본 발명은 인체 관절의 움직임을 모사할 수 있는 관절 시뮬레이터에 관한 것으로, 더욱 상세하게는 의료영상장비를 통해 관절 운동에 따른 관절의 내부 조직에 대한 촬영이 가능한 의료영상장비 내에서 구동 가능한 관절 시뮬레이터에 관한 것이다.The present invention relates to a joint simulator capable of simulating the movement of a human joint, and more particularly, to a joint simulator that can be driven in a medical imaging apparatus capable of recording the internal tissue of the joint according to the joint movement through the medical imaging equipment. It is about.
인체 관절의 다양한 관절 병증 치료를 위해서는 다양한 상황에서의 관절 거동 연구가 필요하다. 이러한 관절 거동 연구에 생체역학이 이용될 수 있다.In order to treat various arthrosis of human joints, research on joint behavior in various situations is required. Biomechanics can be used to study these joint behaviors.
생체역학은 생체시스템을 이해하기 위해 역학적 원리를 이용하는 학문 분야로서 기계공학의 재료역학, 동역학, 유체역학의 원리와 방법을 주로 사용한다. 특히 근골격계 생체역학 연구에 있어서 관절의 운동과 관절에 작용하는 힘·모멘트를 다루는 운동학(kinematics)과 운동역학(kinetics)은 주요한 연구주제이다.Biomechanics is a discipline that uses mechanical principles to understand biological systems. It mainly uses the principles and methods of mechanical, material and fluid mechanics. Especially in the study of musculoskeletal biomechanics, kinematics and kinetics dealing with joint motion and the forces and moments acting on the joints are the main research topics.
관절의 운동은 관절을 둘러싼 여러 근육들의 수축작용으로 발생하며, 관절운동의 순방향에 기여하는 주동근과 역방향에 기여하는 길항근 작용의 합력의 결과이다. 이 합력의 결과가 외관상 운동으로 나타나기 때문에 실제 개별 근육의 힘 조합은 매우 다양할 수 있으며, 개별 근육의 힘을 직접 측정하는 것도 현재 기술로는 불가능하다.Joint movement occurs as a result of the contraction of several muscles surrounding the joint and is the result of the coordination of the antagonist muscles that contribute to the main and reverse directions, which contribute to the forward direction of the joint motion. Since the result of this combined force is apparent in motion, the actual combination of individual muscle forces can vary widely, and direct measurement of individual muscle forces is not possible with current technology.
근골격계 생체역학에서는 이러한 개별 근육의 힘을 계산하기 위해 다양한 방법이 연구되고 있으며, 또한 직접 측정이 불가능한 생체 내 관절의 접촉력과 연골의 응력 등을 연구하기 위한 연구도 진행되고 있다.In musculoskeletal system biomechanics, various methods have been studied to calculate the strength of these individual muscles, and research has been conducted to study the contact force of joints and the stress of cartilage, which cannot be measured directly.
일상 생활 혹은 스포츠 활동 중에 관절과 근육에 작용하는 부하를 예측하는 것은 근골격계 질환을 이해하기 위해서 매우 중요하다. 특히 퇴행성관절염(osteoarthritis)과 같이 발병률도 높고 기전, 치료, 예방 등에 역학의 기여도가 높은 질병의 이해에는 근골격계 생체 역학의 역할이 매우 중요하다.Predicting the load on the joints and muscles during everyday or sporting activities is very important for understanding musculoskeletal disorders. In particular, the role of musculoskeletal biomechanics is very important for understanding diseases such as osteoarthritis, which have high incidence and high contribution to epidemiology, mechanism, treatment, and prevention.
최근에 의료영상 기술의 발전으로 정확한 관절 운동 측정방법들이 제안된 바 있으며, 비침습적으로 생체 내 조직의 특성들을 측정할 수 있는 방법 등도 계속 발전하고 있다. 하지만 관절의 동역학적 파라미터나 응력 등을 예측하기에는 한계가 있으며, 3차원 근골격 공학모델을 이용한 융합적 연구 방법이 필요하다. 또한 질병에 따른 생체역학적 변화나 인체의 운동, 스포츠부상에 대한 연구를 진행할 경우 인체의 복잡성을 반영한 근골격계 모델을 이용하는 것이 유용하다.Recently, accurate joint motion measurement methods have been proposed due to the development of medical imaging technology, and methods for measuring non-invasive characteristics of tissues in vivo have been continuously developed. However, there are limitations in predicting the dynamic parameters and stresses of joints, and there is a need for convergent research method using 3D musculoskeletal engineering model. In addition, it is useful to use musculoskeletal models that reflect the complexity of the human body when studying biomechanical changes, human body movements, and sports injuries.
인체의 관절 거동을 분석하는 것은 의료 분야에서 여러 가지 장점이 있다. 첫째는 제작한 인공 관절 디자인이 얼마나 실제로 잘 작동하는지 측정할 수 있게 한다. 둘째는 해석을 통하여 관절의 수술과정과 수술결과가 얼마나 잘 될지 예측 할 수 있다. 셋째는 관절의 퇴행성 질환에 작용하는 하중의 작용을 이해하여 이를 예방할 수 있다.Analyzing the joint behavior of the human body has several advantages in the medical field. The first is to measure how well the artificial joint design works. Second, the interpretation can predict how well the joint operation and the outcome of the joint will be performed. Third, by understanding the effect of the load on the degenerative disease of the joint can be prevented.
그런데 종래의 관절 거동 분석을 위한 장비들은 관절의 움직임만 모사할 수 있었고, 정작 중요한 관절 내부의 조직들의 변형 양상에 대한 관찰이 불가능한 문제점이 있다.However, the conventional equipment for analyzing the behavior of the joint could only simulate the movement of the joint, there is a problem that it is impossible to observe the deformation of the tissue inside the important joint.
