Description

Pathological tissue blade taking-out structure

Technical Field

The utility model relates to the technical field of medical examination equipment, in particular to a pathological tissue blade taking-out structure.

Background

Pathological tissue section refers to a mode of taking pathological tissue with a certain size and then preparing pathological section by using a pathological histology method. In general, pathological tissue sections are obtained by subjecting pathological tissues or organs to various chemicals and embedding methods to fix and harden the pathological tissues or organs, then slicing the pathological tissues or organs on a microtome, adhering the slice on a slide, and staining the slice with various colors for examination under a microscope to observe pathological changes, thereby making pathological diagnoses and providing assistance for clinical diagnosis and treatment.

In preparing pathological tissue slices, it is necessary to prepare pathological tissue slices by using a single-use pathological tissue blade by a microtome, and therefore, the amount of single-use pathological tissue blade used is very large. For convenient transportation, storage and use, a plurality of disposable pathological tissue blades are usually packaged and stored in a blade box during production, and the blades are sequentially taken out and installed in a slicing machine during use.

The prior art has disclosed a variety of blade cartridges for storing disposable pathological tissue blades, such as the applicant's earlier filed patent application publication number CN218490441U, which discloses a blade cartridge for storing disposable pathological tissue slice blades, said blade cartridge comprising: the box body is of a rectangular structure, and the interior of the box body is hollow and forms a space for storing the disposable pathological tissue slice blade; the cover body is opened at one side of the box body and detachably covered at the opened side of the box body, and a cavity for storing the disposable pathological tissue slice blade is formed by the box body and the cover body together; the sliding block is arranged on the box body, the sliding block is slidably inserted into the sliding groove, and can push the disposable pathological tissue slice blade in the blade box to move to one side close to the blade outlet and be discharged through the blade outlet. The structure of the blade taking-out blade in the blade box is simple and is easy to grasp by a user, but the structure of the blade taking-out blade is found in the actual use process and still has the following defects:

firstly, because the blade box is generally prepared from materials such as plastic with thinner thickness, certain elastic deformation capability exists, when a user pushes the sliding block to push out the disposable pathological tissue blades in the blade box, particularly the sliding block, the sliding groove and the blade outlet, is often deformed due to overlarge force, so that a plurality of disposable pathological tissue blades are pushed out once or cannot be pushed out, and the problems that the number of discharged blades is inaccurate and a single blade cannot be taken out accurately exist;

secondly, when the user pushes the sliding block to push out the disposable pathological tissue blade in the blade box, the sliding speed of the sliding block is overlarge due to overlarge force, so that the sliding block can quickly push the blade to be discharged outwards and drop from the blade outlet, and the problem of pollution to the disposable pathological tissue blade is caused.

In view of this, the present utility model has been made.
