Description

Technical Field

[0001] The present invention relates to the field of ultrasonic diagnosis assistance technology, and in particular to a musculoskeletal ultrasonic diagnosis assistance device. Background Art

[0002] As we all know, musculoskeletal is a general term for muscles and bones. Musculoskeletal includes muscle tissue and the skeletal system, which are closely connected. When muscles contract, they pull the bones to move, and abnormal or damaged bone structures may cause muscle tension or pain. Musculoskeletal ultrasound is a non-invasive project to examine muscle, bone and joint-related diseases. Musculoskeletal ultrasound uses a probe with a special frequency for ultrasound examination to understand whether there is muscle, bone and joint injury, strain or fracture; musculoskeletal ultrasound can provide auxiliary diagnostic assistance and is a non-invasive examination method.

[0003] In the field of musculoskeletal ultrasound diagnosis, accurate and clear ultrasound images are crucial for disease diagnosis. Due to the complexity and diversity of musculoskeletal structures, there are significant differences in size, shape and depth of musculoskeletal structures in different parts. However, existing traditional ultrasound diagnostic devices are usually equipped with only a single-size probe. When examining small musculoskeletal parts such as small joints (such as finger joints) and superficial tendons, large probes cannot obtain high-resolution images due to their large coverage, resulting in unclear display of fine structures. When examining large musculoskeletal parts such as thigh muscles and hip joints, small probes cannot meet the requirements of sufficient ultrasound coverage, and the probe position needs to be adjusted multiple times, and lesion information may be missed. This mismatch between the probe size and the inspection site seriously affects the accuracy and efficiency of ultrasound diagnosis, and increases the inspection time and patient discomfort.

[0004] Therefore, there is an urgent need for a musculoskeletal ultrasound diagnostic auxiliary device that can easily change the probe size according to the size of different musculoskeletal parts to improve the quality of diagnosis. Summary of the invention

[0035] Among them, a bearing 321 is arranged on the inner wall of the top side of the cavity 32, and the rotating column 34 is rotatably installed on the bearing 321; anti-slip strips are evenly arranged on the circumference of the knob 33; a plurality of placement sleeves 103 for temporarily placing probes of other specifications are also arranged on the control console 101; a through hole 324 is arranged on the inner wall of the bottom side of the cavity 32, and the positioning pin 312 movably passes through the through hole 324.

[0036] like Figure 1-6The musculoskeletal ultrasonic diagnostic auxiliary device shown in the figure can perform ultrasonic auxiliary diagnosis on the musculoskeletal parts of the patient through the probe 4, and the probes of different specifications and sizes can be replaced according to actual needs during the diagnosis process. When replacing and using: it is only necessary to use the knob 33 to rotate the rotating column 34 forward and reverse, and when the rotating column 34 rotates, it drives the worm 35 to rotate and mesh with the worm gear 36 for transmission, and then drives the screw 37 to rotate, so that the screw tube 28 can be threaded to the right on the screw 37. When the screw tube 28 moves to the right, it drives the rubber positioning head 39 to move to the right, so that the rubber positioning head 39 can be released from the positioning The locking cam 313 is pressed against the locking cam 314 and the locking cam 316 is pressed against the locking cam 314. The locking cam 313 is pressed against the locking cam 314 and the locking cam 316 is pressed against the locking cam 314. Then, the probe 4 to be replaced is taken over, and the mounting plug 41 and the conductive plug 42 on the right side of the probe 4 are inserted into the mounting groove 31. The rotating column 34 is then rotated in the opposite direction by means of the knob 33, so that the cam 313 rotates from the right side of the rotating column 34 to the left side. Subsequently, under the reset reaction of the positioning spring 316, the movable block 311 and the positioning pin 312 are moved downward, thereby causing the positioning pin 312 to move downward and be positioned in the positioning groove 43. At the same time, when the rotating column 34 rotates in the opposite direction, it also drives the worm 35 to rotate in the opposite direction and mesh with the worm wheel 36 for transmission, which can also cause the screw 37 to rotate in the opposite direction. The screw tube 38 can thereby be threadedly transmitted to the left on the screw rod 37, and the leftward movement of the screw tube 38 drives the rubber positioning head 39 to move leftward, and further the rubber positioning head 39 can be made to resist and position the positioning side plate 310. At the same time, the elastic force of the elastic spring 318 can react to make the threaded connection between the screw rod 37 and the screw tube 35 tighter and less likely to loosen the thread. In this way, the positioning of the positioning side plate 310 by the rubber positioning head 39 can further prevent the movable block 311 and the positioning pin 312 from loosening, thereby ensuring that the positioning pin 312 can be firmly positioned in the positioning groove 43.

[0037] In summary, in the present invention, the probes 4 of different sizes can be quickly disassembled and replaced conveniently and quickly, and the operation is simple and easy to replace. In this way, the disassembly and replacement can be realized only by the forward and reverse operation of the knob 33. After replacement and installation, not only can the positioning pin 312 at the bottom of the movable block 311 be urged to position the positioning groove 43 through the reaction of the positioning spring 316, but also the rubber positioning head 39 can be realized. The resistance positioning of the positioning side plate 310 can be realized, so as to further prevent the movable block 311 and the positioning pin 312 from loosening, ensure that the positioning pin 312 can be firmly positioned in the positioning groove 43, ensure that the installation positioning after replacement is more secure and not easy to loosen, so as to ensure the subsequent stable use of the probe 4. Finally, by replacing probes of different sizes, it is conducive to adapting to the use requirements of different parts of the muscles and bones in size, shape and depth, greatly improving the coverage of ultrasonic diagnosis, ensuring the accuracy and efficiency of ultrasonic diagnosis, and making the overall use effect better.
