Interchangeable instruments use antagonistic tendons and capstan shafts to deliver multi-degree-of-freedom tissue manipulation.

A surgical impactor array uses indexed engagement for rotational or axial offsets, supporting navigation accuracy and user positioning.

This case combines tissue displacement, thermal scarring, spacers, and fixation to reduce organ size and preserve durable restriction.

Alternating adhesion and suppression strips support laminated disease and normal cardiomyocyte sheets for pre-transplant assessment.

A reloadable clip assembly lets one endoscopic applicator deploy successive tissue clips without repeated device exchanges.

A tracked instrument maps pelvic landmarks to calculate acetabular rotation and pelvic planes, reducing manual registration effort.

A hand-held robotic instrument uses actuators and visual guidance to position surgical tools while users stay focused on the site.

Differential robot-arm tolerances preserve surgical instrument accuracy under external forces.

Expandable foam conforms to variable LAA anatomy while internal anchors enable verification, repositioning, and secure sealing.

Integrated strain gages and other sensors let surgical instruments adjust operation as conditions change, improving precision and safety.

Circle fitting from rotating marker positions calibrates robot tool-axis orientation without precise marker-array geometry.

Central feedline connectors keep surgical handpieces in place through cleaning, servicing, and sterilization, reducing contamination.

Stoppers constrain the protective tube axially while allowing rotation, helping cut stenotic lesions without damaging the guide wire.

Segmented re-registration links X-ray and ultrasound tracking without extra X-ray imaging.

A ferromagnetic layer limits metal and liquid signal distortion, enabling reliable RFID identification in ultrasonic medical inserts.

A strap lock, tissue stop, leaf spring, and distal finger simplify buttress attachment while supporting stable tissue reinforcement.

A gearbox lock keeps the knife blade secured in transit, then enables precise cutting after robotic coupling.

A balloon anchors the catheter while pulsed light generates acoustic waves that fracture calcified or fibrous vascular lesions.

A base plate, measuring arm, and pivotable cut guide support precise, repeatable tibial osteotomy cuts and biplanar correction.

Manual ligament-tension sensing is subjective; a removable disposable pod sends real-time distraction-force data to the surgical computer.

Active pull-wire control straightens flexible devices during retraction, reducing contact forces.

A fluid-path esophageal heat transfer device supports hypothermia control, minimizes shivering, and preserves gastric access.

External magnetic fields rotate and move the work member, enabling catheter steering and thrombus fragmentation with less vessel load.

A catheter rotates and twists the appendage, then secures the tissue to support closure without a conventional plug.

A twisting implant helps occlude the left atrial appendage while limiting migration and leakage.

This case uses real-time staple defect detection to adjust firing speed, pauses, timing, and clamp pressure during surgery.

Rotational deployment twists the left atrial appendage, securing occlusion while limiting blood exposure, leakage, and thrombus risk.

Tensile-actuated or magnetic expansion enlarges the catheter mouth at the target site for more effective thrombus aspiration.

A larger distal outlet and smaller proximal outlet improve tube flushing around the push rod, removing surgical contaminants.

An attachable auxiliary observation device provides direct backup viewing when a surgical microscope display fails.

This vascular treatment case combines neck flow diversion and sac packing to limit recanalization and promote endothelialization.

A tissue stop and strap lock secure the anvil buttress, limiting migration and simplifying attachment during surgical stapling.

See how staged light intensity and skin cooling reduce discomfort while preserving effective hair removal efficacy.

A self-expanding sealing assembly supports clampless hole formation while maintaining blood flow and improving suturing visibility.

A separated sensor bracket and ankle clamp simplify tibial axis registration while supporting accurate cutting-guide alignment.

This robotic surgery adapter uses a stretchable membrane and rigid frame to transmit linear and roll actions while preserving sterility.

An expandable downstream filter and proximal valve capture embolic material while enabling controlled drainage from the treated vessel.

Horizontal moveable engagement stabilizes sterile adapter connections, distributing force evenly and improving surgical robot precision.

Resonant beacon tags improve counting of retained surgical items despite material interference.
