Description

혈관 전용 가위Vascular scissors
본 발명은 혈관 전용 가위에 관한 것으로, 더욱 상세하게는 혈관과 같은 미세한 조직을 요구되는 절개 길이만큼 정밀하고 편리하게 절개시킬 수 있도록, 구조가 개선된 혈관 전용 가위에 관한 것이다. TECHNICAL FIELD The present invention relates to vascular scissors, and more particularly, to vascular scissors, in which the structure is improved to precisely and conveniently cut fine tissue such as blood vessels by the required incision length.
정밀한 혈관절개를 위해서는 도 1에 도시된 Potts-Smith scissors(100; Potts scissors라 불리우기도 함)와 같은 혈관 전용 가위가 사용된다. 이러한 Potts scissors(100)는, 도 2와 같이 수술시에 혈관(A)에 절개를 가하거나 혈관(A)을 다듬기 위해서 개발된 것으로, 사용시 다른 가위의 사용에 비하여 매우 정밀한 기술과 과정이 요구되고, 이러한 요구에 따른 정밀한 시술을 위해 혈관의 위치나 각도에 따라서 다양한 사이즈, 각도, 사용법의 Potts scissors가 개발되어 상용되고 있다.For precise vascular incision, vascular scissors such as Potts-Smith scissors (also referred to as 100 (also called Potts scissors)) shown in FIG. 1 are used. This Potts scissors (100), as shown in Figure 2 was developed to incision in the blood vessels (A) at the time of surgery or to cut the blood vessels (A), when using a very precise technology and process is required compared to the use of other scissors Potts scissors of various sizes, angles, and usages have been developed and commercialized according to the location and angle of blood vessels for precise procedures according to these requirements.
비교적 큰 혈관의 절개나 비교적 술자와 가까이 위치한 혈관의 절개는 술자가 눈으로 직접 확인해 가면서 정확한 절개가 용이하다.Incision of relatively large vessels or incisions of vessels located relatively close to the operator is easy to make an accurate incision as the operator directly checks with the eye.
반면, 예를 들어서 관상동맥우회술을 시행하면서 관상동맥을 절개하는 경우에는, 관상동맥의 직경이 매우 가늘고(0.5~2mm), 그 혈관이 술자가 수술하기 어려운 몸 속 깊숙히 위치하는 경우가 많기 때문에, 술자가 직접 눈으로 절개의 정도나 상태를 정확히 확인하면서 절개하는 것이 어렵다.On the other hand, for example, in the case of coronary artery incision during coronary artery bypass surgery, the diameter of the coronary artery is very thin (0.5-2 mm), and the blood vessels are often located deep in the body, which is difficult for the operator to operate. It is difficult for the surgeon to make an incision while accurately checking the degree or condition of the incision.
이 경우 임상에서는 대부분 정밀한 칼로 혈관에 약간의 구멍을 낸 다음, Potts scissors의 아랫쪽 날을 혈관 구멍으로 삽입하여 혈관의 주행이나 각도를 확인한 다음, 술자의 손가락 끝의 감각과 경험을 바탕으로 "한 번의 가위질"을 적절히 시행하여 혈관을 절개하게 된다.In this case, most of the time, the clinician makes a small hole in the vessel with a precise knife, and then inserts the lower blade of the Potts scissors into the vessel hole to check the driving or angle of the vessel. "Scissoring" is done properly to dissect blood vessels.
한 번의 가위질로 매우 가는 혈관의 절개가 완료되기 때문에 도 3과 같이 손가락 구멍이 없는 특수하게 제작된 Potts scissors(200)를 사용한다. 이러한 Potts scissors(200)는, 연필 쥐듯이 안정적으로 가위를 파지할 수 있기 때문에 더욱더 정밀한 시술이 가능하고, 한 번의 가위질 후 손가락의 힘 조절과 함께 내부의 스프링 장치 작동으로 자동으로 열리기 때문에 그 사용이 편리하다. Since the incision of the very thin blood vessel is completed by one scissor, a specially manufactured Potts scissors (200) without a finger hole is used as shown in FIG. 3. Since the Potts scissors (200) can hold the scissors stably like a pencil, it is possible to perform a more precise procedure. It is convenient.
그러나, 이러한 Potts scissors(200)를 사용함에도 불구하고 술자가 가위를 오므리는 정도와 실제로 혈관이 절개되는 정도를 일치시키기가 어렵기 때문에, 결국 가위질에 의한 절개 길이는 술자의 손가락 끝 감각과 경험에 의존할 수 밖에 없다.However, despite the use of the Potts scissors (200), it is difficult to match the degree of the surgeon's pruning of the scissors with the actual incision of the blood vessels. There is no choice but to depend.
따라서, 혈관의 절개가 계획된 절개길이보다 길어지거나 짧아지는 경우가 종종 발생하게 되는데, 직경이 매우 작은 혈관을 수술하는 경우 이러한 미세한 절개길이의 차이는 수술의 진행을 어렵게 하고 좋지 못한 결과를 초래한다.Therefore, the incision of blood vessels is often longer or shorter than the planned incision length, and when the vessel is operated with a very small diameter, such a small difference in incision length makes the procedure difficult and leads to poor results.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 시술자가 절개된 길이를 실시간으로 파악할 수 있게 하고, 혈관과 같은 미세한 조직을 요구되는 길이만큼 정확하고 편리하게 절개시킬 수 있게 하는 혈관 전용 가위를 제공하고자 하는 것이다. The present invention has been made to solve the above problems, an object of the present invention is to enable the operator to determine the incision length in real time, and to precisely and conveniently incise fine tissues such as blood vessels as required length To provide a vessel-specific scissors to make.
