Description

내시경용 카테터 조립체Endoscope Catheter Assembly

본 발명은 내시경용 카테터 조립체에 관한 것으로, 더욱 상세하게는 렌즈와 광섬유를 가이드하는 카테터를 이용하여 환자의 체내 환부를 진단하고 치료할 수 있는 구조를 가진 내시경용 카테터 조립체에 관한 것이다.The present invention relates to an endoscope catheter assembly, and more particularly, to an endoscope catheter assembly having a structure capable of diagnosing and treating a patient's body affected by using a catheter for guiding the lens and the optical fiber.

카테터는 환자의 진단 또는 치료의 목적으로 체내에 삽입되는 의료용 기구이다. 카테터는 길고 가느다란 관 형태로 제작된다. 카테터 관을 통해서 치료 기구를 삽입하여 환부를 고주파 치료하기도 하고 약물을 주입하여 치료 하기도 하며 조직을 절개하여 검사하기도 한다.A catheter is a medical device inserted into the body for the purpose of diagnosing or treating a patient. The catheter is made in the form of a long thin tube. The treatment device is inserted through a catheter tube to treat the affected area by high frequency treatment, by injecting drugs, or by dissecting the tissue.

카테터는 구조에 따라 심혈관, 비뇨기과, 위장, 신경 혈관, 안과 등 다양한 분야에 사용된다.Catheter is used in various fields such as cardiovascular, urological, gastrointestinal, neurovascular, ophthalmic, depending on the structure.

기존에 척추 시술용으로 사용되는 내시경도 이와 같은 카테터의 구조를 가진다. 종래의 척추용 내시경은 렌즈와 광섬유 채널뿐만 아니라 워킹 채널과 이리게이션(irrigation) 채널을 구비한다. 이리게이션 채널은 환부 세척용 수액을 주입 및 배출하는 용도로 사용된다. 워킹 채널은 치료 기구가 삽입되는 용도로 사용된다. 워킹 채널을 통해서 고주파 치료 장치가 삽입되기도 하고 조직을 절개하기 위한 치료 장치가 삽입되기도 한다. Endoscopy that is conventionally used for spinal surgery has the structure of such a catheter. Conventional endoscopes for the spine have a working channel and an illumination channel as well as a lens and an optical fiber channel. Irrigation channels are used for injecting and discharging affected sap. The working channel is used for the purpose of inserting a therapeutic instrument. Radiofrequency treatment devices may be inserted through the working channel or treatment devices for cutting tissue may be inserted.

이와 같은 종래의 척추용 내시경은 매번 세척 및 소독 후에 재사용된다. 상술한 바와 같이 종래의 척추용 내시경에는 워킹 채널, 이리게이션 채널 등의 적어도 하나 이상의 채널이 형성되어 있기 때문에 척추용 내시경을 세척 및 소독하는 것은 번거롭고 어려운 작업이다. 채널은 길고 가느다란 관의 형태로 형성되어 있으므로 그 내부의 오염 물질과 세균을 세척하고 소독하는 것은 쉽지 않다. 척추용 내시경의 세척과 소독이 완전히 이루어지지 않은 상태로 재사용하는 경우 환자가 세균에 노출되어 감염될 수 있는 위험이 있다. This conventional endoscope for the spine is reused after each wash and disinfection. As described above, since at least one channel such as a working channel and an erosion channel is formed in the conventional endoscope for the spine, cleaning and disinfecting the endoscope for the spine is cumbersome and difficult. Since the channels are formed in the form of long, thin tubes, it is not easy to clean and disinfect the contaminants and bacteria inside them. If the endoscope for the spine is reused without complete cleaning and disinfection, the patient may be exposed to bacteria and become infected.

특히, 워킹 채널을 통해 여러 차례 치료 기구를 삽입하는 작업을 수행하면, 워킹 채널 내부에 흠집이 발생하여 그 부분에 오염물질이나 세균이 누적될 위험이 높아진다. In particular, when the treatment device is inserted through the working channel several times, scratches are generated inside the working channel, thereby increasing the risk of contaminants or bacteria accumulating therein.

따라서, 상술한 바와 같은 종래의 척추용 내시경과 달리 세척 및 소독이 용이한 구조를 가지며 일부 구조는 일회용으로 사용한 후에 소독하지 않고 버릴 수 있는 구조를 가진 척추 내시경용 카테처 장치가 필요하다.Therefore, unlike the conventional endoscope for the spine as described above has a structure that is easy to clean and disinfection, some structures need a endoscopic catheter device having a structure that can be discarded without disinfection after use for single use.

또한, 종래의 척추용 내시경 카테터의 내시경은 렌즈와 영상 장치가 연결된 비교적 고가의 장치이므로 매번 세척 및 소독 후 재사용할 수 밖에 없는 문제점이 있다. 이와 같은 문제점을 해결하기 위하여 내시경의 적어도 일부 구성이라도 사용후에 세척하지 않고 교체하여 사용할 수 있는 구조를 가진 척추용 내시경 카테터가 필요하다.In addition, the endoscope of the conventional spinal endoscope catheter is a relatively expensive device connected to the lens and the imaging device, there is a problem that can only be reused after each cleaning and disinfection. In order to solve such a problem, there is a need for an endoscope catheter for a spine that has a structure that can be used without replacing at least a part of the endoscope without washing.

본 발명은 상술한 바와 같은 필요성을 고려하여 안출된 것으로, 비교적 저가로 제작 가능한 일부 구성은 일회용으로 교체 사용이 가능하고 재사용하는 구성은 세척 및 소독이 용이한 구조를 가진 내시경용 카테터 조립체를 제공하는 것을 목적으로 한다.The present invention has been made in view of the necessity as described above, and some components that can be manufactured at a relatively low cost can be replaced and used for a single use and reused components provide an endoscope catheter assembly having a structure that is easy to clean and disinfect. For the purpose of

상기 목적을 달성하기 위한 본 발명의 내시경용 카테터 조립체는, 치료 기구를 삽입할 수 있도록 형성된 워킹 채널과, 환부를 관찰할 수 있는 내시용 렌즈를 삽입할 수 있도록 형성된 내시경 채널을 구비하고 길이 방향으로 연장되도록 형성되는 카테터 몸체; 및 사용자가 손으로 잡을 수 있도록 형성되고 상기 카테터 몸체가 결합되는 카테터 핸들;을 포함하는 점에 특징이 있다.Endoscope catheter assembly of the present invention for achieving the above object, the working channel formed to insert the treatment instrument, and the endoscope channel formed to insert the endoscope lens to observe the affected area in the longitudinal direction A catheter body formed to extend; And a catheter handle formed to be held by the user by the hand and to which the catheter body is coupled.

본 발명에 따른 내시경용 카테터 조립체는, 일부 구성을 일회용으로 교체하여 사용하기 용이하도록 구성함으로써, 세척 및 소독의 불편함을 최소화하고 환부의 오염에 의한 환자의 위험을 최소화할 수 있는 장점이 있다. The endoscope catheter assembly according to the present invention has an advantage of minimizing the discomfort of cleaning and disinfection and minimizing the risk of the patient due to contamination of the affected part by configuring some components to be disposable and easy to use.

한편, 도 5를 참조하면 카테터 몸체(100)의 내시경 채널(110)의 단부에는 투명 재질의 렌즈 커버(500)가 설치된다. 렌즈 커버(500)는 렌즈 튜브(300)를 보호하면서 빛을 통과시켜 렌즈 튜브(300)를 통해 환부를 관찰 가능하게 한다. Meanwhile, referring to FIG. 5, a transparent lens cover 500 is installed at an end portion of the endoscope channel 110 of the catheter body 100. The lens cover 500 may pass through the light while protecting the lens tube 300 so that the affected part may be observed through the lens tube 300.

이하, 상술한바와 같이 구성된 내시경용 카테터 조립체의 사용방법에 대해 설명한다. Hereinafter, a method of using the endoscope catheter assembly configured as described above will be described.

도 1 및 도 2에 도시한 것과 같이 렌즈 튜브(300)를 카테터 몸체(100)의 내시경 채널(110)에 밀어 넣고 카테터 핸들(200)과 내시경 핸들(400)을 서로 가압하여 결합한다. As shown in FIGS. 1 and 2, the lens tube 300 is pushed into the endoscope channel 110 of the catheter body 100, and the catheter handle 200 and the endoscope handle 400 are pressed to each other.

이와 같은 상태에서 카테터 몸체(100)를 별도의 유도관 등을 이용하여 환자의 체내 환부에 밀어 넣는다. 이때, 조명기구를 조명 연결부(220)에 고정하고 빛을 발생시키면 투명 재질로 형성된 카테터 몸체(100)를 통해 빛이 환부로 전달되어 환부를 비추게 된다. 카테터 몸체(100)에 조명광을 효과적으로 전달하기 위해 조명 연결부(220)는 카테터 몸체(100)와 접촉하는 투명 재질의 조명 전달부를 구비할 수도 있다. In this state, the catheter body 100 is pushed into the patient's body affected area using a separate guide tube. At this time, when the lighting fixture is fixed to the light connecting portion 220 and generates light, the light is transmitted to the affected part through the catheter body 100 formed of a transparent material to reflect the affected part. In order to effectively transmit the illumination light to the catheter body 100, the lighting connection 220 may be provided with a light transmission of a transparent material in contact with the catheter body (100).

이와 같은 상태에서 카테터 몸체(100)의 이리게이션 채널(131, 132)을 통해 수액을 주입 및 배출하면 환자의 환부 부분이 세척되면서 렌즈 커버(500)를 통해서 시술자가 효과적으로 환부를 관찰할 수 있다. 렌즈 커버(500)와 내시경 렌즈(310)를 통해 획득된 영상은 렌즈 튜브(300)의 광섬유 채널(320)을 통해 내시경 핸들(400)의 영상 처리기(420)로 전달된다. 영상 처리기(420)에 연결단자를 연결하여 영상 처리기(420)와 표시장치를 연결하면 전기 신호가 표시 장치에 전달되어 환부 영상을 표시 장치에 표시하게 된다. 시술자는 서로 결합된 카테터 핸들(200)과 내시경 핸들(400)을 한손으로 움직이면서 용이하게 환부의 영상을 확인할 수 있다. In such a state, when the fluid is injected and discharged through the guiding channels 131 and 132 of the catheter body 100, the affected part of the patient is washed, and the operator can effectively observe the affected part through the lens cover 500. The image obtained through the lens cover 500 and the endoscope lens 310 is transmitted to the image processor 420 of the endoscope handle 400 through the optical fiber channel 320 of the lens tube 300. When the connection terminal is connected to the image processor 420 to connect the image processor 420 to the display device, an electrical signal is transmitted to the display device to display the affected image on the display device. The operator can easily check the image of the affected part while moving the catheter handle 200 and the endoscope handle 400 coupled to each other with one hand.

이와 같은 상태에서 환부에 대해 조직을 절개하거나 고주파 치료를 하거나 약물을 주입할 필요가 있으면, 한손으로 카테터 핸들(200)과 내시경 핸들(400)을 동시에 잡은 상태에서 다른 한손으로 다른 치료 기구를 카테터 몸체(100)의 워킹 채널(120)을 통해 밀어 넣어서 시술을 진행한다. If it is necessary to incision tissue, high frequency treatment, or inject the drug in the affected state in this state, while holding the catheter handle 200 and the endoscope handle 400 with one hand at the same time, the other treatment device with the other hand with the catheter body The procedure is performed by pushing through the working channel 120 of 100.

As described above, since the user can manipulate the endoscope catheter assembly according to the present embodiment in a state in which the catheter handle 200 and the endoscope handle 400 are coupled to each other, the other hand is inserted into the working channel 120. There is an advantage that can easily handle the treatment device being. This enables the operator to operate the endoscope alone and the treatment apparatus alone without the help of other assistants, which has the advantage that the diagnosis and treatment of the affected part of the patient can be performed more conveniently and precisely.

또한, 카테터 몸체(100)와 카테터 핸들(200) 부분은 비교적 적은 비용으로 제작하는 것이 가능하므로 일회용으로 사용하는 것이 가능하다. 이와 같이 카테터 몸체(100)와 카테터 핸들(200)을 일회용으로 제작 및 사용함으로써 재사용을 위한 세척의 필요성이 없어졌으므로 환자의 감염 가능성을 원천적으로 차단할 수 있고 세척을 위한 병원의 부담도 줄일 수 있는 장점이 있다. In addition, since the catheter body 100 and the catheter handle 200 can be manufactured at a relatively low cost, the catheter body 100 and the catheter handle 200 can be used for single use. As such, since the catheter body 100 and the catheter handle 200 are manufactured and used for single use, the necessity of washing for reuse can be eliminated, thereby preventing the infection of the patient at the source and reducing the burden on the hospital for washing. There is this.

렌즈 튜브(300) 및 내시경 핸들(400) 부분은 렌즈와 영상처리기를 구비하므로 카테터 몸체(100)와 카테터 핸들(200) 부분에 비해 제조 단가가 높은 편이다. 따라서, 렌즈 튜브(300) 및 내시경 핸들(400) 재사용하는 것이 바람직하다. 본 실시예에 따른 내시경용 카테터 조립체의 렌즈 튜브(300) 및 내시경 핸들(400)은 단순한 구조로 되어 있다. 특히 렌즈 튜브(300) 부분에는 카테터 몸체(100)에 형성된 것과 같은 이리게이션 채널(131, 132)과 워킹 채널(120)과 같은 채널이 형성되어 있지 않으므로, 종래의 내시경의 구조에 비해 소독 및 세척이 편리하고 용이한 구조로 되어있다. 렌즈 튜브(300)의 외부만 세척액 및 소독액으로 닦는 것만으로 쉽게 렌즈 튜브(300)를 세척 및 소독할 수 있으므로, 병원의 사용상의 불편함도 없고 불필요한 감염에 노출되는 환자의 위험도 대폭 낮출 수 있는 장점이 있다. 이로 인해 렌즈 튜브(300) 및 내시경 핸들(400)의 사용 수명도 연장할 수 있으므로, 전체적인 치료 원가를 낮출 수 있는 장점이 있다.Since the lens tube 300 and the endoscope handle 400 are provided with a lens and an image processor, the manufacturing cost is higher than that of the catheter body 100 and the catheter handle 200. Therefore, it is desirable to reuse the lens tube 300 and the endoscope handle 400. The lens tube 300 and the endoscope handle 400 of the endoscope catheter assembly according to the present embodiment have a simple structure. In particular, the lens tube 300 is not formed in the channel, such as the channel (131, 132) and the working channel 120 formed in the catheter body 100, disinfection and cleaning compared to the structure of the conventional endoscope This is a convenient and easy structure. Since only the outside of the lens tube 300 can be easily cleaned and disinfected by cleaning and disinfectant solution, there is no inconvenience in using a hospital and a significant reduction in the risk of a patient exposed to unnecessary infection. There is this. As a result, the service life of the lens tube 300 and the endoscope handle 400 may also be extended, thereby lowering the overall treatment cost.

또한, 부주의로 인해 렌즈 튜브(300)의 외면에 오염 물질 또는 세균이 묻어 있더라도 환자의 감염 위험을 최소화할 수 있는 장점이 있다. 렌즈 튜브(300)는 내시경 몸체의 내시경 채널(110)에 삽입되어 사용되므로, 렌즈 튜브(300)는 환자의 조직과 직접 접촉하지 않게 된다. 일회용으로 사용하는 카테터 몸체(100)는 최초 사용시에 멸균 소독이 용이하므로, 만에 하나 렌즈 튜브(300)가 일부 오염되어 있다 하더라도 환자에 영향을 미칠 가능성은 대폭 감소하는 장점이 있다.In addition, even if the contamination or bacteria on the outer surface of the lens tube 300 due to carelessness has the advantage of minimizing the risk of infection of the patient. Since the lens tube 300 is inserted into the endoscope channel 110 of the endoscope body and used, the lens tube 300 does not directly contact the tissue of the patient. Since the catheter body 100 for single use is easy to sterilize at first use, even if the lens tube 300 is partially contaminated, the possibility of affecting the patient is greatly reduced.
