Microtome and cryostat

摘要

A microtome comprising a head 32 which holds a sample, an alignment mechanism 50 which aligns the head 32, a body portion 42 which is provided on a back face side of the alignment mechanism 50, a cylindrical coupling portion 41 which couples the body portion 42 with the head 32, a temperature controller 34 in the head 32, and refrigerant piping 40 and electrical wiring 46 for the temperature controller 34, and the alignment mechanism 50 includes a spherical member 68 coupled with the back face side of the head and having a spherical outer periphery and includes retainer portions 70 and 71 retaining the outer periphery of the spherical member 68 slidably along a spherical surface, the spherical member 68 has a through hole 74 which communicates with the hollow portion 43 of the coupling portion 41, the refrigerant piping 40 and the electrical wiring 46 are connected with the temperature controller 34 in the head 32 through the through hole 74 of the spherical member 68 and the hollow portion 43 of the coupling portion 41.

主权项

1. A microtome comprising:
a cutting blade attached to a blade holder; a head which holds a sample so that a front face side of the sample faces the cutting blade; an alignment mechanism which is provided on a back face side of the head and aligns said head so that the head is rotatable in a vertical direction and is rotatable in a horizontal direction perpendicular to the vertical direction; a body portion which is provided on a back face side of the alignment mechanism and has a contact separation mechanism allowing the head to contact with and separate from the cutting blade; a cylindrical coupling portion which has a hollow portion formed in its center and couples the body portion with the head; a temperature controller provided in the head for cooling or heating the sample held by the head; and refrigerant piping for circulating a refrigerant in the temperature controller, and electrical wiring for the temperature controller, wherein: said alignment mechanism includes a spherical member coupled with the back face side of the head and having a spherical outer periphery, and a retainer portion for slidably retaining the outer periphery of the spherical member along the spherical surface; in said spherical member, a through hole communicating with the hollow portion of said coupling portion is formed; and said refrigerant piping and electrical wiring are connected with the temperature controller in the head through the through hole of the spherical member and the hollow portion of the coupling portion.
