Surgical Forceps TRIZ Cases
- Surgical Clamp with Angled Grippers for Metatarsal Fixation
Angled grippers hook metatarsal necks to fix bone position, avoiding interference with surgical instruments and preserving great toe joint motion.
- Endoscopic Grasping Device with Interlocking Teeth
Interlocking front teeth mesh to create a hemisphere-shaped distal tip, preventing gastrointestinal tract damage during object retention.
- Ergonomic Surgical Handle Assembly with Detachable Portion
A detachable handle portion interfaces with a fixed surgical instrument body to enable simultaneous control of clamping and power settings.
- Rotatable Jaws with Biasing Strip for Tissue Grasping
Rotatable jaws and a biasing strip engage tissue to resolve limited grasping capability in hemostatic devices.
- Surgical Handle Ratchet Mechanism Single-Button Release
A laparoscopic surgical handle integrates a cam button and pawl member to engage or disengage the ratchet mechanism.
- Surgical Clip Applicator Mouthpiece Segmentation
Segmented plastic mouthpiece and reusable steel handle lower production expenses without compromising closing force transmission for double-shank clips.
- Tissue Retrieval Bag with Reinforced Sidewalls
Reinforced sidewalls restrict directional stretching of the elastomeric pouch, enabling controlled volume adjustment for varying tissue sizes.
- Surgical Clip Jaw Projection for Secure Positioning
Inwardly protruding jaw projections enter longitudinal clip slots to guide and secure ligating clips during surgical application.
- Expandable Drill Bit for Combined Drilling and Grasping
An expandable drill bit performs drilling and remote grasping through one entry point, reducing contamination risk and procedure duration.
- Endoscopic Tool Coil Sheath Segmentation for Torque and Axial Force
Segmented single and multi strand coils resolve axial force loss during rotation follow up.
- Articulatable End Effector Cable Actuation for Multi-Plane Alignment
Cables transmit forces through the tube to articulate the end effector independently, resolving single-plane alignment limits.
- Surgical Wire Twisting Tool with Locking Jaws
Locking jaws secure the wire while a rotating member twists it, preventing breakage during one-handed operation.
- Bayonet Connection Anti-Rotation Cam for Microsurgical Instruments
A pivotable retractor uses a longitudinally movable cam to engage longitudinal slits in bayonet elements, securing the tool head connection.
- Ultrasonic Surgical Instrument Assembly Tool Torque Limiting
Torque-limiting mechanism prevents over-tightening while securing transducer and waveguide engagement in ultrasonic surgical instruments.
- Ultrasonic Cauterization Blade with Tapered Waveguide
Tapered ultrasonic waveguide slides within pivotable jaws to cut and seal large-diameter vessels.
- Surgical Clip Applicator Jaw Design for Visibility
An anvil jaw and slide member define an enclosed tissue receiving area, improving surgical site visibility during clip application.
