Description

A demoulding mechanism for paraffin-embedded pathological tissue wax block

Technical Field

The utility model relates to a demoulding mechanism for paraffin-embedded pathological tissue wax blocks.

Background technique

In the routine work of the pathology department, the process of supporting tissue with an embedding agent is called embedding, and routine sectioning uses paraffin embedding. The specific operation process is to inject the heated and melted paraffin into the embedding mold, then place the pathological tissue in the embedding mold, and use embedding forceps to press the pathological tissue to the bottom of the embedding mold, and then cover the embedding box. At this time, the liquid paraffin wraps the pathological tissue and isolates it from the air. When the liquid paraffin cools and solidifies into a solid state, the pathological tissue is embedded in the paraffin, and the paraffin fuses the pathological tissue with the embedding box to form a pathological tissue wax block. After the embedding is completed, the pathological tissue wax block needs to be peeled off from the embedding mold. In the process of demolding, since there are currently no professional tools, it is usually only possible to break it hard by hand, or use a hard sharp tool to pry open the gap between the pathological tissue wax block and the mold to demold it. The current demolding method is easy to damage the pathological tissue wax block due to uneven force, and the operator is also at risk of being stabbed by a sharp object.

The Chinese utility model patent announcement number is CN210604118U, and the name is a patent for a cell tissue paraffin embedding device. When the paraffin liquid solidifies, the mold shell is pressed down and the positioning device is disengaged. When the mold shell slides to the bottom plate position, the positioning device slides to the bottom end of the limit slide groove, and the positioning device is locked again, so that the mold shell is fixed relative to the mold core, and the upper end surface of the mold shell is flush with the top surface of the mold core, and the wax block can be completely demolded. Although the embedding device can realize the demolding function, it cannot be adapted to conventional embedding molds and embedding boxes. If the embedding device in the patent completely replaces conventional embedding molds and embedding boxes, it will require a lot of cost.

It is necessary to design a demoulding mechanism that is adaptable to conventional embedding molds and embedding cassettes and has low investment cost.

Pressing the transmission assembly downward can drive the first clamping rod 220 and the second clamping rod 240 to move outward, and lifting the transmission assembly can drive the first clamping rod 220 and the second clamping rod 240 to move inward to clamp the pathological tissue wax block 30 and can drive the clamping assembly and the pathological tissue wax block 30 to move upward synchronously.

In this embodiment, the transmission assembly includes a vertical rod 310, a first hinged rod 320 and a second hinged rod 330.

The use process of the demoulding mechanism is as follows:

First, the embedding mold 10 with the pathological tissue wax block 30 is placed on the table, and then the shell 100 is mounted on the top of the embedding mold 10, that is, the front and rear sides of the shell 100 are mounted on the top of the embedding mold 10, and the left and right sides of the shell 100 are suspended; because the vertical rod 310 is retractable, during the process of mounting the shell 100 on the top of the embedding mold 10, the first clamping plate 210 and the second clamping plate 230 are pressed against the top surface of the pathological tissue wax block 30, and the vertical rod 310 is driven to move upward; then, the handheld part 340 is pressed downward, and at this time, the pathological tissue wax block 30 gives the first clamping plate 210 and the second clamping plate 230 a reverse The supporting force makes the first clamping plate 210 and the second clamping plate 230 unable to move downward, but move to the left and right sides respectively, until the first clamping plate 210 and the second clamping plate 230 are respectively located outside the left and right sides of the pathological tissue wax block 30. At this time, the first clamping plate 210 and the second clamping plate 230 lose the supporting force and move downward along the left and right sides of the pathological tissue wax block 30 for a distance respectively until they are against the top of the embedding mold 10; at this time, the clamping elastic member 200 pulls the first clamping plate 210 and the second clamping plate 230 inward, so that the first clamping plate 210 and the second clamping plate 230 can be clamped on both sides of the pathological tissue wax block 30 respectively. Then, release the hand-held part 340, and move the hand-held part 340 upward under the action of the resetting elastic member 350, so that the first clamping plate 210 and the second clamping plate 230 are clamped on the left and right sides of the pathological tissue wax block 30; then, gently pull the hand-held part 340 upward, while continuing to clamp the pathological tissue wax block 30, it can also drive the pathological tissue wax block 30 upward until the pathological tissue wax block 30 is removed from the embedding mold 10, and the demoulding is completed. Since the force required for demoulding does not need to be particularly large, otherwise the pathological tissue wax block 30 will be damaged, therefore, the force applied during the entire demoulding process is relatively gentle, and the pathological tissue wax block 30 can be clamped.

Please refer to Figures 11 and 12, which are a second preferred embodiment of a demoulding mechanism for paraffin-embedded pathological tissue wax blocks. The difference between this embodiment and the first embodiment is that:

In this embodiment, the demolding mechanism is not provided with a reset elastic member 350. When the shell 100 is placed on the top of the embedding mold 10, the first clamping plate 210 and the second clamping plate 230 will be pressed against the top surface of the pathological tissue wax block 30 under the action of their own gravity, and then the hand-held part 340 is pressed downward. The pathological tissue wax block 30 will give the first clamping plate 210 and the second clamping plate 230 a reverse supporting force, so that the first clamping plate 210 and the second clamping plate 230 cannot move downward, but move to the left and right sides respectively, until the first clamping plate 210 and the second clamping plate 230 are respectively located outside the left and right sides of the pathological tissue wax block 30.

In this embodiment, in order to reduce the friction between the first clamping plate 210 and the second clamping plate 230 and the top surface of the pathological tissue wax block 30, the bottom surfaces of the first clamping plate 210 and the second clamping plate 230 can be set as inclined surfaces. At this time, there is only line contact between the bottom surfaces of the first clamping plate 210 and the second clamping plate 230 and the top surface of the pathological tissue wax block 30, and the friction is reduced.

Please refer to Figures 13 and 14, which are a third preferred embodiment of a demoulding mechanism for paraffin-embedded pathological tissue wax blocks. The difference between this embodiment and the second embodiment is that:

In this embodiment, the shell 100 is not provided. In actual use, the first clamping rod 220 and the second clamping rod 240 only need to be opened outward by hand, and clamped on the left and right sides of the pathological tissue wax block 30 respectively, and then the hand-held part 340 is lifted upward to remove the pathological tissue wax block 30 from the embedding mold 10 to complete the demolding.

The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the content of the specification should still fall within the scope covered by the present invention.
