Simulated Knot Tying
Applications such as suturing in medical simulations require the modeling of knot tying in physically realistic rope. The paper describes the design and implementation of such a system. Our model uses a spline of linear springs, adaptive subdivision and a dynamics simulation. Collisions are discrete event simulated and follow the impulse model. Although some care must be taken to maintain stabl...
متن کاملKnot-tying with four-piece fixtures
We present a class of fixtures that can be disassembled into four pieces to extract the loosely-tied knot. We prove that a fixture can be designed for any particular knot such that the knot can be extracted using only simple pure translations of the four fixture sections. We explore some of the issues raised by our experimental work with these fixtures, which show that simple knots can be tied ...
متن کاملIntracorporeal knot-tying for the thoracoscopic surgeon: a novel and simplified technique.
Thoracoscopic surgery has usually been limited by 2-dimensional vision and the limited space between ribs--problems that have been only partially overcome by the use of robotics. One of the technical challenges of any minimally invasive surgical approach is tying an intracorporeal knot. For the thoracoscopic surgeon, we describe an easier technique of knot-tying that involves using a right-angl...
متن کاملA simple technique for knot tying in single incision laparoscopic surgery (SILS)
Minimal access surgery has been generally accepted as a method of operating through a very small incision or no incision at all. Today, all abdominal and thoracic surgeries can be performed with laparoscopy. Intracorporeal knot tying is an advanced skill that involves a difficult process with a long learning curve. In particular, when the angle between the working instruments is narrow and the ...
متن کاملTowards a Better Laparoscopic Knot: Using Knot Quality Scores to Evaluate Three Laparoscopic Knot-Tying Techniques
OBJECTIVE In the past, knot-tying techniques have been evaluated and compared, but there has been a scarcity of objective scoring systems in these comparison studies. Using an objective scoring system, we aimed to compare 3 types of knots: intracorporeal flat-square knots, intracorporeal slip-square knots, and extracorporeal square-knots for their Knot Quality Scores (KQS) and their rates of sl...
