Description

전기수술용 메스{A knife for electric operation}A knife for electric operation

본 발명은 의료 수술중 피부를 절개할 때에 절개되는 조직과 절개용 메스와 접착되는 것을 막기 위하여 비접착 물질의 코팅으로 이루어진 전기수술기용 메스에 관한 것이다.The present invention relates to an electrosurgical scalpel made of a coating of a non-adhesive material to prevent adhesion to the incisional tissue and the incision scalpel when the skin is incision during medical surgery.

주지하는 바와 같이 외과에서 수술을 할 때에 즉, 피부를 절개할 때에 메스를 사용하게 된다.As is well known, a scalpel is used during surgery in surgery, i.e., incision of the skin.

이때에 외과의사는 메스로 피부 조직을 절개함과 함께 절개로 인한 지혈을 함께 하는 어려움이 있어 왔으나 새롭게 개선된 전기 수술기용 메스는 고주파 에너지에 의해 메스를 고열로 가열시켜 고열에 의해 절개피부의 혈관을 막아 출혈을 방지하는 외과용 메스가 개발되면서 많은 외과의사들에게 필수적인 메스로 사용되고 있는 실정이다.At this time, the surgeon has had difficulty in cutting the skin tissue with a scalpel and coagulation hemostasis due to the incision, but the newly improved scalpel for electrosurgical operation heats the scalpel to high heat by high-frequency energy to open blood vessels of the incision skin by high heat. The development of a surgical scalpel to prevent bleeding by preventing the situation is being used as an essential scalpel for many surgeons.

이러한 메스는 고주파 에너지를 메스에 전달시켜 메스에서 적합한 열을 발생시키고 이 열에 의해 절단되는 혈관을 막음으로서 출혈을 최소화시키도록 한 것이며 이러한 출혈의 방지로 외과의사가 수술을 보다 정밀하고 안전하게 실시할 수 있도록 하고 있다..These scalpels deliver high-frequency energy to the scalpel to generate the appropriate heat in the scalpel and minimize the bleeding by blocking the blood vessels cut by the scalpel, which prevents the surgeon from performing the surgery more precisely and safely. I'm trying to ..

즉, 수술용 메스(mes/ knife)는 외과수술에 사용하는 작고 예리한 절단 칼과 함께 최근에는 절개와 동시에 지혈시키는 전기메스가 알려지고 있다. 이 전기메스는 고주파(高周波) 작용을 이용하여 조직에 압력을 가함이 없이 조직을 예리하게 절단할 수 있는 데다가 세소혈관(細小血管)이나 모세관을 폐쇄함으로써 출혈 없이 수술할 수 있는 특징이 알려지면서 최근의 수술에서는 이러한 전기메스를 이용하고 있다.In other words, a surgical scalpel (mes / knife) with a small and sharp cutting knife used for surgical operation in recent years, an electric scalpel for hemostasis at the same time as the incision is known. The electric scalpel is known to be able to cut the tissue sharply without applying pressure to the tissue by using high frequency waves and to operate without bleeding by closing the small blood vessel or the capillary tube. 'S surgery uses this electric scalpel.

이러한 전기메스는 수술하는 동안 지혈을 하는데 유용한 것으로 판명되었으나, 문제점으로는 피부조직이 메스에 달라붙고 이로 인해 효과적인 절개를 할 수 없는 단점이 발생되고 있다.The electric scalpel has been found to be useful for hemostasis during surgery, but the problem is that the skin tissue is stuck to the scalpel and thus there is a disadvantage that an effective incision cannot be made.

이에 따라 상기 문제점을 개선하기 위하여 메스 표면에 전도성이 좋거나 최소한 메스와 조직이 전류가 통하는 비접착 물질을 코팅시켜 피부 조직이 덜 부착되고 또는 덜 타도록 한바 있다.Accordingly, in order to improve the above problem, the surface of the scalpel has a good conductivity or at least the scalpel and the tissue are coated with a non-adhesive material through which current flows so that the skin tissue is less attached or burned less.

이러한 비접착성을 위한 전기수술기용 메스와의 관련 특허는 미국 특허 제4,314,559호, 제4,333,467호, 제4,161,950호, 제4,481,057호, 제4,785,807호 등이 알려지고 있다.Related patents related to such non-adhesive scalpels are known from US Pat. Nos. 4,314,559, 4,333,467, 4,161,950, 4,481,057, 4,785,807, and the like.

상기 미국특허 제4,785,807호에서의 방법은 전기수술기용 칼에 비접착 물질을 코팅함에 따라 수술시 발생하는 문제점을 해소하였으며, 또한 전도성을 높이도록 코팅되어 금속성 칼에 전류가 골고루 퍼지는 효과를 발휘하고 있다.The method in US Pat. No. 4,785,807 solves the problem caused by the operation by coating the non-adhesive material on the electrosurgical knife, and is also coated to increase the conductivity, thereby exerting the effect of spreading the current evenly on the metallic knife. .

이러한 비접착성 물질을 코팅하는 선발명은 스테인레스의 전기수술기용 메스를 부식과 벗겨지는 것을 방지하기 위해 프라이머 코팅을 하고 2차로 프라이머 코팅을 보호하기 위해 불소탄화수소를 코팅을 함으로서 그 두께가 0.0076mm에 달하여 두께가 두껍게 구성된다.The invention of coating the non-adhesive material has a primer coating to prevent corrosion and peeling off of the stainless steel electrosurgical scalpel and a fluorohydrocarbon coating to protect the primer coating on its second layer, reaching a thickness of 0.0076 mm. It is made thick.

즉, 상기 코팅부는 두께가 두꺼우면 전기에너지가 코팅 두께 때문에 수술하고자 하는 조직에 전기에너지의 도달을 저해시켜 열을 적절히 전달시키지 못함으로 출혈방지의 효과를 저하시키는 문제점을 가지고 있는 것이다.That is, if the coating is thick, the electrical energy has a problem of lowering the effect of preventing bleeding by preventing heat from reaching the electrical energy to the tissue to be operated due to the thickness of the coating and not properly transferring heat.

또한 상기 발명들은 스테인레스 메스를 센딩(Sanding)하여 VM7799(미국 듀폰사(Dupont)제조의 상품명)가 혼합한 듀폰사의 테프론(Teflon) 850-300(미국 듀폰사(Dupont)제조의 상품명)에 침전 코팅과 함께 섭씨 232℃에서 5에서 10분 정도 건조시키는 공정과,In addition, the above inventions are coated by depositing stainless steel scalpel on Dupont's Teflon 850-300 (trade name manufactured by Dupont, USA) mixed with VM7799 (trade name manufactured by Dupont, USA). And drying for 5 to 10 minutes at 232 ℃,

상기 건조된 공정의 1차코팅된 부재를 다시 듀폰사의 테프론(Teflon) 455-119(불소 탄화수소)를 0.0051mm두께로 뿌려 코팅하고 이를 섭씨 398℃에서 42분 정도 건조하게 되는 것이다.The first coated member of the dried process is coated with Dupont's Teflon 455-119 (fluorinated hydrocarbon) to a thickness of 0.0051mm and dried for 42 minutes at 398 ° C.

이에 따라 상기 1~2차의 코팅은 약 0.0076mm 두께로 코팅되게 되나, 이와 같이 코팅두께가 이루어지면 전기에너지가 혈관에 도달되는 것을 저해시켜 열을 적절히 전달시키지 못함으로 출혈방지의 효과를 저하시키는 문제점이 발생되고 또는 2차코팅의 두께가 얇으면 고주파 에너지가 수술하고자 하는 조직을 과다하게 작용하여 상처를 입힐 수 있는 문제점을 야기하게 되는 문제와 함께 건조온도를 1차에서 섭씨 232℃와 2차에서 398℃에서 건조코팅함으로서 고온에서 쉽게 코팅층이 연소되는 문제가 발생되고 있다.Accordingly, the first and second coatings are coated with a thickness of about 0.0076 mm, but when the coating thickness is made, the electrical energy is prevented from reaching the blood vessels, thereby failing to properly transfer heat, thereby reducing the effect of preventing bleeding. If a problem occurs or the thickness of the secondary coating is too thin, the high-frequency energy causes excessive problems on the tissue to be operated, causing a problem that can cause injury. Dry coating at 398 ℃ in the problem that the coating layer is easily burned at a high temperature is occurring.

또한 상기에서 이용된 듀폰사의 테프론 850-300(미국 듀폰사(Dupont)제조의 상품명)은 생산을 중단함에 따라 상기 선 발명을 실시할 수 없는 문제점을 가지고 있는 것이다.In addition, DuPont's Teflon 850-300 (trade name of Dupont, USA) is used as described above, and the above-mentioned invention cannot be carried out as the production is stopped.

본 발명은 상술한 종래의 문제점을 감안하여 이를 개선하기 위하여 안출된 것으로서 특히, 듀폰사의 테프론 455-119(미국 듀폰사(Dupont)의 제조 상품명)을 사용하지 않고 850-214P PTFE소재를 이용하여 제조함으로 코팅층의 부착력과 함께 고온에서 연소되는 않는 사용효과를 발휘하여 수술작업이 용이하고 코팅층이 보다 얇은 두께로 코팅되어 사용효과를 증대시켜 종래의 문제점을 개선한 발명에 관한 것이다.The present invention has been made in view of the above-described conventional problems, and in particular, manufactured using 850-214P PTFE material without using DuPont's Teflon 455-119 (trade name of Dupont, USA). By using the adhesion of the coating layer exhibits a use effect that does not burn at a high temperature, the operation is easy and the coating layer is coated with a thinner thickness to increase the use effect to improve the conventional problems.
