Published: July 2013

A handheld Smart Micromanipulation Aided Robotic-surgery Tool (SMART) micro-forceps guided by a fiber-optic common-path optical coherence tomography (CP-OCT) sensor is presented. A fiber-optic CP-OCT distance and motion sensor is integrated into the shaft of a micro-forceps. The tool tip position is manipulated longitudinally through a closed loop control using a piezoelectric motor. This novel forceps design could significantly enhance safety, efficiency and surgical outcomes. The basic grasping and peeling functions of the micro-forceps are evaluated in dry phantoms and in a biological tissue model. As compared to freehand use, targeted grasping and peeling performance assisted by active tremor compensation, significantly improves micro-forceps user performance.

Purpose: Internal limiting membrane (ILM) is usually peeled simultaneously with epiretinal membrane (ERM), however, in eyes with glaucoma and ERM, ILM is preserved in order to prevent nerve fiber damage. The aim of this study was to evaluate if a new approach for ERM is effective to keep ILM during surgery.

Study Design: Retrospective consecutive case series.

Assessment of the Risk of Crack Formation at a Hybrid Bonding Interface Using Numerical Analysis.

Micromachines (Basel)

October 2024

Intelligent Semiconductor Engineering Department, Seoul National University of Science and Technology, Seoul 01811, Republic of Korea.

Hybrid bonding technology has recently emerged as a promising solution for advanced semiconductor packaging technologies. However, several reliability issues still pose challenges for commercialization. In this study, we investigated the possibility of crack formation caused by chemical mechanical polishing (CMP) defects and the misalignment of the hybrid bonding structure.

Article Synopsis
  • High peel strength is essential for polyacrylate latex pressure-sensitive adhesives (PSAs) to ensure durability and expand their use in industries like packaging, electronics, and medical applications.
  • Current polyacrylate latex PSAs lack sufficient peel strength, limiting their market potential and applications in advanced fields.
  • This study introduces a novel high-peel-strength PSA by modifying traditional polyacrylate latex with 3,4-dihydroxybenzaldehyde (DHBA), enhancing adhesive properties significantly, with peak performance at a DHBA content of 4.0%, resulting in a notable increase in peel strength and water resistance.

Comparison of Surgical Times Between Manual and Robot-Assisted Epiretinal Membrane Peeling.

Transl Vis Sci Technol

August 2024

Department of Ophthalmology, Stadtspital Zürich, Zurich, Switzerland.

Purpose: Epiretinal membranes (ERM) pose a common challenge in vitreoretinal pathology, often causing vision impairment in older adults. The Preceyes Surgical System (PSS) supports the surgical removal of ERM through robot-assisted membrane peeling (RA-MP). This study compares surgical times and iatrogenic hemorrhages between manual membrane peeling (MMP) and RA-MP using PSS.

Article Synopsis
  • The study introduces a new visualization method for peeling epiretinal membranes (ERM) using the Alcon Ngenuity 3D System's picture-in-picture feature connected to a smartphone.
  • Conducted on 20 patients, researchers used optical coherence tomography angiography to create detailed en-face images, enabling precise peeling of the ERM without the use of dye stains.
  • Results showed a 100% success rate in the initiation of peeling, with significant improvements in central macular thickness one month post-surgery, highlighting the technique's efficiency and ease of use.
