[0047] Example 1

[0048] See also Figure 1-3Specifically, in an embodiment of the specimen collection device, the specimen collection device provided by the present application is used for collecting pathological specimens in arthroscopic surgery, and specifically includes an upper cylinder 1, a lower cylinder 2 and a filter assembly 3. A planer connecting tube head 11 is provided at the top edge of the upper cylinder 1; the lower cylinder 2 is detachably connected to the upper cylinder 1, and the upper cylinder 1 and the lower cylinder 2 are connected to form a sealed pathological specimen collection cavity, and a negative pressure connecting tube head is provided on the lower cylinder 2; the filter assembly 3 is provided at the top opening of the lower cylinder 2 and is detachably connected to the lower cylinder 2.

[0049] Specifically, an embodiment of the present invention provides a specimen collection device, comprising an upper cylinder 1, a lower cylinder 2 and a filter assembly 3, wherein a planer connection pipe head 11 is provided at the top edge of the upper cylinder 1; the lower cylinder 2 is detachably connected to the upper cylinder 1, and the upper cylinder 1 and the lower cylinder 2 are connected to form a sealed pathological specimen collection chamber, and a negative pressure connection pipe head is provided on the lower cylinder 2; the filter assembly 3 is provided at the top opening of the lower cylinder 2 and is detachably connected to the lower cylinder 2. The embodiment of the present application realizes the collection of solid pathological specimens through the filter assembly 3 by providing the filter assembly 3, and by providing the upper cylinder 1 and the lower cylinder 2 to be detachably connected, and detachably providing the filter assembly 3 at the cylinder mouth of the lower cylinder 2, so as to facilitate the removal of the pathological specimens collected by the filter assembly 3, thereby achieving the technical effect of improving the convenience of collecting and removing pathological specimens generated during surgery. The present application has a simple structure and low production cost.

[0050] In a possible embodiment, the specimen collection device further includes a hanging component 4 , which is disposed at the top center of the upper cylinder 1 , so that the specimen collection device can be hung on the operating table through the hanging component 4 .

[0051] In one possible embodiment, the upper cylinder 1 is threadedly connected to the lower cylinder 2. An internal thread is provided on the inner side wall of the bottom opening of the upper cylinder 1, and an external thread is provided on the outer side wall of the top of the lower cylinder 2. The internal thread of the upper cylinder 1 is adapted to the external thread of the lower cylinder 2.

[0052] As a feasible method, a circular connecting piece can be sleeved on the outer side wall of the bottom of the upper cylinder 1. The connecting piece can slide relative to the upper cylinder 1. A limiting portion is provided on the outer side wall of the bottom of the upper cylinder 1 to limit the connecting piece and prevent it from sliding out of the upper cylinder 1. The connecting piece is then threadedly connected to the lower cylinder 2.

[0053] In one possible embodiment, the hanging assembly 4 includes a hook body and a self-locking member. The bottom end of the hook body is fixedly connected to the top center of the upper cylinder 1. A through slot is defined in the middle of the hook body and extends along the length of the hook body. The self-locking member is located within the through slot and hingedly connected to the sidewalls of the through slot. When the hook body is hung, the self-locking member is rotated to lock the hook body. This prevents the hook from falling off when the specimen collection device of the present application is hung on an operating table via the hanging assembly 4.

[0054] In one possible implementation, Figure 3 As shown, the filter assembly 3 includes an outer frame 31, a filter screen 32, and a cylindrical side wall 33. The outer diameter of the outer frame 31 is adapted to the inner diameter of the lower cylinder 2; the filter screen 32 is arranged in the middle of the outer frame 31, and the filter screen 32 is expanded relative to the outer frame 31 to form a hemispherical filtering area; the bottom edge of the cylindrical side wall 33 is fixedly connected to the outer frame 31, and the outer diameter of the cylindrical side wall 33 is adapted to the inner diameter of the lower cylinder 2. The top edge of the cylindrical side wall 33 is formed outward with a circle of flange 34, and the outer diameter of the flange 34 is larger than the inner diameter of the lower cylinder 2, and is less than or equal to the outer diameter of the lower cylinder 2. The filter assembly 3 is hung on the top edge of the lower cylinder 2 through the flange 34.

[0055] Specifically, when the filter assembly 3 is placed at the opening of the lower barrel 2, the cylindrical sidewall 33, outer frame 31, and filter screen 32 enter the cavity of the lower barrel 2. Simultaneously, the flange 34 is positioned exactly at the edge of the barrel opening of the lower barrel 2, thereby limiting the position of the filter assembly 3. The filter screen 32 expands relative to the outer frame 31 to form a hemispherical filter area, thereby expanding the filtration area. The filter screen 32 can be a metal filter screen 32 or a gauze filter screen 32.

[0056] In a possible embodiment, the negative pressure connecting pipe head includes a first negative pressure connecting pipe head 21 and a second negative pressure connecting pipe head 22. The first negative pressure connecting pipe head 21 is arranged at the bottom center of the lower cylinder 2, and the second negative pressure connecting pipe head 22 is arranged on the side wall of the lower cylinder 2.

[0057] Specifically, the first negative pressure connecting tube head 21 is connected to an external negative pressure aspirator to collect only solid pathological specimens; or the second negative pressure connecting tube head 22 is connected to the negative pressure aspirator to collect both liquid and solid pathological specimens. Furthermore, the corresponding negative pressure connecting tube head can be selected to connect to the negative pressure aspirator to meet different pathological specimen collection requirements, such as collecting only solid pathological specimens, only liquid pathological specimens, or both solid and liquid pathological specimens.

[0058] In one possible embodiment, the inner diameter of the planer connecting pipe head 11 gradually decreases in the direction away from the upper cylinder 1; the inner diameters of the first negative pressure connecting pipe head 21 and the second negative pressure connecting pipe head 22 gradually decrease in the direction away from the lower cylinder 2 to facilitate connection with the planer, the negative pressure suction device and the pipelines thereon.

[0059] In one possible embodiment, the planer connecting tube head 11, the first negative pressure connecting tube head 21, and the second negative pressure connecting tube head 22 are each provided with a corresponding rubber sealing cap 5. When not in use, the corresponding connecting tube head is sealed with the rubber sealing cap 5 to prevent external impurities from entering. At the same time, when using the device, since the first negative pressure connecting tube head 21 and the second negative pressure connecting tube head 22 cannot be used at the same time, that is, when only solid pathological specimens need to be collected, the planer connecting tube head 11 can be connected to the planer, the first negative pressure connecting tube head 21 can be connected to the negative pressure suction tube, and the second negative pressure connecting tube head 22 can be sealed with the rubber sealing cap 5;

[0060] When only liquid pathological specimens need to be collected or both liquid and solid pathological specimens need to be collected, the planer connecting pipe head 11 can be connected to the planer, the second negative pressure connecting pipe head 22 can be connected to the negative pressure suction tube, and the first negative pressure connecting pipe head 21 can be sealed with a rubber sealing cap 5.

[0061] Generally, the demand for collecting liquid pathology specimens is less than that for collecting solid pathology specimens. When only solid pathology specimens need to be collected, if the planer connecting pipe head 11 is connected to the planer and the second negative pressure connecting pipe head 22 is connected to the negative pressure suction tube, both liquid and solid pathology specimens are collected at the same time. Therefore, additional processing is required for the unnecessary liquid pathology specimens, which increases the complexity of the operation and also increases the hanging burden. Therefore, the present application provides a first negative pressure connecting pipe head 21 and a second negative pressure connecting pipe head 22 to meet different sampling needs.

[0062] In a possible implementation manner, the upper cylinder 1, the lower cylinder 2, and the suspension assembly 4 are all made of polyethylene material to reduce the production cost.

[0063] In a possible embodiment, since the specimen collection device of the present application is connected between the planer and the negative pressure aspirator, it needs to be able to withstand a negative pressure of 0.04 to 0.06 MPa. Therefore, the side wall thickness of the upper cylinder 1 and the lower cylinder 2 needs to be set to at least 3 mm to avoid deformation of the upper cylinder 1 and the lower cylinder 2 under negative pressure. At the same time, the diameter of the upper cylinder 1 and the lower cylinder 2 is set to at least 9 cm. To avoid clogging of the cylinder. In order to ensure the amount of liquid specimens retained, the volume of the liquid pathology specimen that the lower cylinder can retain is at least 50 ml, so the liquid storage volume between the setting position of the second negative pressure connecting tube head 22 and the bottom of the lower cylinder is at least 50 ml.

[0064] It should be noted that the standard collection device provided by the present invention is a disposable product and should be avoided from repeated use.
