| Research Abstract |
We developed a thin needle driver with multiple degrees of freedom for neonatal endoscopic surgery and evaluated its efficacy compared with a conventional needle driver.
Suturing, the direction of which was parallel to the insertion direction of the instrument, on a horizontal plane set in a box trainer using the novel needle driver was completed shorter than that using the conventional needle driver. Multi-directional suturing on a vertical plane set in the box trainer using the novel needle driver was less invasive to the object and showed more ideal needle trajectories compared to that using the conventional needle driver. The novel needle driver could be used without any trouble even in vivo experiments using rabbits.
