Endoscopes TRIZ Cases

Multiple hemoclips deploy through an endoscope without manual reloading, reducing procedure time and cost per deployment.

Radial tool extensions fragment blood clots and debris while separate catheter suction clears the endoscopic field without repeated reinsertion.

A U-shaped steering wire spreads drag forces through friction, reducing stress concentration in an endoscope’s deflecting tip.

Segmented bending portions with joint rings and wires improve kink-resistance, torque transmission, and pushability during endoscopic procedures.

Existing trainers often focus on lesion observation; four-degree-of-freedom positioning moves organ targets for realistic endoscopic procedure practice.

Fixed sphincterotomes limit angle and deflection; a movable wire in a shaft lumen supports controlled tissue cutting.

A cylindrical heater and conductive filler speed shape memory alloy hardening while a tube prevents filler intrusion.

A telescopic rod and grooved cap let a sheath adapter slide and rotate for precise surgical instrument alignment, simplifying assembly.

A distal rotor modulates channel pressure, fragments foreign bodies, and clears suction obstructions during emergency gastrointestinal endoscopy.

An integrated PCB stores cable authentication and usage data while imaging lines bypass the bus for reliable signal transfer.

Angled end faces let shaft sections rotate for continuous bending while the pivot joint holds position under surgical load.

Multiple pull-wire segments and a spiral-lumen nitinol backbone help preserve the neutral axis during robotic instrument bending.

A voltage-generation circuit biases the imaging pixel well without an external negative-voltage circuit, supporting compact endoscope systems.

Disposable coolant cartridges and a removable endoscope attachment reduce reliance on bulky pressurized tanks for surgical flow delivery.

Multiple probe-mounted light sources detect and treat infection in body cavities while active cooling manages heat for prolonged placement.

Coordinated motor control moves an endoscope, stabilizer, and treatment tool to improve cervical engagement, uterine tissue resection, and fluid management.

A vibrating sheath reduces wire friction during large-angle bending, while a detachable disposable module limits infection risk and preserves force transfer.

Steering wires and a movable handle give an endoscopic shaft independent deflection for precise tissue manipulation.

Nested first and second motors use mounting space efficiently, making capsule endoscope control more compact and easier to move.

A flexible hood-mounted LED structure delivers low-level light to the duodenum while limiting mucosal and organ damage.

Separate clock trees coordinate pixel-array drive, horizontal transfer, and AD conversion while reducing clock buffers, circuit scale, and power use.

The nested inner and outer sleeves let a robot arm provide controlled mucosal traction, clarifying ESD dissection fields and reducing operation difficulty.
