Description
본 발명은 환자의 배를 개복하지 아니하고 작은 구멍을 내어 복강경 수술을 할 수 있도록 써포트해주는 트로카(TROCAR)에 관한 것으로서, The present invention relates to a trocar that supports laparoscopic surgery by opening a small hole without opening the stomach of the patient,
보다 상세하게는 하나의 트로카에 여러 종류의 수술기구를 장착하여 복강경 시술을 할 수 있도록 하여 환자 복부의 절개 부위를 최소화함과 아울러 적은 수의 트로카를 사용함에 따라 환자의 비용부담을 덜어주고,More specifically, it is possible to minimize the incision site of the patient's abdomen by using various types of surgical instruments in one trocar and to reduce the patient's cost by using a small number of trocars.
트로카에 관통 삽입된 수술기구의 외주연을 실링하여 내부 공기가 유출되는 것을 방지하는 실링부재는 트로카에 착탈이 가능하게 하여, 환자의 상태가 악화되어 복부를 여러 군데 절개하고 다수개의 기존 트로카(즉, 하나의 수술기구만이 관통 삽입되는 트로카)를 사용하여야 하는 상황에서는 실링부재를 본 발명의 트로카에서 분리시켜 기존의 트로카에 장착하여 사용할 수 있도록 한 착탈 가능한 실링부재를 갖는 멀티채널 트로카에 관한 것이다. The sealing member, which seals the outer periphery of the surgical instrument inserted through the trocar and prevents the internal air from leaking out, can be detached and detached from the trocar. In a situation where a car (that is, a trocar into which only one surgical instrument is inserted) is to be used, the sealing member is detachable from the trocar of the present invention and has a detachable sealing member that can be mounted and used on an existing trocar. A multichannel trocar.
복강경 수술은 환자의 복부에 작은 구멍을 뚫고, 이 구멍을 통해 복강의 내부를 관찰하면서 수술하는 방식으로서, 담낭 절제술, 충수돌기 절제술, 결석 제거술, 일반 외과 수술 등에 널리 이용되고 있다. Laparoscopic surgery is a method of drilling a small hole in the abdomen of the patient and observing the inside of the abdominal cavity through the hole, and is widely used for gallbladder resection, appendectomy, stone removal, and general surgery.
종래의 복강경 수술은 복부에 여러 개의 구멍을 뚫고, 각각의 구멍에 트로카를 삽입하고, 각각의 트로카에 내시경, 가스 주입기, 레이저 발생기, 커터 등과 같은 수술기구를 일대일로 관통 삽입시킨 후에 내부를 관찰하면서 수술을 하였다. In conventional laparoscopic surgery, several holes are drilled in the abdomen, a trocar is inserted into each hole, and a surgical instrument such as an endoscope, a gas injector, a laser generator, a cutter, etc. is inserted into each trocar and the inside is observed. The operation was performed.
즉, 종래의 트로카는 하나의 트로카에 하나의 수술기구만이 관통 삽입되는 싱글채널 구조로 되어 있다.That is, the conventional trocar has a single channel structure in which only one surgical instrument is inserted through one trocar.
복강경 수술에는 최소 세 가지의 수술기구가 필요하다. 첫째는 수술시 조직을 잡아주기 위한 복강경 포셉류(forcep)이고, 둘째는 의사가 복강 내부를 관찰하기 위한 내시경이고, 셋째는 환자의 환부를 직접 치료하기 위한 치료기기(예; 레이저 발생기, 초음파 발생기, 커터 등)이다. Laparoscopic surgery requires at least three surgical instruments. The first is a laparoscopic forcep to hold tissue during surgery, the second is an endoscope for the doctor to observe the inside of the abdominal cavity, and the third is a therapeutic device (eg, a laser generator, an ultrasound generator) to directly treat the affected part of the patient. , Cutters, etc.).
