[0023] During use, by driving the gear 21 to rotate forward by the power component 22, the rack 32 can be driven to rise by the gear 21. During the rising process of the rack 32, the guide rail 31 slides along the guiding seat 50. At this time, the object picking and placing device 40 rises along with the linkage device 30. By driving the gear 21 to rotate reversely by the power component 22, the rack 32 can be driven to descend by the gear 21. During the descending process of the rack 32, the guide rail 31 slides along the guiding seat 50. At this time, the object picking and placing device 40 descends along with the linkage device 30. Since the Z-axis motion mechanism of a medical device provided by the present invention, on the basis of adopting the support base 10, the driving device 20, the linkage device 30, and the object picking and placing device 40, combines the driving device 20 with the gear 21 and the power component 22, combines the linkage device 30 with the guide rail 31 and the rack 32, and at the same time slidably matches the guide rail 31 with the guiding seat 50. By driving the gear 21 to rotate by the driving device 20 and driving the rack 32 to move by the gear 21, the object picking and placing device 40 can be driven to lift, and at the same time, the stability of the lifting of the object picking and placing device 40 can be improved, and the weight of the Z-axis motion mechanism can be reduced.
