Affordable Mobile-based Simulator for Robotic Surgery [PDF]
arXiv, 2018 Robotic surgery and novel surgical instrumentation present great potentials towards safer, more accurate and consistent minimally invasive surgery. However, their adoption is dependent to the access to training facilities and extensive surgical training. Robotic instruments require different dexterity skills compared to open or laparoscopic.

Advanced Healthcare Materials, EarlyView.The PVA‐GA hydrogel is formed through hydrogen bonding between PVA hydroxyl groups and GA galloyl units, enabling sustainable GA release and its extended biological activity. The hydrogel scavenges ROS to reduce oxidative stress, preventing mitochondrial damage from excessive ROS, mitigating hADSC senescence, and preserving VEGF secretion, offering a ...

Advanced Healthcare Materials, EarlyView.A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...

Robotic surgery in pediatric urology
Asian Journal of Urology, 2017 While robotic surgery has shown clear utility and advantages in the adult population, its role in pediatrics remains controversial. Pediatric-sized robotic instruments and equipment are not readily available yet, so certain modifications can be made in ...

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.DexaPatch, an implantable, low‐swelling amphiphilic hydrogel system containing dexamethasone‐PLGA microparticles, is developed and characterized for sustained local steroid release to reduce postoperative inflammation in tight surgical spaces. DexaPatch significantly reduces postoperative edema and fibrosis in a rabbit model of anterior spinal surgery,

Robotic Applications in Cardiac Surgery [PDF]
International Journal of Advanced Robotic Systems, Volume 1,
Number 2, June 2004, pp.87-92, 2004 Traditionally, cardiac surgery has been performed through a median sternotomy, which allows the surgeon generous access to the heart and surrounding great vessels. As a paradigm shift in the size and location of incisions occurs in cardiac surgery, new methods have been developed to allow the surgeon the same amount of dexterity and accessibility to ...

Advanced Healthcare Materials, EarlyView.The covalent binding of dexamethasone to the surface of polyimide represents the electrically inert part of implantable intraneural devices. This ensures a sustained release of the drug for 9 weeks. In vitro and in vivo tests confirm the reduction of the foreign body reactions and the improved biocompatibility of dexamethasone functionalized polyimide.

Automatic Tip Detection of Surgical Instruments in Biportal Endoscopic Spine Surgery [PDF]
arXiv, 2019 Some endoscopic surgeries require a surgeon to hold the endoscope with one hand and the surgical instruments with the other hand to perform the actual surgery with correct vision. Recent technical advances in deep learning as well as in robotics can introduce robotics to these endoscopic surgeries.
