Alo te tate of te at of aptic an viual guiance evice wit foce feeack i peente ening te capte wit te eeac neceity an jutification of te coen P.D. topic.. Te efinition of a new active paallel tuctue fo ootic ugey Capte peent a new active yi paallel tuctue fo oientation an cutting in minimally invaive ugey PARASURG-9M coniting of te ootic moule PARASURG 5M wic pefom te poitioning in te ugical fiel an te active ugical intument PARASIM wic pefom te oientation of te en efecto in te ugical fiel. Kinematic ceme of te new paallel oot Stating fom a et of conition impoe y te ugical act wic wee efine togete wit te team of ugeon te kinematic ceme of a new oot i pupoe. Te capte continue wit te tuctual analyi of te oot an geometic moeling: fowa an invee meto followe y te etemination of te wokpace of te new tuctue eigne fo ootic ugey. Finally a valiation of te numeical eult fom te geometical moel i mae uing te CAD moel of PARASURG-9M moel.
