Surgical Staples TRIZ Cases
- Dual-Output Gearbox for Hand-Held Surgical End Effectors
Different surgical end effectors need different speeds and torque; a dual-output gearbox separates drive paths from one motor.
- Cable-Driven Surgical Stapler Articulation Beyond 60 Degrees
Flexible pushrods limit stapler articulation to 45–60 degrees, while cable drives enable wider positioning for angled tissue.
- Surgical Stapler Rotatable Cam for Sequential Staple Ejection
A rotatable cam sequentially advances segmented pushers to eject staples while a flexible shaft reaches difficult surgical sites.
- Rail-Guided Actuation Beams for Anti-Buckling Endoscopic Instruments
Rail-guided bearings support a surgical beam tangentially, preventing buckling during longitudinal actuation in smaller endoscopic instruments.
- Biodegradable Trocar Site Closure Clip for Hernia Risk Reduction
A biodegradable clip blocks the trocar opening after laparoscopy, reducing herniation risk without requiring full fascial closure.
- Anvil Buttress Loading Tool for Surgical Stapler Attachment
A loading tool transfers anvil buttresses to a surgical stapler, simplifying operating-room attachment and reducing procedural complexity.
- Manual-Fallback Surgical Stapler for Electric Mode Failure
Limit members disconnect both motor paths during failure, enabling safe withdrawal and manual completion of anastomosis.
- End Effector Control Mechanism for Tortuous Surgical Access
Elongated-member control pivots the end effector between parallel and angled positions for tortuous-path access and less patient trauma.
- Ultra-Low-Profile Surgical Stapling End Effector for Unilateral Sealing
See how a movable anvil and C-shaped clamping member create a compact end effector for unilateral endoscopic tissue stapling.
- Lead-Screw Actuation Assist for Uniform Linear Staple Formation
A motor, lead screw, and knob connector drive the stapler’s actuation knob axially, reducing hand fatigue and improving staple formation uniformity.
- Overlapping Staple Pattern for Surgical Stapler Seal Strength
Overlapping staple legs and a modified anvil increase staple density to strengthen seals and limit luminal leakage.
- Surgical Stapler Anvil With Laterally Varying Staple Pockets
Laterally varying anvil pockets form staples with distinct orientations to balance tight tissue compression and leak path resistance.
- Surgical Buttress Attachment Assembly for Taut Staple Formation
A movable block and resilient biasing member keep the buttress taut, limiting deformation and supporting flush staple formation.
- Variable-Mode Surgical Handle Assembly for Adaptive Staple Deployment
A mode-selection switch varies actuation-shaft advancement so surgical staplers can adapt staple deployment to tissue type and user fatigue.
- Cam-Driven Adapter Assembly for Articulating Surgical Loading Units
A rotatable cam and opposing articulation shafts let the surgical loading unit reach tissue at varied angles through a constrained access path.
