Description

Technical Field

[0001] This utility model relates to the field of experimental equipment, and in particular to a umbilical cord mesenchymal stem cell tissue cutter. Background Technology

[0002] An existing patent (publication number: CN213012857U) discloses an umbilical cord mesenchymal stem cell cutter, including a base and a male blade plate. The male blade plate includes a fixed frame and multiple male blades arranged parallel and equidistantly inside the fixed frame. A female blade is provided above the base, each engaging with one of the male blades. When the male blades are pressed down relative to the blade grooves between adjacent female blades, all the male blades engage with all the female blades to achieve cutting. The thickness of the male blade is equal to the width of the blade groove, and the thickness of the female blade is equal to the distance between adjacent male blades, with the thickness of the female blade being greater than the thickness of the male blade. The base includes a bottom plate and an upper protrusion convex on a horizontal plane relative to the bottom plate. Multiple blade grooves penetrate the upper protrusion to form the female blades. The male blades are hinged to the base. Hinge support portions are provided on both sides of the upper protrusion, and hinge shafts perpendicular to the length direction of the blade grooves are provided through these hinge support portions. However, the female and male blades on this cutter can only cut tissue into strip structures, not into better structures. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing an umbilical cord mesenchymal stem cell tissue cutter that can cut tissue into strip structures and further cut the strips into smaller structures.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A umbilical cord mesenchymal stem cell tissue cutter includes a fixed frame plate, vertical legs, a tissue receiving tray, a lower cutting blade, a U-shaped side plate, a second connecting ear, a middle cutting blade, a side connecting plate, a side fixing plate, an upper cutting blade, and a strip connecting plate. The lower part of the fixed frame plate is connected to the vertical legs, and four vertical legs are distributed at the four corners of the bottom of the fixed frame plate. The tissue receiving tray is placed below the fixed frame plate. The lower cutting blade is connected inside the fixed frame plate, and multiple lower cutting blades are evenly distributed inside the fixed frame plate. The second connecting ear is connected to the inner side of the fixed frame plate, and a group of second connecting ears are distributed on one side of the fixed frame plate. The side of the fixed frame plate is connected to the U-shaped side plate, and the inner side of the U-shaped side plate is connected to the first connecting ear, and a group of first connecting ears are distributed inside the U-shaped side plate. One end of the middle cutting blade is connected to the side connecting plate, and the other end of the middle cutting blade is connected to the side fixing plate.

[0006] Multiple intermediate cutting blades are evenly distributed between the side connecting plate and the side fixing plate. The side fixing plate has a mounting sleeve on its side. The two sides of the mounting sleeve fit into the No. 2 connecting lug. The mounting sleeve is connected to a set of No. 2 connecting lugs. The lower part of the intermediate cutting blade has multiple lower cutting grooves. The lower cutting blade is inserted into the lower cutting groove.

[0007] The upper part of the intermediate cutting plate has multiple upper cutting grooves. The upper part of the upper cutting plate is connected to a strip connecting plate. A set of strip connecting plates are distributed on the upper part of the upper cutting plate. The upper part of the strip connecting plate is connected to a strip mounting plate. The side of the strip mounting plate fits against a set of No. 1 connecting lugs. The strip mounting plate is connected to a set of No. 1 connecting lugs. Beneficial effects

[0008] 1. In this utility model, multiple vertical support legs support the bottom of the fixed frame plate, suspending the fixed frame plate below. This allows the tissue receiving tray to be placed below the fixed frame plate to receive the cut umbilical cord mesenchymal stem cell tissue. Multiple lower cutting blades are installed and fixed inside the fixed frame plate to cut the umbilical cord mesenchymal stem cell tissue. During operation, the umbilical cord mesenchymal stem cell tissue is laid on top of the multiple lower cutting blades. The two ends of the middle cutting blade are connected to the side connecting plate and the side fixing plate, respectively. The multiple middle cutting blades, the side connecting plate, and the side fixing plate form a middle cutting frame. The mounting sleeve is connected to the second connecting trunnion, so that the cutting frame is mounted on the fixed frame plate and can be rotated for use. The upper cutting blade, the strip connecting plate, and the strip mounting plate form an upper cutting frame. The side of the strip mounting plate is connected to the first connecting trunnion, so that the upper cutting frame is connected to the fixed frame plate and can be rotated for operation.

[0009] 2. In use, both the upper and middle shearing frames are rotated open. Umbilical cord mesenchymal stem cell tissue is placed on the lower cutting blade. The middle shearing frame is then rotated so that the lower cutting blade is inserted into the lower cutting groove, and the side convex plate of the connecting plate is inserted into the support slot to ensure the middle shearing frame is horizontal. The lower and middle cutting blades work together to cut the umbilical cord mesenchymal stem cell tissue into longitudinal strip structures. Then, the upper shearing frame is rotated until the upper cutting blade is inserted into the upper cutting groove. The upper and middle cutting blades work together to cut the strip structure of umbilical cord mesenchymal stem cell tissue into multiple block structures. The cut umbilical cord mesenchymal stem cell tissue falls into the tissue receiving tray. This device can not only cut tissue into strip structures, but also further cut the strips into smaller structures. Attached Figure Description
