Technical Field
[0001] This application relates to the field of medical device technology, and more specifically, to an ovarian tissue cutting table and cutting assembly. Background Technology
[0002] Ovarian freezing is a medical procedure performed on women at high risk of ovarian failure, commonly for cancer patients. It aims to prevent irreversible damage to ovarian function caused by cancer treatment, which could lead to early-onset ovarian insufficiency or even infertility. Before cancer treatment begins, a portion of the ovarian cortex tissue is removed and frozen. Once the patient is cured and in good health, the frozen ovarian tissue is transplanted back into the body to restore natural ovulation and fertility.
[0003] Ovarian freezing involves the necessary procedure of cutting ovarian cortical tissue. However, current ovarian tissue cutting methods lack precise and reliable cutting components, and the lack of corresponding direct measuring tools makes it difficult to control the cutting dimensions of the ovarian assembly.

[0022] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0023] The ovarian tissue cutting table in this application regulates the ovarian tissue to be cut by setting a necessary platform, and cuts the portion of the ovarian tissue protruding from the platform.
[0024] See Figure 1 and combined Figure 2 The ovarian tissue cutting stage of this utility model includes a base plate 1 and a laminated plate 2 stacked with the base plate 1.
[0025] The main function of the substrate 1 is to block the ovarian tissue at the cutting window 3, while the laminate 2 is specifically used to receive the ovarian tissue and, by pressing it at the cutting window 3, to make part of the ovarian tissue protrude at the cutting window 3 and fit it with the substrate 1 to obtain a regulated sample. Then, by using a transverse cutting method, the ovarian tissue protruding from the cutting window 3 is cut to obtain a frozen ovarian sample.
[0026] Based on the process described above, the laminated plate 2 in this utility model includes two layers, and each laminated plate 2 is provided with a cutting window 3.
[0027] By setting a scale 4 on the panel of the laminate 2, the size of the sample can be intuitively obtained through the size of the scale 4 corresponding to the cutting window 3, providing the necessary basis for the subsequent cryopreservation of ovarian tissue.
[0028] During the procedure, the ovarian tissue is pressed onto the laminated plate 2, allowing the cut ovarian tissue to protrude through the cutting window 3, facilitating standardized cutting.
[0029] There are gaps between the laminated plates 2 and between the laminated plates 2 and the substrate 1. Specifically, there are gaps between the two laminated plates 2 and between the laminated plates 2 and the substrate 1 in the middle layer, which allow the thin-film cutter to make transverse cuts. During the transverse cut, the ovarian tissue protruding from the cutting window 3 is cut.
[0030] The cutting table in this invention provides the necessary structural conditions for convenient cutting of ovarian tissue, while simplifying the cutting operation, making it simple and practical.
[0031] In one specific embodiment, in order to assemble the different structures described above, the substrate 1 and the laminate 2 are connected to the same connecting plate 5, and the overall assembly after connection is arranged in a T-shape.
[0032] Specifically, the extension direction of the connecting plate 5 is perpendicular to the extension direction of the two laminated plates 2, and they intersect perpendicularly, which facilitates the fixed connection of the substrate 1 and the laminated plates 2.
[0033] Furthermore, the length of the connecting plate 5 extends along the width of the laminate 2. In terms of connection, the connecting plate 5 is connected to the substrate 1 and the laminate 2 as a whole by bolts 6. The bolts 6 are arranged in pairs and spaced apart in the length of the connecting plate 5, which can ensure the reliability of the connection.
[0034] Bolt 6 is specifically an internal hex bolt 6, which passes through the connecting plate 5, the two laminated plates 2 and the base plate 1 in sequence. In order to prevent bolt 6 from protruding from the connecting plate 5 and the base plate 1, causing the cutting table to shake, the two ends of bolt 6 do not protrude from the top and bottom side plates.
[0035] In other words, the head of bolt 6 does not protrude from the surface of connecting plate 5. More importantly, the end face of bolt 6 does not protrude from the bottom wall of substrate 1, which can keep substrate 1 flush with the bottom surface and ensure the stability of the cutting table in the flat position.
[0036] Both the base plate 1 and the laminated plate 2 are rectangular strips of the same width, and they are overlapped in the width direction for easy handling. The fixed connection between the base plate 1 and the laminated plate 2 as a whole facilitates cutting operations while pressing on ovarian tissue.
[0037] In the specific operation, the index finger of the left hand can be used to press the ovarian tissue onto the cutting window 3 of the laminate 2, while the middle finger and thumb hold it in the width direction of the connecting whole. The right hand makes a transverse cut in the gap between the two laminate 2, thereby cutting the ovarian tissue that protrudes from the cutting window 3 and is attached to the substrate 1.
[0038] Structurally, one end face of the substrate 1 and the laminate 2 along the length direction is flush with the connecting plate 5, which can ensure the contact area between different plates and enhance stability.
[0039] The substrate 1 is set at the bottom of the ovarian tissue cutting stage, which can provide stable support and facilitate the adhesion of the ovarian tissue to the substrate 1 corresponding to the cutting window 3.
[0040] The cutting table in this embodiment specifically includes a connecting side and an infeed side. The connecting plate 5 is located on the other side of the transverse infeed portion, that is, the connecting plate 5 is located on the connecting side. The base plate 1 has a rounded chamfer 11 at the corner of the infeed side, which can prevent sharp corners from affecting the infeed and avoid the safety risks caused by sharp corners.
[0041] In another specific embodiment, the laminate 2 includes a middle laminate 21 and a top laminate 22. The length of the top laminate 22 is the same as the length of the substrate 1, and the length of the middle laminate 21 is less than the length of the top laminate 22.
[0042] This arrangement allows the shorter intermediate laminate 21 to be clamped between the top laminate 22 and the substrate 1, reducing the feed stroke of the sheet cutter between the two laminates 2.
[0043] The top stack plate 22 has a beveled corner 23 at the corner of the cutting side. The beveled corner 23 corresponds to the circular chamfer 11, which facilitates the slight lifting of the top stack plate 22.
[0044] Both the intermediate laminate 21 and the top laminate 22 are provided with cutting windows 3. The two cutting windows 3 are overlapped, which can regulate the ovarian tissue pressed on the cutting window 3 of the laminate 2.
[0045] At least a length is provided between the cutting window 3 and the connecting plate 5 to provide sufficient space for the pressing operation.
[0046] Meanwhile, the scale 4 is printed on the surface of the top laminate 22, including the horizontal and vertical intersecting length direction scale 41 and width direction scale 42, which can intuitively grasp the size of the cut sample.
[0047] The cutting window 3 includes a square window located at the center of the laminate 2. Auxiliary guide grooves 31 are provided at the four corners of the cutting window 3 and communicate with the cutting window 3. The auxiliary guide grooves 31 include through grooves that pass through the thickness direction of the laminate 2 and intersect perpendicularly with the four corners of the cutting window 3. This arrangement facilitates auxiliary cutting on the side of the board.
[0048] It should be noted that, in order to prevent the potential risk of scratches from lateral incision, it is necessary to ensure that the ovarian tissue has sufficient thickness and area. Furthermore, by setting up cutting stages with various sizes of cutting windows 3, the ovarian tissue can be fully filled in the cutting window 3 area, thus avoiding the risk.
[0049] In this invention, the substrate 1, the laminate 2, and the connecting plate 5 are all transparent acrylic sheets, which can provide a visible cutting environment and ensure the reliability of the cutting operation.
[0050] The edges of the substrate 1, the laminate 2 and the connecting plate 5 are respectively provided with bevels, which facilitates the transverse entry of the blade from the side of the cutting table, avoids contact between the thin blade and the edge of the plate during the cutting process, and thus reduces the generation of chips.
[0051] This utility model also provides an ovarian tissue cutting assembly, including a thin-blade cutter and the ovarian tissue cutting table described above. The thin-blade cutter enters horizontally from the side of the cutting table to cut the ovarian tissue protruding from the cutting window 3, ensuring a precise and reliable cutting operation to the greatest extent.
[0052] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0053] The above description is merely a preferred embodiment of this application and is 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.
