Description

Technical Field

[0001] The invention relates to an image scanning auxiliary device, in particular to an image scanning auxiliary positioning device for a shoulder joint. Background Art

[0002] MRI's multi-directional, multi-sequence imaging method can display more detailed anatomical structures and provide more diagnostic information, which provides an accurate imaging basis for the diagnosis of shoulder joint diseases.

[0003] In shoulder MRI examination, the patient lies in the supine position with the head forward and the affected side as close to the center of the main magnetic field as possible. The affected shoulder is relaxed and placed naturally at the side of the body. In order to improve the image quality, technicians usually require the patient's arm to remain in an external rotation position (i.e., palm facing up), avoid internal rotation (palm facing down) as much as possible, keep the body consistent with the bed, keep the affected arm level with the shoulder, raise the healthy side appropriately so that the affected shoulder joint is close to the coil, and prevent the bilateral arms from contacting the magnet bore wall and the body. The affected side should be kept at a certain distance from the thorax to reduce the impact of thorax motion artifacts, etc. However, it is difficult for patients to achieve and maintain these extremely detailed body position requirements, which results in low image quality.

[0057] The shoulder joint image scanning auxiliary positioning device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0058] Reference Figure 1 to Figure 2 As shown, the shoulder joint image scanning auxiliary positioning device provided according to an embodiment of the present invention includes a hand support seat 10, an inflatable cushion 20, a gripping member 30 and an elastic squeezing ball 40.

[0059] Specifically, the hand support seat 10 has a bracket H101 suitable for accommodating an upper limb. The bracket can be made of plastic material and is usually constructed into a strip structure. Preferably, the bottom surface of the bracket is a plane, which is convenient for placing it on the bed surface of the examination bed. The shape and size of the bracket H101 can adapt to the upper limbs of patients of different body shapes and provide stable support.

[0060] The inflatable cushion 20 is arranged in the bracket H101 to support the patient's upper limbs and adjust the height of the upper limbs. The inflatable cushion 20 is made of soft and durable medical grade materials and can provide comfortable support for the upper limbs in an inflated state.

[0061] The gripping piece 30 is arranged at one end of the hand support seat 10, and the height position of the gripping piece 30 in the vertical direction is adjustable, so that the patient's palm can be held in an external rotation position. The gripping piece 30 is an auxiliary piece for ensuring the external rotation position of the palm. The user places the arm on the inflatable cushion 20 in the bracket H101, and holds the gripping piece 30 with the palm facing up to keep the arm in an external rotation position. The gripping piece 30 can be adjusted in the vertical direction to meet the needs of different patients, and can also adapt to the height requirements of the arm. For example, if the arm is kept level with the shoulder, at this time, the gripping piece 30 is adjusted to a suitable height position to facilitate the patient to hold the gripping piece 30 naturally. Imaging examination in a natural and comfortable state is conducive to improving image quality.

[0062] The elastic squeezing ball 40 is connected to the inflatable cushion 20 through the air tube 401 to inflate and deflate the inflatable cushion 20. The elastic squeezing ball 40 is made of high-quality rubber material and has good elastic recovery performance and durability. The elastic squeezing ball 40 can be used to inflate and deflate the inflatable cushion 20 as needed, thereby adjusting the thickness of the inflatable cushion 20. By adjusting the thickness of the inflatable cushion 20, the support height of the upper limb can be accurately controlled.

[0063] The following briefly describes the use of the shoulder joint image scanning auxiliary positioning device.

[0064] Instruct the patient to assume a supine position and enter the magnet head first, with the affected side as close to the center of the main magnetic field as possible.

[0065] Guide the patient to naturally place the affected upper limb in the bracket H101 of the hand support seat 10, so that the upper arm can be evenly supported by the inflatable cushion 20. Instruct the patient to hold the gripping member 30 in a comfortable posture, ensuring that the palm remains in an external rotation position (palm facing up).

[0066] By controlling the elastic squeezing ball 40, the inflation amount of the inflatable cushion 20 is adjusted so that the patient's upper limb reaches an ideal height level with the shoulder. If necessary, the height position of the gripping member 30 is adjusted to ensure that the patient's arm remains in a natural and relaxed state. In this state, scanning can be performed.

[0067] According to the shoulder joint image scanning auxiliary positioning device provided by the embodiment of the present invention, the problem that it is difficult for patients to accurately place and maintain the arm position during the shoulder joint examination is effectively solved through the hand support seat 10, the inflatable cushion 20, the gripping piece 30 and the elastic squeezing ball 40. Among them, the bracket H101 of the hand support seat 10 provides positioning support for the upper limbs and is isolated from the magnet hole wall and the thorax. The inflatable cushion 20 can flexibly adjust the arm height according to the patient's body shape and examination requirements to ensure that the affected side is level with the shoulder; the adjustable height gripping piece 30 not only guides the patient's palm to maintain an external rotation position (palm up), but also prevents the arm from rotating internally during the examination; the elastic squeezing ball 40 is connected to the inflatable cushion 20 through the trachea 401, so that the technician can accurately adjust the inflation amount of the inflatable cushion 20 at any time, thereby achieving fine-tuning of the arm position. This structural design not only meets the strict requirements of the shoulder joint MRI examination for body position, but also takes into account the comfort of the patient to maintain the body position for a long time, which can effectively improve the quality of the scanned image.

[0068] In some embodiments of the present invention, the palm rest 10 includes a bottom wall 101, a first side wall 102 and a second side wall 103. The first side wall 102 and the second side wall 103 are oppositely arranged on both sides of the bottom wall in the width direction and define the bracket H101 together with the bottom wall.

[0069] In this embodiment, the hand rest 10 forms a stable and reliable bracket H101 space through the three-sided enclosure structure of the bottom wall 101 and the first side wall 102 and the second side wall 103. This structural design not only provides all-round support and protection for the upper limbs, ensuring that the patient's upper limbs can be comfortably and stably maintained in the correct position, but also uses the first side wall 102 and the second side wall 103 to isolate the arm from the thorax and the magnet hole wall, so that there is a certain distance between the arm and the thorax and the magnet hole wall, thereby significantly reducing the impact of thorax movement and magnet hole wall vibration on image quality and reducing the generation of artifacts.

[0070] In one embodiment of the present invention, a first sliding hole H102 is provided at one end of the first side wall 102, and a second sliding hole H103 is provided at the second side wall 103. The first sliding hole H102 and the second sliding hole H103 are arranged opposite to each other and both extend in the up-down direction.

[0071] The gripping member 30 includes a first slide bar 301, a gripping object 303, and a first locking knob 302. The first slide bar 301 is inserted into the first slide hole H102 and the second slide hole H103. One end of the first slide bar 301 has a first stopper 3011 located outside the first side wall 102, which is used to prevent the first slide bar 301 from falling out of the first slide hole H102. The other end of the first slide bar 301 has a first external thread, which is used to cooperate with the locking knob.

[0072] The gripping object 303 is sleeved on the first slide bar 301 and is located between the first side wall 102 and the second side wall 103 for the patient to hold. The gripping object 303 can be made of a soft material for comfortable holding. The first locking knob 302 cooperates with the first external thread to selectively lock the first slide bar 301 at different height positions.

[0073] During use, the first locking knob 302 is loosened, and the first slide bar 301 can move freely up and down to adjust the height position of the first slide bar 301. When the first slide bar 301 is adjusted to a suitable position, the first locking knob 302 can be tightened, and the first slide bar 301 and the gripping object 303 are kept at the current height position, so as to facilitate the patient to hold.

[0074] In this embodiment, the height position of the gripping member 30 is precisely adjusted and reliably locked by the first sliding bar 301, the gripping object 303 and the first locking knob 302. The sliding design of the first sliding bar 301 ensures the smoothness of the adjustment process, and the first locking knob 302 ensures the convenience of use and adjustment and the reliability of locking.

[0075] In one embodiment of the present invention, an elbow pressure piece 50 is further included. The elbow pressure piece 50 is disposed on the hand rest 10 and is configured to be able to tilt and slide upward in a direction from one end to the other end of the hand rest 10 so as to apply a predetermined pressure to the patient's arm so that the arm is placed on the inflatable cushion 20.

[0076] That is to say, the elbow pressure piece 50 can slide on the hand support seat 10, and the front and rear position and the upper and lower height position of the elbow pressure piece 50 can be changed by sliding. In the specific use process, the patient puts the arm into the bracket H101, and keeps the palm facing up, and adjusts the height of the arm through the inflatable cushion 20, which is actually kept flush with the shoulder, and then holds the gripping member 30, and finally, slides the elbow pressure piece 50 in the front and rear direction. Since the diameter of the arm from the palm to the shoulder gradually increases, the elbow pressure piece 50 can contact the arm when it slides to a certain position and exerts a certain pressure on the arm. When the pressure is appropriate, the elbow pressure piece 50 can be fixed and maintained at this position. In this way, the elbow pressure piece 50 can be used to apply a predetermined pressure to the arm.

[0077] In this embodiment, the elbow pressure member 50 realizes pressure control on the patient's arm through controllable tilting and sliding, and this pressure control can effectively reduce motion artifacts during the examination process and improve image quality. In addition, while ensuring pressure controllability, the operation convenience not only meets the clinical requirements for image quality, but also ensures the safety and comfort of the examination process.

[0078] In one embodiment of the present invention, the first side wall 102 is provided with a third sliding hole H104, the second side wall 103 is provided with a fourth sliding hole H105, the first sliding hole H102 and the second sliding hole H103 are arranged opposite to each other and both extend upwardly in a direction from one end to the other end of the hand rest seat 10. The inclination angles of the third sliding hole H104 and the fourth sliding hole H105 provide a guarantee for the inclined sliding of the elbow pressure member 50.

[0079] The elbow pressure member 50 includes a second slide bar 501 and a second locking knob 502. The second slide bar 501 is inserted into the third slide hole H104 and the fourth slide hole H105. One end of the second slide bar 501 has a second stop block 5011 located outside the first side wall 102. The second stop block 5011 can prevent the second slide bar 501 from escaping from the third slide hole H104, thereby ensuring safety and reliability in use. The other end of the second slide bar 501 has a second external thread, which is used to cooperate with the second locking knob 502 to achieve a position locking function. The second locking knob 502 cooperates with the second external thread to selectively lock the second slide bar 501 at different positions.

[0080] When in use, loosen the second locking knob 502 to allow the second slide bar 501 to move freely in the inclined third slide hole H104 and fourth slide hole H105, adjust the position of the second slide bar 501 according to the position of the patient's arm, and when the appropriate pressure position is reached, tighten the second locking knob 502. At this time, the second slide bar 501 can exert a certain pressure on the arm.

[0081] This embodiment realizes precise control and adjustment of elbow pressure through the design of the inclined third sliding hole H104 and the fourth sliding hole H105, as well as the matching second sliding rod 501 and the second locking knob 502. The design of the inclined third sliding hole H104 and the fourth sliding hole H105 ensures the gradual change of pressure adjustment and realizes precise adjustment. The cooperation of the second sliding rod 501 and the second locking knob 502 ensures the smooth controllability of the adjustment process and the reliability of position locking. The entire structural design is simple and practical, and the adjustment is convenient and quick.

[0082] In one embodiment of the present invention, the elbow pressure piece 50 further includes a covering 503 made of a soft material. The covering 503 is wrapped around the second sliding bar 501 and is located between the first side wall 102 and the second side wall 103 .

[0083] The covering 503 can be made of soft plastic material, such as EVA material, silicone material, rubber material, etc. When the second slide bar 501 slides to a suitable position, the covering 503 contacts the patient's arm, thereby providing a softer and more comfortable compression effect, making the use process more comfortable and friendly to the patient, and the pressure is not too large to prevent discomfort.

[0084] In one embodiment of the present invention, the top surfaces of the first side wall 102 and the second side wall 103 are provided with scale lines and a plurality of raised positioning marks, the scale lines extend along the length direction of the palm rest 10, and a plurality of positioning marks are distributed on one side of the scale lines at equal intervals along the length direction of the palm rest, and the scale lines and positioning marks are made of nano-developing materials that are developed in magnetic resonance images.

[0085] In actual image scanning operations, technicians can use scale lines and positioning marks to accurately locate the specific position of the patient's upper limbs and align the positions of the shoulders on both sides. In addition, the display in the magnetic resonance image can be used as a reference point for spatial positioning to help doctors locate the arm and shoulder joints more accurately. In this way, the precise positioning, recording and reproduction functions of the position in the image examination are realized, and a reliable spatial reference is provided for image interpretation, which significantly improves the accuracy and repeatability of the examination.

[0086] In one embodiment of the present invention, grooves are provided on the inner sides of the first side wall 102 and the second side wall 103. A detachable pad is provided in the groove. The pad is made of a hydrophilic material with good water absorption and air permeability.

[0087] In this embodiment, the soft padding material can increase the comfort of the contact surface between the patient and the bracket and reduce the discomfort caused by the examination. The detachable nature of the pad makes cleaning and disinfection very convenient, and the pad can be replaced or cleaned in time according to the usage to ensure good sanitary conditions. In addition, the hydrophilic material can effectively absorb the sweat generated by the patient during the examination, keeping the contact surface dry and comfortable.

[0088] In some embodiments of the present invention, a plurality of vacuum suction cups are provided at the bottom of the hand support 10 for adsorbing and fixing on the examination bed surface. During use, the vacuum suction cups at the bottom of the hand support 10 are used to adsorb and fix the positions of both sides of the examination bed surface, ensuring that the hand support 10 remains stable during the inspection process, and has the characteristics of easy operation and quick assembly and disassembly.
