[0014] In one embodiment, the mainframe frame further includes a fourth outer surface, the fourth outer surface is arranged relatively spaced from the second outer surface, and the fourth outer surface is connected to the first outer surface and the third outer surface respectively;

[0015] The first shell portion and the third shell portion are respectively provided with an extension portion, and the edges of the first shell portion, the second shell portion, the third shell portion and the extension portion on the same side jointly form a sliding entrance for the host frame to be placed into the placement space, and when the host outer frame closes the opening, each of the extension portions is in contact with the fourth outer surface.

[0028] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment, a biopsy device is provided, including a biopsy sampling device (not shown) and a biopsy host 10. The biopsy host 10 is adapted to the biopsy sampling device, so that the biopsy sampling device can be provided with power, control signals, etc. through the biopsy host 10, and the biopsy sampling device can be used to perform biopsy sampling on the affected area. In addition, when replacing or repairing the electrical components inside the biopsy host 10, the maintenance is simple and the maintenance efficiency is high.

[0030] It should be noted that the biopsy host 10 can also be connected to the biopsy sampling device through an air circuit, that is, the negative pressure system on the biopsy host 10 is connected to the biopsy sampling device through a negative pressure pipeline to provide sampling negative pressure, and the sampling container 400 can be a part of the negative pressure system.

[0031] It should also be explained that the biopsy sampling device can be an existing rotary cutting sampling biopsy needle, or an existing electrocoagulation biopsy needle that has both rotary cutting sampling and electrocoagulation functions. In addition, the use of an existing ejection sampling biopsy needle is not excluded, which can be an existing device and will not be described in detail here.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, a biopsy host 10 is provided, including a host frame 100 and a host outer frame 200 .

[0033] The host frame 100 can be used as a main structure and can be in a box-like or box-like structure. Figure 2 As shown, the mainframe frame 100 has at least three different outer surfaces, and the mainframe frame 100 is provided with a mounting cavity 110, so that the electrical components can be mounted on the outer side wall of the mounting cavity 110 by screwing or clamping. Moreover, the mounting cavity 110 at least penetrates two adjacent outer surfaces to form an opening, that is, the opening of the mounting cavity 110 at least penetrates two adjacent outer surfaces.

[0034] It should be noted that the opening of the installation cavity 110 may refer to an outlet connecting the installation cavity 110 with the outside, and other non-electrical components such as a vacuum pump and a valve may also be placed in the installation cavity 110 .

[0035] The host outer frame 200 may be in the shape of a shell or a casing, and the host outer frame 200 is connected to the host frame 100 by an active connection such as hinge or sliding fit, or by a detachable connection such as snap connection or plug-in connection, so that the host outer frame 200 can close or open an opening.

[0036] like Figure 1 and Figure 2 As shown, specifically, when the mainframe outer frame 200 moves relative to the mainframe frame 100 to an open position, the installation cavity 110 can be opened, so that the opening of the installation cavity 110 is exposed, and the installation cavity 110 is connected to the outside; when the mainframe outer frame 200 moves relative to the mainframe frame 100 to a closed position, the installation cavity 110 can be closed, so that the opening of the installation cavity 110 is closed, and the installation cavity 110 is isolated from the outside.

[0037] Optionally, the edge profile of the host frame 200 matches the edge profile of the installation cavity 110 , so that the host frame 200 can effectively close the opening of the installation cavity 110 to form a closed space to protect the electrical components.

[0038] In the above-mentioned embodiment of the biopsy host 10, when in normal use, the host outer frame 200 is in a closed position relative to the host frame 100 and the opening of the installation cavity 110 is closed, so that the electrical components installed in the installation cavity 110 are encapsulated and provided with protection. When it is necessary to maintain the electrical components, the opening of the installation cavity 110 can be opened by simply moving the host outer frame 200 relative to the host frame 100 from the closed position to the open position, so that the installation cavity 110 is connected to the outside world through the opening, and then the electrical components can be maintained. In addition, since the installation cavity 110 at least penetrates two adjacent outer surfaces of the host frame 100 to form an opening, when the host outer frame 200 is in an open position and the installation cavity 110 is connected to the outside world through the opening, the connection area between the installation cavity 110 and the outside world is large enough to leave a large enough operation space or disassembly space, so that maintenance is simple and maintenance efficiency is improved.

[0039] It should be noted that the mounting cavity 110 passes through at least two adjacent outer surfaces; it can be two outer surfaces, for example, two adjacent outer surfaces; it can also be three outer surfaces, for example, two relatively spaced outer surfaces and an outer surface located between the two relatively spaced outer surfaces and connected to both relatively spaced outer surfaces; it can also be four outer surfaces, for example, two relatively spaced outer surfaces and two outer surfaces located between the two relatively spaced outer surfaces and connected to both relatively spaced outer surfaces.

[0040] like Figure 2As shown, in one embodiment, the mainframe frame 100 includes a first outer surface 120, a second outer surface 130 and a third outer surface 140 connected in sequence. The first outer surface 120 and the third outer surface 140 are arranged relatively spaced apart, and the installation cavity 110 penetrates the first outer surface 120, the second outer surface 130 and the third outer surface 140 to form an opening. In this way, when the mainframe outer frame 200 is in the open position and the installation cavity 110 is connected to the outside through the opening, the connection area between the installation cavity 110 and the outside is large enough to leave a large enough operation space or disassembly space, so that the electrical components can be maintained from three different directions, which makes the maintenance simple and improves the maintenance efficiency.

[0041] like Figure 2 As shown, further, the opening has a first side edge 121 formed on the first outer surface 120, a second side edge 131 formed on the second outer surface 130, and a third side edge 141 formed on the third outer surface 140. In this way, when the host outer frame 200 moves from the closed position to the open position relative to the host frame 100 and opens the opening of the installation cavity 110, the electrical components in the installation cavity 110 can be maintained from at least one of the first side edge 121, the second side edge 131 and the third side edge 141, making the maintenance simpler and improving the maintenance efficiency. Moreover, the host outer frame 200 includes a first housing portion 210 arranged corresponding to the first side edge 121, a second housing portion 220 arranged corresponding to the second side edge 131, and a third housing portion 230 arranged corresponding to the third side edge 141, so that the edge contour shape of the host outer frame 200 matches the edge contour of the opening of the installation cavity 110, so that the host outer frame 200 can effectively close the opening of the installation cavity 110 to form a closed space and protect the electrical components installed in the installation cavity 110. At the same time, at least one of the first housing portion 210, the second housing portion 220, and the third housing portion 230 is detachably connected to the host frame 100, so that the entire host outer frame 200 can be flexibly moved between an open position and a closed position relative to the host frame 100, thereby flexibly opening or closing the opening of the installation cavity 110.

[0042] like Figure 2As shown, in one embodiment, the first housing portion 210, the second housing portion 220, and the third housing portion 230 are enclosed to form an insertion space 240 for the host frame 200 to be inserted. Moreover, when the host frame 200 is closed, the first housing portion 210 is in contact with the first outer surface 120, the second housing portion 220 is in contact with the second outer surface 130, and the third housing portion 230 is in contact with the third outer surface 140. In this way, the opening of the installation cavity 110 can be effectively closed to form a closed space, and the electrical components installed in the installation cavity 110 can be effectively sealed and protected to prevent foreign objects from entering and interfering with or affecting the operation of the electrical components.

[0043] like Figure 2 As shown, in one embodiment, the mainframe frame 100 further includes a fourth outer surface 150. The fourth outer surface 150 is arranged to be spaced apart from the second outer surface 130, and the fourth outer surface 150 is connected to the first outer surface 120 and the third outer surface 140 respectively. At the same time, the first shell portion 210 and the third shell portion 230 are each provided with an extension portion 250, and the edges of the first shell portion 210, the second shell portion 220, the third shell portion 230 and the extension portion 250 on the same side jointly form a sliding entrance 160 for the mainframe frame 100 to be placed in the placement space 240, so that the entire mainframe outer frame 200 can flexibly slide between an open position and a closed position relative to the mainframe frame 100, thereby flexibly opening or closing the opening of the installation cavity 110. Moreover, when the main frame 200 is closed, each extension portion 250 is in contact with the fourth outer surface 150, so that the opening of the installation cavity 110 can be effectively closed to form an enclosed space and the electrical components installed in the installation cavity 110 can be effectively sealed and protected to prevent foreign objects from entering and interfering with or affecting the operation of the electrical components.

[0044] The extension portion 250 may be in the form of a flange or the like.

[0045] like Figure 2 As shown, in a specific embodiment, the fourth outer surface 150 is the bottom surface of the mainframe frame 100, and the extension portion 250 is the bottom of the mainframe outer frame 200. In this way, through the sliding fit between the bottom and the bottom surface, the entire mainframe outer frame 200 can flexibly slide between an open position and a closed position relative to the mainframe frame 100, thereby flexibly opening or closing the opening of the installation cavity 110.

[0046] In one embodiment, at least one of the extensions is provided with a first connection hole, and the mainframe 100 is provided with a second connection hole corresponding to and communicating with the first connection hole. In addition, the biopsy mainframe 10 further includes a connection member, which is tightly matched with the first connection hole and the second connection hole. In this way, when the mainframe outer frame 200 moves to a closed position relative to the mainframe 100, the first connection hole and the second connection hole are aligned with each other, and then the first connection member is tightly matched with the first connection hole and the second connection hole, so that the mainframe outer frame 200 and the mainframe 100 are stably and reliably connected and fixed.

[0047] The fastening cooperation between the connecting member and the first connecting hole and the second connecting hole can be achieved by threaded connection between a screw and a threaded hole, or by plugging cooperation between a pin and a socket.

[0048] like Figure 2 As shown, in addition, the mainframe 100 is further provided with a placement cavity 170 isolated from the installation cavity 110, that is, the placement cavity 170 and the installation cavity 110 are not connected to each other, so as to prevent the liquid from damaging the electrical components in the installation cavity 110. The placement cavity 170 is used to place the sampling container 400, and the biopsy host 10 also includes an outer cover 300, which is connected to the mainframe 100 by a rotating shaft, a hinge, etc. to realize a movable connection or a detachable connection by a card connection or a plug connection, so as to open or close the placement cavity 170. When in use, the sampling container 400 can be placed in the placement cavity 170 of the mainframe 100 first, and then the outer cover 300 is connected to the mainframe 100 by a movable connection or a detachable connection so as to close the placement cavity 170, so that the sampling container 400 can be placed in a closed space to protect the sampling container 400.

[0049] Furthermore, the outer cover 300 is constructed as a visual structure, through which the status in the placement cavity 170 can be quickly and intuitively seen from the outside, so that the position of the sampling container 400 can be known in time, so as to efficiently implement the maintenance of the sampling container 400.

[0050] In one embodiment, the outer cover 300 is provided with a transparent or translucent visualization structure, so that the situation in the placement cavity 170 can be seen from the outside through the transparent or translucent visualization structure, and the position of the sampling container 400 corresponding to the biopsy host 10 can be timely known. It should be noted that when the outer cover 300 is transparent, the sampling container 400 can be directly seen clearly from the outside of the biopsy host 10, and even the liquid level position in the sampling container 400 can be seen clearly; when the host outer frame 200 is translucent, the liquid level position in the sampling container 400 may not be seen clearly, but at least the general outline position of the sampling container 400 placed inside can be seen through the host outer frame 200.

[0051] Optionally, the transparent visualization structure can be implemented by transparent materials such as glass, and the translucent visualization structure can be implemented by translucent materials such as polypropylene.

[0052] Optionally, the placement cavity 170 at least penetrates two adjacent outer surfaces. In this way, the opening of the placement cavity 170 penetrates at least two outer surfaces, making it easy to take and place the sampling container 400 through the opening from at least two angles, avoiding interference and making it easy to take and place.

[0053] It should be noted that "some body" or "some part" can be a part of the corresponding "component", that is, "some body" or "some part" can be integrally formed with the "other parts of the component"; it can also be an independent component that can be separated from the "other parts of the component", that is, "some body" or "some part" can be manufactured independently and then combined with the "other parts of the component" into a whole. The expression of the above-mentioned "some body" or "some part" in this application is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of this application. As long as it contains the above-mentioned features and has the same function, it should be understood as an equivalent technical solution of this application.

[0054] It should be noted that the components included in the "unit", "assembly", "mechanism" and "device" of this application can also be flexibly combined, that is, modular production can be carried out according to actual needs to facilitate modular assembly. The division of the above components in this application is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of this application. As long as the above components are included and have the same functions, it should be understood that it is an equivalent technical solution of this application.

[0055] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The term "and / or" used in the present invention includes any and all combinations of one or more related listed items.

[0056] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0057] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0059] It should be noted that when an element is referred to as being "fixed on", "set on", "fixed on" or "installed on" another element, it can be directly on the other element or there can be a central element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there can be a central element at the same time. Further, when an element is considered to be "fixed transmission connected" to another element, the two can be fixed in a detachable connection manner or in a non-detachable connection, as long as power transmission can be achieved, such as socketing, snap-on, one-piece molding fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0060] It should also be understood that when explaining the connection relationship or positional relationship of elements, although not explicitly described, the connection relationship and positional relationship are interpreted as including an error range, which should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" may mean within one or more standard deviations, which are not limited here.

[0061] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
