Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, and specifically, to a pathological specimen fixing bag. Background Art
[0002] To ensure the immediate and thorough fixation of surgically resected specimens, the common practice is to place the specimens in a special fixing bag and then pour a fixing liquid approximately ten times the volume of the specimens. This method aims to achieve rapid and comprehensive fixation of the specimens. However, when the density of the specimens is lower than that of the fixing liquid, they tend to float on the surface of the fixing liquid, which may result in incomplete fixation.
[0003] In actual work, to address this problem, usually two methods are adopted:
[0004] 1. Using the wet gauze covering method: Cover the floating specimens with wet gauze. Although this method can temporarily prevent the upper surface of the specimens from drying, during transportation, as the specimens shake, the gauze may separate from the specimens and sink to the bottom of the bag, resulting in the upper surface of the specimens still not being able to contact the fixing liquid.
[0005] 2. Using the fixing plate method: Fix the specimens on a special fixing plate with stainless steel needles, and then put the fixing plate and the specimens together into the fixing bag and add the fixing liquid. This method is usually used for specimens of endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) under digestive endoscopy because it requires professional personnel for operation. Since these specimens are thinner, the fixing liquid can penetrate better. However, for larger and thicker specimens, using the fixing plate may cause the contact area between the specimens and the fixing plate to be too large, thus hindering the full penetration of the fixing liquid and making the contact surface not fully fixed.
[0006] Therefore, a pathological specimen fixing bag is provided to solve the above problems. Content of the Utility Model
[0007] The utility model provides a pathological specimen fixing bag, which solves the problems such as the surface of the specimens cannot effectively contact the fixing liquid.
[0008] The technical solution of the utility model is as follows: It includes a bag body. It is characterized in that the lower end of the bag body is in the shape of a hollow cylinder, three T-shaped slide rails are equidistantly arranged on the inner surface of the lower end of the bag body, and a fixing component for fixing the specimens is slidably arranged on the three T-shaped slide rails. A sealing strip is arranged at the upper end of the bag body, and an opening is arranged at the upper end of the sealing strip.
[0009] The fixing component includes an annular adjusting component, fixing needles, and fixing caps. The adjusting component is slidably connected to three T-shaped sliding rails to adjust its annular size. The upper surface of the adjusting component is equidistantly provided with three groups of threaded holes. The lower end of the fixing needle is provided with external threads, and the fixing needles are threadedly connected to the internal of the three groups of threaded holes. The upper end of the fixing needle is detachably connected with a fixing cap.
[0010] As a preferred technical solution of the present utility model, the adjusting component includes three sliding blocks and three connecting blocks. The lower ends of the three sliding blocks are respectively slidably connected to the internal of the corresponding T-shaped sliding rails. Both ends of any one of the sliding blocks are slidably connected with connecting blocks, and adjacent two sliding blocks are connected by the connecting blocks.
[0011] As a preferred technical solution of the present utility model, both ends of the connecting block are provided with T-shaped convex blocks to prevent separation from the connected sliding block.
[0012] As a preferred technical solution of the present utility model, the distance between the lower surface of the connecting block and the inner surface of the bag body is greater than 1 cm.
[0013] As a preferred technical solution of the present utility model, the upper end of the fixing needle is provided with a depression, and the inner surface of the fixing cap is provided with a protrusion. The fixing cap is snap-fitted onto the fixing needle through the mutual cooperation of the protrusion and the depression.
[0014] The working principle and beneficial effects of the present utility model are as follows:
[0015] When the present utility model is in use, first, it is necessary to determine the size of the specimen. According to the size of the specimen, the adjusting component is adjusted. By sliding the three sliding blocks outward or inward, the annular diameter of the adjusting component can be made larger or smaller to be suitable for the specimen. Before putting the specimen into the bag, the fixing cap is removed. The upper end of the fixing needle is successively passed through the specimen, and then the exposed needle head is put back on the fixing cap, which does not hurt the hand. The specimen is suspended in the bag body under the action of the fixing needle. Finally, the fixing liquid is added to seal the bag. This specimen fixing bag adjusts the annular size through the adjusting component to adapt to the fixing of specimens of different sizes. The multiple fixing needles can penetrate the easily floating specimen, and then the fixing cap is buckled to suspend the specimen in the fixing liquid, ensuring that each surface of the specimen can be fully penetrated by the fixing liquid, providing a guarantee for making excellent pathological sections.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.
[0022] Embodiment
[0023] As Figures 1-3 shown, this embodiment proposes a pathological specimen fixing bag, including a bag body 1. The lower end of the bag body 1 is in a hollow cylindrical shape. The cylindrical shape is more suitable for larger and thicker specimens. Three T-shaped slide rails 2 are equidistantly arranged on the inner surface of the lower end of the bag body 1. A fixing component 3 for fixing the specimen is slidably arranged on the three T-shaped slide rails 2. A sealing strip 4 is arranged at the upper end of the bag body 1. An opening 5 is arranged at the upper end of the sealing strip 4. The sealing strip 4 can adopt a conventional sealing structure (concave-convex structure) to realize the sealing of the bag body 1.
[0024] Furthermore, the fixing component 3 includes an annular adjusting component 6, a fixing needle 7, and a fixing cap 8. The adjusting component 6 is slidably connected to the three T-shaped slide rails 2 to adjust its annular size. Since the sizes of the excised specimens are different, the annular size can be adjusted through the adjusting component 6 to adapt to the fixation of specimens of different sizes. Three groups of threaded holes are equidistantly arranged on the upper surface of the adjusting component 6. External threads are arranged at the lower end of the fixing needle 7. The fixing needle 7 is threadedly connected to the inside of each of the three groups of threaded holes. The upper end of the fixing needle 7 is detachably connected to the fixing cap 8. Fixing needles of different lengths and quantities are designed according to the size of the fixing bag. In this embodiment, there are 3 groups of fixing needles 7, and each group has 2. The fixing cap 8 is detachably connected to the needle tip of the fixing needle 7, so that the specimen is positioned and suspended in the fixing bag with the help of the fixing needle. Finally, a fixing liquid is added, and the height of the fixing liquid submerges the height of the fixing cap 8, so that the specimen will not float on the surface of the fixing liquid through the fixing cap 8.
[0025] The adjusting component 6 includes three sliding blocks 601 and three connecting blocks 602. The lower ends of the three sliding blocks 601 are respectively slidably connected inside the corresponding T-shaped slide rails 2. Connecting blocks 602 are slidably connected to both ends inside any one of the sliding blocks 601. Adjacent two sliding blocks 601 are connected by the connecting blocks 602. T-shaped bumps are provided at both ends of the connecting blocks 602 to prevent separation from the connected sliding blocks 601. When the three sliding blocks 601 slide outwards, the annular diameter of the adjusting component 6 can be made larger, which is suitable for larger specimens. On the contrary, when the three sliding blocks 601 slide inwards, the annular diameter of the adjusting component 6 can be made smaller, which is suitable for smaller specimens.
[0026] It should be noted that the distance between the lower surface of the connecting block 602 and the inner surface of the bag body 1 is greater than 1 centimeter. That is to say, there is a gap between the connecting block 602 and the inner surface of the bag body 1. With such a design, after adding the fixing liquid, the fixing liquid will fill the entire surface of the bag body 1 through this gap. That is to say, through the design of this distance, the lower surface of the specimen can fully contact the fixing liquid and be fully penetrated, which can effectively solve the problem that the contact area between the specimen and the bag body 1 is too large, thus hindering the penetration of the fixing liquid.
[0027] A depression is provided at the upper end of the fixing needle 7, and a protrusion is provided on the inner surface of the fixing cap 8. The fixing cap 8 is snap-fitted onto the fixing needle 7 through the mutual cooperation of the protrusion and the depression. Through the design of the fixing cap 8, it can effectively prevent the specimen from falling off the fixing needle 7.
[0028] When the present utility model is in use, first, it is necessary to determine the size of the specimen. Adjust the adjusting component 6 according to the size of the specimen. By sliding the three sliding blocks 601 outwards or inwards, the annular diameter of the adjusting component 6 can be made larger or smaller to be suitable for the specimen. Before putting the specimen into the bag, remove the fixing cap 8. Let the upper end of the fixing needle 7 pass through the specimen in sequence, and then put the exposed needle back on the fixing cap 8, which does not hurt the hand, so that the specimen is suspended in the bag body 1 under the action of the fixing needle. Finally, add the fixing liquid and seal the bag. This specimen fixing bag adjusts the annular size through the adjusting component 6 to adapt to the fixing of specimens of different sizes. Through multiple fixing needles 7, it can penetrate the easily floating specimen, and then buckle on the fixing cap 8 to suspend the specimen in the fixing liquid, ensuring that each surface of the specimen can be fully penetrated by the fixing liquid, providing a guarantee for making excellent pathological sections.
[0029] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
