Incision Instruments TRIZ Cases
- Surgical Handle With Rotating Carrier For Multiple Blades
A rotating carrier mechanism stores multiple blades within a single handle, reducing contamination risk during surgery.
- Safety Blade Dispenser with Verification System
A safety blade dispenser stores surgical blades in an orientation that allows users to attach tool handles without touching the blades.
- Ultrasonic Scalpel Composite Vibration for Soft Tissue Protection
A medical ultrasonic scalpel generates composite longitudinal, torsional, and bending vibrations to adapt to diverse surgical procedures.
- Retractable Safety Knife Tilt Track Mechanism
A retractable safety knife uses a tilt track mechanism to rotate and translate the blade between nested and extended positions.
- Color Changeable Dye for Medical Product Expiration
A color changeable dye composition indicates product expiration through redox reactions triggered by oxygen exposure.
- Expandable Intravascular Catheter with Incising Struts
Intravascular catheter featuring an expandable portion with incising elements and abrasive surfaces for tissue modification.
- Disposable Motor-Drive Loading Unit for Surgical Staplers
An electrically powered disposable loading unit automates the axial drive assembly, eliminating manual ratcheting fatigue during tissue stapling.
- Electromagnetic Lancet Module for Spontaneous Blood Sampling
A sampling module uses an electromagnetic driver to propel a lancet with precise control over penetration depth and velocity.
- Angled Ultrasonic Scalpel Bit for Narrow Space Surgery
An ultrasonic scalpel bit with an angled tip and protective protrusion concentrates energy at the cutting front.
- Modular Surgical Stapler Coupling for Variable Loading Units
Universality and segmentation principles enable a single instrument to accept multiple loading unit sizes, reducing procedure complexity.
- Surgical Adapter Assembly With Multi-Axis Drive Mechanism
Nested drive assemblies in the adapter assembly distribute loads across co-axial and offset axes to resolve adaptability versus complexity trade-offs.
- Dual Retractable Lancet Safety Scalpel with Segmented Handle
Segmented retractable lancet systems at opposite ends of a handle enable switching between two protected blades without changing the device structure.
- Rotatable Shaft Dissection Tool for Cell Colony Cutting
Helical grooves on a rotating shaft cut cell colonies in single passes, reducing dissection time and improving portion homogeneity.
- Parabolic Incision Medical Cutting Device
A pivoted medical cutting blade follows a parabolic path to generate smooth incisions.
- Subcutaneous Tunneling Tool With Depth Guard Prongs
Prongs on a tunneling tool constrain rod insertion depth and angle, resolving inconsistent pocket geometry that compromises sensor communication.
