Abstract
A trainer for cardiac surgery and other similar procedures includes an organ model such as a cardiac model, an animation network adapted to impart to the model a motion similar to the corresponding natural organ and a control device used to control the operation of the animation network. The cardiac model is made of two sections, an inner cast simulating the myocardium and an external shell simulating the pericardium. The model is made by forming an inner cast, dressing the cast and then forming the shell around the cast. The model is preferably made of silicon rubber.
Claims17
A cardiac trainer comprising:
- a heart model made of a relatively soft material and having a size and shape of a heart;
- an animation network disposed in said heart model and arranged to twist said heart model about two perpendicular axes at a predetermined rate resulting in a three dimensional twisting motion that simulates the motion of the heart and
- a control device connected to said animation network to selectively activate said animation network.
A teaching device comprising:
- a heart model made of a relatively soft material and being shaped to resemble a heart;
- an animation network disposed in said heart model and arranged to twist of said heart model about two perpendicular axes at a predetermined rate resulting in a three dimensional twisting motion that simulates the motion of the heart said animation network including a first tube;
- and
- a control device connected to said animation network to selectively activate said animation network by selectively pressurizing said tube to change the length of said first tube.
A teaching device comprising:
- a heart model made of a relatively soft material and being shaped to resemble a heart;
- an animation network disposed in said heart model and arranged to move said heart model in a manner so as to twist of said heart model about two perpendicular axes at a predetermined rate resulting in a twisting motion that simulates the motion of the organ, said animation network including a first tube formed of a flexible pipe having two ends and a mesh attached to the ends of the pipe, wherein said pipe and mesh expand radially to shorten said pipe longitudinally when said first tube is pressurized;
- and
- a control device connected to said animation network to selectively activate said animation network by selectively pressurizing said tube to change the length of said first tube.
An anatomical trainer for a biological organ having muscle-like motion for use as a training device in simulated medical procedures comprising:
- an organ model part having anatomical details of a biological organ;
- an animation network coupled to said organ model;
- and
- a control device connected to said animation network to operate said animation network in a manner that induces a twist of said organ model about two perpendicular axes at a predetermined rate resulting in a three-dimensional twisting motion that simulates the motion of the biological organ.
