Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a pathology collection device for use on an operating table. Background Technology

[0002] To clarify the nature of the lesions in the patient's tissues and obtain a more accurate diagnosis, medical staff need to collect pathological specimens in pathology bottles during the surgical procedure for postoperative pathological examination. In current technology, pathology bottles typically use a negative pressure system to aspirate small pathological specimens. However, this system also draws in intraoperative materials (such as pathological specimens, fluids, or microsurgical instruments), resulting in the collected specimens being contaminated with numerous impurities (such as blood or urine, and surgical instruments like tiny cotton swabs or balls). This contamination easily affects the accuracy of the pathological examination. Furthermore, medical staff need to cut open the pathology bottles to collect the specimen a second time, selecting it from the impurities. This increases the workload for medical staff and exposes impurities to the outside environment. Liquids (tissue fluid or urine) within the impurities can easily splash out, significantly increasing the risk of infection for medical staff if the patient has an infectious disease. This poses a significant safety hazard and warrants improvement. Utility Model Content

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The following is for reference. Figures 1-7 This invention describes a pathology collection device for an operating table according to an embodiment of the present invention.

[0032] like Figures 1-7As shown, the pathology collection device for the operating table according to an embodiment of the present invention includes a collection bottle 100 and a negative pressure component (not shown in the figure). The collection bottle 100 may include a bottle body 10 and a first cap 20. The bottle body 10 may define a receiving cavity 11 and may have a bottle opening 12. The receiving cavity 11 can communicate with the outside through the bottle opening 12. The first cap 20 and the bottle body 10 are detachably connected, so that the first cap 20 can open or close the bottle opening 12. For example, the first cap 20 can be connected to the bottle body 10 to close the bottle opening 12, which can prevent the intraoperative material in the bottle body 10 from being directly exposed to the outside, reduce the risk of infection for medical staff, and reduce the safety hazards of the operation. Alternatively, the first cap 20 and the bottle body 10 can be detached to open the bottle opening 12, which makes it easier for medical staff to take out the pathology specimen.

[0033] The first cover 20 may be provided with a first tube 21 and a second tube 22, one end of the first tube 21 (e.g., Figure 3 The lower end shown can extend into the receiving cavity 11, and the other end of the first tube 21 (as shown) Figure 3 The rear end shown can be connected to the operating table (not shown in the figure), so that the bottle 10 can collect intraoperative materials through the first tube 21, and one end of the second tube 22 (as shown in the figure) can be connected to the operating table. Figure 3 The lower end shown can extend into the receiving cavity 11, and the other end of the second tube 22 (as shown) Figure 3 The front end shown can be connected to a negative pressure component (such as a negative pressure bottle).

[0034] The negative pressure device can draw air from the bottle 10 through the second tube 22 to generate negative pressure inside the bottle 10. The first tube 21 can draw in surgical materials from the operating table under the action of negative pressure inside the bottle 10, so as to draw the surgical materials into the bottle 10. A filter can be installed in the receiving cavity 11. One end of the first tube 21 and one end of the second tube 22 can be connected through the filter to filter the surgical materials in the bottle 10. That is, impurities in the surgical materials can pass through the filter, so that the pathological specimens and impurities in the surgical materials can be separated. The negative pressure device can draw in the surgical materials from the bottle 10 through the second tube 22 to remove the impurities in the surgical materials from the bottle 10, so that the pathological specimens in the surgical materials can be retained in the bottle 10.

[0035] On the one hand, it can prevent impurities from contaminating pathological specimens and improve the examination results of pathological examinations. On the other hand, by separating the first cap 20 from the bottle 10, the bottle 10 and the pathological specimen can be transported together, which is convenient for operation. Compared with the method of medical staff cutting open the bottle 10 to pick out the pathological specimen from the impurities, it can prevent the pathological specimen and impurities from being completely exposed to the outside world, reduce the risk of infection for medical staff, reduce the workload of medical staff, reduce the difficulty of collecting and transporting pathological specimens, improve the efficiency of surgical cooperation, shorten the overall surgical time, and thus reduce the safety risks of surgery.

[0036] Understandably, the pathology collection device also includes two suction connectors (not shown in the figure), one of which can be attached to the other end of the first tube 21 (e.g., Figure 3 The rear end shown allows the other end of the first tube 21 to be connected to the tubing on the operating table via a suction connector. This allows the bottle 10 to aspirate intraoperative material from the operating table through the first tube 21, and also improves the sealing of the connection between the first tube 21 and the tubing on the operating table. This prevents air leakage from the pathology collection device during operation, ensures the working effect of the negative pressure component, and prevents leakage of intraoperative material, thereby improving the reliability and stability of the pathology collection device.

[0037] Another suction connector can be installed at the other end of the second tube 22 (e.g.) Figure 3 The front end shown allows the other end of the second tube 22 to be connected to the tubing on the negative pressure component via a suction connector. This allows the negative pressure component to suction impurities from the bottle 10 through the second tube 22, and also improves the sealing of the connection between the second tube 22 and the negative pressure component tubing. This prevents air leakage from the pathology collection device during operation, ensures the effectiveness of the negative pressure component, prevents leakage of materials during surgery, and improves the reliability and stability of the pathology collection device.

[0038] According to the embodiments of the present invention, the pathological collection device for the operating table, by setting a filter inside the bottle 10, can filter the intraoperative material inside the bottle 10, remove impurities from the intraoperative material from the bottle 10, and retain the pathological specimen inside the intraoperative material in the bottle 10, thereby preventing impurities from contaminating the pathological specimen, improving the examination effect of pathological examination, and by setting a first cap 20 that can be detachably connected to the bottle 10, it is convenient to remove the pathological specimen inside the bottle 10, and can prevent the pathological specimen and impurities from being completely exposed to the outside world, thereby reducing the risk of infection for medical staff, reducing the workload of medical staff, reducing the difficulty of collecting and transporting pathological specimens, improving the efficiency of surgical cooperation, shortening the overall operation time, and thus reducing the safety risks of surgery.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, according to some embodiments of the present invention, the filter element can be a filter partition 13, which can divide the receiving cavity 11 into a receiving cavity 111 and a filter cavity 112. The filter cavity 112 and the receiving cavity 111 can be located on opposite sides of the filter partition 13 (e.g., Figure 3 (as shown on the front and back sides), and the receiving cavity 111 and the filtering cavity 112 can be connected to the outside through the bottle mouth 12, which facilitates the removal of intraoperative materials in the bottle body 10 and facilitates the insertion of the first tube 21 and the second tube 22.

[0040] One end of the first tube 21 (e.g.) Figure 3 The lower end shown can extend into the receiving cavity 111, and one end of the second tube 22 (as shown) Figure 3 The lower end shown can extend into the filter chamber 112. The filter baffle 13 can have at least one filter port 131. The receiving chamber 111 and the filter chamber 112 can be connected through at least one filter port 131, which can achieve the filtration of intraoperative materials in the bottle 10. That is, impurities in the intraoperative materials can pass through the filter element, so that the pathological specimen and impurities in the intraoperative materials can be separated, which can prevent impurities from contaminating the pathological specimen and improve the examination effect of pathological examination.

[0041] Specifically, during the operation of the negative pressure device, the surgical materials on the operating table enter the receiving cavity 111 inside the bottle 10. Impurities in the surgical materials (such as microsurgical instruments) enter the filtering cavity 112 from the receiving cavity 111 through the filtering port 131 because their size is smaller than or equal to the size of the filtering port 131. Alternatively, impurities in the surgical materials (such as liquids) enter the filtering cavity 112 from the receiving cavity 111 through the filtering port 131 because of their high fluidity. Impurities in the filtering cavity 112 can leave the bottle 10 through the second tube 22. Pathological specimens in the surgical materials remain in the receiving cavity 111 because their size is larger than the filtering port 131. On the one hand, this can prevent impurities from contaminating the pathological specimens and improve the examination effect of pathological examination. On the other hand, it can prevent impurities from leaking and being exposed to the outside world, reduce the risk of infection for medical staff, and reduce the safety hazards of surgery.

[0042] like Figure 6As shown, in some embodiments, the filter port 131 can be a circular opening for easy processing. The diameter of the filter port 131 can be D (not shown in the figure). If the diameter of the filter port 131 is too large, the pathological specimen can easily enter the filter cavity 112 from the receiving cavity 111 through the filter port 131, affecting the filtration effect of intraoperative materials. Therefore, the diameter of the filter port 131 can be limited to less than or equal to 2 mm. For example, D can be any value of 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm or any value between two of them, as well as a value between 0 and 0.5 mm. This can improve the filtration effect of intraoperative materials, improve the collection effect of pathological specimens, and allow surgical instruments such as micro-brain cotton pads and cotton balls to be placed in the receiving cavity 111, thus enabling the collection of surgical instruments such as micro-brain cotton pads and cotton balls.

[0043] like Figure 6 As shown, in some embodiments, the filter port 131 can be a circular opening for easy processing. The diameter of the filter port 131 can be D (not shown in the figure). If the diameter of the filter port 131 is too large, the pathological specimen can easily enter the filter cavity 112 from the receiving cavity 111 through the filter port 131, affecting the filtration effect of intraoperative materials. Therefore, the diameter of the filter port 131 can be limited to less than or equal to 1 mm. For example, D can be any one of 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm or any range between two, and a range between 0 and 0.2 mm. This can improve the filtration effect of intraoperative materials, improve the collection effect of pathological specimens, and allow small pathological tissues such as stones and tissue debris to be retained in the receiving cavity 111, thus enabling the collection of small pathological tissues such as stones and tissue debris.

[0044] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the volume of the receiving cavity 111 can be V1 (not shown in the figure), and the volume of the filtering cavity 112 can be V2 (not shown in the figure). If the volume of the receiving cavity 111 is too small, the bottle 10 will have difficulty collecting the intraoperative material on the operating table, affecting the overall duration of the operation. If the volume of the filtering cavity 112 is too large, the negative pressure component will have difficulty completely extracting the impurities in the bottle 10, affecting the examination effect of the pathological examination.

[0045] Therefore, the volume of the receiving cavity 111 can be limited to a range greater than that of the filtering cavity 112, i.e., V1>V2. This allows the bottle 10 to completely collect intraoperative materials on the operating table, shortens the overall operation time, reduces the safety risks of the operation, and allows the negative pressure component to completely extract impurities from the bottle 10. This improves the filtration effect of intraoperative materials in the bottle 10, prevents impurities from contaminating pathological specimens, and improves the examination effect of pathological examination.

[0046] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the filter partition 13 and the bottle body 10 are integrally formed, which is convenient for processing and can improve the structural strength of the entire bottle body 10. It is understood that both the filter partition 13 and the bottle body 10 can be made of heat-resistant polypropylene (PP) material, which can ensure the structural strength of the filter partition 13, ensure the service life of the filter partition 13, reduce its impact on pathological specimens, and ensure the examination effect of pathological examination.

[0047] According to some embodiments of this utility model, the bottle body 10 can be a transparent part. For example, the bottle body 10 can be made of transparent materials such as acrylic (PMMA) or polypropylene (PP), which can ensure the structural strength of the bottle body 10, ensure the service life of the bottle body 10, and facilitate medical staff to observe the condition of the intraoperative substances in the bottle body 10, thereby reducing the safety risks of surgery.

[0048] like Figure 3 , Figure 6 and Figure 7 As shown, according to some embodiments of the present invention, one end of the first tube 21 (e.g.) Figure 3 The distance between the lower end shown and the bottom wall of the bottle 10 is L1, and one end of the second tube 22 (as shown) Figure 3 The distance between the lower end of the first tube 21 and the bottom wall of the bottle 10 is L2. If the distance between one end of the first tube 21 and the bottom wall of the bottle 10 is too small, once the intraoperative material in the bottle 10 has passed the first end of the first tube 21, the bottle 10 will have difficulty continuing to aspirate the intraoperative material on the operating table through the first tube 21. If the distance between one end of the second tube 22 and the bottom wall of the bottle 10 is too large, the negative pressure component will have difficulty aspirating impurities into the filter chamber 112 through the second tube 22.

[0049] Therefore, the distance between one end of the first tube 21 and the bottom wall of the bottle 10 can be limited to a range greater than the distance between one end of the second tube 22 and the bottom wall of the bottle 10, i.e., L1>L2. This ensures that the bottle 10 can smoothly aspirate intraoperative materials on the operating table through the first tube 21, and also ensures that the negative pressure component can smoothly extract impurities from the bottle 10 through the second tube 22. On the one hand, this ensures the filtration effect of intraoperative materials in the bottle 10, prevents impurities from contaminating pathological specimens, and improves the examination effect of pathological examination. On the other hand, it prevents impurities from leaking and being exposed to the outside world, reduces the risk of infection for medical staff, and reduces the safety hazards of surgery.

[0050] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the first cap 20 and the bottle 10 can be threaded together, which can improve the connection effect between the first cap 20 and the bottle 10, improve the sealing of the receiving cavity 11 when the bottle mouth 12 is closed by the first cap 20, prevent the leakage of intraoperative substances in the bottle 10 or direct exposure to the outside world, reduce the infection risk of medical staff, reduce the safety hazards of surgery, and facilitate operation.

[0051] like Figure 1 , Figure 2 and Figure 4 As shown, according to some embodiments of the present invention, the collection bottle 100 may further include a second cap 30. The collection bottle 100 may have a first state and a second state. In the first state, the first cap 20 and the bottle body 10 may be connected to close the bottle mouth 12, and the second cap 30 and the bottle body 10 may be detached. At this time, the bottle body 10 may collect intraoperative materials on the operating table and filter them to retain the pathological specimens in the intraoperative materials in the bottle body 10, thereby realizing the collection of pathological specimens.

[0052] In the second state, the first cap 20 and the bottle 10 can be detached, and the second cap 30 and the bottle 10 can be connected to close the bottle opening 12, which can seal the receiving cavity 11, facilitate the transport of the bottle 10 and the pathological specimen together, prevent the pathological specimen in the bottle 10 from leaking or being directly exposed to the outside, improve the collection effect of pathological specimens, improve the examination effect of pathological examination, reduce the infection risk of medical staff, and reduce the safety risks of surgery.

[0053] like Figure 1 and Figure 4As shown, in some embodiments, the second cap 30 and the bottle 10 are threaded together, which can improve the connection effect between the second cap 30 and the bottle 10, improve the sealing of the receiving cavity 11 when the bottle mouth 12 is closed by the second cap 30, prevent the pathological specimen in the bottle 10 from leaking or being directly exposed to the outside world, improve the examination effect of pathological examination, reduce the infection risk of medical staff, reduce the safety risks of surgery, and facilitate operation.

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the first cap 20 is provided with a first tube 21 and a second tube 22. Before surgery, medical staff can tighten the bottle 10 and the first cap 20. One end of the first tube 21 extends into the bottle 10, and the other end of the first tube 21 is connected to the operating table. One end of the second tube 22 extends into the bottle 10, and the other end of the second tube 22 is connected to the negative pressure device. When the negative pressure device is working, it can draw the intraoperative material on the operating table into the bottle 10. The bottle 10 is provided with a filter. The filter can separate the pathological specimen and impurities in the intraoperative material during the operation of the negative pressure device. The negative pressure device can draw the impurities out of the bottle 10 so that the pathological specimen is left in the bottle 10.

[0055] At the end of the procedure, medical staff can unscrew bottle 10 from the first cap 20 and tighten bottle 10 and the second cap 30 to seal the pathological specimen. This facilitates the transport of bottle 10 and the pathological specimen together, prevents leakage of the pathological specimen inside bottle 10 or direct exposure to the outside world, improves the collection efficiency of pathological specimens, enhances the examination results of pathological examinations, reduces the risk of infection for medical staff, and minimizes the safety risks of the procedure.
