Incision Instruments TRIZ Cases
- Electrosurgical Blade With Graduated Flexibility for Curved-Jaw Cutting
A graduated-flexibility blade and low-friction coating ease movement between curved jaws for smoother tissue cutting and coagulation.
- Surgical Image Guidance for Real-Time Soft Tissue Deformation Tracking
Optical surface data and ultrasound subsurface data update a 3D model in real time, improving surgical guidance.
- Dual-Platform Ophthalmic Knife for Complete Trabecular Meshwork Removal
A dual-platform ophthalmic knife severs trabecular meshwork tissue using a segmented blade design.
- Slotted Transparent Cannula for Endoscopic Pulley Release
A slotted transparent cannula integrates a sliding blade assembly and endoscope window for single-handed minimally invasive surgery.
- Laser Scalpel Acute Angle Coupling Surface
Acute angle coupling surface refracts laser light through transmissive scalpel body to cutting edge.
- Surgical Instrument Guide Tissue Separation and Depth Control
A surgical instrument guide lifts and directs tissue to facilitate precise cutting during procedures.
- Surgical Instrument Integrated Local Anesthetic Delivery
Integrating a valve mechanism into the handle enables one-handed local anesthetic delivery during surgery, resolving the need for two hands.
- Puncture Awl with Stop Surface for Minimal Skin Access
A puncture awl creates a 2 to 3 mm skin opening for trocar insertion.
- Multi-blade Dermatome Assembly with Throughgoing Apertures
Segmenting blades into multiple units with throughgoing apertures resolves drive pin interference, enabling simultaneous harvesting of laminated skin grafts.
- Centrifugal Pump Fluid Cooling for Microwave Antenna Temperature Control
A centrifugal pump circulates fluid through a thermally conductive tube to cool a microwave antenna during tissue ablation.
- Intravascular Dissection Device for Controlled Valve Leaflet Formation
A catheter-based dissection arm deploys within a vessel wall to separate tissue and form precise valve leaflets.
- Surgical Instrument Bearing Pin With Passage Opening
A surgical instrument bearing pin features a passage opening that allows easy insertion and withdrawal of the separating device.
- Biosafety Razor Blade Guards for Dermatology
Segmented finger and blade guards prevent accidental cuts from sharp edges while maintaining ergonomic control.
