Referring to fig. 3 to 6, when detaching the body coil, the body 110 may be firstly passed through the body coil 400, and the body 110 is supported on the bracket assembly 200, then the supporting portion 120 is supported on the inner surface of the body coil 400, then the fastening member of the body coil 400 is removed, so that the body coil 400 is loosened from the magnetic resonance imaging apparatus, and due to the supporting function of the supporting portion 120, the position of the loosened body coil 400 relative to the magnetic resonance imaging apparatus is substantially maintained unchanged, then the body coil may be pushed or the supporting portion 120 may be moved, so that the body coil 400 and the supporting portion 120 move together along the first direction, so as to move the body coil 400 out of the magnetic resonance imaging apparatus. In addition, due to the fact that the dismounting and mounting are rapid, the time of an operator exposed in a magnetic field can be reduced, and the safety of the dismounting and mounting process is improved. Compare in the dismantlement mode among the correlation technique, the body coil assembly and disassembly tools independence and the commonality that this embodiment provided are high, need not to set up special support mounting and set up strip guide rail on gradient coil on body coil to body coil and gradient coil's structure has been simplified.

Fig. 7 is a partially enlarged schematic view of fig. 2. Referring to fig. 7, in some embodiments, each of the at least one supporting portion 120 includes: at least one supporting bar 121, a first end of each supporting bar 121 being connected to the body 110, and a second end of each supporting bar 121 being adapted to contact an inner surface of the body coil 120. By supporting the coil 120 using the support rod 121, the structure of the support portion 120 can be simplified and the manufacturing process can be facilitated.

It can be understood that, if each support portion 120 includes only one support rod 121, the body coil 400 can be movably supported at the second end of the support rod 121, that is, there is a support point between the body coil 400 and each support portion 120, the body coil 400 is movably connected to the support rod 121, and the body coil 400 can shake relative to the support rod 121 under the action of external force. When each of the support parts 120 includes a plurality of support bars 121, the second ends of the plurality of support bars 121 may be spaced apart in the circumferential direction of the body coil 120, thereby fixedly supporting the body coil 400 on the support parts 120. In addition, when the body coil 400 is movably connected to the supporting rod 121, the body coil 400 may be moved out of the magnetic resonance imaging apparatus by pushing the supporting rod 121, and when the body coil 400 is fixedly connected to the supporting rod 121, the body coil 400 may be moved out of the magnetic resonance imaging apparatus by directly pushing the body coil 400.

Alternatively, each of the support parts 120 may include three support bars 121, and the three support bars 121 may be disposed at equal intervals in the circumferential direction of the body coil 400, so that each of the support parts 120 and the inner surface of the body coil 400 may have three support points, so that the support stability of the support part 120 is higher.

Further alternatively, the second end of each of the at least one support bar 121 may be provided with a slip prevention part 125 for increasing a frictional force with the inner surface of the body coil 400. The structure of the anti-slip part 125 may be various, for example, the anti-slip part 125 may be made of anti-slip material such as rubber. Alternatively, the surface of the slip prevention part 125 may be provided with a texture to increase friction with the body coil 400.

In some embodiments, the first end of each of the at least one supporting bar 121 is hinged to the body 110, and each of the at least one supporting bar 121 is at a first angle with respect to the body 110, and the first angle is adjustable. That is, the first angle between each supporting rod 121 and the body 110 can be adjusted as required, and the supporting rods 121 can also be fixed at the adjusted first angle.

It can be understood that, in each support portion 120, the second ends of the plurality of support bars 121 can be connected into a circle, and the diameter size of the circle can be adjusted accordingly by adjusting the first angle between the support bars 121 and the body 110, so that the support portion 120 can be adapted to body coils 400 with different sizes, and the versatility of the body coil assembly and disassembly tools is improved.

Fig. 8 is a schematic structural view of the moving assembly in fig. 1 in a storage state. Referring to fig. 7 and 8, the body coil assembling and disassembling tool may have a storage state and an operating state, when in the operating state, the second end of the supporting rod 121 may be supported on the inner surface of the body coil 400, and the body coil assembling and disassembling tool may be used to assemble and disassemble the body coil. When the body coil disassembling tool is in the storage state, the first angle between the supporting rod 121 and the body 110 can be adjusted, so that the supporting rod 121 can be attached to the body 110 as much as possible, and the volume of the body coil disassembling tool after storage is reduced.

With continued reference to fig. 7, in some embodiments, each support 120 of the at least one support 120 further includes an adjustment member 600 for adjusting the first angle, the adjustment member 600 being disposed on the body 110, the adjustment member 600 including: a sliding sleeve 123, a locking member 122, and at least one sub-connecting rod 124.

The sliding sleeve 123 is sleeved on the body 110, and the sliding sleeve 123 may be a cylindrical structure and can freely slide on the body 110.

The sub-connection rods 124 have a rod-shaped structure, and a first end of each sub-connection rod 124 is hinged to the sliding sleeve 123 and a second end thereof is hinged to one of the support rods 121. Alternatively, the sub-connecting rod 124 is hinged at a first end thereof to the outer surface of the sliding sleeve 123 and at a second end thereof to a middle position of the supporting rod 121.

The locking member 122 is used to lock the distance between the sliding sleeve 123 and the first end of the supporting rod 121. It can be understood that the sliding sleeve 123 can be located between the first end of the supporting rod 121 and the locking member 122, the sliding sleeve 123 can abut against the locking member 122, and the distance between the sliding sleeve 123 and the first end of the supporting rod 121 can be adjusted by adjusting the position where the locking member 122 is connected to the body 110, so as to adjust the first angle between the supporting rod 121 and the body 110 and fix the supporting rod 121 at the first angle. Moreover, the first angles between the plurality of support bars 121 and the body 110 can be adjusted simultaneously by adjusting the locking member 122, so that the adjustment is more convenient.

In some embodiments, the locking member 122 may have an internal thread, the body 110 may have an external thread, the locking member 122 is screwed to the body 110, and by rotating the locking member 122, a first angle between the supporting rod 121 and the body 110 may be adjusted, and the supporting rod 121 may be fixedly connected to the first angle, which is simple in structure and easy to implement.

In the above embodiments, the first angle between the supporting rod 121 and the body 110 is adjustable. In other embodiments, the first end of each of the at least one supporting bar 121 is fixedly connected to the body 110, and each of the at least one supporting bars 121 forms a second angle with the body 110. The second angle between each support bar 121 and the body 110 is a fixed angle and is not adjustable, and the structure can also realize a supporting function for the body coil 400. Taking the example that each support part 120 includes a plurality of support bars 121, when the inner diameter of the body coil 400 to be disassembled is the same as the diameter of the circle in which the second ends of the plurality of support bars 121 are located, the second end of each support bar 121 may contact the inner surface of the body coil 400, so that the body coil 400 and the support part 120 may be kept relatively fixed. If the inner diameter of the body coil 400 is greater than the diameter of the circle, the second end of at least one of the plurality of support bars 121 may contact the inner surface of the body coil 400, so that the body coil 400 may be movably supported on the support part 120.

In some embodiments, the moving assembly 100 may include two supporting portions 120, and the two supporting portions 120 are oppositely disposed on the body 110 along the first direction. The two supporting parts 120 may be spaced apart in the first direction and may be symmetrically disposed about a plane perpendicular to the first direction, so that the coil 400 may be supported from both ends, respectively, with a better supporting effect.

Referring to fig. 2, as an optional implementation manner of the body 110, the body 110 may include: a first telescopic rod 111a, a second telescopic rod 111b and an intermediate rod 112, the intermediate rod 112 being connectable between the first telescopic rod 111a and the second telescopic rod 111 b. The first telescopic rod 111a and the second telescopic rod 111b extend along a first direction and can move in a telescopic manner along the first direction. Taking the dimension along the first direction as the length, the first telescopic rod 111a and the second telescopic rod 111b can change their respective lengths in a telescopic movement manner.

Alternatively, a support portion 120 may be disposed between the first telescopic rod 111a and the middle rod 112, and a support portion 120 may be disposed between the second telescopic rod 111b and the middle rod 112, so as to stabilize the supporter coil 400.

As shown in fig. 3, when the body coil needs to be disassembled, the body 110 may be firstly inserted through the body coil 400, the body 110 is supported on the support assembly 200, and then the support portion 120 is supported on the inner surface of the body coil 400, at this time, the states of the first telescopic rod 111a and the second telescopic rod 111b may be referred to fig. 1, that is, the first telescopic rod 111a may be in a contracted state with a short length, and the second telescopic rod 111b may be in an extended state with a long length, and then the fastener of the body coil 400 is removed, so that the body coil 400 is released from the magnetic resonance imaging apparatus, and due to the support effect of the support portion 120, the position of the released body coil 400 relative to the magnetic resonance imaging apparatus remains substantially unchanged, referring to fig. 4 to 6, the body coil 400 is pushed, the first telescopic rod 111a is extended, and at the same time, the second telescopic rod 111b is shortened, so that the body coil 400 together with the support portion 120 moves in the first direction until the body coil 400 is moved out of the magnetic resonance imaging apparatus.

Referring to fig. 8, when the first telescopic rod 111a and the second telescopic rod 111b are both in the retracted state, the moving assembly 100 can be in the storage state. Therefore, the first and second telescopic rods 111a and 111b can not only realize the movement of the body coil 400 along the first direction, but also reduce the storage size of the moving assembly 100, thereby facilitating storage and transportation.

Of course, in the embodiment shown in fig. 3 to 6, the length of the first telescopic rod 111a is increased and the length of the second telescopic rod 111b is decreased during the process of detaching the body coil 400, and in other embodiments, the positions of the first telescopic rod 111a and the second telescopic rod 111b may be reversed, that is, the length of the first telescopic rod 111a is decreased and the length of the second telescopic rod 111b is increased during the process of detaching the body coil 400, which is not particularly limited herein.

As an optional way for the first telescopic rod 111a and the second telescopic rod 111b to realize the telescopic movement, the first telescopic rod 111a and the second telescopic rod 111b respectively include: the plurality of first sub-rods 1111 are sequentially sleeved from outside to inside along the rod diameter direction, and each first sub-rod 1111 of the plurality of first sub-rods 1111 can move in a first direction relative to the adjacent first sub-rods 1111.

Alternatively, the outer surface of the first sub-rod 1111 located at the inner portion of the two adjacent first sub-rods 1111 may be provided with at least one first strip-shaped protrusion extending along the first direction, the inner surface of the first sub-rod 1111 located at the outer portion may be provided with at least one first strip-shaped groove extending along the first direction, and each first strip-shaped protrusion is engaged with each first strip-shaped groove one by one and can slide relative to each other, so that the relative movement of the two adjacent first sub-rods 1111 along the first direction is realized.

The intermediate rod 112 may also extend along the first direction, and the structure may be various, for example, the length of the intermediate rod 112 along the first direction may be constant, or alternatively, the intermediate rod 112 may be a telescopic rod, which can also move telescopically along the first direction, so as to change the length of the intermediate rod 112. By changing the length of the intermediate lever 112, the two support parts 120 at both ends of the intermediate lever 112 can be supported at positions close to both ends of the body coil 400, respectively, thereby improving the supporting effect of the body coil 400.

When the mobile assembly 100 needs to be stored, the middle rod 112 can be adjusted to be in a contraction state with a smaller length, the storage size of the mobile assembly 100 can be further reduced, and the storage and the transportation are convenient.

Referring to fig. 7, as an optional way for the middle rod 112 to achieve the telescopic movement, the middle rod 112 includes an outer rod 113 and two inner rod assemblies 114 disposed in the outer rod 113 and capable of extending from the outer rod 113 in opposite directions, each inner rod assembly 114 of the two inner rod assemblies 114 includes a plurality of second sub-rods 1141, the plurality of sub-rods 1141 may be sequentially sleeved from outside to inside along a radial direction of the outer rod 113, and each second sub-rod 1141 of the plurality of second sub-rods 1141 may move in a first direction relative to the adjacent second sub-rod 1141.

Optionally, the outer surface of the inner second sub-rod 1141 of the two adjacent second sub-rods 1141 may be provided with at least one second strip-shaped protrusion extending along the first direction, the inner surface of the outer second sub-rod 1141 may be provided with at least one second strip-shaped groove extending along the first direction, and each second strip-shaped protrusion may be matched with each second strip-shaped groove one by one and may slide relative to each other, so as to achieve the relative movement of the two adjacent second sub-rods 1141 along the first direction.
