Method and system for simulating insertion of an elongate instrument into a subject

Abstract

A method for simulating insertion of an elongate instrument into a subject, the method comprising: receiving one of an actual angular position and an angle of rotation of a proximal segment of the elongate instrument, wherein at least the distal end of the elongate instrument end insertion into the medical device; determining the distal angular position of the distal end of the elongated instrument inserted into the medical device using the adjustment factor and the one of the actual angular position and the rotational angle of the proximal section of the elongated instrument generating a medical image of at least a portion of the subject, the medical image including at least a representation of a distal segment of the elongated instrument, the representation of the distal segment being generated from the distal angular position; and outputting the generated medical image.

Description

technical field [0001] The present invention relates to medical simulation systems and methods, and more particularly to systems and methods for simulating the insertion of an elongate instrument into a subject. Background technique [0002] Minimally invasive surgical procedures through the use of surgical instruments are increasingly used as an alternative to traditional surgical procedures. In fact, technological advances have provided miniaturized tools and implements that can be inserted into subjects by surgical instruments, such as catheters, to perform various tasks. These tools are often combined with video systems to provide an inside view of the process as it is being performed. [0003] Virtual simulation systems have been developed for training medical professionals to perform these types of procedures. These simulation systems are designed to provide interactive training by producing realistic simulated operating conditions through a combination of hardware c...

AI Technical Summary

Problems solved by technology

In fact, characteristics of the subject's body, such as the diameter of the artery into which the surgical instrument is inserted or the viscosity of the blood present therein, may lead to potential buckling and / or twisting of the surgical instrument, which may not have been accounted for during the simulation

Use of thin surgical instruments may further increase flexion and / or twisting
