[0002] An embedding box is a tool for embedding material powder or other block structures to provide performance support or chemical protection. The embedding box is a medical consumable used in the entire process of tissue section preparation, including dehydration, wax immersion and embedding, and is widely used.

[0003] The existing embedding box is of an upward opening type. When operating, the cover body is quickly popped open by pressing the buckle part with fingers. When processing a large number of samples, the operator often uses a quick cover opening action to improve efficiency. At this time, the cover body and the box body are instantaneously separated, which can generate significant airflow disturbance. For light quality dehydrated tissues (such as breast adipose tissue, lung tissue, etc.), it is easy to move away from the box body with the airflow, which can contaminate the tissues or cause sample loss. At the same time, when processing hundreds of samples in batches, one hand is fixed and the other hand is used to flip the cover, which significantly aggravates the hand fatigue of the operator.

DETAILED DESCRIPTION

[0023] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions will be described below in connection with the accompanying drawings in the present application. Obviously, the described embodiments are only a part instead of all of the embodiments of the present application. Based upon the embodiments in the present application, all the other embodiments obtained by those ordinarily skilled in the art without creative work fall into the scope of protection of the present application.

[0024] The present application discloses a pathological tissue embedding box with a sliding cover. Referring to Figure 1 and Figure 2 The pathological tissue embedding box with a sliding cover comprises a box body 1 with an open top and a cover body 2 with a sliding cover arranged on the top opening end of the box body 1. One end of the side wall of the box body 1 is provided as a slope surface, and the slope surface is engraved with an encoding for quick identification by experimenters. The inner walls on both sides of the box body 1 are provided with sliding grooves 10 distributed along the length direction thereof, and the side walls of the cover body 2 are fixed with sliding blocks 11, which are slidingly arranged in the sliding grooves 10, so that the cover body 2 can stably slide on the top of the box body 1 to realize the opening and closing of the embedding box. The top of one end of the box body 1 is horizontally provided with a baffle 3, which is arranged close to the slope surface on the box body 1. The lower surface of the baffle 3 is coated with a Teflon coating, which not only has good corrosion resistance, but also can protect the lower surface of the baffle 3 from being easily scratched. When the cover body 2 slides against the side edge of the baffle 3, the top opening end of the box body 1 is covered and shielded by the cover body 2 and the baffle 3, so that the pathological tissue is properly stored in the embedding box. A plurality of grid holes 12 are formed on the box body 1 and the cover body 2, so that when the pathological tissue stored in the embedding box is subjected to dehydration treatment, the dehydration reagent can smoothly enter the embedding box.

[0025] In order to prevent the pathological tissue from being easily taken out of the embedding box, referring to Figure 1 and Figure 2The locking assembly 4 is arranged between the cover 2 and the baffle 3 for locking and abutting the cover 2 on the side edge of the baffle 3. In the embodiment, a notch 5 is formed in the middle of the side edge of the cover 2 close to the baffle 3, the locking assembly 4 comprises a rotating shaft 41 fixed in the notch 5, a rotating pin 42 rotatably arranged on the cover 2 through the rotating shaft 41, a protrusion 43 fixed on the top surface of the rotating pin 42, and a torsion spring 44 sleeved on the rotating shaft 41; one end of the torsion spring 44 is fixedly connected with the rotating shaft 41, and the other end is fixedly connected with the rotating pin 42; in the natural state, the torsion spring 44 drives the rotating pin 42 to tilt away from the box body 1; when the rotating pin 42 is rotated to a position parallel to the cover 2, the rotating pin 42 is located below the baffle 3, but the top of the protrusion 43 on the rotating pin 42 is higher than the lower surface of the baffle 3. A clamping hole 6 is formed through the baffle 3 for inserting the protrusion 43, and the width dimension of the clamping hole 6 along the sliding direction of the cover 2 is greater than the thickness dimension of the protrusion 43 along the sliding direction of the cover 2, so that when the cover 2 is abutted against the baffle 3, the torsion spring 44 drives the rotating pin 42 to rotate and stably insert the protrusion 43 into the clamping hole 6, and the cover 2 and the baffle 3 stably cover the opening at the top of the box body 1.

[0026] To ensure that the protrusion 43 can be smoothly rotated and inserted into the clamping hole 6, and also can be rotated out of the clamping hole 6, referring to Figure 1 and Figure 2 , the side close to the baffle 3 of the protrusion 43 is provided with an inclined guide surface 7. When closing the embedding box, only need to push the cover 2 to slide towards the baffle 3, when the inclined guide surface 7 on the protrusion 43 abuts against the side edge of the baffle 3, the rotating pin 42 is pushed to rotate into the box body 1, until the cover 2 abuts against the baffle 3, under the action of the torsion spring 44, the rotating pin 42 drives the protrusion 43 to rotate and insert into the clamping hole 6. When opening the embedding box, only need to rotate the rotating pin 42 towards the inside of the box body 1, so that the protrusion 43 moves out of the clamping hole 6, and then move the cover 2 away from the baffle 3, the embedding box can be opened.

[0027] To make the protrusion 43 quickly move out of the clamping hole 6, so as to quickly open the embedding box, referring to Figure 1 and Figure 2 , the top surface of the rotating pin 42 is provided with a pushing block 8 for driving the rotating pin 42 to rotate, the pushing block 8 is located on the side of the rotating shaft 41 close to the protrusion 43, and the pushing block 8 is inclinedly arranged on the rotating pin 42 towards the protrusion 43. By pressing the pushing block 8 towards the inside of the box body 1, the rotating pin 42 can drive the protrusion 43 to rotate to the inside of the box body 1, so that the protrusion 43 can quickly move out of the clamping hole 6, thereby quickly sliding the cover 2 to open the embedding box.

[0028] When the finger presses the rotating pin 42 during the process of sliding the cover 2 to open, the rotating pin 42 can drive the cover 2 to slide towards the direction away from the baffle 3. When the rotating pin 42 is pressed, the pressing block 8 on the rotating pin 42 will abut against the edge of the gap 5. In order to avoid the pressing block 8 being damaged, the surface of the pressing block 8 away from the protrusion 43 is provided with an elastic gasket 9. Considering that the embedding box needs to be put into the dehydrating reagent for soaking, and the main components of the dehydrating reagent are ethanol and dimethylbenzene, in order to avoid the elastic gasket 9 being corroded, the material of the elastic gasket 9 can be perfluoroether rubber, polyether ether ketone, modified polyurethane, etc.

[0029] The implementation principle of the pathological tissue embedding box with a sliding cover according to the embodiment of the application is as follows: the pathological tissue is put into the box body 1 and the cover 2 is slid towards the direction of the baffle 3. When the inclined guide surface 7 on the protrusion 43 abuts against the side edge of the baffle 3, the rotating pin 42 is pushed to rotate into the box body 1 until the cover 2 abuts against the baffle 3. Under the action of the torsion spring 44, the rotating pin 42 drives the protrusion 43 to rotate and insert into the clamping hole 6. At this time, the top opening end of the box body 1 is covered and shielded by the cover 2 and the baffle 3, and the pathological tissue is properly stored in the embedding box. After the dehydration treatment of the pathological tissue is completed, the pressing block 8 can be pressed towards the direction of the box body 1, so that the rotating pin 42 can drive the protrusion 43 to rotate towards the inside of the box body 1, and then the protrusion 43 can be quickly removed from the clamping hole 6. Then, the finger can press the rotating pin 42, so that the rotating pin 42 can drive the cover 2 to slide towards the direction away from the baffle 3, and the embedding box can be opened to take out the pathological tissue.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the application, but not to limit the application; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the application.
