Endoscopes TRIZ Cases

A concentric single-tube stem keeps conductive paths isolated while reducing electrode distortion and supporting smooth endoscopic cutting.

Ultraviolet photopolymerization forms multiple higher-index cores in one transparent polymer, avoiding dissimilar-material interfaces that cause optical loss.

Outward-opening lumens route bending wires through a steerable member, supporting compact construction and fine distal manipulation.

An elastic body positions the rod relative to the electrode, simplifying incision, dissection, and local injection procedures.

A correction lens and optimized lens spacing keep principal rays parallel, preserving interference-fringe contrast in compact shape-measurement optics.

Cameras and illumination in a bite block guide oral-cavity positioning, enabling minimal dental X-ray volumes and lower radiation exposure.

A suction tube combines distributed apertures and a flexible uterine seal to simplify controlled postpartum hemorrhage management.

See how an integrally formed multilumen shaft uses a coupling tube, hub, adhesives, and surface features to connect a working channel to a handle port.

Axial, oblique, and loop electrodes enable selective RF ablation of nasal nerves while reducing collateral damage near the lacrimal gland.

Fluorescence from thermally generated substances combines with white-light imaging to reveal heat-invasion areas and estimate tissue depth.

A virtual control point offset beyond the endoscope tip moderates motion input, reducing abrupt field-of-view changes during robotic surgery.

A flexible support with integral protrusions curves inside an outer cylinder to place medical sheets smoothly while reducing breakage risk.

Integrated positioning, rotation, opening, closing, and deployment let physicians apply clips without support staff or communication errors.

Controlled filament tension helps retract and immobilize target tissue, improving precision during endoscopic dissection and biopsy.

Rotational use can loosen the screw-fastened liquid injection unit; locking projections hold port orientation for easier injection.

Controlled suction and expandable members collapse uterine and vaginal cavities to arrest postpartum hemorrhaging when conservative treatment is too slow.

An axial control wire and protection member keep snare and knife functions in one channel, reducing exchanges, contamination, and tissue trauma.

A continuous wire-mesh choke creates a fluid path that cools the ablation antenna, supporting uniform current and limiting tissue damage.

An AR head-mounted display overlays a 3D anatomical model and live endoscope marker so clinicians can track position and orientation together.

Expandable wire-loop electrodes conform to irregular body vessels, delivering pulsed fields that induce apoptosis with minimal thermal impact.

Two dichroic reflective surfaces merge violet, green, and red sources for flexible white-light and narrowband vascular endoscopy.

A ball-joint handle and independently actuated steering wires improve distal deflection while reducing hand coordination during endoscopic procedures.

Radial and axial magnetized components extend anchoring through body-cavity walls while keeping the surgical system compact for MIS.

A telescopic shaft and rotatable electrode accommodate varied tissue shapes, while an integrated channel conveys surgical smoke away.

An adaptive insulative layer stays intact for uterine polyps but delaminates on fibrous tissue to create a return path and prevent shorts.
