内窥镜已成为经蝶垂体手术的重要工具，因为它具有全景视野和能够看到视线以外的结构。然而，用于这些手术的常规专用器械有时无法到达角度内窥镜所显示的区域，并且器械的可操作性受到限制。为了克服或减少这些问题，我们构建了一种新的柔性肿瘤钳，它可以通过鼻内或唇下路径放置在手术区域后操纵改变形状，以达到任何理想的肿瘤解剖和切除位置。我们将该仪器应用于鼻内窥镜下垂体肿瘤切除术，并辅以显微外科手术治疗20例。灵活的镊子能够进入经蝶窦垂体手术的常规专用器械无法轻易到达的部位，尽管内窥镜显示。在本系列中没有观察到并发症，证实了新设计的柔性钳的安全性。我们新开发的柔性钳提高了经蝶窦内镜切除垂体肿瘤的器械机动性，特别是那些位于海绵窦外侧或额部延伸的肿瘤。该仪器的使用使内窥镜全景可视化在肿瘤切除中发挥了最大的作用。
The endoscope has become an essential tool for transsphenoidal pituitary surgeries because of the panoramic view and the ability to visualize structures beyond the direct line of vision. However, the regular dedicated instruments for these surgeries sometimes do not reach the areas visualized by an angled endoscope, and instrument maneuverability is limited. To overcome or minimize these problems, we constructed a new flexible tumor forceps that can be manipulated to change shape after placing into the surgical fields via the endonasal or sublabial route, to reach any desirable location for tumor dissection and excision. We applied this newly developed instrument in endonasal endoscopic resection complementing microsurgical procedure in 20 cases of pituitary tumors. The flexible forceps was able to access sites where regular dedicated instruments for transsphenoidal pituitary surgeries could not readily reach despite endoscopic visualization. No complication was observed in the present series, confirming the safety of the newly designed flexible forceps. Our newly developed flexible forceps improves the instrument maneuverability of endoscopic transsphenoidal resection of pituitary tumors, especially those located laterally at the cavernous sinuses or with frontal extension. The use of this instrument makes the best use of endoscopic panoramic visualization for tumor removal.
