Surgical Instrument Support TRIZ Cases

Switching between PI and P control settings improves manual responsiveness while preserving precise autonomous drive control in mobile medical devices.

Spring-loaded retainers and a push-pin interface enable fast, secure surgical component mounting without tools or extra installers.

A dual-outlet hose manifold and air-permeable inflatable structure spread heated air evenly while limiting bend-induced pressure drop.

Remote arcuate and rotational control lets surgeons reposition a uterine manipulator without leaving the workstation or relying on blind assistant adjustment.

Adjustable coupling links let a surgical tool guide switch from rigid alignment to flexible correction, improving screw insertion accuracy.

Interchangeable mounting plates and alignment features let OR equipment mounts fit multiple manufacturers with faster reconfiguration and less redesign.

A radiused funnel inlet and distal counterbore ease angled instrument insertion while preserving precise trajectory guidance and reducing bore damage.

Housing actuators and cabling inside a cavity reduces open sections, raising torsional stiffness for more stable and precise robotic surgery.

Overlapping coaxial cross arms cut surgical robot arm footprint while improving instrument positioning flexibility and collision safety.

Nested yaw, pitch, and roll axes with rerouting pulleys give endoscope support high torque in a compact tip while reducing backlash and interference.

A cross-appendage retractor converts handle squeeze into prong expansion to keep incisions open, reduce tissue trauma, and avoid readjustment.

A radiused inlet guide tube accepts angled surgical instrument entry while protecting the bore and preserving precise trajectory control.

Independent translation and rotation actuators give surgical end-effectors four degrees of freedom for precise alignment in restricted spaces.

A spine-secured retractor with locking angle adjustment keeps nerve root retraction steady without assistant fatigue, reducing instability and nerve damage risk.

A spring-loaded sleeve and tension cable let one surgical stabilizer arm lock either ball or shaft tissue manipulators, reducing tool incompatibility.

Coordinated shift, yaw, and pitch motions let a surgical mounting plate align end-effectors accurately in limited spaces and restricted postures.

Bedside 3D image guidance and foot pedal control let one practitioner position a cannula more stably while reducing walking and radiation exposure.

Partially enclosed arm-support cavities route cables in rolling loops, preserving torsional stiffness for more stable and precise robotic arm motion.

A sleeve support braces the shaft sleeve against cutting loads, reducing deformation and maintenance needs in a surgical robot tool holder.

Hourglass-shaped blade receptacles and latches limit blade-head translation, rotation, and angulation while holding anatomy clear of the surgical field.

Robotic surgical instruments use cassette-mounted cable, rotation, and axial actuators for precise end-effector control in limited access areas.

Separate cable, rotation, and axial actuators enable precise end-effector movement through a compact robotic surgical cassette.

Segmented mounts and a disposable interface preserve the sterile barrier while enabling surgical component replacement.

Lateral supports compress epigastric tissue for stable sub-xiphoid access.

Separate stationary and rotation hubs simplify secure mechanical, electrical, and pneumatic connections during robotic instrument exchange.

Replacing mechanical clamps with magnetic attraction prevents hematoma formation while maintaining secure fixation on the tibia.

Diagonally opposed gear assemblies with opposite thread pitches translate limited robotic inputs into precise articulation while maintaining cable pre-tension.

Segmenting wrist and elbow motions allows multiple devices through one incision without trocar interference.

Segmenting the optical path via beam splitters creates side-by-side virtual images within the pupil, resolving alignment conflicts in stereoscopic imaging.

A spherical axis alignment mechanism prevents twisting friction during insertion, maintaining smooth control within the endoscope channel.

A gripping mechanism holds an outer tube via a supporting portion containing joint portions that adjust position and orientation.

Segmented blades translate and rotate to clear deep tissue obstructions, resolving the trade-off between exposure area and muscle disruption.
