Surgical Scissors TRIZ Cases

Dynamic coupling prevents accidental cutting by controlling activation based on jaw position.

A surgical instrument uses a selecting member to switch jaws between grasping and cutting modes.

A medical instrument bearing uses a compressed biasing element to exert force between pivot areas, compensating for wear and maintaining motion force.

A surgical instrument features a pivotable and yawable jaw mechanism that transitions from grasping to cutting positions.

A surgical instrument crank and collar mechanism provides multiple degrees of freedom for precise tissue manipulation.

Cam-slot and cam-pin operation enables symmetrical blade opening while allowing rotation for insertion through narrow endoscope entry ports.

A surgical cutting instrument uses convex ruled surfaces to guide tendon sliding for precise robotic micro-surgery.

A surgical instrument handle incorporates a thenar eminence contacting surface to enable intuitive palming control during procedures.

Adapter converts rotary handle motion into axial translation, minimizing unwanted over-articulation during stapling.

Longitudinal groove actuation eliminates proximal blade extensions that deform insulation tubing and interfere with tissue during trocar withdrawal.

A surgical dissector instrument with pivotably connected arms features opposable contact surfaces that conduct electricity for tissue cauterization.

Segmented yoke components enable independent jaw rotation and articulation, resolving the trade-off between device complexity and operational versatility.

A medical device tip locking mechanism uses a spring-loaded latch to secure the tip housing.

A laparoscopic instrument uses a slidable sleeve to detach disposable end effectors, reducing injury risk and component complexity.
