Description

치과용 리트랙터Dental Retractor
본 발명은 치과용 리트랙터에 관한 것으로 보다 자세하게는 필요에 따라 굽힘 변형이 용이하고, 일정조건하에 원래의 형상으로 돌아오도록 형상기억특성의 재질을 포함하고 넓은 면적의 조직을 효과적으로 고정시킬 수 있는 치과용 리트랙터에 관한 것이다.The present invention relates to a dental retractor, and more particularly, to bend and deformation as needed, including a material of the shape memory characteristics to return to the original shape under a certain condition and can effectively secure a large area of tissue It relates to a retractor.
임플란트 또는 기타 치과의 외과적인 시술 시 시야를 충분히 확보하기 위해 상악 또는 하악의 입술을 젖혀 환자의 입을 크게 벌리게 한 상태에서 진료를 실시하는 것이 일반적이다.It is common practice to hold the patient's mouth wide open with the maxillary or mandibular lip open to ensure sufficient visibility during surgical procedures of implants or other dental procedures.
이와 같이, 환자의 입을 벌리고 진료를 하는 과정에서 치아의 뿌리 등을 치료하기 위하여 이를 덮고 있는 잇몸 조직을 절개했을 때, 그 잇몸 조직을 제대로 잡아주지 않는 경우 진료에 상당한 지장을 초래하게 된다. 이러한 이유로 다양한 치과 진료 또는 수술 시, 환자의 구강 내의 시야를 확보하고 원활한 작업 수행을 위해 치아를 덮는 잇몸 조직을 고정할 수 있도록 리트랙터(retractor)를 사용하고 있다.As such, when the gum tissue covering the tooth is dissected in order to treat the root of the tooth, etc. in the process of opening the patient's mouth, if the gum tissue is not properly grasped, it causes significant obstacles in the treatment. For this reason, a retractor is used to secure the view of the patient's mouth in various dental procedures or surgery and to fix the gum tissue covering the teeth for smooth operation.
일반적으로 사용되는 리트랙터는, 소정의 두께를 가진 금속 와이어가 프레임의 형태를 이루고 있는 구조체로서, 예를 들어, 손잡이부와 잇몸 조직을 잡아주는 역할을 하는 견인부로 형성된다.The retractor generally used is a structure in which a metal wire having a predetermined thickness forms a frame. For example, the retractor is formed of a retractor that serves to hold a handle part and gum tissue.
이러한 일반적인 리트랙터는, 일반적인 금속 재료로 이루어져 있어 형태의 변형이 용이하지 않아, 환자의 입을 벌린 상태에서 한번 장착되면 리트랙터의 이동이 용이하지 않아 수술시 공간적인 제약을 주는 문제점이 있다.Since the general retractor is made of a general metal material, the shape of the retractor is not easy to be deformed, and once mounted in a state where the patient's mouth is open, the retractor is not easily moved, thereby causing a space limitation during surgery.
또한, 일반적인 리트랙터는 전단부의 크기가 한정되어 보통 하나의 치아를 덮는 정도의 크기의 잇몸 조직만을 고정시킬 수 있어, 복수의 치아를 덮는 넓은 면적의 잇몸조직을 고정시킬 필요가 있는 경우에는 그 사용에 제한이 따르는 문제점이 있다.In addition, the general retractor is limited in the size of the front end portion can be fixed only the gum tissue of a size that usually covers a single tooth, if the need to fix a large area of gum tissue covering a plurality of teeth, the use There is a problem with the limitation.
그러므로, 복수개의 치아 또는 그 잇몸을 수술하는 경우에 넓은 면적의 잇몸 조직을 한꺼번에 지탱할 수 있으면서, 수술 시 시야를 충분히 확보하며 공간적인 제약을 최대한 줄일 수 있도록 쉽게 구부러지는 특성을 가지는 리트랙터의 개발이 필요하다.Therefore, in the case of operating a plurality of teeth or gums, it is possible to support a large area of gum tissue at the same time, and to develop a retractor having a characteristic of easily bending to secure sufficient field of vision during surgery and to reduce spatial constraints as much as possible. need.

Dental retractor 1 according to an embodiment of the present invention is an example of a surgical retractor used mainly in the surgical operation in the dentist, is a mechanism that serves to hold the tissue located in the necessary portion during surgery. Such a tissue will mainly be gum tissue, but the present invention is not limited thereto. The dental retractor 1 may be variously employed when it is necessary to fix the tissue in various operations performed in the dentist.
본 발명에 따른 치과용 리트랙터(1)는 손잡이부(100) 및 견인부(200)를 포함한다. 보다 자세한 설명을 위해 도 1을 제시한다.The dental retractor 1 according to the present invention includes a handle part 100 and a traction part 200. 1 is shown for more detailed description.
도 1은 본 발명의 일 실시예에 의한 치과용 리트랙터(1)를 개략적으로 도시한 도면이다.1 is a view schematically showing a dental retractor 1 according to an embodiment of the present invention.
손잡이부(100)는 길이방향으로 길게 형성되며, 수술시에 손으로 치과용 리트랙터(1)를 지탱하는 손잡이 부분에 해당한다. 이러한 손잡이부(100)의 일단에는 수술 시 절개한 피부 조직을 고정시켜주는 견인부(200)가 형성된다. 한편, 손잡이부(100)의 타단에는 연결구멍(110)이 형성될 수 있고, 상기 연결구멍(110)을 통하여 별도의 손잡이 부분이나 기타 다른 요소들이 채결될 수 있다. Handle portion 100 is formed long in the longitudinal direction, and corresponds to the handle portion for supporting the dental retractor (1) by hand during surgery. At one end of the handle portion 100 is formed a traction unit 200 for fixing the cut skin tissue during surgery. On the other hand, the other end of the handle portion 100 may be formed with a connection hole 110, a separate handle portion or other elements can be drawn through the connection hole 110.
견인부(200)는 그 일측이 상기 몸체부의 일단에 연결되고 타측이 치아에 지지된다. 이러한 견인부(200)는 수술 시 피부조직을 견인하는 역할을 한다. 보다 자세하게 설명하면, 견인부(200)의 끝단은 치아와 같은 뼈구조 지지되고, 치아를 감싸고 있는 조직을 절개한 경우 견인부(200)는 절개된 조직이 다시 치아를 덮지 않도록 조직을 잡아주는 역할을 하는 것이다. Traction unit 200 is one side is connected to one end of the body portion and the other side is supported on the teeth. The traction unit 200 serves to pull the skin tissue during surgery. In more detail, the end of the traction unit 200 is supported by a bone structure, such as a tooth, and when the tissue surrounding the tooth is cut, the traction unit 200 serves to hold the tissue so that the cut tissue does not cover the tooth again. To do.
또한, 견인부(200)는 손잡이부(100)와 고정되게 연결된 것이 아니고, 견인부(200)와 손잡이부(100)는 서로 상대적인 움직임이 가능하다. 즉 굽힘변형이 가능하고 이에 대하여는 후술한다.In addition, the towing unit 200 is not fixedly connected to the handle unit 100, the towing unit 200 and the handle unit 100 can be moved relative to each other. That is, bending deformation is possible and will be described later.
한편, 손잡이부(100)와 견인부(200)는 일체로 형성되는 것이 바람직하나 이에 한정하는 것은 아니다.On the other hand, the handle portion 100 and the towing portion 200 is preferably formed integrally, but is not limited thereto.
손잡이부(100)와 견인부(200)의 재질은 인력으로 쉽게 구부러지며 아울러, 형상기억특성을 제공하는 니티놀(nitinol)을 포함하는 것이 바람직하다. 다만, 형상기억특성을 제공하는 다양한 재질이 변형 채용될 수 있다. 니티놀은 니켈과 티타늄을 약 절반씩 섞어서 만들어진 비자성 합금으로서, 굽히거나 찌그리는 등 외력에 의하여 변형되어도 일정한 온도 이상으로 가열하거나 물에 담그면 원래의 모습으로 돌아가는 형상기억특성이 있다.The material of the handle part 100 and the traction part 200 may be easily bent by manpower, and may include nitinol, which provides shape memory characteristics. However, various materials that provide shape memory characteristics may be modified. Nitinol is a nonmagnetic alloy made by mixing nickel and titanium in half, and has a shape memory characteristic that returns to its original form when heated or immersed in water over a certain temperature even if it is deformed by external force such as bending or crushing.
본 발명에서 사용되는 니티놀은 50℃ 이상의 온도에서 원래의 형태로 돌아오는 형상기억합금인 것이 바람직하다. 이렇게 손잡이부(100)와 견인부(200)가 형상기억합금인 니티놀로 이루어지는바, 수술 시 필요에 따라 의사는 치과용 리트랙터(1)를 사용함에 있어서 견인부(200)만을 구부려 사용하거나 손잡이부(100)만을 구부려 사용하거나 손잡이부(100)와 견인부(200)를 적절히 구부려 사용할 수 있어 공간확보, 시야확보 등으로 인한 수술의 편의성이 증대될 수 있다. 또한 수술이 끝난 후에는 일정 온도 조건하에 리트랙터(1)가 다시 본래의 형상으로 되돌아 오는바 신속하게 재사용이 가능하다.Nitinol used in the present invention is preferably a shape memory alloy to return to its original form at a temperature of 50 ℃ or more. Thus, the handle portion 100 and the tow portion 200 is made of Nitinol, which is a shape memory alloy, the surgeon uses the retractor 1 by bending only the tow portion 200 as needed during surgery. It can be used by bending only the part 100 or by using the handle part 100 and the traction part 200 as appropriate, it is possible to increase the convenience of surgery due to securing the space, securing the field of view. In addition, after the operation is completed, the retractor 1 returns to its original shape under a predetermined temperature condition, and thus can be quickly reused.
견인부(200)는 지지파트(210)를 포함한다. 이때, 지지파트(210)는 견인부(200)의 끝단에 돌출하여 형성된다. 지지파트(210)는 수술 시에 치아 등의 뼈구조에 접촉하여 치과용 리트랙터(1)를 지지하는 역할을 한다. 이때 뼈구조에는 지지파트(210)가 접촉 삽입될 수 있도록 일정한 홈을 형성할 수 있으며, 그렇지 않고 뼈구조의 겉표면에 지지파트(210)가 바로 접촉할 수도 있다.The towing unit 200 includes a support part 210. At this time, the support part 210 is formed to protrude to the end of the towing unit 200. The support part 210 serves to support the dental retractor 1 in contact with bone structures such as teeth during surgery. At this time, the support structure 210 may be formed in the bone structure so that the support part 210 may be inserted into contact. Otherwise, the support part 210 may directly contact the outer surface of the bone structure.
이때, 견인부(200)는 지지파트(210)가 돌출 형성된 부분과 손잡이부(100)가 연결된 부분을 제외한 양 측이 (bar)의 형상으로 연장되게 형성된다. 즉, 손잡이부(100)와 같은 평면상에서 손잡이부(100)의 길이방향과 수직한 방향으로 길게 연장되게 형성되는 것이다. 견인부(200)의 이러한 형상으로 인하여 치과용 리트렉터(1)는 그 형상이 십자형이 된다. 이러한 구성으로 인하여, 복수개의 치아 또는 그 잇몸을 수술하는 경우에, 견인부(200)의 길게 연장 형성된 부분이 넓은 면적의 잇몸 조직 또는 피부 조직을 한꺼번에 지탱할 수 있다.At this time, the traction unit 200 is formed to extend in the shape of both sides (bar) except for the portion in which the support part 210 is protruding and the handle portion 100 is connected. That is, it is formed to extend in a direction perpendicular to the longitudinal direction of the handle portion 100 on the same plane as the handle portion 100. Due to this shape of the traction part 200, the dental retractor 1 has a cross shape. Due to this configuration, in the case of operating a plurality of teeth or gums thereof, the elongated portion of the traction part 200 can support the gum tissue or skin tissue of a large area at one time.
다만, 조직의 넓은 면적을 지탱할 필요가 없는 경우에는, 견인부(200)가 니티놀로 이루어진 특성상, 견인부(200)의 길게 연장 형성된 부분을 구부려 사용하면 된다. 따라서 다양한 면적의 조직을 지탱할 수 있다.However, when it is not necessary to support a large area of the tissue, the traction part 200 may be used by bending the extended portion of the traction part 200 due to the nature of the nitinol. Therefore, it can support the organization of various areas.
한편, 견인부(200)와 손잡이부(100)가 연결되는 부분의 양측에는 내측으로 파여지게 제 1 굽힘홈(220)이 형성된다. 제 1 굽힘홈(220)의 형상은 다양한 형상이 가능하며, 이러한 제 1 굽힘홈(220)의 형성으로 인하여 견인부(200)가 손잡이부(100)로부터 좀더 잘 구부러질 수 있다. 따라서, 의사는 환자가 입을 벌린 상태에서 입 밖으로 일직선으로 뻗어 나온 치과용 리트랙터(1)의 손잡이부(100)를 위 또는 아래 방향으로 굽힘으로써, 수술을 위한 공간확보 또는 시야확보를 용이하게 할 수 있다.On the other hand, the first bending groove 220 is formed to be dug inward on both sides of the portion where the traction unit 200 and the handle unit 100 is connected. The shape of the first bending groove 220 may be a variety of shapes, due to the formation of the first bending groove 220 may be more easily bent from the handle portion 100. Therefore, the doctor bends the handle portion 100 of the dental retractor 1 extending straight out of the mouth in the state where the patient is open, to facilitate space or vision for surgery. Can be.
도 2의 도시와 같이 견인부(200)와 손잡이부(100)가 연결되는 부분, 즉 견인부(200)와 손잡이부(100)가 연결되는 부분의 두께는 손잡이부(100)의 두께보다 얇게 형성될 수 있다. 이는 견인부(200)가 손잡이부(100)로부터 좀더 잘 구부러질 수 있게 하기 위함이다.As shown in FIG. 2, the thickness of the portion to which the tow portion 200 and the handle portion 100 are connected, that is, the portion to which the tow portion 200 and the handle portion 100 are connected is thinner than the thickness of the handle portion 100. Can be formed. This is to allow the towing unit 200 to bend more easily from the handle unit 100.
이를 보다 자세히 설명하면, 도 2의 (a)의 도시와 같이, 견인부(200)와 손잡이부(100)가 연결되는 부분부터 두께가 얇아져 견인부(200)의 전체적인 두께가 손잡이부(100)보다 얇게 형성될 수 있다. 또한, 도 2의 (b)의 도시와 같이, 견인부(200)와 연결되지 않은 손잡이부(100)의 다른 일측으로부터 지지파트(210)로 갈수록 그 두께가 점진적으로 얇아지게 형성될 수 있다. 결국 뼈구조에 지지되면서 절개된 조직을 잡아주는 견인부(200)가 손잡이부(100)로부터 쉽게 구부러지는 변형이 가능하다. 따라서 수술의 편의성, 효율성이 증대된다.To describe this in more detail, as shown in FIG. 2A, the thickness of the towing unit 200 becomes thinner from the portion where the towing unit 200 and the handle unit 100 are connected, so that the overall thickness of the towing unit 200 is the handle unit 100. It can be formed thinner. In addition, as shown in (b) of FIG. 2, the thickness of the handle 100 that is not connected to the traction unit 200 may be gradually thinner from the other side toward the support part 210. As a result, it is possible to easily bend from the handle portion 100, the traction unit 200 to hold the incision tissue while being supported by the bone structure. Therefore, the convenience and efficiency of the surgery is increased.
한편, 지지파트(210)의 치아와 만나는 일측은 복수개의 톱니부(211)가 형성되는 것이 바람직하다. 이러한 톱니부(211)는 치아 등의 뼈구조에 접촉될 때 지지파트(210)가 뼈구조에 좀더 확실히 지지될 수 있도록 도와준다. 톱니부(211)의 형상은 삼각형 형상으로 예시하나 이에 한정하는 것은 아니고, 돌기로 형성될 수 있는 다양한 형상이 가능할 것이다.On the other hand, one side that meets the teeth of the support part 210 is preferably formed with a plurality of teeth 211. The tooth part 211 helps the support part 210 to be more firmly supported in the bone structure when contacting the bone structure such as teeth. The shape of the tooth portion 211 is illustrated as a triangular shape, but is not limited to this, various shapes that may be formed as a projection will be possible.
또한, 지지파트(210)의 형상은 뼈구조와 접촉하는 부분이 필요에 따라 바뀔 수 있는데 보다 자세한 설명을 위해 도 3을 제시한다. 도 3은 지지파트(210)의 뼈구조와 접촉하는 일측의 형상을 설명하기 위한 도면이다.In addition, the shape of the support part 210 may be changed as needed in contact with the bone structure is shown in Figure 3 for a more detailed description. 3 is a view for explaining the shape of one side in contact with the bone structure of the support part 210.
도 3의 (a) 또는 (b)의 도시와 같이 지지파트(210)는 견인부(200)로부터 돌출된 길이가 일정하지 않게 비스듬하게 형성될 수 있다. 따라서 뼈구조의 형상에 따라 그에 맞는 지지파트(210)의 형상을 사용하여 수술시 공간확보, 시야확보를 용이하게 할 수 있다.As shown in (a) or (b) of FIG. 3, the support part 210 may be formed to be inclined at an uneven length protruding from the towing unit 200. Therefore, by using the shape of the support part 210 according to the shape of the bone structure it can be easy to secure space during surgery, to secure the field of view.
또는, 도 3의 (c)의 도시와 같이 지지파트(210)의 형상이 M자 형상이 되도록 중앙보다 양 끝단이 더 돌출되도록 지지파트(210)가 형성될 수 있다.Alternatively, as shown in (c) of FIG. 3, the support part 210 may be formed such that both ends protrude more from the center so that the shape of the support part 210 becomes an M shape.
이렇게 다양한 형상의 지지파트(210)는 견인부(200)에 일체로 형성되는 것이 바람직하나, 다양한 형상을 필요에 따라 탈 부착하는 방식 또한 가능할 것이다.Thus, the support part 210 of various shapes is preferably formed integrally with the towing unit 200, it will also be possible to detach the various shapes as needed.
실시예에 따르면, 도 4의 도시와 같이, 지지파트(210)가 견인부(200)로부터 돌출이 시작되는 부분의 양 측에는 내측으로 파여지게 제 2 굽힘홈(230)이 형성될 수 있다. 이러한 구조를 통하여 견인부(200)가 지지파트(210)로부터 좀더 쉽게 구부러질 수 있다.According to the embodiment, as shown in FIG. 4, the second bending grooves 230 may be formed to be dug inwards on both sides of the portion where the support part 210 starts protruding from the traction part 200. Through this structure, the towing unit 200 may be more easily bent from the support part 210.

치과에서 여러 가지 수술을 하는 경우에 환자는 입을 벌리고, 그 상태에서 수술의 대상이 되는 치아 또는 잇몸 부위의 조직을 절개한다. 이렇게 절개된 조직은 수술을 하는 동안에 젖혀진 상태에서 고정되어 있어야 수술이 용이하고 의사의 시야가 확보된다.In the case of various operations at the dentist, the patient opens his mouth, and in this state, the tissue of the tooth or gum region to be subjected to the operation is incised. The tissue thus cut should be fixed in a folded state during surgery to facilitate surgery and to secure a doctor's vision.
따라서, 조직을 절개한 후 조직을 들어올린 또는 내린 상태에서 치아로 예시되는 뼈구조에 톱니부가 형성된 지지파트의 일측을 접촉시킨다. 그리고 손잡이부를 손으로 잡고 들어올리면, 그 재질이 니티놀, 또는 니티놀과 SUS의 합금 재질로 형성된 치과용 리트랙터(1, 3)는 지지파트가 치아에 고정된 상태에서 위로 또는 아래로 구부러지고 그 상태를 유지한다. 이때 견인부에 의해 젖혀진 조직이 고정된다. 치과용 리트랙터(1, 3)의 구부러짐은 견인부와 윙부 등의 다양한 형상과 두께의 차이에 의해 다양한 형상으로 변형이 가능하고, 부분적으로 또는 전체가 모두 변형되는 것이 가능하다. 그리고 치과용 리트랙터(1, 3)의 형상을 자유롭게 변형시키는 것이 가능하므로, 수술시 시야확보와 공간확보를 용이하게 하여 수술의 편의성이 증진된다.Therefore, after dissecting the tissue, one side of the support part in which the teeth are formed is brought into contact with the bone structure exemplified by the teeth in the raised or lowered tissue. When the handle is held by the hand and lifted up, the dental retractors 1 and 3 formed of Nitinol or an alloy of Nitinol and SUS are bent up or down while the support part is fixed to the teeth. Keep it. At this time, the tissue folded over by the towing unit is fixed. The bends of the dental retractors 1 and 3 can be deformed into various shapes by varying shapes and thicknesses such as the traction part and the wing part, and can be partially or entirely deformed. And since it is possible to freely modify the shape of the dental retractors (1, 3), it is easy to secure the field of view and space during surgery to improve the convenience of surgery.
그리고 수술이 끝나면 치과용 리트랙터(1, 3)는 치아에서 제거되고 조직은 다시 원래의 자리로 돌아오며 꿰매진다. 이때 치과용 리트랙터(1, 3)는 니티놀이나 니티놀과 SUS와 같이 굽힘성이 우수한 재질의 합금 재질로 이루어져 있는바 일정한 온도 조건하에서 다시 원래의 형태로 돌아온다. 따라서 다시 다음 수술에 사용될 수 있다.At the end of the surgery, the dental retractor (1, 3) is removed from the tooth and the tissue is sewn back to its original position. At this time, the dental retractor (1, 3) is made of an alloy material of excellent bendability, such as Nitinol or Nitinol and SUS bar back to the original form under a constant temperature conditions. Therefore, it can be used again in the next surgery.
