The present disclosure discloses a compliant mechanism () for application of radial resistance on a simulation endoscope (). The mechanism () comprises a support plate (), a ring member () rotatably mounted on the support plate () and a plurality of flexible beam assemblies () configured in an inner circumference of the ring member (). The plurality of flexible beam assemblies () comprises a first beam () connectable to the ring member () and a second beam () connectable to the support plate (), the circular motion of at least one of the support plate () and the ring member (), relative to each other, moves the plurality of flexible beam assemblies () radially inward and radially outward to selectively apply radial resistance on the simulation endoscope (). The complaint mechanism () of present disclosure are joint less mechanisms which are free from backlash and friction in joints.

Compliant mechanism for simulating endoscopy

A microelectromechanical (MEMS) switch includes a substrate, a force-activated latching mechanism, and a spring-loaded shuttle. The latching mechanism has a proximal end and a distal end. In an embodiment, the latching mechanism includes two flexible latch arms each fixed at or about a proximal end and having a free distal end, and a connector connecting the latch arms. The spring-loaded shuttle includes a shuttle portion including a portion configured for engaging portions of the latch arms. The shuttle portion further being configured to translate about the substrate. The latching mechanism and the shuttle may be configured to include an electrical contact layer such that when the latch arms are engaged with the shuttle portion, a closed electrical circuit can be formed.
