Surgical Navigation Systems TRIZ Cases

Orientation-only tracking overlays a virtual surgical instrument on fluoroscopic images, cutting registration time and screw placement errors.

Real-time graphical overlays track treated and untreated target sites during surgery, reducing memory load when anatomy moves or blocks view.

Mixed reality guidance uses patterned tracking guides to align drills and impactors accurately, reducing angle errors and surgical complications.

Tracked bone-surface comparison helps guide implant augment placement in hip revision surgery, reducing reliance on surgeon experience.

Magnetic field sensing locates a paired endoscope through tissue walls, enabling precise lumen alignment and connection when ultrasound reach is limited.

A 6-DOF joystick and nearby actuation button give surgeons precise sterile control of robot arms and end effectors without voice errors.

Additional tissue-type validation filters covered or erroneous surface points, improving geometry capture accuracy in medical navigation.

A passive resonant tag lets a reader track nasogastric tube position in real time without X-ray exposure or complex active sensors.

Projected light patterns, 3D cameras, and INS tool tracking maintain vertebra navigation accuracy despite occlusion and patient movement.

A hollow flexible core with an inner magnetic layer and outer coil resists deflection breakage while preserving catheter tracking accuracy.

A dual-rigid-body marker layout reduces lever-arm and rotational tracking errors while preserving sterile access around the intervention site.
