Comparison of Manual Versus Robot‐Assisted Piston Prosthesis Placement and Crimping in a 3D‐Printed Temporal Bone Model

Laryngoscope Investigative Otolaryngology, Volume 11, Issue 4, August 2026.
ABSTRACT Objectives To reduce operator‐dependent variability and improve surgical precision, robot‐assisted piston prosthesis placement and crimping during otosclerosis surgery may represent a promising approach. However, dedicated microsurgical forceps for this application are not yet available in clinical practice.

Nitinol 3D Printed by Micro Gas Metal Arc-Based Direct Energy Deposition

Journal of Manufacturing and Materials Processing
Additive manufacturing of NiTi shape memory alloys is challenging due to their sensitivity to composition and thermal history. The gap between high-resolution powder-based AM and high-productivity wire-based processes for NiTi remains a challenge.

A Hybrid Compliant–Tendon Laparoscopic Instrument for Distal Articulation and Grasping: Design and Experimental Validation

The International Journal of Medical Robotics and Computer Assisted Surgery, Volume 22, Issue 4, August 2026.
ABSTRACT Background Conventional laparoscopic instruments provide limited dexterity in confined anatomical environments, whereas existing articulated designs rely on complex rigid joints or motorised actuation, increasing mechanical complexity and limiting miniaturisation.

Ejaculatory Dysfunction and Minimally Invasive Surgical Treatments (MIST) for Male Lower Urinary Tract Symptoms Secondary to Benign Prostatic Enlargement

Trends in Urology &Men's Health, Volume 17, Issue 4, August 2026.
ABSTRACT While transurethral resection of the prostate (TURP) is considered the standard surgical treatment in symptomatic benign prostatic enlargement (BPE) secondary to benign prostatic hyperplasia (BPH), it is not without surgical morbidities and has adverse impact on various sexual function domains such as ejaculatory dysfunction (EjD) and erectile

Influence of Heat Treatment of Nitinol Wire on the Properties of Nitinol/Hybrid Layer for Ibuprofen Release

Molecules
The efficiency of drug delivery from coatings of metallic implants is one of the key factors. The influence of chemical and thermal treatments of nitinol wire on the corrosion properties, deposition of hydroxyapatite(HA)/poly ε-caprolactone-polyethylene glycol (PEG-b-PCL), and the amount of ibuprofen released from that bilayer were studied.

Designing and simulating a nitinol-based micro ejector

Ingeniería e Investigación, 2012
This paper describes pico-droplet ejector design and simulation. The actuation system was based on two interconnected nitinol membranes’ shape memory effect. Ejected volume was 12pL and it operated at 30°C to 64°C. Ejecting excitation voltage was 12V and
