Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of ultrasonic probes, and in particular to an adjustable cardiac ultrasonic probe. Background Art
[0002] A cardiac ultrasound probe is a medical device designed specifically for performing cardiac ultrasound examinations (i.e., echocardiograms), which generates images of the heart by emitting and receiving ultrasound waves. This probe allows doctors to observe cardiac structures such as the size and function of the ventricles and atria, the status of the valves, and blood flow, thereby helping to diagnose a variety of heart diseases. Cardiac ultrasound probes usually have a high frequency range to provide detailed image quality and may have adjustable angles or curvatures to accommodate different patient anatomy to ensure optimal imaging. In addition, these probes are designed with ease of operation and comfort in mind, making it easier to operate for long periods of time.
[0003] During ultrasound examinations, in order to obtain clearer images and accurate diagnostic results, patients are usually asked to lie on the examination bed, while medical staff will use the ultrasound probe to gently slide over the body part that needs to be examined. For patients with wider bodies or specific body positions, there may indeed be some challenges, such as limited operating space. To solve these problems, modern ultrasound equipment is often equipped with probes of various lengths and shapes to accommodate different examination needs and personal body shapes.
[0004] It can be seen that equipping probes of various lengths can solve the adaptability problem to a certain extent. However, in order to adapt to different examination needs, doctors may need to frequently change probes of different lengths, which not only increases the complexity of the operation, but may also cause workflow interruptions and affect efficiency. At the same time, multiple probes mean more storage space requirements, and each probe needs to be managed and maintained separately, increasing the logistical burden. Due to the inconvenience caused by frequent probe replacement, it is inconvenient for medical staff to adjust the length or angle of the probe in real time as needed during the examination, and it is not convenient to adapt to patients of different body shapes with one probe, which reduces work efficiency.
[0005] In view of this, the present invention provides an adjustable cardiac ultrasound probe. Summary of the invention
[0006] The object of the present invention is to provide an adjustable cardiac ultrasound probe to solve the problems raised in the above background technology.

The telescopic part is used to adjust the detection length of the adjusting part, which is convenient for medical staff to operate with one hand. When the length between the adjusting part and the telescopic part becomes longer, the stabilizing part is driven to press down to improve the supporting effect of the probe body as a whole, thereby reducing the operating burden. Moreover, when the probe body moves as a whole, the stabilizing part applies the gel to the skin while providing supporting force.
[0008] As a further improvement of the present technical solution, the telescopic part includes a guide rod, which is movably connected to the inner wall of the handle, and a long groove is provided on the outer wall of the guide rod.

[0012] As a further improvement of the technical solution, the acoustic lens is in a hemispherical concave shape, and the acoustic lens is used to focus the ultrasonic beam. The acoustic lens can rotate on the skin along its spherical arc surface to adjust the focusing angle of the ultrasonic beam.
[0013] As a further improvement of the technical solution, the balloon is a hollow rubber sphere, the interior of the balloon is filled with gas, the balloon is used to be squeezed at the opening of the acoustic lens, and the balloon is used to maintain the sealing effect between the acoustic lens and the guide rod.
[0014] As a further improvement of the present technical solution, the stabilizing member includes a suction cup, which is fixedly connected to one end of the guide rod, and the balloon and the acoustic lens are both located inside the suction cup, and a plurality of rollers are movably connected inside the suction cup via a rotating shaft.

[0017] 2. In the adjustable cardiac ultrasound probe, as the length between the adjusting part and the telescopic part increases, the stabilizing part will be pressed down to provide additional support force; this not only enhances the overall stability of the probe body, but also reduces the operating burden of medical staff, and ensures that even at a longer working distance, the probe can still fit the patient's skin firmly and ensure image quality; In addition, during the overall movement of the probe, the stabilizer can also help spread the gel on the skin, reducing the time and steps of manual application of gel and improving inspection efficiency; at the same time, the distribution of gel helps to improve the transmission effect of ultrasound and further optimize the imaging quality.

[0020] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] Example 1, please refer to Figure 1-Figure 7 As shown, the purpose of this embodiment is to provide an adjustable cardiac ultrasound probe, including a probe body 13, a cable 12 is provided at the end of the probe body 13, an ultrasound detector 1 is provided at the other end of the cable 12, a clamp 11 is fixedly connected to the outer wall of one side of the ultrasound detector 1, and the probe body 13 is movably connected inside the clamp 11; The probe body 13 includes a handle 130, a telescopic member 131 is provided inside the handle 130, a balloon 132 and a stabilizing member 134 are fixedly connected to the end of the telescopic member 131, the balloon 132 is located inside the stabilizing member 134, an adjusting member 133 is provided inside the telescopic member 131, and the adjusting member 133 is located between the inside of the stabilizing member 134 and the outer wall of the balloon 132; The adjusting member 133 is used for ultrasonic detection and can adjust the angle of ultrasonic detection. The telescopic member 131 is used to adjust the detection length of the adjusting member 133, which is convenient for medical staff to operate with one hand. When the length between the adjusting member 133 and the telescopic member 131 becomes longer, the stabilizing member 134 is driven to press down to improve the supporting effect of the probe body 13 as a whole, thereby reducing the operating burden. Moreover, when the probe body 13 moves as a whole, the stabilizing member 134 applies the gel to the skin while providing supporting force. First, the specific structure of the telescopic member 131 is disclosed. The telescopic member 131 includes a guide rod 1310, which is movably connected to the inner wall of the handle 130. A long groove is provided on the outer wall of the guide rod 1310. A rack 1311 is fixedly connected inside the long groove of the guide rod 1310. A gear 1312 is meshed and connected on the teeth of the rack 1311. The gear 1312 is movably connected inside the handle 130. The gear 1312 and the handle 130 are connected through a rotating shaft. A balloon 132 and a stabilizing member 134 are fixedly connected to one end of the guide rod 1310. An adjusting member 133 is provided between the outer wall of the balloon 132 and the inside of the guide rod 1310. The outer wall of the guide rod 1310 is fixedly connected to the cable 12 near the other end. See also Figure 5-Figure 8 As shown, the thumb holding the handle 130 continuously slides on the surface of the gear 1312 (while the other four fingers keep holding), thereby driving the gear 1312 to rotate inside the handle 130, and the gear 1312 rotates and engages to drive the rack 1311 to move up and down, so that the rack 1311 drives the guide rod 1310 to be able to be telescopically adjusted inside the handle 130, and the detectable length of the adjustment member 133 is adjusted, so that the working length of the probe can be flexibly adjusted according to the patient's body shape and examination requirements, ensuring that when facing patients with wider bodies or specific body positions, the arm length of medical staff will not become a limiting factor; Wherein, an intelligent two-way clutch is provided on the rotating shaft of the gear 1312. When the medical staff holds the handle 130 and the thumb is ready to slide on the surface of the gear 1312, the intelligent two-way clutch is set to a default working mode (for example, allowing counterclockwise rotation); when the thumb slides on the surface of the gear 1312, if a counterclockwise force is applied, the gear 1312 will drive the rack 1311 to move downward, thereby extending the guide rod 1310; if reverse adjustment is required (i.e. shortening the guide rod 1310), an instruction can be sent to the intelligent two-way clutch through the control system; when the control system receives the instruction to switch direction, it activates the electromagnetic actuator and adjusts the internal structure of the clutch so that the gear 1312 can now only rotate in the clockwise direction; at this time, when the thumb slides on the surface of the gear 1312 again, it will cause the rack 1311 to move upward, thereby shortening the guide rod 1310; In addition, in order to facilitate holding the handle 130 with one hand, a plurality of arc-shaped grooves are provided on the outer wall of the handle 130 opposite to the gear 1312, and memory foam 1300 is provided inside the plurality of arc-shaped grooves of the handle 130, and the memory foam 1300 is used to increase the comfort and friction of holding the handle 130; See also Figure 7 As shown, the memory foam 1300 is embedded in a plurality of arc-shaped grooves of the grip 130. The design of the arc-shaped grooves allows the fingers to be placed on the grip 130 more naturally, reducing the fatigue caused by long-term gripping. The working principle of the memory foam 1300 is known to those skilled in the art. The memory foam 1300 is made of polyurethane foam. This material contains an open cell structure, and each cell can be deformed according to the applied pressure. When the fingers grip the grip 130, the memory foam 1300 will feel the pressure applied by the fingers and gradually adapt to the shape of the fingers. In the absence of external force, the memory foam 1300 will maintain its original shape. It can be adjusted according to the specific shape of each user's fingers, providing a personalized fitting experience, and greatly improving the comfort of gripping. At the same time, the memory foam 1300 also has a certain temperature sensitivity, which means that it will adjust its hardness according to the temperature change of the contact surface; when the temperature of human skin is higher than the ambient temperature, the memory foam 1300 will become slightly softer when it touches the fingers, further enhancing its fit and comfort; and the memory foam 1300 also has a certain viscosity, which increases the contact area between the fingers and the handle 130, improves friction and prevents sliding; even when the fingers are sweaty or there is gel, the memory foam 1300 can still provide a good grip to ensure the safety and stability of the operation.
[0022] Secondly, the specific structure of the adjustment member 133 is disclosed. The adjustment member 133 includes an acoustic lens 1330, which is clamped and connected to the outer wall of the balloon 132. A support rod 1331 is fixedly connected inside the acoustic lens 1330, and a stretch rod 1332 is slidably connected inside the support rod 1331. A push block 1333 is fixedly connected to the end of the stretch rod 1332. The support rod 1331 and the stretch rod 1332 are both located between the balloon 132 and the inside of the guide rod 1310. The acoustic lens 1330 is a hemispherical concave shape. The acoustic lens 1330 is used to focus the ultrasonic beam. The acoustic lens 1330 can rotate on the skin along its spherical arc surface to adjust the focusing angle of the ultrasonic beam. See also Figure 7 , Fig. 9 and Fig.10 As shown, by holding the handle 130 with one hand, and placing the thumb upright on the surface of the push block 1333 (while the other four fingers keep holding), the push block 1333 is pushed to drive the extension rod 1332 and the support rod 1331 to tilt inside the guide rod 1310, and drive the acoustic lens 1330 on the balloon 132 to move in the opposite direction of the push block 1333; because the acoustic lens 1330 is a hemispherical concave surface, when the acoustic lens 1330 is pushed, it can rotate on the skin along its spherical arc surface to adjust the focusing angle of the ultrasonic beam; In order to prevent the acoustic lens 1330 from being damaged by gel entering the acoustic lens 1330 during detection, the balloon 132 is a hollow rubber sphere filled with gas. The balloon 132 is used to squeeze the opening of the acoustic lens 1330 to maintain the sealing effect between the acoustic lens 1330 and the guide rod 1310. The balloon 132 has good elasticity and deformability due to the rubber, so that the balloon 132 can change its shape and fit closely to the contact surface when squeezed; and, since the balloon 132 has a certain expansion pressure when filled with gas, when the balloon 132 is placed at the opening of the acoustic lens 1330, the gas pressure in the balloon 132 will push the surface of the balloon 132 to fit closely to the contact surface of the acoustic lens 1330; at the same time, according to the softness and elasticity of rubber, when the acoustic lens 1330 is adjusted and changed in angle, the balloon 132 can compensate for these changes through its own elastic deformation, so that the balloon 132 is always squeezed at the opening of the acoustic lens 1330, ensuring continuous sealing performance and preventing the gel from leaking from the gap between the acoustic lens 1330 and the guide rod 1310; At the same time, when the length of the guide rod 1310 and the handle 130 is adjusted, the movement of the guide rod 1310 will drive the balloon 132 to move, and the balloon 132 will drive the acoustic lens 1330 to move; Figure 5 and Figure 6As shown, the size of the push block 1333 is larger than the size of the center hole of the guide rod 1310, and the push block 1333 is connected to the acoustic lens 1330 through the support rod 1331 and the extension rod 1332. Therefore, when the acoustic lens 1330 moves with the guide rod 1310 and the balloon 132, the support rod 1331 will be driven to move synchronously. At this time, the push block 1333 and the extension rod 1332 remain stationary, so that the support rod 1331 and the extension rod 1332 are extended and retracted, thereby adjusting the detection length of the acoustic lens 1330.
[0023] Finally, the specific structure of the stabilizing member 134 is disclosed. The stabilizing member 134 includes a suction cup 1340, which is fixedly connected to one end of the guide rod 1310. The balloon 132 and the acoustic lens 1330 are both located inside the suction cup 1340. A plurality of rollers 1341 are movably connected to the suction cup 1340 through a rotating shaft. The suction cup 1340 is conical in shape as a whole, and is made of silicone. The plurality of rollers 1341 are evenly distributed on the edge of the contact surface of the suction cup 1340, and the rollers 1341 are made of medical-grade plastic. See also Figure 5 and Fig.11 As shown, as the length between the guide rod 1310 and the handle 130 is extended, the suction cup 1340 at the end thereof is pressed downward, so that the suction cup 1340 is adsorbed on the patient's skin surface according to its structural material characteristics, thereby enhancing the overall stability of the probe body 13, reducing the burden on the medical staff's arms, and ensuring that the probe can still firmly fit the patient's skin even at a longer working distance, thereby ensuring image quality; Furthermore, when the probe body 13 moves as a whole to find the detection position, the suction cup 1340 will move on the patient's skin surface, driving the multiple rollers 1341 inside it to rotate on the skin to apply the gel on the skin, thereby reducing the time and steps of manually applying the gel and improving the inspection efficiency; Among them, the suction cup 1340 is made of silicone material with good elasticity and biocompatibility, so that it can not only ensure good fit with the skin, but also avoid causing allergic reactions or other discomforts; and the roller 1341 is made of medical-grade plastic material, so that it will not damage the skin and can effectively roll on the skin surface; ensuring the stable adsorption of the suction cup 1340 on the skin, and when necessary, it can also drive the roller 1341 to complete the application of the gel through simple moving actions, which greatly improves the operating efficiency and patient comfort.
[0024] The improvement of this embodiment is that: the medical staff can hold the handle 130 with one hand and easily place the end of the adjustment member 133 on the patient's skin surface for ultrasonic testing; by extending the thumb downward and pushing the top of the adjustment member 133 (while the other four fingers remain in the grip state), the detection angle can be adjusted instantly; this design avoids the need to change the hand-holding posture or use the other hand for assistance, greatly improves the convenience and flexibility of operation, and is particularly suitable for inspection environments that require rapid response and frequent adjustments; When the thumb slides the telescopic member 131 on the outer wall of the handle 130, the length between the telescopic member 131 and the handle 130 can be conveniently adjusted; this telescopic function can flexibly adjust the working length of the probe according to the patient's body shape and examination requirements, ensuring that when facing patients with wider bodies or specific body positions, the arm length of medical staff will not become a limiting factor; this operation can still achieve precise adjustment of the length through simple one-handed operation, adapting to various clinical situations, without the need to switch back and forth between multiple probes of different lengths, reducing the time and complexity of preparation work; As the length between the adjusting member 133 and the telescopic member 131 increases, the built-in stabilizing member 134 will automatically press down to provide additional support force; this not only enhances the overall stability of the probe body 13 and reduces the operating burden of medical staff, but also ensures that the probe can still firmly fit the patient's skin even at a longer working distance to ensure image quality; During the overall movement of the probe, the stabilizer 134 can not only provide the necessary support force, but also help to spread the gel on the skin, reducing the time and steps of manually applying the gel and improving the inspection efficiency; at the same time, improving the distribution of the gel helps to improve the transmission effect of ultrasound and further optimize the imaging quality.
[0025] In summary, the working principle of this scheme is as follows: First, the medical staff operates by holding the handle 130 with one hand, with the thumb placed upright on the surface of the push block 1333, and the other four fingers remain in a holding state; the handle 130 is specially designed with an arc-shaped groove, which allows the fingers to be placed on it in a more natural posture, thereby effectively reducing the fatigue caused by long-term holding; When the fingers hold the handle 130, the memory foam 1300 inside the handle 130 starts to work; the memory foam 1300 can keenly sense the pressure applied by the fingers, and gradually change its shape according to the pressure to adapt to the specific contour of the fingers, and when the external force disappears, it will return to its original shape; in this way, it can provide a personalized fit experience for the fingers of different users, greatly improving the comfort of holding; In addition, the memory foam 1300 is also sensitive to temperature. When the human skin temperature is higher than the ambient temperature, it will become slightly softer when in contact with the fingers, further enhancing the fit with the fingers and making the user feel more comfortable. At the same time, the memory foam 1300 itself has a certain viscosity, which can increase the contact area between the fingers and the handle 130, thereby increasing the friction between the two and effectively preventing slippage during operation. Even when the fingers are sweaty or gel is present, the memory foam 1300 can still provide reliable grip to ensure the safety and stability of the entire operation process. When the push block 1333 is pushed, the extension rod 1332 and the support rod 1331 are tilted inside the guide rod 1310, so that the acoustic lens 1330 moves on the balloon 132 in the opposite direction to the push block 1333; since the acoustic lens 1330 is in a hemispherical concave shape, when it is pushed, it can flexibly rotate on the skin along its own spherical arc surface, and through such rotation, the focusing angle of the ultrasonic beam can be effectively adjusted; In this process, the balloon 132 plays an important role in sealing and protecting. The balloon 132 is made of rubber. With good elasticity and deformability of rubber, it can easily change its shape when squeezed, so as to fit closely to the contact surface. In addition, the balloon 132 is filled with gas, which will generate a certain expansion pressure. When it is placed at the opening of the acoustic lens 1330, the internal gas pressure will push its surface to fit closely to the contact surface of the acoustic lens 1330. At the same time, based on the soft and elastic characteristics of rubber, when the acoustic lens 1330 is adjusted in angle or changes in shape, the balloon 132 can rely on its own elastic deformation to compensate for these changes, and always be tightly squeezed at the opening of the acoustic lens 1330, ensuring continuous and stable sealing performance, and effectively preventing the gel from entering the interior of the acoustic lens 1330 from the gap between the acoustic lens 1330 and the guide rod 1310, thereby avoiding damage to the acoustic lens 1330. When the medical staff holds the handle 130 and is ready to slide the thumb on the surface of the gear 1312, the intelligent two-way clutch is pre-set to a default working mode (for example, set to allow counterclockwise rotation); when the thumb continues to slide on the surface of the gear 1312 (the other four fingers remain in the grip state unchanged), the gear 1312 will rotate inside the handle 130; If a counterclockwise force is applied at this time, the gear 1312 will drive the rack 1311 to move downward, thereby causing the guide rod 1310 to extend; if reverse adjustment is required, that is, shortening the guide rod 1310, a corresponding instruction can be sent to the intelligent two-way clutch through the control system; after receiving the instruction to switch direction, the control system will activate the electromagnetic actuator to adjust the internal structure of the clutch so that the gear 1312 can only rotate in the clockwise direction; at this time, the thumb slides on the surface of the gear 1312 again, which will cause the rack 1311 to move upward, thereby shortening the guide rod 1310; During the process of adjusting the length of the guide rod 1310 and the handle 130, the movement of the guide rod 1310 will drive the balloon 132 to move synchronously, and the movement of the balloon 132 will drive the acoustic lens 1330 to move accordingly, and at the same time, it will also drive the support rod 1331 to move synchronously, while the push block 1333 and the extension rod 1332 remain relatively static, so that the support rod 1331 and the extension rod 1332 can be telescoped, thereby realizing flexible adjustment of the detection length of the acoustic lens 1330; through such an adjustment mechanism, the acoustic lens 1330 can conveniently adjust the working length of the probe according to the patient's body shape and specific examination needs, ensuring that when facing patients with a wider body shape or in a specific body position, the arm length of the medical staff will not limit the operation; As the length between the guide rod 1310 and the handle 130 increases, the suction cup 1340 at the end of the guide rod 1310 is pressed downward. Relying on its own structural material characteristics, the suction cup 1340 can be firmly adsorbed on the patient's skin surface, which not only enhances the overall stability of the probe body 13 and reduces the burden on the medical staff's arms, but also ensures that even at a longer working distance, the probe can still be firmly attached to the patient's skin surface, thereby ensuring that the quality of the acquired image is not affected; In addition, when the probe body 13 moves as a whole to find the detection position, the suction cup 1340 will move along with it on the patient's skin surface. During this process, multiple rollers 1341 inside the suction cup 1340 will rotate on the skin. The rotation of the rollers 1341 can help spread the gel on the skin, thereby reducing the time and operation steps required for manual application of the gel, and effectively improving the overall efficiency of the inspection.
