Visual clues act as a substitute for haptic feedback in robotic surgery [PDF]
, 2018 Objective: The lack of haptic feedback (HF) in robotic surgery is one of the major concerns of novice surgeons to that field. The superior visual appearances acquired during robotic surgery may give clues that make HF less important. Methods: We surveyed

Autonomous Tissue Scanning under Free-Form Motion for Intraoperative Tissue Characterisation
, 2020 In Minimally Invasive Surgery (MIS), tissue scanning with imaging probes is required for subsurface visualisation to characterise the state of the tissue. However, scanning of large tissue surfaces in the presence of deformation is a challenging task for

The International Journal of Medical Robotics and Computer Assisted Surgery, 2006 AbstractBackgroundCardiac surgery, traditionally conducted via median sternotomy, has been recently forwarded by progressively advanced technology facilitating sternal‐sparing minimally invasive, access to the heart. Robotic systems, comprised of miniaturized surgical instruments mounted on long thin shafts with multiple degrees of range of motion ...

Advanced Functional Materials, EarlyView.The addition of calcium ions to silk fibroin enhances the hydrogel properties and, when combined with visible light crosslinking, enables compatibility with advanced light‐based fabrication techniques. Calcium ions extend the shelf‐life of silk and facilitate the fabrication of multizonal, multilayered constructs for advanced stimuli‐responsive ...

SPRK: A Low-Cost Stewart Platform For Motion Study In Surgical Robotics
, 2017 To simulate body organ motion due to breathing, heart beats, or peristaltic movements, we designed a low-cost, miniaturized SPRK (Stewart Platform Research Kit) to translate and rotate phantom tissue.

Advanced Functional Materials, EarlyView.This study demonstrates that the dual delivery of BMP‐2/‐7 coding cmRNAs for bone healing is demonstrated as feasible, safe, and highly osteogenic. Compared to single BMP‐2 or BMP‐7 cmRNAs, the combination enhances the production of both mineral and organic components of the extracellular matrix when delivered using a collagen‐HA scaffold, supporting ...

Are optical trocars free of complications?
Clinical Case Reports, 2019 Key Clinical Message Optical view trocars provide an acceptable level of safety for port entry during minimally invasive surgery. Nevertheless, this technique is not exempt from potential complications.

Advanced Functional Materials, EarlyView.A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.

Snapshot in surgery: How do you approach this 12‐year‐old girl?
Clinical Case Reports, 2018 Key Clinical Message This case open questions about the dimensional limit for a laparoscopic treatment of a giant bezoar. A minimally invasive option should be considered every time a gastric obstruction is suspected, particularly for psychiatric ...

Advanced Functional Materials, EarlyView.This study presents an injectable hydrogel that responds to Pseudomonas aeruginosa infection by releasing a dual‐phage cocktail on demand. The system degrades selectively in infected wounds, enhances phage localization and stability, and shows potent antibiofilm activity and biocompatibility in an ex vivo human skin model—offering a promising strategy ...
