Microsurgery

The Quantitative Assessment of Skills and Acquisition in Microsurgery project combines magnification with advanced microscopes and specialized precision tools to develop an objective evaluation tool for the assessment of microsurgical competence.

Motivation

Introduction

Microsurgery  is a type of surgery that uses powerful microscopes, specialized precision tools and various operating techniques. It is primarily used to anastomose small (1-2 mm) blood vessels i.e. to join two vessels together so that the blood can flow though and to coapt nerves.

Microvascular and microneural coaption are used for complex repair of human tissue, organ transplantations and revascularization of the brain.

Problem

Goal

Teaching and assessment of skill acquisition in microsurgery is tricky as there are not clear and objective standards. It relies on subjective opinions of senior faculty. However, optimizing the training of future microsurgeons is of great importance and includes objective assessment of skills,  learning curves, and value of various training models.

The goals of the proposed project is to add scientific knowledge on how hand position, force application and movements change during the surgeon’s trainings and to advance clinical teaching by developing an objective evaluation tool for the assessment of microsurgical competence.
