Description

Technical Field

[0001] The utility model relates to the field of medical rehabilitation equipment, in particular to a detection bracket used for musculoskeletal ultrasonic evaluation. Background Art

[0002] Musculoskeletal ultrasound (MSKUS) is an ultrasound diagnostic technology used in the musculoskeletal system. Different from traditional ultrasound applications such as the abdomen and heart, MSKUS focuses on imaging diagnosis in specialized fields such as bone and joint surgery, rheumatology, rehabilitation, and neurosurgery. Since Medonald and other scholars first used ultrasound technology to diagnose musculoskeletal diseases in 1972, MSKUS has developed into one of the main clinical imaging diagnostic technologies alongside X-rays, CT, and MRI.

[0003] The advantage of musculoskeletal ultrasound is that it can provide real-time dynamic images, which is suitable for the musculoskeletal system that is closely related to movement. It can display the morphological changes and interactions of joints, bones, muscles and tendons in real time when the patient is performing active, passive or resistance exercise, which is helpful for the diagnosis of movement diseases and impingement syndrome. In addition, musculoskeletal ultrasound has no clear contraindications, no radiation damage, is easy to operate, can be examined at the bedside, and doctor-patient interaction and communication can be carried out during the examination, which is more comfortable for both doctors and patients.

[0004] However, musculoskeletal ultrasound also has limitations. As ultrasound cannot penetrate bones, its field of view is limited and it cannot fully display the anatomical structure of the entire joint. In addition, the examination effect of musculoskeletal ultrasound is closely related to the doctor's experience. When performing musculoskeletal ultrasound examination, the doctor needs to hold the ultrasound probe in his hand all the time. Long-term use will cause wrist soreness and muscle stiffness, so it is impossible to maintain a high quality of work, which will affect the accuracy and efficiency of diagnosis to a certain extent.

[0005] In this context, the design and application of probe supports have become the key to improving the efficiency and accuracy of musculoskeletal ultrasound evaluation. There is an urgent need for a probe support that can stabilize the ultrasound probe, reduce the doctor's technical dependence, and allow more precise positioning and image acquisition, thereby improving the accuracy and efficiency of diagnosis.

DETAILED DESCRIPTION

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0029] See also Figure 1 - Figure 7 In this embodiment, a detection bracket for musculoskeletal ultrasonic evaluation is involved, which is specifically used to provide a stable platform so that the ultrasonic probe 4 can be accurately positioned and operated when performing musculoskeletal ultrasonic examination. This detection bracket is particularly suitable for situations that require long-term or complex position operations, such as sports medicine, rheumatology, orthopedic surgery planning and rehabilitation medicine. It is designed to reduce operator fatigue and improve the accuracy and efficiency of the diagnostic process. Specifically comprising: a frame 1, a circular track 2 and a clamping module 3, the bottom of the frame 1 is symmetrically provided with two groups of support rods 11, the track is mounted on the upper ends of the two groups of support rods 11, the clamping module 3 is slidably adapted to the circular track 2 and is fixed with the ultrasonic probe 4;

[0030] The clamping module 3 comprises a sliding seat 31 , a connecting arm 32 and a clamping portion 33 . The sliding seat 31 is provided with a guide wheel 311 , and the outer contour of the guide wheel 311 is adapted to the guide bar 23 provided in the annular track 2 .

[0031] Specifically, in this embodiment, the frame 1 is used to support the annular track 2, and the patient's body is supported by the base of the frame 1. During the musculoskeletal ultrasound process, the patient needs to be located on the inner side of the annular track 2, and the doctor operates on the side. The sliding seat 31 of the clamping module 3 is slidably adapted to the annular track 2, and the sliding seat 31 is connected to the clamping part 33 through the connecting arm 32. The ultrasonic probe 4 is fixed on the clamping part 33, so that the ultrasonic probe 4 can be adjusted at any angle of 360° around the patient. The doctor does not need to hold the ultrasonic probe 4 by hand for a long time, and only needs to operate the position of the ultrasonic probe 4 by dragging and swinging the hand, and perform a full range of musculoskeletal ultrasound evaluation on the patient. The detection bracket of this embodiment not only improves the convenience and comfort of operation of musculoskeletal ultrasound evaluation, but also helps to reduce errors caused by doctor fatigue, thereby improving the accuracy of diagnosis.

[0032] The connecting arm 32 is rotatably connected to the sliding seat 31. The connecting arm 32 is composed of a first connecting rod 321, a second connecting rod 322 and a support plate 324. A first rotating component 312 is provided at the end of the sliding seat 31. The first rotating component 312 is hinged to one end of the first connecting rod 321. The other end of the first connecting rod 321 is hinged to one end of the second connecting rod 322. A second rotating component 323 is provided at the other end of the second connecting rod 322. A support plate 324 is fixed to one side of the second rotating component 323. The support plate 324 is rotatably connected to the clamping portion 33. The above-mentioned hinged and rotating connection methods all adopt damping connection (in the absence of external force, the adjusted angle can be locked by the friction resistance at the connection). The first rotating component 312 is installed at the end of the sliding seat 31, allowing the first connecting rod 321 to be rotated and adjusted around the rotation center of the first rotating component 312. The first connecting rod 321 and the second connecting rod 322 are connected by a hinge, and the length of the second connecting rod 322 is greater than that of the first connecting rod 321, so that the second connecting rod 322 can swing in a wide range following the first connecting rod 321, thereby increasing the flexibility of positioning. The second rotating component 323 is fixed to the other end of the second connecting rod 322 and is connected to the support plate 324. The second rotating component 323 rotates around the rotation center of the second rotating component 323 through the support plate 324, further increasing the flexibility of adjusting the position of the ultrasonic probe 4. The first rotating component 312 and the second rotating component 323 used in this embodiment are both rotatably arranged on the sliding seat 31 and the second connecting rod 322 through bearings and bearing seats. Taking the musculoskeletal ultrasound examination of the patient's legs as an example, the patient stands in the annular track 2, with the legs kept upright and motionless. The second rotating component 323 and the annular track 2 enable the ultrasonic probe 4 to make a full circle around the patient's legs to achieve a comprehensive examination). The clamping module 3 is designed in the above manner so that the ultrasonic probe 4 can be stably fixed in the desired position, reducing the vibration and instability caused by holding the ultrasonic probe 4. The combination of multiple degrees of freedom connection methods (rotational connection and hinge) allows the ultrasonic probe 4 to be finely adjusted in multiple directions, thereby improving the accuracy of image acquisition. At the same time, the doctor can more easily adjust the position of the ultrasonic probe 4 without changing his own position or posture, which is particularly important for long-term examinations.

[0033] The circular track 2 is formed by splicing two groups of arc segments and two groups of straight segments to form a waist-shaped structure. The circular track 2 adopts a waist-shaped structural design, which can better adapt to the body shapes and examination parts of different patients, and provide a more flexible movement path of the ultrasound probe 4. Compared with the circular track, the waist-shaped structure provides patients with a larger range of activities (arm, leg extension, etc.), and enables doctors to adapt to various postures of patients, so as to more conveniently adjust the position of the ultrasound probe 4 for inspection.

[0034] The annular track 2 includes a bottom plate 21 and a top plate 22. A folded edge 211 is arranged on the top of the bottom plate 21. The folded edge 211 is provided with a threaded hole 212. The top plate 22 is provided with a through hole 221. The top plate 22 is fixed to the folded edge 211 of the bottom plate 21 by a threaded fastener 24. First, the bottom plate 21 needs to be installed, and the bottom plate 21 is fixed to the upper end of the support rod 11. Then, the sliding seat 31 of the clamping module 3 is placed on the bottom plate 21. Then, the top plate 22 is installed. The top plate 22 is fixed to the bottom plate 21 by a threaded fastener 24 (the screw passes through the through hole 221 provided on the top plate 22 and is adapted to the inner thread of the threaded hole 212 of the bottom plate 21). This ensures the stability and durability of the entire track system, simplifies the assembly and disassembly of the track, and facilitates daily maintenance and replacement when necessary.

[0035] The bottom plate 21 and the top plate 22 are both provided with two groups of guide bars 23, and the top and bottom of the sliding seat 31 are both provided with two groups of guide wheels 311. The two groups of guide bars 23 and the two groups of guide wheels 311 are used in coordination to ensure that the sliding process of the sliding seat 31 relative to the annular track 2 is more stable and accurate. By providing the guide wheels 311 at the top and bottom of the sliding seat 31, the sliding seat 31 can maintain horizontality when moving, which helps to evenly distribute the weight of the ultrasonic probe 4, reduce friction and wear caused by tilting, reduce the load at a single point, and extend the service life of the annular track 2 and the sliding seat 31.

[0036] The clamping part 33 is arranged in a "U"-shaped structure, and circular holes 331 are provided at the two open ends thereof, and locking bolts 332 are passed through the circular holes 331, and the locking bolts 332 are pressed against the open ends of the clamping part 33 through locking nuts 333. By tightening or loosening the locking nuts 333, the clamping force on the ultrasonic probe 4 can be adjusted to ensure that the ultrasonic probe 4 is stable without causing damage. By setting different opening sizes in the "U"-shaped structure, the clamping part 33 can adapt to ultrasonic probes 4 of different sizes and shapes. The clamping method of the locking bolts 332 and the locking nuts 333 makes the installation and replacement process of the ultrasonic probe 4 quick and convenient, thereby improving work efficiency.

[0037] A rubber pad is provided on the inner side of the "U"-shaped structure of the clamping portion 33. The rubber pad is in elastic contact with the outer shell of the ultrasound probe 4. The rubber pad can reduce the direct contact between the hard clamping portion 33 and the outer shell of the ultrasound probe 4 to avoid scratching or damaging the ultrasound probe 4. The ultrasound probe 4 squeezes the rubber pad and fixes it through friction and squeezing force, thereby achieving a good fixing effect, which helps to keep the image stable during musculoskeletal ultrasound.

[0038] The support plate 324 is provided with a square slot 325, through which the wire harness 41 for connecting the ultrasound probe 4 is passed. The square slot 325 provides a fixed channel for the wire harness 41 of the ultrasound probe 4, which helps to keep the wire harness 41 neat and orderly, avoids clutter, and reduces the possibility of friction between the wire harness 41 and other components, thereby reducing the loss and potential damage risk of the wire harness 41. At the same time, the neat layout of the wire harness 41 reduces the risk of tripping or pulling the wire harness 41, providing a safer environment for doctors and patients.

[0039] The support rod 11 is an electric telescopic rod, which includes an upper movable section 111 and a lower fixed section 112. The movable section 111 is fixed to the track, and the lower end of the fixed section 112 is fixed to the base of the frame 1. When examining the patient's legs, the doctor can adjust the height of the clamping module 3 through the support rod 11 to scan the legs in the vertical direction, meeting the needs of different patients and different examination parts.

[0040] A lifting chair 12 is also provided on the base of the frame 1, and the lifting chair 12 is located in the central area surrounded by the circular track 2. For some patients who are inconvenient to stand, the lifting chair 12 can support the patient so that the patient can maintain a comfortable posture during musculoskeletal ultrasound evaluation. Especially during a long examination, the lifting function of the lifting chair 12 can adjust the height of the patient's examination part, which is convenient for the doctor to accurately position the ultrasound probe 4 in the examination area. The doctor can more easily move around the patient and perform examinations at various angles without frequently adjusting the patient's position.

[0041] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
