Simulation system for operating position of a pointer

A microinjection apparatus, which injects an object into a cell with a needle, acquires a first image that is an image of the cell at a first focal position and a second image that is an image of the cell at a second focal position, and decides a state of the cell based on a difference image obtained from the first image and the second image. Execution of such sequence of processing makes it possible to measure a state of a cell without involving human work and confirm the state of the cell in performing a microinjection, without a necessity of experienced skill, efficiently, and simply.

Microinjection apparatus and automatic focal point adjustment method

A microinjection apparatus has a trap plate which traps at least one cell, so as to fix a position thereof, a capillary needle which injects a substance into the cell trapped by the trap plate, a movement mechanism portion which thrusts a distal end of the capillary needle onto a in a lengthwise direction of the needle, and which withdraws the capillary needle in the lengthwise direction thereof, and a discharge control portion which discharges the substance from the distal end of the capillary needle, when the capillary needle has been withdrawn to a predetermined position by the movement mechanism portion.

Microinjection apparatus, trap plate and microinjection method

A microinjection apparatus of the present invention includes a needle-position polarity detecting unit that detects a position of the needle in the vertical direction at which a value of a differential aggregate distribution becomes the maximum in the situation in which a shape of the leading edge of the needle at a focal position narrows at the right. Moreover, a differential-average determining unit, based on a differential average of an image near the position detected by the needle-position polarity detecting unit, determines the lowest allowable position of the needle, which is a position at which a differential average exceeds a predetermined threshold.

Microinjection apparatus and microinjection method

A feed controlling apparatus that controls feeding of plural minute objects that flow along a channel of a fluid, and receive a predetermined process at a predetermined position, includes a detector that detects whether there is the object at the predetermined position, and a controller that controls feeding of the object to be supplied to the predetermined position based on a detection result by the detector.
