         10 . The artificial dura biomedical device as claimed in  claim 8 , wherein the connecting element comprises a base, a first engaging portion and a second engaging portion, the first engaging portion and the second engaging portion are installed at two opposite surfaces of the base, the first engaging portion is inserted into the partial skull, and the second engaging portion is inserted into the artificial dura. 
     
     
         11 . The artificial dura biomedical device as claimed in  claim 8 , wherein the connecting element comprises glue. 
     
     
         12 . The artificial dura biomedical device as claimed in  claim 1 , wherein the connecting element comprises a plurality of protrusions and grooves, the protrusions are installed on the artificial dura, the grooves are installed on the partial skull, and the protrusions are engaged with the grooves. 
     
     
         13 . The artificial dura biomedical device as claimed in  claim 1 , further comprising a plurality of pads and a ring, wherein the pads are installed on the ring, the ring binds the artificial dura and the partial skull, and the pads are installed between the connecting element and the artificial dura for increasing friction. 
     
     
         14 . An artificial dura biomedical device, combined with a partial skull cut from a whole skull, comprising:
 an artificial dura;   wherein the artificial dura and the partial skull respectively comprise a plurality of protrusions and grooves, and the protrusions are engaged with the grooves for fixing the partial skull to the artificial dura.   
     
     
         15 . The artificial dura biomedical device as claimed in  claim 14 , wherein the protrusions and grooves are wedge shaped. 
     
     
         16 . The artificial dura biomedical device as claimed in  claim 14 , wherein the artificial dura is liquid at an initial state, and then the liquid artificial dura transforms into a colloidal or solid artificial dura. 
     
     
         17 . A brain surgery method utilizing an artificial dura biomedical device, the steps comprising:
 fixing an artificial dura to a partial skull; and   fixing the partial skull with the artificial dura to a cut hole of a whole skull.   
     
     
         18 . The brain surgery method as claimed in  claim 17 , further comprising:
 cutting a partial skull from a whole skull.   
     
     
         19 . The brain surgery method as claimed in  claim 17 , further comprising:
 drilling a hole on the partial skull.   
     
     
         20 . The brain surgery method as claimed in  claim 17 , further comprising:
