Active colonoscopy training model and method of using the same

A colonoscopy training model comprising:

• an abdominal model comprising an outer body having a hollow interior portion therein;
• a colorectal tube operably coupled to the abdominal model within the interior portion of the outer body, the colorectal tube configured to replicate a human colon;
• and
• a pressure transducer operably coupled to the colorectal tube,
• wherein the colorectal tube is configured to receive a colonoscope and the pressure transducer is configured to measure an interstitial pressure within the colorectal tube when the colonoscope is positioned therein for determining a position of the colonoscope.

A colonoscopy training model comprising:

• an abdominal model comprising an outer body having a hollow interior portion therein;
• a colorectal tube positioned within the interior portion of the outer body, the colorectal tube configured to replicate a human colon;
• a plurality of fixtures operatively connected between the colorectal tube and the abdominal model, the plurality of fixtures configured to secure the colorectal tube within the hollow interior portion;
• and
• a plurality of load cells positioned along the colorectal tube respectively at an interface between the plurality of fixtures and the colorectal tube,
• wherein the colorectal tube is configured to receive a colonoscope and the plurality of load cells are configured to detect a tension applied to the colorectal tube by the colonoscope when the colonoscope is positioned therein for determining a position of the colonoscope.

A method of colonoscopy training using a colonoscopy training model comprising an abdominal model having an outer body, an anus unit positioned at one end of the outer body, a colorectal tube fixedly coupled to the anus unit and positioned within the outer body, a pressure transducer operably coupled to the colorectal tube, and a computer for receiving and displaying a pressure transducer indication, the method comprising:

• directing a colonoscope through the anus unit of the outer body;
• advancing the colonoscope through the colorectal tube;
• measuring an interstitial pressure within the colorectal tube with the pressure transducer;
• and
• monitoring the interstitial pressure.

A method of colonoscopy training using a colonoscopy training model comprising an abdominal model having an outer body, an anus unit positioned at one end of the outer body, a colorectal tube fixedly coupled to the anus unit and positioned within the outer body, a plurality of fixtures operatively connected between the colorectal tube and the abdominal model, a plurality of load cells positioned along the colorectal tube respectively at an interface between the plurality of fixtures and the colorectal tube, and a computer for receiving and displaying load cell indications, the method comprising

• directing a colonoscope through the anus unit of the outer body;
• advancing the colonoscope through the colorectal tube;
• measuring a tension by at least one of the plurality of load cells;
• determining a force applied by the colonoscope during a training session by the measured tension;
• and
• monitoring the force applied by the colonoscope.
