Ultrasound-Guided Invasive Procedure Trainer

Designed for use in maternal-fetal medicine, this ultrasound simulation device features adjustable components that make it suitable for training at various levels of expertise in all fields in which ultrasound-guided invasive procedures are employed.

Problem

Ultrasound-guided invasive procedures (such as amniocentesis) are delicate tasks that require hand-eye coordination, manual dexterity and other abilities. Clinicians need to acquire, develop and practice these skills in a risk-free environment before performing such procedures in a clinical setting. But the devices currently available for training in ultrasound-guided invasive procedures simulate specific anatomic structures with fixed target constructs, which severely limits their instructional utility.

Solution

A Wake Forest Baptist Medical Center physician who instructs postgraduate fellows in maternal-fetal medicine invented a training device with a number of interchangeable and moveable targets. This simulator can be configured to be more or less challenging and to mimic various patient situations for different procedures in maternal-fetal medicine and other fields.

The ultrasound simulation device was received favorably by clinicians at the 2015 meeting of the Society of Maternal-Fetal Medicine, Duke University Hospital and UNC Hospitals. It is currently being used to train postgraduate fellows at the Wake Forest Baptist Medical Center.
