[0034] Existing biopsy tissue collectors for collecting breast or thyroid tissues are generally directly mounted on a biopsy handle, which is not light enough. In addition, if the biopsy handle needs to be wrapped with a sterile cover for aseptic operation, the biopsy tissue collector will also be wrapped, resulting in obstacles to the removal of tissues, which is not conducive to collaborative surgery by multiple people.
[0035] Based on this, the utility model proposes a biopsy tissue collector, which is arranged on the outside of the biopsy tissue through an injection pipeline interface, which is conducive to reducing the weight of the biopsy handle; in addition, when performing sterile packaging, sterile gloves will not wrap the biopsy tissue collector, and will not hinder the removal of the biopsy tissue in the bin. This solution is convenient for users to collect biopsy tissues and is also conducive to collaborative surgery by multiple people.
[0036] like Figure 1 - Figure 4 As shown, the biopsy tissue collector comprises:
[0037] The box body 100 has an open cavity formed inside, and the box body 100 is provided with a sample injection line interface 110 and a negative pressure line interface 120 both connected to the cavity; and
[0038] The warehouse body 200 is detachably arranged in the cavity through the opening. The warehouse body 200 has a sealing portion for sealing the opening. A tissue collection cavity is formed inside the warehouse body 200. The warehouse body 200 has a collection port 221 for sampling. The collection port 221 connects the cavity and the tissue collection cavity. A filtering structure is arranged on the warehouse body 200, and the filtering structure connects the cavity and the tissue collection cavity.
[0039] In the technical solution adopted in this embodiment, the biopsy tissue collector includes a box body 100 and a bin body 200. The box body 100 is connected to the biopsy handle through the sampling pipeline interface 110, and is connected to the external negative pressure generator through the negative pressure pipeline interface 120. A bin body 200 is detachably provided in the cavity inside the box body 100, and a tissue collection cavity is formed inside the bin body 200 for storing biopsy tissue. The bin body 200 is provided with a collection port 221 connected to the sampling pipeline interface 110, and the bin body 200 is provided with a filtering structure, which can connect the tissue collection cavity with the cavity. In this way, under the action of the negative pressure generated by the negative pressure generator, the removed biopsy tissue enters the cavity from the biopsy sampling device through the sampling pipeline interface 110, and then enters the tissue collection cavity through the collection port 221, thereby realizing the collection of biopsy tissue, and the blood or tissue fluid entering the tissue collection cavity with the tissue enters the cavity through the filtering structure, and is discharged along the corresponding negative pressure pipeline under the action of negative pressure. The biopsy tissue collector in this solution is arranged on the outside of the biopsy handle through the sample injection line interface 110, which is beneficial to reduce the weight of the biopsy handle; in addition, when performing sterile packaging, sterile gloves will not wrap the biopsy tissue collector, and will not hinder the removal of the biopsy tissue in the bin body 200. This solution is convenient for users to collect biopsy tissues and is also conducive to collaborative surgery by multiple people.
[0040] Specifically, the biopsy tissue collector can be used for the collection of various biopsy tissues, such as breast tissue, thyroid tissue, etc. Optionally, the box body 100 is made of a transparent material, which is convenient for the user to observe whether there is any biopsy tissue missing from the cavity or stuck at the collection port 221. Furthermore, the bin body 200 can also be made of a transparent material, which is convenient for the user to observe in time whether the tissue collection cavity is full of biopsy tissue. When it is observed that the biopsy tissue is full, the opening needs to be opened, and the bin body 200 is taken out to empty the biopsy tissue and then put into the cavity for the next collection. It should be noted that there is no specific limitation on the detachable connection method of the bin body 200, for example, it can be a snap-on connection, or a threaded connection, etc.
[0041] It is worth mentioning that the sample introduction line interface 110 and the negative pressure line interface 120 on the box body 100 are arranged opposite to each other, so that the biopsy tissue can be sucked more smoothly by using the negative pressure. It should be pointed out that the biopsy tissue collector can be set at any position of the vacuum tube on the biopsy sampling device to reduce the weight of the handle of the biopsy sampling device, which can ensure smooth sampling during sterile operation and facilitate multi-person collaborative surgery.
[0042] Alternatively, if Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment of the utility model, the box body 100 is also connected with a negative pressure tube and a sample injection tube, wherein the sample injection line interface 110 is formed at the end of the sample injection tube for connection with the sample injection tube, and the negative pressure line interface 120 is formed at the end of the negative pressure tube for connection with the negative pressure tube, so that the biopsy tissue collector can be conveniently connected and fixed to the external biopsy handle and the negative pressure generator respectively. In a possible implementation, the sample injection tube and the negative pressure tube are both integrated with the box body 100. In this way, the number of parts and components can be reduced, the assembly process can be reduced, and the parts that need to be sealed can also be reduced.
[0043] Alternatively, if Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the injection line interface 110 further includes at least one first positioning protruding ring 111 protruding from the outer wall of the injection tube; the negative pressure line interface 120 includes at least one second positioning protruding ring 121 protruding from the outer wall of the injection tube. With this structure, the injection line interface 110 and the negative pressure line interface 120 can be directly connected to a low-cost elastic hose (for example, a rubber hose), and the corresponding positioning protruding ring can play a positioning role to prevent the elastic hose from loosening.
[0044] It should be noted that there is no specific limitation on the shapes of the first positioning protruding ring 111 and the second positioning protruding ring 121. For example, the cross-section of the protruding ring can be triangular or square, etc., as long as it is a positioning structure that is conducive to connection.
[0045] Optionally, in an embodiment of the present utility model, the warehouse body 200 includes:
[0046] A box cover 210, a sealing portion is formed on the box cover 210, and the box cover 210 is detachably connected to the box body 100 to open or close the opening; and
[0047] The inner liner 220 is integrally arranged on the box cover 210 , and the collecting port 221 and the filtering structure are both arranged on the inner liner 220 .
[0048] Specifically, in order to remove the chamber body 200 from the cavity, the chamber body 200 includes a box cover 210 and an inner liner 220, wherein the box cover 210 and the chamber body 100 are detachably connected, and the detachable connection of the box cover 210 can be used to open or close the opening; and, in order to facilitate the removal of the inner liner 220, the inner liner 220 and the box cover 210 are integrally arranged, and in this embodiment, the inner liner 220 and the box cover 210 can be fixed on the box cover 210 by fasteners or other connectors, and the two can also adopt an integrated molding process, which can reduce the number of parts and simplify the manufacturing process, on the one hand, can reduce the number of operating steps required for assembly; on the other hand, can reduce the parts that need to be sealed. In this way, when it is necessary to remove the inner liner 220, it is only necessary to separate the box cover 210 from the chamber body 100 to take the box cover 210, which can avoid the problem of contamination of the biopsy tissue when the user removes the inner liner 220 alone, and can also facilitate the user's operation.
[0049] Alternatively, if Figure 2 As shown, in one embodiment of the utility model, in order to facilitate the separation of the box cover 210 and the box body 100, the box cover 210 and the box body 100 adopt a snap-on connection method. In one embodiment of the utility model, the box cover 210 and the box body 100 adopt a snap-on connection method in which a buckle and a slot cooperate, one of the box body 100 and the box cover 210 is provided with a buckle, and the other of the box body 100 and the box cover 210 is provided with a slot. Specifically, when it is necessary to open the box cover 210 to take out the liner 220, the button on the box cover 210 can be pressed to disengage the buckle from the slot, and the box cover 210 can be pulled in a direction away from the box body 100; when the liner 220 needs to be placed in the cavity, the box cover 210 can be pressed so that the buckle is accurately buckled into the inside of the slot and can be used again. In this way, through the mutual cooperation of the buckle and the slot, the box body 100 and the box cover 210 can be easily snap-on and fixed, thereby simplifying the process of taking and placing the liner 220.
[0050] Optionally, in some other embodiments of the present invention, the warehouse body 200 includes:
[0051] The box cover 210 is integrally provided on the box body 100, the blocking portion is formed on the box cover 210, and the box cover 210 opens or blocks the opening by opening and closing; and
[0052] The inner liner 220 is detachably disposed in the cavity, and the collecting port 221 and the filtering structure are both disposed on the inner liner 220 .
[0053] In this structure, the box cover 210 and the box body 100 are integrally arranged, and the inner liner 220 is detachably arranged in the cavity, so that the inner liner 220 can be taken out from the opening by opening the box cover 210, and the box body 200 can be removed from the cavity through the opening. In this way, when the filter holes of the filter structure on the inner liner 220 are blocked by the biopsy tissue or when the tissue needs to be removed, the inner liner 220 can be easily taken out for cleaning or directly replaced.
[0054] Alternatively, if Figure 2 and Figure 3 As shown, in one embodiment of the utility model, in order to improve the sealing property of the cavity during the collection process, the biopsy tissue collector further includes a sealing member 300, which can be arranged on the box cover 210 or the box body 100. When the box cover 210 covers the box body 100, the sealing member 300 is compressed and seals the gap between the box body 100 and the sealing portion of the box cover 210, thereby sealing the cavity. In this embodiment, the sealing portion of the box cover 210 and the sealing member 300 are used in combination to seal the cavity, effectively improving the sealing property inside the cavity.
[0055] Alternatively, if Figure 2 and Figure 3 As shown, in one embodiment of the utility model, the box cover 210 has an extension portion extending into the cavity, which is the blocking portion, and the sealing member 300 is sleeved on the outer periphery, and the outer edge of the sealing member 300 abuts against the cavity wall of the cavity. The sealing member 300 is squeezed between the box cover 210 and the box body 100, so that the cavity is sealed to form a sealed cavity, thereby ensuring the sealing property during the biopsy tissue collection process.
[0056] Alternatively, if Figure 2 As shown, in one embodiment of the utility model, in order to form a negative pressure inside the inner liner 220, the filter structure includes a plurality of filter holes arranged on the chamber body 200, and the filter holes can connect the tissue collection chamber and the cavity to ensure that the biopsy tissue can be smoothly sucked into the tissue collection chamber by using the negative pressure. On the other hand, when collecting the biopsy tissue, in addition to the solid biopsy tissue, some liquid tissues such as body fluids and blood may also be collected from the injection line interface 110, and some liquid tissues may enter the gap between the inner liner 220 and the box body 100. Under the action of negative pressure, the above liquid tissues can enter the negative pressure line interface 120 through the filter holes and then be drawn out. It should be noted that the specific shape and number of the filter holes can be adjusted and designed as needed to meet the functional requirements, and are not limited here.
[0057] The utility model also provides a biopsy system, which includes a biopsy handle, a negative pressure generator and a biopsy tissue collector, wherein the injection line interface 110 is connected to the biopsy handle through a first line, and the negative pressure line interface 120 is connected to the negative pressure generator through a second line.
