Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a rotary cutting device. Background Technology

[0002] A rotary cutting device is a surgical instrument used to obtain tissue specimens from inside the human body and to image the specimens using X-rays to obtain high-resolution radiographic images. Specifically, the rotary cutting device includes:

[0003] A rotary cutter is used to cut tissue by rotating itself to obtain a specimen; the rotary cutter has channels on it.

[0004] A visualization container, one end of which is connected to a channel, is used to hold the specimen to be photographed as it enters through the channel;

[0005] The imaging unit, located on one side of the visualization container, is used to emit X-rays to take X-ray images of the specimen to be photographed.

[0006] The sample injection unit is connected to the other end of the visualization container to create negative pressure, which drives the specimen to be photographed to enter the visualization container through the channel.

[0007] However, in actual use, if the adsorption force of the sample introduction unit is too large, it will cause the sample to move too much, resulting in the sample moving beyond the visualization container. In this case, the position of the sample needs to be adjusted, which reduces the imaging efficiency of the imaging unit. Utility Model Content

[0008] In view of this, the present invention provides a rotary cutting device to solve the problem that the excessive adsorption force of the existing driving structure leads to low imaging efficiency of the imaging unit.

[0009] This utility model provides a rotary cutting device, comprising:

[0010] A visualization container includes a receiving cavity, the two ends of which are a sample inlet and a sample outlet, the sample inlet being used to communicate with the channel of a rotary cutter;

[0011] The sample introduction unit, connected to the sample outlet, is used to generate an adsorption airflow to drive the specimen to be photographed in the rotary cutter to the receiving cavity;

[0012] A limiting unit is provided on one side of the sample outlet end, used to adjust the opening degree of the receiving cavity corresponding to the sample outlet end;

[0013] A limiting unit, located on one side of the sample outlet, is used to adjust the opening of the corresponding receiving cavity at the sample outlet.

[0014] Beneficial effects: By setting a limiting unit, the position of the specimen to be photographed in the visualization container can be restricted, avoiding excessive movement of the specimen by the injection unit, which would cause the specimen to move beyond the position of the injection unit and affect the imaging of the specimen, thus reducing the working efficiency of the rotary cutting device. This improves the accuracy of the specimen's position in the receiving cavity, thereby achieving the technical effect of improving the working efficiency of the rotary cutting device.

[0015] In one alternative implementation, the size of the receiving cavity is matched to the size of the specimen to be photographed along a direction perpendicular to the movement of the specimen.

[0016] Alternatively, the size of the receiving cavity is larger than the size of the specimen to be photographed, along a direction perpendicular to the movement of the specimen.

[0017] Beneficial effects: By limiting the direction of movement perpendicular to the specimen and matching the size of the receiving cavity to the size of the specimen, the receiving cavity can effectively limit the direction of movement of the specimen, thereby improving the stability of the specimen's movement. Simultaneously, by limiting the direction of movement perpendicular to the specimen, the size of the receiving cavity can be larger than the size of the specimen. This prevents the ends of the visualization container along the direction perpendicular to the specimen's movement from falling within the imaging range of the imaging unit, thus avoiding any impact on the accuracy of the photographic image and improving the precision of the photographic image.

[0018] In one optional embodiment, the size of the receiving cavity matches the size of the specimen to be photographed along a direction perpendicular to the movement of the specimen, and the limiting unit includes:

[0019] A first flexible structure is connected between the sample outlet and the sample injection unit;

[0020] A first driving structure is disposed on at least one side of the first flexible structure for compressing the first flexible structure to adjust the opening of the receiving cavity corresponding to the sample outlet.

[0021] Beneficial effect: The first driving structure can drive the first flexible structure to deform, forming an obstruction to the specimen to be photographed, so that the specimen to be photographed cannot move beyond the position of the visualization container, thereby achieving the technical effect of limiting the position of the specimen to be photographed.

[0022] In one optional implementation, the first driving structure includes:

[0023] At least two movable parts are respectively disposed on both sides of the first flexible structure, for clamping the first flexible structure or moving away from the first flexible structure;

[0024] A first driving unit is connected to the moving unit and is used to drive the moving unit to move.

[0025] Beneficial effects: The first driving part drives at least two moving parts to clamp the first flexible structure, thereby blocking the movement path of the specimen to be photographed. The first driving part can also drive at least two moving parts away from the first flexible structure. At this time, the first flexible tube returns to its original shape, and the specimen to be photographed can enter the collection unit through the first flexible tube.

[0026] In one optional embodiment, along a direction perpendicular to the movement of the specimen to be photographed, the size of the receiving cavity is larger than the size of the specimen to be photographed, and the limiting unit includes:

[0027] A first limiting structure is provided on at least one side of the visualization container, and one end of the first limiting structure passes through the visualization container to adjust the size of the receiving cavity along the direction of movement perpendicular to the specimen to be photographed under the action of external force, so as to limit the position of the specimen to be photographed.

[0028] The second driving structure is connected to the other end of the first limiting structure and is used to drive the first limiting structure to move in order to adjust the opening of the receiving cavity corresponding to the sample outlet.

[0029] Beneficial effects: The first limiting structure is driven by the second driving structure to move along the direction perpendicular to the movement of the specimen to be photographed. The degree of obstruction of the receiving cavity by the first limiting structure is used to adjust the opening of the receiving cavity corresponding to the sample outlet, so as to limit the position of the specimen to be photographed as needed.

[0030] In one optional embodiment, the first limiting structure is provided with a flow hole, which is connected to both the sample inlet and the sample outlet.

[0031] Beneficial effect: When the first limiting structure blocks the specimen to be photographed, the sample injection unit can drive the specimen to move to the position of the first limiting structure so as to perform photographic imaging on the specimen.

[0032] In one optional implementation, the second driving structure includes:

[0033] Support structure;

[0034] The elastic part has one end connected to the support structure and the other end connected to the other end of the first limiting structure;

[0035] The second driving unit is connected to the elastic part and is used to adjust the elastic force of the elastic part.

[0036] Beneficial effects: The second driving part drives the elastic part to be in a compressed state, that is, the elastic part can drive the first limiting structure to move in the direction of increasing the opening of the receiving cavity. When the second driving part no longer drives the elastic part to be in a compressed state, under the action of elastic force, the elastic part drives the first limiting structure to be in a state of blocking the receiving cavity, so that the first limiting structure can limit the position of the photographic specimen.

[0037] In one optional embodiment, the second driving unit includes:

[0038] A magnetic component is located at the other end of the first limiting structure;

[0039] An electromagnetic component is disposed on the side of the support structure near the elastic part, used to generate magnetism to attract the magnetic component when energized, and to separate the magnetic component when the electromagnetic property disappears.

[0040] Beneficial effects: When the electromagnetic component is magnetic, it can attract the magnetic component, causing the first limiting part to move along the opening direction of the receiving cavity. When the electromagnetic component is not magnetic, the elastic force of the elastic part drives the first limiting part to move along the direction of reducing the opening of the receiving cavity, so as to adjust the opening of the receiving cavity.

[0041] In one optional implementation, the limiting unit includes:

[0042] A second limiting structure is provided on at least one side of the visualization container, with one end of the second limiting structure passing through the visualization container. It is used to adjust the size of the visualization container along the direction of movement perpendicular to the direction of movement of the specimen under the action of external force, so as to limit the direction of movement of the specimen.

[0043] Beneficial effects: By driving the second limiting structure to move along the direction of movement perpendicular to the specimen to be photographed by external force, even if the dimensions of the receiving cavity on both sides of the direction of movement parallel to the specimen to be photographed are much larger than the dimensions of the specimen to be photographed, the second limiting structure will still limit the direction of movement of the specimen to be photographed, so that the specimen to be photographed can move from the sample inlet to the sample outlet, thereby achieving the technical effect of improving the accuracy of the direction of movement of the specimen to be photographed.

[0044] In one optional embodiment, the visualization container has a second receiving groove on at least one side, and at least one baffle structure is provided inside the visualization container. The second limiting structure passes through the second receiving groove and is connected to the baffle structure, for adjusting the distance between the baffle structure and the inner wall of the visualization container, or the distance between the baffle structures arranged opposite each other, along the direction of movement perpendicular to the specimen to be photographed, under the action of external force.

[0045] Beneficial effect: The stop arm structure can increase the contact area between the second limiting structure and the specimen to be photographed, thereby improving the stability of the position limitation of the specimen to be photographed. Attached Figure Description

[0061] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0062] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0063] In one embodiment of this utility model, a rotary cutting device is provided, comprising:

[0064] The visualization container 1 includes a receiving cavity, with a sample inlet 101 and a sample outlet 102 at its two ends. The sample inlet 101 is used to communicate with the channel of the rotary cutter 7.

[0065] The sample injection unit 2 is connected to the sample outlet 102 and is used to generate an adsorption airflow to drive the specimen 4 to be photographed in the rotary cutter 7 to move into the receiving cavity;

[0066] The limiting unit 3 is located on one side of the sample outlet 102 and is used to adjust the opening of the receiving cavity corresponding to the sample outlet 102.

[0067] In the rotary cutting device of this utility model, by setting the limiting unit 3, the position of the specimen 4 to be photographed in the visualization container 1 can be restricted, so as to prevent the sample injection unit 2 from driving the specimen 4 to move excessively, causing the specimen 4 to move beyond the position of the visualization container 1, which would affect the imaging of the specimen 4 and reduce the working efficiency of the rotary cutting device. This improves the accuracy of the position of the specimen 4 in the receiving cavity, thereby achieving the technical effect of improving the working efficiency of the rotary cutting device.

[0068] In addition, combined Figure 1 As shown, the rotary cutting device in this embodiment includes a photographic imaging unit 5, which is located on one side of the receiving cavity and is used to emit rays to each specimen 4 to be photographed in the receiving cavity, and to perform photographic imaging on the specimen 4 to be photographed by the rays.

[0069] In this embodiment, the imaging unit 5 emits X-rays to perform imaging on the specimen 4. Of course, in other embodiments, the type of rays emitted by the imaging unit 5 can be adjusted.

[0070] Furthermore, in this embodiment, the visualization container 1 is made of a transparent material to improve the accuracy of the photographic imaging unit 5 in imaging the specimen 4. For example, it can be made of polyethylene terephthalate (PET), a material that avoids attenuation of X-rays, ensuring the accuracy of the photographic imaging.

[0071] As an alternative implementation, the transparent material can also be polymethyl methacrylate (PMMA) or polycarbonate (PC).

[0072] In this embodiment, the visualization container 1 is made of a transparent material, meaning that the entire structure of the visualization container 1 is made of a transparent material. As an alternative implementation, the visualization container 1 may also be made of a transparent material only for the photographing portion, while other parts of the structure are made of a non-transparent material; this is not a limitation.

[0073] Of course, in other embodiments, the visualization method of the visualization container 1 can be adjusted according to the different designs of the rotary cutting device. For example, a sliding door can be provided on the surface of the visualization container 1. When it is necessary to photograph the specimen 4, the sliding door can be opened by external force to expose the specimen 4. Compared with other embodiments, in this embodiment, the visualization container 1 is made of transparent material, eliminating the need for manual opening of the sliding door, thereby improving the ease of setting up the visualization container 1.

[0074] In addition, combined Figure 1 As shown, in this embodiment, the imaging unit 5 includes:

[0075] X-ray emitter 501, located on one side of visualization container 1, is used to emit X-rays to take X-ray images of the specimen 4 to be photographed;

[0076] Detector 502 is located on the side of the visualization container 1 away from the imaging unit 5, and is used to receive X-rays carrying information about the specimen 4 to be photographed, and to convert the X-rays into electrical signals for analysis.

[0077] In addition, the rotary cutting device in this embodiment includes a collection unit 6, which is connected between the visualization container 1 and the sample injection unit 2. It is used to draw the photographic specimen into the collection unit 6 for storage through the sample injection unit 2, so as to facilitate subsequent pathological examination and analysis of the photographic specimen.

[0078] The rotary cutting device in this embodiment includes a rotary cutting blade 7, which is used to remove lesions in the human body to form a specimen 4 to be photographed. The rotary cutting blade 7 is provided with a channel. One end of the channel is connected to the outside, and the other end of the channel is connected to the visualization container 1 through a connecting tube 8. The channel can be placed on the specimen 4 to be photographed after removal, and the specimen 4 to be photographed is driven through the channel and the connecting tube 8 by the sample injection unit 2 to further enter the visualization container 1.

[0079] The rotary cutting device in this embodiment includes a control unit 9, which sends control commands to the imaging unit 5, the sample feeding unit 2, and the limiting unit 3 to automate the operation of the rotary cutting device. Alternatively, the rotary cutting device may not include the control unit 9.

[0080] The rotary cutting device in this embodiment includes a display, which is communicatively connected to the detector 502, for displaying the photographed specimen image. The display is also communicatively connected to the control unit 9, and the display is equipped with control buttons so that the user can control the imaging unit 5, the sample introduction unit 2, and the limiting unit 3 by driving the control buttons. As an alternative implementation, the rotary cutting device may not include a display, but the detector 502 may be connected to an external device, such as a computer or mobile phone.

[0081] There are many types of limiting units 3. The following are three specific examples.

[0082] Example 1

[0083] Combination Figure 2 As shown, the size of the receiving cavity matches the size of the specimen 4 in the direction perpendicular to its movement. Based on this, the direction of movement of the specimen 4 can be limited by the receiving cavity, thereby improving the stability of its movement.

[0084] In addition, combined Figure 2 As shown, in this embodiment, the limiting unit 3 includes:

[0085] The first flexible structure 301 is connected between the sample outlet 102 and the sample injection unit 2;

[0086] The first driving structure is located on both sides of the first flexible structure 301 and is used to compress the first flexible structure 301 to adjust the opening of the receiving cavity corresponding to the sample outlet 102.

[0087] The first driving structure can drive the first flexible structure 301 to deform, forming a barrier to the specimen 4 to be photographed, so that the specimen 4 cannot move beyond the position of the visualization container 1, thereby limiting the position of the specimen 4 and achieving the technical effect of improving the working efficiency of the rotary cutting device.

[0088] Of course, in other embodiments, the number of the first driving structure can be adjusted as needed depending on the design of the rotary cutting device. For example, the number of the first driving structure can be one or more than two, all of which are within the protection scope of this utility model.

[0089] In addition, combined Figure 2 As shown, in this embodiment, the first driving structure includes:

[0090] Two moving parts 308 are respectively disposed along the first flexible structure 301. Figure 2 The two sides in the Y-axis direction shown are used to clamp the first flexible structure 301 or move away from the first flexible structure 301;

[0091] The first driving unit is connected to the moving unit 308, and the number of the first driving units corresponds one-to-one with the number of the moving units 308, for driving the moving unit 308 along... Figure 2 The motion along the Y-axis is shown.

[0092] In this embodiment, the first flexible structure 301 is a flexible tube, the moving part 308 is a slider, the slider can move along the Y-axis to drive the first flexible structure 301 to deform, and the first driving part is an electric telescopic rod.

[0093] Specifically, one end of the moving part 308 is spaced apart from the first flexible structure 301, and the other end of the moving part 308 is fixedly connected to the first driving part. The first driving part drives the two moving parts 308 to clamp the first flexible structure 301 to block the movement path of the specimen 4 to be photographed. The first driving part can also drive the two moving parts 308 away from the first flexible structure 301. At this time, the first flexible tube returns to its original shape, and the specimen 4 to be photographed can enter the collection unit 6 through the first flexible tube.

[0094] Of course, in other embodiments, the types of the first driving unit and the moving unit 308 can be adjusted according to the different designs of the rotary cutting device. For example, the first driving unit can be a motor, and the moving unit 308 can be a worm gear transmission structure. At the same time, in other embodiments, the number of moving units 308 can also be adjusted according to the different designs of the rotary cutting device. For example, the number of moving units 308 can be one or more, all of which are within the protection scope of this embodiment.

[0095] Furthermore, in this embodiment, the limiting unit 3 includes a second flexible structure 302, which is connected between the sample inlet 101 and the rotary cutter 7. Based on this, the second flexible structure 302 can elastically deform according to the different dimensions of the connecting end of the rotary cutter 7, thereby achieving the technical effect of improving the connection stability between the connecting end of the rotary cutter 7 and the second flexible structure 302. Alternatively, the rotary cutting device may not include the second flexible structure 302.

[0096] Example 2

[0097] Combination Figures 3 to 5 As shown, along the direction perpendicular to the movement of the specimen 4, the size of the receiving cavity is larger than the size of the specimen 4, and the dimensions of the receiving cavity on both sides along the Y-axis are slightly larger than the dimensions of the specimen 4 along the Y-axis. Based on this, the specimen 4 is prevented from being visualized along the direction of the container 1 during photography. Figure 3 The two sidewalls in the Y-axis direction shown are located within the imaging range of the imaging unit 5, which affects the imaging accuracy of the specimen 4 to be photographed, thereby achieving the technical effect of improving the imaging accuracy of the specimen 4 to be photographed.

[0098] Combination Figure 3 As shown, the visual container 1 has a first receiving groove on one side, and the limiting unit 3 includes:

[0099] The first limiting structure 303 is located on one side of the visualization container 1. One end of the first limiting structure 303 passes through the first receiving groove and is used to adjust the size of the receiving cavity along the direction of movement perpendicular to the specimen 4 to be photographed under the action of external force, so as to limit the position of the specimen 4 to be photographed.

[0100] The second driving structure is connected to the other end of the first limiting structure 303 and is used to drive the first limiting structure 303 to move in order to adjust the opening of the receiving cavity corresponding to the sample outlet 102.

[0101] Specifically, the length direction of the receiving cavity is set parallel to the X-axis. The specimen 4 to be photographed moves in the direction parallel to the X-axis. The first limiting structure 303 is driven to move in the Y-axis direction by the second driving structure. The degree of obstruction of the receiving cavity by the first limiting structure 303 is used to adjust the opening of the receiving cavity corresponding to the sample outlet 102, so as to limit the position of the specimen 4 to be photographed as needed.

[0102] In this embodiment, the first limiting structure 303 can be a baffle, and the dimension of the first limiting structure 303 located within the receiving cavity along the X-axis is smaller than the dimension of the first limiting structure 303 not located within the receiving cavity along the X-axis. Based on this, not only can the thickness of the first limiting structure 303 within the receiving cavity be reduced to save material, but the contact area between the first limiting structure 303 and the second driving structure can also be increased, thereby improving the connection stability between the first limiting structure 303 and the second driving structure. In other embodiments, the shape of the first limiting structure 303 can be adjusted depending on the design of the rotary cutting device.

[0103] As an alternative implementation, the first receiving groove may not be provided on one side of the visualization container 1, and one end of the first limiting structure 303 may be inserted at the connection position between the sample outlet 102 and the sample inlet unit 2. That is, the first limiting structure 303 is fitted to the sample outlet 102 and the sample inlet unit 2, which can also achieve the technical effect of adjusting the position of the imaging unit.

[0104] Of course, in other embodiments, the position of the receiving cavity, the position of the first limiting structure 303, the number of the first receiving slots, and the number of the first limiting structures 303 can be adjusted as needed.

[0105] Preferably, when both ends of the first limiting structure 303 along the Y-axis and both ends along the Z-axis are fitted to the inner wall of the visualization container 1, the first limiting structure 303 is provided with a flow hole 304, which is connected to the sample inlet 101 and the sample outlet 102. Based on this, when the first limiting structure 303 obstructs the specimen 4 to be photographed, the sample inlet unit 2 can drive the specimen 4 to move to the position of the first limiting structure 303 to perform photographic imaging.

[0106] Of course, in other embodiments, depending on the design of the rotary cutting device, along Figure 6 At least one end of the Z-axis and Y-axis directions shown is provided with the first limiting structure 303 spaced apart from the inner wall of the visualization container 1. At this time, the flow hole 304 is not provided. The connection between the sample inlet 101 and the sample outlet 102 can still be achieved through this gap.

[0107] As an alternative implementation, the first limiting structure 303 can be provided with a flow hole 304, and the first limiting structure 303 can also be positioned along... Figure 6 At least one end of the Z-axis and Y-axis directions shown is spaced apart from the inner wall of the visualization container 1.

[0108] In addition, in this embodiment, the second driving structure includes:

[0109] Support structure 309;

[0110] The elastic part 307 is connected at one end to the support structure 309 and at the other end to the other end of the first limiting structure 303;

[0111] The second drive unit is connected to the elastic part 307 and is used to adjust the elastic force of the elastic part 307.

[0112] The second driving part drives the elastic part 307 to be in a compressed state, that is, the elastic part 307 can drive the first limiting structure 303 to move in the direction of increasing the opening of the receiving cavity. When the second driving part no longer drives the elastic part 307 to be in a compressed state, under the action of elastic force, the elastic part 307 drives the first limiting structure 303 to be in a state of blocking the receiving cavity, so that the first limiting structure 303 can limit the position of the photographic specimen 4.

[0113] Alternatively, the second driving structure can be an electric telescopic rod, which can also drive the first limiting structure 303 to move along the Y-axis.

[0114] In this embodiment, the second driving unit includes:

[0115] A magnetic component is located at the other end of the first limiting structure 303;

[0116] An electromagnetic component is provided on the side of the support structure 309 near the elastic part 307, and is used to generate magnetism when energized to attract the magnetic component, and to separate the magnetic component when the electromagnetic property is cut off.

[0117] When the electromagnetic component is magnetic, it can attract the magnetic component, causing the first limiting part to move along the Y-axis direction to increase the opening of the receiving cavity. When the electromagnetic component is not magnetic, the elastic force of the elastic part 307 drives the first limiting part to move along the Y-axis direction to decrease the opening of the receiving cavity, so as to adjust the opening of the receiving cavity.

[0118] Of course, in other embodiments, the structure of the second drive unit can be adjusted according to the design of the rotary cutting device. For example, the second drive unit includes a first electric telescopic rod and a second electric telescopic rod. The first electric telescopic rod extends and retracts along the Y-axis, and the second electric telescopic rod extends and retracts along the X-axis. The second electric telescopic rod is located between the first electric telescopic rod and the visualization container 1. The fixed end of the first electric telescopic rod is connected to the support structure 309, and the telescopic end of the first electric telescopic rod is connected to the fixed end of the second electric telescopic rod. The movable end of the second electric telescopic rod is located on one side of the elastic part 307. When it is necessary to drive the elastic part 307 into a compressed state, the first electric telescopic rod drives the second electric telescopic rod to extend, and the second electric telescopic rod extends into the elastic part 307. Then, the first electric telescopic rod drives the second electric telescopic rod to retract away from the visualization container 1, so that the elastic part 307 is in a compressed state. When it is necessary for the elastic part 307 to be in a non-compressed state, the second electric telescopic rod retracts, and the elastic part 307 can drive the movement of the first limiting structure 303 under elastic force.

[0119] The specific working process of the limiting unit 3 in this embodiment is as follows:

[0120] Before the sample introduction unit 2 drives the specimen 4 to be photographed into the visualization container 1 through the channel of the rotary cutter 7, the electromagnetic component is de-energized, and the magnetic component drives the first limiting structure 303 to block the first receiving cavity. The sample introduction unit 2 forms an adsorption airflow through the flow hole 304, and the position of the specimen 4 to be photographed can be limited by the first limiting structure 303. After the imaging unit 5 photographs the specimen 4, the electromagnetic component is energized, and the magnetic component drives the first limiting structure 303 to increase the opening of the receiving cavity, so as to place the specimen 4 to be photographed into the collection unit 6. Then the electromagnetic component is de-energized, and the cycle repeats.

[0121] Example 3

[0122] Combination Figure 6 and Figure 7 As shown, the size of the receiving cavity is larger than the size of the specimen 4 to be photographed, and the dimensions of the receiving cavity along the Y-axis are much larger than the dimensions of the specimen 4 along the Y-axis. Based on this, the specimen 4 is prevented from being visualized along the Y-axis during the photographing process. Figure 6 The two sidewalls in the Y-axis direction affect the photographic imaging results of the specimen 4 to be photographed, thereby achieving the technical effect of improving the accuracy of the photographic imaging of the visualization container 1.

[0123] Combination Figure 6 As shown, the visual container 1 has a first receiving groove on one side, and the limiting unit 3 includes:

[0124] The first limiting structure 303 is provided on one side of the visualization container 1. One end of the first limiting structure 303 passes through the first receiving groove and is used to adjust the size of the visualization container 1 along the direction of movement perpendicular to the direction of movement of the specimen 4 to be photographed under the action of external force, so as to limit the direction of movement of the specimen 4 to be photographed.

[0125] The second driving structure is connected to the other end of the first limiting structure 303 and is used to drive the first limiting structure 303 to move in order to adjust the opening of the receiving cavity corresponding to the sample outlet 102.

[0126] Specifically, the length direction of the receiving cavity is set parallel to the X-axis. The specimen 4 to be photographed moves in the direction parallel to the X-axis. The first limiting structure 303 is driven to move in the Y-axis direction by the second driving structure. The degree of obstruction of the receiving cavity by the first limiting structure 303 is used to adjust the opening of the receiving cavity corresponding to the sample outlet 102, so as to limit the position of the specimen 4 to be photographed as needed.

[0127] In this embodiment, the first limiting structure 303 can be a baffle, and the dimension of the first limiting structure 303 located within the receiving cavity along the X-axis is smaller than the dimension of the first limiting structure 303 not located within the receiving cavity along the X-axis. Based on this, not only can the thickness of the first limiting structure 303 within the receiving cavity be reduced to save material, but the contact area between the first limiting structure 303 and the second driving structure can also be increased, thereby improving the connection stability between the first limiting structure 303 and the second driving structure. In other embodiments, the shape of the first limiting structure 303 can be adjusted depending on the design of the rotary cutting device.

[0128] As an alternative implementation, the first receiving groove may not be provided on one side of the visualization container 1, and one end of the first limiting structure 303 may be inserted at the connection position between the sample outlet 102 and the sample inlet unit 2. That is, the first limiting structure 303 is fitted to the sample outlet 102 and the sample inlet unit 2, which can also achieve the technical effect of adjusting the position of the imaging unit.

[0129] Of course, in other embodiments, the position of the receiving cavity, the position of the first limiting structure 303, the number of the first receiving slots, and the number of the first limiting structures 303 can be adjusted as needed.

[0130] Preferably, when both ends of the first limiting structure 303 along the Y-axis and both ends along the Z-axis are fitted to the inner wall of the visualization container 1, the first limiting structure 303 is provided with a flow hole 304, which is connected to the sample inlet 101 and the sample outlet 102. Based on this, when the first limiting structure 303 obstructs the specimen 4 to be photographed, the sample inlet unit 2 can drive the specimen 4 to move to the position of the first limiting structure 303 to perform photographic imaging.

[0131] Of course, in other embodiments, depending on the design of the rotary cutting device, along Figure 6 At least one end of the Z-axis and Y-axis directions shown is provided with the first limiting structure 303 spaced apart from the inner wall of the visualization container 1. At this time, the flow hole 304 is not provided. The connection between the sample inlet 101 and the sample outlet 102 can still be achieved through this gap.

[0132] As an alternative implementation, the first limiting structure 303 can be provided with a flow hole 304, and the first limiting structure 303 can also be positioned along... Figure 6 At least one end of the Z-axis and Y-axis directions shown is spaced apart from the inner wall of the visualization container 1.

[0133] Combination Figure 6 and Figure 7 As shown, the visual container 1 has two second receiving slots on each side, and the limiting unit 3 includes:

[0134] The second limiting structure 305 is located along the visual container 1. Figure 6 On both sides of the Y-axis direction shown, for example, two second limiting structures 305 are provided on each side. The second limiting structures 305 are used to adjust the size of the visualization container 1 along the direction of movement perpendicular to the specimen 4 to be photographed under the action of external force, so as to limit the direction of movement of the specimen 4 to be photographed.

[0135] The third driving structure is located outside the visualization container 1 and connected to the second limiting structure 305, used to drive the second limiting structure 305 along... Figure 6 The motion along the Y-axis is shown.

[0136] The second limiting structure 305 is driven by the third driving structure to move along the Y-axis. Based on this, even if the dimensions of the receiving cavity on both sides along the Y-axis are much larger than the dimensions of the specimen 4 to be photographed along the Y-axis, the second limiting structure 305 will limit the movement direction of the specimen 4 to be photographed, so that the specimen 4 to be photographed can move from the sample inlet 101 to the sample outlet 102, thereby achieving the technical effect of improving the accuracy of the movement direction of the specimen 4 to be photographed.

[0137] In this embodiment, the third driving structure is an electric telescopic rod, and the second limiting structure 305 is a limiting plate. Of course, in other embodiments, the type of the third driving structure can be adjusted as needed; for example, the third driving structure can also be a ball screw drive structure. In other embodiments, the shape of the second limiting structure 305 can also be adjusted.

[0138] Furthermore, each of the two sides of the visualization container 1 along the Y-axis is provided with a third driving structure, and each third driving structure is simultaneously connected to the two second limiting structures 305 of that side.

[0139] Of course, in other embodiments, the number of third driving structures can correspond one-to-one with the number of second limiting structures 305. Compared with other embodiments, this embodiment can reduce the number of third driving structures, thereby achieving the technical effect of saving the design cost of the rotary cutting device.

[0140] As an alternative implementation, the second receiving groove may not be provided on one side of the visualization container 1, and one end of the second limiting structure 305 may be inserted at the connection position between the sample inlet 101 and the connecting tube 8. That is, the second limiting structure 305 is fitted to the sample inlet 101 and the connecting tube 8, which can also achieve the technical effect of adjusting the position of the imaging unit.

[0141] Preferably, the visualization container 1 is provided with at least one baffle structure 306, and the second limiting structure 305 passes through the second receiving groove and is connected to the baffle structure 306. It is used to adjust the distance between the baffle structure 306 and the inner wall of the visualization container 1, or the distance between the baffle structures 306 that are arranged opposite each other, along the direction of movement perpendicular to the specimen 4 to be photographed, under the action of external force.

[0142] In this embodiment, two stop arm structures 306 can be provided. Each stop arm structure 306 is arc-shaped. One stop arm structure 306 is simultaneously connected to two second limiting structures 305 on one side, and the other stop arm structure 306 is simultaneously connected to two second limiting structures 305 on the other side. The stop arm structures 306 increase the contact area between the second limiting structures 305 and the specimen 4 to be photographed, thereby improving the stability of the positional limitation of the specimen 4. Alternatively, the stop arm structure 306 can be square or other shapes; no further limitations are imposed here.

[0143] Of course, in other embodiments, depending on the design of the rotary cutting device, the second limiting structure 305 may be located on one side or more than both sides of the visual container 1, all of which are within the scope of protection of this application. The number of stop arm structures 306 can be adjusted as needed.

[0144] The specific working process of the limiting unit 3 in this embodiment is as follows:

[0145] First, before the sample introduction unit 2 drives the specimen 4 to be photographed to enter the visualization container 1 through the channel of the rotary cutter 7, the third driving structure drives the second limiting structure 305 to move to the point where the interval between the two different side stop arm structures 306 corresponds to the size of the specimen 4 to be photographed, so as to limit the movement path of the specimen 4 to be photographed.

[0146] Next, the second drive structure can drive the first limiting structure 303 to move in the direction of reducing the opening of the receiving cavity.

[0147] Subsequently, the sample introduction unit 2 forms an adsorption gas flow through the flow hole 304, and the position of the photographic specimen 4 can be limited by the first limiting structure 303.

[0148] Next, the third driving structure drives the second limiting structure 305 to move away from the specimen 4 to be photographed, so that the second limiting structure 305 moves outside the photographic range. After the photographic imaging unit 5 photographs the specimen 4, the third driving structure drives the second limiting structure 305 to move closer to the specimen 4 to be photographed, thus limiting the direction of movement of the specimen 4. The second driving structure drives the first limiting structure 303 to move in the direction of increasing the opening of the receiving cavity, so as to place the specimen 4 to be photographed into the collecting unit 6. Then, it is determined whether the position of the second limiting structure 305 needs to be adjusted as needed. This cycle is repeated to complete the photographing of the specimen 4.

[0149] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
