Minimally Invasive Surgery (MIS) evolved as an alternative to open surgical approaches,
and resulted in reduced surgical trauma and faster recovery. However, the confined …

Continuum robots can traverse anatomical pathways to intervene in regions deep inside the
human body. They are able to steer along 3D curves in confined spaces and dexterously …

A major advantage of surgical robots is that they can reduce the invasiveness of a procedure
by enabling the clinician to manipulate tools as they would in open surgery but through …

Concentric tube robots (CTRs) have drawn significant research attention over the years,
particularly due to their applications in minimally invasive surgery (MIS). Indeed, their small …

Manual navigation of a guidewire is the first step in endovascular interventions. However,
this procedure is time consuming with uncertain results due to tortuous vascular anatomy …

Concentric push–pull robots (CPPR) operate through the mechanical interactions of
concentrically nested, laser-cut tubes with offset stiffness centers. The distal tips of the tubes …

Concentric-tube robots for minimally invasive surgery pose a potential risk of tissue rupture
because of the structural instabilities caused by high value of bending-to-torsional-stiffness …

Concentric push–pull robots (CPPR) combine the simplicity, miniaturization potential, and
open lumen of concentric-tube robots with the kinematic advantages and stability of push …

Variable stiffness enables the safe and effective operation of the minimally invasive surgical
instruments. In this article, we propose a continuously variable stiffness mechanism of the …

A neurosurgical robot with 3-dimensional (3D) distal manipulation can increase instrument
workspace for reaching peripheral regions of intracranial lesions to achieve complete lesion …
