Surgical Needles TRIZ Cases
- Stylet Guide-Assisted Biopsy Needle System
A biopsy system uses a thin guide stylet to establish a safe path, reducing bleeding and pneumothorax risk during needle repositioning.
- Thread-like Cutting Element for Kerf-less Ligament Transection
A thread-like cutting element routed around a ligament achieves precise transection through minimally invasive punctures.
- Asymmetric Surgical Needle for Dense Tissue Penetration
A surgical needle uses an asymmetric cross section with a rounded inner surface and outer cutting edge to penetrate biological tissue.
