Description

Technical Field

[0001] The present application relates to the field of magnetic resonance technology, and more specifically, to a magnetic resonance cavity bracket installation and adjustment mechanism and a magnetic resonance device. Background Art

[0002] In magnetic resonance equipment, a magnetic resonance bed generally needs to be used in conjunction with a magnetic resonance magnet, and the installation of the magnetic resonance bed generally needs to be achieved through an intracavity bracket installed in the cavity of the magnetic resonance magnet. When the intracavity bracket is placed in the cavity of the magnetic resonance magnet, the horizontality and vertical position of the intracavity bracket are very important, otherwise it will affect the operation and use of the magnetic resonance bed. In the prior art, the position of the intracavity bracket on the magnetic resonance magnet is usually fixed, so it is inconvenient to flexibly adjust the magnetic resonance bed to a better position for use. In addition, a driving wheel is usually required on the intracavity bracket, and a driving shaft is provided on the driving wheel to connect with the driving end of the driving device, so that the driving wheel can be driven to run by the driving device, so that the sliding seat connected to the driving wheel can move, so that when the magnetic resonance bed is arranged on the sliding seat, the magnetic resonance bed can be driven to move by the sliding seat. However, in the prior art, since the position of the driving wheel on the intracavitary stent is usually fixed and inconvenient to adjust flexibly, when installing the intracavitary stent, the installer must always pay attention to the horizontal and vertical positioning of the intracavitary stent, and at the same time ensure that the driving shaft on the driving wheel and the driving end of the driving device can be accurately connected in place. The whole operation is rather cumbersome, time-consuming and labor-intensive, resulting in low installation efficiency.

Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present application.

[0035] Embodiment 1: This embodiment of the present application provides a magnetic resonance cavity bracket installation and adjustment mechanism, such as Figures 1 to 5 As shown in , the magnetic resonance cavity bracket installation adjustment mechanism includes a first positioning adjustment component 1 and a second positioning adjustment component 2; Figures 6 to 9As shown in the figure, the first positioning and adjustment component 1 includes a fixing seat 11 for connecting to the magnetic resonance magnet 100, a supporting seat 12 arranged on the fixing seat 11 and capable of vertically moving up and down relative to the fixing seat 11, and a locking member 13 arranged on the supporting seat 12 and used for locking with the intracavitary support 200; the second positioning and adjustment component 2 includes a first mounting seat 21 for connecting to the intracavitary support 200, a first supporting frame 22 arranged on the first mounting seat 21 and capable of horizontally moving left and right relative to the first mounting seat 21, and a second supporting frame 23 arranged in the first supporting frame 22 and capable of vertically moving up and down relative to the first supporting frame 22; the second supporting frame 23 is used to install the driving wheel 10.

[0036] The application method of the magnetic resonance intracavitary support installation and adjustment mechanism of the embodiment of the present application is: a magnetic resonance magnet 100 and a driving device 300 are selected, and the driving device 300 is located on the front side of the magnetic resonance magnet 100. Then, four groups of first positioning adjustment components 1 are set, two of which are distributed at intervals on the front side of the magnetic resonance magnet 100, and the other two groups of first positioning adjustment components 1 are distributed at intervals on the rear side of the magnetic resonance magnet 100, and the first positioning adjustment components 1 on the front and rear sides correspond to each other. Specifically, each fixing seat 11 is fixedly connected to the outer wall of the magnetic resonance magnet 100, and the support seat 12 on each fixing seat 11 is opposite to the cavity of the magnetic resonance magnet 100, and then a horizontal ruler (not shown in the figure) is placed on the intracavity bracket 200 to be installed in the cavity of the magnetic resonance magnet 100, so that the intracavity bracket 200 is penetrated into the cavity of the magnetic resonance magnet 100 and placed on four support seats 12. In this process, the position of the intracavity bracket 200 can be flexibly adjusted, first the intracavity bracket 200 is located at the vertical center of the cavity of the magnetic resonance magnet 100, and then each locking member is connected to the bottom of the intracavity bracket 200, and then the support seat 12 can be adjusted to move up or down relative to the fixing seat 11 until the intracavity bracket 200 is judged to be level according to the measurement of the horizontal ruler (not shown in the figure). When the horizontal and vertical positions of the intracavity bracket 200 are adjusted in place, the orientation of the driving wheel 10 can be adjusted by the second positioning adjustment component 2. Specifically, the driving wheel 10 is first installed on the second support frame 23, and then the first mounting seat 21 is connected to the bottom of the intracavitary support 200, and then the first support frame 22 is adjusted in the left-right direction and the second support frame 23 is adjusted in the up-down direction, so that the driving wheel 10 corresponds to the driving device 300 located on the front side of the magnetic resonance magnet 100, so that the driving shaft 20 on the driving wheel 10 can be accurately connected to the driving end of the driving device 300, thereby realizing the overall installation and adjustment of the intracavitary support 200.

[0037] Specifically, in this embodiment, the support seat 12 includes a first top plate 121 and a first bottom plate 122, and the first top plate 121 and the first bottom plate 122 are parallel to each other and parallel to the bottom surface of the endoluminal support 200. The first top plate 121 and the first bottom plate 122 are connected by a support column 123. The locking member 13 is arranged on the first top plate 121, and the locking member 13 partially passes through the first top plate 121 to achieve connection with the bottom surface of the endoluminal support 200. Among them, the fixing seat 11 is provided with a first screw rod 111, the first screw rod 111 is vertically arranged, the first screw rod 111 is arranged on the first bottom plate 122 and is fastened to the first bottom plate 122 through the first nut 112. The relative position of the first bottom plate 122 on the first screw rod 111 can be adjusted by loosening the first nut 112. For example, when the first bottom plate 122 descends, it will drive the first top plate 121 to descend together, and the endoluminal support 200 can be synchronously descended. It is understandable that the initial height of the support seat 12 can be designed according to actual application needs. The fixing seat 11 is also connected to the magnetic resonance magnet 100 through a plurality of first bolts 110, specifically connected to the front and rear outer walls of the magnetic resonance magnet 100, and the front and rear outer walls of the magnetic resonance magnet 100 should be provided with corresponding bolt mounting holes 2322.

[0038] Specifically, in this embodiment, the first mounting seat 21 includes a second top plate 211 and a first vertical plate 212, the second top plate 211 is parallel to the bottom surface of the endoluminal support 200, and the second top plate 211 is connected to the endoluminal support 200 through a plurality of second bolts 2111, for example, the connection method of the first top plate 121 and the bottom surface of the endoluminal support 200 through the locking member 13 can be referred to. The first vertical plate 212 is arranged on one side of the second top plate 211, the second top plate 211 and the first vertical plate 212 are perpendicular to each other, and the second top plate 211 and the first vertical plate 212 are an integrated connection structure. Among them, the lower part of the first vertical plate 212 is threaded with a third bolt 213; the first support frame 22 is located between the second top plate 211 and the first vertical plate 212, the upper end of the first support frame 22 is limitedly slid on the second top plate 211, and the end of the third bolt 213 away from the first vertical plate 212 is threadedly penetrated on the first support frame 22. By loosening or tightening the third bolt 213, the left and right position of the first support frame 22 can be adjusted.

[0039] Specifically, in this embodiment, the first support frame 22 includes a second bottom plate 221 and two first side plates 222 relatively arranged on the second bottom plate 221, and a U-shaped cavity is formed between the second bottom plate 221 and the two first side plates 222 for accommodating the second support frame. A groove 2220 is provided on the opposite surfaces of the two first side plates 222. The second support frame 23 includes a third bottom plate 231 and two second side plates 232 relatively arranged on the third bottom plate 231, and a U-shaped cavity is also formed between the third bottom plate 231 and the two second side plates 232 for accommodating the driving wheel 10. The assembly of the first support frame 22 and the second support frame 23 is realized through the groove 2220, for example, the two second side plates 232 are correspondingly limited and slidably arranged in the two grooves 2220.

[0040] Specifically, in this embodiment, the first position-limiting connecting shaft 2321 is provided on the opposite surfaces of the two second side plates 232, and the first sliding groove 2221 for the first position-limiting connecting shaft 2321 to penetrate therein and move up and down is provided in the corresponding groove 2220 on the two first side plates 222. The first position-limiting connecting shaft 2321 is in the shape of a bolt, and has a shaft body and a shaft cap. When the shaft body penetrates the first sliding groove 2221, the shaft cap is located outside the first sliding groove 2221 to limit the shaft body, so that the two second side plates 232 are limited in the corresponding grooves 2220 of the two first side plates 222, and can slide up and down along the first sliding groove 2221 in the groove 2220 without displacement. Furthermore, a fourth bolt 214 is threadedly penetrated on the second bottom plate 221, and the upper end of the fourth bolt 214 extends between the two first side plates 222 and is fixedly connected to the third bottom plate 231. By rotating the fourth bolt 214, the third bottom plate 231 can be controlled to move up or down, so that the two second side plates 232 thereon are driven to move up or down together through the third bottom plate 231, thereby adjusting the orientation of the driving wheel 10. In this embodiment, the setting of the first slide groove 2221 can not only enable the second support frame 23 to move stably in a predetermined direction, but also limit the moving distance of the second support frame 23.

[0041] Specifically, in this embodiment, the upper ends of the two first side plates 222 are each provided with a second limit connecting shaft 2222, and the second top plate 211 is correspondingly provided with a second slide groove 2110 for the second limit connecting shaft 2222 to penetrate therein and move left and right. Among them, the shape of the second limit connecting shaft 2222 is the same as the first limit connecting shaft 2321, and the details can be referred to the above description of the first limit connecting shaft 2321, which will not be repeated here. In this embodiment, the provision of the second slide groove 2110 can not only enable the first support frame 22 to move stably in a predetermined direction, but also limit the moving distance of the first support frame 22.

[0042] Specifically, in this embodiment, a second side plate 232 near the third bolt 213 is also provided with an avoidance groove 2320, and one end of the third bolt 213 away from the first vertical plate 212 is also extended into the avoidance groove 2320, which is used to provide a reasonable space for the movement of the third bolt 213 to avoid obstruction. Among them, both second side plates 232 are also provided with a mounting hole 2322 for mounting the drive wheel 10. The drive wheel 10 is usually provided with a drive shaft 20 for connecting with the drive end of the drive device 300. When the drive wheel 10 is installed on the second support frame 23 through the mounting hole 2322, the end of the drive shaft 20 near the drive device 300 should also pass through the first support frame 22 so as to achieve connection with the drive end of the drive device 300. Therefore, a avoidance recess 2223 should also be provided at the corresponding position of the first support frame 22. In this embodiment, the drive device 300 is, for example, a hand-cranked wheel. In actual application, the shaft head of the hand-cranked wheel is connected to the drive shaft 20 through a coupling.

[0043] Specifically, in this embodiment, Figures 10 to 12 As shown in , the magnetic resonance intracavitary support installation and adjustment mechanism also includes a tension adjustment component 3 arranged on the intracavitary support 200, and the tension adjustment component 3 is located on the side of the first positioning adjustment component 1 away from the second positioning adjustment component 2, so that when the driving wheel 10 is connected to the driven wheel 30 arranged on the intracavitary support 200 through the synchronous belt 40, the driven wheel 30 is driven to move to adjust the tension of the synchronous belt 40. When the driving wheel 10 is set to be connected to the synchronous belt 40 and the driven wheel 30 through transmission cooperation and the sliding seat 50 is arranged on the synchronous belt 40, the sliding seat 50 is driven to slide through the transmission cooperation of the driving wheel 10, the synchronous belt 40 and the driven wheel 30, and when the magnetic resonance bed 400 is installed on the sliding seat 50, the magnetic resonance bed 400 can be driven to move synchronously.

[0044] For example, in this embodiment, the intracavitary support 200 is provided with a first hollow groove 2001 at a corresponding position on a side (the rear side of the intracavitary support 200) away from the second positioning and adjusting component 2, and the bottom of the intracavitary support 200 is also provided with a positioning support 4, and the positioning support 4 is provided with a second hollow groove corresponding to the first hollow groove 2001, and the positioning support 4 is also provided with two oppositely distributed vertical plates 41 at the two opposite side edges of the second hollow groove. When the positioning support 4 is fastened to the bottom surface of the intracavitary support 200, the two opposite vertical plates 41 thereon pass through the first hollow groove 2001 and are located above the intracavitary support 200. The two opposite vertical plates 41 are correspondingly provided with a horizontal third slide groove 401. The driven wheel 30 is installed between the two vertical plates 41 through the fifth bolt 215, and the two ends of the fifth bolt 215 are correspondingly fastened and inserted in the two third slide grooves 401.

[0045] The tension adjustment assembly 3 includes a third screw 31, a third nut 32 and a sliding frame 33. The sliding frame 33 is connected to one side of the positioning bracket 4 through the cooperation of the third screw 31 and the third nut 32 and is located below the intracavitary bracket 200. The sliding frame 33 is located at the second hollow groove and corresponds to the second hollow groove. The sliding frame 33 has a concave cavity. Two extending arms extending upward are correspondingly provided at the two opposite side edges of the concave cavity. The two extending arms are both extended into the second hollow groove and respectively correspond to the two vertical plates 41 close to the positioning bracket 4, while the driven wheel 30 is located in the concave cavity of the sliding frame 33. The same end of the two extension arms is provided with a bent bayonet 331, and the two ends of the fifth bolt 215 are also correspondingly inserted into the two bayonet 331. When adjusting the driven wheel 30, it is necessary to loosen the fifth bolt 215 first, and then adjust the position of the sliding frame 33 in the first hollow groove 2001 by rotating the third nut 32 to move the third screw rod 31, and then pull the fifth bolt 215 to shift, thereby adjusting the position of the driven wheel 30, so that the synchronous belt 40 on the driven wheel 30 can reach a suitable tension in cooperation with the driving wheel 10.

[0046] Specifically, in this embodiment, Figure 5 , 6As shown in , 8, the magnetic resonance intracavitary support mounting and adjusting mechanism also includes a second mounting seat 5 provided on the intracavitary support 200, and the second mounting seat 5 is located between the first mounting seat 21 and the tension adjustment assembly 3; the first mounting seat 21 is connected to the intracavitary support 200 and can move horizontally forward and backward relative to the intracavitary support 200. For example, a plurality of fourth slide grooves 2112 are also provided on the second top plate 211, and a plurality of second bolts 2111 are correspondingly inserted into the plurality of fourth slide grooves 2112 to be fastened and connected with the bottom of the intracavitary support 200. When the plurality of second bolts 2111 are loosened, the second top plate 211 can be moved forward and backward by a suitable distance relative to the intracavitary support 200. The first mounting seat 21 also includes a second vertical plate, which is provided on the other side of the second top plate 211 and is located on the adjacent side of the second top plate 211 and the first vertical plate 212, and the second vertical plate is opposite to the second mounting seat 5, and the second top plate 211 and the first vertical plate 212 are both integrated with the second vertical plate. Among them, the shape and structure of the second mounting seat 5 are similar to those of the first mounting seat 21, and please refer to the corresponding drawings for details. A second screw rod 51 is threadedly penetrated on the second mounting seat 5, and one end of the second screw rod 51 away from the second mounting seat 5 is threadedly penetrated on the first mounting seat 21, and the second screw rod 51 is locked by a second nut. Specifically, one end of the second screw rod 51 away from the second mounting seat 5 is threadedly penetrated on the second vertical plate. A tensioning auxiliary wheel 53 for transmission connection with the synchronous belt 40 is provided in the second mounting seat 5. When a plurality of second bolts 2111 are loosened and the second top plate 211 can move forward and backward relative to the intracavitary stent 200, the second top plate 211 can be pulled closer to or away from the second mounting seat 5 by rotating the second nut 52 on the second screw rod 51, so as to facilitate further reasonable adjustment of the position of the driving wheel 10, and when the tension of the synchronous belt 40 needs to be adjusted, the tension of the synchronous belt 40 can also be adjusted under the action of the tensioning auxiliary wheel 53, and the application is very flexible.
