Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic imaging technology for tongue movement in the study of pronunciation mechanism, and specifically to a suspension-type ultrasonic scanning probe fixing bracket. Background Art

[0002] The pronunciation system of speech includes aspects such as articulation and phonation. Among them, articulation is used to represent the sounds produced by combining organs such as the tongue, palate, lips, and teeth in the oral cavity. With the continuous development of computer vision technology, researchers hope to provide sufficient visual feedback for the study of pronunciation mechanism by using a visual method.

[0003] Generally, researchers use ultrasonic imaging technology (that is, by holding an ultrasonic imaging probe against the lower jaw) to study the changes in the tongue movement trajectory during pronunciation and the correlation between related tissues. However, in the actual operation process, affected by subjective factors and external factors, the imaging probe often shows phenomena such as sinking (coronal plane), rotation (transverse plane), and tilting (median sagittal plane). The above phenomena lead to errors in trajectory imaging (including: deformation of the tongue movement trajectory and ectopia of the imaging contour). In order to minimize the above errors as much as possible, it should be ensured that the Euclidean distance between the lip margin of the experimenter (data sampler) and the table edge (where the audio acquisition device is deployed) and the Euclidean distance between the ultrasonic scanning probe and the table edge remain relatively unchanged. At the same time, it should be ensured that the gelatin part (ultrasonic beam emitter) on the upper part of the ultrasonic scanning probe is aligned with the central axis of the human face and that the imaging plane always coincides with the median sagittal plane of the head.

[0004] In order to minimize the result error caused by unstable imaging as much as possible, a common imaging stabilization method is that researchers collect data by placing the head on a fixed backrest or fixed bracket, setting the ultrasonic imaging probe on a bracket directly below the lower jaw, and setting the microphone on a microphone bracket directly in front. Although the above method can reduce errors to a certain extent. However, problems such as poor comfort, low flexibility, and large equipment footprint make it difficult for users to cooperate with experiments, data collection, and scientific modeling (3D model) activities for a long time. In addition, with the in-depth study, researchers hope to ensure that the relative distance between the wearer's lower jaw and the ultrasonic scanning probe remains unchanged, and at the same time, hope to qualitatively and quantitatively analyze and study the influence degree of the change in the scanning angle on the ultrasonic imaging result, so as to provide more visual feedback for the in-depth study of the articulation mechanism. To solve the above problems, the present application proposes a suspension-type ultrasonic scanning probe fixing bracket. Summary of the Invention

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a suspension-type ultrasonic scanning probe fixing bracket, which can preferably ensure that the distance between the wearer's mandible and the ultrasonic scanning probe remains at a relatively constant position during the speaker's pronunciation process, thereby minimizing the errors in the trajectory imaging results caused by phenomena such as probe sinking (coronal plane), rotation (transverse plane), and tilt (midsagittal plane); and the wearer can adjust the wearing tightness according to his own needs to ensure wearing comfort; in addition, the wearer can adjust the probe scanning angle according to needs, and can further study the influence of the above factors on the imaging results; enabling researchers to obtain data more in line with the true pronunciation state and pronunciation habits.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] As Figures 1 - 3 shown, the underhung ultrasonic energy converter fixing bracket includes: a headband perforation groove 1, a mandibular cushion block 2, a fixing support rod 3, an ultrasonic scanning probe fixing cabin 4, and a fixing base 5; two lower fixing rods are vertically arranged on both sides of the fixing base 5, mandibular cushion blocks 2 are respectively arranged at the tops of the two lower fixing rods, and the two mandibular cushion blocks 2 are symmetrical to each other. A headband perforation groove 1 is arranged on the outer side of the mandibular cushion block 2; the ultrasonic scanning probe fixing cabin 4 is arranged at the center position of the upper surface of the fixing base 5;

[0018] Further, the ultrasonic scanning probe fixing cabin 4 includes a probe mounting hole groove 6, an upper fixing cabin top sheet 7, an upper fixing cabin shell 8, a loading cavity 9, an angle adjustment gear shaft hole 10, an angle adjustment gear 11, a lock 12, a compression spring 13, and a lower fixing cabin shell 14; the lock 12 is installed in the lower fixing cabin shell 14, a compression spring 13 is installed between the bottom end of the lock 12 and the inner bottom surface of the lower fixing cabin shell 14, two top branches are respectively arranged on both sides of the top of the lower fixing cabin shell 14, two bottom branches are symmetrically arranged at the bottom of the upper fixing cabin shell 8, and the two bottom branches are inserted and arranged between the two top branches at the top of the lower fixing cabin shell 14; an angle adjustment gear shaft hole 10 is arranged on the bottom branch at the bottom of the upper fixing cabin shell 8, an angle adjustment gear shaft hole 10 is arranged on the top branch at the top of the lower fixing cabin shell 14, and is correspondingly communicated with the angle adjustment gear shaft hole 10 on the bottom branch; the angle adjustment gear 11 is arranged between the two bottom branches, and the wheel shaft of the angle adjustment gear 11 is installed in the angle adjustment gear shaft holes 10 on the top branch and the bottom branch, thus forming the protractor part of the ultrasonic scanning probe fixing cabin 4;

[0019] The upper fixing cabin top sheet 7 is arranged on the top of the upper fixing cabin shell 8. A converter mounting hole groove is opened at the middle position of the upper fixing cabin top sheet 7. The converter mounting hole groove has a special geometric shape and can be used to fix the ultrasonic scanning probe; the inside of the upper fixing cabin shell 8 is a loading cavity 9; the upper fixing cabin top sheet 7, the upper fixing cabin shell 8, and the loading cavity 9 together constitute the loading assembly of the ultrasonic scanning probe fixing cabin 4.

[0020] During use, the user fixes this ultrasonic scanning probe holder on the lower jaw of the head through a strap. The perforated slot 1 of the headband is used to suspend the whole holder directly below the lower jaw (in the vertical direction), and the probe mounting slot 6 is used to fix the ultrasonic scanning probe. The data acquisition direction of the ultrasonic scanning probe during data acquisition is changed by rotating the upper shell 8 of the fixing cabin.

[0021] After the perforated slot 1 of the headband is used, it is used to ensure that the whole holder is suspended directly below the lower jaw (in the vertical direction), so as to ensure that the relative distance between the user's lower jaw and the ultrasonic scanning probe does not change with the distance change during the vocalization process. Since the ultrasonic scanning probe fixing cabin 4 is always located between the two lower jaw pads 2. Therefore, the lower jaw pads 2 can be used to confirm the relative position of the lower jaw.

[0022] The ultrasonic scanning probe fixing cabin 4 can adjust the detection angle of the ultrasonic scanning probe in the midsagittal plane. When the user rotates according to the angle, the angle adjustment gear 11 connected to the bottom end of the upper shell 8 of the fixing cabin makes the lock 12 move downward (in the vertical direction), and the compression spring 13 contracts. At this time, the lock 12 receives an upward (in the vertical direction) thrust. When the angle adjustment is completed, the compression spring 13 returns to its original shape, which will make the lock 12 move upward (in the vertical direction), and finally lock the position of the lock 12, thus completing an angle adjustment.

[0023] The ultrasonic probe with a fixed buckle structure can be pressed into the probe mounting slot 6 by pressing down. The ultrasonic probe is locked at the center position of the top piece 7 at the upper end of the fixing cabin by rotation. Then, rotate the upper shell 8 of the fixing cabin to adjust the detection angle on the probe mounting slot 6. During adjustment, pinch the upper shell 8 of the rotating fixing cabin with fingers and select the rotation direction (clockwise or counterclockwise) for adjustment. After the adjustment is completed, let go to determine the new adjustment direction.

[0024] The design of the present invention can play a certain role in limiting the imaging position of the wearer's head during the process of ensuring ultrasonic imaging data acquisition, that is: ensure that the distance between the wearer's lower jaw and the ultrasonic scanning probe remains in a relatively constant position, so as to minimize the trajectory imaging errors (including: tongue movement trajectory deformation and imaging contour ectopia) caused by phenomena such as probe sinking (coronal plane), rotation (transverse plane) and tilt (midsagittal plane). At the same time, the wearer can adjust the wearing tightness according to his own needs to ensure wearing comfort. In addition, the wearer can adjust the probe scanning angle according to needs, which can further study the influence of the above factors on the imaging results. The above series of designs enable researchers to obtain data that more conforms to the wearer's true pronunciation state and pronunciation habits; at the same time, long-term data acquisition can provide long-term, stable and effective data source information for subsequent data analysis and model establishment.

[0025] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
