Description

Demoulding mechanism for paraffin embedded pathological tissue wax block

Technical Field

The utility model relates to a demolding mechanism for paraffin embedding pathological tissue wax blocks.

Background

In the routine work of the pathology department, the process of supporting tissue with an embedding agent is called embedding, and paraffin embedding is used for conventional sections. The specific operation process is that paraffin melted into liquid state by heating is injected into an embedding mould, pathological tissues are placed in the embedding mould, the pathological tissues are pressed to the bottom of the embedding mould by using embedding forceps, and then an embedding box is covered, and at the moment, the pathological tissues are wrapped by the liquid paraffin and isolated from air. When the liquid paraffin is cooled and solidified into a solid state, the pathological tissue is embedded in the paraffin, and the paraffin fuses the pathological tissue and the embedding box together to form a pathological tissue wax block. After embedding, the pathological tissue wax block needs to be stripped from the embedding mould. In the demolding process, no special tool exists at present, so that the pathological tissue wax block can be broken off by hand or the gap between the pathological tissue wax block and the mold can be pried off by means of a hard sharp tool, and the demolding is performed. The existing demolding method is uneven in stress, so that pathological tissue wax blocks are easy to damage, and operators are also at risk of being stabbed by sharp instruments.

In the patent with the Chinese patent publication number of CN210604118U and the name of a cell tissue paraffin embedding device, after paraffin liquid is solidified, a die shell is pressed downwards, a positioning device is separated from positioning, when the die shell slides to a bottom plate position, the positioning device slides to the bottom end of a limiting chute, the positioning device is locked again, the die shell is fixed relative to a die core, the upper end face of the die shell is flush with the top face of the die core, and a paraffin block can be completely demoulded. Although the embedding device can realize the demolding function, the embedding device cannot be matched with a conventional embedding mold and an embedding box, and if the embedding device in the patent is used for completely replacing the conventional embedding mold and the conventional embedding box, great cost is required to be input.

It is necessary to design a stripping mechanism which is adaptable to conventional embedding dies and boxes and has low investment cost.

The demolding mechanism has the following use process:

Firstly, placing an embedding mould 10 with a pathological tissue wax 30 on a table top, then, placing a shell 100 on the top end of the embedding mould 10, namely, placing the front side surface and the rear side surface of the shell 100 on the top end of the embedding mould 10, wherein the left side surface and the right side surface of the shell 100 are in a suspended state; because the vertical rod 310 has elasticity, in the process of setting the housing 100 at the top end of the embedding mold 10, the first clamping plate 210 and the second clamping plate 230 press against the top surface of the pathological tissue wax 30 and simultaneously drive the vertical rod 310 to move upwards; then, the hand-hold portion 340 is pressed downwards, at this time, the pathological tissue wax 30 will give a reverse supporting force to the first clamping plate 210 and the second clamping plate 230, so that the first clamping plate 210 and the second clamping plate 230 cannot move downwards, but move leftwards and rightwards respectively, until the first clamping plate 210 and the second clamping plate 230 are located outside the left side and the right side of the pathological tissue wax 30 respectively, at this time, the first clamping plate 210 and the second clamping plate 230 lose the supporting force and move downwards for a certain distance along the left side surface and the right side surface of the pathological tissue wax 30 respectively until abutting against the top end 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 respectively clamp both sides of the pathological tissue wax 30. Then, the hand-holding part 340 is released, and the hand-holding part 340 moves upward under the action of the return elastic member 350, so that the first clamping plate 210 and the second clamping plate 230 are clamped at the left and right sides of the pathological tissue wax 30; then, the handle 340 is lifted slightly upwards, and the pathological tissue wax 30 can be driven upwards while continuously clamping the pathological tissue wax 30 until the pathological tissue wax 30 is released from the embedding mould 10, so that demoulding is completed. Because the force required for demolding is not particularly large, otherwise damage to the pathological tissue wax 30 is caused, the force applied in the whole demolding process is softer, so that the pathological tissue wax 30 can be clamped.

Referring to fig. 11-12, a second preferred embodiment of a demolding mechanism for paraffin embedding pathological tissue wax blocks is shown. This embodiment differs from the first embodiment in that:

In this embodiment, the demolding mechanism is not provided with the reset elastic member 350, when the housing 100 is mounted on the top end 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 30 under the action of self gravity, and then the hand-holding portion 340 is pressed downward, so that the pathological tissue wax 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 located outside the left and right sides of the pathological tissue wax 30 respectively.

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 30, the bottom surfaces of the first clamping plate 210 and the second clamping plate 230 may be inclined surfaces, and at this time, only the line-surface contact is made 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 30, so that the friction is reduced.

Referring to fig. 13-14, a third preferred embodiment of a demolding mechanism for paraffin embedding pathological tissue wax blocks is shown. The present embodiment differs from the second embodiment in that:

In this embodiment, the housing 100 is not provided, and in actual use, the first clamping rod 220 and the second clamping rod 240 are only required to be manually separated outwards and respectively clamped on the left side surface and the right side surface of the pathological tissue wax 30, and then the handheld portion 340 is lifted upwards, so that the pathological tissue wax 30 can be removed from the embedding mold 10, and demolding is completed.

The foregoing description is only illustrative of the preferred embodiments of the present utility model, and therefore should not be taken as limiting the scope of the utility model, for all changes and modifications that come within the meaning and range of equivalency of the claims and specification are therefore intended to be embraced therein.
