Incision Instruments TRIZ Cases

A shape-memory magnetic coil creates single-puncture anastomosis while an expandable stent provides immediate drainage and helps reduce leaks.

An elevator, retainer, and blade assembly lifts and cuts dura mater quickly while shielding underlying brain tissue for single-surgeon use.

An offset-lumen guide and guarded working channel enable precise lamina decompression while reducing neural injury risk and preserving spinal stability.

A universal handle with keyed, attachable surgical bits and built-in light reduces tool changes, tissue injury risk, and handle count.

A single-piece sterile plastic guide protects ligament and fascia during endoscopic release while reducing detachment and re-sterilization risks.

A mesh-backed zipper closure improves wound-face registration, reduces scarring risk, and allows selective reopening for incision access.

A guarded blade and introducer shaft enable minimally invasive thumb tendon release while shielding nearby nerves and blood vessels.

Inward septal cutting from a preset intersection improves multi-cuspid shunt symmetry, valve performance, and atrial pressure regulation.

A wood-fiber plastic waste container uses snap locks and a radial press seal to keep medical sharps and liquid waste secure and recyclable.

A cut-resistant guard inside a containment bag enables closed morcellation through small openings while preventing malignant tissue spread.
