Problems solved by technology

However, the clamping part of some existing microtome tissue has no cooling source, and the temperature of the tissue will increase and change during the slicing process, resulting in the inability to continuously and effectively slice
It needs to be removed and re-frozen to add slices for the second time, which is inefficient

Abstract

The invention discloses a sample caliper, and belongs to the field of biological slicing machines. The sample caliper comprises a base and a sample clamping mechanism arranged on the base and used for clamping a sample, wherein the base comprises an adjusting mechanism and a refrigerating system; the refrigerating system comprises a Peltier element arranged in the sample clamping mechanism and a liquid inlet pipe and a liquid outlet pipe which are connected to the base; the adjusting mechanism comprises a ball joint and a pushing assembly, and the ball joint comprises a ball seat and a joint ball arranged on the ball seat; and the liquid inlet pipe and the liquid outlet pipe are connected to the ball seat, a circulating groove is formed in the ball seat and surrounds the joint ball, and two ends of the circulating groove communicate with the liquid inlet pipe and the liquid outlet pipe respectively. According to the invention, the refrigerating system can refrigerate the sample clamping mechanism to indirectly refrigerate a sample, so that slice tissue is always kept in a stable low-temperature state in a slicing process, and the slicing effect is always kept consistent.

Description

technical field [0001] The invention relates to the field of biological slicers, in particular to a sample caliper. Background technique [0002] A biological slicer can also be called a tissue slicer. A biological slicer is a machine that cuts thin and uniform slices of tissue. Each cut is automatically advanced (towards the direction of the knife) by the slice thicknesser for the required distance. [0003] Fresh biological tissues are not easy to slice at room temperature, and generally need to be cryogenically frozen before sectioning. However, some existing microtome tissue clamping parts do not have a cooling source, and the temperature of the tissue will increase and change during the slicing process, resulting in the inability to perform continuous and effective slicing. It needs to be removed and re-frozen to add slices twice, which is inefficient. In addition, after some special uneven tissues are frozen, to cut out a complete tissue surface, the sample chuck mus...
