Cover Story: Endoscopic endonasal surgery is a common procedure for treating pituitary lesions. However, the reduced workspace and lack of tool dexterity hinder the execution of complex surgical tasks such as suturing. In this paper, we propose a robot-assisted stitching method based on an online optimization-based trajectory generation for curved needle stitching and a constrained motion planning framework to ensure safe surgical instrument motion. Experimental evaluations were conducted to compare the proposed method with the use of conventional instruments. Our results demonstrate a noticeable improvement in the stitching success ratio and a high reduction of the interaction forces with the phantom tissue. View this paper.
