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.

脊柱手术可以出于多种原因进行，包括脊柱侧弯矫正或脊柱创伤 事故发生。青少年特发性脊柱侧弯在峰值患病率为1.2％的女孩中更为常见 在12岁时。在大多数脊柱手术中，都会钻椎骨以插入持有假体或 植入物。在椎骨钻孔期间，外科医生在钻孔时必须小心 这可能会导致对脊髓的永久损害。但是，浅钻可能导致不稳定 锚。脊柱侧弯手术的并发症发生率很高，并为外科医生提供了创新的医疗 设备可能有助于降低此速度。该赠款申请中研究的概念是调整手术点击 在尖端包括超声转导。超声转导的目的是定位诸如 沿着敲击轴的脊髓。然后可以将提出概念的成功发展应用于 改善患者安全的其他手术工具。
