[0002] During a shoulder MRI examination, the shoulder joint is tilted in the human body, so positioning and positioning must be based on the joint's shape. For a normal patient, the upper limb being examined is straightened, placed flat on the bed, and secured with a sandbag.

[0003] However, there are often patients with humeral fractures or elbow fractures who are fixed with plaster at 90 degrees or less. At this time, the entire upper limb cannot be laid flat, but the upper humerus must be kept parallel to the bed surface. At this time, the patient's forearm will be placed on the stomach in a relaxed position, and the rise and fall of the abdomen with breathing will drive the movement of the entire upper limb, resulting in motion artifacts in the shoulder joint magnetic resonance imaging, resulting in a decrease in image quality and affecting the diagnostic results.

[0004] Therefore, the present application provides a shoulder joint magnetic resonance coil frame to solve the above problems. Utility Model Content

[0007] Preferably, the arc-shaped plate is provided with a plurality of guide grooves for movable insertion of the pad.

[0008] Preferably, the pad is fixedly connected to a limiting slider at one end close to the arc plate, and a limiting groove for movably plugging into the limiting slider is provided on the arc plate. The pad is aligned with the limiting groove and the guide groove through the limiting slider and is inserted horizontally. The pad can be inserted into the guide grooves at different angles on the lower arc plate to adjust the angle of fixation of the patient's forearm, thereby ensuring applicability to different patients.

[0009] Preferably, the limiting groove and the guide groove are communicated with each other.

[0010] Preferably, the flat plate, the arc-shaped plate and the support arm plate are integrally formed, and the flat plate is provided with a chamfer at an end away from the arc-shaped plate, and the support arm plate is provided with a chamfer at an end away from the arc-shaped plate.

[0011] The coil holder is integrally formed by fixing the flat plate, the arc-shaped plate and the support arm plate into a holder, and the holder is sleeved on the shoulder joint of the patient fixed with plaster, and the holder can fix the forearm while the upper arm humerus of the patient is placed on the bed surface, and the forearm is isolated from the abdomen, so that the forearm is not affected by the respiratory movement, and the patient's shoulder joint is guaranteed.

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0021] The present embodiment provides a shoulder joint magnetic resonance coil holder, as shown in Figures 1-5As shown, the coil holder includes a flat plate 1 and an arc-shaped plate 2 mounted at one end of the flat plate 1, and a support arm plate 3 fixedly connected to the end of the arc-shaped plate 2 away from the flat plate 1, and a spacer plate 4 arranged on the arc-shaped plate 2, the flat plate 1, the arc-shaped plate 2 and the support arm plate 3 are integrally formed, and the end of the flat plate 1 away from the arc-shaped plate 2 is provided with a chamfer, and the end of the support arm plate 3 away from the arc-shaped plate 2 is provided with a chamfer.

[0022] Specifically, the flat plate 1, the arc-shaped plate 2 and the support arm plate 3 form a bracket, and the flat plate 1, the arc-shaped plate 2 and the support arm plate 3 are integrally formed by machining, which is used to improve the overall strength of the bracket. The main function of the bracket is to lift the patient's forearm to isolate the forearm from the abdomen. In order to ensure that both shoulders can be used, no baffle is arranged on the upper part of all brackets. The arc-shaped plate 2 is arc-shaped and has only one side with a quarter of a circular arc. The plate placed on the bed surface is designed to be sloped from the arc shape inward. In this way, the patient's shoulder will not feel uncomfortable when the spacer plate 4 is placed under the patient's shoulder. The chamfers arranged on the support arm plate 3 and the flat plate 1 are mainly used to prevent scratching when the bracket is used to support the forearm.

[0023] A plurality of guide grooves 22 for the spacer plate 4 to movably insert are arranged on the arc-shaped plate 2, and a limiting slide block 41 is fixedly connected to the end of the spacer plate 4 close to the arc-shaped plate 2. A limiting groove 21 movably inserted with the limiting slide block 41 is arranged on the arc-shaped plate 2, and the limiting groove 21 and the guide groove 22 are in communication.

[0024] More specifically, the limiting groove 21 and the guide groove 22 are in communication with the limiting slide block 41 fixedly connected to the spacer plate 4, which is adapted to the limiting slide block 41. The spacer plate 4 is inserted through the limiting slide block 41 to align the limiting groove 21 and the guide groove 22. The spacer plate 4 can be inserted into the guide groove 22 of different angles on the lower arc-shaped plate 2 to adjust the angle of the fixed forearm of the patient, ensuring the applicability of different patients, thereby improving the comfort of the patient. The number of the insertion slots formed by the limiting groove 21 and the guide groove 22 is not less than five, and the angles of the spacer plate 4 inserted from top to bottom correspond to 55 degrees, 50 degrees, 45 degrees, 40 degrees and 35 degrees, respectively.

[0025] In use, the flat plate 1, the arc-shaped plate 2 and the support arm plate 3 are fixedly connected to form a bracket, and the bracket is sleeved on the shoulder joint of the patient with a plaster cast. The bracket can fix the forearm while the upper arm humerus is placed on the bed surface, and the forearm is isolated from the abdomen. The spacer plate 4 is inserted through the limiting slide block 41 to align the limiting groove 21 and the guide groove 22. The spacer plate 4 can be inserted into the guide groove 22 of different angles on the lower arc-shaped plate 2 to adjust the angle of the fixed forearm of the patient, ensuring the applicability of different patients, thereby improving the comfort of the patient.

[0026] The above merely provides the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and concept of the present application, can make equivalent replacements or changes within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
