Abstract: A flexible peristaltic robot with a built-in bidirectional gas pump for self-regulating gas flow. The robot includes a head-end airbag, an extension-retraction airbag, a tail-end airbag, a power module, a control module and a bidirectional gas pump. When there is harmful gas or less gas in the external environment, an additional airbag is provided in the flexible peristaltic robot to form a closed internal circulation of air flow. Otherwise, the robot directly exchanges gas with the external environment to form an open external circulation of air flow. The flexible peristaltic robot can either use multiple bidirectional air pumps or use a single bidirectional air pump and multiple electrically-controlled switches to control the expansion and contraction of the airbags to enable the robot to move forward.

Abstract: Hollow vector support multifunctional protection devices and systems for minimally invasive surgery are disclosed. In an embodiment, a hollow vector support multifunctional protection device includes a protective head, a pitching mechanism for the protective head, an inner cylinder, an axial movement mechanism for the inner cylinder, and a shell. The protective head includes a flap ring, a plurality of first rotating shafts, a plurality of flaps uniformly arranged on the flap ring through the first rotating shafts, and a torsion spring arranged on the first rotating shafts. The torsion spring is configured to provide a force for opening the plurality of flaps along the first rotating shafts, and the first rotating shafts are provided with limiting structures configured to limit a maximum opening degree of the flaps.
