Abstract

Surgical training apparatus, methods and systems which allow surgical trainees to practice surgical skills on anatomical models in a realistic manner with an augmented reality headset and delivery of targeted surgical coursework curriculum correlated to the actions of the trainee as sensed by sensors in or adjacent the model to help the trainee develop proper surgical technique and decision making.

Claims

1. A surgical training system, comprising:

a) a model of an anatomical part of a human or animal;

b) one or more sensors attached to said model, said one or more sensors operable to emit a signal in response to receiving an activation input;

c) an augmented reality headset having one or more electronic and/or optical input and output channels adapted to receive electronic signals from said one or more sensors;

d) a computer processor operable to receive signals from said augmented reality headset and/or said one or more sensors;

e) a computer database having surgical training curriculum having one or more individual surgical subject matter components stored therein; and

f) a software program running on said computer processor and connected to said database, said software program operable to correlate said one or more sensor signals to said one or more individual surgical subject matter components, said software program being further operable to provide as a first output the individual surgical subject matter component which is correlated to a received signal emitted in response to receiving the activation input in step (b).

2. The surgical training system of claim 1, wherein said one or more sensors include two or more sensors embedded within said model and exposed upon cutting an opening into said model, said one or more sensors operable to emit a signal in response to contact with a fluid flowing within said opening.

3. The surgical training system of claim 2, wherein two or more sensors are positioned at different depths within said model and are operable to sense an increasing fluid flow by activation of said two or more sensors in sequence.

4. The surgical training system of claim 3 wherein said software program is operable to correlate each of said two or more sensors with a volumetric quantity of fluid wherein each of said two or more sensors correlates to a different volumetric quantity of fluid.

5. The surgical training system of claim 4 wherein said software program is operable to provide a second output perceptible to the trainee in response to said volumetric quantity of fluid reaching or exceeding a predetermined threshold.

6. The surgical training system of claim 5 wherein said second output is one or more of an audible alarm or text message.

7. The surgical training system of claim 6 wherein said second output is a text visible in said augmented reality headset.
