Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary equipment, and more specifically, to a novel tumor specimen collection device. Background Art

[0002] All surgeries and procedures in surgical departments, and even some internal medicine departments, involve the process of obtaining tumor specimens. While specimens are relatively easy to collect for en bloc resections, they are often lost by suction for piecemeal resections. The current trend in surgical procedures is towards endoscopic and minimally invasive procedures. For tumors that can be resected piecemeal, methods such as piecemeal resection and intratumoral volume reduction are often employed. Therefore, there is a constant risk of accidental aspiration of the tumor. However, tumor specimens are crucial for subsequent pathological diagnosis and other processes. Furthermore, some patients may have very small tumors, making each specimen invaluable. Accidental aspiration can severely impact subsequent diagnosis and treatment. Utility Model Content

[0003] One purpose of the present invention is to provide a new technical solution for a novel tumor specimen collection device to solve the problems in the above-mentioned background technology.

[0004] According to a first aspect of the present utility model, a novel tumor specimen collection device is provided, comprising a collector and a diverter;

[0005] The upper end of the collector is fixed with a liquid inlet pipe, the lower end is fixed with a liquid outlet pipe, and the interior of the collector is provided with a filter screen;

[0006] The diverter includes a main pipeline and at least two diverter pipes, and the diverter pipes are connected to the liquid inlet pipe or the liquid outlet pipe of the collector; at least two independent diverter holes are opened at the bottom of the main pipeline, and the diverter pipes are connected to the diverter holes one by one. A rotating shaft is provided between the diverter holes, and a diverter plate is rotatably connected to the rotating shaft. A through hole is provided on the diverter plate, and by rotating the diverter plate, the through hole can be connected to any one of the diverter holes.

[0007] Optionally, according to the new tumor specimen collection device described in the present invention, the collector includes an upper frame and a lower frame, the upper frame and the lower frame are connected by threads, the filter is clamped at the connection between the upper frame and the lower frame, the liquid inlet pipe is connected to the upper frame, and the liquid outlet pipe is connected to the lower frame.

[0008] Optionally, according to the novel tumor specimen collection device of the present invention, the upper frame is provided with an external thread, the lower frame is provided with an internal thread, and the upper frame is screwed into the interior of the lower frame.

[0009] Optionally, according to the new tumor specimen collection device described in the present invention, the lower frame is located at the bottom of the internal thread and shrinks inward to form a receiving plane. A receiving ring is provided on the peripheral side of the filter screen, and the receiving ring is overlapped on the receiving plane. When the upper frame is screwed into the lower frame, the receiving ring can be clamped.

[0010] Optionally, according to the novel tumor specimen collection device of the present invention, the inner sides of the upper frame and the lower frame, as well as the connection portions with the liquid inlet pipe and the liquid outlet pipe, respectively, are all in an arc-shaped structure.

[0011] Optionally, according to the novel tumor specimen collection device of the present invention, a toggle block is provided on the outer side of the diverter plate for driving the diverter plate to rotate.

[0012] Optionally, according to the novel tumor specimen collection device of the present invention, the toggle block is collinear with the center of the through hole and the circular hole of the diverter plate.

[0013] Optionally, according to the novel tumor specimen collection device of the present invention, the center of the through hole is located between the center of the toggle block and the center of the diverter plate.

[0014] The core element of this utility model is to connect a tumor specimen collector in series with an existing aspirator. Before tumor resection, the aforementioned toggle block can be rotated, driving the diverter plate to rotate, allowing all aspirated material to flow out of the shunt tube not connected to the tumor specimen collection device and directly into the waste collection bottle. This prevents non-tumor specimen solids from clogging the filter and increasing the difficulty of subsequent pathology specimen processing. During tumor resection, the aforementioned toggle block can be rotated, driving the diverter plate to rotate, allowing all aspirated material to enter the shunt tube connected to the tumor specimen collection device. All aspirated material during surgery first enters this collector, collecting solids such as the tumor specimen, while fluids and gases such as flushing fluid, blood, and tissue fluid continue to be drawn into the aspirator's waste collection bottle. During this period, a tumor specimen collector can be connected to another shunt tube. Once the collector's filter has collected enough solids, the filter mesh may become clogged, potentially affecting its efficiency in filtering liquids and solids. At this point, the collector can be replaced. The diverter ensures that the present application does not require disconnecting the aspirator, allowing replacement of the collector without disrupting the surgical procedure.

DETAILED DESCRIPTION

[0023] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0024] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0025] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0026] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0027] according to Figures 1 to 4 As shown, the utility model provides a novel tumor specimen collection device, including a collector and a diverter.

[0028] A liquid inlet pipe 3 is fixed at the upper end of the collector, a liquid outlet pipe 4 is fixed at the lower end, and a filter screen 7 is provided inside the collector.

[0029] The diverter includes a main pipeline 9 and at least two diverter pipes 10, which are connected to the liquid inlet pipe 3 or the liquid outlet pipe 4 of the collector, or directly connected to the distal drainage pipe; at least two independent diverter holes 15 are opened at the bottom of the main pipeline 9, and the diverter pipes 10 are connected one by one to the diverter holes 15. A rotating shaft 11 is provided between the diverter holes 15, and a diverter plate 12 is rotatably connected to the rotating shaft 11. The diverter plate 12 is provided with a through hole 13. By rotating the diverter plate 12, the through hole 13 can be connected to any one of the diverter holes 15.

[0030] The core element of this utility model is to connect a tumor specimen collector in series with an existing aspirator. All materials aspirated during surgery first enter this collector, collecting solid materials such as tumor specimens, while liquids and gases such as flushing fluid, blood, and tissue fluid continue to be drawn into the aspirator's waste liquid collection bottle. The diverter ensures that this application does not require disconnecting the aspirator, which would affect the surgical procedure before the collector is replaced. In other words, multiple collectors can be connected in series between the aspirator interface and the aspirator hose through a diverter. By rotating the diverter plate 12, one of the collectors is connected to the aspirator, thereby achieving the collection of tumor specimens. After the collector's filter screen has collected enough solids, the filter mesh may become clogged, affecting its efficiency in filtering liquids and solids. At this time, the collector can be replaced. By rotating the diverter plate 12, the aspirator is connected to another collector, and the full collector can be removed from the diverter without affecting the normal operation of the aspirator or the surgical procedure.

[0031] The collector further comprises an upper frame 1 and a lower frame 2, which are connected by threads. A filter screen 7 is snapped onto the connection between the upper frame 1 and the lower frame 2. A liquid inlet pipe 3 is connected to the upper frame 1, and a liquid outlet pipe 4 is connected to the lower frame 2. In this embodiment, the collector can be composed of a detachable upper frame 1 and lower frame 2, making it easier to remove the tumor specimen from the collector.

[0032] Furthermore, the upper frame 1 is provided with an external thread 5, and the lower frame 2 is provided with an internal thread 6, and the upper frame 1 is screwed into the interior of the lower frame 2. When implemented, the problem of liquid leakage from the gap between the upper frame 1 and the lower frame 2 can be effectively prevented.

[0033] Furthermore, the bottom of the lower frame 2, located at the inner thread 6, contracts inward to form a receiving surface. A receiving ring 8 is provided around the periphery of the filter 7. The receiving ring 8 overlaps the receiving surface and can clamp the receiving ring 8 when the upper frame 1 is screwed into the lower frame 2. During implementation, the receiving surface pre-positions the filter 7. When the upper frame 1 is gradually screwed into the lower frame 2, the upper frame 1 and the receiving surface clamp the receiving ring 8 of the filter 7, ensuring the stability of the filter 7.

[0034] Furthermore, the inner sides of the upper frame 1 and the lower frame 2, as well as the connections with the liquid inlet pipe 3 and the liquid outlet pipe 4 respectively, are all curved structures. The curved surface design is conducive to liquid flow and avoids liquid residue in the corners of the collector, which is not conducive to cleaning.

[0035] Furthermore, a toggle block 14 is provided on the outer side of the diverter plate 12 for driving the diverter plate 12 to rotate.

[0036] Furthermore, the toggle block 14 is collinear with the center of the through hole 13 and the circular hole of the diverter plate 12, and the center of the through hole 13 is located between the centers of the toggle block 14 and the diverter plate 12. In this embodiment, the position pointed by the toggle block 14 indicates that the through hole 13 is connected to the shunt tube 10 in that direction, which helps medical personnel intuitively identify which shunt tube 10 in the diverter is connected by the position of the toggle block 14.

[0037] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
