Incision Instruments TRIZ Cases
- Medical Device with Restriction Mechanism for Urethral Implantation
A medical device uses a restriction mechanism to fix dissection direction during urethral implantation.
- pH-Sensing Surgical Tool for Real-Time Cancer Cell Detection
A surgical tool with pH-sensitive sensors identifies cancerous tissue during operations.
- Mini Safety Scalpel Retractable Blade Locking Mechanism
A mini safety scalpel features a retractable blade locked into three positions for secure concealment.
- Lancing Device with Lateral Slicing Mechanism
A lancing device drives a lancet tip laterally through a housing aperture to create a slicing action.
- Reusable Metal Scalpel Handle With Interlocking Blade Lock
An interlocking blade lock arm secures surgical blades to prevent accidental injury during fitting and removal while reducing breakage risks.
- Cataract Chopper with 110-Degree Angled Needle-Head
A surgical chopper features a needle-head angled at 110 degrees to minimize hand rotation during cataract operations.
- Expandable Intravascular Catheter with Incising Struts for Plaque Fragmentation
An expandable catheter uses radial struts to deploy incising elements that fragment atherosclerotic lesions during angioplasty.
- Magnetic Lancet Driver with Feedback Control for Blood Sampling
Electromagnetic drivers move a lancet via feedback loops, eliminating mechanical recoil to ensure reliable spontaneous blood sample generation.
- Surgical Tooling as Optical Pointer for Sterile GUI Control
A system tracks surgical tool movements via image sensors to control a graphical user interface without physical contact.
- Trocar Incision Blade Extending Beyond Cannula Diameter
Segmenting the incision blade from the cannula allows its width to exceed the tube diameter, reducing insertion resistance while maintaining precise placement.
- Concurrent Speech Handling via Dynamic Delay and Priority Policies
Dynamic speech delay mechanism adjusts output timing based on participant priority to manage overlapping audio streams.
