Description

Technical Field

[0001] This application relates to the field of medical devices, for example to an installation fixture for installing the front or rear ring of a medical device. Background Technology

[0002] Currently, the protective housing of a magnetic resonance imaging (MRI) system consists of a front ring and a rear ring. Due to their large size and weight, the front and rear rings present significant installation challenges. Taking the installation of the front ring as an example, it typically requires two people to lift it and align the mounting holes with the corresponding studs of the three-way adjustment mechanism on the front housing. Because the preset positions of the studs in the three-way adjustment mechanism deviate from the actual adjustment mechanism, the stud positions must be continuously adjusted while lifting and stabilizing the front ring to align it with the mounting holes. The size and weight of the front ring make the entire installation process very difficult.

[0003] Currently, there is no technical solution that can facilitate this installation process.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides an installation fixture for installing the front or rear ring of a medical device, comprising:

[0007] A base for fixing to a fixed position of a medical device, wherein the base is provided with a first positioning mechanism corresponding to the arrangement of multiple adjustment mechanisms on the protective cover;

[0008] A positioning part is disposed on the base. The positioning part includes a second positioning mechanism for cooperating with the first positioning mechanism to define the arrangement orientation of the positioning part, and a third positioning mechanism for indicating the actual position of the adjustment mechanism of the protective cover under the arrangement orientation.

[0009] The installation fixture for the front or rear ring of medical equipment provided in this application allows for the adjustment of the actual position of the adjustment mechanism on the protective cover based on the third positioning mechanism, enabling the front or rear ring of the medical equipment to be quickly installed in place, reducing the installation difficulty of the front or rear ring of the medical equipment, and improving installation efficiency.

[0010] In some embodiments, the tooling includes:

[0011] A first fastener is inserted through the first end of the base and is used to fix the base to the medical device;

[0012] The second fastener is inserted through the second end of the base and is used to fix the base to the medical device;

[0013] The first and second ends of the base are opposite ends.

[0014] The base can be effectively fixed to the medical device using the first and second fixing members.

[0015] In some embodiments, the base is provided with multiple screw holes, and the mounting fixture includes:

[0016] One or more fixing blocks, each having multiple screw holes;

[0017] The first positioning screw passes through the screw hole to connect the fixing block and the base, and is used to fix the fixing block and the base.

[0018] The second positioning screw passes through the screw hole and connects to the fixing block, used to fix the fixing block to the medical device.

[0019] The base can be fixed to the medical device using the movable fixing blocks.

[0020] In some embodiments, the base is provided with fixing holes, and the mounting fixture further includes:

[0021] A connector passes through the fixing hole and is rotatably connected to the base for connecting the base to a fixable position on the medical device.

[0022] A rotating fixing member is connected to the plug-in member and is used to drive the plug-in member to rotate.

[0023] In some embodiments, the positioning part further includes:

[0024] A rotating arm has a first end rotatably connected to the base, and a second end of the rotating arm, opposite to the first end, extends out of the edge of the base. A third positioning mechanism is disposed at the second end, and a second positioning mechanism is disposed between the first end and the second end. By rotating the rotating arm, its orientation can be adjusted to calibrate the position of the adjustment mechanism under different orientations simultaneously. This method is simple to operate and reduces costs.

[0025] In some implementations...

[0026] The base is provided with a first connection hole;

[0027] The first end of the rotating arm is rotatably connected to the base via a connecting element. The connecting element includes a connecting rod fixed to the first connecting hole and a rotating guide sleeve sleeved on the outside of the connecting rod and in clearance fit with the connecting rod. The rotating arm is connected to the rotating guide sleeve. The rotating arm and the base are rotatably connected via the connecting rod and the rotating guide sleeve. At the same time, the clearance fit between the rotating guide sleeve and the connecting rod prevents the rotating arm from moving in the radial direction of the connecting rod, ensuring the positioning accuracy of the third positioning mechanism.

[0028] In some embodiments, the first end is located at the end of the rotating guide sleeve away from the base and is provided with a second connecting hole. The connecting element further includes an anti-slip sleeve, which is sleeved on the outside of the connecting rod and passes through the second connecting hole. The anti-slip sleeve abuts against the end of the rotating guide sleeve away from the base. The connecting rod is provided with a locking structure for locking against the anti-slip sleeve. The locking structure on the connecting rod and the anti-slip sleeve prevent the connecting rod from slipping during fixing, further ensuring the positioning accuracy of the third positioning mechanism.

[0029] In some embodiments, the first connecting hole is a countersunk hole, the connecting rod is connected to the smaller diameter portion of the countersunk hole, and the rotating guide sleeve is also embedded in the larger diameter portion of the countersunk hole. By embedding the rotating guide sleeve in the larger diameter portion of the countersunk hole, the larger diameter portion can limit the radial movement of the rotating guide sleeve, further ensuring the positioning accuracy of the third positioning mechanism.

[0030] In some embodiments, the first positioning mechanism is located on a circle with the same radius as the rotation center of the rotating arm. By setting the first positioning mechanism to be located on a circle with the same radius as the rotation center of the rotating arm, the second positioning mechanism can be fixed relative to the rotating arm, simplifying the layout of the second positioning mechanism, thereby simplifying the structure of the installation fixture and making it easier to maintain.

[0031] In some embodiments, the first positioning mechanism is located on a circle with a different radius centered on the rotation center of the rotating arm, and the second positioning mechanism is movable between the first end and the second end. By setting the first positioning mechanism to be located on a circle with a different radius centered on the rotation center of the rotating arm, and the second positioning mechanism being movable between the first end and the second end, the design flexibility of the installation tooling is increased.

[0032] In some embodiments, the first positioning mechanism is configured as a limiting hole or a limiting groove, and the second positioning mechanism is configured as a limiting rod that is inserted into the first positioning mechanism. The limiting rod can extend or retract in the extension direction of the limiting rod or move relative to the rotating arm to achieve cooperation and discooperation with the first positioning mechanism.

[0033] In some embodiments, the rotating arm is further provided with a third connecting hole and a guide sleeve communicating with the third connecting hole and located between the rotating arm and the base. The guide sleeve is connected to the rotating arm. The limiting rod passes through the guide sleeve and the third connecting hole. One end of the limiting rod exposed in the third connecting hole is configured as an operating end. A first limiting structure is provided inside the guide sleeve, and a second limiting structure is provided on the limiting rod. The first and second limiting structures cooperate to prevent the limiting rod from dislodging from the guide sleeve. By providing the guide sleeve, the axial and radial positional accuracy of the limiting rod can be ensured when the rotating arm is in different orientations, thereby ensuring the positioning accuracy of the third positioning mechanism.

[0034] In some embodiments, the base is provided with a reference plane facing the rotating arm, and the guide sleeve abuts between the rotating arm and the base to keep the distance between the rotating arm and the reference plane constant in different orientations. By setting the guide sleeve to abut between the rotating arm and the base to keep the distance between the rotating arm and the reference plane constant in different orientations, the consistency of the third positioning mechanism's position with the reference plane when the rotating arm is in different orientations can be improved, ensuring the positioning accuracy of the third positioning mechanism.

[0035] In some embodiments, the third positioning mechanism is a positioning hole or a positioning rod.

[0036] In some embodiments, the positioning rod is telescopic or movable relative to the positioning part in the extension direction of the positioning rod, and the end of the positioning rod is provided with a slot or a socket. The adjustment mechanism for fixing the protective cover on the medical device includes a mounting post, and the slot or socket can be sleeved on the outside of the mounting post and is clearance-fitted with the mounting post.

[0063] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0064] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0065] In some implementations, such as Figure 1 As shown, an installation fixture is provided for installing the front or rear ring of a medical device, comprising:

[0066] A base 100 is used to fix it to a fixed position on a medical device. The base 100 is provided with a first positioning mechanism 101 corresponding to the arrangement orientation of multiple adjustment mechanisms on the protective cover. A positioning part 200 is provided on the base 100. The positioning part 200 includes a second positioning mechanism 201 for cooperating with the first positioning mechanism 101 to define the arrangement orientation of the positioning part 200 and a third positioning mechanism 202 for indicating the actual position of the adjustment mechanism under the arrangement orientation.

[0067] The installation fixture provided in this application is used for the installation of the front or rear ring of a medical device. The arrangement orientation of the positioning part 200 can be defined by the cooperation of the first positioning mechanism 101 and the second positioning mechanism 201. This arrangement orientation is the same as the arrangement orientation of a certain adjustment mechanism on the protective cover of the medical device, and also the arrangement orientation of a certain installation position on the front or rear ring. The position of the third positioning mechanism 202 in this arrangement orientation corresponds to the installation position of the front or rear ring in this arrangement orientation. Therefore, the actual position of the adjustment mechanism is adjusted based on the position of the third positioning mechanism 202, so that the position of the adjustment mechanism corresponds to the installation position on the front or rear ring. This enables the front or rear ring to be installed quickly, reduces the installation difficulty of the front or rear ring of the medical device, and improves the installation efficiency.

[0068] The medical equipment can include magnetic resonance imaging systems, computed tomography (CT) equipment, and positron emission tomography (PET) equipment. The front and rear rings of medical equipment are generally large and heavy. Different mounting positions are set on the circumference of the front and rear rings, and mounting holes or posts are provided at these positions for use with adjustment mechanisms to secure the front and rear rings.

[0069] Taking a magnetic resonance imaging system as an example, the mounting fixture provided in this application for mounting the front or rear loop of the medical device can be adjusted based on the third positioning mechanism 202. Figure 2 The positions of the four first studs 001 of the three-way adjustment mechanism of the front shell (protective cover) shown and / or as follows: Figure 3 The actual positions of the four second studs 002 of the three-way adjustment mechanism of the rear shell (protective cover) shown are such that... Figure 4 The four first mounting holes 003 and / or as shown in the front ring Figure 5 The four second mounting holes 004 of the rear ring shown are installed in one go, reducing the installation difficulty of the front or rear ring of the magnetic resonance imaging system and improving installation efficiency. In use, the base 100 of the mounting fixture provided in this application can be fixed on the body coil of the magnetic resonance imaging system, that is, the fixable position of the medical device includes the body coil of the magnetic resonance imaging system.

[0070] In practical applications, the installation fixture provided in this application includes a fixing structure for fixing the base 100 to a fixable position of the medical device. The fixing structure can be movably connected to the base 100 or fixedly connected to the base 100. Taking the movably connected case as an example, the fixing structure is connected to the base 100 by means of screws or other connection methods.

[0071] In practical applications, such as Figure 1 As shown, the base 100 may also include a handle 102 for easy hand-held installation of the fixture.

[0072] In some implementations, such as Figure 6 As shown, the fixing structure includes:

[0073] A first fastener 1011 is inserted through the first end of the base 100 and is used to fix the base 100 to the medical device;

[0074] The second fastener 1012 is inserted through the second end of the base 100 and is used to fix the base 100 to the medical device.

[0075] The first and second ends of the base 100 are opposite ends.

[0076] The base 100 can be effectively fixed to the medical device by means of the first fastener 1011.

[0077] Taking a fixed structure movably connected to the base 100 as an example, in one embodiment, the base 100 includes:

[0078] A first fixing part is disposed at the first end of the base 100;

[0079] The fixing structure includes a first fixing member 1011, which passes through the first fixing part and is used to fix the base 100 to the medical device; and / or

[0080] The base 100 includes a second fixing part disposed at the second end of the base 100;

[0081] The fixing structure includes a second fixing member 1012, and a first fixing member 1011 passes through the first fixing part for fixing the base 100 to the medical device;

[0082] The first and second ends of the base 100 are opposite ends.

[0083] In some implementations, such as Figure 7 As shown, the first fixing part can be a screw hole, and the first fixing member 1011 can be a fixing block 10111, a first positioning screw 10112, and a second positioning screw 10113. In one embodiment, the base 100 is provided with multiple screw holes, and the fixing structure includes:

[0084] One or more fixing blocks 10111, which are provided with multiple screw holes;

[0085] The first positioning screw 10112 passes through the screw hole to connect the fixing block 10111 to the base 100, and is used to fix the fixing block 10111 to the base 100;

[0086] The second positioning screw 10113 passes through the screw hole and connects to the fixing block 10111, which is used to fix the fixing block 10111 to the medical device.

[0087] In practical applications, the second positioning screw 10113 is located on the part of the fixing block 10111 that extends out of the base 100.

[0088] The base 100 can be fixed to the medical device by means of the movable fixing block 10111.

[0089] The second positioning screw 10113 corresponds to the screw hole on the medical device, such as Figure 8As shown, the base 100 can be fixed to the medical device.

[0090] In some implementations, such as Figure 7 As shown, the second fixing part can be a fixing hole, and the second fixing member 1012 can be a plug-in member 10121 and a rotating fixing member 10122.

[0091] In one embodiment, the base 100 is provided with a fixing hole, and the fixing structure includes:

[0092] The connector 10121 passes through the fixing hole on the base 100 and is rotatably connected to the base 100, for connecting the base 100 to a fixable position on the medical device;

[0093] The rotating fixing member 10122 is connected to the plug-in member 10121 and is used to drive the plug-in member 10121 to rotate.

[0094] In one embodiment, the medical device and the rotating fixing member 10122 are respectively located at both ends of the plug member 10121 and on both sides of the base 100.

[0095] The base 100 can be fixed to the radio frequency coil via the movable connector 10121 and the rotating fixing member 10122.

[0096] In one embodiment, the fixing hole on the base 100 can be provided on the fixing plate that is movably connected to the base 100. The fixing plate is connected to the base 100 by means of screws and screw holes. The fixing plate extends outside the base 100, and the fixing hole is provided on the part outside the base 100. The plug 10121 can pass through the fixing hole and be fixedly connected to the medical device.

[0097] In one embodiment, the connector 10121 can be a screw. The end of the connector 10121 can correspond to a screw hole on a medical device (such as a screw hole on the body coil), for example... Figure 9 As shown.

[0098] In some implementations, such as Figure 10 As shown, the positioning part 200 further includes:

[0099] A rotating arm 203 is provided, with its first end rotatably connected to the base 100, and its second end, which is opposite to the first end, extending out of the edge of the base 100. A third positioning mechanism 202 is provided at the second end, and a second positioning mechanism 201 is provided between the first end and the second end.

[0100] In some embodiments, the first positioning mechanism 101 can be a fourth connecting hole, and the second positioning mechanism 201 can be a third connecting hole, such as... Figure 10 As shown, four are provided on the base 100.

[0101] A fourth connecting hole, the positioning part 200 includes:

[0102] The rotating arm 203 has a third connecting hole in the middle and a third positioning mechanism 202 at the second end;

[0103] The four fourth connecting holes on the base 100 are used to connect to the third connecting hole in the middle of the rotating arm 203 at different times.

[0104] By rotating the rotating arm 203, the orientation of the rotating arm 203 can be adjusted, so as to calibrate the position of the adjustment mechanism under different orientations at the same time. The operation is simple and the cost is reduced.

[0105] In some implementations, such as Figure 11 As shown,

[0106] The base 100 is provided with a first connection hole;

[0107] The first end of the rotating arm 203 is rotatably connected to the base 100 through a connecting element. The connecting element includes a connecting rod 2031 fixed to the first connecting hole and a rotating guide sleeve 2032 sleeved on the outside of the connecting rod 2031 and in clearance fit with the connecting rod 2031. The rotating arm 203 is connected to the rotating guide sleeve 2032.

[0108] The rotating arm and the base are connected by the connecting rod 2031 and the rotating guide sleeve 2032. At the same time, the rotating guide sleeve 2032 and the connecting rod 2031 are fitted with a clearance to prevent the rotating arm 2031 from moving in the radial direction of the connecting rod 2031, thus ensuring the positioning accuracy of the third positioning mechanism 202.

[0109] The connecting rod 2031 has a connecting end at one end and an operating end at the other end. The first end of the rotating arm 203 is provided with a second connecting hole. The connecting end of the connecting rod 2031 passes through the second connecting hole on the rotating arm 203 and enters the first connecting hole on the base 100. By operating the operating end of the connecting rod 2031, the connecting rod 2031 and the rotating guide sleeve 2032 are fixed on the base 100, thereby realizing the rotatable connection between the rotating arm 203 and the base 100.

[0110] The connecting end and the operating end of the connecting rod 2031 can be detachable or fixed together.

[0111] In some implementations, such as Figure 11 As shown, the connecting element further includes:

[0112] The rotating guide sleeve 2032 is hollow, with one end sealed and having a through hole, and the other end open. The open end of the rotating guide sleeve 2032 is located on the rotating arm 203, and the open end corresponds to the second connecting hole on the rotating arm 203. The connecting rod 2031 passes through the rotating guide sleeve 2032, and the operating end of the connecting rod 2031 is located on the side of the rotating arm 203 opposite to the rotating guide sleeve 2032. The connecting end of the connecting rod 2031 can extend through the through hole to connect with the first connecting hole. A boss is provided on the circumference of the connecting rod 2031, and the boss can abut against the sealed bottom to restrict the axial movement of the rotating guide sleeve 2032.

[0113] The rotating arm 203 is rotatably connected to the base 100 by the connecting rod 2031 and the rotating guide sleeve 2032. At the same time, the rotating guide sleeve 2032 and the connecting rod 2031 are clearance-fitted to prevent the rotating arm 203 from moving in the radial direction of the connecting rod 2031, thus ensuring the positioning accuracy of the third positioning mechanism 202.

[0114] In some implementations, such as Figure 11 As shown, the first end of the rotating arm 203 is located at the end of the rotating guide sleeve 2032 away from the base 100, and is provided with a second connecting hole. The connecting element also includes a detachment sleeve 2033, which is sleeved on the outside of the connecting rod 2031 and passes through the second connecting hole. The detachment sleeve 2033 abuts against the end of the rotating guide sleeve 2032 away from the base 100. The connecting rod 2031 is provided with a locking structure for locking the detachment sleeve 2033.

[0115] By using the locking structure on the connecting rod 2031 and the anti-slip sleeve 2033, the connecting rod 2031 can be prevented from slipping during fixing, thus further ensuring the positioning accuracy of the third positioning mechanism 202.

[0116] In one implementation, such as Figure 11 As shown, the locking structure on the connecting rod 2031 is stepped, with the thicker part fitting against the rotating guide sleeve 2032 and the thinner part passing through the anti-detachment sleeve 2033.

[0117] In some implementations, such as Figure 11 As shown, the first connecting hole is a countersunk hole. The connecting rod 2031 is connected to the smaller diameter portion of the countersunk hole, and the rotating guide sleeve 2032 is also embedded in the larger diameter portion of the countersunk hole. By embedding the rotating guide sleeve 2032 into the larger diameter portion of the countersunk hole, the larger diameter portion can limit the radial movement of the rotating guide sleeve 2032, further ensuring the positioning accuracy of the third positioning mechanism 202.

[0118] In some embodiments, the first positioning mechanism 101 is located on a circle with the same radius as the rotation center of the rotating arm 203. By setting the first positioning mechanism 101 to be located on a circle with the same radius as the rotation center of the rotating arm 203, the second positioning mechanism 201 can be fixedly set relative to the rotating arm 203, simplifying the arrangement of the second positioning mechanism 201, thereby simplifying the structure of the installation fixture and making it easier to maintain.

[0119] In some embodiments, the first positioning mechanism 101 is located on a circle with a different radius centered on the rotation center of the rotating arm 203, and the second positioning mechanism 201 is movable between the first end and the second end. By setting the first positioning mechanism 101 to be located on a circle with a different radius centered on the rotation center of the rotating arm 203, and the second positioning mechanism 201 to be movable between the first end and the second end, the design flexibility of the installation tooling is increased.

[0120] In practical applications, the second positioning mechanism 201 can be movable between the first end and the second end. In this case, the position of the first positioning mechanism 101 is located on circles with different radii centered on the rotation center of the rotating arm 203. In one embodiment, there can be multiple first positioning mechanisms 101, which can be divided into different groups. Each group is located on circles with different radii centered on the rotation center of the rotating arm 203 to adapt to different assembly structure requirements.

[0121] In some implementations, such as Figure 12 As shown, the first positioning mechanism 101 is configured as a limiting hole or a limiting groove, and the second positioning mechanism 201 is configured as a limiting rod that is inserted into the first positioning mechanism 101. The limiting rod can extend or retract in the extension direction of the limiting rod or move relative to the rotating arm 203 to achieve cooperation and discooperation with the first positioning mechanism 101.

[0122] In some implementations, such as Figure 12As shown, the rotating arm 203 is also provided with a third connecting hole and a guide sleeve 2041 communicating with the third connecting hole and located between the rotating arm 203 and the base 100. The guide sleeve 2041 is connected to the rotating arm 203. The limiting rod passes through the guide sleeve 2041 and the third connecting hole. The end of the limiting rod exposed in the third connecting hole is configured as an operating end. A first limiting structure 20411 is provided inside the guide sleeve 2041, and a second limiting structure 2016 is provided on the limiting rod. The first limiting structure 20411 and the second limiting structure 2016 cooperate to prevent the limiting rod from dislodging from the guide sleeve 2041. The first limiting structure 20411 can be an annular inner protrusion provided inside the guide sleeve 2041, and the second limiting structure 2016 can be an annular outer protrusion provided outside the limiting rod. By setting the guide sleeve 2041, the positional accuracy of the limit rod in the axial and radial directions can be guaranteed when the rotating arm 203 is in different arrangement positions, thereby ensuring the positioning accuracy of the third positioning mechanism 202.

[0123] In some implementations, such as Figure 12 As shown, a detachment prevention kit 2042 is also provided in the third connecting hole. The detachment prevention kit 2042 is sleeved on the outside of the limiting rod and passes through the third connecting hole. The detachment prevention kit 2042 abuts against the end of the guide sleeve 2041 away from the base 100. The limiting rod is provided with a stepped structure for limiting the position of the detachment prevention kit 2042. In some embodiments, the base 100 is provided with a reference plane facing the rotating arm 203, and the guide sleeve 2041 abuts between the rotating arm 203 and the base 100 so that the distance between the rotating arm 203 and the reference plane remains constant in different arrangement positions.

[0124] By setting the guide sleeve 2041 to abut between the rotating arm 203 and the base 100, the distance between the rotating arm 203 and the reference plane remains constant when the rotating arm 203 is in different orientations. This can improve the consistency of the position of the third positioning mechanism 202 with the reference plane when the rotating arm 203 is in different orientations, and ensure the positioning accuracy of the third positioning mechanism 202.

[0125] In some embodiments, the third positioning mechanism 202 is a positioning hole, and the adjustment mechanism of the protective cover is provided with a mounting hole. When the center line of the mounting hole is aligned with the center line of the positioning hole, the mounting hole is in its actual position. Alternatively, the adjustment mechanism of the protective cover is provided with a mounting rod, and when the axis of the mounting rod is aligned with the center line of the positioning hole, the mounting rod is in its actual position.

[0126] In some embodiments, the third positioning mechanism 202 is a positioning rod, and the adjustment mechanism of the protective cover is provided with a mounting hole. When the center line of the mounting hole is aligned with the axis of the positioning rod, the mounting hole is in the actual position. Alternatively, the adjustment mechanism of the protective cover is provided with a mounting rod, and when the axis of the mounting rod is aligned with the axis of the positioning rod, the mounting rod is in the actual position.

[0127] In some embodiments, the end of the positioning rod is provided with a slot or socket. The positioning rod is telescopic in its extension direction or movable relative to the positioning part 200. The adjustment mechanism of the protective cover includes a mounting post. The slot or socket can be fitted onto the outside of the mounting post and has a clearance fit with the mounting post. In this embodiment, the clearance fit between the slot or socket and the mounting post ensures the positioning accuracy of the mounting post.

[0128] In some implementations, such as Figure 13 As shown, a positioning rod 2011 is vertically connected to the end of the positioning part 200. The end face of the positioning rod 2011 is provided with a slot extending inward along the length direction of the positioning rod 2011 and perpendicular to the end of the positioning part 200.

[0129] When the positioning part 200 includes the rotating arm 203, the positioning rod 2011 can pass through Figure 13 The positioning rod locking block 2012, wing nut 2013, and slip bolt 2014 shown are fixed on the rotating arm 203, or they can be integrally formed with the rotating arm 203.

[0130] The shape of the positioning rod 2011 can be as follows Figure 14 As shown, it can also be other structures.

[0131] Taking the protective cover of a magnetic resonance imaging system as an example, the installation fixture provided in this embodiment for positioning the front or rear ring of a medical device during installation is used as follows: Figure 14-15 As shown, it is installed on the body coil to help adjust the position of the four mounting posts (first stud 001) of the front shell three-way adjustment mechanism and / or the position of the four mounting posts (second stud 002) of the rear shell three-way adjustment mechanism. When using it, you can first use the installation tool to adjust the position of the mounting rod (first stud 001) of the front shell three-way adjustment mechanism, then disassemble it and reinstall it to adjust the position of the four mounting posts (second stud 002) of the rear shell three-way adjustment mechanism. After adjusting the position, disassemble the installation tool and install the front ring and the rear ring.

[0133] The installation fixture provided in this application for installing the front or rear ring of a medical device allows for the rapid installation of the front or rear ring of the medical device by adjusting the actual position of the adjusting mechanism of the protective cover based on the third positioning mechanism 202, thereby reducing the installation difficulty of the front or rear ring of the medical device and improving installation efficiency.
