Description

一种收集盘及具有其的切片机Collection tray and slicer with the same
技术领域Technical field
本发明涉及切片机技术领域，尤其涉及一种收集盘及具有其的切片机。The invention relates to the technical field of slicers, in particular to a collecting tray and a slicer with the same.
背景技术Background technique
轮转式切片机适用于生物学、医学和工业研究领域中的薄石蜡切片的制作。轮转式切片机通常包括主体、样品定位装置、刀架和收集盘，收集盘围绕刀架的三面设置。把包埋有组织样品的石蜡块固定到样品定位装置上，通过主体中的进样机构、样品定位装置和刀架对石蜡块进行切片。在切片过程中，需要调试切片或者对石蜡块进行修正，这样会产生不必要的石蜡碎屑，这些石蜡碎屑散落在收集盘中。The rotary microtome is suitable for the production of thin paraffin sections in the fields of biology, medicine and industrial research. A rotary microtome usually includes a main body, a sample positioning device, a knife holder, and a collection tray. The collection tray is arranged around three sides of the knife holder. The paraffin block embedded with the tissue sample is fixed to the sample positioning device, and the paraffin block is sliced through the sampling mechanism, the sample positioning device and the knife holder in the main body. During the sectioning process, it is necessary to adjust the section or correct the paraffin block, which will produce unnecessary paraffin debris, which is scattered in the collection tray.
由于包埋于石蜡块中的组织样品通常是受污染或者受到细菌感染的生物组织，为了方便清洁、减少组织样品间的交叉污染，要求收集盘的表面具有不沾粘石蜡、易清洁等特性。Since tissue samples embedded in paraffin blocks are usually biological tissues that are contaminated or infected by bacteria, in order to facilitate cleaning and reduce cross-contamination between tissue samples, the surface of the collection tray is required to be non-sticky and easy to clean.
现有技术中，为了解决石蜡碎屑由于静电吸附作用沾粘在收集盘的问题，通常是在收集盘的表面喷涂防静电涂层。由于防静电涂层的厚度很薄，在使用中发生磕碰时，容易导致防静电涂层脱落。另外，在收集盘的表面喷涂防静电涂层也存在耐候性不足的问题。这些都会造成收集盘不具备长久有效的防静电吸附能力。In the prior art, in order to solve the problem of the paraffin debris sticking to the collecting tray due to electrostatic adsorption, an antistatic coating is usually sprayed on the surface of the collecting tray. Since the thickness of the anti-static coating is very thin, it is easy to cause the anti-static coating to fall off when bumps occur during use. In addition, spraying an antistatic coating on the surface of the collecting tray also has the problem of insufficient weather resistance. These will cause the collection tray to not have long-term effective anti-static adsorption capabilities.

Conductive media include but are not limited to carbon fiber, carbon black, metal fiber, metal powder, antistatic masterbatch, etc., and plastic particles include but are not limited to ABS (Acrylonitrile butadiene Styrene copolymers, acrylonitrile-butadiene-styrene copolymer), PC (Polycarbonate, polycarbonate), PA (Polyamide, polyamide fiber) or POM (polyformaldehyde).

With reference to FIGS. 2, 4 and 5, the slicer further includes a magnet 5 embedded in the base 11.
