Abstract
An anatomical model includes a first container, a second container disposed within the first container, and a third container disposed within the second container. The second container and the third container simulate components of kidney anatomy, and the model includes ballistics gel to improve echogenicity during an ultrasound-guided training procedure using the model.
Claims20
An anatomical model for nephrolithotomy training, comprising:
- a first container;
- a second container positioned within the first container, the second container at least partially filled with a mixture including ballistics gel and simulating a renal capsule;
- a third container disposed within the second container, the third container including one or more calcium carbonate stones and simulating a renal calyx, the third container further at least partially filled with a fluid;
- and
- one or more layers disposed around the third container, the one or more layers including ballistics gel,
- wherein implementation of the ballistics gel improves echogenicity during ultrasound-guided training procedures.
3 more elements
An anatomical model, comprising:
- a plurality of simulated anatomical components, including:
- a kidney for ultra-sounded guided procedure training, the kidney including:
- a renal capsule,
- a renal calyx disposed within the renal capsule, and
- a kidney stone disposed within the renal calyx;
- a collecting system including yellow fluid to mimic urine;
- and
- a tissue layer simulated by a predetermined amount of ballistics gel formed along the kidney.
5 more elements
A method, comprising:
- forming a model, by:
- providing a first container;
- disposing a second container within the first container, the second container at least partially filled with a mixture including ballistics gel and simulating a renal capsule;
- and
- disposing a third container within the second container, the third container including a fluid and a calcium carbonate stone immersed within the fluid,
- wherein implementation of the ballistics gel improves echogenicity during an ultrasound-guided training procedure.
