[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] See also Figures 1 to 5 The human pericardium shaping and soaking device in the utility model comprises a soaking box 10, a lifting assembly and a carrier plate 21, wherein the carrier plate 21 is arranged in the soaking box 10 through the lifting assembly;

[0030] The carrier plate 21 is provided with a plurality of first through holes 22;

[0031] The lifting assembly includes a support seat 31, a movable connecting rod structure, a connecting block 33 and a rotating shaft 32. The support seat 31 is fixedly arranged on the bottom surface of the inner cavity of the soaking box 10. The rotating shaft 32 is rotatably connected to the support seat 31, and one end of the rotating shaft 32 passes through the outside of the soaking box 10. The connecting block 33 is arranged at the bottom of the carrier plate 21. The movable connecting rod structure connects the connecting block 33 and the rotating shaft 32. When the rotating shaft 32 rotates, the movable connecting rod structure applies an upward force to the connecting block 33, thereby driving the carrier plate 21 to rise.

[0032] By rotating the rotating shaft 32 outside the soaking box 10, the carrier plate 21 is quickly lifted above the soaking liquid surface under the action of the movable connecting rod structure, so that medical staff can take the pericardium, which effectively improves work efficiency. In addition, the support seat 31 on the bottom surface of the inner cavity of the soaking box 10 can also provide a certain support for the carrier plate 21, so that the soaking liquid can pass through the first through hole 22, thereby fully soaking the pericardium and the carrier plate 21.

[0033] like Figure 4 As shown, the movable connecting rod structure includes a first driving rod 34 and a second driving rod 35, one end of the first driving rod 34 is fixedly connected to the rotating shaft 32, and the other end is rotatably connected to one end of the second driving rod 35 through a first pin shaft 41, and the end of the second driving rod 35 away from the first driving rod 34 is rotatably connected to the connecting block 33 through a second pin shaft 42.

[0034] In actual application, when the rotating shaft 32 rotates counterclockwise, the first driving rod 34 fixed thereto will also swing accordingly, and the second driving rod 35 will gradually unfold under the action of the first driving rod 34, and drive the connecting block 33 to rise, thereby realizing the lifting of the entire carrier 21. Conversely, if the carrier 21 needs to be reset, it is only necessary to loosen the rotating shaft 32, and the carrier 21 will automatically sink to the bottom surface of the inner cavity of the immersion box 10 under the action of gravity, and the first driving rod 34 and the second driving rod 35 will return to the folded state.

[0035] Specifically, in the present embodiment, there are two groups of movable link structures, which are located at the left and right ends of the rotating shaft 32 , in order to provide a stable lifting force for the carrier plate 21 .

[0036] Further, combined with Figure 4 and Figure 5 As shown, the left and right sides of the carrier plate 21 are respectively fixed with fixed side plates 51, and the two fixed side plates 51 are respectively provided with guide sleeves 52, and the inner cavity bottom surface of the soaking box 10 is provided with a guide rod 53 that is slidably connected with the guide sleeve 52. It can be understood that when the second driving rod 35 pushes the carrier plate 21 to move, the sliding cooperation between the guide sleeve 52 and the guide rod 53 can make the carrier plate 21 move up and down smoothly along the vertical direction, so as to avoid the position of the carrier plate 21 from shifting during the movement. Specifically, in this embodiment, there are 4 guide sleeves 52, and the 4 guide sleeves 52 are symmetrically distributed on the fixed side plates 51 in pairs. The number of guide sleeves 52 can be adaptively adjusted according to needs, and can also be two, etc. This embodiment is only an example and not a limitation.

[0037] Furthermore, movable side plates 61 are respectively provided on the front and rear sides of the carrier plate 21, and the movable side plates 61 are rotatably connected between the two fixed side plates 51 through a third pin shaft 62. A limit stop block 63 is provided on the inner side surface of the fixed side plate 51, and a wedge-shaped reset block 64 is provided on the inner wall of the immersion box 10. When the carrier plate 21 is sunk into the immersion box 10, the movable side plate 61 is limited between the limit stop block 63 and the wedge-shaped reset block 64.

[0038] For details, see Figure 5, the wedge-shaped reset block 64 is provided with a vertical plane 641 and an inclined surface 642 on one side facing the movable side plate 61, and the vertical plane 641 and the inclined surface 642 are arranged in sequence from bottom to top. It can be understood that when the carrier 21 sinks to the bottom of the soaking box 10, the movable side plate 61 is limited between the limit stopper 63 and the vertical plane 641 of the wedge-shaped reset block 64; and when the carrier 21 is lifted to a position higher than the vertical plane 641, the movable side plate 61 is no longer restricted, and the two movable side plates 61 can be relatively unfolded and finally abut against the inclined surface 642 of the wedge-shaped reset block 64. When the movable side plate 61 is unfolded, it is convenient for medical staff to remove the pericardium from the carrier 21, avoiding the inconvenience of taking due to structural limitations.

[0039] For further information, see Figure 3 When the movable side plate 61 stops against the limit stopper 63, the two movable side plates 61 are tilted at a certain angle in a direction away from each other. Specifically, the offset angle of the movable side plate 61 relative to the vertical line of the carrier plate 21 is 5 to 10 degrees. This design enables the movable side plate 61 to automatically unfold under the action of gravity when the carrier plate 21 is lifted to a certain height; conversely, when the carrier plate 21 moves downward, the movable side plate 61 can automatically return to its original position under the resistance of the inclined surface 642 of the wedge-shaped reset plate until the movable side plate 61 contacts the limit stopper 63, thereby achieving closure around the carrier plate 21 so as to limit the pericardium.

[0040] For further information, see Figure 4 , the fixed side plate 51 and the movable side plate 61 are both provided with a plurality of second through holes 70. It can be understood that when the carrier plate 21 sinks to the bottom of the soaking box 10, the soaking liquid can not only penetrate into the fitting surface of the carrier plate 21 and the pericardium through the first through holes 22, but also penetrate through the second through holes 70, so that the soaking liquid can completely cover the pericardium, so that it can be in full contact with the soaking liquid, and the pericardium can be soaked and shaped.

[0041] For further information, see Figure 2 A turntable 81 is fixedly provided at one end of the rotating shaft 32 outside the soaking box 10, and a clamping rod 82 is inserted into the turntable 81. A clamping groove 83 is provided on the outer wall of the soaking box 10, and the clamping groove 83 is used to cooperate with the clamping rod 82 to limit the rotation angle of the rotating shaft 32.

[0042] In actual application, the user can operate the turntable 81 to drive the shaft 32 to rotate. When the shaft 32 rotates counterclockwise to the extreme position, the clamping rod 82 corresponds to the clamping slot 83. By inserting the clamping rod 82 into the clamping slot 83, the shaft 32 can be limited. Therefore, the carrier plate 21 is fixed in a raised state and will not sink, which makes it convenient for medical staff to remove the pericardium on the carrier plate 21.

[0043] Further, such as Figure 1 As shown, a sealing cover 91 is hinged on the top of the soaking box 10, and a sealing ring 92 is provided on one side of the sealing cover 91 that is in contact with the soaking box 10. The sealing cover 91 can seal the opening of the soaking box 10 when the pericardium is soaked, so as to prevent contaminants from falling into the soaking box during the soaking process and causing contamination of the pericardium.

[0044] Working principle: The pericardium is placed in the soaking box 10 for soaking and shaping. After the soaking is completed, the turntable 81 is rotated counterclockwise so that the rotating shaft 32 drives the first driving rod 34 fixed thereto to rotate, and the first driving rod 34 drives the second driving rod 35 to act on the connecting block 33, thereby pushing the carrier plate 21 to move upward until the pericardium is exposed to the liquid surface. At this time, the movable side plate 61 can be resting on the inclined surface 642 of the wedge-shaped reset plate under the action of gravity, thereby opening the two sides of the carrier plate 21 to expand the opening area of ​​the carrier plate 21, and finally the clamping rod 82 is inserted into the clamping slot 83 to fix the position of the carrier plate 21 so that medical staff can take the pericardium.

[0045] In summary, the human pericardium shaping soaking device in the above-mentioned embodiment of the utility model, by rotating the rotating shaft 32 outside the soaking box 10, under the action of the movable connecting rod structure, the carrier plate 21 is quickly lifted to above the soaking liquid surface, so that medical staff can take the pericardium, which effectively improves the work efficiency. In addition, the support seat 31 on the bottom surface of the inner cavity of the soaking box 10 can also provide a certain support for the carrier plate 21, so that the soaking liquid can pass through the first through hole 22, thereby fully soaking the side of the pericardium that is in contact with the carrier plate 21.
