Abstract: The present invention addresses the problem of providing a device for training in ophthalmic surgery that can be used for training in glaucoma surgery. The problem can be solved by a device for training in ophthalmic surgery including: a simulated-eyeball pedestal having a recess into which a simulated eyeball can be directly or indirectly inserted; a simulated eyeball insertable into the simulated-eyeball pedestal, or a member for retaining a simulated eyeball that retains a simulated eyeball, the member for retaining the simulated eyeball being insertable into the simulated-eyeball pedestal; and a mechanism for generating a restoring force that generates a force for restoring a position of the simulated eyeball or the simulated-eyeball retaining member toward a normal state with respect to the simulated-eyeball pedestal; the simulated eyeball or the member for retaining the simulated eyeball rotating along the recess of the simulated-eyeball pedestal.

Abstract: The object is to provide an evaluation model that can evaluate how much external force is being applied to a brain organ and/or a cranial bone during an endoscopic endonasal surgery. The object can be achieved by an evaluation model for endoscopic endonasal surgery including: a simulated head part; and a distortion sensor, in which the simulated head part includes a simulated cranium part, the simulated cranium part includes a simulated nasal cavity, and the distortion sensor is arranged in a part of the simulated head part.

Abstract: Provided is a microparticle separation system capable of continuously separating microparticles from a solution in a short period of time in which microparticles having different particle diameters are mixed, without the need to use antibodies or the like. The microparticle separation system comprises a microparticle separation chip; a thin plate for a sample liquid; a thin plate for a sheath liquid; and suctioning means and/or a suctioning device for suctioning the sheath liquid; and the microparticle separation chip comprises a single capture site for capturing to-be-captured microparticles being formed using the at least three pillars having one end provided on the substrate and the other end open upward.

Abstract: Provided is a microchannel chip, for microparticle separation, which can continuously separate microparticles, from a solution in which microparticles of different particle diameter are mixed, without needing to use an antibody or similar, and without causing clogging. Also provided are a microparticle separation method and a system for microparticle separation using the chip. Microparticles can be captured by using the microchannel chip for microparticle separation, the microchannel chip being characterised by being provided with a plurality of main channels and capture portions that are wider than the main channels and at least one of which is provided to each main channel.
