Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pathological trimming folder. [0002] In the process of preparing a pathological tissue specimen, there are steps of cutting out, embedding, slicing, staining and enclosing, and a pathological trimming folder is used in the cutting out step. . [0003] The cutting step is a step of cutting an organ immersed in a fixative such as formalin into an appropriate size when preparing a pathological tissue specimen. In this case, a blade with a narrow blade width is used. Conventionally, used microtome replacement blades used in the slicing process have been reused in the cutting process. [0004] The used microtome replacement blade folder has a structure in which the blade is sandwiched so that the blade does not move left and right, or a structure in which the blade is slid into a slide groove having a gripping force and mounted. Some are known (for example, see Non-Patent Document 1). However, when a large organ is cut out, there is a problem that a load of the blade is applied to the folder and the blade comes out of the folder or the blade moves upward. [Non-patent Document 1] Feather Safety Razor Co., Ltd., Feather Medical Product Catalog, No. 3. Replaceable blade type trimming knife handle [0007] The present invention has been made to solve the problems described in the prior art.
An object of the present invention is to provide a pathological trimming folder in which a blade does not come out or move left, right, up and down even when a large organ is cut out. [0008] The pathological trimming folder of the present invention has a tapered taper portion at the tip which is slightly wider than the blade width of a microtome spare blade having a spare blade hole. A main body having a projection at a bottom portion of the vertical groove, the projection being fitted to a replacement blade punching hole of the microtome replacement blade, and a hole fitting to the projection at an inner surface of the main body. A substantially semi-cylindrical fastening piece that can be fitted to the tapered portion, the tapered portion of the main body and the fastening piece that is fitted into the vertical groove, and the fastening piece is pushed into the vertical groove. And a cylindrical tightening cap for preventing detachment from the vertical groove. An embodiment of the present invention will be described with reference to the drawings. As shown in FIG.
Is provided with a vertical groove 4 having a width W slightly larger than the blade width w of the microtome replacement blade 3 having the replacement hole 3 in the tapered taper portion 1 at the tip. A projection 5 is provided to be fitted in the spare blade hole 2 of the microtome spare blade 3. Accordingly, when one end of the microtome spare blade 3 is brought into contact with the rear end of the bottom a of the longitudinal groove 4 and the microtome spare blade 3 is mounted on the longitudinal groove 4, the microtome spare blade 3 The blade replacement hole 2 fits into the projection 5 so that the forward and backward movement is restricted. As shown in FIG. 3, the fastening piece B having a substantially semi-cylindrical shape is provided with a hole 6 on the inner surface b for fitting into the projection 5 at the bottom a of the vertical groove 4 so as to be fitted into the vertical groove 4. Have been. Therefore, the microtome replacement blade 3 is
Then, when the fastening piece B is fitted into the vertical groove 4, the hole 6 of the fastening piece B is fitted to the projection 5 on the bottom a of the vertical groove 4. In this state, the fastening piece B is not completely restrained from separating from the vertical groove 4. The tightening cap C is formed in a cylindrical shape as shown in FIG. 4, and as shown in FIG.
When it is mounted on the fastening piece B fitted in the pallet 1 and the vertical groove 4, the fastening piece B is pushed into the vertical groove 4, and the fastening piece B is configured to be prevented from detaching from the vertical groove 4. I have. Therefore, as shown in FIG. 5, the cover is attached to the main body A by covering the tightening cap C,
The front, rear, left, right, up and down movements of the microtome replacement blade 3 pressed by the fastening piece B are restricted. The materials of the main body A and the tightening pieces B are not particularly limited.
A plastic resin such as EVA, which is easy to process and has corrosion resistance and strength, is suitable, but hard wood such as oak or a light aluminum alloy can also be used. Also, the material of the tightening cap C is not particularly limited.
Galvanized iron or the like can be applied. At the time of implementation, the protrusions 5 of the longitudinal grooves 3 of the main body A are used.
Then, the spare blade removal hole 2 of the used microtome spare blade 3 is fitted, and the used microtome spare blade 3 is mounted in the vertical groove 3. The width W of the vertical groove 3 is designed to be wider than the blade width w of the microtome spare blade 3 by about 0.5 to 1 mm. Next, the hole 6 of the tightening piece B is fitted into the projection 5 of the longitudinal groove 3 of the main body A projecting from the spare blade hole 2 of the microtome spare blade 3, so that the tightening piece B is attached to the main body A. Into the vertical groove 3. Next, the tightening cap C is tightly inserted on the taper portion 1 of the main body A and the tightening piece B fitted into the vertical groove 4, and the work of attaching the microtome replacement blade 3 to the main body A is performed. Ends. To remove the microtome spare blade 3, the above procedure may be reversed. As a decoration, the rear end of the main body A may be finished in a polygonal shape, or a non-slip cut or the like may be provided in the middle part. For easy mounting, tightening cap C
It is free to apply a non-slip notch or the like to the rear end. Since the present invention is configured as described above, it has the following effects. The movement of the microtome spare blade in the up, down, left, right, front and back directions is restricted.
Even if a load is applied to the blade, it is possible to prevent the blade from moving back and forth from the folder and moving up and down or left and right. Microtome replacement blade can be easily attached and detached. Since the structure is simple, mass production can be performed at low cost.
