Description

두개골편 고정 장치cranial fragment fixation device
본 발명은 두개골편 고정 장치에 관한 것으로서, 상세하게는 머리에 손상을 입거나 질환이 있는 환자의 머리 수술이 완료된 후 절개된 두개골편이 환자의 두개골과 봉합하여 고정되도록 하는 두개골편 고정 장치에 관한 기술이다.The present invention relates to a cranial fragment fixing device, and more particularly, to a cranial fragment fixing device for fixing an incised cranial fragment with a patient's skull by sutures after head surgery of a patient with a head injury or disease is completed. to be.
일반적으로 머리에 손상을 입거나 뇌질환이 있는 환자는 두개골을 절개한 후 두개골의 내면에 있는 뇌 수술을 진행한다.In general, a patient with a head injury or a brain disease performs brain surgery on the inner surface of the skull after an incision is made in the skull.
이러한 두개골을 절개하여 이루어지는 수술은 환자의 환부에서 가장 가까운 두개골을 절개하여 절개된 두개골편을 분리시킨 후 절개된 부분을 통해 환자에게 필요한 수술을 실시한 뒤 분리된 두개골편을 환자의 두개골에 다시 봉합하여 고정하여 수술을 마무리한다.Surgery performed by incision of the skull is performed by incision of the skull closest to the patient's affected area, separating the incised skull fragment, performing the necessary surgery on the patient through the incision, and then suturing the separated skull fragment back to the patient's skull. Fix and complete the operation.
상기한 것과 같이 두개골을 절개하여 이루어지는 수술의 경우 절개된 두개골편을 환자의 두개골에 다시 봉합하는 방법으로는 두개골에 구멍을 내고 철사를 조여서 고정하거나 고정용 철판을 대고 철판에 뚫려있는 구멍으로 고정 나사를 두개골에 박아서 고정하는 방법이 사용되었다.In the case of surgery performed by incision of the skull as described above, as a method of suturing the incised skull piece to the patient's skull again, a hole is made in the skull and the wire is tightened to fix it, or a fixing screw is put through a hole drilled in the iron plate by applying a fixing iron plate. The method of fixing by inserting into the skull was used.
그러나, 철사를 이용한 고정장치는 각각의 골편에 다수의 구멍을 뚫어야 하는 위험이 있고 비교적 장시간이 소요된다는 단점이 있고, 고정용 철판과 고정 나사를 사용하는 경우 수술후 회복 단계에서 수술 경과의 확인을 위한 MRI(자기공명영상)을 촬영시 고정 나사가 있는 부분의 이미지가 선명하게 촬영되지 못하여 정확한 수술 경과를 파악하기 어렵다.However, the fixing device using a wire has the disadvantage of having to drill a large number of holes in each bone fragment and taking a relatively long time. When taking an MRI (magnetic resonance imaging), the image of the part with the fixing screw cannot be taken clearly, so it is difficult to understand the exact surgical procedure.
이러한 문제점을 해결하기 위한 것으로 미국 등록특허 제9265530호가 개시되어 있다.In order to solve this problem, US Patent No. 9265530 is disclosed.
상기 종래기술의 경우 두개골편을 고정시키는 장치를 금속 재질을 사용하지 않고 제작하고, 지지 플레이트와 클로저 플레이트에 의해 두개골과 두개골편의 고정이 완료된 후 지지 플레이트와 클로저 플레이트를 가압하는 구성들을 가위 등을 이용하여 절단하여 간편하게 두개골편 고정 장치의 시술을 마무리할 수 있는 것이다.In the case of the prior art, the device for fixing the skull piece is manufactured without using a metal material, and after the fixing of the skull and the skull piece is completed by the support plate and the closure plate, the components for pressing the support plate and the closure plate are using scissors, etc. By cutting it, it is possible to easily complete the procedure of the skull fragment fixing device.
그러나, 상기한 종래기술의 경우 두개골편을 고정시키는 장치의 설치를 완료한 후 불필요한 부품의 절단을 위하여 가위 등의 날카로운 부재를 사용함에 따라 시술의 위험성이 존재하며, 불필요한 부품의 제거 과정이 신속하지 못하여 신속한 시술이 어려운 문제점이 있었다.However, in the case of the prior art described above, there is a risk of surgery as a sharp member such as scissors is used to cut unnecessary parts after installation of the device for fixing the skull fragment is completed, and the process of removing unnecessary parts is not rapid. Therefore, there was a problem that it was difficult to perform a prompt operation.
따라서, 두개골편을 두개골에 봉합함에 있어서 금속 재질을 사용하지 않으면서도 짧은 시간에 봉합이 가능한 두개골편 고정 장치의 개발이 필요한 실정이다.Therefore, there is a need to develop a cranial fragment fixing device that can be sutured in a short time without using a metal material in suturing the skull fragment to the skull.
