Surgical Saws TRIZ Cases

A hard locking member compresses a softer surface to secure sliding guide parts with fine adjustment and easier use in fluid-filled surgery.

A cutting block with a reference foot and probe combines femur sizing and saw guidance to shorten knee resection steps and reduce alignment errors.

A rotatable cutting slot block enables precise multi-planar Lapidus bone cuts through small incisions, reducing scarring and infection risk.

A spacer-guided bone preparation guide aligns metatarsal and cuneiform cuts for accurate multi-planar realignment in bunion correction.

Angled cut and targeting guides improve bone cut accuracy and wire fixation stability in hallux valgus osteotomy procedures.

A guided frame, feeler, and correction unit enable precise bone alignment and implant placement with less invasive cutting and fewer X-rays.

Segmented chain links let the holder conform to different patella shapes while maintaining secure grip and stable support for resection tools.

A multi-guide osteotomy block aligns the cuneiform and metatarsal for precise bunion cuts without repeated block changes, reducing procedure time.

Adjustable guide surfaces let surgeons adapt patient-specific bone resection guides during surgery while preserving prosthesis alignment accuracy.

An adjustable compression-distraction mechanism aligns and stabilizes the first tarsometatarsal joint for repeatable hallux valgus correction.

An adjustable guide shifts the distal femoral cutting plane relative to the IM canal for predictable flexion gap control and implant alignment.

Specialized cut guides and compressor-distractors improve lesser metatarsal realignment accuracy while reducing tissue damage in foot fusion procedures.

Guide pins steer a surgical saw to form a cross-joint keel slot, enabling stable bone fixation that resists migration and rotation.

An in vivo modular trial assembly preserves component positions during revision knee arthroplasty, cutting alignment and documentation burden.

Convex end stop surfaces cut friction and wear in a surgical cutting guide, enabling larger tool inclination and more precise cuts.

A spring-biased retention member secures surgical accessory tools in a drive bore for stronger torque transfer, lower wear, and easier attachment.

Wedge-shaped cuts at the second and third tarsometatarsal joints enable precise metatarsal rotation, fixation, and foot realignment.

A proximal rib and side-abutting reinforcing member stiffen a reciprocating surgical saw blade to limit stress, deflection, and failure.

A fixed patella clamp and movable cutting guide enable separate angle and height adjustment without repositioning during knee surgery.

A movable cutting guide lets surgeons adjust patella cutting height and angle separately without re-fixation, improving resurfacing accuracy.

A dual-stiffness cassette clamps the saw blade with dampers to reduce blade whip while enabling secure, easy attachment and removal.

Multiple burrs and blades on one osteotomy instrument create precise wedge-shaped bone cuts in a single pass, reducing time and inconsistency.

Angled apertures and targeting holes guide bone cuts and wire placement in hallux valgus surgery, improving fixation accuracy with simpler tools.

A ball-joint and quick-release cutting guide speeds bone resection setup while maintaining stable slot positioning and surgical tracking.

Parallel longitudinal and transverse cuts create movable first metatarsal segments for precise multi-plane realignment and gap filling.

Angled apertures and wire holes guide bone cuts and fixation to improve alignment and stability in hallux valgus correction.

Orthogonal pin holes and a flex plate help control distal femoral resection planes, improving flexion gap and implant alignment in revision TKA.

Magnets and spring-assisted adjustment replace thumbscrews in a humeral cut guide, improving alignment, reducing vibration, and speeding resection.

A passive sliding guide keeps the surgical saw blade aligned against bone to prevent buckling, improve cut precision, and preserve visibility.

Bone cutting guides create wedge openings at tarsometatarsal joints to simplify metatarsal realignment and fixation for deformity correction.

A split surgical guide uses reference pins to keep osteotomy placement precise while reducing guide bulk, incision size, and tissue disruption.

A universal tibia alignment guide uses resilient clamping and a telescopic decoupling shaft to reduce trauma, simplify handling, and keep resection alignment precise.

Patient-specific alignment blocks and cut guides improve osteotomy cut accuracy and bone positioning in joint deformity correction.

A two-position locking adapter secures removable tools on a surgical instrument without modification, damage, or handpiece removal.

Specialized cut guides and compressor-distractors improve lesser metatarsal realignment and fusion while limiting scarring and tissue damage.

Adjustable cannulated cutting guides improve foot and ankle cut alignment, balancing surgical precision with anatomical adaptability.

Modular alignment and cutting components support precise total ankle replacement with mini c-arms while reducing procedural complexity and radiation exposure.

A ball-and-socket patellar drill guide keeps flat contact on the resected patella while preserving implant hole alignment independent of cut angle.
