Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and further to a sample storage tank and a biopsy rotary cutting device. Background Art

[0002] In recent years, the vacuum-assisted minimally invasive breast excision system has been widely used in the diagnosis and treatment of various breast diseases, such as early detection and diagnosis of breast cancer and minimally invasive resection of benign breast tumors, due to its characteristics of small incisions, small scars, and fast wound recovery during the treatment process.

[0003] In the related field, the conventional vacuum-assisted breast minimally invasive excision system has a biopsy excision device which mainly includes an excision unit and a sample collection device connected to the tail of the excision unit. During clinical diagnosis and treatment, after the excision inner blade of the excision unit cuts the sample tissue, the sample tissue is sucked out into the sample collection device through the negative pressure system for the doctor to observe during or after the operation to make a preliminary judgment on the patient's condition. Since the sample collection device needs to have a certain degree of sealing after being assembled to the tail of the excision unit, it cooperates with the negative pressure system to suck out the sample tissue in the inner blade of the excision unit. At present, most of the sample collection devices on the vacuum-assisted breast minimally invasive excision systems on the market are difficult to remove from the tail of the excision unit.

[0004] With respect to the above-mentioned related technologies, the inventors believe that, during a breast biopsy operation, when a large amount of sample tissue needs to be removed, the sample collecting device on the biopsy rotary cutting device is difficult to replace, which greatly prolongs the time of the biopsy operation, thereby bringing unknown risks to the operation process and affecting the success rate of the operation. There is room for improvement. Utility Model Content

[0005] The purpose of the present application is to provide a sample storage tank and a biopsy rotary cutting device, which are used to improve the convenience of replacing sample collection containers during breast biopsy surgery, so as to shorten the biopsy surgery time, thereby reducing the risk of biopsy surgery and improving the success rate.

[0006] The technical solutions provided by this application are as follows:

[0007] The present application provides a sample storage tank, which is installed on a biopsy peeling device and is used to communicate with the peeling inner blade of the biopsy peeling device to cooperate with a negative pressure system to collect sample tissue cut by the peeling inner blade, and is characterized in that it includes:

[0008] A tank body, the tank body comprising an end plate and a sample collecting cavity, the end plate being in a round pancake-shaped structure, the sample collecting cavities being provided with a plurality of them, the plurality of sample collecting cavities being all located on one side of the thickness direction of the end plate, and being arranged in a circular array around the axis of the end plate; a first interface and a second interface are provided on the end plate corresponding to any of the sample collecting cavities, the first interface being used to connect to an end of the rotary cutting inner blade away from the blade head, and the second interface being used to connect to the air pipe of the negative pressure system;

[0009] A driving member, the driving member is mounted on the tank body and is used to drive the tank body to rotate around the axis of the end plate, so that the first interfaces and the second interfaces of the plurality of sample collecting cavities are connected to the rotary cutting inner blade and the air pipe of the negative pressure system in sequence;

[0010] A positioning piece is installed on the end plate and corresponds to each of the sample collecting cavities one by one. The positioning piece is used to assist each of the sample collecting cavities in positioning the rotary cutting inner blade and the negative pressure system to ensure that the first interface of each of the sample collecting cavities is connected to the rotary cutting inner blade, and the second interface is connected to the air pipe of the negative pressure system.

[0011] Through the sample storage tank provided by the present application, in clinical applications, when performing a breast biopsy operation, the driving member is first used to drive the tank body to rotate around the axis of the end plate. After the identification end on the biopsy rotary cutting device identifies one of the positioning members, the tank body stops rotating, and the first interface of the corresponding sample collection cavity is connected to the rotary cutting inner knife, and the second interface is connected to the trachea of ​​the negative pressure system, so as to ensure the normal progress of the surgical operation; specifically, after the rotary cutting inner knife of the biopsy rotary cutting device cuts the sample tissue, the negative pressure system makes the corresponding sample collection cavity present a negative pressure environment, and the cut sample tissue is collected into the corresponding sample collection cavity along the rotary cutting inner knife;

[0012] When a large number of sample tissues are required, after the first sample collecting cavity is full, the driving part is started again, and the driving part is used to drive the tank body to rotate around the axis of the end plate until the identification end on the biopsy peeling device identifies the next positioning part, so that the first interface and the second interface of the next sample collecting cavity are connected to the peeling inner knife and the trachea of ​​the negative pressure system respectively; thereafter, the sample tissues cut by the peeling inner knife are collected in the corresponding second sample collecting cavity; similarly, if sampling is still required after the second sample collecting cavity is full, the driving part is continued to be used to drive the tank body to rotate, and this cycle is repeated until the breast biopsy operation is completed.

[0013] In this way, multiple sample collecting cavities are arranged in a circular array on the tank body, and the first interfaces and second interfaces of the multiple sample collecting cavities are connected to the inner rotary cutting knife and the trachea of ​​the negative pressure system in sequence by rotation, so as to replace the sample collecting device that cooperates with the rotary cutting device. The entire replacement process does not require the tank body to be removed from the biopsy rotary cutting device. The operation is convenient, time-saving and labor-saving, which helps to shorten the breast biopsy operation time, thereby greatly reducing the probability of unknown risks during the operation and improving the success rate of the operation.

[0014] In some embodiments, the positioning member includes a magnet, and a plurality of the magnets are arranged in a circular array around the axis of the end plate. When in use, the plurality of magnets are sequentially identified by the identification end on the biopsy excision device.

[0015] In a sample storage tank provided by the present application, the positioning piece is set as a magnet, and the magnet is identified by utilizing the identification end on the biopsy peeling device to realize magnetic positioning of each sample collection cavity with the peeling inner knife and the negative pressure system. The structure is simple, the production is convenient, and it helps to reduce the production cost of the enterprise.

[0016] In some embodiments, the driving member includes a connecting rod and a driving gear, the connecting rod is coaxially mounted on the end plate, and the driving gear is coaxially fixedly sleeved on an end of the connecting rod away from the end plate.

[0017] A sample storage tank provided by the present application can be assembled on a biopsy peeling device and, in clinical applications, when a sample collecting device needs to be replaced, the electrically controlled drive gear rotates, and drives the connecting rod and the tank body to rotate synchronously relative to the biopsy peeling device, thereby replacing the sample collecting chamber connected to the peeling inner knife and the negative pressure system; the driving structure is simple, and the sample collecting device replacement operation is convenient, which effectively saves the company's production costs and shortens the operation time.

[0018] In some embodiments, one end of any of the sample collecting chambers away from the end plate is open;

[0019] The sample storage tank further comprises a collection basket, which corresponds to the sample collecting cavity one by one and is respectively loaded into the corresponding sample collecting cavity from the open end of the corresponding sample collecting cavity; a docking hole is provided at one end of the collection basket close to the end plate, and the docking hole is communicated with the corresponding first interface;

[0020] A sealing ring is provided between the inner wall of any sample collecting chamber and the corresponding collection basket, and the sealing ring is located at the end of the collection basket away from the docking hole. The sealing ring is fixedly sleeved on the outer wall of the collection basket and tightly pressed against the inner wall of the sample collecting chamber to form a sealed environment in the corresponding sample collecting chamber.

[0021] Through the sample storage tank provided by the present application, in clinical applications, after the rotary cutting inner knife of the biopsy rotary cutting device cuts the sample tissue, the negative pressure system creates a negative pressure environment in the corresponding sample collection cavity, and allows the cut sample tissue to pass through the first interface and the docking hole in sequence along the axial direction of the rotary cutting inner knife and be collected in the corresponding collection basket; when a large number of sample tissues are required, after the collection baskets in each sample collection cavity are full, it is only necessary to replace the collection basket to achieve continued sample collection in the sample storage tank, without removing the tank body from the biopsy rotary cutting device. The operation is simple, which helps to further improve the operating efficiency when replacing the sample collection cavity, thereby further shortening the breast biopsy operation time and further improving the success rate of the operation.

[0022] At the same time, the end of the sample collecting cavity away from the end plate is set to an open shape, the collecting basket is loaded into the sample collecting cavity from the open end, and a sealing ring is used to form a sealed environment in the corresponding sample collecting cavity, so that the sample storage tank has a simple structure and is easy to use, which helps to further improve the operating efficiency when replacing the sample collecting cavity, thereby further shortening the breast biopsy operation time and further improving the success rate of the operation.

[0023] In some embodiments, a rear cover is installed at one end of any of the collecting baskets that is away from the docking hole, and after the collecting basket is loaded into the corresponding sample collecting cavity, the rear cover protrudes out of the sample collecting cavity.

[0024] With the sample storage tank provided by the present application, in clinical applications, the collection basket can be removed from the corresponding sample collection cavity by simply holding and pulling the back cover, thereby effectively improving the convenience of replacing the collection basket.

[0025] In some embodiments, a guide slide is formed on the inner wall of any sample collecting cavity along the axis of the end plate, a guide groove is formed on the collecting basket corresponding to the guide slide, the guide slide is embedded in the guide groove, and slides with the inner wall of the guide groove along the axis of the end plate.

[0026] A sample storage tank provided by the present application realizes accurate installation of the collection basket in the sample collection cavity by means of the sliding cooperation between the guide slide bar and the inner wall of the guide groove. It has a simple structure, is easy to manufacture, and effectively saves the production cost of the enterprise.

[0027] In some embodiments, the guide groove is opened at any two opposite ends of the opening end of the collection basket.

[0028] With a sample storage tank provided by the present application, a guide groove is opened at the open end of the collection basket, which reduces the contact area between the collection basket and the guide slide bar, helps to ensure smooth sliding of the guide slide bar relative to the collection basket, and further improves the convenience when replacing the collection basket.

[0029] In some embodiments, a blood leakage hole is opened on the bottom wall of the collection basket, and the bottom wall of the collection basket is inclined to form a blood-water cavity between the bottom wall and the inner wall of the sample collection cavity, and the blood-water cavity is connected to the second interface.

[0030] Through the sample storage tank provided by the present application, the bottom wall of the collection basket is set to an inclined shape. In clinical applications, after the sample tissue enters the collection basket, the blood and water thereon enter the blood and water cavity through the blood leakage hole, and then flow into the negative pressure system through the second interface to achieve separation from the sample tissue; the blood and water separation structure is simple, which effectively reduces the production difficulty of the enterprise and saves production costs.

[0031] In some embodiments, a fixed cover plate is further included, which is slidably sleeved on the connecting rod and coaxially arranged with the end plate; a sealing gasket is fixedly clamped between the fixed cover plate and the connecting rod.

[0032] In a sample storage tank provided by the present application, a sealing gasket is used to seal one end of the tank body close to the end plate to ensure the airtightness of the negative pressure system, thereby ensuring the normal progress of the corresponding breast biopsy operation.

[0033] On the other hand, a biopsy peeling device is also provided, comprising any of the above-mentioned sample storage tanks, and also comprising a peeling inner knife and a negative pressure system, wherein the sample storage tank comprises a plurality of sample collecting cavities, and the first interface and the second interface of the plurality of sample collecting cavities are connected in sequence to the end of the peeling inner knife away from the blade head and the trachea of ​​the negative pressure system.

[0034] Compared with the prior art, the sample storage tank and biopsy peeling device provided by the present application have at least one of the following beneficial effects:

[0035] 1. By arranging a plurality of sample collecting cavities in a circumferential array on the tank body, and using a rotating method to sequentially connect the first interface and the second interface of the plurality of sample collecting cavities to the inner rotary cutting knife and the trachea of ​​the negative pressure system, the sample collecting device matched with the rotary cutting device can be replaced. During the entire replacement process, the tank body does not need to be removed from the biopsy rotary cutting device, which is convenient to operate, saves time and effort, and helps to shorten the breast biopsy operation time, thereby greatly reducing the probability of unknown risks during the operation and improving the success rate of the operation;

[0036] 2. By installing a collection basket in the sample collection cavity, when a large number of sample tissues are required, after the collection baskets in each sample collection cavity are full, only the collection basket needs to be replaced to realize the continuous collection of samples in the sample storage tank, so that the number of samples that can be collected by the biopsy peeling device is not limited, which helps to expand the application scope of the biopsy peeling device and enhance its practicality;

[0037] 3.

[0047] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0048] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0049] In one embodiment, referring to the accompanying drawings of the specification Figure 1 to Figure 2A sample storage tank is suitable for a biopsy peeling device and is connected to the tail of the peeling member, specifically to the end of the peeling inner blade 100 away from the blade head, and is connected to the negative pressure system 200, so that it is in a negative pressure state under the action of the negative pressure system 200, thereby collecting the sample tissue cut by the peeling inner blade 100.

[0050] It includes a tank body 1 consisting of an end plate 11 and a sample collecting chamber 12. Specifically, the end plate 11 is a pancake-shaped structure, and the sample collecting chamber 12 is arranged on one side of the end plate 11 in the thickness direction, and is provided with a plurality of sample collecting chambers 12, which are arranged in a circular array around the axis of the end plate 11; and, a first interface 111 and a second interface 112 are opened on the end plate 11 corresponding to any sample collecting chamber 12, wherein the first interface 111 is used to connect to the rotary cutting inner knife 100, and the second interface 112 is used to connect to the trachea of ​​the negative pressure system 200; during clinical application, the tank body 1 rotates around the axis of the end plate 11 relative to the rotary cutting member, so that the plurality of sample collecting chambers 12 are connected to the rotary cutting inner knife 100 and the negative pressure system 200 in sequence through their own first interface 111 and second interface 112. In this embodiment of the present application, the sample storage tank also includes a driving member 2 that assists the tank body 1 in rotating around the axis of the end plate 11, and the driving member 2 is installed on the tank body 1; at the same time, a positioning member 3 is also installed on the tank body 1, and the positioning member 3 is arranged corresponding to the sample collecting chamber 12, and is used to adapt to the identification end on the biopsy peeling device, so as to ensure that each sample collecting chamber 12 is connected to the peeling inner knife 100 and the negative pressure system 200 in turn through the first interface 111 and the second interface 112 during the process of the driving member 2 driving the tank body 1 to rotate.

[0051] In clinical applications, when performing a breast biopsy operation, the driving member 2 is first used to drive the tank body 1 to rotate around the axis of the end plate 11, so that the identification end on the biopsy rotary cutting device first identifies a positioning member 3; at the same time, the tank body 1 stops rotating, and the first interface 111 of the sample collecting cavity 12 corresponding to the positioning member 3 is connected to the rotary cutting inner knife 100, and the second interface 112 is connected to the trachea of ​​the negative pressure system 200, so as to ensure the normal progress of the surgical operation; after the rotary cutting inner knife 100 cuts the breast sample tissue, the corresponding sample collecting cavity 12 cooperates with the negative pressure system 200 to collect the corresponding sample tissue. When the required number of sample tissues is large and the first sample collecting chamber 12 cannot fully accommodate them, it is only necessary to use the driving member 2 to drive the tank body 1 to rotate around the axis of the end plate 11 again until the identification end on the biopsy rotary cutting device identifies the next positioning member 3, so that the first interface 111 and the second interface 112 of the next sample collecting chamber 12 are connected to the rotary cutting inner knife 100 and the trachea of ​​the negative pressure system 200 respectively; thereafter, the sample tissues cut by the rotary cutting inner knife 100 are collected in the second sample collecting chamber 12; similarly, if sampling still needs to be continued after the second sample collecting chamber 12 is full, continue to use the driving member 2 to drive the tank body 1 to rotate, and repeat this cycle until the breast biopsy operation is completed.

[0052] In this way, a plurality of sample collecting chambers 12 are arranged in a circular array on the tank body 1, and the tank body 1 is rotated in cooperation with the driving member 2, so that the plurality of sample collecting chambers 12 are connected to the rotary cutting inner knife 100 and the negative pressure system 200 through the first interface 111 and the second interface 112 in sequence, thereby realizing the switching of the sample collecting container; since the sample collecting container does not need to be removed from the rotary cutting device during the replacement process, the sample collecting container replacement operation is simple, fast, time-saving and labor-saving, thereby effectively shortening the duration of the breast biopsy operation, greatly reducing the probability of unknown risks occurring during the operation, and improving the success rate of the operation.

[0053] In one embodiment, based on the above-mentioned embodiments, specifically, the first interface 111 and the second interface 112 of any sample collecting chamber 12 are arranged in sequence along the radial direction of the corresponding position of the end plate 11. In order to improve the airtightness of each sample collecting chamber 12, this embodiment of the present application also includes a sealing gasket 4 that is detachably installed on the side of the end plate 11 away from the sample collecting chamber 12, and the sealing gasket 4 is coaxially arranged with the end plate 11; of course, in order to fix the sealing gasket 4, a round pancake-shaped fixed cover plate 5 is also included, and the fixed cover plate 5 is coaxially installed on the side of the sealing gasket 4 away from the end plate 11, and the sealing gasket 4 is pressed against the end plate 11.

[0054] In this embodiment of the present application, refer to Figure 2 and Figure 3 The driving member 2 includes a connecting rod 21 mounted on the end plate 11, the connecting rod 21 is located at the central axis of the end plate 11, and is coaxially fixed with the end plate 11; the connecting rod 21 extends along its own axial direction toward the end away from the sample collecting chamber 12, and sequentially penetrates the sealing gasket 4 and the fixed cover plate 5; at the same time, the driving member 2 also includes a driving gear 22, the driving gear 22 is coaxially fixedly sleeved on the end of the connecting rod 21 away from the end plate 11, and the driving gear 22 is specifically located at the end of the fixed cover plate 5 away from the sample collecting chamber 12. Of course, the driving gear 22 can be fixedly sleeved on the connecting rod 21 by key connection, bonding, welding, etc., and the embodiment of the present application does not specifically limit the connection method between the driving gear 22 and the connecting rod 21.

[0055] After the sample storage tank is assembled on the biopsy peeling device, in clinical applications, when it is necessary to switch the sample collection chamber 12 connected to the peeling inner blade 100, the driving gear 22 is rotated by electrical control, so that the driving gear 22 drives the connecting rod 21 and the tank body 1 to rotate synchronously relative to the biopsy peeling device. The driving structure is simple, easy to manufacture and use, effectively saving the production cost of the enterprise, and improving the stability and convenience of the surgical process.

[0056] In this embodiment of the present application, the positioning member 3 includes a magnet, and a plurality of magnets are provided corresponding to the sample collection chamber 12, and the plurality of magnets are fixedly embedded in the end plate 11 and arranged in a circular array around the axis of the end plate 11. When the driving gear 22 drives the tank body 1 to rotate relative to the biopsy peeling device, the identification end on the biopsy peeling device, such as the control chip, senses any magnet and transmits the corresponding signal to the controller of the biopsy peeling device, thereby controlling the driving gear 22 and the tank body 1 to stop rotating, and realizing the magnetic positioning of the corresponding sample collection chamber 12 with the peeling inner blade 100 and the negative pressure system 200, so that the first interface 111 and the second interface 112 of one of the sample collection chambers 12 are connected to the peeling inner blade 100 and the negative pressure system 200.

[0057] Of course, in order to improve the accuracy of positioning the rotary cutting inner blade 100 and the negative pressure system 200 corresponding to the first interface 111 and the second interface 112, refer to Figure 2 and Figure 4 In the embodiment of the present application, a positioning groove 113 can also be opened on the edge of the end plate 11, and a plurality of positioning grooves 113 are opened, and they correspond to the magnets one by one; at the same time, the corresponding positioning grooves 113 on the biopsy peeling device are formed with positioning convex points; after the first interface 111 and the second interface 112 of one of the sample collecting cavities 12 are connected to the peeling inner knife 100 and the negative pressure system 200, the identification end on the biopsy peeling device, such as the control chip, senses the corresponding magnet, and at the same time, the positioning convex point is embedded in the corresponding positioning groove 113, so as to realize the structural positioning of the sample storage tank and the biopsy peeling device; when the driving gear 22 drives the tank body 1 to rotate relative to the biopsy peeling device again, the positioning convex point is disengaged from the corresponding positioning groove 113 under the action of force until the identification end on the biopsy peeling device recognizes the next magnet; at the same time, the positioning convex point is embedded in another positioning groove 113.

[0058] Reference Figure 3 and Figure 4Furthermore, in order to enable the sample storage tank to meet the collection volume of a larger sample tissue and reduce the limit on the number of samples to be taken, the sample storage tank further includes a collection basket 6, and the collection basket 6 corresponds to the sample collection cavity 12 one by one and is installed in the corresponding sample collection cavity 12; a docking hole 61 is provided in each collection basket 6 corresponding to the first interface 111, so that the collection basket 6 is connected to the rotary cutting inner knife 100. Specifically, in order to facilitate the loading and unloading of the collection basket 6, the end of each sample collection cavity 12 away from the end plate 11 is set to be open, and each collection basket 6 is loaded into the corresponding sample collection cavity 12 from the open end of the sample collection cavity 12. In addition, a guide slide 121 is formed in the axial direction of the end plate 11 in any sample collection cavity 12, and a guide groove 62 is provided on the side wall of any collection basket 6 corresponding to the guide slide 121; when in use, any collection basket 6 is loaded into the corresponding sample collection cavity 12 from the open end of the sample collection cavity 12, and the guide slide 121 in any sample collection cavity 12 is embedded in the corresponding guide groove 62, and slides relative to the inner wall of the guide groove 62 along the axial direction of the end plate 11, so that the docking hole 61 accurately docks with the first interface 111. In addition, in order to ensure the smoothness when loading and unloading the collection basket 6, in this embodiment of the present application, the guide groove 62 is provided at any two opposite ends of the open end of the collection basket 6.

[0059] At the same time, in order to ensure the airtightness of the negative pressure system 200 and to ensure that the sample collecting chamber 12 is in a sealed state, a sealing ring 63 is provided between the inner wall of any sample collecting chamber 12 and the outer wall of the corresponding collecting basket 6, and any sealing ring 63 is provided at the end of the inner wall of the sample collecting chamber 12 away from the end plate 11; when installing the collecting basket 6, firstly, the sealing ring 63 is sleeved on the end of the collecting basket 6 away from the docking hole 61, and then the guide slide 121 is embedded in the corresponding guide groove 62, and the collecting basket 6 is inserted into the corresponding sample collecting chamber 12 along the axial direction of the end plate 11 until the sealing ring 63 is tightly pressed between the inner wall of the sample collecting chamber 12 and the outer wall of the corresponding collecting basket 6. Furthermore, in order to prevent the sealing ring 63 from slipping relative to the collecting basket 6, causing the sealing ring 63 to move to the bleeding hole 65 and affect the sealing of the sample collecting chamber 12, in this embodiment of the present application, a card groove 122 is provided at one end of the inner wall of any sample collecting chamber 12 away from the end plate 11, and after the sealing ring 63 is embedded between the sample collecting chamber 12 and the corresponding collecting basket 6, it abuts against the end face of the card groove 122 facing the open end of the sample collecting chamber 12, thereby limiting the installation position of the sealing ring 63 on the collecting basket 6.

[0060] Reference Figures 1 to 3In order to improve the convenience of loading and unloading the collection basket 6, a rear cover 64 is installed at one end of any collection basket 6 away from the docking hole 61; specifically, a snap-on structure is provided between the end of the collection basket 6 away from the docking hole 61 and the rear cover 64, and any rear cover 64 is detachably connected to the collection basket 6 through the snap-on structure. Moreover, after the collection basket 6 is loaded into the corresponding sample collecting cavity 12, one end of any rear cover 64 away from the snap-on structure protrudes out of the corresponding sample collecting cavity 12. In addition, a holding position 641 is provided on the outer wall of any rear cover 64 to further improve the convenience of loading and unloading the collection basket 6. In clinical applications, when replacing the collection basket 6, it is only necessary to hold the holding position 641 and pull or push the rear cover 64 axially along the end plate 11 to remove the collection basket 6 from the corresponding sample collecting cavity 12 or reload it into the sample collecting cavity 12.

After the corresponding collection basket 6 is filled and taken out from the corresponding sample collection chamber 12, the sample tissue is poured out from the basket opening of the collection basket 6 to ensure the efficiency of taking out the sample tissue; the bottom wall of any collection basket 6 is arranged corresponding to the basket opening, and a plurality of blood leakage holes 65 are evenly distributed; at the same time, the bottom wall of any collection basket 6 is arranged inclined, and a blood-water cavity 7 is formed between the bottom wall of the corresponding sample collection chamber 12, and the blood-water cavity 7 is connected to the second interface 112.

[0062] In clinical applications, after the sample tissue enters the collection basket 6, the blood on it enters the blood cavity 7 through the blood leakage hole 65, and then flows into the cavity of the negative pressure system 200 through the second interface 112, thereby achieving the separation of blood and sample tissue, which is convenient for doctors to observe the morphology of the sample tissue and preliminarily judge the patient's condition.

[0063] The implementation principle of the embodiment of the present application is as follows: in clinical applications, when performing a breast biopsy operation, the driving gear 22 is first rotated by electrically controlling the driving gear 22 so that the driving gear 22 drives the tank body 1 to rotate synchronously relative to the biopsy peeling device; after the identification end on the biopsy peeling device identifies any magnet, the corresponding signal is transmitted to the controller of the biopsy peeling device, thereby controlling the driving gear 22 and the tank body 1 to stop rotating, thereby realizing the magnetic positioning of the corresponding sample collecting chamber 12 with the peeling inner knife 100 and the negative pressure system 200, so that the first interface 111 and the second interface 112 of one of the sample collecting chambers 12 are connected to the peeling inner knife 100 and the negative pressure system 200, thereby ensuring the normal progress of the surgical operation; after the peeling inner knife 100 cuts the breast sample tissue, the collection basket 6 in the corresponding sample collecting chamber 12 cooperates with the negative pressure system 200 to collect the corresponding sample tissue.

[0064] When the required number of sample tissues is large and the first collection basket 6 cannot fully accommodate them, it is only necessary to electrically control the driving gear 22 to rotate again until the identification end on the biopsy peeling device identifies the next magnet, so that the first interface 111 and the second interface 112 of the next sample collection chamber 12 are connected to the peeling inner knife 100 and the trachea of ​​the negative pressure system 200 respectively; thereafter, the sample tissues cut by the peeling inner knife 100 are collected in the second collection basket 6; similarly, if sampling still needs to be continued after the second collection basket 6 is full, the tank body 1 is continued to be driven to rotate, and this cycle is repeated until the breast biopsy operation is completed.

[0065] When the collection baskets 6 in the sample collection cavity 12 are filled with sample tissue but sampling still needs to be continued, the doctor holds the holding position 641 and pulls the rear cover 64 axially along the end plate 11 to remove the corresponding collection baskets 6 from the corresponding sample collection cavity 12 one by one, and reloads new empty collection baskets 6 to continue the biopsy operation.

[0066] By replacing the sample collection container in this way, since there is no need to remove the sample collection container from the inspection and peeling device during the replacement process, the sample collection container replacement operation is simple and quick, saving time and effort, effectively shortening the duration of the breast biopsy operation, greatly reducing the probability of unknown risks during the operation, and improving the success rate of the operation.

[0067] In one embodiment, a biopsy peeling device includes the sample storage tank described in the above embodiment, and also includes a peeling inner blade 100 and a negative pressure system 200. The multiple sample collecting cavities 12 of the sample storage tank are connected to the peeling inner blade 100 and the negative pressure system 200 in sequence around the axis of the end plate 11, so as to replace the sample collecting container in operation.

[0068] It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
