Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an ultrasound probe device and a medical device having the same. Background Technology

[0002] Ultrasound probes are essential instruments in hospital ultrasound departments. They can be inserted into the object being observed (such as the human body) through natural openings or through small surgical incisions, allowing clinicians to use them for detection and diagnosis.

[0003] Ultrasound probe devices include various types, such as rectal probes. In practical applications, clinicians use the ultrasound probes of these devices for detection and diagnosis. If a foreign object is detected during this process, the clinician needs to remove the ultrasound probe and then switch to a cleaning device. This device uses a liquid such as water to flush away contaminants (e.g., feces and / or debris) near the foreign object, thus completing the cleaning process. After cleaning, any remaining liquid can be aspirated to facilitate subsequent diagnosis and treatment.

[0004] However, after removing the ultrasound probe, clinicians need considerable experience to predict the location and orientation of the foreign object, thus enabling accurate positioning and subsequent cleaning. Therefore, the ultrasound probe device places high demands on clinicians and requires switching between different devices, making the operation cumbersome and inefficient. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, an ultrasonic probe device is provided. The ultrasonic probe device includes an insertion part, the insertion part including a head end located at its distal end, the head end including a head end seat, a water bladder, and an ultrasonic probe, the head end seat being provided with a water bladder opening and a cleaning port, the ultrasonic probe and the water bladder being arranged around the head end seat, the water bladder enclosing the ultrasonic probe and the water bladder opening, and the cleaning port being located outside the water bladder.

[0006] For example, the cleaning port is located on the outer periphery of the headstock, and the ultrasonic probe is closer to the proximal end of the insertion part than the cleaning port.

[0007] For example, the ultrasonic probe is configured to have a marker indicating the location of the cleaning port within its ultrasonic image circumferential scanning area.

[0008] For example, the outlet of the cleaning port extends in the radial direction along the head end seat.

[0009] For example, the water bladder opening is closer to the proximal end of the insertion site than the ultrasound probe.

[0010] For example, the outer side of the head end seat is also provided with a slot that communicates with the water bladder opening, and the water bladder wraps around the slot.

[0011] For example, the head end seat is further provided with a first sealing groove and a second sealing groove spaced apart along its axial direction. The head end seat also includes a first sealing ring and a second sealing ring. One end of the water bladder is clamped between the first sealing groove and the first sealing ring sleeved on the first sealing groove, and the other end of the water bladder is clamped between the second sealing groove and the second sealing ring sleeved on the second sealing groove.

[0012] For example, the ultrasound probe device further includes a water balloon tube assembly, a cleaning tube assembly, and an operating part connected to the proximal end of the insertion part. The operating part is provided with an injection port for connecting an injection device and an aspiration port for connecting an aspiration device. One end of the water balloon tube assembly is connected to the water balloon port, and the other end of the water balloon tube assembly is connected to the injection port and the aspiration port. One end of the cleaning tube assembly is connected to the cleaning port, and the other end of the cleaning tube assembly is connected to the injection port and the aspiration port.

[0013] For example, the water bladder tube assembly includes a water bladder tube and a water bladder tube tee, one end of the water bladder tube is connected to the water bladder opening, and the water bladder tube tee is connected between the other end of the water bladder tube, the injection port and the suction port.

[0014] For example, the cleaning tube assembly includes a cleaning tube and a cleaning tube tee, one end of the cleaning tube is connected to the cleaning port, and the cleaning tube tee is connected between the other end of the cleaning tube, the liquid injection port and the suction port.

[0015] For example, the water bladder tube assembly also includes a water bladder connector, one end of which is inserted into one end of the water bladder tube, and the other end of which is bonded to the water bladder opening.

[0016] For example, the cleaning tube assembly also includes a cleaning connector, one end of which is inserted into one end of the cleaning tube, and the other end of which is bonded to the cleaning port.

[0017] According to another aspect of this utility model, a medical device is also provided. The medical device includes any of the ultrasound probe devices described above.

[0018] The ultrasound probe device provided in this embodiment allows clinicians to simultaneously clean the tissue near the foreign object when it is detected by the ultrasound probe, thereby reducing interference with imaging results. This results in more precise positioning of the foreign object, enabling more accurate cleaning. Since clinicians do not need to remove the ultrasound probe device to switch to another device, the operation is convenient and the work efficiency is high.

[0033] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0034] According to one aspect of the present invention, an ultrasonic probe device is provided. The ultrasonic probe device can be applied to any suitable medical device, including but not limited to ultrasonic probe devices. Therefore, according to another aspect of the present invention, a medical device is also provided. The ultrasonic probe device and medical device according to embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 3-5As shown, the ultrasound probe device 100 may include an insertion portion 110. The insertion portion 110 can be inserted into the body of the subject being observed. The insertion portion 110 may be a rigid tube insertion portion or a flexible tube insertion portion. The insertion portion 110 may include a distal end portion 200. For ease of description, "distal" refers to the end of the ultrasound probe device 100 closer to the subject when used by a clinician. Similarly, "proximal" as mentioned below refers to the end of the ultrasound probe device 100 closer to the clinician when used by a clinician. Typically, the distal end portion 200 is rigid. The distal end portion 200 may include a headstock 210, a water bladder (not shown), and an ultrasound probe, such as a ring array ultrasound probe 220.

[0036] The headpiece 210 can be designed into various shapes as needed. The headpiece 210 can be used to support the internal components of the headpiece 200 and can serve as a carrier for the multifunctional integration of the headpiece 200. Preferably, the headpiece 210 can be made of plastic material, which provides good insulation. The headpiece 210 can be provided with a water bladder opening 211 and a cleaning port 212. The water bladder opening 211 and the cleaning port 212 can be respectively positioned at any suitable location on the headpiece 210. The ring array ultrasonic probe 220 and the water bladder can be arranged around the headpiece 210. The water bladder and the headpiece 210 can form a liquid-filled space. The water bladder can enclose the ring array ultrasonic probe 220 and the water bladder opening 211. The ring array ultrasonic probe 220 can be mounted on the headpiece 210 by any suitable method such as welding, threaded connection, or snap-fit. In some embodiments, the headpiece 210 can also be provided with a first sealing groove 214 and a second sealing groove 215. The first sealing groove 214 and the second sealing groove 215 can be spaced apart along the axial direction of the head end seat 210. Along the axial direction of the head end seat 210, the annular array ultrasonic probe 220 and the water bladder opening 211 can be located between the first sealing groove 214 and the second sealing groove 215. The head end seat 210 may also include a first sealing ring and a second sealing ring. The first sealing ring can be fitted onto the first sealing groove 214. The second sealing ring can be fitted onto the second sealing groove 215. One end of the water bladder can be clamped between the first sealing groove 214 and the first sealing ring. The other end of the water bladder can be clamped between the second sealing groove 215 and the second sealing ring. This arrangement facilitates the connection and disassembly of the water bladder.

[0037] The annular array ultrasound probe 220 may include multiple ultrasound transducers. These multiple ultrasound transducers can be arrayed around the axis of the headstock 210, thereby forming the annular array ultrasound probe 220. The ultrasound transducers can emit and receive ultrasound waves, which can then be used to form ultrasound images. Specifically, as... Figure 2As shown, the ring array ultrasound probe 220 can emit ultrasound waves, which can be reflected by the observed object, and the ring array ultrasound probe 220 can receive ultrasound echoes. The ultrasound probe device 100 may also include a connecting portion 130. The connecting portion 130 may be disposed at the proximal end of the ultrasound probe device 100. In an embodiment where the ultrasound probe device 100 is applied to a medical device, combined with Figure 1 As shown, the medical device may further include an ultrasound host 710 and an ultrasound image display device 720. The ultrasound host 710 can be connected between the connection portion 130 of the ultrasound probe device 100 and the ultrasound image display device 720. The ring array ultrasound probe 220 can convert the received ultrasound waves into electrical signals, which can then be transmitted to the ultrasound host 710 through the connection portion 130. The ultrasound host 710 can process the electrical signals, and the processing results can be displayed on the ultrasound image display device 720. The ultrasound image display device 720 includes, but is not limited to, a display. The cleaning port 212 may be located outside the water bag.

[0038] The water bladder opening 211 can be connected to the injection device 730 and the suction device 740, respectively. Furthermore, the cleaning port 212 can be connected to both the injection device 730 and the suction device 740. The injection device 730 can be used to supply liquids such as water. Therefore, the injection device 730 may include a water supply device. The suction device 740 can be used to aspirate liquids. Therefore, the suction device 740 may include a suction pump. Based on this, combined with... Figure 1-2 As shown, the medical device may also include an injection device 730 and a suction device 740.

[0039] In practical applications, the ultrasound probe device 100 allows clinicians to insert the insertion part 110 into the body of the subject. This enables the clinician to perform detection and diagnosis using the ring array ultrasound probe 220. When a foreign body is detected, the injection device 730 provides liquid to flush the tissue near the foreign body through the cleaning port 212, facilitating cleaning and improving detection and diagnosis. After cleaning, the suction device 740 can aspirate to remove any remaining liquid through the cleaning port 212. If necessary, the injection device 730 can provide liquid through the water bladder opening 211, allowing it to enter the filling space and inflate the water bladder for better detection and diagnosis. The suction device 740 can aspirate to remove any remaining liquid through the water bladder opening 211, restoring the water bladder to its original shape.

[0040] In summary, the ultrasound probe device 100 provided in this embodiment allows clinicians to simultaneously clean the tissue near the foreign object when it is detected by the ring array ultrasound probe 220, thereby reducing interference with imaging results. This ensures more precise positioning of the foreign object by the ultrasound probe device 100, enabling more accurate cleaning. Since clinicians do not need to remove the ultrasound probe device 100 to switch to other devices, the operation is convenient and the work efficiency is high.

[0041] For example, such as Figure 4-5 As shown, compared to the annular ultrasound probe 220, the water bladder opening 211 can be closer to the proximal end of the insertion portion 110. With this configuration, the annular ultrasound probe 220 can be closer to the distal end of the insertion portion 110. Thus, when the insertion portion 110 is inserted to the same depth, the annular ultrasound probe 220, being closer to the distal end of the insertion portion 110, can detect deeper areas, allowing clinicians to perform better diagnostic and treatment procedures.

[0042] For example, such as Figure 4-5 As shown, a slot 213 is also provided on the outer side of the headstock 210. The opening of the slot 213 can face the water bladder. The slot 213 can communicate with the water bladder opening 211. The water bladder can cover the slot 213. If the slot 213 is not provided, the water bladder may block the water bladder opening 211 during suction, thus preventing the liquid in the filling space from being sucked. However, by providing the slot 213, the slot 213 can form a larger opening area with the water bladder opening 211, making it difficult for the water bladder to block this larger opening area, and the liquid in the filling space can be smoothly sucked through this larger opening area.

[0043] For example, such as Figure 4-5 As shown, the cleaning port 212 can be located on the outer periphery of the headstock 210. Compared to the cleaning port 212, the annular array ultrasound probe 220 can be closer to the proximal end of the insertion portion 110. In this way, the cleaning port 212 can be closer to the distal end of the insertion portion 110. When the insertion portion 110 is inserted to the same depth, the cleaning port 212, which is closer to the distal end of the insertion portion 110, can be used to clean deeper areas.

[0044] For example, such as Figure 9 As shown, the annular ultrasound probe 220 is configured with a marker 222 indicating the location of the cleaning port 212 within its annular ultrasound image scanning area 221. The annular ultrasound image scanning area 221 refers to the area of ​​the annular ultrasound probe 220 displayed on a component such as a monitor. The annular ultrasound image scanning area 221 can generally cover a range of 360°. The marker 222 clearly indicates the location of the cleaning port 212, allowing clinicians to perform cleaning more accurately.

[0045] For example, such as Figure 4-5 As shown, the opening of the cleaning port 212 can extend radially along the headstock 210. This arrangement results in a larger opening area for the cleaning port 212, making it less prone to blockage. Furthermore, the radial extension of the cleaning port 212 has minimal impact on the axial dimensions of the insertion portion, allowing the annular ultrasound probe 220 to be positioned closer to the distal end of the insertion portion 110. Thus, when the insertion portion 110 is inserted to the same depth, the annular ultrasound probe 220, being closer to the distal end of the insertion portion 110, can probe deeper areas, facilitating better diagnostic and treatment procedures for clinicians.

[0046] For example, such as Figure 3-6 As shown, the ultrasound probe device 100 may further include a water-filled tubing assembly 300, a cleaning tubing assembly 400, and an operating section 120. The operating section 120 can be connected to the proximal end of the insertion section 110. The operating section 120 may be provided with an injection port 510 and a suction port 520. The injection port 510 can be used to connect to an injection device 730. The suction port 520 can be used to connect to a suction device 740. The injection port 510 and the suction port 520 can be located at any suitable position on the operating section 120. The structure of the injection port 510 and the suction port 520 can be arbitrary, including but not limited to Luer interfaces. One end of the water-filled tubing assembly 300 can be connected to the water-filled tubing port 211. The other end of the water-filled tubing assembly 300 can be connected to the injection port 510 and the suction port 520. One end of the cleaning tubing assembly 400 can be connected to the cleaning port 212. The other end of the cleaning tubing assembly 400 can be connected to the injection port 510 and the suction port 520. With this configuration, the ultrasonic probe device 100 has a relatively simple structure and is easy to manufacture.

[0047] For example, such as Figure 5 As shown, the water bladder tube assembly 300 may include a water bladder tube 310 and a water bladder tube tee (not shown). In some embodiments, the water bladder tube 310 may be bonded to the head end seat 210. One end of the water bladder tube 310 may be directly or indirectly connected to the water bladder opening 211. The water bladder tube tee may be connected between the other end of the water bladder tube 310, the injection port 510, and the suction port 520. Exemplarily, the water bladder tube tee may be connected to the injection port 510 and the suction port 520 via other components (such as the injection control assembly 530 and the suction control assembly 540 described below). With this configuration, the water bladder tube assembly 300 has a simple structure and low manufacturing cost.

[0048] For example, such as Figure 5As shown, the water bladder tube assembly 300 may further include a water bladder connector 320. One end of the water bladder connector 320 can be inserted into one end of the water bladder tube 310. Exemplarily, one end of the water bladder connector 320 can be bonded to one end of the water bladder tube 310. The other end of the water bladder connector 320 can be bonded to the water bladder opening 211. Thus, the water bladder connector 320 can connect the water bladder tube 310 and the water bladder opening 211. The water bladder connector 320 includes, but is not limited to, a metal connector. With this configuration, the connection strength between the water bladder tube assembly 300 and the water bladder opening 211 is high. Exemplarily, the included angle between the water bladder connector 320 and the water bladder opening 211 can be an obtuse angle, which facilitates the passage of the cleaning brush, thereby facilitating cleaning.

[0049] For example, such as Figure 5 As shown, the cleaning tube assembly 400 may include a cleaning tube 410 and a cleaning tube tee (not shown). In some embodiments, the cleaning tube 410 may be bonded to the head end seat 210. One end of the cleaning tube 410 may be directly or indirectly connected to the cleaning port 212. The cleaning tube tee may be connected between the other end of the cleaning tube 410, the injection port 510, and the suction port 520. Exemplarily, the cleaning tube tee may be connected to the injection port 510 and the suction port 520 via other components (such as the injection control assembly 530 and the suction control assembly 540 described below). With this configuration, the cleaning tube assembly 400 has a simple structure and low manufacturing cost.

[0050] For example, such as Figure 5 As shown, the cleaning tube assembly 400 may further include a cleaning connector 420. One end of the cleaning connector 420 can be inserted into one end of the cleaning tube 410. Exemplarily, one end of the cleaning connector 420 can be bonded to one end of the cleaning tube 410. The other end of the cleaning connector 420 can be bonded to the cleaning port 212. Thus, the cleaning connector 420 can connect the cleaning tube 410 and the cleaning port 212. The cleaning connector 420 includes, but is not limited to, a metal connector. This configuration provides a high connection strength between the cleaning tube assembly 400 and the cleaning port 212.

[0051] For example, such as Figure 6-7 As shown, the operation unit 120 may also be equipped with an injection control component 530 and a suction control component 540. The injection control component 530 and the suction control component 540 may be installed at any suitable location on the operation unit 120.

[0052] The liquid injection control component 530 may include a liquid injection inlet interface 531, a liquid injection capsule interface 532, and a liquid injection cleaning interface 533. The liquid injection inlet interface 531 can be connected to the liquid injection interface 510. The liquid injection capsule interface 532 can be connected to the water bladder opening 211. Specifically, the liquid injection capsule interface 532 can be connected to a cleaning tube tee. The liquid injection cleaning interface 533 can be connected to the cleaning port 212. Specifically, the liquid injection cleaning interface 533 can be connected to a cleaning tube tee. The liquid injection control component 530 can be used to control the liquid injection inlet interface 531 to be disconnected from both the liquid injection capsule interface 532 and the liquid injection cleaning interface 533, or to control the liquid injection inlet interface 531 to be selectively connected to one of the liquid injection capsule interface 532 and the liquid injection cleaning interface 533. When the liquid injection inlet interface 531 is connected to the liquid injection capsule interface 532, liquid can enter the filling space through the water bladder opening 211. When the inlet port 531 is connected to the inlet cleaning port 533, liquid can enter the body of the observed object through the cleaning port 212. Clinicians can control the inlet control component 530 to achieve different functions.

[0053] The suction control component 540 may include a suction inlet port 541, a suction sac port 542, and a suction cleaning port 543. The suction inlet port 541 may be connected to the suction port 520. The suction sac port 542 may be connected to the water bladder opening 211. Specifically, the suction sac port 542 may be connected to a cleaning tube tee. The suction cleaning port 543 may be connected to the cleaning port 212. Specifically, the suction cleaning port 543 may be connected to a cleaning tube tee. The suction control component 540 may be used to control the suction inlet port 541 to be disconnected from both the suction sac port 542 and the suction cleaning port 543, or to control the suction inlet port 541 to be selectively connected to either the suction sac port 542 or the suction cleaning port 543. When the suction inlet port 541 is connected to the suction sac port 542, liquid in the filling space can be drawn out through the water bladder opening 211. When the suction inlet 541 is connected to the suction cleaning outlet 543, fluid within the observed object can be suctioned out through the cleaning port 212. Clinicians can control the suction control component 540 to achieve different functions.

[0054] For example, each of the injection control assembly 530 and the suction control assembly 540 may include a valve seat 610 and a valve body 620. Figure 8Taking the suction control assembly 540 as an example, the specific structure of the valve seat 610 and valve body 620 is shown. The injection control assembly 530 can also adopt a similar structure, and for simplicity, it will not be described separately. The valve seat 610 can be mounted on the operating part 120. The valve body 620 can be movably mounted on the valve seat 610 by means of translation or rotation. The suction inlet port 541, the suction water sac port 542, and the suction cleaning port 543 can all be mounted on the valve seat 610. The suction inlet port 541 can be connected to the suction port 520 via a connecting pipe 560. A channel 621 can be provided on the valve body 620. One end 622 of the channel 621 can always be connected to the suction inlet port 541. The other end 623 of the channel 621 can be blocked by the valve seat 610 by the movement of the valve body 620 relative to the valve seat 610, or connected to the suction water sac port 542 or the suction cleaning port 543. When the other end 623 of channel 621 is blocked by valve seat 610, the suction inlet port 541 is not connected to either the suction sump port 542 or the suction cleaning port 543. When the other end 623 of channel 621 is connected to the suction sump port 542, the suction inlet port 541 can communicate with the suction sump port 542. When the other end 623 of channel 621 is connected to the suction cleaning port 543, the suction inlet port 541 can communicate with the suction cleaning port 543.

[0055] For example, such as Figure 8 As shown, the valve body 620 is movably connected to the valve seat 610 along the straight direction PP. Compared to other methods, the structure of the valve body 620 and valve seat 610 can be relatively simple.

[0056] For example, such as Figure 8As shown, a first abutment 630 and a second abutment 640 can be connected to the outer periphery of the valve seat 610. A channel 621 can be disposed at one end of the valve body 620. A button 650 can be connected to the other end of the valve body 620. The button 650 can be located outside the valve seat 610. Along the linear direction PP, the first abutment 630 can be located between the button 650 and the second abutment 640. For each of the injection control assembly 530 and the suction control assembly 540, it may further include a first elastic element 660 and a second elastic element 670. The first elastic element 660 can be connected between the button 650 and the first abutment 630. The first elastic element 660 includes, but is not limited to, an elastic element made of elastic material such as a spring or rubber. The second elastic element 670 can be connected between the first abutment 630 and the second abutment 640. The second elastic element 670 includes, but is not limited to, an elastic element made of elastic material such as a spring or rubber. The elastic modulus of the first elastic element 660 can be less than the elastic modulus of the second elastic element 670. The clinician can press button 650, causing valve body 620 to move in a straight line PP, thereby connecting the other end 623 of channel 621 to suction cleaning port 543. At this time, the first elastic element 660 can be compressed. Then, the clinician can increase the force of pressing button 650, causing valve body 620 to continue moving in a straight line PP, thereby connecting the other end 623 of channel 621 to suction sac port 542. At this time, the second elastic element 670 can be compressed. When the clinician releases the pressure of button 650, the second elastic element 670 and the first elastic element 660 can release their elastic potential energy, thereby allowing button 650 to return to its initial position. Thus, the injection control assembly 530 and the suction control assembly 540 can be two-stage control assemblies, which are convenient for clinicians to operate.

[0057] For example, the buttons of the infusion control assembly 530 and the suction control assembly 540 may have different structures (e.g., size and / or shape). This serves as a foolproof mechanism to prevent clinicians from misusing the device.

[0058] For example, such as Figure 8 As shown, a first groove 651 may be provided on the button 650. One end of the first elastic member 660 can be inserted into the first groove 651. With this configuration, the button 650 has a better positioning effect on the first elastic member 660.

[0059] For example, such as Figure 8 As shown, a second groove 631 may be provided on the first abutment 630. The other end of the first elastic member 660 can be inserted into the second groove 631. With this configuration, the first abutment 630 provides better positioning for the first elastic member 660.

[0060] For example, such as Figure 8As shown, a third groove 632 may be provided on the first abutment 630. One end of the second elastic member 670 can be inserted into the third groove 632. With this arrangement, the first abutment 630 provides better positioning for the second elastic member 670.

[0061] For example, such as Figure 8 As shown, a fourth groove 641 may be provided on the second abutment 640. The other end of the second elastic member 670 may be inserted into the fourth groove 641. With this configuration, the second abutment 640 provides better positioning for the second elastic member 670.

[0062] For example, such as Figure 8 As shown, when button 650 abuts against the first abutment 630, the other end 623 of channel 621 can be connected to one of the suction sac interface 542 and the suction cleaning interface 543. When the first abutment 630 abuts against the second abutment 640, the other end 623 of channel 621 can be connected to the other of the suction sac interface 542 and the suction cleaning interface 543. In the embodiment shown in the figure, when button 650 abuts against the first abutment 630, the other end 623 of channel 621 can be connected to the suction cleaning interface 543. When the first abutment 630 abuts against the second abutment 640, the other end 623 of channel 621 can be connected to the suction sac interface 542. When button 650 abuts against the first abutment 630, and when the first abutment 630 abuts against the second abutment 640, the clinician can receive tactile feedback during the abutment, thereby confirming that the other end 623 of channel 621 is connected to the suction sac interface 542 or the suction cleaning interface 543.

[0063] For example, such as Figure 8 As shown, the first elastic element 660 can be arranged around the valve body 620. One end of the second elastic element 670 can be arranged around the first elastic element 660. With this arrangement, the structure of the injection control assembly 530 and the suction control assembly 540 is more compact.

[0064] For example, such as Figure 6 As shown, the operation unit 120 may also be equipped with functional components 550. The number of functional components 550 can be arbitrary, such as one, two, or more. Clinicians can control the functional components 550, thereby enabling remote control of the ultrasound host 710 and other functions. Clinicians can customize the functions of the functional components 550, such as setting mode switching, gain amplification, screenshot, and other functions.
