An integrated piston and vacuum chamber simplify cervix engagement while reducing thrust forces, tissue damage risk, and manufacturing complexity.

A hollow center lets a helical spring-based auger move tissue through curved, flexible tubes for removal or delivery.

This thrombectomy catheter uses a wider distal opening and suction to improve clot capture while reducing distal vessel blockage.

A sealing mechanism switches vacuum states to grasp and release the cervix repeatedly without traumatic tenaculum teeth.

Vacuum ports and air-egress channels improve thermal contact while controlled suction helps limit bruising and tissue damage.

Interconnected joint segments and quick disconnects increase force transmission and support versatile surgical stapling end effectors.

Differential compression via non-uniform wall thickness secures the diverticulum while minimizing tissue damage risk.

Integrating the toggle lever with a leaf spring eliminates separate axial compression springs, reducing weight and simplifying disassembly for cleaning.

Protruding fixture on tissue clamp arms engages surgical tools to prevent slippage during vascular procedures.

An integrated sliding grasper pulls tissue into a spring-loaded pouch, preventing bunching and rupture during minimally invasive retrieval.

Vacuum suction draws gastric tissue onto a fixed jaw while a retractable jaw compresses the fold, reducing stomach volume without surgical trauma.

Nested expandable elements engage and capture clots to prevent fragmentation during vascular removal.

Pivoting an actuation lever aligns internal channels in a vacuum-actuated surgical grasper, modulating suction force to prevent tissue damage.

A microsurgical handle uses compressed actuation arms to extend and retract instrument joints with minimal finger effort.

A sleeve with band-support surfaces and a reciprocating tube advance ligating bands sequentially for tissue ligation.

A ureteral plug catheter occludes the lumen and uses an irrigation port to wash calculus toward the bladder.

A malleable guide rail and sliding suction cup rotate heart tissue via vacuum pressure, eliminating additional incisions.

A hexagonal edge structure on a surgical instrument handle creates a honeycomb pattern that increases friction and grip security.

Axial plunger movement shifts the seal between folded and spread positions to draw stone fragments into the device, resolving low stone-free rates.

Pin-slot control mechanism converts handle pivoting into axial tool movement, eliminating intermediate linkage levers to reduce assembly complexity.

Deflectable grasping platforms increase contact area during closure to resolve uneven pressure distribution and prevent tissue damage in ophthalmic procedures.

A manual ligator integrates suction and a band magazine for one-handed tissue ligation.
