Suture Equipments TRIZ Cases

Segmented radially deployable members retract capsular tissue, reducing interference with burrs and shavers while maintaining a compact device structure.

A shape memory needle delivery device deploys multiple attachment devices through a single lumen without reloading.

Segmented drill guide and crimping mechanism align pilot holes to fixate glenoid bone grafts, reducing surgical complexity and complication rates.

An implantable actuator with anchors contracts to draw ventricular walls together, synchronizing mechanical motion with heart pacing.

A flexible wire with corpuscles anchors ligament grafts using a blocking screw, eliminating synthetic relay elasticity and bone compartment requirements.

Segmented actuator assembly moves distally along anchor extensions to seat spinal rods, reducing procedural time and operational complexity.

A dissolvable medical sealing device closes vessel wounds using physical erosion rather than chemical degradation.

A dural sealing system uses a guiding thread and transfer device to deploy an implant.

Removable punch shaft eliminates metal fragment residue in bone openings while the expanding hollow body provides reliable suture fixation.

A suture device with a needle feeding assembly and anti-backoff mechanism for precise tissue penetration control.

Optimized molecular weight ratios in these polymer blends resolve the trade-off between rapid absorption rates and high initial mechanical strength.

Imaging a guide pin with radial markings reveals exact positioning and depth to select the correct fastener length, eliminating trial-and-error screw placement.
