From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

Low-cost prototyping of nitinol wires/frames using polymeric cores and sacrificial fixtures with application in individualized frames anchoring through the atrial septum

Scientific Reports, 2023
Self-expanding frames for minimally invasive implants are typically made from nitinol wires and are heat treated to maintain the desired shapes. In the process of heat treatment, nitinol structures are placed in a high-temperature oven, while they are ...

Nitinol Compression Staples in Foot Orthopaedic Surgery: A Systematic Review

Foot & Ankle Orthopaedics
Background: Nitinol compression staples have been increasingly used in foot and ankle orthopaedic surgery because of simple implantation, reproducibility, and favorable biomechanical features. Compared with traditional implants (i.e., plates and screws),

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots

Advanced Robotics Research, EarlyView.
A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

The microstructure and mechanical properties of nitinol manufactured by LPBF: differences between Ni-rich and Ti-rich compositions

Virtual and Physical Prototyping
The utilisation of laser powder bed fusion (LPBF) for nitinol alloys has garnered significant interest, owing to its capability to achieve a 4D response through the shape memory (SME) and superelastic (SE) effects.
