Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an ultrasound probe. Furthermore, this utility model also relates to an ultrasound endoscope end-piece device including the aforementioned ultrasound probe and an ultrasound endoscope including the ultrasound end-piece device. Background Technology

[0002] With the development of medical device technology, endoscopic ultrasound has been widely used in clinical medicine. For example, endoscopic ultrasound is an electronic bronchoscope with ultrasound diagnostic and therapeutic functions. Its tip is equipped with an ultrasound probe for ultrasound diagnosis of tissues below the respiratory tract membrane. Guided by ultrasound images, a puncture needle is extended through the instrument channel to perform biopsy of internal tissues and obtain information on deep lesions in the respiratory tract.

[0003] For endoscopes with small ultrasound probes, a water-filled bladder is needed in clinical use. The bladder is fixed between the headstock and the ultrasound probe by a sealing ring, thus encasing the ultrasound probe.

[0004] However, in the existing technology, the distance between the sealing ring and the endoscope's illumination and optical camera is relatively close, while the field of view of the optical camera's photosensitive chip is relatively large. The sealing ring is likely to appear within the field of view of the optical camera, resulting in image overexposure.

[0005] Therefore, how to reduce image overexposure in ultrasound endoscopy is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an ultrasonic probe that can be applied to an ultrasonic endoscope with a water bladder, thereby reducing the overexposure of ultrasonic endoscope images.

[0007] Another objective of this invention is to provide an ultrasonic endoscope end device including the aforementioned ultrasonic probe, which can reduce image overexposure in ultrasonic endoscopes.

[0008] Another objective of this invention is to provide an ultrasonic endoscope including the aforementioned ultrasonic endoscope lens end device, which can reduce image overexposure.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An ultrasonic probe, used in an ultrasonic endoscope, includes a probe housing and an ultrasonic transducer disposed in the probe housing, wherein the probe housing is provided with:

[0011] A fixing part is used to connect with the head end mount of the ultrasonic endoscope;

[0012] A water bladder sealing ring mounting part is used to fit a water bladder sealing ring. The water bladder sealing ring mounting part is recessed into the surface of the fixing part at a position corresponding to the camera on the head end seat along the circumferential direction of the head end seat to form a groove. At least a portion of the water bladder sealing ring is disposed in the groove, so that the portion of the water bladder sealing ring corresponding to the groove along its circumferential direction does not appear in the field of view of the camera.

[0013] Optionally, the water bladder sealing ring mounting portion includes a protrusion protruding from the surface of the fixing portion, the protrusion forming a limiting step with the fixing portion, the limiting step being used to abut and limit the head end seat.

[0014] Optionally, the fixing part is provided with a first mounting hole, which is used to align with a second mounting hole on the head end seat to cooperate with a connector for connecting the fixing part and the head end seat.

[0015] Optionally, the probe housing is provided with a water bladder fixing step, which is located on the side of the water bladder sealing ring mounting part away from the fixing part.

[0016] An ultrasonic endoscope tip device includes:

[0017] The headstock is equipped with a camera;

[0018] In any of the above-mentioned ultrasonic probes, the fixing part of the ultrasonic probe is connected to the head end seat, and the groove of the ultrasonic probe corresponds to the camera along the circumference of the head end seat.

[0019] Optionally, a portion of the end face of the headstock facing the probe housing is flush with the side wall of the groove near the headstock.

[0020] Optionally, the probe housing is tilted relative to the head end mount toward the side away from the camera.

[0021] An ultrasonic endoscope includes an insertion part and any one of the above-mentioned ultrasonic endoscope lens devices, wherein the ultrasonic endoscope lens device is connected to the insertion part.

[0022] Optionally, the head end of the ultrasonic endoscope device is inclined relative to the axis of the insertion portion toward the side away from the camera.

[0023] Optionally, the ultrasonic endoscope is an ultrasonic bronchoscope.

[0024] The beneficial effects of the ultrasonic probe provided by this utility model are as follows: The ultrasonic probe is provided with a water-filled sealing ring mounting part. A groove is formed on the surface of the fixing part at the position of the camera on the headstock along the circumferential direction of the water-filled sealing ring mounting part. When the ultrasonic probe is applied to an ultrasonic endoscope, the fixing part of the probe housing is connected to the headstock, and the water-filled sealing ring is fitted onto the outer circumference of the water-filled sealing ring mounting part. At this time, due to the presence of the groove, the relative position of the portion of the water-filled sealing ring corresponding to the groove along its circumferential direction with respect to the camera on the headstock changes. That is, it is equivalent to causing the portion of the water-filled sealing ring corresponding to the groove along its circumferential direction to move radially downward relative to the camera on the headstock, thereby causing the portion of the water-filled sealing ring corresponding to the groove along its circumferential direction to avoid the field of view of the camera, and preventing the portion of the water-filled sealing ring corresponding to the groove along its circumferential direction from... Appearing within the camera's field of view, the groove corresponds to the camera's position on the headstock along its circumference. That is, the groove is located below the camera's field of view. Since the field of view faces the ultrasonic probe, it is sufficient to ensure that the water-filled sealing ring does not appear within the camera's field of view. Specifically, the water-filled sealing ring mounting part near the camera needs to be recessed radially. Water-filled sealing rings far from the camera will not interfere with the camera's field of view and therefore cannot appear within it. Thus, it is only necessary to restrict the water-filled sealing rings near the camera to be placed within the groove, ensuring that they do not appear within the camera's field of view. This avoids interference with the camera's field of view and prevents image overexposure caused by the water-filled sealing ring.

[0025] The ultrasonic endoscope device provided by this utility model includes the aforementioned ultrasonic probe and has the aforementioned beneficial effects.

[0026] The ultrasonic endoscope provided by this utility model includes the aforementioned ultrasonic endoscope lens end device and has the aforementioned beneficial effects. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0041] The core of this invention is to provide an ultrasonic probe for use in an ultrasonic endoscope with a water-filled bladder, which can reduce image overexposure in the ultrasonic endoscope. Another core aspect of this invention is to provide an ultrasonic endoscope lens device including the aforementioned ultrasonic probe, which can also reduce image overexposure in the ultrasonic endoscope. Yet another core aspect of this invention is to provide an ultrasonic endoscope including the aforementioned ultrasonic endoscope lens device, which can reduce image overexposure in the endoscope.

[0042] Please refer to Figure 1 and Figure 2 This utility model provides an ultrasonic probe for use in an ultrasonic endoscope, including a probe housing 1 and an ultrasonic transducer 2 disposed in the probe housing 1. The probe housing 1 has a fixing part 11 and a water-filled sealing ring mounting part 12. The fixing part 11 is used to connect with the head end seat 3 of the ultrasonic endoscope; the water-filled sealing ring mounting part 12 is used to fit a water-filled sealing ring 4 (e.g., Figure 5 and Figure 6 As shown), the water bladder sealing ring mounting portion 12 is recessed into the surface of the fixing portion 11 at a position corresponding to the camera 5 on the head end seat 3 along the circumferential direction, forming a groove 13. At least a portion of the water bladder sealing ring 4 is disposed within the groove 13, and the portion of the water bladder sealing ring 4 corresponding to the groove 13 along its circumferential direction does not appear within the field of view of the camera 5 (e.g., Figure 6 and Figure 7 (As shown).

[0043] It is understandable that the probe housing 1 serves as a support structure for the ultrasonic transducer 2, providing support for it. The ultrasonic transducer 2 can emit and receive ultrasonic waves, converting them into electrical signals for further transmission.

[0044] The key point of this embodiment is that by improving the structure of the probe housing 1, the relative positions of the water bladder sealing ring mounting part 12 and the fixing part 11 are changed. Since the water bladder sealing ring mounting part 12 is used to fit the water bladder sealing ring 4, and the fixing part 11 is used to connect the head end seat 3, and the camera 5 is mounted on the head end seat 3, in order to avoid the water bladder sealing ring 4 affecting the observation field of the camera 5 after it is installed on the water bladder sealing ring mounting part 12, the position of the water bladder sealing ring 4 relative to the head end seat 3 can be changed. That is, the position of the water bladder sealing ring 4 relative to the camera 5 is changed, so that the water bladder sealing ring 4 does not appear in the field of view of the camera 5.

[0045] Specifically, the water-filled sealing ring mounting portion 12 is recessed into the surface of the fixing portion 11 at the position of the camera 5 on the head end seat 3 along the circumferential direction, thereby forming a groove 13. When the ultrasonic probe is used in an endoscope to acquire ultrasonic images, the fixing portion 11 of the probe housing 1 is connected to the head end seat 3, and the water-filled sealing ring 4 is fitted onto the outer periphery of the water-filled sealing ring mounting portion 12. At this time, due to the presence of the groove 13, the portion of the water-filled sealing ring 4 corresponding to the groove 13 along its circumferential direction is located within the groove 13, thereby changing the relative position between the portion of the water-filled sealing ring 4 corresponding to the groove 13 along its circumferential direction and the camera 5 on the head end seat 3. That is, it is equivalent to causing the portion of the water-filled sealing ring 4 corresponding to the groove 13 along its circumferential direction to move radially downward relative to the camera 5 on the head end seat 3, thereby causing the portion of the water-filled sealing ring 4 corresponding to the groove 13 along its circumferential direction (including the portion recessed into the groove 13 and the portion radially protruding out of the groove 13) to avoid the field of view of the camera 5, so that the water-filled sealing ring 4... The portion of the groove 13 along its circumference does not appear within the field of view of the camera 5. Since the groove 13 corresponds to the position of the camera 5 on the head end seat 3 along its circumference, that is, the groove 13 is located below the field of view of the camera 5. Since the field of view of the camera 5 is oriented towards the ultrasound probe, it is sufficient to ensure that the water-filled sealing ring 4 does not appear within the field of view of the camera 5. That is, the water-filled sealing ring mounting part 12 near the camera 5 needs to be recessed in the radial direction. The water-filled sealing ring 4 away from the camera 5 will not interfere with the field of view of the camera 5, so it is impossible for it to appear within the field of view of the camera 5. Therefore, it is only necessary to restrict the water-filled sealing ring 4 near the camera 5 to be placed in the groove, ensuring that the water-filled sealing ring 4 does not appear within the field of view of the camera 5. This will avoid the water-filled sealing ring 4 interfering with the field of view of the camera 5, thereby avoiding image overexposure caused by the appearance of the water-filled sealing ring 4, improving image quality, and enhancing the clinical diagnosis and treatment experience.

[0046] It should be noted that the specific depth of the groove 13 is not limited in this embodiment, as long as the portion of the water bladder sealing ring 4 disposed in the groove 13 along its circumference (including the portion sunk into the groove 13 and the portion radially protruding out of the groove 13) does not appear within the field of view of the camera 5. In addition, the specific shape of the groove 13 is not limited in this embodiment. It can be understood that the shape of the groove 13 matches the shape of the water bladder sealing ring 4 so that the water bladder sealing ring 4 can be installed.

[0047] Additionally, when applying this ultrasonic probe to an ultrasonic endoscope, to achieve rapid installation and positioning of the probe housing 1 and the headstock 3, please refer to... Figure 4In some embodiments, the water bladder sealing ring mounting portion 12 includes a protrusion protruding from the surface of the fixing portion 11, the protrusion forming a limiting step 14 with the fixing portion 11, the limiting step 14 being used to abut and limit the head end seat 3. In some embodiments, the protrusion is located at a position of the water bladder sealing ring mounting portion 12 away from the groove 13. In other words, the water-filled sealing ring mounting part 12 and the fixing part 11 are eccentrically positioned, partially offset in the radial direction of the probe housing 1. This allows the water-filled sealing ring mounting part 12 to be recessed into the surface of the fixing part 11 at the position corresponding to the camera 5 on the headstock 3, while protruding from the surface of the fixing part 11 at the position opposite to the groove 13. This ensures that the portion of the water-filled sealing ring 4 corresponding to the groove 13 along its circumference does not appear within the field of view of the camera 5. Simultaneously, the portion of the water-filled sealing ring mounting part 12 protruding from the surface of the fixing part 11, i.e., the limiting step 14, can stop and limit the headstock 3. That is, when the ultrasonic probe is installed onto the headstock 3, the fixing part 11 and the headstock 3 are assembled until the end of the headstock 3 facing the probe housing 1 abuts against the limiting step 14, indicating that the fixing part 11 and the headstock 3 are properly installed. This structure is simple and easy to process and assemble.

[0048] Additionally, for easier connection between the fixing part 11 and the head end seat 3, please refer to... Figure 8 and Figure 9 In some embodiments, the fixing part 11 is provided with a first mounting hole 111, which is used to align with a second mounting hole 31 on the head end seat 3 to cooperate with the connector 6 for connecting the fixing part 11 and the head end seat 3. In some embodiments, the first mounting hole 111 is provided on the portion of the fixing part 11 that protrudes from the water bladder sealing ring mounting part 12. That is, in this embodiment, the first mounting hole 111 is provided on the portion of the fixing part 11 that protrudes from the water bladder sealing ring mounting part 12. Since the first mounting hole 111 is located on the portion of the fixing part 11 that protrudes from the water bladder sealing ring mounting part 12, it is convenient to connect with the connector 6, making the connection between the fixing part 11 and the head end seat 3 convenient. It should be noted that the first mounting hole 111 corresponds to the second mounting hole 31. In this embodiment, the specific number and distribution of the first mounting hole 111 and the second mounting hole 31 are not limited, as long as a stable connection between the fixing part 11 and the head end seat 3 can be achieved. Furthermore, this embodiment does not limit the specific structure of the connector 6. The connector 6 can be a fastener such as a bolt or a pin, as long as the connector 6 can fix the fixing part 11 to the head end seat 3 through the connection with the first mounting hole 111 and the second mounting hole 31. In some embodiments, the connector 6 is a pin. After the pin passes through the first mounting hole 111 and the second mounting hole 31, it is tightened to the head end seat 3 by a screw 61, so that the pin is tightened by the screw 61. A surface adhesive 62 is provided at the end of the screw 61 away from the pin to achieve the function of sealing and insulation.

[0049] Therefore, it can be seen that the outer peripheral surface of the probe housing 1 in this embodiment is not a straight structure with uniform dimensions, but a non-straight structure with groove 13 and limiting step 14, so as to meet the installation requirements of water bag sealing ring 4 and realize the connection between fixing part 11 and head end seat 3.

[0050] Additionally, please refer to Figure 2 In some embodiments, the probe housing 1 has a water bladder fixing step 15 at the end of the water bladder sealing ring mounting part 12 away from the fixing part 11. It can be understood that the water bladder wraps around the outer periphery of the ultrasonic probe. When the water bladder sealing ring 4 fixes the water bladder to the probe housing 1, the water bladder fixing step 15 supports the part of the water bladder near the water bladder sealing ring 4, which helps to provide better support for the part of the water bladder near the water bladder sealing ring 4.

[0051] For further information, please continue to refer to [link / reference]. Figure 2 In some embodiments, the probe housing 1 is provided with a water bladder outlet 16 near the water bladder fixing step 15. Water can be filled into the water bladder through the water bladder outlet 16. The water bladder outlet 16 is located at the water bladder fixing step 15, which helps to make the water bladder expand smoothly when filled with water.

[0052] Additionally, please refer to Figure 1 In some embodiments, the fixing part 11 is provided with an overflow groove 17, which is used to accommodate excess adhesive on the mating surface between the fixing part 11 and the head end seat 3 after they are connected. It is understood that when applying an ultrasonic probe to an ultrasonic endoscope, adhesive can be applied to the mating surface between the fixing part 11 and the head end seat 3 to improve the connection strength, making the ultrasonic probe and the head end seat 3 more firmly connected. In this embodiment, by providing an overflow groove 17 to accommodate excess adhesive, adhesive leakage can be avoided.

[0053] In addition to the aforementioned ultrasonic probe, this embodiment of the invention also provides an ultrasonic endoscope end device including the ultrasonic probe disclosed in the above embodiments. The ultrasonic endoscope end device further includes a headstock 3, which is equipped with a camera 5. The fixing part 11 of the ultrasonic probe is connected to the headstock 3, and the groove 13 of the ultrasonic probe corresponds to the camera 5. The structure of other parts of this ultrasonic endoscope end device is described in the prior art and will not be repeated here.

[0054] In other words, after connecting the ultrasonic probe to the headstock 3, the groove 13 of the probe housing 1 corresponds to the camera 5 on the headstock 3. In this way, when the water bladder sealing ring 4 is fitted onto the water bladder sealing ring mounting part 12, the part of the water bladder sealing ring 4 that is sunk into the groove 13 does not appear in the field of view of the camera 5. This has the same beneficial effect as the ultrasonic probe mentioned above, and can reduce the overexposure phenomenon of ultrasonic endoscope images.

[0055] It should be noted that this embodiment does not limit the specific connection method between the fixing part 11 and the head end seat 3, as long as the connection between the two can be achieved. In some embodiments, the head end seat 3 is provided with a socket, and the fixing part 11 is inserted into the socket, that is, the fixing part 11 and the head end seat 3 are plugged in.

[0056] Further, please refer to Figure 2 In some embodiments, after the fixing part 11 is connected to the head end seat 3, the end face of the head end seat 3 facing the probe housing 1 is flush with the end face of the fixing part 11 facing the water bag sealing ring mounting part 12, that is, the groove 13 is located between the probe housing 1 and the head end seat 3. This helps to make the structure compact and reduce the overall structural space of the ultrasound end lens device.

[0057] In some embodiments, the probe housing 1 is tilted relative to the headstock 3 towards the side away from the camera 5. This causes the groove 13 on the probe housing 1 to move further away from the camera 5 along and perpendicular to the insertion direction of the ultrasonic endoscope lens device, thereby further preventing the portion of the water-filled sealing ring 4 submerged in the groove 13 from appearing within the field of view of the camera 5, further reducing the risk of overexposure of the endoscope. It should be noted that this embodiment does not limit the specific angle at which the probe housing 1 is tilted relative to the headstock 3 towards the side away from the camera 5; those skilled in the art can set it according to actual needs.

[0058] In some embodiments, the probe housing 1 of the ultrasound probe is detachably connected to the headstock 3. That is, by disassembling, the ultrasound probe can be separated from the headstock 3, making the ultrasound probe an independent structural component. This improves the versatility of the ultrasound probe, allowing it to be used in various ultrasound endoscopes, thereby reducing costs.

[0059] Additionally, please refer to Figure 8 In some embodiments, the headstock 3 is provided with an inclined surface 32 that is tilted away from the probe housing 1 of the ultrasonic probe, and the camera 5 is disposed on the inclined surface 32. This helps to expand the field of view of the camera 5 and avoid the ultrasonic probe from obstructing the field of view of the camera 5.

[0060] Furthermore, in some embodiments, the lighting window 33 is disposed on the inclined surface 32, and the lighting window 33 is disposed close to the camera 5.

[0061] It should be noted that the above embodiments do not limit the specific structure of the camera 5, and those skilled in the art can refer to related technologies. In some embodiments, the camera 5 includes an optical lens and a CMOS / CCD photosensitive chip, which can convert light into electrical signals for further transmission. It is understood that the CMOS / CCD photosensitive chip has an extended field of view and a relatively large field of view, which is particularly suitable for the scheme disclosed in the embodiments of this utility model. That is, by improving the structure of the probe housing 1, the portion of the water bladder sealing ring 4 that is submerged in the groove 13 will not appear within the field of view of the camera 5.

[0062] In addition, it should be noted that the other parts of the headstock 3 can refer to relevant technologies, which will not be elaborated on in this article. For example, the headstock 3 is provided with an instrument channel and a water bag channel, etc.

[0063] In addition to the aforementioned ultrasonic endoscope lens end device, this utility model also provides an ultrasonic endoscope including the ultrasonic endoscope lens end device disclosed in the above embodiments, the ultrasonic endoscope further including an insertion part 7 (such as...). Figure 3 As shown), the ultrasonic endoscope end device is connected to the insertion part 7.

[0064] Since the ultrasonic endoscope includes the ultrasonic endoscope lens device disclosed in any of the above embodiments, it has the same beneficial effects as the ultrasonic endoscope lens device described above, and will not be repeated here.

[0065] Furthermore, in some embodiments, the headstock 3 of the ultrasonic endoscope device is inclined relative to the axis of the insertion portion 7 toward the side away from the camera 5. This helps to expand the field of view of the camera 5 and prevent the insertion tube wall of the insertion portion 7 from affecting the field of view of the camera 5. It should be noted that this embodiment does not limit the specific angle at which the headstock 3 of the ultrasonic endoscope device is inclined relative to the axis of the insertion portion 7 toward the side away from the camera 5, and those skilled in the art can set it according to actual needs.

[0066] Furthermore, the above embodiments do not limit the specific type of ultrasonic endoscope, as long as the ultrasonic endoscope is suitable for the solution provided by the embodiments of this utility model.

[0067] In some embodiments, the ultrasound endoscope is an ultrasound bronchoscope. It is understood that the application scenario for ultrasound bronchoscopes is inside the bronchial lumen, and its ultrasound probe is relatively small. In clinical use, a water-filled balloon is needed to achieve a close fit with the bronchial wall. Therefore, the ultrasound probe solution disclosed in the embodiments of this utility model is suitable.

[0068] Furthermore, the above embodiments do not limit the structure of other parts of the ultrasonic endoscope, for example, such as Figure 10As shown, the ultrasound endoscope includes an insertion section 7, an operation section 8, a light guide section 9, and an ultrasound connector 10. The insertion section 7 includes a curved section with different bending directions and a passively bent flexible tube. The operation section 8 includes a lever for controlling the curved section, a suction structure, an instrument channel inlet, and a smart button. The light guide section 9 is connected to the light source and processor of the ultrasound endoscope to output optical signals to the processor. The ultrasound connector 10 is connected to the ultrasound host to output ultrasound signals to the ultrasound host. For details, please refer to relevant technologies; further details are omitted here.

[0069] It should also be noted that, in this specification, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0070] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0071] The ultrasonic probe, ultrasonic endoscope end-piece device, and ultrasonic endoscope provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
