Description

투관침 개방창 봉합 장치Trocar opening window closure device

본 발명은 복강경 수술 기술에 관한 것으로서, 더욱 상세하게는 복강경 수술 과정에서 투관침(trocar)에 의해 발생한 개방창을 봉합하는 장치에 관한 것이다.The present invention relates to a laparoscopy technique, and more particularly, to a device for suturing an open window generated by a trocar during a laparoscopy procedure.

복강경 수술은 기존의 개복 수술과는 달리 복부를 0.5cm 내지 1cm로 절개하여 다수의 구멍을 뚫고 복강경을 삽입하여 복강 내부를 관찰하면서 수술한다. 투관침(trocar)은 복강경 수술 시 피부와 복막을 관통하여 설치되어서 복강경 및 수술기구를 복강 내로 안내한다. 복강경 수술 시 피부와 복막에는 투관침에 의한 개방창이 발생하게 된다. 투관침에 의한 개방창은 봉합사에 의해 봉합되는데, 복막과 피부층 사이의 지방층이 두꺼운 비만 환자의 경우 복막을 봉합하기 어렵다. 그에 따라, 투관침 개방창을 용이하게 봉합하기 위한 기술이 요구되고 있다.Laparoscopic surgery, unlike the conventional open surgery, incision to the abdomen 0.5cm to 1cm through a plurality of holes and laparoscopic insertion to observe the inside of the abdominal cavity. Trocar is installed through the skin and peritoneum during laparoscopic surgery to guide the laparoscopic and surgical instruments into the laparoscopic. During laparoscopic surgery, open windows caused by trocars occur on the skin and peritoneum. The open window by the trocar is sutured by suture, which is difficult for the obese patient with a thick fat layer between the peritoneum and the skin layer. Accordingly, there is a need for a technique for easily closing the trocar opening window.
