissues. Using this disposable battery-powered bone harvesting device, cancellous bone milling can be performed in a small bone hole with a diameter of 7.5 mm. The morselized bone or bone chips it milled can be used for bone fusion at the desired site. The technique adopts patented milling tool bit and electric drive, with high operation efficiency, so the surgery can be completed very quickly. The bone trauma in the operation can be significantly reduced and the pain in the donor site can be greatly alleviating. Moreover, the technique can obviously reduce the duration of bone harvesting and the cost of operating room. In addition, significant reductions in postoperative pain will also be helpful to a range of clinical advantages and benefits, such as the average hospitalization days, and will be expected to benefit significantly in patients undergoing autologous bone harvesting.
