[0035] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0036] The purpose of this application is to overcome the defects and deficiencies in the prior art and provide a transesophageal ultrasound probe. This transesophageal ultrasound probe aims to solve the problem that the soft elastic film on the transducer surface of the transesophageal ultrasound probe adheres to the inner surface of the ultrasound lens or housing to transmit the sound waves emitted by the ultrasound transducer to the housing and then to the outside. After long-term use, the soft elastic film is easily deformed and damaged by pressure. Furthermore, because the transesophageal ultrasound probe rotates continuously, the coupling medium between the ultrasound transducer and the housing may slowly leak out due to the lack of sealing in the side open spaces. This leads to problems such as the sound waves emitted by the ultrasound transducer not being able to pass through the housing properly and the ultrasound lens not being able to emit sound outwards.
[0037] Figure 1 is a schematic diagram of an embodiment of the transesophageal ultrasound probe of this application. The transesophageal ultrasound probe includes a probe tip 50, a probe extension assembly 60, and a handle assembly 70. The probe extension assembly 60 includes an insertion tube 600 and a transmission component 601. The two ends of the insertion tube 600 are connected to the housing 40 and the handle assembly 70, respectively. When the user holds the handle assembly 70 and moves it, the insertion tube 600 can drive the probe tip 50 to move within the body for ultrasound detection. The transmission component 601 drives the probe tip 50 and the handle assembly 70, transmitting the user's rotational operation on the handle assembly 70 to a specific component within the probe tip 50, causing that component to rotate. For example, the transmission component 601 drives the rotating component 30 to rotate. The insertion tube 600 has a hollow structure, and the transmission component 601 is located inside the insertion tube 600. The transmission component 601 can be, but is not limited to, a metal rope, and forms a loop transmission line to achieve forward and reverse rotation.
[0038] As shown in Figure 1, the handle assembly 70 includes a handle 700 and an operating component 701. The handle 700 is connected to the insertion tube 600, and the operating component 701 is located within the handle 700. The handle 700 is designed for easy gripping by the user, and the operating component 701 is used to control the rotation of a specific component within the probe tip 50. For example, the transmission component 601 drives the operating component 701 and the rotating component 30, thereby transmitting the motion of the operating component 701 to the probe tip 50 and converting it into rotational motion.
[0039] As shown in Figures 2 and 3, Figure 2 is a structural schematic diagram of the probe tip in Figure 1, and Figure 3 is an exploded structural schematic diagram of the probe tip in Figure 2. The probe tip 50 includes a transducer 10, a rotating component 30, and a housing 40. The transducer 10 is an ultrasonic transducer used to emit ultrasonic waves to the outside world and receive ultrasonic waves reflected back from the outside world. Specifically, the working surface of the ultrasonic transducer can emit sound waves, which propagate outward through the area of the housing 40 corresponding to the working surface, and receive the reflected echoes on the selected tissue volume. The computer can synthesize image data based on the echoes and generate an image that can be displayed on an image display (video monitor, printer, etc.).
[0040] Optionally, in some embodiments, the transducer surface has a soft, elastic film to assist in the transmission and reception of ultrasonic waves. The rotating component 30 drives the transducer 10 to rotate, and the transmission component 601 is connected to the rotating component 30, thereby ultimately driving the transducer 10 to rotate. The housing 40 has a cavity 403 for accommodating the rotating component 30 and the transducer 10. Simultaneously, the housing 40 has a certain degree of rigidity to protect the rotating component 30 and the transducer 10.
[0041] In some embodiments, as shown in Figures 4, 5, and 7, Figure 4 is a cross-sectional view of the probe tip AA in Figure 2, Figure 5 is another view of the cross-sectional view of the probe tip AA in Figure 2, and Figure 7 is a partial view of the probe tip shown in Figure 4. The outer wall of the rotating member 30 or the transducer 10 is provided with a first limiting portion 202, and the cavity wall of the housing 40 has a first region 4030 with a second limiting portion 203 and a second region 4031 facing the working surface of the transducer 10. The first limiting portion 202 and the second limiting portion 203 engage in a limiting cooperation to prevent the rotating member 30 or the transducer 10 from approaching the second region 4031.
[0042] In some embodiments, as shown in Figures 4, 5 and 7, when the second limiting part 203 and the first limiting part 202 are in a limiting engagement state, there is a gap 100 between the transducer 10 and the second region 4031.
[0043] In some embodiments, as shown in Figures 4, 5 and 7, the first limiting part 202 and the second limiting part 203 both surround the outer periphery of the rotating member 30, and the first limiting part 202 and the second limiting part 203 are sealed together by a connecting adhesive so that the gap 100 is in a sealed space.
[0044] In some embodiments, as shown in Figures 4, 5, and 7, the housing 40 includes a first housing 400 and a second housing 401, which are connected to form a cavity 403. A second limiting portion 203 and a second region 4031 are located in the first housing 400, and a base 402 is disposed in the cavity 403 and fixed to the second housing 401.
[0045] Optionally, in some embodiments, the base 402 includes a circular base 4021 and a protruding column 4020 protruding from one side of the circular base 4021. A snap-fit groove 4010 is provided on the inner wall of the second housing 401, and the circular base 4021 is embedded in the snap-fit groove 4010, so that the base 402 and the second housing 401 snap-fit into each other. The base 402 and the second housing 401 provide support for the rotation of the rotating member 30. Optionally, the circular base 4021 can also be connected to the snap-fit groove 4010 by adhesive for further secure snap-fit.
[0046] As shown in Figures 3, 4 and 5, optionally, the rotating member 30 includes a transmission member 20, a receiving member 301 and a rotating part 305. The transmission member 20 is connected to the transducer 10 and also to the transmission member 601, so that the transmission member 20 can drive the transducer 10 to rotate.
[0047] The rotating part 305 is located between the receiving member 301 and the base 402. The receiving member 301 has a first surface 303 and a second surface 304 facing away from each other. The first surface 303 faces the base 402, and the second surface 304 faces the transmitting member 20. The first surface 303 has a groove 3030, and both the rotating part 305 and the protruding column 4020 are located in the groove 3030. The rotating part 305 is also mounted on the base 402, and more specifically, it is rotatably mounted on the protruding column 4020. The second surface 304 has a protrusion 3040, and the transmitting member 20 is a concave body. A portion of the transducer 10 is embedded in the opening of the concave body, and a fixing hole 102 is provided at the bottom of the concave body. The fixing hole 102 is fitted onto the protrusion 3040.
[0048] Optionally, in some embodiments, the rotating part 305 is further provided with a rotating auxiliary member 3020. The rotating auxiliary member 3020 is disposed within the groove 3030 and located between the first surface 303 and the base 402. More specifically, the rotating auxiliary member 3020 is installed between the rotating part 305 and the protruding column 4020. The rotating auxiliary member 3020 may be, but is not limited to, a spherical steel ball. The rotating auxiliary member 3020 is used to make the rotation of the rotating part 305 relative to the base 402 smoother.
[0049] The receiver 301 has an annular receiving groove 3022 on its protrusion 3040 peripheral wall, and the transmission member 601 is wound around the receiving groove 3022. Optionally, the transmission member 601 can be, but is not limited to, a metal rope. When the transmission member 601 rotates cyclically, because the rotating part 305 can rotate relative to the base 402, the transmission member 601 can drive the rotating receiver 301 to rotate, which in turn drives the transmission member 20 to rotate, and finally drives the transducer 10 to rotate. Optionally, in some embodiments, the rotating part 305 can be, but is not limited to, a bearing. Because the angle at which the stationary transducer 10 emits ultrasonic waves is limited, it is necessary to use the rotating part 30 to drive the transducer 10 to emit and receive ultrasonic waves at more angles, thereby obtaining a more comprehensive detection image.
[0050] In earlier designs, an ultrasonic lens was placed between the transducer and the adjacent housing. The ultrasonic lens was a soft, elastic film that adhered to the inner surface of the housing to transmit the ultrasonic waves emitted by the transducer to the housing and then to the outside. The transducer was usually close to the ultrasonic lens. As a result, during the long-term rotation of the transducer, the ultrasonic lens may be compressed and rubbed, causing it to deform and be damaged. Furthermore, because the transducer rotates continuously, after long-term use, the coupling medium between the transducer and the housing may slowly leak out due to the lack of sealing of the side open space, resulting in increased ultrasonic transmission loss.
[0051] To solve the above-mentioned technical problems, this application provides a corresponding embodiment as shown in FIG7. The cavity 403 formed by the housing 40 is divided into a first region 4030 and a second region 4031 by the contact fit between the transfer member 20 and the cavity wall. An annular body 200 is provided around the outer periphery of the transfer member 20. The first region 4030 of the cavity wall of the housing 40 has an annular stepped surface 201. The stepped surface 201 is disposed opposite to the second region 4031 of the cavity wall of the housing 40, forming an annular second limiting part 203. One side wall of the annular body 200 faces the second region 4031 of the cavity wall of the housing 40, forming a first limiting part 202. One side of the annular body 200 contacts the annular stepped surface 201. In this embodiment, the annular body 200 and the annular stepped surface 201 are in contact, thereby preventing the rotating member 30 or the transducer 10 from approaching the second region 4031 of the cavity wall of the housing 40.
[0052] In another embodiment, as shown in Figures 7 and 8, Figure 8 is a partial structural schematic diagram of another embodiment of the transesophageal ultrasound probe of this application. An annular body 200 is provided on the cavity wall of the housing 40, and an annular stepped surface 201 is provided on the transmission member 20. The stepped surface is disposed away from the second region 4031 of the cavity 403 wall of the housing 40, forming an annular second limiting part 203. One side wall of the annular body 200 faces the second region 4031 of the transmission member 20, forming a first limiting part 202. One side of the annular body 200 contacts the stepped surface, thereby achieving a snap-fit.
[0053] The above two embodiments are merely two ways in which the first limiting part 202 and the second limiting part 203 achieve limiting in this application. Other methods of use can also achieve the limiting effect of the first limiting part 202 and the second limiting part 203 in this application, and are also within the protection scope of this application, and will not be elaborated here. By engaging the first limiting part and the second limiting part, the rotating component or transducer can be prevented from approaching the second region of the cavity wall of the housing, thereby avoiding long-term extrusion pressure on the surface of the ultrasonic transducer, which could cause cracking. Simultaneously, the airtightness of the sealed cavity can be maintained, preventing the loss of the coupling medium.
[0054] Optionally, the esophageal ultrasound probe embodiment of this application may not include an ultrasound lens, that is, there is no ultrasound lens between the transducer 10 and the second region 4031 of the cavity wall of the housing 40.
[0055] As shown in Figures 6 and 7, Figure 6 is a schematic diagram of another exploded structure of the probe tip in Figure 2. The second housing 401 is also provided with an elastic element 300, which is located between the rotating member 30 and the base 402. Optionally, the elastic element 300 has a through hole (not shown), and the elastic element 300 is sleeved on the protruding column 4020 of the base 402 through the through hole to separate the circular base 4021 and the rotating member 30. Optionally, the elastic element 300 can be, but is not limited to, an elastic metal sheet with a through hole in the middle. Since the transducer 10 and the rotating member 30 both have a certain mass, if the first limiting part 202 and the second limiting part 203 are simply locked together, the locking of the first limiting part 202 and the second limiting part 203 may not be secure enough under the action of gravity. Therefore, the elastic element 300 is provided to give the transmission member 20 a force toward the first housing 400, thereby making the first limiting part 202 and the second limiting part 203 fit tightly together.
[0056] As shown in Figures 4 and 7, because the transducer 10 needs to rotate, a certain gap 100 is provided between the surface of the transducer 10 and the first housing 400, so that the transducer 10 will not come into contact with the inner wall of the first housing 400 during rotation, thus preventing damage to the transducer 10. The gap 100 between the transmission member 20 and the second region 4031 of the housing 40 is greater than the threshold, thereby forming a sealed cavity with the transducer 10, the first housing 400, and the transmission member 20.
[0057] Optionally, part or all of the gap 100 may be filled with an ultrasonic coupling medium, and the ultrasonic coupling medium may be in direct contact with the transducer 10 and the second region 4031, that is, there is no ultrasonic lens in the gap 100.
[0058] As shown in Figures 6 and 7, a third limiting part 204 is provided at the connection between the transmission member 20 and the outer wall of the transducer 10, that is, at the outer periphery of the transmission member 20. A fourth limiting part 205 is provided on the outer wall of the transducer 10. The force applied by the elastic member 300 causes the third limiting part 204 to be pressed towards the fourth limiting part 205, thereby making the transmission member 20 and the transducer 10 tightly connected.
[0059] Optionally, in some embodiments, the third limiting part 204 is located in the direction of the first limiting part 202 toward the first housing 400, and the fourth limiting part 205 is located on the outer wall of the transducer 10. The third limiting part 204 is a protrusion protruding toward the first housing 400, and the fourth limiting part 205 is a recessed platform that cooperates with the third limiting part 204. The elastic member 300 applies pressure to the third limiting part 204 toward the first housing 400, so that the protrusion of the third limiting part 204 can abut against the recessed platform of the fourth limiting part 205, so that the two are tightly engaged. At the same time, a connecting adhesive is provided between the third limiting part 204 and the fourth limiting part 205. The connecting adhesive is used to further connect the transmission member 20 and the transducer 10, so that the transmission member 20 and the transducer 10 form a whole.
[0060] The transesophageal ultrasound probe provided in this application embodiment can prevent the rotating part from approaching the second region of the cavity wall of the adjacent housing, thereby avoiding the surface of the ultrasound transducer from cracking due to long-term compressive stress.
[0061] Furthermore, a gap of a stable size is left between the ultrasonic transducer and the inner surface of the housing to fill the coupling medium. This ensures that the capacity of the coupling medium remains essentially stable, preventing its loss.
[0062] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
