In this study, a new 5-degree of freedom parallel-type robot for neurosurgery is developed and investigated for potential application in deep brain surgery (DBS). The neurosurgical robot consists of the base plate, the moving plate, and three limbs (

We present a novel surgical robotic system for spinal fusion that includes a computer-based planning algorithm, O-type bi-planar fluoroscopy, and a surgical robot. The planning system determines a surgical path based on fluoroscopy images or a 3D ima

The pathway to the maxillary sinus area is anatomically curved and narrow. Thus, using the conventional approach based on the straight endoscope and surgical tools, there are some limitations in inspection and treatment of the target legion of the ma

Much attention has not been paid to analysis of the open-loop stability for gravity counter-balancing of parallel mechanisms or closed-chain mechanisms. The open-loop stability is crucial especially in passively counter-balanced mechanisms where no a

BACKGROUND: The biplane fluoroscopy guided robot system (BFRS) was developed for surgical robotic systems, minimally invasive surgeries, and cooperative robotic systems, as well as enhanced surgical planning and navigation with preoperative and intra

This paper proposes a new 4-Degree-of-Freedom (DOF) master-slave system for 3 dimensional needle steering. Both master and slave devices are commonly composed of a 3 DOF spherical type parallel mechanism and a 1 DOF needle insertion mechanism. This s

Recently, quite a few practical parallel mechanisms having spatial 3-DOF and 6-DOF have been introduced and implemented. However, not many useful practical applications using low-mobility parallel mechanisms having 4-DOF and 5-DOF have been developed

Two parallel mechanisms, a 1T2R (one translational motion and 2-DOF rotational motions) and a 1T3R (one translational motion and 3-DOF spherical motion), are proposed. The 1T2R mechanism consists of three sub chains. Specifically, the middle sub chai

A hybrid 6-DOF (degrees of freedom) mechanism which has closed-form forward and inverse position solutions is proposed. It consists of two different modules, a planar 3-DOF parallel module and a spatial 1T2R (1-DOF translational motion and 2-DOF rota

This paper proposes a new spatial 3-DOF parallel mechanism with a unique forward kinematic solution. Using the Scott mechanism as its sub-chain, the mechanism is foldable, which is useful for design of a compact-sized master device. The kinematics of
