Description

담석파괴 장치기용 엘록트로드{Electrode for gallstone destruction machine}Electrode for gallstone destruction machine}

본 발명은 의료기기의 한 종류로서 레이저 빛 발산을 이용하여 체내의 담석을 파괴 제거하는 장치기에 적용 사용하는 엘록트로드의 개량에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an improvement in the ellok rod used in a device for destroying and removing gallstones in the body by using laser light divergence as a type of medical device.

일반적으로 체내에서 생성된 담석을 파괴하는 의료기기로서 담석 파괴장치기가 널리 사용하고 있으며, 상기 담석파괴장치기에는 엘록트로드를 설치하여 엘록트로드에 구성된 전극의 스파크로부터 발생되는 레이저파를 이용, 체내의 담석을 파괴, 제거하고 있다.In general, as a medical device for destroying gallstones generated in the body, a gallstone destruction device is widely used. The gallstone destruction device is equipped with an elut rod to use laser waves generated from sparks of electrodes formed on the elut rod. It is destroying and removing gallstones in the body.

그러나 상기 담석파괴 장치기에 부착되어 레이저 빛 발산을 유도하는 엘록트로드는 전극의 스파크에 의한 레이저 빛 발산시 심한 충격이 발생하게 되고, 따라서 스파크충격에 의해 전극을 지지고정하고 있는 엘록트로드의 본체가 쉽게 파손되는 것이었다.However, the Elochrod, which is attached to the gallstone breaker and induces laser light divergence, causes severe impact when laser light is emitted by the spark of the electrode, and thus the main body of the Elkrod which fixes and supports the electrode by the spark impact. It was easily broken.

이는 종래사용되고 있는 엘록트로드의 재질자체가 나일론6의 단일물성으로 구성되어 있기 때문이다.This is because the material of the used rod itself is composed of a single material of nylon 6.

즉 나일론6의 경우 재질특성상 강성은 있으나 유연성이 미흡하기 때문에 레이저 빛 발산을 위한 전극의 스파크 충격시 충격을 흡수하는 성질이 약하여 전극을 지지하고 있는 본체가 쉽게 파손되는 등의 문제점이 있는 것이었다.In other words, in case of nylon 6, the rigidity of the material characteristics is insufficient, but the flexibility is insufficient, so that the shock absorbing property during the spark impact of the electrode for laser light emission is weak, and thus the main body supporting the electrode is easily damaged.

본 발명은 이러한 종래의 제반 문제점을 시정하고자 의료용 담석 파괴장치기에 사용되는 엘록트로드를 구성함에 있어서, 전극을 지지하는 본체의 재질을 충격에 잘 견디면서 충격을 흡수할 수 있는 재질로 구성하여 사용중 레이저 빛 발산을 위한 전극의 스파크시 발생하는 충격에도 파손되지 않고 견딜수 있도록 하여 내구성이 우수한 제품을 제공받을 수 있도록 한 것이다.The present invention in the construction of the ellipte rod to be used in the medical gallstone destruction device to correct the various problems of the prior art, the material of the body supporting the electrode is made of a material that can absorb the shock while absorbing the shock well in use It is to be able to withstand the impact generated when sparking the electrode for laser light emission without being damaged to provide a durable product.

상기 목적을 달성하기 위하여 본 발명은 강성이 우수한 나일론6과 진동흡수성과 유연성이 우수한 유연나일론을 적절한 비율로 혼합하여 엘록트로드의 전극을 지지고정하는 본체를 구성케 한 것이다.In order to achieve the above object, the present invention mixes nylon 6 having excellent stiffness with flexible nylon having excellent vibration absorption and flexibility at an appropriate ratio to configure a main body supporting and fixing the electrode of the elut rod.

상기에서 나일론6과 유연나일론의 혼합비율은 62∼72% : 25∼35%의 비율이 적합하고, 여기에 약3%의 이형재가 첨가된다.The mixing ratio of nylon 6 and flexible nylon is preferably 62 to 72%: 25 to 35%, and about 3% of the release material is added thereto.

본 발명에서 사용되는 재질은 반드시 담석파괴장치기에 사용하는 엘록트로드에만 적용 사용가능한 것은 아니고, 일반산업분야에서 강성과 연성을 동시에 요구하는 부품의 재질로도 사용가능할 것으로 판단된다.The material used in the present invention is not necessarily applicable only to the rod of the rock used in the gallstone breaker, and it is determined that the material may be used as a material of a component that simultaneously requires rigidity and ductility.

이하 본 발명의 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명에서 제공하고자 하는 엘록트로드(2)의 개략적인 구성도로서, 본체(4)의 내측단부에 레이저 빛 발산을 유도하기 위한 전극(6)을 일체로 구성되게 하되, 상기 본체(4)는 다음과 같은 재질로 구성되어 있다.FIG. 1 is a schematic configuration diagram of an erotic rod 2 to be provided in the present invention, wherein an electrode 6 for inducing laser light divergence is integrally formed at an inner end of the main body 4, but the main body (4) consists of the following materials.

즉 나일론6과 유연나일론을 적절한 비율로 혼합 성형한 것이다.In other words, nylon 6 and flexible nylon are mixed and molded at an appropriate ratio.

상기에서 나일론6과 유연나일론의 혼합비율은 나일론6, 63∼73%에 유연나일론 25∼35%, 여기에 원활한 제품성형을 위한 이형재 2∼3%를 첨가한 혼합물로 본체(4)를 성형하여서 된 것이다.In the above, the mixing ratio of nylon 6 and flexible nylon is formed by mixing the body 6 with a mixture of nylon 6, 63 to 73%, flexible nylon 25 to 35%, and release material 2 to 3% for smooth product molding. It is.

이와 같이 구성된 본 발명의 엘록트로드(2)는 의료용 담석파괴장치기에 설치하여 엘록드로드의 본체(4)에 구성된 전극(6)의 스파크에 의해 충격과 함께 레이저 빛이 발산하고, 상기 레이저 빛을 이용하여 체내에 있는 담석을 파괴 제거한다는 것은 종래와 같다.In the structure of the present invention, the rock rod 2 is installed in a medical gallstone breaker and the laser light is emitted along with the impact by the spark of the electrode 6 formed on the main body 4 of the rock lock, and the laser light Destruction and removal of gallstones in the body using the same as conventional.

그러나 본 발명에서는 레이저 빛 발산을 위한 전극(6)의 스파크 현상시 심한 충격이 발생하게 되나, 전극(6)을 지지하고 있는 본체(4)가 강성이 우수한 나일론6과 유연성과 내충격성이 우수한 유연나일론을 적절한 비율로 혼합 사용한 재질로 구성되어 있어 충격 및 진동을 흡수 완화하게 되므로 장기간 사용하게 되더라도 전극의 스파크 충격에 의한 엘록트로드(2)의 파손현상을 방지할 수 있게 된다.However, in the present invention, a severe impact occurs when sparking the electrode 6 for laser light emission, the body 4 supporting the electrode 6 is a nylon 6 excellent in rigidity and flexible and excellent in impact resistance It is composed of a material using a mixture of nylon in an appropriate ratio to absorb and mitigate shock and vibration, so that even if used for a long time it can prevent the damage of the elecrod rod (2) by the spark impact of the electrode.

상기에서 소량의 이형재는 제품의 성형공정에서 원활한 탈형을 위한 것이다.Small amount of release material in the above is for smooth demolding in the molding process of the product.

또한 나일론과 유연나일론을 약7:3의 비율로 혼합하는 것이 가장 이상적이며, 상기에서 나일론6이나 유연나일론의 투입비율이 변하게 되면 본 발명에서 제공받고자하는 이상적인 성질의 재질을 얻기 곤란하다.In addition, it is most ideal to mix nylon and flexible nylon at a ratio of about 7: 3, and when the input ratio of nylon 6 or flexible nylon is changed, it is difficult to obtain an ideal material to be provided by the present invention.

본 발명에서 제공되는 재질은 반드시 엘록트로드에만 적용 사용가능한 것이 아니라, 일반 산업분야에서 강성과 유연성을 동시에 필요로 하는 제품에 적용사용할 수도 있다.The material provided in the present invention is not necessarily applicable only to the rod of the electrode, but may be applied to a product which simultaneously requires rigidity and flexibility in the general industrial field.

따라서 본 발명은 의료용으로 사용되고 있는 담석파괴장치기의 엘록트로드를 구성함에 있어서 전극을 지지 고정하는 본체를 나일론6과 유연나일론을 적절히 혼합하여 압출 성형토록 하므로서 내충격성이 우수한 엘록트로드를 제공받을 수 있게 되는 것이다.Therefore, in the present invention, the main body for supporting the electrode in the construction of the rock rod of the gallstone breaker device used for medical purposes can be provided with an impact rod having excellent impact resistance by properly mixing and extruding nylon 6 and flexible nylon. Will be.
