By holding the biosheets in place, the first and second clamping plates are secured in a slot, separating different biosheets and preventing them from piling up. Since the first and second clamping plates are fixed in place by matching positioning rods and holes, they are less prone to relative displacement and are easily secured in the slot. Furthermore, a liquid channel is formed between the first and second support plates, allowing degreasing agent to enter and soak the first and second clamping plates.

[0031] This embodiment provides a biological sheet degreasing scaffold 10. Please refer to... Figure 1 and Figure 2 It includes a support frame 11 and a clamping assembly 12. The support frame 11 includes a first support plate 111, a second support plate 112 disposed opposite to each other, and a third support plate connected to the first support plate 111 and the second support plate 112 at both ends. The first support plate 111, the second support plate 112 and the third support plate form the support frame 11.
[0032] A liquid channel 113 is formed between the first support plate 111 and the second support plate 112. Both the first support plate 111 and the second support plate 112 are provided with a plurality of slots 114 along the height direction, and there is a certain distance between adjacent slots 114. When the support frame 11 is placed in a container filled with degreasing liquid, the degreasing agent can enter through the liquid channel 113 and soak the first clamping plate 121 and the second clamping plate 122 because the liquid channel 113 is formed between the first support plate 111 and the second support plate 112.
[0033] Please refer to Figures 4-6The clamping assembly 12 includes a first clamping plate 121 and a second clamping plate 122 for clamping the biological sheet 20; one of the first clamping plate 121 and the second clamping plate 122 has a positioning rod 123, and the other has a positioning hole 124 that matches the positioning rod 123. For example, the first clamping plate 121 may have a positioning rod 123 and the second clamping plate 122 may have a positioning hole 124; or the first clamping plate 121 may have a positioning hole 124 and the second clamping plate 122 may have a positioning rod 123.
[0034] After the first clamping plate 121 and the second clamping plate 122 clamp the biological sheet 20, they can be held in the slots 114 of the first support plate 111 and the second support plate 112. For example, the end of the slot 114 is provided with a guide surface 1141 (see reference). Figure 3 The guide surfaces 1141 are respectively connected to the upper and lower edges of the slot 114. The guide surfaces 1141 are inclined relative to the extension direction of the slot 114, and the inner diameter of the opening formed by the two guide surfaces 1141 is larger than the inner diameter of the slot 114. When the first clamping plate 121 and the second clamping plate 122 holding the biological sheet 20 are inserted into the slot 114 together, it is easier to insert the first clamping plate 121 and the second clamping plate 122 into the slot 114 together due to the guidance of the guide surfaces 1141.
[0035] The first clamping plate 121 has a first clamping surface 1213 for clamping the biological sheet 20, and the second clamping plate 122 has a second clamping surface 1224 for clamping the biological sheet 20. The first clamping plate 121 has a first liquid passage 1211 extending through the thickness direction, and the second clamping plate 122 has a second liquid passage 1221 extending through the thickness direction. The first liquid passage 1211 and the second liquid passage 1221 enable the degreasing solution to act on the biological sheet 20 to degrease it.
[0036] For example, the diameter of the first liquid passage hole 1211 gradually decreases from the side near the first clamping surface 1213 to the side away from the first clamping surface 1213; the diameter of the second liquid passage hole 1221 gradually decreases from the side near the second clamping surface 1224 to the side away from the second clamping surface 1224.
[0037] The larger diameter of the first liquid-through hole 1211 near the first clamping surface 1213 allows the biological sheet 20 to directly contact more degreasing liquid, thus facilitating degreasing. Conversely, the smaller diameter of the first liquid-through hole 1211 further away from the first clamping surface 1213 provides better support for the biological sheet 20. Similarly, the larger diameter of the second liquid-through hole 1221 near the second clamping surface 1224 allows the biological sheet 20 to directly contact more degreasing liquid, thus facilitating degreasing. Conversely, the smaller diameter of the second liquid-through hole 1221 further away from the second clamping surface 1224 provides better support for the biological sheet 20.
[0038] The biosheet degreasing support 10 of this application can clamp the biosheet 20 using a first clamping plate 121 and a second clamping plate 122. By securing the first clamping plate 121 and the second clamping plate 122, which hold the biosheet 20 in place, different biosheets 20 are separated, preventing them from piling up. Since the first clamping plate 121 and the second clamping plate 122 are fixed in place by matching positioning rods 123 and positioning holes 124, they are less prone to relative displacement, facilitating placement and securing within the slot 114. When the biosheet degreasing support 10 is placed in a degreasing solution, the solution acts on the biosheet 20 through the first liquid passage 1211 and the second liquid passage 1221, thereby degreasing the biosheet 20. The biological sheet degreasing scaffold 10 of this application clamps and fixes the biological sheet 20, preventing the biological sheet 20 from piling up, thereby improving the degreasing efficiency.
[0039] For example, the support frame 11 is connected to a handle, which allows the support frame 11 together with the clamping assembly 12 to be easily placed in the degreasing liquid.
[0040] For example, the first clamping plate 121 is frame-shaped or annular and forms a hollow area 1212. The first clamping plate 121 can clamp the edge of the biomaterial sheet 20. At least a portion of the second liquid passage holes 1221 are aligned with the hollow area 1212. That is, the second liquid passage holes 1221 can be completely aligned with the hollow area 1212, or a portion of the second liquid passage holes 1221 can be aligned with the hollow area 1212, and the remaining portion can be aligned with the first liquid passage holes 1211 provided on the first clamping plate 121. The hollow area 1212 allows one side of the biomaterial sheet 20 to have a large area that can directly contact the degreasing liquid, which is beneficial to improving the degreasing efficiency. Moreover, the second clamping plate 122 can provide support for the biomaterial sheet 20, preventing the biomaterial sheet 20 from falling off between the first clamping plate 121 and the second clamping plate 122.
[0041] Furthermore, the second clamping plate 122 includes a clamping portion 1222 and a recessed portion 1223. A positioning rod 123 or a positioning hole 124 is provided in the clamping portion 1222. The thickness of the recessed portion 1223 is less than the thickness of the clamping portion 1222. The clamping portion 1222 is able to clamp the edge of the biological sheet 20. When the clamping portion 1222 of the second clamping plate 122 and the first clamping plate 121 clamp the biological sheet 20, there is a gap between the biological sheet 20 and the recessed portion 1223.
[0042] Since the thickness of the recess 1223 is less than the thickness of the clamping portion 1222, when the clamping portion 1222 and the first clamping plate 121 jointly clamp the biosheet 20, the edge of the biosheet 20 adheres to the clamping portion 1222, and there is a gap between the biosheet 20 and the recess 1223. The degreasing liquid can then enter the recess 1223 through the second liquid passage 1221 at the location of the recess 1223 and act on the biosheet. The area of direct contact between the degreasing liquid and the biosheet 20 is larger, which is more conducive to degreasing. Moreover, although there is a gap between the recess 1223 and the biosheet 20, even if the biosheet 20 collapses downwards and contacts the recess 1223, the recess 1223 can still provide some support, preventing the biosheet 20 from falling off between the first clamping plate 121 and the second clamping plate 122.
[0043] For example, the inner diameter of the positioning hole 124 gradually decreases along the thickness direction, and the diameter of the end of the positioning hole 124 near the recess 1223 is larger than the diameter of the end of the positioning hole 124 away from the recess 1223; the inner diameter of the positioning rod 123 is equal to the diameter of the end of the positioning hole 124 away from the recess 1223. That is, when the positioning rod 123 is provided on the first clamping plate 121 and the positioning hole 124 is provided on the second clamping plate 122, the inner diameter of the positioning rod 123 is smaller than the diameter of the end of the positioning hole 124 near the recess 1223. Therefore, when the positioning rod 123 is inserted into the positioning hole 124, the end with the larger diameter of the positioning hole 124 enters first, and then the end with the smaller diameter of the positioning hole 124, which facilitates the insertion of the positioning rod 123 into the positioning hole 124 and fixes the positioning rod 123 inside the positioning hole 124.
[0044] Furthermore, to facilitate the removal of the degreased biological sheet 20 from the first clamping plate 121 and the second clamping member, exemplarily, when the first clamping plate 121 and the second clamping plate 122 clamp the biological sheet 20, the edges of the opposite ends of the first clamping plate 121 and the second clamping plate 122 are staggered. Because the edges of the first clamping plate 121 and the second clamping plate 122 are staggered, it is easy to separate the first clamping plate 121 and the second clamping plate 122, thereby removing the biological sheet 20 clamped between the first clamping plate 121 and the second clamping plate 122.
[0045] In one embodiment, the length of the first clamping plate 121 is less than the length of the second clamping plate 122. When the first clamping plate 121 and the second clamping plate 122 clamp the biological sheet 20, the edge of the second clamping plate 122 extends relative to the edge of the first clamping plate 121, and the edges of the first clamping plate 121 and the second clamping plate 122 are relatively offset, thereby facilitating the separation of the first clamping plate 121 and the second clamping plate 122.
[0046] In another embodiment, the edge of the first clamping plate 121 extends in a straight line, and the edge of the second clamping plate 122 extends in a wavy pattern. When the first clamping plate 121 with its straight edge and the second clamping plate 122 with its wavy edge overlap to clamp the biomaterial 20, there is a staggered portion between the first clamping plate 121 and the second clamping plate 122, thereby facilitating the separation of the first clamping plate 121 and the second clamping plate 122.
[0047] In summary, the biological sheet degreasing support 10 of this application can clamp the biological sheet 20 using the first clamping plate 121 and the second clamping plate 122. Then, by holding the biological sheet 20 in place, the first clamping plate 121 and the second clamping plate 122 are secured in the slot 114, separating different biological sheets 20 and preventing them from piling up. Since the first clamping plate 121 and the second clamping plate 122 are positioned and fixed by matching positioning rods 123 and positioning holes 124, they are less prone to relative displacement, facilitating placement and securing within the slot 114. Furthermore, a liquid channel 113 is formed between the first support plate 111 and the second support plate 112, allowing the degreasing agent to enter through the liquid channel 113 and immerse the first clamping plate 121 and the second clamping plate 122. The first clamping plate 121 has a first liquid passage hole 1211 extending through the thickness direction, and the second clamping plate 122 has a second liquid passage hole 1221 extending through the thickness direction. The degreasing liquid can act on the biological sheet 20 through the first liquid passage hole 1211 and the second liquid passage hole 1221, thereby degreasing the biological sheet 20. The biological sheet degreasing support 10 of this application clamps and fixes the biological sheet 20 by means of a support, preventing the biological sheet 20 from piling up, thereby improving the degreasing efficiency.
[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
