Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reproductive medical equipment, in particular to an ovarian tissue cutting board. Background Art
[0002] Generally speaking, freezing ovaries means preserving female fertility, usually called cryopreservation of ovarian tissue. Generally, young women who have tumors or cancer before having children need chemotherapy and radiotherapy to be cured. Both chemotherapy and radiotherapy will cause the loss or damage of follicles in the gonads, that is, the ovaries. After recovery, there will be no follicles in the ovaries. At this time, it is generally recommended to freeze the ovarian tissue before chemotherapy and radiotherapy, and then move the ovaries back after the cancer or tumor is cured. This is the purpose of cryopreservation of ovarian tissue.
[0003] Ovarian tissue cryopreservation is a fertility preservation method that uses the principles of cryobiology to freeze ovarian tissue. It is an effective method for pre-pubertal women and women whose chemotherapy and radiotherapy cannot be postponed to preserve fertility. This technology does not remove the entire ovary, but generally cuts part of the ovarian tissue and freezes it in vitro. Ovarian tissue needs to be pre-processed before it can be cryopreserved. The current mature method is to slice the ovarian tissue with a scalpel. After the ovarian tissue is cut into slices, it will be placed in a cryoprotectant for pre-cooling and equilibrium, and then placed in a cryotube containing the cryoprotectant to begin freezing.

Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figure 1-Figure 4As shown in the figure, an ovarian tissue cutting plate is provided, including a containing vessel 11 and an operating table 12, the containing vessel 11 is provided with an opening upward, the operating table 12 is placed in the containing vessel 11 through the opening, the operating table 12 includes a bottom plate 13, the outer periphery of the bottom plate 13 extends upward to form a fence 15, a cutting area 16 is provided on the bottom plate 13, an area adjacent to the cutting area 16 on the bottom plate 13 is recessed and extends downward to form a slope, discharge ports 17 connected to the containing vessel 11 are spaced apart on the slope formed by the recessed extension on the bottom plate 13, and scale lines are provided on the cutting area 16.
[0026] The outer periphery of the top of the container 11 extends in a radial direction away from the center of the container 11 to form a boss, and the outer edge of the boss extends upward to form a limiting step with the boss, and the limiting step 18 supports the operating table 12. The operating table 12 is built into the container 11 through the opening, which can reduce the overall volume and height and save space. The operating table 12 and the container 11 are detachable. The operating table 12 is separated to facilitate the removal of the wetting liquid in the container 11, and the operating table 12 can be cleaned.
[0027] The container 11 and the operating table 12 are both cylindrical structures, or both are rectangular structures. The container 11 is made of glass or plastic, preferably glass, and the operating table 12 is made of glass or medical stainless steel, preferably medical stainless steel. The cutting area 16 is responsible for cutting, and the cutting board is made of medical stainless steel, which is convenient for sterilization and is safe and non-toxic to ovarian tissue and oocytes.
[0028] The cutting area 16 is located in the middle of the bottom plate 13, and a plurality of discharge ports 17 are provided, and the discharge ports 17 are arranged in an array on the slope of the outer periphery of the cutting area 16. Holes are designed around the cutting area 16 to allow the culture fluid to pass through the bottom plate 13 to keep the ovarian tissue moist, and also to facilitate the clamping of tweezers to remove the bottom plate 13 from the culture dish.
[0029] The discharge ports 17 are all located on the slope of the outer periphery of the cutting area 16, which is conducive to the timely and rapid discharge of the wetting liquid; the discharge ports 17 are strip-shaped holes, and the longitudinal axis of the discharge ports 17 is set at an angle offset from the radial direction of the cutting area 16. Multiple discharge ports 17 are evenly distributed around the outer periphery of the cutting area 16, which is conducive to the complete discharge of the wetting liquid and improves the discharge efficiency.
[0030] It should be noted that the cutting area 16 on the bottom plate 13 is a plane setting, and the position of the cutting area 16 is higher than the position of the discharge port 17. After the ovarian tissue is cut, the operating table 12 can be taken out and rinsed to collect the oocytes eluted in the rinsing fluid to increase the recovery efficiency.
[0031] The cutting area 16 is provided with right angle scales, and when the ovary is placed on it, the size of the ovary can be directly measured, which is convenient for photographing and recording.
[0032] The bottom surface of the operating table 12 extends downward to form a surrounding guide plate 19 surrounding the discharge port 17 and extending into the accommodating container 11, which can guide the wetting liquid discharged from the discharge port 17 to flow directly to the accommodating container 11, and prevent the wetting liquid from flowing along the bottom surface of the operating table 12 to the edge of the operating table 12.
[0033] The outer edge of the bottom plate 13 extends upward to form a barrier 15 , which blocks the splashing of the wetting liquid and prevents the wetting liquid from flowing to the gap between the operating table 12 and the accommodating container 11 and accumulating or flowing away from the edge of the operating table 12 .
[0034] According to the use requirements, the wetting liquid injected into the accommodating container 11 can fully immerse the cutting area 16, and the surface of the cutting area 16 is provided with anti-skid patterns to ensure that the ovary will not slide or shift during the cutting process.
[0035] When in use, the ovary to be cut is placed on the cutting area 16 of the bottom plate 13, the size of the ovary is measured, and after taking photos and recording, the ovary is cut. After cutting, the cutting area is rinsed, and the rinse liquid enters the accommodating vessel 11 through the discharge port 17. The adjacent discharge port 17 is clamped by tweezers to separate the accommodating vessel 11 from the operating table 12, and the oocytes shed in the accommodating vessel 11 are promptly recovered, and then the accommodating vessel 11 and the operating table 12 are cleaned and disinfected.
[0036] The utility model uses the above embodiments to illustrate the technical concept of the utility model, but the utility model is not limited to the above embodiments, that is, it does not mean that the utility model must rely on the above embodiments to be implemented.
