Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific embodiments. The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.

[0022] Such as Figure 1 to Figure 7 A biomedical tissue slicer shown includes a bottom plate 1, a top plate 2, a side plate 3 and a cover plate 4, and involves a spacing adjustment module and a piezoelectric ceramic driving cutting module, wherein:

[0023] The spacing adjustment module also includes a translation frame 7, a ceramic sheet mounting plate 11, and a retaining ring 701. Several groups of ceramic sheet mounting plates 11 are slidably installed in the track of the side plate 3 through their two trunnions. A retaining ring 701 is also installed on the shaft protruding from the trunnion section of the side plate 3, and the translation frame 7 is fixedly installed on the outermost end of the trunnion of the...

Abstract

The invention discloses a biomedical microtome. The biomedical microtome comprises a piezoelectric ceramic cutting group, a manual space indexing group and a mechanism adjusting group. The biomedicalmicrotome has the advantages that a novel piezoelectric ceramic micro-motion drive is applied, and the characteristic of small action quantity and high frequency response are utilized for small-action-quantity micro-motion cutting, so that pulling and tearing of tissues are reduced, and smoothness and observability of end surfaces of tissue cells can be maintained as much as possible; a blade space adjustment structure is individually adjustable, and the tissues with different thicknesses can be sectioned; the biomedical microtome has a simple structure, clear actions and a good execution effect.

Description

technical field [0001] The invention provides a biomedical tissue slicer, which belongs to the design field of medical tissue slicers in medical instruments. Background technique [0002] Medical tissue slicer is used in clinical medicine, inspection and quarantine. Case analysis and other fields have a very high application. The current slicing technology has a large strain and tear on the tissue, and the formed tissue slice is incomplete; and the operation efficiency is low, and most of them are operated by shaking the hand wheel. In order to achieve a more complete slice of medical tissue, while improving the simplification of operation and the lightweight and miniaturization of equipment, it is more urgent to design a new medical tissue slicer. Contents of the invention [0003] Aiming at the above-mentioned present situation, the present invention provides a biomedical tissue slicer, which is characterized in that a new type of piezoelectric ceramic is used for driv...
