Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a shoulder joint and humerus integrated magnetic resonance coil. Background Art

[0002] The magnetic resonance coil is an essential component of an MRI system. It receives magnetic resonance signals during MRI to obtain multi-dimensional, multi-contrast images, providing rich tissue information for clinical use. It is responsible for receiving and transmitting radio frequency signals to generate images of the patient's body. Currently, when performing MRI of the shoulder joint and humerus in clinical practice, the coils used are split-body shoulder coils specifically for the shoulder joint, while the body coil wraps around the humerus. This prevents the shoulder joint and humerus from being completely enclosed during positioning, preventing the lesion from being centered in the coil. This results in poor lesion signal and compromises the MRI quality. Summary of the Invention

[0034] Compared with the prior art, the present invention has at least the following beneficial effects:

[0035] In the above scheme, a coil body and a wrist joint component are provided, and the coil body and the wrist joint component are flexible coils that are relatively soft as a whole. When in use, the shoulder joint component is placed on the top of the patient's shoulder joint, and the patient's entire arm is wrapped around the inner side of the coil body and the wrist joint component through the coil body and the wrist joint component, so that the patient's shoulder joint and humerus can be wrapped. Since the coil body and the wrist joint component are an integrated design, they are also wrapped as a whole during wrapping, so that the lesion position can be in the center of the coil, thereby improving the effect of magnetic resonance imaging, and the soft material of the flexible coil can fit the patient more closely and adapt to patients of different body shapes, thereby improving the accuracy and clarity of the scan, and the shoulder joints and humerus on both sides can be used.

[0036] By setting up a support frame and rotating the screw by turning the handle, the upper and lower threaded members are forced to move away from each other, and the limiting wheel is caused to slide on the inner side of the guide frame, and stops when it slides to the side where the arc-shaped protrusion 27 of the guide frame is adapted to the contour of the limiting wheel. The upper and lower threaded members are brought closer to each other by rotating the handle, and pressure is applied to the support frame by the limiting wheels on both sides, so that the two ends of the support frame continue to shrink inward, thereby increasing the clamping force on the patient's shoulder joint. At the same time, the second tightening member shrinks to clamp the patient's humerus and prevent the arm from falling out, thereby driving the coil body to fit closely with the patient's arm and shoulder joint, improving the clarity during scanning, and being able to deform according to the contour of the patient's arm and shoulder, so as to perform corresponding adaptation.

[0037] By setting a guide frame and a limiting wheel, the screw is rotated by turning the handle, so that the threaded parts on both sides are close to each other, causing the limiting wheels on the upper and lower sides to slide to one end of the guide frame. At this time, the limiting wheels on both sides are located between the two first thinning sections of the support frame, and the limiting wheels on both sides are close to each other, and tension is applied to the two ends of the support frame through the guide frame, so that the support frame can be stretched. At the same time, when the limiting wheel slides on the inner side of the guide frame, it will drive the pulling slider to slide synchronously, and then the downward bent spring piece of the connecting member is pulled into the interior of the first adapter plate through the guide wire, and then the first inner buckle section is pulled up through the connecting member, so that the first inner buckle sections on both sides cannot shrink inwardly. At this time, the coil body as a whole is in a stretched state, which makes it convenient to place the patient's arm on the inner side of the coil body, thereby improving the convenience of installing the coil body.

[0038] By setting the sponge board and the fixing strip, after completing the wrapping of the patient's shoulder joint and arm, the limit clips on both sides are contracted and inserted into the hole grooves of the fixing strips on both sides, and the positioning pins on both sides are inserted into the positioning holes at the corresponding positions of the fixing strips, so that the sponge board can be installed on one side of the part of the coil body wrapping the humerus, and the patient's chest and humerus are separated by the sponge board. One side of the sponge board is located at the patient's armpit, and the other side is located at the patient's elbow joint, so as to avoid the shoulder joint being affected by the patient's breathing and causing motion artifacts. At the same time, the upper and lower sides of the coil body are connected by the fixing strip, which can further improve the firmness of the coil body wrapping. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] like Figure 1 and Figure 3 As shown, an embodiment of the present invention provides an integrated magnetic resonance coil for shoulder joint and humerus, comprising a coil body 1, a shoulder joint component, a wrist joint component and a fastening assembly; the shoulder joint component and the wrist joint component are respectively arranged at both ends of the coil body 1; the coil body 1 and the wrist joint component are both flexible bodies; the coil body 1 comprises: a first shell 2 and a coil; the first shell 2 can be bent into a set shape to be wrapped around the shoulder joint and humerus; the coil is partially or completely arranged inside the first shell 2; the wrist joint component comprises: a second shell 3, the second shell 3 can be bent into a set shape The coil body 1 and the wrist joint component are in the shape of a flexible coil, which can be wrapped around the wrist joint. A Velcro can be provided on the surface of the wrist joint component. When wrapped around the patient's wrist, the wrist joint component is adhered and fixed to the patient's wrist by tightening the Velcro. The coil body 1 and the wrist joint component are a flexible coil as a whole, which can be wrapped around the patient's shoulder and the outside of the arm for magnetic resonance imaging; the second shell 3 is connected to the first shell 2; the fastening assembly includes: a first tightening member, which is fixed to one end of the first shell 2 close to the shoulder joint component, and the coil body 1 is tightened and fixed to the shoulder joint by the deformation tension of the first tightening member.

[0058] It also includes: a rubber bag 4; the first shell 2 includes: a shoulder joint portion, a humeral portion and a forearm joint portion in sequence; the end portion of the shoulder joint portion is connected to the shoulder joint component, and the end portion of the forearm joint portion is connected to the wrist joint component; the rubber bag 4 is arranged at the connection between the end portion of the shoulder joint portion and the shoulder joint component, and the rubber bag 4 is arranged to be an internal cavity and stretchable rubber bag. When the coil body 1 wraps the shoulder joint and the arm, the shoulder joint component of the coil body 1 covers the front and back sides of the shoulder. When the humeral component of the coil body 1 wraps the humerus, the humeral component will be wrapped around the outside of the humerus in a ring shape. At this time, the side edges between the humeral component and the shoulder joint component will be dislocated, that is, the position of the rubber bag 4. Through the setting of the rubber bag 4, the connection between the humeral component and the shoulder joint component can be maintained when dislocated.

[0059] By setting the coil body 1 and the wrist joint component, the coil body 1 and the wrist joint component are a flexible coil that is relatively soft as a whole. When in use, the shoulder joint component is placed on the top of the patient's shoulder joint, and the patient's entire arm is wrapped around the inner side of the coil body 1 and the wrist joint component through the coil body 1 and the wrist joint component, so that the patient's shoulder joint and humerus can be wrapped. Since the coil body 1 and the wrist joint component are an integrated design, they are also wrapped as a whole during wrapping, so that the lesion position can be in the center of the coil, thereby improving the effect of magnetic resonance imaging, and the soft material of the flexible coil can fit the patient more closely and adapt to patients of different body shapes, thereby improving the accuracy and clarity of the scan, and the shoulder joints and humerus on both sides can be used.

[0060] like Figures 3 to 9 As shown, the first tightening member includes: a support frame 5, a guide frame 6, a limiting wheel 7 and a driving mechanism; the support frame 5 is an elastic body and is arranged along the curved surface of the first shell 2; at least two guide frames 6 are arranged at intervals on the support frame 5; the guide frame 6 has a guide hole, and a limiting wheel 7 is movably arranged in the guide hole; the limiting wheel 7 is connected to the driving mechanism and is driven to move in the guide hole by the driving force of the driving mechanism; the two adjacent limiting wheels 7 are driven by the driving mechanism to move in the same or opposite directions to drive the two adjacent guide frames 6 closer to or away from each other, so that the support frame 5 is in a compressed state or a stretched state, and the guide hole has a first hole wall and a second hole wall that are relatively arranged, and the limiting wheel 7 moves between the first hole wall and the second hole wall; an arc-shaped protrusion 27 is provided on the first hole wall, and an arc-shaped convex groove corresponding to the arc-shaped protrusion 27 is provided on the second hole wall, so that the limiting wheel 7 moves on both sides of the arc-shaped protrusion 27 through the arc-shaped convex groove. In the initial state, the limiting wheels 7 on the upper and lower sides are both located at the end of the guide frame 6 away from the arc-shaped protrusion 27.

[0061] The driving mechanism comprises: a threaded member 10 and a screw rod 11; a limiting wheel 7 is fixedly connected to a threaded member 10, the threaded member 10 has a threaded through hole, and the threaded through holes of two adjacent threaded members 10 have opposite thread rotation directions, and the threaded member 10 is divided into two parts, and the part where the threaded member 10 is connected to the limiting wheel 7 is set as a square structure, and the bottom of the square structure is set as a cylinder, and the inner sides of the cylinder and the square structure are both provided with thread grooves that match the threads of the screw rod 11. The overall length of the threaded member 10 is increased by the cylinder, and the contact area between the threaded member 10 and the screw rod 11 is increased, thereby increasing the height that the threaded member 10 can rise when it is connected to the screw rod 11, thereby reducing the length of the screw rod 11 and preventing the screw rod 11 from being too long and affecting the normal use of the coil body 1; the two ends of the screw rod 11 are respectively threadedly connected to the two adjacent threaded through holes, and the outer side of the screw rod 11 is fixedly connected to a handle, and the threaded member 10 is slidably connected to the inner side of the handle, and the outer side of the handle The wall is provided with an anti-slip groove to facilitate operation by medical personnel. Two guide rail frames 6 are symmetrically arranged along the center line of the support frame 5. Two centrally symmetrical first thinning sections 12 are provided on the support frame 5. The first thinning section 12 is an elastomer. The first tightening member also includes: a pulling slider 8, a guide wire 9, a first adapter plate 13 and a connecting member 14; a sliding groove is provided on the first hole wall and / or the second hole wall, and the pulling slider 8 is arranged in the guide hole and is slidably connected to the sliding groove; the first adapter plate 13 is fixedly installed on the first shell 2. The first adapter plate 13 is made of plastic as a whole to avoid artifacts in magnetic resonance imaging, and is elastic and is arranged along the side of the first shell 2; one end of the first adapter plate 13 is fixedly connected to the support frame 5; one end of the connecting member 14 extends into the movable hole and is slidably connected to the other end of the first adapter plate 13, and the other end of the connecting member 14 is connected to the first shell 2; arc-shaped spring pieces are respectively provided at both ends of the connecting member 14.

[0062] The guide rail frame 6, the support frame 5 and the first adapter plate 13 are provided with movable holes that are interconnected; the movable hole is connected to the guide hole; the guide wire 9 is slidably set in the movable hole; the guide wire 9 is an elastic body, one end of which is connected to the pulling slider 8, and the other end is connected to the connecting member 14. The bending directions of the arc-shaped springs at both ends of the connecting member 14 are opposite. The connecting member 14 is located on the inner side of the rubber bag 4. The first adapter plate 13 is connected to the first inner buckle section 15 through the connecting member 14. The end of the connecting member 14 close to the guide wire 9 is provided with a downwardly bent spring. When the sheet contracts, the downward-bending spring piece flips downward at the end away from the guide wire 9, and the end of the connecting piece 14 close to the first inward buckle section 15 is provided with an upward-bending spring piece. When the upward-bending spring piece contracts, the upward-bending spring piece flips upward at the end close to the first inward buckle section 15. When the spring pieces at both ends of the connecting piece 14 contract and bend, the connecting piece 14 is Z-shaped as a whole, so that when the part of the coil body 1 surrounding the humerus is misaligned with the part surrounding the shoulder joint, the first adapter plate 13 can remain connected to the first inward buckle section 15.

[0063] The first tightening member also includes: a first inner buckle section 15, a second inner buckle section 20, a second adapter plate 22 and a third adapter plate 24; the first inner buckle section 15 has a first end and a second end; the first end of the first inner buckle section 15 is rotatably connected to the other end of the connecting member 14, and the second end of the first inner buckle section 15 is fixedly connected to the second adapter plate 22; the second adapter plate 22 and the third adapter plate 24 are respectively installed on the first shell 2 and arranged along the side of the first shell 2; the second adapter plate 22 and the third adapter plate 24 are connected by the second inner buckle section 20; the first adapter plate 13, the second adapter plate 22 and the third adapter plate 24 are respectively provided with a plurality of second thinning sections 21, and the second thinning section 21 is an elastomer. By deforming the second thinning section 21, the first adapter plate 13, the second adapter plate 22 and the third adapter plate 24 can fit better with the human body, so that the coil body 1 can fit more closely with the patient.

[0064] By setting up the support frame 5, when wrapping the patient's shoulder joint, the shoulder joint component is placed on the top of the patient's shoulder joint, and the component of the coil body 1 wrapping the shoulder joint covers the outside of the patient's shoulder joint, and the patient's humerus, forearm and wrist are placed in the corresponding parts of the coil body 1 and the wrist joint component in turn, so that the component of the coil body 1 wraps the patient's humerus, the component wrapping the forearm joint wraps the patient's forearm, and the wrist joint of the patient is wrapped by the wrist joint component, so that the patient's entire arm is wrapped on the inner side of the coil body 1.

[0065] At this time, the screw rod 11 is rotated by turning the handle, so that the threaded parts 10 on the upper and lower sides move away from each other, thereby causing the limiting wheel 7 to slide on the inner side of the guide rail frame 6. Since the support frame 5 is in a contracted state when it is not under force, the limiting wheel 7 stops applying pressure to the guide rail frame 6, so that the support frame 5 gradually contracts, thereby driving the parts of the coil body 1 surrounding the shoulder joint to contract, clamping the patient's shoulder joint, and at the same time, when the limiting wheel 7 slides, it will lose contact with the traction slider 8, thereby stopping limiting the traction slider 8. Since one end of the guide wire 9 The guide wire 9 is fixed on the outside of the pulling slider 8. When the pulling slider 8 loses its limit, the guide wire 9 rebounds and drives the pulling slider 8 to slide. At this time, the first inner buckle segment 15 loses the tension limit of the guide wire 9 as a whole and shrinks, thereby driving the connecting member 14 to slide out from the inside of the first adapter plate 13. The two spring pieces provided on the connecting member 14 will shrink, and the connecting member 14 and the first inner buckle segment 15 are rotationally connected. Therefore, when the first inner buckle segment 15 shrinks, the connecting member 14 will not twist, and the connecting member 14 will gradually change with the overall shrinkage of the first inner buckle segment 15. The two spring pieces provided on the connecting piece 14 are contracted, and finally the connecting piece 14 is Z-shaped, so that the part of the coil body 1 that wraps around the humerus wraps around the patient's humerus, completing the preliminary fixation of the patient's arm. At this time, the patient's arm can be adjusted again so that the arm is in a suitable position on the inner side of the coil body 1 and fits tightly with the coil body 1; after the adjustment is completed, the handle is continuously rotated to slide the limiting wheels 7 on the upper and lower sides to the side where the arc-shaped protrusion 27 is adapted to the contour of the limiting wheel 7. At this time, the limiting wheels 7 on both sides are located at the thinned part of the support frame 5 and are connected. On one side of the first adapter plate 13, the handle is rotated to make the upper and lower threaded members 10 approach each other, and then pressure is applied to the guide rail frame 6 through the limiting wheels 7 on both sides, so that the guide rail frames 6 on both sides are close to each other, so that the two ends of the support frame 5 continue to shrink inward, thereby increasing the clamping force on the patient's shoulder joint. At the same time, the first adapter plate 13 will be deformed at multiple second thinning sections 21 to perform corresponding deformation according to the contour of the patient's shoulder joint, thereby ensuring close contact between the coil body 1 and the patient's shoulder joint, and ensuring the final effect of magnetic resonance imaging.

[0066] By turning the handle to rotate the screw 11, the threaded members 10 on both sides are brought closer to each other, causing the upper and lower limiting wheels 7 to slide to the position as shown in FIG. Figure 8When the limiting wheels 7 on both sides drive the guide rail frames 6 on both sides to approach each other, the guide rail frames 6 exert tension on both ends of the support frame 5, so that the support frame 5 can be stretched. At the same time, when the limiting wheels 7 slide on the inner side of the guide rail frames 6, it will drive the pulling slider 8 to slide synchronously, and then the downwardly bent spring piece of the connecting piece 14 is pulled into the interior of the first adapter plate 13 through the guide wire 9. The connecting piece 14 is limited by the first adapter plate 13 so that the connecting piece 14 is deformed into a straight shape, that is, Figure 7 As shown, the first inner buckle section 15 is pulled up by the connecting piece 14, so that the first inner buckle sections 15 on both sides cannot shrink inward. At this time, the coil body 1 is in a stretched state as a whole, which makes it convenient to place the patient's arm on the inner side of the coil body 1, thereby improving the convenience of installing the coil body 1.

[0067] like Figures 6 to 9 As shown, the fastening assembly further includes: a second tightening member and a third tightening member; the second tightening member and the third tightening member are both arranged along the curved surface of the first shell 2, and are respectively connected to the first inner buckle section 15 and the second inner buckle section 20; the second tightening member and the third tightening member have the same structure;

[0068] The second tightening member includes: a large contraction section 16, a small contraction section 17, a first arc piece, a fixed arc plate 18 and a plurality of connecting arc plates; the first arc piece and the connecting arc plate are both elastic bodies; the first inward buckle section 15 also includes a third end, the third end of the first inward buckle section 15 is connected to the large contraction section 16 through the first arc piece, the large contraction section 16 is connected to the small contraction section 17 through the connecting arc plate; the small contraction section 17 is connected to the fixed arc plate 18 through the connecting arc plate; the first arc piece includes: an upper arc piece and a lower arc piece; the upper arc piece and the lower arc piece are connected to form an S-shape, W-shape or wave shape, the upper arc piece is in a stretched state in the initial state, and when the upper arc piece contracts, the first inward buckle section 15 can be flipped downward, the lower arc piece is in a contracted state in the initial state, and when the lower arc piece is stretched, the first inward buckle section 15 can be further flipped downward, the upper arc piece is connected to the lower arc piece, and the upper arc piece and the lower arc piece can simultaneously cause the first inward buckle section 15 to flip downward, thereby increasing the flip angle of the first inward buckle section 15;

[0069] The third tightening member is also provided with a large contraction section 16, a small contraction section 17, a first arc piece, a fixed arc plate 18 and multiple connecting arc plates. The third tightening member has an opposite elasticity to the second tightening member, so that the third tightening member is in a state of being stretched outward as a whole.

[0070] By setting the second tightening member and the third tightening member, after the limiting wheels 7 on both sides move away from each other and the pulling slider 8 loses its limit, the guide wire 9 is in a powerless state, thereby stopping the tension on the connecting member 14, and the upper arc piece at one end of the first inner buckle section 15 contracts, causing the first inner buckle section 15 to flip downward, and the lower arc piece at one end of the large contraction section 16 is stretched, further causing the first inner buckle section 15 to flip inward, and at the same time, the large arc plate at one end of the small contraction section 17 and the small arc plates at both ends of the fixed arc plate 18 contract, causing the second tightening member to contract as a whole, thereby clamping and limiting the patient's arm, and the third tightening member is in a powerless state. An inward buckle section 15 has a large flip angle and can buckle the patient's arm inward, thereby driving the coil body 1 to deform, wrap around the patient's arm and clamp it, while preventing the patient's arm from falling out from the inside of the coil body 1; when the connecting member 14 is pulled by the guide wire 9, the connecting member 14 will gradually slide toward the inside of the first adapter plate 13, and the second tightening member will gradually stretch and stop when the downward-bent spring piece of the connecting member 14 enters the inside of the first adapter plate 13. The upward-bent spring piece of the connecting member 14 is stretched under the action of the first inward buckle section 15, so that the connecting member 14 is straight.

[0071] When the second tightening member contracts, the wrist joint member is wrapped around the patient's wrist through the Velcro of the wrist joint member, and the Velcro is tightened and bonded to complete the wrapping and fixation of the patient's wrist. At the same time, since the wrist joint member is connected to the member of the coil body 1 that wraps around the forearm joint, it will simultaneously drive the member that wraps around the forearm joint to wrap around the patient's forearm, thereby driving the third tightening member to contract through the third adapter plate 24. Since a plurality of second thinning sections 21 are provided on the surface of the second adapter plate 22, when the second tightening member and the third tightening member contract, the second adapter plate 22 will be deformed according to the contour of the patient's arm to fit and adapt to the patient's arm, thereby improving the tightness of the coil body 1 and the patient's arm. The third tightening member is in a stretched state under normal circumstances, so that the coil body 1 can be propped up, making it easier for the patient's arm to be placed inside the coil body 1.

[0072] like Figure 2 and Figure 6As shown, the top of the first inner buckle section 15 is fixedly connected with a positioning pin, and the positioning pin is divided into two parts. The end connected to the first inner buckle section 15 is a long cylindrical structure, and the end away from the first inner buckle section 15 is a disc-shaped structure. The diameter of the disc is larger than the diameter of the long cylinder. Since the first inner buckle section 15 is symmetrically arranged, one end of the first inner buckle section 15 on the other side is fixedly connected to a limiting clamp. The limiting clamp is an elastic structure and can shrink inward under external force. The limiting clamp after shrinkage is cylindrical. The positioning pin and the limiting clamp extend from the inside of the coil body 1 and are exposed on the outside of the coil body 1. The positioning pin and the limiting clamp are also provided at the same position of the third tightening member. The outer side of the limiting clamp is sleeved with a fixing strip, and one side of the fixing strip is fixedly connected There is a sponge board, which is integrated with the fixing strip. The fixing strip is provided with a hole groove that matches the diameter of the limiting clamp after contraction at the position of the limiting clamp. After the limiting clamp is contracted, it can be separated from the fixing strip through the hole groove, so that the sponge board can be removed from one side of the coil body 1. A plurality of positioning holes are provided on the side of the fixing strip away from the limiting clamp. The positioning holes are composed of connected large circular holes and small circular holes. The diameter of the large circular hole is adapted to the diameter of the positioning pin disc, and the diameter of the small circular hole is adapted to the diameter of the long cylindrical portion of the positioning pin. The positioning pin can enter the positioning hole through the large circular hole, and when the long cylindrical portion of the positioning pin enters the small circular hole, the positioning pin disc is limited, so that the positioning pin cannot be removed from the positioning hole of the fixing strip.

[0073] By setting the sponge board and the fixing strip, after completing the wrapping of the patient's shoulder joint and arm, the limiting clamps on both sides are contracted and inserted into the hole grooves of the fixing strips on both sides. After the coil body 1 is wrapped, the coil body 1 is provided with a positioning pin and the two sides of the limiting clamp part fit the inner side of the patient's arm, so that the positioning pin will face the fixing strip, and by making the positioning pins on both sides enter the positioning holes at the corresponding positions of the fixing strip, the sponge board can be installed on one side of the part of the coil body 1 wrapping the humerus, and the patient's chest and humerus are separated by the sponge board. One side of the sponge board is located at the patient's armpit, and the other side is located at the patient's elbow joint, so as to avoid the shoulder joint being affected by the patient's breathing and causing motion artifacts. At the same time, the upper and lower sides of the coil body 1 are connected by the fixing strip, which can further improve the firmness of the wrapping of the coil body 1.

[0074] The working principle of the technical solution provided by the present invention is as follows:

[0075] During use, the coil body 1 and the fastening assembly are in the initial state. At this time, the coil body 1 is set in a stretched state, which makes it easy to place the patient's shoulder joint and arm into the inner side of the coil body 1. By placing the shoulder joint component on the top of the patient's shoulder joint, the component of the coil body 1 wrapped around the shoulder joint covers the outside of the patient's shoulder joint, and the patient's humerus, forearm and wrist are placed in the corresponding parts of the coil body 1 and the wrist joint component in turn, so that the component of the coil body 1 wrapped around the humerus wraps the patient's humerus, the component wrapped around the forearm joint wraps the patient's forearm, and the wrist joint component wraps the patient's wrist joint, so that the patient's entire arm is wrapped inside the coil body 1. Since the coil body 1 and the wrist joint component are designed as an integral whole, they are also wrapped as a whole, so that the lesion position can be in the center of the coil, thereby improving the effect of magnetic resonance imaging.

[0076] At this time, the screw 11 is rotated by turning the handle, causing the upper and lower threaded members 10 to move away from each other, and then the limiting wheel 7 slides on the inner side of the guide frame 6, and stops when it slides to the side where the arc-shaped protrusion 27 is adapted to the contour of the limiting wheel 7. At this time, the handle is turned to make the upper and lower threaded members 10 approach each other, and pressure is applied to the support frame 5 through the limiting wheels 7 on both sides, so that the two ends of the support frame 5 shrink inward, thereby increasing the clamping force on the patient's shoulder joint. At the same time, the first adapter plate 13 will be deformed at multiple second thinning sections 21 to perform corresponding deformation according to the contour of the patient's shoulder joint, thereby ensuring close contact between the coil body 1 and the patient's shoulder joint, and ensuring the final effect of magnetic resonance imaging. After the limiting wheels 7 on both sides move away from each other and the pulling slider 8 loses its limit, the guide wire 9 is in an active state, thereby stopping applying tension to the connecting part 14, and the upper arc piece at one end of the first inner buckle section 15 contracts, causing the first inner buckle section 15 to flip downward, and the lower arc piece at one end of the large contraction section 16 is stretched, further causing the first inner buckle section 15 to flip inward. At the same time, the large arc plate at one end of the small contraction section 17 and the small arc plates at both ends of the fixed arc plate 18 contract, causing the second tightening part to contract as a whole, thereby clamping and limiting the patient's arm. The first inner buckle section 15 has a large flip angle and can buckle the patient's arm inward, thereby driving the coil body 1 to deform, wrap around and clamp the patient's arm, and prevent the patient's arm from falling out from the inside of the coil body 1.

[0077] The wrist joint component is wrapped around the patient's wrist through the Velcro of the wrist joint component, the Velcro is tightened and glued to complete the wrapping and fixation of the patient's wrist. At the same time, since the wrist joint component is connected to the component of the coil body 1 that wraps around the forearm joint, it will simultaneously drive the component that wraps around the forearm joint to wrap around the patient's forearm. And since the third adapter plate 24 is located on the inner side of the component that wraps around the forearm joint, when the component that wraps around the forearm joint fits the patient's forearm, the third adapter plate 24 also fits the patient's forearm, thereby driving the third tightening member to shrink through the third adapter plate 24. A plurality of second thinning sections 21 are provided on the surface of the second adapter plate 22, which will promote the contraction of the second and third tightening members when they shrink. The second adapter plate 22 is deformed according to the contour of the patient's arm to fit and adapt to the patient's arm. After completing the wrapping of the patient's shoulder joint and arm, the limit clamps on both sides are contracted and inserted into the hole grooves of the fixing strips on both sides, and the positioning pins on both sides are inserted into the positioning holes at the corresponding positions of the fixing strips, so that the sponge plate can be installed on one side of the part of the coil body 1 that wraps around the humerus. The patient's chest is separated from the humerus by the sponge plate. One side of the sponge plate is located at the patient's armpit and the other side is located at the patient's elbow joint, so as to avoid the shoulder joint being affected by the patient's breathing and causing motion artifacts. At the same time, the upper and lower sides of the coil body 1 are connected by the fixing strip, which can further improve the firmness of the wrapping of the coil body 1.
