Description

Technical Field

[0001] This utility model relates to the field of specimen processing technology, and in particular to a tubular digestive tract tumor specimen processing device. Background Technology

[0002] The most common gastrointestinal tumors include colorectal cancer, gastric cancer, and esophageal cancer. The main treatment is comprehensive treatment with surgical resection as the primary method. For early-stage malignant tumors, surgical resection is the main approach, while for mid-to-late-stage tumors, radiotherapy and chemotherapy are used. Alternatively, surgery can be performed after radiotherapy and chemotherapy have downstaged the tumor.

[0003] Most gastrointestinal tumors are tubular in nature, and their staging is primarily based on the TNM staging system (Tumor, Node, Metastasis staging system). The TNM staging system is currently the internationally accepted method for cancer staging, used to describe the anatomical extent of the tumor. T indicates the depth of invasion, N indicates the location and number of metastatic lymph nodes, and M indicates whether there is distant metastasis. The depth of invasion is mainly determined pathologically: T1: Invasion to the submucosa (not reaching the muscularis propria); T2: Invasion to the muscularis propria; T3: Penetration of the muscularis propria to the subserosa or peritoneal adipose tissue (no peritoneal invasion); T4a: Penetration of the visceral peritoneum (direct invasion of the abdominal cavity); T4b: Invasion of adjacent organs (such as the bladder, uterus, prostate, etc.). Therefore, the TNM staging directly determines the patient's treatment approach and prognosis.

[0004] When determining the depth of invasion (Tumor) in TNM staging, the resected tubular gastrointestinal tumor specimen needs to be fully unfolded, fixed in formalin solution, and several specimens are then excised from appropriate sites. Finally, HE staining or immunohistochemical experiments are performed. Currently, there is no specialized device for unfolding and fixing tubular gastrointestinal tumor specimens. Typically, forceps or clamps are used to hold both ends of the duct, and the specimen is cut along its long axis with a scalpel. The surface is then washed with water to remove blood clots and other contaminants, followed by immersion in formalin or similar solutions for fixation. Because gastrointestinal tumor specimens are relatively soft, the cutting process is inconvenient, and the cylindrical shape of the specimen often remains curled after cutting, making it difficult to clean, fix, and section the lining. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a tubular digestive tract tumor specimen processing device.

[0006] To achieve the above objectives, the present invention can adopt the following technical solution: The present invention relates to a tubular digestive tract tumor specimen processing device, comprising a processing table, and a waste liquid collection tank, a specimen washing tank, and a specimen fixing tank disposed on the processing table; wherein, the waste liquid collection tank is covered with a leakage perforated plate, and a plurality of fixing posts are inserted into the leakage perforated plate; a rotating plug driven by a motor is sealed through the tank wall of the specimen washing tank and the specimen fixing tank, and a specimen fixing frame is adapted to be inserted into the rotating plug; a T-shaped sliding groove is provided on one side of the specimen fixing frame, a pair of first sliders and a pair of second sliders are adapted to slide in the transverse channel of the T-shaped sliding groove, and a third slider is adapted to slide in the longitudinal channel of the T-shaped sliding groove; a pair of horizontal clamping rods are fixedly connected to the two first sliders, and clamping grooves are provided on the two horizontal clamping rods; two second sliders are located between the two first sliders, and transverse moving support rods adapted to be fixed in the clamping grooves are provided on them; a longitudinal moving support rod parallel to the transverse moving support rods is provided on the third slider.

[0007] Furthermore, the specimen cleaning tank and the specimen fixing tank are arranged side by side. At this time, an integral sealing cover can be fitted onto the specimen cleaning tank and the specimen fixing tank to prevent contamination inside the specimen cleaning tank and the specimen fixing tank.

[0008] Furthermore, to facilitate liquid injection and drainage, the specimen cleaning tank and the specimen fixing tank are respectively provided with injection pipes near the top of the tank wall, and the waste liquid collection tank, the specimen cleaning tank and the specimen fixing tank are provided with drainage pipes near the bottom of the tank wall.

[0009] Furthermore, a stepped groove is provided at the edge of the waste liquid collection tank to fit and secure the leakage orifice plate, ensuring that the leakage orifice plate is securely sealed on the waste liquid collection tank. In addition, the height of the stepped groove should be less than the thickness of the leakage orifice plate to facilitate easy removal of the leakage orifice plate secured in the stepped groove.

[0010] Furthermore, the length of the transverse support rod is greater than that of the horizontal clamping rod, and the front ends of the two horizontal clamping rods are hinged to auxiliary fixing hooks for rotating and locking onto the transverse support rod. The auxiliary fixing hooks can further fix the transverse support rod located in the clamping groove.

[0011] The advantages of this invention are that it can easily expand and support duct-shaped digestive tract tumor specimens using the transverse support rod on the second slider and the longitudinal support rod on the third slider, thus facilitating cutting along the long axis of the specimen. Simultaneously, it can use the horizontal clamping rod on the first slider and the transverse support rod on the second slider to clamp the specimen, easily achieving specimen fixation and unfolding. This allows for automatic cleaning and formalin solution immersion fixation of the specimen using a motor-driven rotary plug on the specimen cleaning tank and specimen fixing tank, making the entire specimen processing process simpler and easier. It ensures precise and convenient specimen cutting, easily clamps and unfolds both ends of the specimen, prevents specimen curling, and greatly improves the efficiency of specimen cleaning, fixation, and section observation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 As shown, the tubular digestive tract tumor specimen processing device of this utility model includes a processing table 1 for processing tubular digestive tract tumor specimens for TNM staging. The processing table 1 has a rectangular structure and is provided with a waste liquid collection tank 2, a specimen washing tank 3, and a specimen fixing tank 4. The waste liquid collection tank 2, the specimen washing tank 3, and the specimen fixing tank 4 are all open-top cavities. The waste liquid collection tank 2 is used to collect the waste liquid generated during specimen processing to prevent waste liquid from flowing out and causing pollution. The specimen washing tank 3 is used to add clean water to clean the blood clots and other stains on the specimen surface. The specimen fixing tank 4 is used to add formalin solution to soak and fix the specimen.

[0017] Specifically, the waste liquid collection tank 2 is covered with a perforated plate 5 to allow waste liquid to flow down into the waste liquid collection tank 2 through the holes in the perforated plate 5 during specimen experiments. To ensure that the perforated plate 5 is securely sealed to the waste liquid collection tank 2, a stepped groove 6 should be provided at the edge of the waste liquid collection tank 2 to fit and secure the perforated plate 5. The height of the stepped groove 6 should be less than the thickness of the perforated plate 5, ensuring both stable securing of the perforated plate 5 and easy removal of the perforated plate 5 secured in the stepped groove 6. In addition, multiple fixing posts 7 are provided on the perforated plate 5. The fixing posts 7 are fitted and inserted into the holes in the perforated plate 5, and can be easily inserted into any hole on the perforated plate 5 as needed, so that the string used to stretch the specimen can be helped to be secured to the fixing posts 7, ensuring the stability of the specimen.

[0018] The specimen cleaning tank 3 and the specimen fixing tank 4 are arranged side by side and located on one side of the waste liquid collection tank 2. A one-piece sealing cover 8 can then be fitted onto the specimen cleaning tank 3 and the specimen fixing tank 4 to prevent contamination within them. Furthermore, a rotary plug 10 driven by a motor 9 is sealed and inserted into the walls of both the specimen cleaning tank 3 and the specimen fixing tank 4. A specimen holder 11 for fixing the specimen is fitted onto each rotary plug 10. Since the two rotary plugs 10 are located within the cavities of the specimen cleaning tank 3 and the specimen fixing tank 4 respectively, the specimen holder 11 should be located within the corresponding cavity regardless of which rotary plug 10 it is inserted into. Driven by the motor 9, the specimen holder 11 will rotate along with the rotary plug 10.

[0019] The specimen fixation frame 11 is used to clamp and fix tubular digestive tract tumor specimens, thereby cooperating with the waste fluid collection tank 2, specimen washing tank 3, and specimen fixation tank 4 to complete the cleaning, fixation, and sectioning observation of the specimens. Figure 2As shown, the specimen holder 11 has a T-shaped structure to improve its weight reduction. A T-shaped groove 12 is provided on one side of the specimen holder 11. A pair of first sliders 13 and a pair of second sliders 14 slide within the transverse channel of the T-shaped groove 12, and a third slider 15 slides within the longitudinal channel of the T-shaped groove 12. Two forward-extending horizontal clamping rods 16 are fixedly connected to the two first sliders 13, forming a pair. Each horizontal clamping rod 16 has a clamping groove 17 of the same length as its length. The clamping grooves 17 on the flat clamping rod 16 are arranged facing each other; the two second sliders 14 are located between the two first sliders 13. Each second slider 14 is provided with a transverse support rod 18 that can be adapted and locked with the clamping groove 17. The third slider 15 is provided with a longitudinal support rod 19 that is parallel to the transverse support rod 18. The transverse support rod 18 and the longitudinal support rod 19 can easily expand the duct-type digestive tract tumor specimen. At this time, the duct-type digestive tract tumor specimen is further clamped and fixed by the adaptation and locking of the transverse support rod 18 with the clamping groove 17.

[0020] In addition, in order to further secure the transverse support rod 18 that is locked in the clamping groove 17, such as Figure 3 As shown, the length of the transverse support rod 18 can also be designed to be greater than that of the horizontal clamping rod 16, that is, the length of the transverse support rod 18 is greater than that of the clamping groove 17. When the transverse support rod 18 is secured in the clamping groove 17, its front end will extend forward out of the clamping groove 17. At this time, an auxiliary fixing hook 20 for rotating and locking onto the transverse support rod 18 is hinged to the front end of the horizontal clamping rod 16 through a hinge shaft. Thus, the transverse support rod 18 located in the clamping groove 17 can be further fixed by the auxiliary fixing hook 20, so that the transverse support rod 18 and the horizontal clamping rod 16 can clamp the duct-type digestive tract tumor specimen more securely. To further facilitate the injection of liquid into the specimen cleaning tank 3 and the specimen fixing tank 4, injection pipes 21 can be installed near the top of the tank walls of the specimen cleaning tank 3 and the specimen fixing tank 4 respectively. To further facilitate the discharge of waste liquid from the waste liquid collection tank 2, the specimen cleaning tank 3 and the specimen fixing tank 4, drain pipes 22 can be installed near the bottom of the tank walls of the waste liquid collection tank 2, the specimen cleaning tank 3 and the specimen fixing tank 4. The three drain pipes 22 can be independent pipes, or they can be connected into one main pipe to easily discharge the waste liquid in each tank cavity.

[0021] In use, firstly, slide the two transverse support rods 18 and one longitudinal support rod 19 towards the center of the T-shaped groove 12; then, place the tract-type gastrointestinal tumor specimen requiring TNM staging, removed from the patient's body, onto the transverse support rods 18 and longitudinal support rod 19, and slide the transverse support rods 18 and longitudinal support rod 19 outward again to expand the specimen; then, secure the two transverse support rods 18 into the clamping grooves 17 of the two horizontal clamping rods 16, and use auxiliary... The auxiliary fixation hook 20 is used to further fix the transverse support rod 18, so that the transverse support rod 18 and the horizontal clamping rod 16 work together to clamp the specimen; finally, the upper wall of the specimen between the two transverse support rods 18 is cut open with a scalpel, and the two transverse support rods 18 are moved outward again and the longitudinal support rod 19 is moved upward, so that the specimen is pulled flat under the clamping action of the horizontal clamping rod 16 and the transverse support rod 18, thus completing the specimen unfolding operation and preventing the specimen from curling up.

[0022] Once the specimen is unfolded, the specimen holder 11 can be inserted into the rotary plug 10 inside the specimen cleaning tank 3. Water is then injected into the specimen through the injection tube 21 on the specimen cleaning tank 3. At the same time, the corresponding motor 9 is turned on, which drives the specimen holder 11 to rotate inside the specimen cleaning tank 3, thus easily completing the specimen cleaning operation.

[0023] After the specimen cleaning is completed, the waste liquid in the specimen cleaning tank 3 can be drained, and the specimen holder 11 can be removed and inserted into the rotating plug 10 in the specimen holder 4. Then, formalin solution is added into the specimen holder 4 through the injection tube 21, so that the specimen on the specimen holder 11 is immersed in formalin solution. After a certain period of time, the immersion and fixation of the specimen is completed.

[0024] After specimen fixation is completed, the waste liquid in the specimen fixation tank 4 can be drained, and the specimen fixation frame 11 can be removed. The specimen can then be removed from the specimen fixation frame 11 and fixed on the leakage plate 5 for subsequent experiments. The entire operation is simple and easy to perform, with precise cutting, which can easily achieve specimen fixation and unfolding, prevent specimen curling, facilitate specimen cleaning and formalin solution immersion fixation, and greatly improve the efficiency of specimen cleaning, fixation, and section observation.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
