[0028] With reference to the accompanying drawings, the above and other features of the present application will become apparent through the following description. In the description and the accompanying drawings, specific embodiments of the present application are specifically disclosed, which show some embodiments in which the principles of the present application can be adopted. It should be understood that the present application is not limited to the described embodiments. On the contrary, the present application includes all modifications, variations and equivalents falling within the scope of the attached claims.

The terms "include", "comprises", "has", etc. refer to the existence of the stated features, elements, components or components, but do not exclude the existence or addition of one or more other features, elements, components or components.

[0030] In the embodiments of the present application, the singular forms "a", "the", etc. may include plural forms and should be broadly understood as "a kind" or "a type" rather than being limited to the meaning of "one"; in addition, the term "said" should be understood to include both singular and plural forms, unless the context clearly indicates otherwise. In addition, the term "according to" should be understood as "at least in part according to...", and the term "based on" should be understood as "at least in part based on...", unless the context clearly indicates otherwise.

[0031] The implementation of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0032] Figure 1 is a schematic diagram of an X-ray imaging system according to an embodiment of the present application; Figure 1 As shown, the X-ray imaging system 100 may be an example of a medical imaging system, which includes a floor device 110, a wall stand device 120, and a detection bed device 130 arranged in a scanning room 101, and a control device 150 arranged in a control room 102. The floor device 110 includes a wall stand 111, a cantilever 112, and an X-ray source assembly 113. The cantilever 112 is used to carry the X-ray source assembly 113, and the cantilever 112 is installed on the wall stand 111.

[0033] Although some embodiments of the present application are described based on a floor-standing X-ray imaging system, the embodiments of the present application are not limited thereto. For example, the medical imaging system may also be other types of X-ray imaging systems, such as a mobile X-ray imaging system, or the medical imaging system may also be other types of imaging systems, such as a computerized tomography (CT) system, a positron emission tomography (PET) system, a magnetic resonance imaging (MRI) system, etc.

[0034] For ease of description, in the present application, the x-axis, y-axis and z-axis are defined as the x-axis and y-axis are located in a horizontal plane and are perpendicular to each other, and the z-axis is perpendicular to the horizontal plane. Specifically, the extension direction of the cantilever 112 or the width direction of the detection bed device is defined as the x-axis, the direction in the horizontal plane perpendicular to the extension direction of the cantilever or the length direction of the detection bed device is defined as the y-axis direction, and the extension direction of the column 111 is defined as the z-axis direction, and the z-axis direction is the vertical direction.

[0035] The floor device 110 further includes a guide rail installed on the floor, which is arranged along the y-axis direction, and the column moves along the guide rail, that is, moves along the y-axis direction. In addition, the cantilever 112 can also move in the vertical direction (that is, the z-axis direction) relative to the column 111. In addition, a driving device can be arranged between the X-ray source assembly 113 and the column 111, and the driving device can drive the X-ray source 113 to rotate with the x-axis as the central axis.

[0036] The X-ray source assembly 113 includes a tube assembly, a beam limiter 114 and a tube control device 115. An X-ray tube is disposed in the tube assembly, and the X-ray tube can generate X-rays and project the X-rays to a desired region of interest ROI of the patient.

[0037] The beam limiter 114 is usually installed below the X-ray tube, and the X-rays emitted by the X-ray tube are irradiated onto the object to be inspected through the opening of the beam limiter 114. The size of the opening of the beam limiter 114 determines the irradiation range of the X-rays, that is, the size of the exposure field of view (FOV). It is well known that X-rays are harmful to the human body, so it is necessary to control the X-rays so that they only irradiate the part of the object to be inspected, that is, the region of interest (ROI).

[0038] The tube control device 115 is installed on the tube assembly. The tube control device 115 includes a user interface such as a display screen and control buttons for performing preparations before shooting, such as patient selection, protocol selection, and positioning.

[0039] The column device 120 includes a first detector assembly 121, a column 122 and a connecting portion (not shown). The connecting portion includes a cantilever connected perpendicularly to the height direction of the column 122 and a rotating bracket installed on the cantilever. The first detector assembly 121 is installed on the rotating bracket. The column device 120 further includes a detector driving device arranged between the rotating bracket and the first detector assembly 121. Under the drive of the detector driving device, the first detector assembly 121 moves along a direction parallel to the height direction of the column 122 on the plane supported by the rotating bracket. The first detector assembly 121 can also be further rotated relative to the cantilever to form a certain angle with the column. The first detector assembly 121 has a plate-like structure, and its direction is variable so that the X-ray incident surface becomes vertical or horizontal according to the incident direction of the X-ray.

[0040] The detection bed device 130 includes a bed board 131 and a second detector assembly (not shown). The selection or use of the first detector assembly 121 and the second detector assembly can be determined based on the patient's shooting part and / or shooting protocol, and can also be determined based on the position of the object to be detected obtained by camera shooting, so as to perform shooting inspections in a supine or standing position. Figure 1 Only an example diagram of the column and the detection bed is shown. Those skilled in the art should understand that columns and / or detection beds of any form or arrangement may be selected, or only columns may be installed. The columns and / or detection beds do not limit the entire scheme of the present application.

[0041] In some embodiments, the control device 150 may include a source controller and a detector controller. The source controller is used to command the X-ray source to emit X-rays for image exposure. The detector controller is used to select a suitable detector from a plurality of detectors and coordinate the control of various detector functions, for example, automatically selecting a corresponding detector according to the position or posture of the object to be detected, or performing various signal processing and filtering functions, specifically, for initial adjustment of the dynamic range, interleaving of digital image data, etc. In some embodiments, the control device 150 may provide power and timing signals for controlling the operation of the X-ray source and the detector.

[0042] In some embodiments, the control device 150 may also be configured to use the digitized signals to reconstruct one or more desired images and / or determine useful diagnostic information corresponding to the patient, wherein the control device 150 may include one or more dedicated processors, graphics processing units, digital signal processors, microcomputers, microcontrollers, application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), or other appropriate processing devices.

[0043] Of course, the medical imaging system may also include other numbers or configurations or forms of control devices, for example, the control device may be local (e.g., co-located with one or more X-ray imaging systems 100, such as in the same facility and / or the same local network); in other implementations, the control device may be remote and therefore only accessible via a remote connection (e.g., via the Internet or other available remote access technology). In a specific implementation, the control device may also be configured in a cloud-like manner and may be accessed and / or used in a manner substantially similar to accessing and using other cloud-based systems.

[0044] The system 100 also includes a storage device (not shown), and the processor can store the digitized signal in the storage. For example, the storage can include a hard disk drive, a floppy disk drive, a CD-ROM read / write drive, a digital universal disk drive, a flash drive, and / or a solid-state memory. The storage can also be integrated with the processor to effectively use the floor space and / or meet the expected imaging requirements.

[0045] The system 100 also includes an input device 160, which may include a form of operator interface such as a keyboard, a mouse, a voice-activated control device, a touch screen (which may also serve as a display device described later), a trackball, or any other suitable input device. The operator may input operation signals / control signals to the control device through the input device 160.

[0046] The system 100 also includes a display device 151 (such as a touch screen or a display screen), which can be used to display an operation interface such as a list of detected objects, a position or exposure setting of the detected objects, and an image of the detected objects.

[0047] In such Figure 1 In the X-ray imaging system shown, the floor device 110 includes the following movements: the column moves along the length direction (y-axis) of the inspection bed, the column rotates, the cantilever drives the X-ray source assembly to move along the vertical direction (z-axis) and the width direction (x-axis), and the angle movement and tilt movement of the tube assembly. Different movements have different functional requirements. For example, in orthopedic examinations, some special positioning is required, and the tilt movement of the tube assembly is particularly necessary.

[0048] Figure 2 This is a schematic diagram of the existing ball tube fixture. Figure 3 This is a schematic diagram of the existing tube. Figure 4 It is a schematic diagram of the existing ball tube assembly, such as Figures 2 to 4 As shown, the ball tube assembly 200 includes a ball tube 201 and a clamp 301 (hoop), the ball tube 201 has two protrusions 202 (two edges), and the clamp 301 is composed of two parts. Figure 4As shown, during installation, the protrusion 202 is placed in the engaging portion 302 of a part of the clamp 3011, and then the remaining part of the clamp 3012 is assembled with the aforementioned part of the clamp to achieve the clamp holding the ball tube, and the ball tube 201 slides and rotates in the clamp 301 while contacting the surface of the clamp 301. The principle of achieving the tilting movement is: after the ball tube is rotated to the required angle, the two knobs 303 are manually screwed into the clamp (threaded connection). Figure 5 is a cross-sectional view of an existing fixture, such as Figure 5 As shown, the front end of the knob 303 will press on the front surface of the protrusion 202, and the ball tube will be subjected to the front pressure, thereby fixing the ball tube to maintain the current movement. When the tilting movement is needed again, the knob is manually loosened and the above operation is repeated.

[0049] Assuming that the current thread is M8, when the knob 303 is tightened, the required torque is 24 Nm, and the knob radius is usually around 15 mm (when the knob is rotated by holding it with fingers or hands, the lever arm = 0.015 m), which means that the finger force should reach 24 / 0.015 = 1600 N to tighten the knob, which is impossible for a normal person's fingers or hands to rotate. Therefore, there is always the problem of loose and misaligned tubes.

[0050] In addition, space limitations mean that the diameter of the knob cannot be too large. Therefore, the above force cannot be reduced by increasing the radius, which also means that it is inconvenient to hold with fingers or hands and is not ergonomic. Moreover, the operation of the tightening button requires back and forth operation on both sides of the product, which provides a poor operating experience. When the tube is tilted back to the desired default position, the alignment status needs to be visually confirmed, which is neither accurate nor convenient. In addition, since the tube is subjected to positive pressure when it is locked, it may be damaged.

[0051] In order to solve the above problems or at least similar problems, the embodiments of the present application provide a ball tube locking device, a ball tube assembly and a medical device.

[0052] The following is a detailed description of the embodiments of the present application.

[0053] The present application embodiment provides a ball tube locking device, Figure 6 is a schematic diagram of a ball tube locking device according to an embodiment of the present application, Figure 7 is a cross-sectional view of the ball tube locking device of the embodiment of the present application along the extending direction of the ball tube, Fig.12 : is a schematic diagram of the ball tube locking device and the ball tube assembly of an embodiment of the present application, such as Figure 6 and Figure 7 As shown, the device comprises:

[0054] A ball tube clamp 41, which is used to hold the ball tube and has a through hole 411;

[0055] A pressing block 42 having a receiving portion 421;

[0056] The connecting portion 43 passes through the through hole 411 , and a portion of the connecting portion 43 is accommodated in the accommodating portion 421 . When the connecting portion 43 is rotated, the pressing block 42 presses or moves away from the ball tube to lock or release the ball tube.

[0057] In some embodiments, the structure of the tube can refer to Figure 3 The ball tube 201 in the embodiment of the present invention, the ball tube clamp 41 can be disassembled into a first clamp 412 and a second clamp 413 (for example, the ball tube clamp 41 can be a clamp formed by two half clamps that are joined and connected, and the two half clamps are both semicircular), and the first clamp 412 and the second clamp 413 respectively have a semicircular bending portion (step) 414. When assembling, as shown in FIG. Figure 6 and Figure 7 As shown, the protrusions 202 (two) are placed on the bent portions 414 (two) of the second part of the clamp 413, and then the bent portion of the first part of the clamp 412 is buckled on the protrusions 202 and assembled with the second part of the clamp 413. The bent portion of the tube clamp 41 contacts the protrusion of the tube. The assembled structure is as shown in FIG. Fig.12 As shown, the tube clamp 41 holds the tube.

[0058] In some embodiments, Figure 3 As shown, the protrusion 202 is prismatic, and the prismatic protrusion is arranged along the circumference of the tube sleeve of the ball tube. After the first part of the clamp 412 and the second part of the clamp 413 are assembled, a circular ring-shaped bending portion 414 is formed, and the bending portion 414 is buckled on the protrusion along the circumference of the tube sleeve of the ball tube. The protrusion 202 has a front surface and two side surfaces. The bending portion of the ball tube clamp 41 contacts the front surface and one side surface. The side surface can be a surface close to the outside, so that the ball tube clamp 41 can hold the ball tube.

[0059] In some embodiments, the second clamp 413 is provided with a through hole 411. Figure 7 The through hole 411 extends in the length direction of the latter connecting portion and passes through the second part clamp 413. The opening position of the through hole 411 is away from the front surface of the protrusion. For example, the opening position of the through hole 411 cannot be located on a part of the bending portion 414 of the second part clamp 413 that contacts the outer surface of the aforementioned protrusion.

[0060] In some embodiments, two symmetrical through holes may be provided on the second portion clamp 413 at the positions corresponding to the two protrusions, or only one through hole may be provided on the second portion clamp 413 at the position corresponding to one protrusion, and the embodiments of the present application are not limited thereto.

[0061] In some embodiments, the pressing block 42 has a receiving portion 421, the inner circumference of the receiving portion 421 is threaded, and the through hole and the receiving portion have the same shape, for example, the shape can be circular. During installation, the pressing block can be pressed toward the inner side of the second part of the clamp 413, and the positions of the through hole and the receiving portion are aligned. When the pressing block is pressed toward the inner side of the second part of the clamp 413, a portion of the area of ​​one end of the pressing block contacts the inner surface of the protrusion 202 (the pressing block and the second part of the clamp may have a gap and not contact), that is, two of the three surfaces of the protrusion 202 contact the bending portion 414, and the other surface contacts the pressing block 42. The receiving portion 421 can be a through hole that passes through the pressing block or a groove that does not pass through the pressing block, and the embodiments of the present application are not limited to this.

[0062] In some embodiments, a pressure block may be provided at each of the second part clamps 413 at the positions corresponding to the two protrusions, and the two pressure blocks may be installed at the inner sides of the second part clamps 413 corresponding to the two protrusions, or only one pressure block may be provided at the second part clamp 413 at the position corresponding to one protrusion, and the embodiments of the present application are not limited thereto. The pressure block may be made of a relatively hard material, such as metal, and examples are not given one by one here.

[0063] In some embodiments, the connecting portion 43 may be in the shape of an elongated strip, one end of which is provided with a thread matching the thread on the inner circumference of the accommodation portion. Figure 8 is a schematic diagram of the connection portion 43 of an embodiment of the present application, such as Figure 8 As shown, the connecting portion 43 has a first column 61 and a second column 62 which are integrally formed and have different outer diameters. The cross-sectional size of the first column 61 is the same as that of the through hole and the receiving portion, and a part (or all) of the first column 61 has threads matching the threads of the receiving portion, and the rest is smooth. When the pressing block is pressed toward the inner side of the second part of the clamp 413, the first column 61 first passes through the through hole 411, the first column 61 with threads enters the receiving portion, and the smooth part enters the through hole. When the receiving portion is a through hole that passes through the pressing block, one end of the first column 61 can pass through the receiving portion (penetrate the pressing block), and the rest of the first column 61 is accommodated in the receiving portion. When the receiving portion is a groove that does not pass through the pressing block, the first column 61 will not penetrate the pressing block, and the first column 61 is completely accommodated in the receiving portion. The cross-sectional area of ​​the second column portion 62 may be circular or other shapes, and the embodiment of the present application is not limited thereto, as long as 62 can rotate in the through hole. However, the cross-sectional area of ​​the second column portion 62 is greater than the cross-sectional area of ​​the first column portion 61 , and therefore, the second column portion 62 will not enter into the through hole.

[0064] The working principle of the ball tube locking device is described below.

[0065] In some embodiments, after the tube is rotated to a desired angle, the second column 62 of the connection portion 43 is rotated in the first direction, and the thread of the first column 61 is connected to the thread of the accommodating portion. After rotating a certain angle, the force of the thread engagement causes the pressing block to press on the inner surface of the protrusion, that is, the pressing block will apply pressure to the inner surface of the protrusion, and the pressing block and the tube clamp will clamp the protrusion, thereby fixing the tube to maintain the current angle to lock the tube. When tilting movement is required again, the second column 62 of the connection portion 43 is rotated in a second direction opposite to the first direction, the thread is unlocked, and the pressing block will move away from the inner surface of the protrusion to release the tube, and the above operation is repeated. The above-mentioned first direction can be upward rotation, and the second direction can be downward rotation, or vice versa, which is specifically related to the rotation direction of the thread, and the embodiments of the present application are not limited thereto.

[0066] Other variations of the ball tube locking device of the embodiment of the present application are described below.

[0067] In some embodiments, the ball tube locking device further includes: a buffer component 45 located between the pressing block and the protrusion. Fig. 9 Schematic diagram of the block structure of the embodiment of the present application. Fig. 9 As shown, the pressing block 42 has not only a receiving portion 421 (taking a through hole as an example), but also a groove 422 is provided on the aforementioned part of the area (the area in contact with the inner side of the protrusion), and the buffer component 45 can be embedded in the groove 422 and fixed in the groove by glue or other means. When the pressing block is pressed on the inner side of the second part of the clamp 413, the buffer component 45 contacts the inner surface of the protrusion. The buffer component 45 can be made of wear-resistant materials such as plastic, but the embodiment of the present application is not limited to this. Through the buffer component, the friction force can be increased, the wear resistance can be improved, and the damage to the protrusion of the tube due to excessive pressure can be avoided. The locking ability is also improved through the friction force.

[0068] In some embodiments, Figure 7 and Fig. 9 As shown, the ball tube clamp also has a first guide hole 415, and the pressing block also has a second guide hole 423; the pressing block also has a guide component 46; a part of the guide component 46 is located in the first guide hole, and the other part is located in the second guide hole. The guide component 46 is integrated with the pressing block 42, and the other part of the guide component 46 is fixed in the second guide hole. During installation, after the guide component on the pressing block is inserted into the first guide hole, the pressing block is pressed against the inner surface of the protrusion. The guide component 46 can avoid the displacement of the position of the pressing block, so that the pressing block is away from or close to the inner surface of the protrusion in the length direction of the connecting part. The guide component can be made of metal or plastic, and the embodiments of the present application are not limited to this.

[0069] In some embodiments, a groove 416 is further provided on the side of the tube fixture 41 (the second part fixture 413) that contacts the pressing block. Fig.13 Schematic diagram of the groove on the ball tube fixture 41 of the embodiment of the present application, as shown in FIG. Fig.13 As shown, the shape of the groove 416 is the same as that of the pressing block, and during installation, the pressing block can be pressed into the groove 416. The limiting function of the groove 416 can prevent the position of the pressing block from being offset, so that the pressing block is away from or close to the inner surface of the protrusion in the length direction of the connecting portion. The groove 416 and the guide component 46 can be implemented separately or in combination, and the embodiment of the present application is not limited thereto.

[0070] In some embodiments, the ball tube locking device further includes: a holding portion 47, which is fixed to the other end of the connecting portion and is used to rotate the connecting portion. Fig.10 Schematic diagram of the holding portion of the embodiment of the present application. Fig.10 As shown, the grip portion has a through hole 471 with the same cross-sectional shape as the other end of the connection portion, and the other end of the connection portion is inserted into the through hole 471. The grip portion can be a structure similar to a wrench, and its length can be determined as needed, but the embodiment of the present application is not limited to this. By rotating the connection portion through the grip portion, the longer length of the grip portion is equivalent to increasing the force arm, thereby applying a smaller force when the ball tube is locked, which can improve convenience.

[0071] In some embodiments, Figure 8 As shown, the cross section of the other end of the connecting portion (second column portion 62) is polygonal. For example, it can be a quadrilateral, a hexagon, or an octagon. The cross section of the through hole 471 is the same as the cross section of the other end of the connecting portion. Thus, the polygonal edge can position the holding portion and prevent the holding portion from falling off from the circumference of the connecting portion.

[0072] In some embodiments, the holding portion may also be provided with a fixing hole 472, which is threaded. When the other end of the connecting portion is inserted into the through hole 471, the screw is screwed into the fixing hole. The screw will apply pressure to the plane where one side of the second column polygon is located, and the holding portion is positioned in the length direction of the connecting portion, thereby further preventing the holding portion from falling off from the length direction of the connecting portion and preventing the holding portion from being lost. This is only an example, and the embodiments of the present application are not limited to this. For example, the holding portion can also be fixed by glue bonding, etc., which will not be exemplified here. According to the principle of thread engagement, when the thread is fully tightened, the rotation angle is approximately 40°-50°. Therefore, when installing, the holding portion can be placed in a suitable position (a position convenient for hand operation) first, and then the screw can be screwed into the fixing hole.

[0073] In some embodiments, a connection part and a holding part may be provided, and the connection part and the holding part may be provided at a fixture position corresponding to a protrusion, passing through a through hole, and the specific side where they are provided may be determined according to the position of the column. Alternatively, two connection parts and two holding parts may be provided, respectively provided at the fixture positions corresponding to the two protrusions, and the embodiments of the present application are not limited thereto.

[0074] In some embodiments, a connecting portion and two holding portions may be provided. The connecting portion may be extended and pass through two through holes at the clamp positions corresponding to the two protrusions, and also need to pass through the receiving portion of the pressing block (the receiving portion is a through hole). The two holding portions are respectively provided at the two ends of the connecting portion, and the structures of the two ends are similar, such as Fig.11 The embodiment shown in the figure will not be described in detail here. The difference from the previous embodiment is that the thread of the connecting part is no longer located at one end of the connecting part, but is located closer to the middle. The locking principle is the same as the previous embodiment. By providing two holding parts, the tube can be locked or released from two directions.

[0075] The assembly process of the ball tube locking device is described below in combination with the above components.

[0076] During assembly, the tube protrusion 202 is placed on the bent portion 414 of the second part of the clamp 413, and then the bent portion of the first part of the clamp 412 is buckled on the protrusion 202 and assembled with the second part of the clamp 413, and the pressing block with the buffer component and the guide component is placed at the corresponding position of the second part of the clamp 413, and the connecting part is inserted into the through hole and the accommodating part on the tube clamp in sequence, and the holding part is placed on the other end of the connecting part. After finding a suitable position, the holding part is fixed on the connecting part. The number of the specific installed pressing blocks, connecting parts, and holding parts can be determined according to needs, and will not be repeated here.

[0077] Through the embodiment of the present application, the connection part passes through the through hole and the accommodating part in sequence. When the connection part is rotated, the pressing block presses or moves away from the tube to lock or release the tube. Its locking force is much greater than that of the existing tube clamp, which greatly reduces the occurrence of misalignment problems, reduces the risk of patients being repeatedly exposed to X-rays, and better meets clinical needs. In addition, there are fewer changes to the existing tube clamp, and there is no need to occupy more space and electrical components, which reduces costs.

[0078] In addition, when the connecting portion is rotated, the pressing block presses or moves away from the protrusion of the tube, so the direction of the locking force is changed compared to the existing tube clamp, and even when the locking force is increased, there is no effect on the tube body.

[0079] In addition, the buffer component located between the pressure block and the protrusion can increase the friction force, improve the wear resistance, avoid damage to the protrusion of the tube due to excessive pressure, and also improve the locking ability through the friction force.

[0080] In addition, the guide member 46 can prevent the position of the pressing block from being offset, so that the pressing block is moved away from or close to the inner surface of the protrusion in the length direction of the connecting portion.

[0081] In addition, the position limiting function of 416 can prevent the position of the pressing block from being offset, so that the pressing block is away from or close to the inner surface of the protruding portion in the length direction of the connecting portion.

[0082] In addition, by rotating the connecting portion through the grip portion, the grip portion has a larger length, which is equivalent to increasing the lever arm. Therefore, when the ball tube is locked, a smaller force is applied, which can improve convenience.

[0083] In addition, the cross section of the other end of the connecting portion is polygonal. The polygonal edges can position the holding portion and prevent the holding portion from falling off from the circumference of the connecting portion.

[0084] In addition, the holding portion is positioned in the length direction of the connecting portion through the fixing hole on the holding portion, thereby further preventing the holding portion from falling off in the length direction of the connecting portion and preventing the holding portion from being lost.

[0085] In addition, the ball tube clamp has two through holes, and the connecting portion passes through the two through holes at the same time, so that the ball tube can be locked or released from two directions.

[0086] The embodiment of the present application also provides a ball tube assembly, which includes a ball tube and the ball tube locking device in the aforementioned embodiment. Regarding the installation method and positional relationship of the ball tube and the ball tube locking device, reference can be made to the description of the aforementioned embodiment and will not be repeated here.

[0087] The present application also provides a medical device, which includes: a column; an X-ray source assembly, which is mounted on the column via a cantilever, including the tube assembly in the previous embodiment.
