Description

Technical Field

[0001] This utility model relates to the field of minimally invasive surgical specimen processing technology, and in particular to a fixation and measuring plate for full-thickness resection specimens in ultra-minimally invasive digestive endoscopy. Background Technology

[0002] With the rapid development of modern medical technology, minimally invasive surgery has been widely used in clinical treatment due to its significant advantages such as minimal trauma and rapid recovery. In the diagnostic and treatment process of minimally invasive surgery, the precise fixation and measurement of the fully resected tissue specimen is a core step in subsequent pathological analysis, and its results directly affect the accurate diagnosis of the disease and the scientific formulation of the treatment plan.

[0003] However, current traditional specimen fixation and measurement methods reveal numerous significant limitations when applied to minimally invasive surgery. Regarding specimen damage, traditional fixation methods commonly involve direct puncture of the specimen with a pin, a physical puncture method with obvious drawbacks. Pin puncture alters the specimen's morphology and causes severe cell damage. Especially in practice, multiple fixations and rotations of the specimen are often necessary, making secondary damage almost unavoidable. This significantly interferes with the accuracy of pathological analysis results and substantially increases the risk of errors in the physician's diagnosis.

[0004] From an operational perspective, traditional methods are complex and cumbersome. When measuring specimen dimensions, the specimen must first be carefully removed from the fixation plate, then measured using calipers or other measuring tools, and finally refixed. This series of operations not only consumes a significant amount of time, prolonging the pathological analysis cycle, but also increases the complexity and probability of errors. In time-sensitive surgical scenarios, such as rapid intraoperative pathological diagnosis, every second is crucial. The time-consuming nature of traditional procedures may delay diagnosis, thereby affecting the timely and accurate formulation of subsequent treatment plans.

[0005] In addition, poor visibility is also a major problem faced by traditional techniques. The opaque fixation plate and pins will obstruct the specimen when fixing it, making it difficult to observe the details of the specimen comprehensively and clearly during the fixation process. This is undoubtedly a major obstacle for pathological analysis work that requires precise measurement and recording of specimen size, shape and lesion characteristics. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by providing a fixation and measurement plate for full-thickness resection specimens in minimally invasive endoscopic surgery. This plate supports and fixes the surgical specimen, enabling direct measurement and enhanced visibility of the specimen. It also reduces secondary damage to the specimen and ensures its integrity.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A measuring plate for fixing a full-thickness resection specimen in a minimally invasive endoscopic surgery includes a measuring plate body and fixing components. The measuring plate body is used to support and observe the surgical specimen. The measuring plate body has scale values ​​on its edge. The measuring plate body is a transparent plate. The bottom of the measuring plate body is provided with an illumination component for illuminating it. Multiple fixing components are provided and can be detachably installed on the measuring plate body.

[0009] Preferably, the fixing component includes a connecting plate, one side of which is provided with a pressing end for pressing the specimen, and the measuring plate is provided with a positioning groove corresponding to the pressing end. The positioning groove enables the pressing end to better press and fix the specimen.

[0010] Preferably, the connecting plate has a fixed end on the same side as the pressing end, the measuring plate has a fixing groove that mates with the fixed end, and the connecting plate has a pressing block on the side away from the fixed end. The fixed end on the connecting plate mates with the fixing groove on the measuring plate to form a stable fixing structure, ensuring that the fixing component will not easily loosen or fall off when fixing the specimen. The pressing block on the side away from the fixed end facilitates hand operation by medical staff, further improving the convenience and stability of specimen fixing. The fixed end and the fixing groove can be inserted through an interference fit.

[0011] Preferably, the plurality of fixing members are equidistantly distributed along the four sides of the measuring plate, which can accommodate specimens of different sizes and shapes. By selecting fixing members at different positions for fixation, the versatility and applicability of the device are improved.

[0012] Preferably, the measuring plate is provided with multiple positioning slots and fixing slots for inserting fixing components. The multiple positioning slots and fixing slots enhance the flexibility and applicability of the device. Medical personnel can freely select the appropriate fixing component for installation according to the actual situation of the specimen to ensure that the specimen can be stably fixed. The number and position of the positioning slots and fixing slots can be customized according to the size of the measuring plate and the usage requirements.

[0013] Preferably, the lighting component includes a base frame located below the measuring plate. Lighting strips for illuminating the measuring plate are evenly distributed within the base frame. These lighting strips can be adjustable LED strips with adjustable brightness and color temperature. A control panel for adjusting the brightness and color temperature of the lighting strips is connected externally via wires. The illumination from the lighting strips provides sufficient light for medical personnel to observe and measure specimens, enhancing the visibility of specimen details and ensuring the accuracy of measurement and observation.

[0014] Preferably, the pressing end of the fixing member has a blunt tip structure, and the end of the pressing end is provided with a medical-grade silicone elastic layer. The pressing end of the fixing member adopts a blunt tip structure and is provided with a medical-grade silicone elastic layer, which can effectively reduce physical damage to the specimen. The blunt tip structure avoids the puncture of the specimen by sharp objects, and the silicone elastic layer can increase the contact friction between the specimen and the pressing end, so that the pressing end can better press and fix the specimen.

[0015] Preferably, the scale values ​​are printed with high-contrast fluorescent ink, which ensures that the scale values ​​are clearly visible under different lighting conditions, making it easier for medical staff to accurately read the measurement data and reducing measurement errors.

[0016] Preferably, both the measuring plate and the fixing element are made of medical-grade polymethyl methacrylate (PMMA). This material has good transparency, chemical stability, and biocompatibility. High transparency ensures the clarity of the specimen observation, chemical stability makes it less susceptible to corrosion by chemical substances, and biocompatibility ensures that it will not have an adverse effect on the specimen.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention allows for direct measurement of specimens by providing graduated values ​​on the edge of the measuring plate, eliminating the need for additional measuring tools. Furthermore, the fixed components secure the specimens, preventing puncture damage and significantly reducing the risk of physical damage during the fixation process, thus ensuring the integrity of the specimens.

Example

[0029] Please see Figure 1-4 A measuring plate for fixing specimens in minimally invasive endoscopic surgery includes a measuring plate body 1 and fixation components 2. The measuring plate body 1 is used to support and observe the surgical specimen. The measuring plate body 1 has scale values ​​11 on its edge. The measuring plate body 1 is a transparent plate. The bottom of the measuring plate body 1 is equipped with an illumination component 3 for illuminating it. Multiple fixation components 2 are provided and can be detachably installed on the measuring plate body 1. The scale values ​​11 on the edge facilitate direct measurement of specimen size without the need for additional measuring tools, reducing operation steps and improving measurement efficiency. The illumination component 3 at the bottom can provide sufficient light for observation and measurement of the specimen in low-light environments, facilitating observation by medical staff or imaging by image acquisition equipment. The line width of the scale values ​​11 can be 0.2 mm, the interval can be 1 cm, and the scale range can be 0-30 cm.

[0030] The fixing component 2 includes a connecting plate 21. One side of the connecting plate 21 is provided with a pressing end 23 for pressing the specimen. The measuring plate 1 is provided with a positioning groove 12 corresponding to the pressing end 23. The positioning groove 12 enables the pressing end 23 to press and fix the specimen better.

[0031] A fixed end 24 is provided on the same side as the pressing end 23 on the connecting plate 21. A fixing groove 13 is provided on the measuring plate 1 to connect with the fixed end 24. A pressing block 22 is provided on the side of the connecting plate 21 away from the fixed end 24. The fixed end 24 on the connecting plate 21 and the fixing groove 13 on the measuring plate 1 are connected to form a stable fixing structure to ensure that the fixing part 2 will not easily loosen or fall off when fixing the specimen. The pressing block 22 is provided on the side away from the fixed end 24 to facilitate hand operation by medical staff and further improve the convenience and stability of fixing the specimen. The fixed end 24 and the fixing groove 13 can be inserted through an interference fit.

[0032] Multiple fasteners 2 are equidistantly distributed along the four sides of the measuring plate 1, which can accommodate specimens of different sizes and shapes. By selecting fasteners 2 at different positions for fixation, the versatility and applicability of the device are improved.

[0033] The measuring plate 1 is provided with multiple positioning slots 12 and fixing slots 13 for inserting the fixing parts 2. The multiple positioning slots 12 and fixing slots 13 enhance the flexibility and applicability of the device. Medical staff can freely choose the appropriate position of the fixing parts 2 for installation according to the actual situation of the specimen, so as to ensure that the specimen can be stably fixed. The number and position of the positioning slots 12 and fixing slots 13 can be customized according to the size of the measuring plate 1 and the usage requirements.

[0034] The lighting component 3 includes a base frame 31 located below the measuring plate 1. Lighting strips 32 are evenly distributed within the base frame 31 to illuminate the measuring plate 1. The lighting strips 32 can be LED strips with adjustable brightness and color temperature. The lighting strips 32 are connected to a control panel via wires to adjust their brightness and color temperature. The illumination from the lighting strips 32 provides sufficient light for medical personnel to observe and measure specimens, enhancing the visibility of specimen details and ensuring the accuracy of measurement and observation.

[0035] The pressing end 23 of the fixing member 2 has a blunt head structure and a medical-grade silicone elastic layer at the end of the pressing end 23. The blunt head structure and the medical-grade silicone elastic layer of the pressing end 23 of the fixing member 2 can effectively reduce physical damage to the specimen. The blunt head structure avoids the puncture of the specimen by sharp objects, and the silicone elastic layer can increase the contact friction between the specimen and the pressing end 23, so that the pressing end 23 can better press and fix the specimen.

[0036] The scale value 11 is printed with high-contrast fluorescent ink, which is clearly visible under different lighting conditions, making it convenient for medical staff to accurately read measurement data and reduce measurement errors.

[0037] Both the measuring plate 1 and the fixing element 2 are made of medical-grade polymethyl methacrylate (PMMA). This material has good transparency, chemical stability and biocompatibility. High transparency ensures the clarity of the specimen observation, chemical stability makes it less susceptible to chemical corrosion, and biocompatibility ensures that it will not have an adverse effect on the specimen.

[0038] When using this device, the specimen removed during endoscopic surgery is carefully placed on the measuring plate 1. Based on the size and shape of the specimen, the appropriate fixing slots 13 on the four sides of the measuring plate 1 are selected. The fixing end 24 of the fixing member 2 is aligned with the fixing slot 13 and inserted, while its pressing end 23 is aligned with the positioning slot 12. Then, the pressing block 22 is gently pressed, allowing the blunt end 23 to gently press against the specimen edge through the silicone elastic layer, thus fixing the specimen. During the fixing process, it is important to ensure the specimen is flat and avoid wrinkles. After fixing the specimen, the illumination member 3 is turned on. The light emitted by the illumination strip 32 shines through the transparent measuring plate 1, illuminating the specimen. Medical personnel can directly use the scale values ​​11 on the edge of the measuring plate 1 to measure the specimen's dimensions and read the data. Simultaneously, due to sufficient illumination and the transparency of the measuring plate 1, details of the specimen, such as the morphology and color of lesions, can be clearly observed. Furthermore, with the aid of external image acquisition equipment, relatively clear image acquisition can be performed.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
