Description

Technical Field

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

[0002] With advancements in medical technology, ultrasound-assisted therapy is increasingly being used in clinical diagnosis and treatment. Currently, during ultrasound-assisted therapy, an ultrasound probe is inserted into the patient to examine lesions. The ultrasound core within the probe is typically designed to rotate, allowing for three-dimensional imaging through rotational scanning. To prevent direct contact between the ultrasound core and the patient during rotation, an acoustic window housing usually surrounds the ultrasound core within the probe. Since ultrasound waves produce echoes of varying intensity when passing through different acoustic interfaces—meaning ultrasound waves can barely propagate from liquid to gas—the space enclosed by the acoustic window housing is usually filled with oil. This allows the ultrasound core to rotate within the oil during use, enabling the ultrasound waves to propagate normally.

[0003] However, in existing ultrasonic probes, even when the space enclosed by the acoustic window housing is filled with oil, air bubbles easily form within the oil. These air bubbles result in a loss of ultrasonic signal, significantly impacting the imaging quality of the ultrasonic probe. Therefore, there is an urgent need for an ultrasonic probe that is less prone to air bubble formation. Utility Model Content

[0004] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, an ultrasonic probe is provided. The ultrasonic probe includes a base, a first housing, a second housing, and at least two oil pipes. The first housing is connected to a first side of the base and forms a first cavity with the base. An ultrasonic core is disposed within the first cavity. The second housing is connected to a second side of the base and forms a second cavity with the base. The oil pipes pass through the second cavity and communicate with the first cavity. The oil pipes have a connecting portion and an extension portion. The connecting portion is connected to the base, and the extension portion extends out of the second cavity.

[0005] The ultrasonic probe provided by this invention, during installation, allows the second housing to be connected to the base, thereby positioning the first housing and connecting it to the base. Oil can then be injected into the first cavity via the extended portion of the oil pipe. This injection can be performed from outside the second cavity, eliminating the need to disassemble the second housing. This avoids the sealing failure between the first housing and the base caused by repeated disassembly and reassembly of the second housing, and consequently, prevents air bubbles from forming within the first cavity due to a failed seal. This type of ultrasonic probe is less prone to air bubble formation in the first cavity, resulting in better imaging of the ultrasonic core.

[0006] For example, the oil pipe has a first port and a second port. The first port is located at the end of the extension portion away from the base, and the second port is located at the end of the connection portion away from the first port. The oil pipe is connected to the first cavity through the second port. The first port of one of the at least two oil pipes forms an oil inlet for oil to enter, and the first port of the other of the at least two oil pipes forms an outlet for gas to exit.

[0007] For example, a connector is provided at one end of the connecting part near the base. The connector is threaded to the base. The connector is hollow inside and forms a first channel. The oil pipe is connected to the first cavity through the first channel.

[0008] For example, a second channel is provided on the base, a connector is threaded to the second channel, and an oil pipe is connected to the first cavity through the first channel and the second channel in sequence.

[0009] For example, the length of the extension portion in the axial direction is 35mm to 45mm.

[0010] For example, the tubing includes sections made of a flexible material.

[0011] For example, at least a portion of the oil pipe is flattened.

[0012] For example, a seal is detachably provided on the end of the extension portion away from the base.

[0013] For example, a mounting plate is provided in the second cavity, the mounting plate is connected to the second housing and a clearance gap is formed between the mounting plate and the second housing, and the extended portion passes through the clearance gap.

[0014] For example, the connection between the first housing and the base has a contact thickness of 0.5 mm to 0.6 mm.

Detailed Implementation

[0027] 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.

[0028] According to one aspect of this utility model, an ultrasonic probe is provided. See also Figure 1 , Figure 2 and Figure 3The ultrasonic probe may include a base 300, a first housing 100, a second housing 200, and at least two oil pipes 400. The base 300 may be an aluminum platform or any other suitable form, and the base 300 may provide positioning and support for the first housing 100, the second housing 200, and the at least two oil pipes 400.

[0029] The first housing 100 can be connected to the first side 310 of the base 300 and can be enclosed with the base 300 to form a first cavity 110. The first housing 100 can be connected to the base 300 by various suitable means such as adhesive. An ultrasonic core 111 can be disposed inside the first cavity 110. The first housing 100 can be an acoustic window shell, and when the ultrasonic probe is in use, the first housing 100 can directly contact the interior of the object to be examined.

[0030] The second housing 200 can be connected to the second side 320 of the base 300 and can enclose the base 300 to form a second cavity 210. The second housing 200 can be a central support. The second housing 200 is connected to the second side 320 of the base 300, while the first housing 100 is connected to the first side 310 of the base 300. The second housing 200 and the first housing 100 are located on opposite sides of the base 300 approximately along the axial direction of the ultrasonic probe. However, since the base 300 is not limited to having two opposite sides, the first housing 100 and the second housing 200 can be in contact with each other, see reference. Figure 5 and Figure 6 The first housing 100 and the second housing 200 can be respectively connected to the circumferential surface of the base 300 around the axis. In this case, the first housing 100 and the second housing 200 are in direct contact, and are located on opposite sides of the base 300 along the central axis of the ultrasonic probe. It can be considered that in such an ultrasonic probe, the first housing 100 is connected to the first side 310 of the base 300, while the second housing 200 is connected to the second side 320 of the base 300. The advantage of direct contact between the first housing 100 and the second housing 200 is that the base 300 typically provides weak positioning for the first housing 100; that is, only a small step on the base 300 positions the connection point of the first housing 100. However, after the second housing 200 is connected to the base 300, since it can directly contact the first housing 100, the position on the second housing 200 used for contact with the first housing 100 provides strong positioning for the first housing 100. Therefore, connecting the first housing 100 to the base 300 is simpler and more convenient.

[0031] The number of oil pipes 400 can be arbitrary. Each oil pipe 400 can pass through the second cavity 210 and connect to the first cavity 110, and the oil pipe 400 can have a connecting portion 410 and an extension portion 420. The connecting portion 410 can be connected to the base 300, and the extension portion 420 can extend outside the second cavity 210. The connecting portion 410 can be considered to be located inside the second cavity 210. When the ultrasonic probe is in use, the first cavity 110 needs to be filled with oil. For the ultrasonic probe provided in this application, oil can be injected into the first cavity 110 through the extension portion 420 of the oil pipe 400.

[0032] To address the issue of air bubbles appearing in the space enclosed by the acoustic window housing in existing ultrasonic probes, the inventors, through multi-faceted research and investigation, creatively identified the cause of these air bubbles. First, the inventors investigated the oil filling process during ultrasonic probe installation. After vacuum oil filling tests, multiple tests with different oil filling positions, and tests using different transparent acoustic window housings, it was found that the oil filling process was not the cause of the air bubbles in the space enclosed by the acoustic window housing. Next, the inventors investigated air leakage, successively eliminating leaks from the plug, bearings, and oil pipes. Based on the above research and investigation, the inventors creatively discovered that the main cause of air bubbles in existing ultrasonic probes is:

[0033] The aluminum platform provides weak positioning for the acoustic window housing. During the installation of the ultrasonic probe, the oil pipe is first connected to the aluminum platform. Subsequently, the aluminum platform is often assembled and connected to the middle support. The middle support provides strong positioning for the acoustic window housing. The acoustic window housing is then connected to the aluminum platform. After the acoustic window housing is connected to the aluminum platform, the middle support needs to be disassembled to fill the space enclosed by the acoustic window housing with oil through the oil pipe. After the oil is filled, the middle support needs to be reinstalled. During this process, since the installed middle support is in contact with the acoustic window housing, the middle support may press against the acoustic window housing when it is reinstalled. This may cause the connection between the acoustic window housing and the aluminum platform to loosen. Loosening of the connection between the acoustic window housing and the aluminum platform may lead to air leakage, which may then form air bubbles in the space enclosed by the acoustic window housing and the aluminum platform. In addition, since the oil filling operation usually relies on the operator's experience, after the oil filling is completed and the middle bracket is reinstalled, it may be found that the air bubbles in the space surrounded by the acoustic window shell and the aluminum platform were not completely expelled during the oil filling process. At this time, it is necessary to disassemble the middle bracket again, fill the oil again, and reinstall the middle bracket again. With repeated disassembly and reassembly of the middle bracket, the possibility of the connection between the acoustic window shell and the aluminum platform is greatly increased. It is equivalent to the repeated disassembly and reassembly of the middle bracket damaging the seal between the acoustic window shell and the aluminum platform, causing external gas to enter the space formed by the acoustic window shell and the aluminum platform, thus forming air bubbles.

[0034] Through creative work, the inventor discovered the cause of air bubbles forming in the space enclosed by the acoustic window housing and the aluminum platform in existing ultrasonic probes, and improved the existing ultrasonic probe structure. In the ultrasonic probe provided by this utility model, the first housing 100 can be an acoustic window housing, the second housing 200 can be a middle support, and the base 300 can be an aluminum platform. During installation, the oil pipe 400 can be connected to the base 300 first, followed by the second housing 200. The strong positioning effect of the second housing 200 on the first housing 100 allows for easy connection of the first housing 100 to the base 300. Subsequently, since the oil pipe 400 includes an extension portion 420 located outside the second cavity 210, oil can be injected into the oil pipe 400 through the end of the extension portion 420 away from the base 300 (i.e., the first port 430 shown in the figure). The oil pipe 400 is connected to the first cavity 110, allowing oil to be injected into the first cavity 110. During the oil filling process, it is not necessary to disassemble the second housing 200. The connection between the first housing 100 and the base 300 naturally maintains good sealing, making it difficult for external gas to enter the first cavity 110 and for air bubbles to form within it. It is understood that when oil is poured into the first cavity 110, the gas inside can be discharged through the oil pipe 400. That is, at least one of the at least two oil pipes 400 can be used to fill the first cavity 110 with oil. Furthermore, as the amount of oil in the first cavity 110 increases, the gas inside can be discharged to the outside through at least one oil pipe 400. Here, the oil pipe 400 used for filling the oil and the oil pipe 400 used for discharging the gas can be two different oil pipes. When oil is discharged from the oil pipe 400 used for discharging the gas, it can be considered that the first cavity 110 is full of oil.

[0035] The ultrasonic probe provided by this invention, during installation, connects the second housing 200 to the base 300. The second housing 200 positions the first housing 100, allowing it to be connected to the base 300. Then, oil can be injected into the first cavity 110 via the extension 420 of the oil pipe 400. This injection can be performed outside the second cavity 210, eliminating the need to disassemble the second housing 200. This avoids the sealing failure between the first housing 100 and the base 300 caused by repeated disassembly and reassembly of the second housing 200, thus preventing air bubbles from forming in the first cavity 110 due to a failed seal. With this ultrasonic probe, air bubbles are less likely to form in the first cavity 110, resulting in better imaging of the ultrasonic core 111.

[0036] In one embodiment of this utility model, see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The oil pipe 400 may have a first port 430 and a second port 440. The first port 430 may be located at the end of the extension portion 420 away from the base 300, and the second port 440 may be located at the end of the connecting portion 410 away from the first port 430. The oil pipe 400 may be connected to the first cavity 110 through the second port 440. The connection between the oil pipe 400 and the first cavity 110 through the second port 440 may be achieved by the second port 440 extending directly into the first cavity 110 to connect the oil pipe 400 to the first cavity 110, or by the second port 440 being connected to the first cavity 110 through a connecting member, or other various other forms. The first port 430 of at least two oil pipes 400 may form an oil inlet for oil to enter, and the first port 430 of at least two oil pipes 400 may form an outlet for gas to exit. Taking at least two oil pipes 400, including one oil inlet pipe and one vent pipe, as an example, oil can be injected into the first cavity 110 through the first port 430 of the oil inlet pipe. For the oil inlet pipe, the oil enters the oil inlet pipe through the first port 430 and enters the first cavity 110 through the second port 440 of the oil inlet pipe. For the vent pipe, the gas in the first cavity 110 enters the vent pipe through the second port 440 of the vent pipe and is discharged to the outside through the first port 430 of the vent pipe. When the first cavity 110 is full of oil, as oil is continuously injected into the first cavity 110, the oil in the first cavity 110 will enter the vent pipe through the second port 440 of the vent pipe and overflow to the outside through the first port 430 of the vent pipe. When oil overflows from the first port 430 of the vent pipe and no gas is discharged, it can be considered that the first cavity 110 is full of oil. Understandably, at least two oil pipes 400 can include any suitable number of oil inlet pipes and air outlet pipes. Such an ultrasonic probe, during installation, can provide a clearer indication of whether the first cavity 110 is filled with oil, and the injection of oil into the first cavity 110 via the oil pipes 400 is less likely to form air bubbles during the injection process.

[0037] For example, see Figure 3A connector 500 may be provided at one end of the connecting portion 410 near the base 300. The connector 500 can be threaded to the base 300. The connector 500 is hollow inside and can form a first channel 510. The oil pipe 400 can be connected to the first cavity 110 through the first channel 510. The base 300 needs to provide positioning and support for the first housing 100, the second housing 200, and at least two oil pipes 400. Therefore, the base 300 can usually include parts made of metal materials, while the oil pipes 400 can usually include parts supported by flexible materials. For example, the oil pipes 400 can include hoses made of polytetrafluoroethylene. In this case, it is difficult to directly connect the oil pipes 400 to the base 300. The connector 500 is provided at one end of the connecting portion 410 of the oil pipe 400 near the base 300. This makes it simpler and more convenient to connect the oil pipes 400 to the base 300. Moreover, the connection between the oil pipes 400 and the base 300 is easier to disassemble in this way. The oil pipe 400 is connected to the first cavity 110 through the first channel 510. Alternatively, one end of the connector 500 away from the oil pipe 400 can be directly inserted into the first cavity 110 to connect the oil pipe 400 to the first cavity 110. Or, the base 300 can be provided with a connecting channel, and the first channel 510 in the connector 500 can be connected to the connecting channel in the base 300 to connect the oil pipe 400 to the first cavity 110.

[0038] For example, see Figure 3 The base 300 may be provided with a second channel 330, and the connector 500 may be threaded to the second channel 330. The oil pipe 400 may be connected to the first cavity 110 in sequence through the first channel 510 and the second channel 330. With the oil pipe 400 connected to the first cavity 110 in this manner, the connector 500 does not need to extend into the first cavity 110, thus providing better sealing for the base 300. Furthermore, this connection between the connector 500 and the base 300 is easier to disassemble, making it easier to remove the oil pipe 400 from the base 300.

[0039] For example, see Figure 3The axial length (length L shown in the figure) of the extended portion 420 can be 35mm to 45mm. For example, the axial length L of the extended portion 420 can be 35mm, 37mm, 40mm, 42.8mm, or 45mm, etc. Preferably, the axial length L of the extended portion 420 can be 40mm. After the oil is filled into the first cavity 110, the extended portion 420 of the oil pipe 400 needs to be sealed. Usually, a sealing element can be set at the first pipe opening 430 on the extended portion 420 to seal the extended portion 420. If the axial length L of the extended portion 420 is too small, it will be difficult to set the sealing element; if the axial length of the extended portion 420 is too large, it will occupy too much space and make it difficult to design and assemble the overall structure. When the axial length L of the extended portion 420 is 35mm to 45mm, it is easy to set a sealing element at the first pipe opening 430 on the extended portion 420 to seal the extended portion 420, and the overall space occupied is reasonable.

[0040] For example, the tubing 400 may include a portion made of a flexible material. Preferably, the tubing 400 may include a portion made of polytetrafluoroethylene (PTFE). The tubing 400 may include a portion made of a flexible material with a certain degree of toughness, which facilitates bending of the tubing 400 to optimize its placement within the ultrasonic probe.

[0041] For example, at least a portion of the oil pipe 400 can be flattened. Preferably, the entire oil pipe 400 can be flattened. The flattened oil pipe 400 can remain flattened after oil is poured into the first cavity 110. The flattened oil pipe 400 can reserve space for the volume expansion of the oil. After the oil in the first cavity 110 expands due to heat, the oil can expand the flattened oil pipe 400. This can prevent the pressure inside the ultrasonic probe from becoming too high due to the expansion of the oil pipe 400 and the oil in the first cavity 110 due to heat.

[0042] For example, see Figure 3 , Figure 5 and Figure 6A sealing element 600 is detachably provided on the end of the extension portion 420 away from the base 300. After the first cavity 110 is filled with oil, the extension portion 420 needs to be sealed. The sealing element 600 detachably provided on the end of the extension portion 420 away from the base 300 ensures the sealing of the ultrasonic probe after installation and prevents air bubbles from forming in the first cavity 110. When the first cavity 110 needs to be filled with oil again, the sealing element 600 can be removed, and oil can be filled into the first cavity 110 through the extension portion 420. In this way, the ultrasonic probe may need to be filled with oil into the first cavity 110 multiple times during multiple uses, making it more convenient for multiple oil fillings.

[0043] For example, see Figure 2 and Figure 5 A mounting plate 211 can be disposed within the second cavity 210, and any suitable structure, such as a circuit board, can be disposed on the mounting plate 211. The mounting plate 211 can be connected to the second housing 200, and a clearance gap 212 can be formed between the mounting plate 211 and the second housing 200. Along the circumferential direction of the second housing 200, a portion of the second housing 200 can be connected to the mounting plate 211. In a plane perpendicular to the axis of the second housing 200, the projected area of ​​the mounting plate 211 can be smaller than the projected area of ​​the opening of the second housing 200. This allows the mounting plate 211 to be connected to the second housing 200, and a clearance gap 212 to be formed between the mounting plate 211 and the second housing 200. The extended portion 420 can pass through the clearance gap 212. Since the extended portion 420 of the oil pipe 400 is located outside the second cavity 210, a clearance gap 212 is required between the mounting plate 211 and the second housing 200 to allow the oil pipe 400 to pass through the second cavity 210. Depending on the different structures provided on the mounting plate 211, the oil pipe 400 needs to avoid the structures on the mounting plate 211 when passing through the second cavity 210. Therefore, the specific form of the avoidance gap 212 can be designed according to needs, as long as it can ensure that the oil pipe 400 passing through the avoidance gap 212 does not interfere with the structures on the mounting plate 211. This makes the overall structure of the ultrasonic probe more stable.

[0044] For example, see Figure 4The connection between the first housing 100 and the base 300 has a contact thickness (contact thickness H in the figure), which can be 0.5mm to 0.6mm. For example, the contact thickness H can be 0.5mm, 0.55mm, or 0.6mm. Preferably, the contact thickness H can be 0.55mm. The contact thickness H is thicker than that of the existing first housing 100, which enhances the sealing connection between the first housing 100 and the base 300. When the contact thickness H is 0.5mm to 0.6mm, the sealing connection between the first housing 100 and the base 300 is prevented from failing due to repeated disassembly and reassembly of the second housing 200, and thus the formation of air bubbles in the first cavity 110 due to the failure of the sealing connection between the first housing 100 and the base 300 is avoided. With such an ultrasonic probe, air bubbles are less likely to form in the first cavity 110, resulting in better imaging of the ultrasonic core 111. When the contact thickness H is thinner, the sealing connection between the first housing 100 and the base 300 is poorer. When the contact thickness H is too thick, it not only increases the cost, but also reduces the space of the first cavity 110.

[0045] According to another aspect of this utility model, see Figure 7 This invention provides a method for mounting an ultrasonic probe. The mounting method is applicable to any of the ultrasonic probes described above. The mounting method may include:

[0046] Step S10: Connect at least two oil pipes 400 to the base 300;

[0047] Step S20: Connect the second housing 200 to the base 300;

[0048] Step S30: Connect the first housing 100 to the base 300;

[0049] Step S40: Injecting oil into the first cavity 110 from the extension portion 420 of at least one oil pipe 400; and

[0050] Step S50: When the first cavity 110 and each oil pipe 400 are filled with oil, seal the end of each oil pipe 400 away from the base 300.
