Multi-mode information fusion navigation system for robot-assisted vascular interventional surgery

Abstract

Background Minimally invasive vascular intervention (MIVI) is a powerful technique for the treatment of cardiovascular diseases, such as abdominal aortic aneurysm (AAA), thoracic aortic aneurysm (TAA) and aortic dissection (AD). Navigation of traditional MIVI surgery mainly relies only on 2D digital subtraction angiography (DSA) images, which is hard to observe the 3D morphology of blood vessels and position the interventional instruments. The multi-mode information fusion navigation system (MIFNS) proposed in this paper combines preoperative CT images and intraoperative DSA images together to increase the visualization information during operations. Results The main functions of MIFNS were evaluated by real clinical data and a vascular model. The registration accuracy of preoperative CTA images and intraoperative DSA images were less than 1 mm. The positioning accuracy of surgical instruments was quantitatively assessed using a vascular model and was also less than 1 mm. Real clinical data used to assess the navigation results of MIFNS on AAA, TAA and AD. Conclusions A comprehensive and effective navigation system was developed to facilitate the operation of surgeon during MIVI. The registration accuracy and positioning accuracy of the proposed navigation system were both less than 1 mm, which met the accuracy requirements of robot assisted MIVI.

Digital Technology Competencies of Medical Faculty Students in the Process of Digitalisation in Healthcare: Perceptions and Willingness

“…Dijitalleşmenin, sağlık sektörü ve beraberinde hekimlerin rolünü dönüştüreceği ön görülmektedir (6). Yapay zeka, büyük veri, robotik gibi teknolojilerin sağlık hizmetlerinde uygulanması ile birlikte çok daha hızla ilerleyen dijitalleşme süreci; hastalık tahminini, sınıflandırması ve teşhisi noktasında hem hastalara hem de sağlık profesyonellerine fayda sağladığı yönündeki çalışmalarda hız kazanmaya başlamıştır (7)(8)(9)(10). Bu noktada çözülmemiş birçok soruna rağmen, tıbbın dijital dönüşümünün; teknolojik yetenekler aracılığıyla, insanların yaşam kalitesini artırmak ve sağlık hizmetlerini demokratikleştirmek için klinik sonuçları iyileştireceğine dair umut vaat ettiği görülmektedir (11).…”

Performance Evaluation of a Vascular Interventional Surgery Robotic System with Visual-Based Force Feedback

“…These systems can prevent surgeons from being exposed to X-ray radiation from the digital subtraction angiography (DSA) equipment and improve the operating environment of surgeons. With the help of the robot-assisted remote intervention system, the surgeon can sit in a comfortable seat in the control room outside the operating room and perform surgery by remotely controlling the vascular interventional robot by watching advanced medical imaging equipment [3,4]. This remote robot-assisted interventional technology has a tremendously positive effect on improving the surgeon's operating experience, increasing the utilization rate of surgeons, prolonging the professional life of surgeons, and improving the uneven distribution of medical resources [4,5].…”

“…It also improved surgical accuracy and stability compared manual techniques [7][8][9]. This technology effectively filters out the jitter that occurs when the surgeon's hands interact with the device [10] and expands the surgeon's field of vision [3,11].…”

“…Reduce the distance 𝐿 appropriately to ensure that the catheter maintains a certain rigidity within this distance. 3 Adopt methods that utilize a certain degree of rigidity of the catheter to advance the catheter continuously. For method 1, these methods [55,[58][59][60][61][62][63][64][65] passively support mechanisms for buckling prevention.…”
