Surgical Forceps TRIZ Cases
- Surgical Handling Device Rod Coupling Rotation
A handling device uses a sliding rod coupling to enable tool rotation within curved micro-invasive surgical instruments.
- Articulating Ultrasonic Surgical Instrument with Multi-Plane Flexible Interconnects
A surgical instrument uses perpendicular flexible interconnects to enable multi-plane articulation of the distal end effector assembly.
- Ultrasonic Surgical Instrument Articulating End Effector
Bendable waveguide and articulating shaft improve cutting precision while managing device complexity through dynamic configuration.
- Selectable Handle Biasing for Surgical Jaws
A selectable bias mechanism in a surgical handle lets surgeons choose open or closed jaw positions, preventing uncontrolled opening that damages tissue.
- Surgical Clip with Penetrating Lock and Pivoting Applicator
A pivoting applicator tip positions the clip precisely, while a severable hinge allows safe removal without damaging the vessel.
- Tissue Approximation Device for Scarless Wound Closure
A tissue approximation device uses rake members to grip wound edges and apply tension for closure.
- Rotatable Wrist Linkage for Minimally Invasive Surgical Instruments
Nesting the wrist inside the rod body reduces the turning radius, enabling rotation in narrow spaces without instrument interference.
- Actuation Mechanisms for Tissue Specimen Retrieval Devices
Pin-driven actuation pivots jaws to deploy a specimen bag, enabling intact retrieval through restricted access openings.
- Laparoscopic Instrument Hinged Gripping and Rotational Actuation
Hinged movable gripping members and annular actuator bodies enable multi-plane rotation while reducing finger effort during complex procedures.
- Ultrasonic Probe Cylindrical Engagement Portion Design
Segmented titanium and aluminum design reduces material loss while maintaining structural integrity.
- Detachable Pivotable Jaws for Permanent Hemostasis
Rotatable jaws and a deformable driver frame achieve permanent hemostasis by overcoming limited grasping capacity in gastrointestinal perforations.
- Clip Unit Flap Retaining Mechanism for Ligation Alignment
A clip unit fastening ring includes a flap retaining unit that holds the expansion extent of outward expanding flap parts.
- Laparoscopic Device Distal Handle Mimicking Motion
A laparoscopic device uses a distal handle and mechanical transmission to mimic actuator motion at the end effector assembly.
- Detachable End Effectors for Modular Surgical Devices
Segmented design allows remote attachment of multiple end effectors, eliminating frequent instrument exchange through narrow working channels.
- Ultrasonic Surgical Instrument Rigidizing Articulation Drive
A surgical instrument uses an articulation control assembly to lock and tension drive members for precise end effector positioning.
- Tonsil Forceps with Cradling Grasping Members
Curved grasping members cradle the tonsil, preventing fragmentation during resection.
