Title:
VIBRATION TYPE MICRO INJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/004407
Kind Code:
A1
Abstract:
A vibration type micro injection device capable of ensuring smooth piercing
with improved accuracy and efficiency when membranes having different natures
such as a pellucid zone including a fertilized egg, a cell membrane and nuclear
membrane are to be pierced. A vibration type micro injection device comprises
a vibrator (28) connected in series with a micro pipette (8) and having a housing
to which a piezoelectric actuator (29) is mounted, and a signal regulator (21)
for regulating an electric signal applied to the piezoelectric actuator (29),
wherein vibration is applied in the axial direction of the micro pipette (8) via
the vibrator (28) having a housing by inputting an electric signal to the piezoelectric
actuator (29). Therefore, it is possible to ensure smooth piercing with improved
accuracy and efficiency when membranes having different natures such as a pellucid
zone including a fertilized egg, a cell membrane and nuclear membrane are to be
pierced.
