Description

Technical Field

[0001] The present invention relates to the field of musculoskeletal ultrasound, and more particularly to a probe assembly of a self-filling ultrasonic coupling agent for musculoskeletal ultrasound. Background Art

[0002] Ultrasonic coupling agent can fill the air gap between the skin and the probe, reduce the acoustic impedance difference, and allow ultrasound to enter the human body better, which is convenient for later imaging. It is an essential auxiliary consumable in ultrasound examination. The coupling agent can eliminate the air between the ultrasound probe and the skin, because air has a significant obstruction to the propagation of ultrasound. The acoustic impedance of the coupling agent is similar to that of the skin, which allows ultrasound energy to enter the human body to the maximum extent and effectively transmit the echo in the body back to the probe, thereby significantly improving the quality of the image;

[0003] However, a solid coupling patch is laid on the surface of the inspection position to fill the gap between the probe and the body surface, but when in use, the solid coupling patch needs to be moved as the inspection position moves, which is troublesome to use. When the solid coupling patch is moved by hand, the solid coupling patch will be contaminated. There is also a solution in the prior art to fix the solid coupling patch on the probe through a connector, but because different probes have different models and the assembly difference between the solid coupling patch and the probe, the solid coupling patch cannot form a good fit with the probe, and the expected solid coupling effect cannot be achieved.

[0004] Based on the above technical problems, the prior art also provides some solutions. For example, the Chinese patent with the authorization announcement number CN109091166A discloses an ultrasonic probe coupling assembly and an ultrasonic probe assembly. The ultrasonic probe ferrule assembly can be adapted to convex array probes with different curvatures while fixing the solid coupling member on the ultrasonic probe. It can also eliminate the assembly differences between the ultrasonic probe, including the convex array probe and the linear array probe, and the ultrasonic probe ferrule and the processing differences of the ultrasonic probe ferrule assembly, so that the solid coupling member and the ultrasonic probe have a better fitting effect, and there is no need to use a gel coupling agent. The solid coupling member used can form a good fit with the ultrasonic probe.

[0005] However, in the prior art of ultrasonic examination of muscles and bones, it is usually necessary to adjust the force applied to the ultrasonic probe when searching for the specific injury location, so as to change the depth of the probe to find the injury sites at different depths. This process is time-consuming, and often the amount of ultrasonic coupling agent applied once is not enough, so it is necessary to apply the ultrasonic coupling agent again midway. However, since muscle and bone injuries are sometimes relatively hidden, the position of the probe requires to be more precise. When applying the coupling agent again midway, it is necessary to lift the probe and then place the probe again after application. At this time, the position of the probe has changed, and repeated positioning is required, which wastes diagnosis and treatment time and reduces diagnosis and treatment efficiency. Summary of the invention

[0006] In view of the problem that in the prior art, when searching for a specific injury location, it is necessary to adjust the force applied to the ultrasonic probe to achieve a change in the depth of the probe to find injury sites at different depths, this process is time-consuming, and often the amount of ultrasonic coupling agent applied once is not enough, and it is necessary to apply the ultrasonic coupling agent again midway. However, since musculoskeletal injuries are sometimes relatively hidden, the position of the probe requires to be relatively precise, and the probe needs to be lifted when the coupling agent is applied again midway, and then placed again after application.

[0021] When the motor body drives the active gear disc to rotate, the rotating active gear disc will synchronously drive the transmission rod to rotate, and the rotating transmission rod will enter the storage box along the inner side of the connecting hole. The transmission rod rotating in the storage box will drive multiple side stirring rods to rotate.

[0022] By increasing the temperature of the coupling agent, the irritation and discomfort caused by applying the coupling agent to the patient's skin surface can be reduced, and the patient's tension can be relieved. The heated coupling agent can fill the tiny gap between the probe and the skin, reduce the interference of air on the transmission of sound waves, and improve the clarity and accuracy of the image.

[0054] like Figure 6 As shown, one side of the bottom sealing disc 502 is fixedly connected to a side supporting plate 501 , and one side of the side supporting plate 501 is fixedly connected to one side of the ultrasonic body 2 .

[0055] The upper and lower sides of the material guiding roller 505 are blocked by a top sealing plate 508 and a bottom sealing plate 502 respectively to prevent the coupling agent from leaking out.

During the mixing process, since the bottom stirring rod 509 and the extension plate 5010 at the bottom of the top sealing plate 508 are fixedly arranged on the inner side of the material guide roller 505, when the material guide roller 505 rotates to drive the coupling agent to rotate, the coupling agent is stirred by the bottom stirring rod 509 and the extension plate 5010, which can improve the fluidity of the coupling agent, so that the coupling agent can be more smoothly filled in the gap between the probe and the skin, and the uniformity of the coupling agent is improved, thereby improving the effect of subsequent ultrasonic detection using the ultrasonic head 3;

The transmission rod 5015 rotating in the material storage box 402 will drive multiple side stirring rods 5017 to rotate. The rotating side stirring rods 5017 can stir the coupling agent accumulated in the material storage box 402, and can stir the coupling agent in advance to reduce the stratification or precipitation of the coupling agent.

[0068] After the controller body 602 is started at the same time, the controller body 602 drives the heater body 604 to work, and the heater body 604 is fixedly limited on one side of the side fixing plate 601 by the side limiting plate 603. After the heater body 604 is started, it can heat along one side of the side heat conducting plate 605 through the heater body 604, and continue to heat up the side heat conducting plate 605. After the temperature of the side heat conducting plate 605 continues to rise, the temperature will be conducted to one side of the arc-shaped heat conducting plate 607 along the heat conducting metal frame 606. The arc-shaped heat conducting plate 607 can conduct the temperature to the surface of the material guide roller 505, and heat up the coupling agent in the material guide roller 505. At the same time, the rotating material guide roller 505 can keep the temperature of the coupling agent evenly increased. By increasing the temperature of the coupling agent, the irritation and discomfort caused by the coupling agent being applied to the patient's skin surface can be reduced, and the patient's tension can be relieved. The heated coupling agent can fill the tiny gap between the probe and the skin, reduce the interference of air on the transmission of sound waves, and improve the clarity and accuracy of the image.
