Device for producing a three-dimensional structural cell
A device 2 for producing a three-dimensional structural body has an accommodating plate 3 in which an accommodating recess portion 3 a for accommodating a cell mass 1 is formed, a support body 4 provided with a plurality of needle-shaped bodies 6 penetrating the cell mass, a suction nozzle 19 for adsorbing/holding the cell mass, and structure 20 for moving the suction nozzle.
1. A device for producing a three-dimensional structural cell, comprising:
an accommodating plate comprising an accommodating recess portion formed therein and containing one cell mass;
a support body provided with a plurality of needle-shaped members;
a suction nozzle having a tubular adsorbing portion for adsorbing/holding one cell mass at a tip end thereof;
a moving mechanism for moving and elevating the suction nozzle;
a lower camera for photographing the cell mass accommodated in the accommodating recess portion of the accommodating plate; and
a controller configured to measure the outer diameter dimension of the cell mass in the accommodating recess portion photographed by the lower camera to determine whether or not to adsorb and hold a cell mass having an outer diameter that does not reach a predetermined outer diameter dimension larger than the inner diameter of the tubular adsorbing portion, control the moving mechanism to lower the suction nozzle so that the cell mass is adsorbed and held by the tubular adsorbing portion and to move the suction nozzle above a specified needle-shaped member on the support body for a cell mass having an outer diameter that reaches the predetermined outer diameter dimension, and move the suction nozzle in an axial direction of the needle-shaped member to stick and penetrate the cell mass by the needle-shaped member and insert the needle-shaped member into the adsorbing portion so as to push in the cell mass.
2. The device for producing a three-dimensional structural cell according to claim 1 , wherein intervals between adjacent needle-shaped members in the support body are such that cell masses stuck by the respective needle-shaped member are brought into close contact with each other.
3. The device for producing a three-dimensional structural cell according to claim 1 , wherein the lower camera is positioned below the suction nozzle for photographing the suction nozzle, an upper camera is positioned above the support body for photographing the needle-shaped members and the controller is configured to control the moving mechanism on the basis of the position of the adsorbing portion of the suction nozzle photographed by the lower camera and the tip end position of the specified needle-shaped member photographed by the upper camera and move the suction nozzle adsorbing/holding the cell mass to above the specified needle-shaped member.
4. The device for producing a three-dimensional structural cell according to claim 3 , wherein the controller is configured to move the suction nozzle when a cell mass adsorbed/held by the suction nozzle is stuck by the tip end of the needle-shaped member and the tip end of the needle-shaped member photographed by the upper camera is not located within a specified range to a position such that the tip end of the needle-shaped member is located within the specified range.
5. The device for producing a three-dimensional structural cell according to claim 3 , wherein the accommodating plate is transparent and the lower camera can be located below the accommodating plate by the moving mechanism.
6. The device for producing a three-dimensional structural cell according to claim 1 , wherein the controller is configured to determine whether or not the cell mass has an appropriate shape on the basis of an image of the cell mass in the accommodating recess portion photographed by the cell mass camera so that the cell mass having an appropriate shape is adsorbed and held by the suction nozzle and the cell mass having an inappropriate shape is not adsorbed and held by the suction nozzle.
