However, the body structure is too simple, resulting in the utilization rate of oxygen being usually low. In this work, we reported a deformable rigid bronchoscope (named Oribron) by adding a Waterbomb origami structure to the body. The Waterbomb's backbone is made of films, and the pneumatic actuators are placed inside it to achieve rapid deformation at low pressure. Experiments showed that Waterbomb has a unique deformation mechanism, which can transform from a small-diameter configuration (#1) to a large-diameter configuration (#2), showing excellent radial support capability. When Oribron entered or left the trachea, the Waterbomb remained inMicromachinesOribron: An Origami-Inspired Deformable Rigid Bronchoscope for Radial Support.PMC10144517SYC2022044619032692022AH030077KJ2021A0249Yang KZhang YZhu LCheng LYang RSu JNiu FDuan YfalseOribron: An Origami-Inspired Deformable Rigid Bronchoscope for Radial Support.The structure of a traditional rigid bronchoscope includes proximal, distal, and body, representing an important means to treat hypoxic diseases.
