Description

악교정 수술장치Orthognathic surgical device
본 발명은 악교정 수술장치에 관한 것으로, 더욱 상세하게는, 환자의 미간에 흉터를 남기지 않음은 물론이고 커팅 라인을 따라 안정적으로 상악을 분할하고 다듬질 기준 평면에 따라 안정적으로 상악을 다듬질할 수 있게 가이드함으로써, 양악 수술에 대한 정확도 및 신속도를 향상시킬 수 있는 악교정 수술장치에 관한 것이다.The present invention relates to an orthognathic surgical device. More specifically, the present invention relates to an orthognathic surgical device, and more specifically, a guide that not only leaves no scar between the patient's eyebrows, but also stably divides the upper jaw along the cutting line and stably trims the upper jaw according to the trimming reference plane. By doing so, it relates to an orthognathic surgical device that can improve the accuracy and speed of orthognathic surgery.
악교정 수술(orthognathic surgery)은 일반적으로 구조, 성장, 수면 무호흡증(sleep apnea), 부정합들과 관련된 안면 및 턱의 상태들을 바로잡기 위해서 또는 치과교정(orthodontic) 문제들을 바로잡기 위해서 시술된다. Orthognathic surgery is generally performed to correct facial and jaw conditions related to structure, growth, sleep apnea, malalignment, or to correct orthodontic problems.
예를 들어, 상당히 후퇴된 상부 턱 또는 개방 교합(open bite)을 가지는 사람은 상악골 골절술(maxillary osteotomy)을 받는 것이 좋을 것이다.For example, people with a significantly retruded upper jaw or an open bite may benefit from a maxillary osteotomy.
이러한 상악골 골절술은 먼저 양안와(eye socket) 아래를 절개하여 상악골의 세그먼트화된(segmented) 부분을 상악골의 온전한(intact) 부분으로부터 분리하며, 이 경우 입천장과 모든 상부 치아들을 포함하는 전체 세그먼트화된 부분이 단일 유닛으로서 이동가능하게 된다. 이와 같이, 세그먼트화된 부분은 상부 및 하부 치아가 서로 적절하게 들어맞을 때까지 이동된 후에, 작은 스크류들 및 플레이트들을 이용하여 두개골에 결착 고정되며, 이는 자연적인 골절 재생(bone healing)이 이루어질 때까지 고정된다.This maxillary osteotomy first involves making an incision below both eye sockets to separate the segmented portion of the maxilla from the intact portion of the maxilla, in this case the entire segmented portion including the palate and all upper teeth. The part becomes movable as a single unit. In this way, the segmented portion is moved until the upper and lower teeth fit together properly and then fixed to the skull using small screws and plates, allowing natural bone healing to occur. It is fixed until
이와 같은 상악골 골절술을 시행하는 의사는 3D CT 데이터를 기반으로 수술 시뮬레이션을 실시하고, 상하악 삭제 및 이동량을 확인하여 환자에게 적용한다. 상기 시뮬레이션 상태로 수술하기 위해 환자 미간에 미세 바늘 형태의 와이어(K-WIRE)를 식립하고 상악의 삭제할 부분을 선(CUTTING LINE)으로 표시한 후에, 삼각함수를 이용하여 제거영역을 계산한 후 적용하는 방식을 이용하였다. 이러한 시술방식은 환자 미간에 K-WIRE 핀을 식립함에 따른 흉터를 야기시켰고, 정교합 정확성이 의사의 역량에 따라 크게 좌우되는 문제가 있었다. A doctor who performs such a maxillary bone osteotomy performs a surgical simulation based on 3D CT data, checks the amount of preparation and movement of the upper and lower jaw, and applies it to the patient. In order to perform surgery in the above simulation state, a fine needle-shaped wire (K-WIRE) is placed between the patient's eyebrows, the part of the maxilla to be removed is marked with a line (CUTTING LINE), and the area to be removed is calculated using trigonometric functions and then applied. method was used. This treatment method caused scarring due to the placement of the K-WIRE pin between the patient's eyebrows, and there was a problem in that the accuracy of precise alignment was greatly dependent on the doctor's capabilities.
또한, 이러한 수동에 의한 작업은 수술시간을 지연시켰고, 수술시간의 지연은 환자의 출혈량 및 스트레스에 직결되어 수술에 대한 만족도를 저하시키는 원인이 되었다.In addition, this manual work delayed the surgery time, and the delay in the surgery time was directly related to the amount of bleeding and stress of the patient, causing a decrease in satisfaction with the surgery.
