Thirty Degree Scope View

  • Having the capability to simulate an angled scope is a novel component of the laparoscopic box trainer. Learners can practice using this view in any module.
  • For a 30-degree (30◦) view, stretch the free rubber band hanging from the top of Part E around the smartphone in the vertical direction
  • Lower the smartphone into the rectangular cutout in Part E
