In patients after laryngectomy it is sometimes difficult to form an esophagotracheal shunt for secondary implantation of an artificial larynx. We have developed a special trocar for this purpose. This new instrument allows the surgeon to form an esophagotracheal shunt in varying anatomic pharynx funnels. A special modified point helps avoid granulation and stenoses surrounding the fistula.
对于喉切除术后的患者，有时难以形成用于人工喉二期植入的食管气管分流通道。我们为此研发了一种特殊的套管针。这种新器械能让外科医生在不同解剖结构的咽漏斗中形成食管气管分流通道。一种特殊的改良尖端有助于避免瘘口周围出现肉芽组织和狭窄。
