Incision Instruments TRIZ Cases

Force fit connection between coupling link and tool eliminates helical springs, reducing component count and simplifying cleaning.

An asymmetric three-edge blade design lowers peak cutting forces and limits penetration depth to prevent tissue injury during skin puncture procedures.

A pre-loaded open cell element rehydrates during drilling to mark holes and deliver substances, resolving visibility and retention trade-offs.

A surgical passing tray uses a sliding holder and actuator to securely retain instruments during transfer.

Alternating blunt and reed tips distribute pressure uniformly, reducing patient discomfort while enabling clear skin reaction observation.

An automated medical aspiration system uses an ultrasound probe to guide a fluid aspirating cannula for precise targeting.

A detachable exhaust device with vents captures electrosurgical smoke plumes at the source, reducing visual impairment during laparoscopic procedures.

Co-molding a rigid metal cutting head to a flexible polymer shaft eliminates sterilization complexity while maintaining surgical precision.

A tissue closing apparatus uses flexible arms and a biasing mechanism to apply controlled closing forces.

Segmented movable guard minimizes accidental cuts while maintaining uniform grip comfort.

Ribbed syringe plunger rods use recycled resin blends to lower environmental impact without compromising biocompatibility or sterilization stability.

Segmented handle and disposable amorphous metal tips resolve sterilization costs and blade dullness trade-offs.

A surgical tool spring mechanism transmits tactile feedback, resolving lost tissue resistance cues during laparoscopic procedures.

A leaflet laceration device uses a moveable arm to position a cutting element against the anterior mitral leaflet.

Expandable catheter struts deploy incising elements and abrasive surfaces to fragment atherosclerotic material, eliminating high-speed motor complexity.

An attachment for a gas-assisted electrosurgical device employs an ElectroBond coated blade to reduce tissue necrosis and charring during plasma coagulation.
