Finite Element Analysis on Blood Vessels: Understanding Clipping Phenomenon

Background: Blood vessels clipping is one of medical interventions that could close any blood vessels rupture in several major conditions, such as heart attack and stroke hemorrhage. Besides coil, the aneurysm clip is one of the medical tools for clipping the vessels. In its development, the clip surface has been limited to discuss, while the configuration of the clip surface holds an important factor. Aims: This study aims to design the surface of surgical clip as well as understanding the clipping phenomenon on the intended blood vessels using the finite element method. Shortened Method: The blood vessel was clamped between two surfaces of surgical clips. This analogy was then simulated using finite element study with a set of constraints and load from 1 to 5N. Results: The load and constraint of 1N results in Von Misses Stress (VMS) less than the Young Modulus of the blood vessels material. Conclusion: It can be concluded that the new design of surgical clip’s surface must have final closing force around 1N to avoid any failure during clamping, such as rupture, slicing, and slip. Implication: This study is significantly helping the manufacturer of surgical clip to have further development regarding the surface profile of surgical clips.
