[0048] Specifically, a hysteroscope specimen collector provided by the present utility model includes a collection box 1, a flow regulating valve 2, and a bottom cover 3. The collection box 1 includes a connection cover 11, a box body 12, and an input connector 13. During use, the suction head of the hysteroscope is detachably connected to the input connector 13, and at the same time, the output connector 31 is detachably connected to a negative pressure device. This detachable connection can be in the form of plugging, strap connection, friction connection, or other ways that can firmly connect the suction head of the hysteroscope to the input connector 13. At this time, the negative pressure device is turned on, and the hysteroscope specimen and the pre-added physiological saline for rinsing are sucked into the collector through the suction head of the hysteroscope. Due to the setting of the filter net 111, the hysteroscope specimen remains in the specimen collection cavity formed by the enclosure of the connection cover 11 and the box body 12, and the physiological saline passes through the filter net 111 and remains in the filtrate recovery cavity with the flow regulating valve 2, and is gradually recovered by the negative pressure device. During the suction of the hysteroscope specimen, the flow regulating valve 2 can be used to adjust the flow aperture, control the suction intensity of the hysteroscope specimen and the physiological saline, facilitate the operator to change the suction progress according to the size, position distribution of the hysteroscope specimen or other clinical factors during the operation, making the operation of the suction process more operable and improving the work efficiency of the operator. In this way, an integrated hysteroscope specimen collector that is convenient for clinical specimen collection and operator operation is constructed, reducing the difficulty of collecting hysteroscope specimens and the probability of intraoperative instrument contamination.

[0053] In some possible implementation manners, each shunt hole group 212 includes a high-flow column, a medium-flow column, and a low-flow column, and the high-flow column, the medium-flow column, and the low-flow column are sequentially arranged adjacent to each other around the first direct current hole 211; Among them, a number of large holes are opened in the high-flow column, a number of medium holes are opened in the medium-flow column, and a number of small holes are opened in the low-flow column, and the diameters of the large holes, the medium holes, and the small holes decrease in sequence.

[0054] Specifically, as Figure 5 shown, each shunt hole group 212 includes a high-flow column, a medium-flow column, and a low-flow column, and by changing the aperture sizes of the flow holes respectively opened in the high-flow column, the medium-flow column, and the low-flow column, the flow rates among the high-flow column, the medium-flow column, and the low-flow column decrease in sequence, forming three flow rate gears.

[0055] In some possible embodiments, the size of each cylindrical throttle hole 222 is adapted to the size of any high-flow column, medium-flow column, and low-flow column; the interval angle between two adjacent cylindrical throttle holes 222 is the same as the interval angle between two adjacent high-flow columns.

[0056] Specifically, as Figure 6 shown, the size of the cylindrical throttle hole 222 is adapted to the size of any high-flow column, medium-flow column, and low-flow column. By rotating the adjusting piece 22, the four cylindrical throttle holes 222 are correspondingly overlapped with four high-flow columns, or four medium-flow columns, or four low-flow columns, thereby changing the flow aperture passing through the cylindrical throttle holes 222.

[0057] In some possible embodiments, the connecting cover 11 includes an annular base 112, and the filter net 111 is arranged in the hollow part of the annular base 112; one end of the annular base 112 is detachably connected to the box body 12, and the other end of the annular base 112 is connected to the outer edge 213.

[0058] Specifically, as Figure 2 shown, the filter net 111 is arranged in the hollow part of the annular base 112. As an implementable way, the middle part of the annular base 112 is detachable, and the filter net 111 can be fixed to the middle part of the annular base 112 by means of snap connection or bonding, thereby realizing the functions of disassembling and replacing the filter net 111 and realizing the repeated use of the hysteroscope specimen collector.

[0059] In some possible embodiments, the size of the filter net 111 is adapted to the size of the fixing piece 21.

[0060] In some possible embodiments, an external thread is provided on the outer edge of the connecting cover 11, and an internal thread adapted to the external thread is provided on the inner wall of the box body 12, and the internal thread is in threaded engagement with the external thread.

[0061] Specifically, as Figure 2 shown, the connection stability between the connecting cover 11 and the box body 12 is improved through threaded engagement, and it is avoided that the connecting cover 11 and the box body 12 are separated during the suction process, causing the hysteroscope specimen to flow out.

[0062] In some possible embodiments, a flap-shaped barrier film 14 is provided at the connection between the input joint 13 and the box body 12, so that the suction head of the hysteroscope passes through the flap-shaped barrier film 14 and is connected to the specimen collection cavity.

[0063] Specifically, as Figure 3 shown, through the setting of the flap-shaped barrier film 14, it is avoided that when the suction head of the hysteroscope is removed after the suction process ends, the fine tissues of the hysteroscope specimen flow out through the input joint 13, avoiding specimen missed inspection.

[0064] In some possible embodiments, the flap-shaped barrier film 14 is made of silicone material.

[0065] Specifically, using silicone material can avoid the growth of bacteria and facilitate cleaning and maintenance.
