Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
In the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
As shown in fig. 1-6, the present embodiment discloses a tissue specimen fixing device, which mainly includes a bottom case 1 and a cover 2, the bottom case 1 and the cover 2 are vertically matched to fix a tissue specimen, and the bottom case 1 and the cover 2 are respectively made of disposable transparent medical plastics integrally. For ease of transportation and handling, the base 1 and lid 2 are each of disc-shaped configuration. The central position of lid 2 installs circular shape central apron 3 with the mode of pegging graft, and the diameter of central apron 3 is half of the lid 2 diameter, has seted up the round hole 4 that can place protruding tissue (like the tumour) in the central position of central apron 3. By the design, the central cover plate 3 with different specifications and sizes of the round holes 4 can be selected to be inserted on the cover body 2 according to the tumor size of the tissue specimen.
The surfaces of the bottom shell 1 and the cover body 2 are provided with a plurality of holes allowing the solution to pass through, the holes processed on the surface of the cover body 2 (including the central cover plate 3) are strip-shaped holes 5, and all the strip-shaped holes 5 are radially distributed by taking the round hole 4 as the center. The inner side surfaces of the bottom shell 1 and the cover body 2 are respectively provided with a plurality of densely distributed fixed bulges 6 with the height of 2mm, and the top ends of the fixed bulges are arc-shaped. So design, when tissue specimen places between lid 2 and drain pan 1, make tissue specimen can not laminate on the surface of drain pan 1 and lid 2, guarantee that tissue specimen fully contacts the stationary liquid.
The edge processing of lid 2 has three evenly distributed's joint leg 7, and the lower extreme inboard of every joint leg 7 is equipped with joint barb 8. When butt joint cooperation about lid 2 and drain pan 1, the marginal processing of drain pan 1 has the concave point group that can with joint barb 8 one-to-one joint. Every nook group includes nook A9 and is located nook B10 of nook A9 below places back on drain pan 1 as tissue specimen, aligns down the installation with lid 2 from the top, when the 8 joints of joint barb are on nook A9, realizes lid 2 and drain pan 1 to the pre-fixing of tissue specimen, and tissue specimen spreads to be in the flattening state this moment, and the operator can wear long strip hole 5 to stir tissue specimen with the plastic rod. When the clamping barb 8 is clamped at the concave point B10, the tissue specimen is completely fixed.
The bottom of the bottom shell 1 is provided with grid lines 11, and the unit grids of the grid lines 11 are all grids with the side length of 1 cm. Because the tissue specimen is made of transparent material, the area of the tissue specimen can be estimated by the grid lines 11. 12 position indicators 12 are arranged on the upper surface of the cover body 2, and the 12 position indicators 12 are annularly distributed by taking the center of the cover body 2 as the center of a circle.
