Measuring the remnant bone thickness during surgical drilling

脊柱外科手术的原因有很多，包括脊柱侧凸矫正或脊柱创伤 在一次事故之后。青少年特发性脊柱侧凸在女孩中更常见，患病率最高为1.2% 12岁的时候在大多数脊柱手术中，椎骨被钻孔以插入固定假体所需的锚定件， 植入物到位。在椎骨钻孔期间，外科医生在钻穿骨时必须小心， 这可能导致脊髓的永久性损伤。然而，浅钻可能导致不稳定的 主播脊柱侧凸手术并发症发生率高，辅助外科医生进行创新医疗 设备可以帮助降低该速率。在这项拨款申请中调查的概念是使外科丝锥适应于 包括在尖端处的超声转换。超声换能器的目的是定位目标，例如 沿着敲击轴沿着脊髓。成功开发所提出的概念，然后可以应用于 其他手术工具，以提高患者的安全性。

Spine surgeries may be performed for a number of reasons including scoliosis correction or spine traumas following an accident. Adolescent idiopathic scoliosis is more common in girls with a peak prevalence of 1.2% at age 12. In most spine surgeries, the vertebrae are drilled to insert anchors required to hold prosthesis or implants in place. During vertebrae drilling, the surgeons must be careful while drilling through the bone as this may lead to permanent damage to the spinal cord. However, shallow drillings may lead to unstable anchors. Scoliosis surgery has a high rate of complications and assisting surgeons with innovative medical devices may help reduce this rate. The concept investigated in this grant application is to adapt a surgical tap to include ultrasonic transduction at the tip. The aim of the ultrasonic transduction is to locate targets such as the spinal cord along the tapping axis. Successful development of the proposed concept could then be applied to other surgical tools to improve patient safety.
