Skin Implants TRIZ Cases

Gamma irradiation sterilizes acellular dermal allografts while preserving tissue ductility and pliability for surgical use.

A single-process method creates a bilayer scaffold by mixing polymers and inducing phase separation through high-speed stirring.

Freezing adipose tissue extract creates an ice crystal template that guides cellular organization and promotes neovascularization in damaged skin.

Segmented silicone anchor with tunnel retains collagen ligatures to resolve anchoring strength versus complexity trade-off.

A bioerodible conductive tissue scaffold combines conducting and biodegradable polymers to support cellular processes.

Segmented cutting edges separated by slits allow curled roots to pass without contact, preventing damage during tissue penetration.

Fluid irrigation reduces desiccation forces and mechanical stress on follicles, increasing viable graft yield while maintaining extraction precision.

Clinician-adjustable slit porosity in a silicone dressing manages exudate flow while preventing wound desiccation and infection.

Segmented receptacles and an automated intermediary mechanism resolve the trade-off between storage complexity and implantation productivity.

A silicone hair implant anchor uses a fracture line to fragment for removal and a porous structure to support collagen growth.

Visual servoing guides a robotic arm to align tools with scalp topography, reducing tissue trauma during automated follicular unit implantation.

Using gingival fibroblasts overcomes dermal cell scarcity in large burns while reducing excessive scarring via controlled scaffold release.

Segmented dermal papilla and epithelial cells self-organize into functional follicles, bypassing donor site limitations.

A biocompatible infra-orbital implant features a skin tone correction surface that reflects light to neutralize dark circles beneath the eye.

An interconnected cartridge system uses an indexing mechanism to switch between storage units, eliminating downtime during hair transplantation procedures.

A biodegradable collagen scaffold induces capillary flow to direct new lymphatic vessel formation.

A wound in-situ printing device deposits bio-inks to form layered tissue structures directly on the wound surface.

A vacuum suction device loads hair grafts into implantation needles without manual handling.

Segmented needle channels and core shafts reduce scalp damage while ensuring secure follicle placement during transplantation.

Automated hair transplant device uses a pressing pole to secure follicles during needle insertion.

Co-culturing dermal papilla cells with keratinocytes creates proto-hairs, addressing limited donor hair availability for transplantation.

Enzymatic and ionizing radiation processing removes immune-reactive cells from dermis while preserving the extracellular matrix structure.

A follicular unit removal tool uses a pivotally movable retention member to grip specimens during extraction.

Beveled denticulations on a cylindrical punch body distort tissue into an ellipse aligned with Langer's lines, reducing healing time and scarring.

A single device integrates vacuum blister raising and cutting mechanisms to streamline skin graft harvesting procedures.

PCR screening of porcine donors detects latent pCMV, reducing rejection rates and extending graft survival.
