A bone screw with a segmented insertion post breaks at a predetermined point to prevent tissue damage and enable standard tool removal.
- Robotic Visualization System Collision Avoidance via 3D Path Planning
A robotic visualization system adjusts its pose and imaging configuration using a 3-D model to capture target fields of view.
- Intracranial Catheter Placement Guided by Intra-luminal Ultrasound
A drilling device cannulation guides a thin ultrasound probe for real-time anatomical visualization during catheter placement.
- Medical Instrument Disinfecting System with Automated Traceability
A disinfecting chamber acquires instrument identification data and cycle characterization data to generate traceability records.
- Circular Stapler Anvil Spline Alignment Offset
Offset spline apexes guide sequential engagement, preventing binding and ensuring accurate staple formation.
- Instrumented Catheter with Embedded Strain Gauge for Shape Sensing
An instrumented catheter uses embedded strain gauges to detect shape and force, preserving lumen space by replacing bulky mechanical sensors.
- Flash Lamp Handpiece Energy Adaptation for Depilation
A flash lamp handpiece adapts energy delivery based on stored stress data to maintain optimal performance.
- Wearable Oscillation Harness With Strap Tension Sensing
A wearable oscillation harness integrates force sensors into securing straps to monitor device application and ensure correct treatment delivery.
- Tricuspid Valve Repair Using Nested Shape Memory Discs
Segmented concave and convex discs grasp three leaflets simultaneously, reducing tension while improving coaptation quality.
- Disposable Absorbent Package Opening Tab Design
A segmented opening tab extends beyond the vacuum seal to resolve the contradiction between compact package size and ease of operation.
- Rotational Hinge Assembly for Knee Brace Osteoarthritis Treatment
A rotational hinge assembly uses adjustment screws to apply dynamic treatment forces to the knee joint.
- Surgical Knife Sharpening Without Disassembly
A jack holds spaced-apart jaws to extend a surgical knife, reducing reprocessing time by avoiding full disassembly.
- Cleaning Cap With Movable Piston For Male Luer Disinfection
A cleaning cap housing a movable piston dispenses solution onto male luer protrusions upon insertion.
- Surgical Docking Device Two-Part Adapter Pivot Registration
Segmented docking adapters register pivot points before connection, preventing tissue damage during instrument clamping.
- Rehabilitation Support System Using Facial Expression Feedback
A rehabilitation support system acquires trainee motivation data via facial expressions to guide real-time physical assistance.
- Medical Instrument Introducer for Multi-Tool Delivery
A medical instrument introducer holds multiple tools in a nested assembly for simultaneous insertion through a single channel.
- Endoscopic Closure Device With Retention Teeth
Retention teeth on a stationary jaw maintain tissue engagement during deployment, resolving incomplete closure of large mucosal defects.
- Electrosurgical Generator Camera Instrument Detection
An electrosurgical generator uses a camera and image processor to identify connected instruments, eliminating proprietary interface complexity.
