Abstract
Description
Technical Field
[0001] This specification relates to the field of medical device technology, and in particular to a track assembly, a medical imaging system, and tooling. Background Technology
[0002] Suspended digital subtraction angiography (DSA) equipment is commonly used in interventional operating rooms and hybrid operating rooms. It is typically suspended from the operating room ceiling using a combination of a crane and a track (i.e., the rail for the crane's movement). The crane and track arrangement must also accommodate the mobility requirements of the DSA equipment. When longer track lengths are required, a method of splicing basic guide rails with extension rails is usually used. However, the section of track containing the crane will deform due to the crane's weight. When the crane moves to the junction between the basic and extension rails, a discontinuity inevitably occurs between the contact surfaces of the traveling rollers (i.e., the height difference between the contact surfaces of the basic guide rail and the traveling rollers and the contact surfaces of the extension rail and the traveling rollers). Combined with installation and manufacturing errors, this results in significant wear and noise from the crane as it passes through the junction of the basic and extension rails. Utility Model Content
[0003] The purpose of this invention is to provide a track assembly, a medical imaging system, and tooling to solve the problem of wear and noise caused by the discontinuity at the joint between the base guide rail and the extension guide rail in the prior art.
[0004] This specification provides a track assembly comprising: a track and a guide belt; the track includes a base track and an extension track; the guide belt includes a base guide belt and an extension guide belt; the base track has a first guide wall; the base guide belt is disposed along the length direction of the base track and is at least partially laid on the first guide wall of the base track; the extension track is spliced to at least one end of the base track, and the extension track has a second guide wall; the extension guide belt is disposed along the length direction of the extension track and is at least partially laid on the second guide wall of the extension track; a first connecting seam is provided between the base track and the extension track, and a second connecting seam is provided between the base guide belt and the extension guide belt, the first connecting seam and the second connecting seam being staggered along the length direction of the base track.
[0005] In summary, in the track assembly, medical imaging system, and tooling provided by this utility model, by staggering the first connecting seam between the base track and the extended track (i.e., the junction of the base track and the extended track) and the second connecting seam between the base guide belt and the extended guide belt along the length direction of the base track, a guide belt without breaks is covered above the junction of adjacent base tracks and extended tracks. This reduces the impact of the discontinuity between the base track and the extended track on the rolling element (e.g., the traveling roller) when it passes through the junction of the base track and the extended track, thereby reducing the wear and noise of the traveling roller caused by the discontinuity between the base track and the extended track.

Detailed Implementation
[0016] To more clearly illustrate the technical solutions of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this specification. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.
[0017] As indicated in this specification and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not specifically singular and may include plural forms. Generally, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements. The term "based on" means "at least partially based on." The term "some embodiments" means "at least one embodiment"; the term "other embodiments" means "at least one additional embodiment," and the relevant definitions of other terms will be given in the description below.
[0018] Figure 1 These are schematic diagrams of the track assembly shown in some embodiments of this specification; Figure 2 This is a schematic diagram illustrating the interaction between the traveling rollers and the base track according to some embodiments of this specification. (In conjunction with...) Figure 1 and Figure 2As shown, in some embodiments, the track assembly 100 may include a track 110 and a guide belt 120 adapted to the track 110. The guide belt 120 may be configured to separate the rolling element (e.g., the traveling roller 211 hereinafter) from the track 110, thereby preventing the rolling element from directly contacting the track 110 during its travel along the track 110, reducing frictional losses between the rolling element and the track 110, and reducing resistance during the travel of the rolling element.
[0019] Track 110 may include a base track 111 and an extension track 112. The base track 111 has a first guide wall 1111, and the extension track 112 has a second guide wall 1121. The extension track 112 may be spliced to at least one end of the base track 111 to extend the overall length of the track 112. Guide belt 120 includes a base guide belt 121 and an extension guide belt 122. The base guide belt 121 is disposed along the length direction of the base track 111 and is at least partially laid on the first guide wall 1111 of the base track 111. The extension guide belt 122 is disposed along the length direction of the extension track 112 and is at least partially laid on the second guide wall 1121 of the extension track 112. When the extended track 112 abuts against the base track 111, there is a first connecting seam 113 between the base track 111 and the extended track 112, and there is a second connecting seam 123 between the base guide strip 121 on the base track 111 and the extended guide strip 122 on the abutting extended track 112. The first connecting seam 113 and the second connecting seam 123 are staggered along the length direction of the base track 111.
[0020] The length direction of the basic track 111 is the direction of its extension, which can be achieved through... Figure 1 The arrow X is used to indicate this. The first connecting seam 113 is the gap at the junction of the base track 111 and the extension track 112. The second connecting seam 123 is the gap at the junction of the base guide strip 121 and the extension guide strip 122. The staggered arrangement of the first connecting seam 113 and the second connecting seam 123 along the length direction of the base track 111 means that, in the length direction perpendicular to the base track 111, the projection areas of the first connecting seam 113 and the second connecting seam 123 do not overlap. In some embodiments, when the base track 111 abuts against the extension track 112, the base guide strip 121 on the base track 111 may abut against the extension guide strip 122 on the extension track 112. In some embodiments, when the base track 111 abuts against the extension track 112, the base guide strip 121 on the base track 111 may be spaced a certain distance from the extension guide strip 122 on the extension track 112.
[0021] By staggering the first connecting seam 113 and the second connecting seam 123 along the length of the base track 111, a complete guide belt 120 can be laid above the junction of the base guide belt 121 and the extended guide belt 122, such as the base guide belt 121 or the extended guide belt 122 laid above the junction of the base track 111 and the extended track 112. The complete guide belt 120 can reduce the impact of the discontinuity experienced by the rolling element when passing through the junction of the base track 111 and the extended track 112 (i.e., the first connecting seam 113), thereby reducing the wear and noise of the rolling element caused by the discontinuity between the base track 111 and the extended track 112.
[0022] Combination Figures 1-2 As shown, in some embodiments, the shape of the first guide wall 1111 in its cross-section perpendicular to the length direction of the base track 111 may include regular or irregular shapes such as rectangles and trapezoids. In some embodiments, the base guide strip 121 may be installed on one end face of the first guide wall 1111; by way of example only, the base guide strip 121 may be installed on the upper end face of the first guide wall 1111. In this example, the upper end face of the first guide wall 1111 refers to the end face on the upper side of the first guide wall 1111 in the height direction of the track 110. The height direction of the track 110 can be... Figure 2 The arrow Y in the diagram represents this. The first guide wall 1111 facilitates the installation of the base guide belt 121 onto the base track 111, allowing the traveling roller 211 to engage with the base track 111. In some embodiments, the upper surface of the first guide wall 1111 is parallel to the horizontal plane, ensuring that the base guide belt 121 remains parallel to the horizontal plane after installation on the base track 111, thus facilitating stable operation of the traveling roller 211. In some embodiments, the base track 111 may further include a first mounting wall 1113, which is connected to the side of the first guide wall 1111. The first mounting wall 1113 can be used to connect with the second mounting wall described below (exemplary connection methods may include magnetic connection, snap-fit connection, welding, etc.), thereby improving the connection strength between the base track 111 and the extension track 112.
[0023] Similarly, in some embodiments, the second guide wall (e.g., Figure 6 and Figure 8 The second guide wall 1121 may be plate-shaped, and the extended guide strip 122 is mounted on one end face of the second guide wall (by way of example only, the extended guide strip 122 is mounted on the upper end face of the second guide wall). The extended track 112 may also include a second mounting wall (e.g., Figure 6 and Figure 8The second mounting wall 1122 is perpendicular to the length direction of the extended track 112 and the plane on which the extended guide strip 122 is laid. In some embodiments, the second mounting wall may be connected to the tooling 300 described below for mounting the track assembly 100.
[0024] In some embodiments, the track 110 may include an aluminum guide rail, and the guide strip 120 may include a steel guide strip. In some embodiments, the track 110 may be formed using an aluminum extrusion process, which is convenient to process and has low cost.
[0025] In some embodiments, a lubricating layer may be provided on the plane of the guide belt 120 on which the rolling element (e.g., the traveling roller 211 hereinafter) rolls, to further reduce rolling friction between the rolling element and the guide belt 120. For example, the lubricating layer may be formed by applying a bio-lubricating grease to the outer peripheral surface of the rolling element and / or the plane of the guide belt 120. In some embodiments, a lubricating layer may be applied to the outer periphery of the rolling element to reduce rolling friction between the rolling element and the guide belt 120.
[0026] In some embodiments, the base track 111 and the extension track 112 can be joined together using a splicing component (not shown in the figure), such as a magnetic component, a snap-fit component, a screw, etc. In some embodiments, the base track 111 and the extension track 112 can be directly joined together, for example, by welding, bonding, or other methods.
[0027] In some embodiments, the guide strip 120 may further include a connecting guide strip 124, which may be disposed on the second guide wall of the extended track 112 (e.g., Figure 6 and Figure 8 The extended guide belt 122 is placed on the second guide wall 1121 and abuts against the end of the extended guide belt 122 that is away from the base guide belt 121. Since a second connecting seam 123 is formed between the extended guide belt 122 and the base guide belt 121, when installing the track assembly 100, it is necessary to push the extended guide belt 122 towards the base guide belt 121 to fill the second connecting seam 123, so as to avoid the extended guide belt 122 and the base guide belt 121 not abutting tightly, resulting in the second connecting seam 123 being too large and affecting the movement of the rolling element. By setting the connecting guide belt 124, it is easier for the operator to push the extended guide belt 122 towards the base guide belt 121 after the base track 111 and the extended track 112 abut, so that the extended guide belt 122 abuts against the base guide belt 121. On the other hand, it can fill the space between the end of the extended guide belt 122 away from the base guide belt 121 and the end of the extended track 112 away from the base track 111.
[0028] In some embodiments, the method of laying the guide strip 120 on the guide wall (including the first guide wall 1111 and / or the second guide wall 1121) may include bonding, magnetic connection, snap-fit connection, riveting, snap-fit connection, etc. As an example only, taking the laying of the base guide strip 121 on the first guide wall 1111 as an example, the base track 111 may have a first mounting groove 1112. Specifically, the first mounting groove 1112 is disposed on the first guide wall 1111, and the first mounting groove 1112 extends along the length direction of the base track 111 in a through-groove shape. The base guide strip 121 is inserted into the first mounting groove 1112 along the length direction of the base track 111, so that the first mounting groove 1112 engages and fixes the base guide strip 121. Similarly, the laying methods of extending the guide strip 122 and connecting the guide strip 124 can be the same as or similar to the laying method of the base guide strip 121, and will not be described in detail here.
[0029] In some embodiments, one end of the base track 111 is connected to an extension track 112 along its length. In some embodiments, the projection area of the second connecting seam 123 may be located on the projection area of the base track 111 along the length direction perpendicular to the base track 111. As an example only, the first end of the base track 111 is connected to the extension track 112, and the first end of the base guide belt 121 is shorter than the first end of the base track 111, meaning the first end of the base guide belt 121 is laid on the first guide wall 1111 of the base track 111. Therefore, the end of the extension guide belt 122 that connects to the base guide belt 121 needs to be laid on the base track 111. Thus, in the length direction perpendicular to the base track 111, the projection area of the second connecting seam 123 between the base guide belt 121 and the extension guide belt 122 is located on the projection area of the base track 111, allowing the first connecting seam 113 and the second connecting seam 123 to be staggered along the length direction of the base track 111.
[0030] In some embodiments, the projection area of the second connecting seam 123 may be located on the projection area of the extension track 112 in the direction perpendicular to the length of the base track 111. As an example only, the first end of the base track 111 is connected to the extension track 112, and the first end of the base guide strip 121 extends from the first end of the base track 111, i.e., the first end of the base guide strip 121 is laid on the second guide wall 1121 of the extension track 112. Therefore, in the direction perpendicular to the length of the base track 111, the projection area of the second connecting seam 123 between the base guide strip 121 and the extension guide strip 122 is located on the projection area of the extension track 112, and the first connecting seam 113 and the second connecting seam 123 may be staggered along the length of the base track 111.
[0031] In some embodiments, both ends of the base track 111 are connected to extension tracks 112 along its length. In some embodiments, the projection areas of the second connecting seams 123 at both ends of the base guide strip 121 can be located on the projection area of the base track 111 along the length direction perpendicular to the base track 111. As an example only, both the first and second ends of the base track 111 are connected to extension tracks 112, and the first and second ends of the base guide strip 121 are shorter than the first and second ends of the base track 111 (the length of the base guide strip 121 is less than the length of the base track 111), that is, the first and second ends of the base guide strip 121 are both laid on the first guide wall 1111 of the base track 111. Therefore, in the length direction perpendicular to the base track 111, the projection areas of the second connecting seams 123 between both ends of the base guide strip 121 and the extension guide strip 122 are all located on the projection area of the base track 111, and the first connecting seam 113 and the two second connecting seams 123 can be staggered along the length direction of the base track 111.
[0032] In some embodiments, the second connecting seams 123 at both ends of the base guide band 121 are located on different extended tracks 112. As an example only, both the first and second ends of the base track 111 are connected to extended tracks 112, and the first and second ends of the base guide band 121 extend from the first and second ends of the base track 111 respectively (the length of the base guide band 121 is greater than the length of the base track 111), that is, the first and second ends of the base guide band 121 are respectively laid on the second guide walls 1121 of the two extended tracks 112. Therefore, in the direction perpendicular to the length of the base track 111, the projection areas of the second connecting seams 123 between the two ends of the base guide band 121 and the extended guide band 122 are located on the projection areas of different extended tracks 112, and the first connecting seam 113 and the two second connecting seams 123 can be staggered along the length direction of the base track 111.
[0033] In some embodiments, in the direction perpendicular to the length of the base track 111, the projection area of the second connecting seam 123 at one end of the base guide strip 121 can be located on the projection area of the extension track 112, and the projection area of the second connecting seam 123 at the other end of the base guide strip 121 can be located on the projection area of the base track 111. As an example only, both the first and second ends of the base track 111 are connected to the extension track 112. The first end of the base guide strip 121 extends from the first end of the base track 111, and the second end of the base guide strip 121 is shorter than the second end of the base track 111, that is, the first end of the base guide strip 121 is laid on the second guide wall of the extension track 112 (e.g., ...). Figure 6 and Figure 8On the second guide wall 1121 of the base track 111, the second end of the base guide strip 121 is laid on the first guide wall 1111 of the base track 111. When the first end and the second end of the base guide strip 121 are respectively connected to an extended guide strip 122, in the direction perpendicular to the length of the base track 111, the projection area of the second connecting seam 123 between the first end of the base guide strip 121 and the corresponding extended guide strip 122 is located on the projection area of the extended track 112, and the projection area of the second connecting seam 123 between the second end of the base guide strip 121 and the corresponding extended guide strip 122 is located on the projection area of the base track 111. The first connecting seam 113 and the two second connecting seams 123 can be staggered along the length of the base track 111.
[0034] Figure 3 These are schematic diagrams of the structure of a medical imaging system according to some embodiments of this specification; Figure 4 yes Figure 3 A top view. Combined with... Figures 3-4 As shown, this specification also provides a medical imaging system 200, which may include a crane 210, an imaging device 220 connected to the crane 210, and a track assembly 100 as described in other embodiments of this specification. The crane 210 is provided with traveling rollers 211, which are rotatably connected to a guide belt 120. The hardness of the outer circumferential surface of the traveling rollers 211 is the same as or approximately the same as the hardness of the guide belt 120. "Approximately the same" means that the ratio of the hardness of the outer circumferential surface of the traveling rollers 211 to the hardness of the guide belt 120 is close to 1; for example, the ratio is in the range of 0.9 to 1.1. By using traveling rollers 211 and guide belts 120 with the same or approximately the same material hardness, the frictional loss between the traveling rollers 211 and guide belts 120 during the movement of the overhead crane 210 along the track 110 can be greatly reduced, thus reducing the resistance of the imaging equipment 220 during its movement, minimizing debris generation, and ensuring the cleanliness of the operating room. Furthermore, because the materials have the same or approximately the same hardness, the guide belt 120 experiences less deformation during the movement of the traveling rollers 211. When the traveling rollers 211 pass through the junction of the base track 111 and the extension track 112, the impact of the step difference on the traveling rollers 211 is less, further reducing wear and noise on the traveling rollers 211.
[0035] In some embodiments, the imaging device 220 may include a C-arm 221, a radiation source 222, and a detector 223. The C-arm 221 has two opposing ends. The radiation source 222 is mounted on one end of the C-arm 221, and the detector 223 is mounted on the other end of the C-arm 221, with the radiation source 222 and detector 223 aligned. The radiation source 222 is a device capable of emitting X-rays, gamma rays, or electron beams. The detector 223 is a device capable of receiving the radiation emitted by the radiation source 222. The cooperation of the radiation source 222 and the detector 223 enables medical examinations or treatments. In some embodiments, the detector 223 may be a flat panel detector 223. The radiation emitted by the radiation source 222 passes through the patient and is received by the detector 223 for imaging processing. The imaging device 220 is a digital subtraction angiography imaging device, which can be used in the fields of angiography, cardiology, and neurology.
[0036] In some embodiments, the medical imaging system 200 may further include a suspended walking device, which includes a crane 210 and a track assembly 100 as described in other embodiments of this specification. The track assembly 100 is fixed at a predetermined position, such as on the ceiling of an operating room. The track assembly 100 may include at least two rows of tracks 110 (e.g., a first track 110-1 and a second track 110-2) arranged side by side along the width direction of the crane 210. The crane 210 has a plate-like or plate-like structure (e.g., replacing the sharp corners of the plate-like structure with rounded corners). The two sides of the crane 210 in the width direction cooperate with the two rows of first tracks 110-1 and second tracks 110-2 arranged side by side, so that the crane 210 can move along the length direction of the track 110. The imaging device 220 is mounted on the crane 210, so that the crane 210 drives the imaging device 220 to move, giving the imaging device 220 a higher degree of flexibility and freedom. In this case, the width direction of the overhead crane 210 is perpendicular to the length direction of the track 110 (e.g., Figure 3 The direction indicated by the arrow X in the image) and the height direction of track 110 (e.g., Figure 3 (The direction indicated by the arrow Y in the image) can be reached through... Figure 4 The arrow Z in the diagram represents this.
[0037] In some embodiments, the overhead crane 210 has mounting holes (not shown). The medical imaging system 200 also includes a mounting module 230 connected to the C-arm 221 of the imaging device 220. The mounting module 230 connects to the mounting holes on the overhead crane 210 to connect the overhead crane 210 to the imaging device 220. The overhead crane 210, in conjunction with the first track 110-1 and the second track 110-2, can improve the stability of the overhead crane 210 driving the imaging device 220 during operation.
[0038] In some embodiments, the overhead crane 210 may have multiple support seats 212 distributed around the crane 210, and traveling rollers 211 may be mounted on the support seats 212 via bearing seats 213. At least two traveling rollers 211 may be provided on each support seat 212 along the extension direction of the track 110. In some embodiments, the support seat 212 may also have only one traveling roller 211. The presence of traveling rollers 211 around the crane 210 via the support seats 212 ensures balanced support for the crane 210 and avoids affecting the operation of the imaging device 220. In some embodiments, having at least two traveling rollers 211 at each point around the crane 210 reduces the bearing stress on a single traveling roller 211, reduces the pressure on the traveling roller 211, and thus reduces wear on the traveling roller 211.
[0039] Combination Figures 2-4 As shown, in some embodiments, the overhead crane 210 may further include auxiliary traveling rollers 214. The auxiliary traveling rollers 214 are mounted on the support base 212, and their axial direction is parallel to that of the traveling rollers 211. The auxiliary traveling rollers 214 engage with the other end face of the guide wall and can roll along the other end face of the first guide wall 1111. As an example only, when the auxiliary traveling rollers 214 are running on the base track 111, they engage with the lower end face of the first guide wall 1111. That is, the traveling rollers 211 and auxiliary traveling rollers 214 are correspondingly arranged along the height direction of the overhead crane 210 (the height direction of the overhead crane 210 can be parallel to the height direction of the track 110), meaning that one or more auxiliary traveling rollers 214 are correspondingly arranged below each traveling roller 211.
[0040] In some embodiments, the traveling roller 211 and the auxiliary traveling roller 214 may abut against two opposite end faces of the guide wall, respectively. For example, when the crane 210 is running on the base track 111, the traveling roller 211 abuts against the upper end face of the first guide wall 1111, and the auxiliary traveling roller 214 abuts against the lower end face of the first guide wall 1111. In some embodiments, one of the traveling roller 211 and the auxiliary traveling roller 214 abuts against two opposite end faces of the guide wall. For example, when the crane 210 is running on the base track 111, the traveling roller 211 abuts against the upper end face of the first guide wall 1111, while the auxiliary traveling roller 214 is spaced apart from the lower end face of the first guide wall 1111 by a preset distance (e.g., the preset distance can be 1mm, 3mm, 5mm, etc.). When the crane 210 is running smoothly, the absence of contact between the auxiliary traveling roller 214 and the lower end face of the first guide wall 1111 can reduce the friction between the crane 210 and the track 110. When the crane 210 sways, the traveling roller 211 may detach from the upper surface of the first guide wall 1111. At this time, the auxiliary traveling roller 214 can abut against the lower surface of the first guide wall 1111 to prevent the crane 210 from derailing from the track 110. By applying constraint to the other end surface (lower end surface) of the first guide wall 1111 by the auxiliary traveling roller 214, it is possible to prevent the crane 210 from tilting and affecting the normal operation of the imaging device 220 if the center of gravity of the imaging device 220 is not below the center of gravity of the crane 210. In addition, the arrangement of an auxiliary traveling roller 214 below each traveling roller 211 ensures that the crane 210 is subjected to more balanced forces.
[0041] Figure 5 These are schematic diagrams of the tooling structure shown in some embodiments of this specification; Figure 6 This is a schematic diagram illustrating the connection between the tooling and the track assembly according to some embodiments of this specification; Figure 7 yes Figure 6 The left view; Figure 8 yes Figure 7 A cross-sectional view along the AA direction. (Combined with...) Figures 5-8As shown in the diagram, this specification also provides a tooling 300 for installing the track assembly 100. The tooling 300 may include a fixing part 310, an abutting part 320, and a driving part 330. Both the abutting part 320 and the driving part 330 are connected to the fixing part 310, which is fixedly connected to the extension track 112 of the track assembly 100. Under the action of the driving part 330, the abutting part 320 pushes the extension guide belt 122 to abut against the base guide belt 121. The connection and fixation between the fixing part 310 and the extension track 112 of the track assembly 100 means that the relative positions of the fixing part 310 and the extension track 112 are fixed during the installation of the track assembly 100. It should be noted that during the laying of the guide belt 120, the extended guide belt 122 and the base guide belt 121 will form a second connecting seam 123. In order to avoid the gap at the joint between the extended guide belt 122 and the base guide belt 121 being too large and causing the rolling element (e.g., the traveling roller 211) to be obstructed when passing through the second connecting seam 123, the extended guide belt 122 needs to be pushed to the side of the base guide belt 121 before the rolling element is placed in order to fill the second connecting seam 123. This process is the installation of the track assembly 100.
[0042] In some embodiments, the fixing part 310 may include a fixing base 311 and a connecting plate 313 mounted on the fixing base 311. The abutment part 320 and the driving part 330 are also mounted on the fixing base 311. The connecting plate 313 is fixedly connected to the extension rail 112 of the rail assembly 100, thereby connecting the fixing part 310 to the extension rail 112 so that the rail assembly 100 can be installed through the cooperation of the abutment part 320 and the driving part 330 provided on the fixing part 310. As an example only, the extension rail 112 may include a second mounting wall 1122 connected to the second guide wall 1121. The connecting plate 313 and the second mounting wall 1122 of the extension rail 112 can be connected by connectors (e.g., magnetic assemblies, bolt and nut assemblies, snap-fit and slot assemblies, rivets, etc.), or the connecting plate 313 and the sidewall of the extension rail 112 can be directly connected by welding, bonding, etc. For example, in Figure 6 and Figure 8 In the embodiment shown, the connecting plate 313 and the second mounting wall 1122 of the extension track 112 can be fixedly connected by bolts.
[0043] In some embodiments, when the guide belt 120 includes a connecting guide belt 124, the abutment portion 320 can push the connecting guide belt 124 to move under the action of the drive portion 330, thereby pushing the extended guide belt 122 to abut against the base guide belt 121 to fill the second connecting seam 123 between the extended guide belt 122 and the base guide belt 121.
[0044] In some embodiments, when the guide belt 120 includes only the extended guide belt 122 and the basic guide belt 121, the abutment portion 320 can push the extended guide belt 122 to abut against the basic guide belt 121 under the action of the drive portion 330, so as to fill the second connecting seam 123 between the extended guide belt 122 and the basic guide belt 121.
[0045] In some embodiments, the drive unit 330 may include a screw that is movable along the length direction of the base track 111, i.e., along the length direction of the track 110. The abutment unit 320 may include an abutment block that, under the push of the screw, pushes the guide strip 120 to abut against the base guide strip 121. By way of example only, in some embodiments, the fixing base 311 has a stepped hole 312, which includes a first hole segment 3121 and a second hole segment 3122 coaxially arranged, the diameter of the first hole segment 3121 being smaller than the diameter of the second hole segment 3122. When the fixing unit 310 is connected to the track 110, the axis of the stepped hole 312 is parallel to the length direction of the track 110, and the second hole segment 3122 is located on the side of the first hole segment 3121 closer to the guide strip 120. One end of the screw is located within the first hole section 3121 and connects to the abutment block housed within the second hole section 3122. The other end of the screw is located on the side of the first hole section 3121 away from the second hole section 3122. The diameters of both ends of the screw are larger than the diameter of the hole in the first hole section 3121. As the screw moves toward the guide band 120, it can push the abutment block toward the guide band 120, thereby pushing the extended guide band 122 to abut against the base guide band 121, filling the second connecting seam 123. Furthermore, since the diameters of both ends of the screw are larger than the diameter of the hole in the first hole section 3121, the screw will not detach from the first hole section 3121 during movement. The first hole section 3121 can ensure stable movement of the screw while also guiding and positioning its movement.
[0046] In some embodiments, the abutment block has an abutment groove 321 adapted to the end of the guide strip 120. The abutment groove 321, when pushed by a screw, pushes the guide strip 120 to abut against the base guide strip 121. By providing the abutment groove 321 on the abutment block, the contact area between the abutment block and the guide strip 120 can be increased, thereby improving the stability of the guide strip during movement. This is merely an example. Figure 8 In the illustrated embodiment, the guide belt 120 includes a connecting guide belt 124 located at the end of the extended guide belt 122 away from the base guide belt 121. One end of the connecting guide belt 124 is laid on the extended track 112, and the other end extends out of the extended track 112. As the abutment block moves toward the connecting guide belt 124 under the push of the screw, the end of the connecting guide belt 124 extending out of the extended track 112 can be inserted into the abutment groove 321 and engage with it, and follow the movement of the abutment block to push the extended guide belt 122 to abut against the base guide belt 121.
[0047] In some embodiments, the abutment block has an abutment protrusion (not shown in the figure), which, under the push of the screw, pushes the guide belt 120 to abut against the base guide belt 121. By providing the abutment protrusion on the abutment block, the guide belt 120 can be moved even when it does not extend beyond the extension track 112. By way of example only, the guide belt 120 includes only the base guide belt 121 and the extension guide belt 122. The end of the extension guide belt 122 away from the base guide belt 121 is laid on the extension track 112, and the abutment block cannot directly contact the extension guide belt 122 to push it to move. By providing the abutment protrusion, the abutment protrusion can contact the extension guide belt 122, thereby pushing the extension guide belt 122 toward the base guide belt 121.
[0048] In some embodiments, the tooling 300 may further include a resilient reset member configured to provide an elastic force to the abutment 320 such that when the external force applied to the abutment 320 by the drive portion 330 weakens or disappears, the abutment 320 can move away from the guide band 120, making it easier for the operator to remove the tooling 300 from the track assembly 100. By way of example only, the resilient reset member may include a spring, one end of which is connected to the abutment block and the other end to a screw. When installing the track assembly 100, an external force can be applied to the screw, for example, by the operator manually pressing the screw and moving it toward the guide band 120. The screw will push the spring and the abutment block toward the guide band 120, thereby pushing the extended guide band 122 toward the base guide band 121, during which the spring is compressed and deformed. Once the second joint 123 between the extended guide band 122 and the base guide band 121 is filled, the operator can remove the external force applied to the screw, at which point both the screw and the abutment block will move away from the guide band 120 under the elastic force of the resilient reset member.
[0049] In some embodiments, the tooling 300 may further include a limiting portion 340, which may be connected to the fixing portion 310. The limiting portion 340 may be configured to limit the movement range of the abutment portion 320. On the one hand, this can prevent the abutment portion 320 from moving excessively, causing excessive compression and damage to the basic guide belt 121 and the extended guide belt 122. On the other hand, it can prevent the abutment portion 320 from moving excessively toward the guide belt 120, thereby detaching from the fixing portion 310. As an example only, the limiting portion 340 may include a limiting plate connected to the connecting plate 313. In the longitudinal direction of the track, the projection of the abutment block at least partially coincides with the projection of the limiting plate, so that when the abutment block is pushed by the screw toward the guide belt to a certain position, it will abut against the limiting plate, preventing the abutment block from excessively pushing the connecting guide belt 124, thereby causing the extended guide belt 122 and the basic guide belt 121 to be squeezed and deformed. In addition, by limiting the movement stroke of the abutment block by the limiting plate, it can also prevent the abutment block from falling out of the stepped hole 312.
[0050] In some embodiments, when the track assembly 100 includes two parallel tracks 110, such as Figure 3 When the first track 110-1 and the second track 110-2 are installed, the first track 110-1 and the second track 110-2 can be installed using the same two tooling 300s, or the first track 110-1 and the second track 110-2 can be installed sequentially using the same tooling 300. That is, the tooling 300 can be used to install the first track 110-1 or the second track 110-2. The fixing part (310) can be installed on one of the tracks (such as the first track 110-1) or on the other track (such as the second track 110-2). The abutting part 320 may include a first abutting part 320-1 and a second abutting part 320-2, and the driving part 330 includes a first driving part 330-1 and a second driving part 330-2. When the fixing part (310) is installed on one of the tracks (such as the first track 110-1), the first abutting part 320-1, under the action of the first driving part 330-1, pushes the extended guide belt 122 in one track 110 to abut against the basic guide belt 121. When the fixing part 310 is installed on another track (such as the second track 110-2), the second abutting part 320-2, under the action of the second driving part 330-2, pushes the extended guide belt 122 in the other track 110 to abut against the basic guide belt 121.
[0051] For ease of description, we can... Figure 8 Along the height direction of the track 110, the stepped hole 312 located at the top of the fixed base 311 is designated as the first stepped hole 312-1, and the stepped hole 312 located at the bottom of the fixed base 311 is designated as the second stepped hole 312-2. The screw located in the first stepped hole 312-1 (e.g., the first hole segment 3121 of the first stepped hole 312-1) is designated as the first screw (i.e., the first drive part 330-1), and the screw located in the second stepped hole 312-2 (e.g., the first hole segment 3121 of the second stepped hole 312-2) is designated as the second screw (i.e., the second drive part 330-2). The abutment block disposed in the first stepped hole 312-1 (e.g., the second hole segment 3122 of the first stepped hole 312-1) is designated as the first abutment block (i.e., the first abutment portion 320-1), and the abutment block disposed in the second stepped hole 312-2 (e.g., the second hole segment 3122 of the second stepped hole 312-2) is designated as the second abutment block (i.e., the second abutment portion 320-2). In some embodiments, the tooling 300 can be a symmetrical structure. For example, the first stepped hole 312-1 and the second stepped hole 312-2, the first abutment portion 320-1 and the second abutment portion 320-2, the first driving portion 330-1 and the second driving portion 330-2 can be symmetrical along the same plane, which can be symmetrical through... Figure 6The plane O is represented by the number O in the diagram. It is perpendicular to the height direction of the track and parallel to the length direction of the track.
[0052] As an example only, in Figure 8 In the embodiment shown, when tooling 300 is used for installation Figure 3 When the second track 110-2 is shown, the fixing part 310 is connected to the second track 110-2 via the connecting plate 313. The second screw and the second abutment block are located at the bottom of the fixing base 311, and the second guide wall 1121 is also located at the bottom of the extension track 112 of the second track 110. The positions of the second screw and the second abutment block correspond to those of the second guide wall 1121. The second abutment block of the fixing part 310 can be pushed by the second screw to abut against the extension guide strip 122 located in the track 110 and the base guide strip 121.
[0053] In another example, when tooling 300 is installed Figure 3 When the first orbital 110-1 is shown, due to the symmetrical relationship between the first orbital 110 and the second orbital 110, it is possible to utilize... Figures 6-8 The tooling 300 shown is used to install the first track 110-1. For example, when the tooling 300 is applied to install the first track 110-1, the first screw and the first abutment block correspond to the second guide wall 1121 of the extension track 112 of the first track 110, so the first abutment block of the fixing part 310 can be pushed by the first screw to abut the extension guide strip 122 located in the first track 110 against the base guide strip 121. The tooling 300 configured in this way can be reused, reducing manufacturing costs and simplifying the installation steps.
[0054] The beneficial effects of the track assembly, medical imaging system, and tooling provided in this specification include, but are not limited to: (1) by staggering the first connecting seam between the base track and the extended track (i.e., the junction of the base track and the extended track) and the second connecting seam between the base guide belt and the extended guide belt along the length direction of the base track, so that the junction of adjacent base tracks and extended tracks is covered with an unbroken guide belt, the impact of the discontinuity between the base track and the extended track on the rolling element (e.g., the traveling roller) when passing through the junction of the base track and the extended track is reduced, thereby reducing the wear and noise of the traveling roller caused by the discontinuity between the base track and the extended track; (2) a lubricating layer can be provided on the plane of the guide belt for the rolling element to roll, so as to further reduce the rolling friction between the rolling element and the guide belt. For example, the lubricating layer can be formed by applying biological grease to the outer peripheral surface of the rolling element and / or the plane of the guide belt. In some embodiments, a lubricating layer can be coated on the outer periphery of the rolling element to reduce the rolling friction between the rolling element and the guide belt; (3) By setting a connecting guide belt, on the one hand, it is convenient for the operator to push the extended guide belt to the side of the base guide belt, and on the other hand, it can fill the space between the end of the extended guide belt 122 away from the base guide belt and the end of the extended track away from the base track; (4) By designing a tooling with a symmetrical structure, the tooling can be reused when installing two symmetrical tracks, reducing manufacturing costs while simplifying the installation steps.
