These days, I’m trying to pay it forward. Two of my uncles took me hunting before I was old enough to go on my own. They took me on many trips that involved time in nature. Both my sets of grandparents were amazing. My parents took me camping as kid, and allowed me the freedom to roam about outdoors. So much of my love for the outdoors comes from these simple trips with people who cared about me. It was a memory we’d recall and laugh about for 30 years. On one early trip, my grandma bought a giant sack of candy bars. I’ll never forget the big breakfasts, and being allowed to order fried shrimp for dinner. My grandparents would explore the small towns along the way. It was the biggest adventure of my life at that point. We went to Yellow Lake in Wisconsin, near the town of Webster. I think I was 8 the first time I went north with my grandparents. They wanted to be far enough north to need a light jacket in the morning and evening while fishing. They’d descend on some small fishing lake, where they’d stay in a rental cabin. With the “Lady Dee,” the boat he named after her because her name was Dorlis but people called her Dee, in tow. One week in the spring, another in the fall. My grandpa spent 50 weeks a year preparing for the two weeks he and Grandma would go up north. And when you get there, you’re probably going fishing. But for folks from Chicagoland, like myself, going north usually means you’re heading to one of those three states. Look, I’m keenly aware north is relative to where one lives, and in some sense, everywhere is north of somewhere. Michigan, Wisconsin, and Minnesota are what I mean when I talk about going north. Once the temperature is above 80, all I can do is dream of going north. I enjoy nothing about the heat of summer. It feels like you’re in a small bathroom with a closed door after taking a hot shower. ![]() Stepping outside through the sliding glass door onto my deck in the early afternoon is an unpleasant experience this time of year. The support system also adds protection to the instrument from external contamination.Even at this time of year, flannel shirts are still worn outdoors up north. The length, outer diameter, and inner diameter that emerge from the fold pattern can be customized to accommodate various robot designs and flexible instrument geometries without increasing the part count. The origami-based portion of the device is fabricated from a single sheet of polyethylene terephthalate. The origami-based portion of the device is combined with two rigid mounts for interfacing with the medical robot. The proposed origami pattern is composed of two repeated patterns: a bistable pattern to create support points to mitigate flexible shaft buckling and a monostable pattern to enable axial extension and compression of the support system. Varying parameters of a triangulated cylindrical origami pattern were combined to create an effective highly-compressible anti-buckling system that maintains a constant inner diameter for supporting an instrument and a constant outer diameter throughout actuation. This paper presents the development of an origami-inspired support system (the OriGuide) that enables the insertion of flexible instruments using medical robots.
