Robotic Prostheses For Human Faces 111
holy_calamity writes "New Scientist reports on a patent application that suggests implanting polymer muscles beneath the skin of people suffering paralysis of the face to give them control of their features. The technique has already been used successfully to reanimate the eyelids of human cadavers. Movement could be returned to other facial features and even paralyzed limbs in the same way, the surgeons at University of California Davis say. The full patent application is also available on the WIPO site."
Cadaver control? (Score:3, Informative)
The technique has already been used successfully to reanimate the eyelids of human cadavers.
Hmmm. I had no idea that cadavers had the capacity to control robotic eyelids :)
From the abstract:
Metbods: With use of four cadaver heads, an extended upper and lower blepharoplasty incision was used to secure an upper and lower expanded polytetrafluoroethylene implant in the medial orbital wall and tarsal plates. The slings were passed through a hole drilled in the lateral orbital wall or around a titanium screw. Lateral pull on the sling created eyelid closure, and the necessary distance of pull was measured. Results: The eyelid sling mechanism functioned to achieve complete eyelid closure. Less tension was required for eyelid closure when the sling was placed in both eyelids (3 mm of pull instead of 6 mm). Conclusions: The application of artificial muscle to a range of problems that affect both patient morbidity and quality of life is promising. Eyelid closure was created in a cadaver model using a novel sling, but future studies will need to address the feasibility of a prototype artificial muscle eyelid device in humans.
