Incision Instruments TRIZ Cases

A cap displacement mechanism moves protective caps out of the active lancet travel path within a multi-lancet cartridge.

A cutting tool with angled blades enables precise horizontal tendon incision through a small surgical access point.

Dynamic curvature adjustment of a flexible shaft orients the cutting edge flush against tissue, minimizing damage to surrounding healthy structures.

Segmented caddy with tailored slots constrains cutting broaches to eliminate rotation risks while enabling seamless stem assembly.

Anchoring and channel creation enable precise tissue core extraction for accurate diagnosis.

Merged suction channel and flexible blade reduce instrument complexity and minimize occlusion during tonsillectomy.

A cannulation device uses a retractable wedge and fixed blade to pierce vessels through small access sites.

Disposable scab separation device with integrated cover prevents bacterial contamination during vascular access.

Segmenting dissection through the orbital septum creates a clear surgical field that reduces tissue damage and bleeding during enucleation.

Curved guiding tracks direct the blade member to reduce skin pain while maintaining reliable blood sampling reliability.

Segmented balloons independently compress the radial and ulnar arteries, preventing radial artery occlusion during hemostasis.

A scalpel locking slide secures the blade via spring pressure to enable safe handling.

A surgical stapling head uses independent forward and backward helix tracks to guide an annular cutter along a metal cylinder member.

A buttonhole tool uses a scoop bevel to lift scab tissue from patient skin.

Inward projections in the knife housing channel prevent tissue residue from causing sticking during extended inactivity.

A minimally invasive surgical system uses a dynamic guide wire path to enable precise bone fixation implantation.

A pediatric surgical device combines a movable blade and tissue spreading jaws in one compact handle assembly for precise dissection.

Segmented ultrasonic osteotome heads bend laterally to expand operating space in transforaminal spinal surgery while minimizing soft tissue damage.

A surgical stripping knife uses a guide face to maintain cutting edge sharpness during tissue separation.

Segmenting continuous resection into discrete pixels via the PAD system prevents visible scarring while enabling repeated donor site harvesting.

Elastically flexible parallel members flank the blade slot, requiring sufficient force for engagement while a bridge member blocks access to reduce injury risk.

A multi-functional extraction tool integrates clamping, cutting, and gripping mechanisms to standardize the retrieval of subdermal implants.
