Surgical Pincettes TRIZ Cases

Interlocking gears drive opposing rotating members to squeeze blackheads, preventing fingernail cuts and bacterial contamination.

Segmentation principles distribute donor site trauma across multiple micro-grafts while sensor feedback ensures precise timing for cleaving blisters.

Pivotable fingers expand outwardly to provide controlled gripping, reducing tissue trauma during surgical procedures.

Thermoelectric heating and cooling of a shape memory alloy clip enables reversible jaw closure, restoring blood flow without tissue trauma.

Integrated suction ports and a micro-hook blunt dissecting tip merge multiple surgical functions into a single forceps instrument.

HFO-1234yf aerosol spray immobilizes ticks via freezing, preventing disease transmission during removal.

A concave bearing surgical instrument supports organs through anatomically matched geometry.

Opposing tweezer arms encase lesions with canisters, protecting collateral tissue from damage.

A surgical instrument uses a pivoting lever locking element to secure the actuated position.

A surgical instrument features a push-push locking mechanism with a transversely pivotable lever and return spring.

An intermediary loading catheter guides band deployment cords through complex lumens, reducing manual difficulty and preventing cord tangling during assembly.

Anchoring the tenaculum clamp to the speculum frees the surgeon's hand and improves visibility during gynecological procedures.

Vacuum inversion pulls the distal appendage into an inner scaffold while an outer stent anchors the device to prevent dislodgement.

Segmented rod portions with wire-actuated joints rotate the distal end to navigate deep brain structures without colliding with an endoscope.

Axial gripper mechanism actuates pliers via compression springs to extract ticks without head tearing, eliminating complex thread drives.

A surgical instrument lever mechanism transmits handle movement to a drive element via angled levers that shift angular position during actuation.

A resilient tongue locks the tweezer halves inside the sleeve to prevent accidental release during handling.

A laparoscopic tissue holding device uses negative pressure suction to mechanically couple and secure biological tissues for precise surgical manipulation.

Trocar-deployed suction assembly positions organs using controlled vacuum and foam cushioning to prevent barotrauma.

A unified housing integrates micrograft generating and transferring stations to streamline skin grafting workflows.

Segmentation and hydraulic principles enable controlled stone collection, resolving procedure time and recurrence trade-offs.

Segmented guides prevent tip scissoring while preserving tactile feedback during precise tissue grasping.

Segmented clamp mechanism enables precise repositioning of inflatable cuff to achieve complete epicardial occlusion without open chest surgery.

A transvaginal surgical device captures and relocates a gestational sac to the uterus using an expandable frame.

Inverting the LAA allows an isolator to secure closure, preventing clot release during manipulation.

Replaceable boxwood tips on metal arms prevent surface scratching while maintaining durability.

An external magnetic control assembly applies force to a laparoscopic grasper, enabling remote tissue manipulation without increasing access site crowding.

A stapling device uses an indexing mechanism to advance a cartridge with multiple groups of offset staple slots, enabling successive tissue plications without reloading.
