Description

Technical Field

[0001] The present invention relates to the field of medical treatment evaluation, and particularly relates to an evaluation device, method for the result of ultrasonic treatment of rhinitis, and a nasal cavity ultrasonic treatment device. Background Art

[0002] Hypertrophy of nasal mucosa is a typical clinical manifestation of rhinitis. In some rhinitis cases, extensive hyperplasia and hypertrophy of nasal mucosa will occur, mainly due to long-term inflammatory stimulation of nasal mucosa, which causes deposition of submucosal glands or submucosal collagen, resulting in hypertrophy of nasal mucosa. The hypertrophy will cause obvious nasal congestion symptoms in patients, and it is necessary to deal with the hypertrophic mucosa. In the related art, minimally invasive surgeries for rhinitis treatment include inferior turbinate plasty, plasma radiofrequency ablation, and ethmoid sinus resection, etc. Mainly, surgeries should be performed on the middle turbinate or inferior turbinate of the nose. However, these surgeries will cause trauma to the tissues in the nasal cavity, making the recovery period of patients longer. High-intensity ultrasound belongs to a non-radiative treatment, which does not need to damage the tissue surface, especially the nasal mucosa, and has strong real-time performance. If high-intensity ultrasound is used for ablation or nerve block of rhinitis, there is no trauma at all, which can improve the treatment experience of patients and shorten the recovery time of patients. Currently, CT (Computed Tomography) or magnetic resonance imaging is used to evaluate the result of ultrasonic treatment of rhinitis, but both of these methods lack real-time evaluation of the treatment result of ultrasonic treatment of rhinitis, making the real-time performance of ultrasonic treatment poor, unable to timely reflect the effectiveness of ultrasonic treatment of rhinitis, having the risk of secondary treatment, increasing the work intensity of staff to a certain extent, and reducing the treatment experience of patients.

[0030] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for explaining the present invention, rather than for limiting the protection scope of the present invention.

[0031] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0032] In the following description, a large number of details are explored to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0033] The inventors' research found that nasal mucosa hypertrophy is a typical clinical manifestation of rhinitis. In some cases of rhinitis, extensive hyperplasia and hypertrophy of the nasal mucosa occur, mainly due to long-term inflammatory stimulation of the nasal mucosa, which causes submucosal gland or submucosal collagen deposition, resulting in nasal mucosa hypertrophy. The hypertrophy will cause obvious nasal congestion symptoms in patients, and it is necessary to treat the hypertrophic mucosa. In related technologies, minimally invasive surgeries for the treatment of rhinitis include inferior turbinate plasty, plasma radiofrequency ablation, and ethmoid sinus resection, etc. Mainly, surgeries should be performed on the middle turbinate or inferior turbinate of the nose. However, these surgeries will cause trauma to the tissues in the nasal cavity, resulting in a longer recovery period for patients. High-intensity ultrasound is a non-radiative treatment that does not require damaging the tissue surface, especially the nasal mucosa, and has strong real-time performance. If high-intensity ultrasound is used for ablation or nerve block of rhinitis, there is no trauma at all, which can improve the patient's treatment experience and shorten the patient's recovery time. Currently, CT (Computed Tomography) or magnetic resonance imaging is used to evaluate the results of ultrasound treatment for rhinitis, but both of these methods lack real-time evaluation of the treatment results of ultrasound treatment for rhinitis, resulting in poor real-time performance of ultrasound treatment, unable to timely reflect the effectiveness of ultrasound treatment for rhinitis, with the risk of secondary treatment, increasing the work intensity of staff to a certain extent, and reducing the patient's treatment experience.

As Figure 1 shown, in an exemplary embodiment, an evaluation device for the results of ultrasound treatment of rhinitis includes: an acquisition module 110, a first image processing module 120, a second image processing module 130, and a result evaluation module 140.

[0035] The first image processing module 110 is used to obtain a first nasal mucosa image and a second nasal mucosa image. The first nasal mucosa image is obtained by sampling the nasal mucosa before ultrasonic rhinitis surgery through an imaging transducer, and the second nasal mucosa image is obtained by sampling the nasal mucosa during or after ultrasonic rhinitis surgery through an imaging transducer.

[0036] Please refer to Figure 2 , Figure 2 which is a schematic diagram of a nasal cavity ultrasound treatment device and a display terminal shown in an exemplary embodiment of the present invention.

[0037] It should be noted that the first nasal mucosa image is the nasal mucosa image of the patient before treating rhinitis, and the second nasal mucosa image is the nasal mucosa image of the patient during the real-time treatment process or after the treatment is completed. As Figure 2As shown, an imaging transducer can be used to collect images of the nasal mucosa in the nasal cavity to obtain a first nasal mucosa image and a second nasal mucosa image, and the collected first nasal mucosa image and second nasal mucosa image are transmitted to a display terminal through a transmission line for display.

The multiple preoperative mucosa thicknesses are H 11 , H 12 , H 13 , H 14 ……H 1n ; the preoperative mucosa thickness determination unit is configured to determine the first nasal mucosa thickness H1 according to the multiple preoperative mucosa thicknesses; and then the preoperative mucosa volume determination unit performs a multiplication calculation on the first nasal mucosa thickness H1, the preoperative mucosa length L1, and the mucosa coefficient K to obtain the first nasal mucosa volume V1.

[0042] The determination expression of the first nasal mucosa volume V1 is as shown in (1):

[0043] V1 = K * H1 * L1 (1)

[0044] In expression (1), V1 is the first nasal mucosa volume, H1 is the first nasal mucosa thickness, L1 is the preoperative mucosa length, and K is the mucosa coefficient.

[0045] The second image processing module 130 is configured to perform point sampling on the second nasal mucosa image to obtain the second nasal mucosa thickness and the second nasal mucosa volume.

[0047] Specifically, as Figure 3 shown, the postoperative sampling unit performs point sampling on the nasal mucosa at the same positions (A, B, C, D, etc.) in the second nasal mucosa image as in the first nasal mucosa image, to obtain the postoperative mucosa thicknesses at multiple corresponding positions and the postoperative mucosa length L2 from the first position to the last position. The multiple postoperative mucosa thicknesses are H 21 , H 22 , H 23 , H 24 ……H 2n ; the postoperative mucosa thickness determination unit determines the second nasal mucosa thickness H2 according to the multiple postoperative mucosa thicknesses; then the postoperative mucosa volume determination unit performs a product calculation on the second nasal mucosa thickness H2, the postoperative mucosa length L2, and the mucosa coefficient K to obtain the second nasal mucosa volume V2.

[0048] The determination expression of the second nasal mucosa volume is as shown in (2):

[0049] V2 = K * H2 * L2 (2)

[0050] In expression (2), V2 is the second nasal mucosa volume, L2 is the postoperative mucosa length, H2 is the second nasal mucosa thickness, and K is the mucosa coefficient.

[0051] In an embodiment of the present invention, the preoperative mucosa thickness determination unit includes: a preoperative mucosa thickness processing subunit configured to perform a weighted average calculation on the multiple preoperative mucosa thicknesses to obtain the first nasal mucosa thickness. Among them, the first nasal mucosa thickness is obtained from the preoperative mucosa thicknesses at multiple different positions before treatment. A weighted average calculation is performed on the multiple preoperative mucosa thicknesses to obtain the first nasal mucosa thickness H1. The determination method of the first nasal mucosa thickness H1 is as shown in expression (3):

[0052]

[0053] In expression (3), H1 is the first nasal mucosa thickness, H11 ,H 12 ,H 13 ……H 1n is the preoperative mucosal thickness at each position, f 11 ,f 12 ,f 13 ……f 1n is the weight corresponding to each preoperative mucosal thickness; n is the number of preoperative mucosal thicknesses, and n is an integer greater than or equal to 1.

[0054] Similarly, the postoperative mucosal thickness determination unit includes: a postoperative mucosal thickness processing subunit for performing a weighted average calculation on multiple postoperative mucosal thicknesses to obtain a second nasal mucosal thickness. Among them, the second nasal mucosal thickness is obtained from the postoperative mucosal thickness at the corresponding position during or after treatment. The postoperative mucosal thickness processing subunit performs a weighted average calculation on multiple postoperative mucosal thicknesses to obtain a second nasal mucosal thickness H2, and the determination method of the second nasal mucosal thickness H2 is shown in expression (4):

[0055]

[0056] In expression (4), H2 is the second nasal mucosal thickness, H 21 ,H 22 ,H 23 ……H 2n is the postoperative mucosal thickness at each position, f 21 ,f 22 ,f 23 ……f 2n is the weight corresponding to each postoperative mucosal thickness; n is the number of postoperative mucosal thicknesses, and n is an integer greater than or equal to 1.

[0057] The result evaluation module 140 is used to determine the treatment result according to the first nasal mucosal thickness, the first nasal mucosal volume, the second nasal mucosal thickness, and the second nasal mucosal volume.

[0058] In an embodiment of the present invention, the result evaluation module 140 includes: a mucosal thickness change ratio determination unit, configured to determine the mucosal thickness change ratio based on the first nasal mucosal thickness and the second nasal mucosal thickness; a mucosal volume change ratio determination unit, configured to determine the mucosal volume change ratio based on the first nasal mucosal volume and the second nasal mucosal volume; and a result determination unit, configured to determine the treatment result according to the mucosal thickness change ratio and the mucosal volume change ratio. Among them, the mucosal thickness change ratio determination unit determines the mucosal thickness change ratio relative to the first nasal mucosal thickness H1 through the first nasal mucosal thickness H1 and the second nasal mucosal thickness H2; similarly, the mucosal volume change ratio determination unit determines the mucosal volume change ratio relative to the first nasal mucosal volume V1 through the first nasal mucosal volume V1 and the second nasal mucosal volume V2; the result determination unit determines the treatment result of ultrasonic treatment of rhinitis based on the mucosal thickness change ratio during (after) surgery relative to before surgery and the mucosal volume change ratio during (after) surgery relative to before surgery.

[0059] In an embodiment of the present invention, the mucosal thickness change ratio determination unit includes: a mucosal thickness change subunit, configured to calculate the difference between the first nasal mucosal thickness and the second nasal mucosal thickness to obtain the mucosal thickness change amount; and a mucosal thickness change ratio calculation subunit, configured to perform a ratio calculation on the mucosal thickness change amount and the first nasal mucosal thickness to obtain the mucosal thickness change ratio. It should be emphasized that if the first nasal mucosal thickness is H1 and the second nasal mucosal thickness is H2, the mucosal thickness change subunit calculates the difference between the first nasal mucosal thickness H1 and the second nasal mucosal thickness H2 to obtain the mucosal thickness change amount (H1 - H2) of the nasal cavity, and the mucosal thickness change ratio calculation subunit performs a ratio calculation on the mucosal thickness change amount (H1 - H2) of the nasal cavity and the first nasal mucosal thickness H1 to obtain the mucosal thickness change ratio Th relative to the first nasal mucosal thickness H1.

[0060] The determination method of the mucosal thickness change ratio Th is shown in Expression (5):

[0064] The determination method of the mucosal volume change ratio Tv is shown in Expression (6):

[0065] Tv = (V1 - V2) / V1 (6)

[0066] In Expression (6), Tv is the mucosal volume change ratio, V1 is the first nasal mucosal volume, and V2 is the second nasal mucosal volume.

[0067] In one embodiment of the present invention, the result determination unit includes: a first result determination subunit for determining that the treatment result is an effective treatment when the mucosal thickness change ratio is less than the preset mucosal thickness change ratio threshold and the mucosal volume change ratio is greater than the preset mucosal volume change ratio threshold; a second result determination subunit for determining that the treatment result is an ineffective treatment when the mucosal thickness change ratio is greater than or equal to the preset mucosal thickness change ratio threshold, or the mucosal volume change ratio is less than or equal to the preset mucosal volume change ratio threshold. It should be noted that the result determination unit includes: the first result determination subunit determines the preset mucosal thickness change ratio threshold and the preset mucosal volume change ratio threshold according to historical cases, compares the mucosal thickness change ratio with the preset mucosal thickness change ratio threshold, and at the same time the second result determination subunit compares the mucosal volume change ratio with the preset mucosal volume change ratio threshold. If the comparison result of the first result determination subunit is that the mucosal thickness change ratio is less than the preset mucosal thickness change ratio threshold and the mucosal volume change ratio is greater than the preset mucosal volume change ratio threshold, it is determined that the treatment result of ultrasonic treatment of rhinitis is an effective treatment; if the comparison result of the second result determination subunit is that the mucosal thickness change ratio is greater than or equal to the preset mucosal thickness change ratio threshold, or the mucosal volume change ratio is less than or equal to the preset mucosal volume change ratio threshold, it is determined that the treatment result of ultrasonic treatment of rhinitis is an ineffective treatment.

[0068] Please refer toFigure 4 , Figure 4 is a flowchart of a method for evaluating the results of ultrasonic treatment of rhinitis shown in an exemplary embodiment of the present invention. As Figure 4 shown, in another exemplary embodiment, a method for evaluating the results of ultrasonic treatment of rhinitis is further provided, which at least includes steps S410 to S440, and is introduced in detail as follows:

[0069] S410. Obtain a first nasal mucosa image and a second nasal mucosa image. The first nasal mucosa image is obtained by sampling the nasal mucosa before ultrasonic rhinitis surgery through an imaging transducer, and the second nasal mucosa image is obtained by sampling the nasal mucosa during or after ultrasonic rhinitis surgery through an imaging transducer;

[0070] S420. Perform point sampling on the first nasal mucosa image to obtain the first nasal mucosa thickness and the first nasal mucosa volume;

[0071] S430. Perform point sampling on the second nasal mucosa image to obtain the second nasal mucosa thickness and the second nasal mucosa volume;

[0072] S440. Determine the treatment result according to the first nasal mucosa thickness, the first nasal mucosa volume, the second nasal mucosa thickness and the second nasal mucosa volume.

[0073] It should be noted that the method for evaluating the results of ultrasonic treatment of rhinitis provided in the above embodiment and the device for evaluating the results of ultrasonic treatment of rhinitis provided in the above embodiment belong to the same concept. The specific ways of performing operations in each step have been described in detail in the loading embodiment, and will not be elaborated here.

[0074] As Figure 2 shown, in another exemplary embodiment, a nasal cavity ultrasonic treatment device is further provided, and the treatment device includes:

[0075] An ultrasonic transducer, on which an imaging transducer and a treatment transducer are provided. The imaging transducer is used to penetrate into the nasal cavity to collect a first nasal mucosa image and a second nasal mucosa image. The first nasal mucosa image is an image of the nasal mucosa before ultrasonic rhinitis surgery, and the second nasal mucosa image is an image of the nasal mucosa during or after ultrasonic rhinitis surgery. The treatment transducer is used to perform ultrasonic treatment on the mucosa inside the nasal cavity;

[0076] The operating end is internally provided with an image processing unit and an evaluation unit. The operating end is connected to the ultrasonic transducer through a connecting rod. The image processing unit is used for performing point sampling on the first nasal mucosa image and the second nasal mucosa image to obtain the first nasal mucosa thickness, the first nasal mucosa volume, the second nasal mucosa thickness, and the second nasal mucosa volume. The evaluation unit is used for determining the treatment result according to the first nasal mucosa thickness, the first nasal mucosa volume, the second nasal mucosa thickness, and the second nasal mucosa volume.

[0077] Specifically, the ultrasonic transducer includes an imaging transducer and a treatment transducer. As Figure 2 shown, when the imaging transducer and the treatment transducer are integrated, the ultrasonic transducer is inserted deep into the nasal cavity. The imaging transducer on the ultrasonic transducer is used to accurately position the nasal mucosa in the nasal cavity, and the image of the nasal mucosa before ultrasonic rhinitis surgery and the image of the nasal mucosa during (after) ultrasonic rhinitis surgery are acquired by means of ultrasonic rotation to obtain the images of the nasal mucosa. At the same time, the nasal mucosa in the nasal cavity is treated by the treatment transducer on the ultrasonic transducer; and the acquired images are transmitted to the operating end through the connecting rod. The image processing unit of the operating end performs point sampling on the images of the nasal mucosa before ultrasonic rhinitis surgery and the images of the nasal mucosa during (after) ultrasonic rhinitis surgery to obtain the first nasal mucosa thickness, the first nasal mucosa volume, the second nasal mucosa thickness, and the second nasal mucosa volume. The first nasal mucosa thickness and the first nasal mucosa volume are the parameters in the nasal cavity before ultrasonic rhinitis surgery, and the second nasal mucosa thickness and the second nasal mucosa volume are the parameters in the nasal cavity during (after) ultrasonic rhinitis surgery. The evaluation unit of the operating end directly judges the result of treating rhinitis by ultrasound through the parameters in the nasal cavity before ultrasonic rhinitis surgery and the parameters in the nasal cavity during (after) ultrasonic rhinitis surgery.

[0078] It should be emphasized that when the imaging transducer and the treatment transducer are separate devices, the imaging transducer is a separate data sampling end, which directly inserts deep into the nasal cavity to sample the nasal mucosa to obtain a sampling image; the treatment transducer is a separate ultrasonic treatment end, which can insert deep into the nasal cavity to treat the nasal mucosa by ultrasound; the operating end is a separate operating device, which can be used for point sampling of the mucosal images before and after (during) treatment in the nasal cavity and evaluating the treatment result according to the sampled data.

[0079] In an embodiment of the present invention, the operating end is connected to the display terminal through a transmission line, and the display terminal is used for displaying the nasal cavity image. As Figure 2 shown, the nasal cavity image of the operating end can be displayed on the display terminal.

[0080] The present application provides an evaluation device, method and nasal cavity ultrasonic treatment device for the results of ultrasonic treatment of rhinitis. The device includes: obtaining a first nasal mucosa image and a second nasal mucosa image through an acquisition module. The nasal mucosa images are acquired by an imaging transducer. The first nasal mucosa image is the image before ultrasonic rhinitis surgery, and the second nasal mucosa image is the image during or after ultrasonic rhinitis surgery; performing point collection on the first nasal mucosa image through a first image processing module to obtain the thickness and volume of the first nasal mucosa, and performing point sampling on the second nasal mucosa image through a second image processing module to obtain the thickness and volume of the second nasal mucosa, and determining the treatment result according to the thickness and volume of the first nasal mucosa, the thickness and volume of the second nasal mucosa. The present application obtains the thickness and volume of the nasal mucosa before and during (after) treatment through an imaging transducer to evaluate the treatment effect, provides a reference basis for the staff, avoids the situation of repeated treatment, and improves the treatment experience of patients.

[0081] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
