The invention discloses a clamping mechanism and method for
laser drilling of an artificial soft-bodied
artery vessel
stent. The clamping mechanism comprises a mounting seat, an electric clamping jawand a pneumatic elastic
mandril, wherein one end of the electric clamping jaw is connected with a mounting seat, a plurality of clamping arms are arranged at the other end of the electric clamping jaw; the pneumatic elastic
mandril comprises a
mandril body, a pneumatic
assembly and an inflating and exhausting
assembly; the mandril body comprises a clamping segment and a support segment; a plurality of clamping grooves are formed in the clamping segment, and each clamping arm can be clamped in the corresponding clamping groove; the pneumatic
assembly comprises an elastic air bag and an elasticexternal connecting layer; the elastic air bag is used for wrapping the support segment, and a vent hole is formed; the elastic external connecting layer sleeves the elastic air bag, and can be inserted into the vessel
stent; and the inflating and exhausting assembly is used for inflating air into the elastic air bag, so that the elastic air bag expands to enable the elastic external connecting layer to be abutted against the vessel
stent. The positioning errors of the vessel stent in the circumferential direction and in the axial direction can be reduced, the
laser drilling accuracy and the drilling quality are improved, the operation is simple, and the
laser drilling efficiency is improved.
