When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0038] Existing biopsy tissue collectors are generally directly mounted on puncture needles or biopsy sampling devices. When the collector is opened to obtain biopsy tissue, the collector connected to the biopsy device is usually in a non-sealed state, which can easily cause residual tissue fluid or blood in the collector to leak out, and the interior of the collector is easily contaminated by the external environment.

[0039] Based on this, the utility model proposes a biopsy tissue collector, in which a sealing cover is opened and closed on the box body, and the inner liner can be taken out from the box body. The sealing cover seals the opening on the cavity, so that negative pressure can be maintained in the cavity after the inner liner is taken out, which is beneficial to avoid foreign matter from entering the cavity during the process of opening the collector to obtain biopsy tissue, prevent the interior of the collector from being contaminated, and prevent the residual biopsy tissue in the collector from overflowing.

[0040] like Figure 1 - Figure 5 As shown, the biopsy tissue collector comprises:

[0041] The box body 100 has an open cavity formed inside, and the box body 100 is provided with an injection port 110 and a negative pressure port 120 both connected to the cavity;

[0042] The sealing cover 200 is openably disposed on the box body 100 to open or close the opening;

[0043] The inner liner 300 is detachably arranged in the cavity, and a collecting bin is formed inside the inner liner 300. The inner liner 300 is provided with a collecting port 310 connected to the collecting bin. The position of the collecting port 310 corresponds to the injection port 110, and the inner liner 300 is provided with a filtering structure connecting the collecting bin and the cavity.

[0044] In the technical solution adopted in this embodiment, the biopsy tissue collector includes a box body 100, a sealing cover 200 and an inner liner 300. When the biopsy tissue collector is applied to a biopsy system, the biopsy system includes a biopsy tissue sampling device, a negative pressure generating device and the tissue collector. The box body 100 is connected to a sampling channel of the biopsy tissue sampling device through a sampling port 110 (the biopsy tissue sampling device here can be, for example, a biopsy needle, then the sampling port 110 is connected to the sampling channel of the biopsy sampling needle), and is connected to an external negative pressure generating device through a negative pressure port 120; the inner liner 300 is detachably provided in the cavity inside the box body 100. , which is used to store biopsy tissues. A collecting bin is formed inside the inner liner 300. A collecting port 310 communicating with the collecting bin is also provided on the inner liner 300, and the setting position of the collecting port 310 corresponds to the sampling port 110. In addition, a filtering structure for connecting the collecting bin and the cavity is also provided on the inner liner 300. In this way, under the negative pressure generated by the negative pressure generating device, the tissue obtained from the human body by the biopsy sampling device enters the cavity through the sampling port 110, enters the collecting bin through the collecting port 310 and is collected, and the tissue fluid or blood that enters the collecting bin with the tissue enters the cavity through the filtering structure under the action of the negative pressure, and is discharged through the negative pressure port 120.

[0045] When it is necessary to remove the tissue, the sealing cover 200 is opened and the inner liner 300 can be taken out from the box body 100 to obtain the tissue. After the inner liner 300 is taken out, the sealing cover 200 is quickly covered on the box body 100, so that the cavity can maintain negative pressure after the inner liner 300 is taken out, which can prevent foreign matter from entering the cavity during the process of opening the collector to obtain biopsy tissue, which is beneficial to prevent the inside of the collector from being contaminated; and maintaining negative pressure in the cavity is also beneficial to prevent the residual biopsy tissue in the collector from overflowing, which is beneficial to keep the outside of the collector clean.

[0046] In this solution, the sealing cover 200 is openably and closably arranged on the box body 100, and the inner liner 300 is detachably arranged in the box body 100. The opening on the cavity is sealed by the sealing cover 200, so that the cavity can maintain negative pressure after the inner liner 300 is taken out, which is beneficial to avoid foreign matter from entering the cavity during the process of opening the collector to obtain biopsy tissue, prevent the inside of the collector from being contaminated, and prevent the residual biopsy tissue in the collector from overflowing.

[0047] It should be noted that Figure 2 and Figure 4In the corresponding embodiment, the above-mentioned “the position of the collecting port 310 corresponds to the injection port 110” means that the collecting port 310 is arranged on the side of the inner liner 300 facing the injection port 110, and is directly open to the injection port 110; in the actual implementation process (not shown in the figure), the above-mentioned “the position of the collecting port 310 corresponds to the injection port 110” can also mean that the collecting port 310 is open to the side where the sealing cover 200 is located, and at least part of the edge of the collecting port 310 is lower than the position of the injection port 110, so that the injection port 110 is exposed above the collecting port 310.

[0048] The above or below described biopsy tissue collector can be applied to 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 in the cavity or stuck at the collection port 310. Furthermore, the inner liner 300 can also be made of a transparent material, which is convenient for the user to observe in time whether the collection bin is full of biopsy tissue. When it is observed that the biopsy tissue is full, the sealing cover 200 needs to be opened, the inner liner 300 is taken out to empty the biopsy tissue, and then put into the cavity for the next collection. In addition, the inner liner 300 and the box body 100 are set to be detachably connected. When the biopsy tissue blocks the holes on the inner liner 300, the inner liner 300 can be easily taken out for cleaning or directly replaced to reduce costs.

[0049] It should be pointed out that if Figure 2 In the illustrated embodiment, the sample inlet 110 and the negative pressure port 120 on the box body 100 are arranged side by side and opposite to each other, so that the biopsy tissue can be sucked more smoothly by using the negative pressure.

[0050] Alternatively, if Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the sealing cover 200 includes a box cover 210 and a sealing member 220. When the box cover 210 covers the box body 100, the sealing member 220 is located between the box cover 210 and the box body 100 and seals the gap between the box cover 210 and the box body 100. The arrangement of the sealing member 220 can further improve the sealing performance of the box cover 210 to the cavity, realize the double sealing effect of the box cover 210 and the sealing member 220 on the cavity, and reduce negative pressure leakage. 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, the sealing member 220 is sleeved on the outer periphery of the extension portion, and the outer edge of the sealing member 220 abuts against the cavity wall of the cavity. After the box cover is closed, there is a gap between the box cover 210 and the box body 100, and the sealing member 220 is squeezed between the box cover 210 and the box body 100 to seal the gap, thereby ensuring the sealing during the biopsy tissue collection process. Furthermore, a gap is formed between the outer wall of the extension portion and the inner wall of the box body 100, Figure 2 , Figure 3In the example shown, the height of the seal 220 protruding from the outer wall of the extension portion is greater than the width of the gap. When the box cover 210 and the box body 100 are buckled together, the seal 220 can be bent in a direction close to or away from the inner liner 300, effectively preventing external gas from entering the sealed cavity. It can also ensure the generation of a good negative pressure effect, reducing problems such as poor collection effect and increased energy consumption caused by poor sealing.

[0051] Alternatively, if Figure 1 As shown, in one embodiment of the present invention, the box body 100 and the sealing cover 200 are an integrated structure. The integrated structure ensures that when the operator opens or closes the sealing cover 200 during surgery, there is no risk of the sealing cover 200 falling and being contaminated. The operator does not need to worry about the possibility of the sealing cover 200 falling, nor does he need to consider the placement of the sealing cover 200, which makes it more convenient to use. Figure 1 and Figure 2 As shown, in one embodiment of the utility model, in order to prevent the sealing cover 200 and the box body 100 from separating during the process of opening and closing the cover, one end of the sealing cover 200 is hinged to the box body 100, so that the sealing cover 200 and the box body 100 can be easily opened and closed by rotation.

[0052] Optionally, in an embodiment of the utility model, the sealing cover 200 is provided with a first connection part, and the box body 100 is correspondingly provided with a second connection part. A deformable thinning part is also integrally provided between the first connection part and the second connection part. The thinning part is made of an elastic material, and it can adaptively deform in the process of opening or closing the opening of the sealing cover 200. When the sealing cover 200 is closed, the thinning part is deformed by pressure; and when the sealing cover 200 is opened, the thinning part will restore its original shape, which is convenient for users to operate. Of course, in the actual implementation process, an elastic connection part can also be directly provided between the sealing cover 200 and the box body 100, so that one end of the elastic connection part is directly connected to the sealing cover 200, and the other end is directly connected to the box body 100.

[0053] Optionally, in an embodiment of the utility model, in order to improve the stability of the connection between the sealing cover 200 and the box body 100, a locking structure is also provided between the sealing cover 200 and the box body 100. In this embodiment, the specific structure of the locking structure is not specifically limited, for example, one of the sealing cover 200 and the box body 100 is provided with a Velcro hook surface, and the other is provided with a Velcro fur surface; in another embodiment of the utility model, the sealing cover 200 and the box body 100 can also adopt a locking method of a buckle and a slot, one of the box body 100 and the sealing cover 200 is provided with a buckle, and the other of the box body 100 and the sealing cover 200 is provided with a slot. Specifically, when it is necessary to open the sealing cover 200 to take out the liner 300, the button on the sealing cover 200 can be pressed to disengage the buckle from the slot, and the sealing cover 200 can be pulled in a direction away from the box body 100; when it is necessary to put the liner 300 into the cavity, the sealing cover 200 can be pressed so that the buckle is accurately buckled into the inside of the slot and can be used again. In this way, the box body 100 and the sealing cover 200 can be easily locked and fixed by the cooperation between the buckle and the slot.

[0054] Alternatively, if Figure 4 As shown, in one embodiment of the utility model, in order to facilitate the taking and placing of the inner liner 300, a clamping position 320 can be further provided on the inner liner 300, and the clamping position 320 is provided on the side of the inner liner 300 facing the sealing cover 200. When the inner liner 300 needs to be taken out or placed in the cavity, it is only necessary to clamp and fix the clamping position 320 of the inner liner 300 with tools such as tweezers or pliers, which is convenient for the user's operation.

[0055] Alternatively, if Figure 4 As shown, in one embodiment of the utility model, preferably, the clamping position 320 includes at least two clamping grooves, and the clamping grooves are not connected to the collection bin. Of course, in other embodiments, the clamping grooves may also be provided with three or four, etc. as required. Further preferably, the clamping groove is an arc groove, and the design of the arc groove is adapted to the contour of the user's finger, which can facilitate the user to clamp the liner 300 without using other auxiliary tools, thereby improving the collection work efficiency.

[0056] Optionally, in an embodiment of the present invention, in order to further fix the inner liner 300, an outer contour that matches the gap of the cavity can be provided on the inner liner 300, that is, the inner liner 300 is placed in the cavity without any restraint, and correspondingly, an inner contour that matches the outer contour is provided on the cavity wall of the cavity, so that the inner liner 300 can be effectively fixed in the cavity without adding any extra fixing structure. Of course, the present application does not exclude positioning the inner liner 300 in the cavity of the box body 100 by other detachable structures, such as by providing a positioning groove at the bottom or side wall of the cavity, etc., to securely fix the inner liner 300.

[0057] Alternatively, if Figure 4 As shown, in one embodiment of the utility model, in order to prevent the inner liner 300 from blocking the negative pressure port 120, the biopsy tissue collector also includes an anti-blocking member 400, which is arranged on the cavity wall of the cavity, and is arranged along the edge of the negative pressure port 120 and abuts against the outer wall of the inner liner 300, so that there is an anti-blocking gap between the outer wall of the inner liner 300 and the cavity wall of the cavity, which can effectively prevent the outer wall of the inner liner 300 from fitting tightly with the negative pressure port 120, causing the problem that a negative pressure state cannot be formed in the cavity, thereby affecting the collection of biopsy tissue. It should be explained that the anti-blocking member 400 can be a protrusion integrally formed on the cavity wall of the cavity, or it can be other components welded thereon later, as long as it can play the role of isolating the inner liner 300 and the negative pressure port 120.

[0058] Alternatively, if Figure 2 and Figure 3 As shown, in one embodiment of the utility model, the above-mentioned filtering structure can be a plurality of filtering holes 330 spaced apart on the inner liner 300, so that the collection chamber is connected to the negative pressure port 120 through the filtering holes 330, ensuring that the biopsy tissue can be smoothly sucked into the inner liner 300 by the negative pressure effect. 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 port 110, and some liquid tissues may enter the gap between the inner liner 300 and the box body 100. Under the action of negative pressure, the above-mentioned liquid tissue can enter the negative pressure port 120 through the filtering holes 330 and then be drawn out. It should be noted that the specific shape and number of the filtering holes 330 can be adjusted and designed as needed to meet the functional requirements, and are not limited here.

[0059] It should also be noted that the tissue collector can be directly connected to the tail or other parts of a biopsy tissue sampling device such as a biopsy needle, so that the sampling port 110 and the biopsy needle are integrated during the operation; it can also be connected to the sampling channel of the biopsy tissue sampling device through a pipeline, so that during the operation, the doctor only holds the biopsy tissue sampling device such as a biopsy needle without bearing the weight of the tissue collector. The following embodiments specifically illustrate how the tissue collector is connected to the pipeline of the biopsy tissue sampling device:

[0060] Alternatively, if Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment of the utility model, in order to facilitate the connection between the biopsy tissue collector and an external biopsy tissue sampling device, the biopsy tissue collector further includes a sampling tube 500, which is arranged on the outer wall of the box body 100 and communicates with the sampling port 110. The sampling tube 500 extends a certain length from the outer wall of the box body 100, which can be conveniently connected to the pipeline of the external biopsy tissue sampling device.

[0061] Alternatively, if Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment of the utility model, the biopsy tissue collector further includes a negative pressure tube 600, which is disposed on the outer wall of the box body 100 and communicates with the negative pressure port 120. The negative pressure tube 600 extends a certain length from the outer wall of the box body 100, and can be conveniently connected and fixed with the negative pressure generating device, avoiding the problem of separation between the two during the collection process, improving the stability of the connection between the two, and thus ensuring the negative pressure effect during sampling.

[0062] Furthermore, the sample injection tube 500 and the negative pressure tube 600 can be designed as an integrated structure with the box body 100, which can not only reduce the number of parts and assembly processes, but also reduce the parts that need to be sealed, thereby ensuring the negative pressure effect during sampling.

[0063] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
