Load sensing surgical instruments.

Intra-operative Ischemia Sensing Surgical Instruments

Surgical techniques rely heavily on adequate visualization of target anatomy. Particularly in laparoscopic and robotic laparoscopic surgery, the operative anatomy and the general view of the operative field is removed from the surgeon’s direct vision. Manipulation of peripheral anatomy (i.e. retraction) may lead to ischemia, infarction, and mechanical disruption. The primary goal of our researc...

A soft pop-up proprioceptive actuator for minimally invasive surgery

INTRODUCTION Surgical robots and miniaturized smart instruments have been developed to overcome limitations of current tools and further reduce invasiveness of surgical procedures [1][2]. This miniaturization effort, as well as the development of more flexible instruments that can navigate the body following complex anatomical paths toward the surgical target, often leads to the loss of sensory...

Group 5 Project Proposal Prototype of a Micro-Surgical Tool Tracker

Computer and robot assisted eye surgery has great potential to address common problems encountered in many eye surgery tasks including poor visualization, lack of force sensing, hand tremor, and accessibility. Positional feedback of the instruments relative to the eye can be used to prevent undesirable collisions, improve remote center of motion interaction, and possibly automate tasks like ins...

Strain and Damage Sensing Property of Self-compacting Concrete Reinforced with Carbon Fibers

Present paper investigated the strain and damage sensing property on concrete cubes embedded with carbon fibers. Concrete cubes of dimension 150 mm have been casted with different concentration of carbon fibers to study the strain and damage sensing property under cyclic loading that can be further used for health monitoring as non-destructive testing (NDT) approach. All the specimens were test...
