Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a tumor specimen collection device. Background Art

[0002] A tumor refers to a new organism formed by the proliferation of local tissue cells under the action of various tumorigenic factors. It is found that tumor cells will have metabolic changes different from normal cells, and at the same time, tumor cells themselves can adapt to the change of the metabolic environment through the conversion between glycolysis and oxidative phosphorylation. During the treatment of tumors, it is necessary to collect tumor specimens for observation, pathological detection, preservation, etc. Among them, tumor tissue specimens as research materials for malignant tumors play an important role in promoting the progress of tumor research.

[0003] During the existing surgical procedures, a suction device is often used to separate and aspirate tumors, and a collection cylinder is connected to the suction device to collect tumor tissues. A filter plate is provided in the collection cylinder to intercept the aspirated tumor tissues through the filter plate and separate the tumor tissues from body fluids. Then, a preservation solution is added to the collection cylinder to preserve the tumor tissue specimens. However, the existing tumor specimen collection devices have some deficiencies: in order to avoid the situation of insufficient tumor specimens in subsequent research, more samples are usually collected during collection. When taking samples, the tumor tissues on the filter plate are taken out one by one with a tumor forceps, and the operation is relatively cumbersome and the efficiency is low. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a tumor specimen collection device that can filter and collect tumor tissues, and the device is convenient to take out an appropriate amount of the collected specimens at one time when the tumor tissues need to be studied.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a tumor specimen collection device, including a collection cylinder and an end cap detachably connected to the upper end of the collection cylinder. An inhalation tube is provided at the upper end of the end cap, and an aspiration tube is provided at the lower end of the collection cylinder. A filtering part is provided in the collection cylinder. The filtering part includes a plurality of filter plates, and the plurality of filter plates enclose a disc having the same inner diameter as the collection cylinder. An operation bar is arranged vertically on each filter plate, the upper end of the operation bar extends out of the collection cylinder, and a fixing part for fixing the filter plate in the collection cylinder is provided on the operation bar.

[0006] Compared with the prior art, the beneficial effect of the present solution is that: when in use, the collection tube is connected to the pipe of the aspirator through the suction tube, so that the sucked tumor tissue and liquid flow into the collection tube, the tumor tissue is intercepted by the filter plate arranged inside the collection tube, and the liquid flows through the filter plate to the lower end of the collection tube and flows out of the collection tube through the suction tube. After sufficient tumor tissue is collected and the liquid flows out of the collection tube, the suction tube is sealed, and preservation liquid is added to the collection tube along the suction tube until the preservation liquid completely soaks the tumor tissue, and then the suction tube is sealed. When the tumor tissue needs to be removed and studied, the end cover is first opened, and then the filter plate is removed by moving the operation bar upward. The number of filter plates to be removed is determined according to the approximate number of tumor tissues required for each study. After a sufficient number of filter plates are removed, the end cover is closed to maintain a sealed and sterile environment in the collection tube. Compared with the traditional setting of a whole filter plate and taking tumor tissue by tumor removal forceps, the filter plate is separated into multiple and an operation bar is arranged on each filter plate, which is convenient for taking an appropriate amount of tumor tissue according to the specific needs of each study, and the operation is more convenient.

[0007] As a preferred embodiment of the utility model, along the axial direction of the collecting tube, each filter plate is provided with two partitions perpendicular to each other, each filter plate is provided with a baffle on one side that is in contact with the inner wall of the collecting tube, the outer sides of the partitions on two adjacent filter plates are in contact with each other, and the partition is provided with a grid for the circulation of the preservation liquid.

[0008] The beneficial effects of this solution are as follows: the partitions arranged on both sides of the filter plate can guide the enclosure of multiple filter plates, so that they can be more quickly enclosed to form a disc, which is easy to install; the two partitions and baffles arranged on the side of the filter plate form a barrier, which can ensure that when the operation strip is removed from the collection tube, the tumor tissue on the filter plate will not fall from the side of the filter plate, thereby avoiding waste of tumor tissue.

[0009] As a preferred embodiment of the utility model, a guide block is provided between the upper ends of the two partitions located on the same filter plate. The guide block is arranged in an upward convex arc shape. When multiple filter plates are combined to form a disc, multiple guide blocks are combined to form a part of a sphere, and its diameter is larger than the inner diameter of the suction pipe.

[0010] Advantages of this solution: When tumor tissues and body fluids flow through the aspirator into the collection cylinder, the falling tumor tissues first come into contact with multiple diversion blocks that enclose a partial spherical shape, and then slide along the arc of the diversion blocks into the filter plate. The diversion blocks play a buffering role for the falling tumor tissues. The diameter of the partial spherical shape enclosed by the multiple diversion blocks is larger than the diameter of the suction pipe, which can ensure that all the tumor tissues after falling can be led to the filter plate through the diversion pipe. At the same time, the diversion blocks provided between the two partition plates can also prevent the tumor tissues from colliding with the vertically arranged partition plates when entering the interior of the collection cylinder and damaging the tumor tissues, thus bringing inconvenience to the subsequent research on the tumor tissues.

[0011] As a preferred embodiment of the present utility model, a plurality of first card slots are provided along the circumferential direction of the upper side of the collection cylinder, and a second card slot is provided along the axial direction of each first card slot. The fixing portion includes a plurality of first card blocks arranged along the circumferential direction of the collection cylinder on the side of the operation bar close to the inner wall of the collection cylinder and a second card block arranged along the axial direction of the collection cylinder below the first card block. The first card block and the second card block are respectively clamped with the first card slot and the second card slot.

[0012] Advantages of this solution: By clamping the first card block into the first card slot to limit the operation bar in the vertical direction, thereby limiting the filter plate in the vertical direction, and by clamping the second card block into the second card slot to limit the operation bar in the horizontal direction, thereby limiting the filter plate in the horizontal direction, the filter plate can be firmly installed inside the collection cylinder. Moreover, the first card slot is provided on the upper side of the collection cylinder, which is convenient for directly moving the operation bar in the vertical direction to take out the tumor tissues.

[0013] As a preferred embodiment of the present utility model, the filtering portion further includes a support plate fixedly arranged inside the collection cylinder and fitting with its inner wall. The support plate is located below the filter plate and has a grid on the support plate. The lower side of each filter plate contacts the upper side of the support plate.

[0014] Advantages of this solution: The support plate provided on the lower side of the filter plate can support the filter plate, further ensuring the stability of the connection between the filter plate and the collection cylinder. Moreover, the support plate is provided with a grid, which can ensure that the body fluids other than the tumor tissues can smoothly pass through the support plate and flow out of the collection cylinder through the suction pipe.
