Endoscopes TRIZ Cases
- Hydroformed Surgical Shaft Joint for Weld-Free Handheld Assembly
Hydroforming joins the tubular shaft to the handheld body without welding, cutting assembly steps while preserving stability and sterility.
- Segmented Electrode Geometry for Hand-Held Electrosurgery
Straight, mirror-symmetrical wire sections increase electrode cross-section while simplifying manufacture and inspection for minimally invasive electrosurgery.
- Endoscope Valve Stem Seals for Leakage-Tolerant Clearance
Elastomeric seals and recessed stem sections maintain endoscope valve sealing with larger clearances, reducing leakage and precision cost.
- Hydroformed Surgical Handpiece Shaft Joint Without Welding
Hydroforming joins a surgical handpiece shaft to the body without welding, cutting assembly steps while improving joint strength and sterility.
- Computer-Vision Surgical Tool Control for In-View Safety Gating
Real-time computer vision detects tools and anatomy, enabling surgical functions only when instruments remain in view.
- Teleoperation Frame Alignment Without Full Position Tracking
Orientation-based registration aligns master controls, displays, and end effectors without full position tracking, improving teleoperation control.
- Nitinol Component Coupling Through Shape-Recovery Interference Fit
A stretched nitinol section is inserted into a receiver, then recovers its shape to lock dissimilar medical components without fillers or heat.
- Endoscope Holder with Gas Spring Arm for Stable Repositioning
A gas spring arm, rail slider, and clamp keep the endoscope stable yet easy to reposition, reducing manual effort during surgery.
- Laser-Welded Catheter Tip Guide Rings for Precise Bending
Laser welding fixes catheter tip guide rings without adhesive spread, preserving lumen integrity, spacing, flexibility, and durability.
- Tubular Weld Structure for Strong Endoscope Joint Fixation
Circumferential welds placed outside the holder projection region strengthen endoscope joint fixation while limiting ring diameter and heat damage.
- Manual Release Coupling for Surgical Drive Train Retraction
A sliding coupling and ratchet let surgeons manually retract instruments during power loss while protecting the drive train from damage.
- Thin-Walled Spiral Endoscope Tube With Localized Wall Thickening
Localized wall thickening, an internal flow channel, and an end ring help fully mold a single-piece spiral endoscope tube without voids.
- Computer-Vision Surgical Tool Control for Injury Prevention
Computer vision detects tools and anatomy in live surgery video, enabling functions only in view to reduce accidental patient injury.
- Integrated Glass Micro-Optics for Alignment-Free Fiber Coupling
Ultrafast laser writing and chemical etching form lenses and fiber channels in one glass substrate, avoiding manual micro-alignment.
- Surgical Handpiece Shaft Assembly Using Internal High-Pressure Forming
Internal high-pressure forming joins a tubular shaft to a surgical handpiece without welding, cutting assembly effort while preserving stability and sterility.
- Surgical Equipment Holder With Single-Lever Arm Locking
A single lever locks both arms and the end effector at once, enabling one-handed surgical accessory positioning and fine adjustment.
