In minimally invasive surgeries, it can be difficult to reach desired anatomic areas with rigid instruments, especially when obstacles are present in the surgical corridor (e.g., during transnasal pituitary surgery). We developed a new kind of suction device constructed of the shape-memory alloy Nitinol (nickel titanium), which is adaptable to a patient's specific anatomy. Use of this device minimizes surgical risks by allowing physicians to use an endonasal transsphenoid approach. The suction device, which is equipped with a cannula made of the shape-memory alloy, was planned and manufactured with three different handpiece designs. Experienced pituitary surgeons tested the prototypes in human cadaver skulls and rated the devices on specific questionnaires. The results of their evaluation indicate that this device is a suitable tool for improving the surgical procedure. Its potential benefits include a more effective surgery and reductions in the risk of injury, the duration of surgery, and costs.
在微创手术中，使用刚性器械可能难以到达理想的解剖区域，尤其是当手术通道存在障碍物时（例如在经鼻垂体手术中）。我们开发了一种由形状记忆合金镍钛诺（镍钛）制成的新型吸引装置，它能够适应患者的特定解剖结构。通过允许医生采用鼻内镜经蝶窦入路，使用该装置可将手术风险降至最低。这种吸引装置配备了由形状记忆合金制成的套管，其设计了三种不同的手持件。经验丰富的垂体外科医生在人类尸体头骨上测试了这些原型，并通过特定问卷对这些装置进行了评分。他们的评估结果表明，该装置是改进手术过程的合适工具。其潜在益处包括手术更有效，以及降低受伤风险、手术时长和成本。
