Technical Field

[0001] The utility model relates to the field of medical auxiliary equipment, in particular to a joint fixing support frame for medical imaging detection. Background Art

[0002] Medical imaging, also known as imaging medicine or medical imaging, is the study of imaging techniques and processes for the non-invasive acquisition of the morphological structure, physiological function, and pathological state of internal organs or tissues of the human body or a part of it for medical treatment or research purposes. Images obtained using medical imaging equipment and technology are called medical images. When taking medical images, a fixed angle is often required to better display or compare the patient's test area. Currently, existing imaging studios often lack equipment to fix the patient's joints. Some patients with limb disabilities have difficulty moving, making it impossible for the patient's limbs to maintain a fixed position during the filming process, making filming more difficult. Therefore, designing a device that can fix the patient's joints can better facilitate image capture while reducing patient discomfort. Utility Model Content

Since fixing holes 43 are provided on the surfaces of the support arm 41 and the lifting rod 42, when the lifting rod 42 rises and falls and slides inside the support arm 41, it can drive the bracket 5 to follow the rise and fall, so that the height of the bracket 5 can be adjusted to facilitate the fixation of the limbs of patients of different heights. After the height adjustment of the bracket 5 is completed, the fixing pin 44 is inserted into the fixing hole 43 to fix the support arm 41 and the lifting rod 42, thereby keeping the height of the bracket 5 unchanged, which is convenient for image shooting.

[0025] See also Figure 4 The fixing component 6 includes a placement ring 61 fixedly installed at the front end of the bracket 5, a buckle 62 is installed on one side of the placement ring 61, and a restraining belt 63 is connected to the other side of the placement ring 61, and one end of the restraining belt 63 is inserted into the inside of the buckle 62.

[0026] During specific use: a placement ring 61 is installed at the front end of the bracket 5. The placement ring 61 is a semi-ring structure, which makes it easy to fit the curvature of the limb. By pulling the restraint belt 63 through the buckle 62 installed on one side of the placement ring 61, the restraint belt 63 is folded back so that the restraint belt 63 is fixed by the Velcro connected on the surface, so that the limb is fixed in the placement ring 61 at one end of the bracket 5, so that the patient's limb maintains a fixed posture, which is convenient for further image shooting.

[0027] See also Figure 3 The bracket 5 consists of a first connecting arm 51 and a second connecting arm 52. The first connecting arm 51 is hinged to the inside of the second connecting arm 52 through a rotating shaft 53 at one end. A worm gear 54 is fixedly installed in the middle of the rotating shaft 53. An adjusting wheel 55 is rotatably installed inside the second connecting arm 52. A worm 56 is installed at one end of the adjusting wheel 55, and the worm 56 is meshed with the worm gear 54.

[0028] During specific use: the bracket 5 is composed of a first connecting arm 51 and a second connecting arm 52. The first connecting arm 51 is hinged to the inside of the second connecting arm 52 through a rotating shaft 53, so that the first connecting arm 51 and the second connecting arm 52 can be movably connected. By rotating the adjusting wheel 55 inside the second connecting arm 52, the worm 56 is driven to rotate, and the rotation of the worm 56 drives the worm wheel 54 in the middle of the rotating shaft 53 to follow the rotation, thereby achieving angle adjustment between the first connecting arm 51 and the second connecting arm 52, which is convenient for the patient's limb bending, thereby realizing image shooting in different orientations according to needs.

[0029] See also Figure 2A bidirectional screw rod 7 is rotatably installed inside the mounting frame 2, a stepping motor 8 is fixedly installed at one end of the mounting frame 2, the output end of the stepping motor 8 is fixedly connected to one end of the bidirectional screw rod 7, the slider 3 is threadedly connected to the surface of the bidirectional screw rod 7, and the two sides of the slider 3 are connected to the limit blocks 31, and the inner wall of the mounting frame 2 is provided with slide grooves 21, and the limit blocks 31 are slidably installed inside the slide grooves 21.

[0030] During specific use: a bidirectional screw rod 7 is installed inside the mounting frame 2 for rotation. The stepping motor 8 at one end of the mounting frame 2 drives the bidirectional screw rod 7 to rotate. The rotation of the bidirectional screw rod 7 causes the two sliders 3 connected by threads to follow the rotation. Since the sliders 3 are connected on both sides with limit blocks 31 and the limit blocks 31 slide in the slide groove 21 opened on the inner wall of the mounting frame 2, when the bidirectional screw rod 7 rotates, the slider 3 slides along the bidirectional screw rod 7 under the limit of the limit block 31, so that the two sliders 3 are relatively close to or away from each other, which is convenient for driving the bracket 5 to move and convenient for supporting and fixing patients with different arm spans.

[0031] See also Figure 3 The bottom of the lifting rod 42 is rotatably connected to the bracket 5 through a shaft sleeve 9, and a locking knob 91 is installed at the bottom of the shaft sleeve 9.

[0032] During specific use: the bottom of the lifting rod 42 is rotatably connected to the bracket 5 through the shaft sleeve 9. When the locking knob 91 is loosened, the bracket 5 is rotated and adjusted at the bottom of the lifting rod 42 to achieve angle adjustment between the bracket 5 and the lifting rod 42, which is convenient for improving the flexibility of the bracket 5. After tightening the locking knob 91, the bracket 5 and the lifting rod 42 are locked and fixed.

[0033] See also Figure 3 The lifting rod 42, the first connecting arm 51 and the second connecting arm 52 are all made of PEEK material.

[0034] During specific use: the lifting rod 42, the first connecting arm 51 and the second connecting arm 52 are made of PEEK material. PEEK has excellent X-ray transmittance and will not show up under X-rays. Therefore, it can be used as an orthopedic external fixator. It has high strength, light weight, and X-ray transmittance, which is conducive to use in orthopedic surgery.

[0035] A support arm 41 is installed on the surface of the slider 3, and a lifting rod 42 is slidably installed at one end of the support arm 41. The bracket 5 is installed at the bottom of the lifting rod 42. Since fixing holes 43 are provided on the surfaces of the support arm 41 and the lifting rod 42, when the lifting rod 42 rises and falls and slides inside the support arm 41, it can drive the bracket 5 to follow the rise and fall, so that the height of the bracket 5 can be adjusted to facilitate the fixation of the limbs of patients of different heights. After the height adjustment of the bracket 5 is completed, the fixing pin 44 is inserted into the fixing hole 43 to fix the support arm 41 and the lifting rod 42, thereby keeping the height of the bracket 5 unchanged, which is convenient for image shooting.
