Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a knee joint MR examination fixation device. Background Art

[0002] The knee joint is more susceptible to injury during human movement, and the anterior cruciate ligament is more easily damaged due to its thinness, causing knee instability and various functional disorders such as internal rotation, internal and external valgus, and hyperextension. The normal anterior cruciate ligament originates from the back of the medial surface of the lateral femoral condyle and is divided into two bundles. The anterior medial bundle is located above and the posterior lateral bundle is located below. It runs from the back to the inner front and lower part at a 15° angle to the sagittal plane and ends at the anterior part of the tibial intercondylar eminence and the anterior corners of the medial and lateral menisci. When the human knee joint is injured, an MR examination is required.

[0003] For example, Chinese patent publication number CN216628538U discloses a knee joint MR examination fixation device, comprising an examination table, support columns are fixedly installed on both sides of the top of the examination table, and lifting slots are provided on opposite sides of the two support columns. A lifting screw is rotatably provided inside the lifting slot, and a slider is threadedly sleeved on the outer side of the lifting screw. A cross bar is fixedly connected between the two sliders, and a slide groove is provided at the upper end of the cross bar, and a bidirectional screw is rotatably provided inside the slide groove, and a support block is threadedly sleeved on the outer side of the bidirectional screw, and an arc plate is fixedly connected to the top of the support block, and further comprising a drive assembly arranged on the cross bar for driving the bidirectional screw to rotate;

[0004] The technical solution recorded in this proposal is to provide a lifting screw, a drive motor, a belt, an arc plate and a cross bar, so that the lifting screw can be driven to rotate by starting the drive motor, thereby bending the calf; secondly, the device is provided with a slide groove at the top of the cross bar, and is provided with a bidirectional screw, a support block, and a driving assembly, so that the two support blocks can be moved closer to or away from each other, thereby adjusting the distance between the two legs. However, when this solution is in use, the height of both sides of the examination table is higher due to the provision of support columns, which makes the patient's legs easily blocked by the support columns when entering the examination table, thereby affecting the patient's lying flat on the examination table.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a knee joint MR examination fixation device is provided, in order to achieve a purpose with greater practical value. Utility Model Content
