도 2a 내지 도 2c는 본 발명의 일 실시예에 따른 복강경 수술용 투관침을 이용하여 복막을 봉합하는 과정을 보인 예시도이다. Figure 2a to 2c is an exemplary view showing a process of suture the peritoneum using a laparoscopy surgical trocar according to an embodiment of the present invention.
먼저, 도 2a를 참조하면, 시술자는 투관침을 도시된 바와 같이 복막(P)을 관통하도록 삽입한다. 그 후, 복강경 수술을 진행하면서 투관 하우징(10)의 내부 공간을 통해 카메라 또는 수술기구가 복강으로 안내된다. First, referring to FIG. 2A, the operator inserts the trocar through the peritoneum P as shown. Thereafter, the camera or surgical instrument is guided to the abdominal cavity through the internal space of the trocar housing 10 while undergoing laparoscopic surgery.
이상의 복강 내의 시술이 완료되면, 시술자는 복막(P)을 봉합하여야 한다. 이때, 시술자는 봉합사(22)가 연결된 봉합바늘(20)을 일측의 제1 개구부(12a)를 통해 삽입시킨다. 그리고, 제1 개구부(12a)로 삽입된 봉합바늘(20)은 반대측에 위치한 제2 개구부(14a)를 통과하여 복막(P)을 관통한다. 일반적으로 봉합바늘(20)은 봉합사(22)가 선단에 걸어지는 코바늘이 사용된다. 이 상태에서 시술자는 봉합바늘(20)의 선단에 걸어진 봉합사(22)를 분리하고 봉합바늘(20)을 제2 개구부(14a), 제1 개구부(12a)를 통해 배출시킨다. Upon completion of the above intraperitoneal procedure, the operator should suture the peritoneum (P). At this time, the operator inserts the suture needle 20 to which the suture 22 is connected through the first opening 12a on one side. The suture needle 20 inserted into the first opening 12a passes through the peritoneal membrane P through the second opening 14a positioned on the opposite side. In general, the suture needle 20 is a crochet needle that the suture 22 is walked on the tip. In this state, the operator separates the suture 22 hooked to the tip of the suture needle 20 and discharges the suture needle 20 through the second opening 14a and the first opening 12a.
다음으로, 도 2b를 참조하면, 시술자는 제1 개구부(12a)의 반대측에 위치한 타측의 제1 개구부(12b)를 통해 봉합바늘(21)을 삽입시킨다. 그리고, 제1 개구부(12b)로 삽입된 봉합바늘(21)은 반대측에 위치한 제2 개구부(14b)를 통과하여 복막(P)을 관통한다. 이 상태에서 시술자는 봉합바늘(21)의 선단에 다시 봉합사(22)를 걸어준다. 그리고, 시술자는 봉합바늘(21)을 제2 개구부(14b), 제1 개구부(12b)를 통해 배출시킨다.Next, referring to FIG. 2B, the operator inserts the suture needle 21 through the first opening 12b on the other side located opposite the first opening 12a. The suture needle 21 inserted into the first opening 12b passes through the peritoneal membrane P through the second opening 14b positioned on the opposite side. In this state, the practitioner hangs the suture 22 on the tip of the suture needle 21 again. In addition, the operator discharges the suture needle 21 through the second opening 14b and the first opening 12b.
이와 같이 되면, 봉합사(22)가 도 2c에서와 같이 대각 방향으로 서로 엇갈리게 되고, 시술자는 투관 하우징(10)을 제거하고 봉합사(22)의 매듭을 지으면 복막(P)의 봉합이 완료된다. In this case, the sutures 22 are staggered with each other in a diagonal direction as shown in FIG. 2C, and the operator removes the bushing housing 10 and knots the sutures 22 to complete the suture of the peritoneum P. FIG.
이상에서 살펴본 바와 같이, 본 발명에 의한 투관침에 의하면 투관 하우징(10)을 제거하지 않은 상태에서 시술자가 복막(P)의 봉합을 쉽게 할 수 있으며, 수술 시간도 단축될 수 있다.As described above, according to the trocar needle according to the present invention, the operator can easily suture the peritoneum (P) in a state where the trocar housing 10 is not removed, and the operation time can be shortened.
본 발명의 권리범위는 위에서 설명된 실시예에 한정되지 않고 청구범위에 기재된 바에 의해 정의되며, 본 발명의 기술분야에서 통상의 지식을 가진 자가 청구범위에 기재된 권리범위 내에서 다양한 변형과 개작을 할 수 있다는 것은 자명하다.The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims.
