Description

Technical Field

[0001] This utility model relates to the field of tissue section fixation device technology, and in particular to a container for fixing frozen tissue sections. Background Technology

[0002] In studies of spawning strategies in cephalopods and fish, the development of gonads and gametogenesis is a crucial aspect. The patterns of gonadal development and gametogenesis during the growth and development of these species often determine their spawning type and reproductive strategy. In routine tissue preparation, tissue sectioning is a vital technique, a primary method used in histology, embryology, biology, pathology, oncology, and other disciplines to observe physiological and pathological morphological changes in cells and tissues. Frozen sections are produced by rapidly cooling tissue to a certain hardness under low-temperature conditions.

[0003] In actual use, the tissue needs to be placed in a container and then rapidly frozen to harden it. Since the tissues vary in size, different inner diameter containers need to be selected according to the requirements to place the tissues. This requires preparing a large number of containers with different inner diameters. However, not all of these containers can be used, which can easily lead to waste of resources and has certain shortcomings.

[0004] Therefore, a container for fixing frozen sections of tissue is provided to solve the problems mentioned above. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1:

[0031] Reference Figure 1-7 A container for fixing frozen sections of tissue includes a storage tube 1, and further includes: an opening 101 disposed on the storage tube 1; multiple sets of clamping rings 3 disposed in a ring shape inside the storage tube 1, the clamping rings 3 being slidably connected inside the storage tube 1; an arc surface 301 disposed on the back of the clamping rings 3; a connecting rod 501 slidably connected inside the opening 101, the connecting rod 501 abutting against the arc surface 301, allowing the clamping rings 3 to move towards the center of the storage tube 1 by the connecting rod 501 abutting against the arc surface 301; a movable ring 5 sleeved on the storage tube 1, the connecting rod 501 being fixedly connected to the movable ring 5; a damping pad 6 disposed between the movable ring 5 and the storage tube 1; sealing caps 2 threadedly connected to both ends of the storage tube 1; a limiting tube 102 fixedly connected inside the storage tube 1; a limiting rod 302 fixedly connected to the clamping rings 3, the limiting rod 302 being slidably connected inside the limiting tube 102.

[0032] Multiple sets of clamping rings 3 are arranged in a ring shape inside the storage tube 1, with a certain gap between them, and can slide inside the storage tube 1. When they move to the limit, they can be spliced ​​into a complete circle. Each clamping ring 3 has an arc surface 301 on its back, which is used to interact with the connecting rod 501. When the connecting rod 501 moves downward against the arc surface 301, it generates a squeezing force, which causes the clamping ring 3 to move towards the center of the storage tube 1, thereby adjusting the storage space size of the storage tube 1, which is convenient for clamping and fixing tissue samples of different sizes.

[0033] A limiting rod 302 is fixedly connected to the clamping ring 3. The limiting rod 302 is slidably connected inside the limiting tube 102 to ensure that the clamping ring 3 can only slide smoothly in the axial direction inside the storage tube 1, so as to avoid its displacement or shaking during movement and ensure the accuracy and stability of clamping the tissue sample.

[0034] When using it, first place the tissue sample in the storage tube 1. Then, by moving the moving ring 5, the connecting rod 501 is driven to slide in the opening 101. The connecting rod 501 abuts against the arc surface 301, so that the clamping ring 3 moves towards the center of the storage tube 1 to initially clamp the tissue sample. Finally, the sealing cap 2 is threaded to both ends of the storage tube 1 to seal and preserve the sample for subsequent operations such as frozen sectioning.

[0035] Example 2:

[0036] Reference Figure 1-7 A container for fixing frozen sections of tissue is basically the same as in Example 1, but further: a cavity is provided inside the clamping ring 3, a movable plate 4 is slidably connected inside the cavity, a rubber head 401 is provided on the movable plate 4, the rubber head 401 passes through the clamping ring 3, a cam rod 7 is rotatably connected inside the cavity, a spring 303 is connected inside the cavity, the other end of the spring 303 is connected to the movable plate 4, the cam rod 7 abuts against the movable plate 4, and a toothed groove 8 is provided on the cam rod 7.

[0037] The clamping ring 3 has a cavity, and a movable plate 4 is slidably connected in the cavity. A rubber head 401 is provided on the movable plate 4. The rubber head 401 passes through the clamping ring 3. When it is necessary to further clamp the tissue sample, the rubber head 401 can directly contact the sample, providing better friction and buffering effect to avoid damage to the sample. At the same time, it can further reduce the inner diameter of the clamp, making it easier to fix some smaller tissues.

[0038] Inside the cavity, a cam rod 7 is rotatably connected, and a spring 303 is also connected inside the cavity. The other end of the spring 303 is connected to the moving plate 4. The cam rod 7 abuts against the moving plate 4. When the cam rod 7 is rotated, its protruding part will squeeze the moving plate 4, so that the moving plate 4 overcomes the elastic force of the spring 303 and pushes the rubber head 401 out, further enhancing the clamping effect on the sample. In addition, the cam rod 7 is provided with a toothed groove 8, which makes it easy to use tools such as toothed levers to rotate the cam rod 7, improving the convenience of operation.

[0039] If a further enhanced clamping effect is required, a tool such as a toothed lever can be used to move the toothed groove 8 on the cam rod 7, causing the cam rod 7 to rotate. The protruding part of the cam rod 7 presses against the moving plate 4, overcoming the elasticity of the spring 303, and pushing the rubber head 401 to extend, making closer contact with the tissue sample, thus completing the firm fixation of the tissue sample.

[0040] This invention, through the setting of connecting rod 501 and arc surface 301, can adjust the position of clamping ring 3, thereby adjusting the inner diameter of storage tube 1, so as to be suitable for fixing tissues of different sizes, without the need to prepare storage tubes 1 with different apertures, and facilitates the use of frozen section fixation.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
