[0002] The treatment methods for cavity diseases such as vaginal relaxation and urinary incontinence are mainly divided into non-damaging and damaging treatments. Non-damaging treatment is mainly drug treatment, which is safe but slow in effect and has limited effect on patients with moderate to severe conditions. Damaging treatment is mainly carried out through cavity ultrasound therapy. The treatment process is to invade the treatment rod of the treatment device into the cavity, and then use the laser, radio frequency energy or ultrasonic energy emitted by the treatment rod to treat the cavity wall.

[0003] Currently, treatment wands typically emit energy in a point-based manner, requiring medical staff to constantly adjust the wand's position or direction to cover different treatment areas. However, the treatment surface of the cavity is a circular inner wall, which covers a large area. This point-based emission method results in a lengthy treatment process. Utility Model Content

[0015] In one embodiment, the treatment rod is used to be inserted into the vagina for treatment, and the peripheral side wall of the rod tube is divided into a treatment area and a non-treatment area, and the non-treatment area is used to be arranged in contact with the cavity wall facing the urethra; the cavity ultrasound therapeutic instrument also includes a first sensing element and a second sensing element, and the first sensing element and the second sensing element are respectively arranged on the two side edges of the non-treatment area of ​​the rod tube, and when the first sensing element or the second sensing element senses that a transducer has rotated to be opposite to the non-treatment area, the controller in the cavity ultrasound therapeutic instrument controls the corresponding transducer to stop emitting energy.

[0031] Currently, the energy delivery method of the therapeutic wand in intracavitary ultrasound therapy devices is mostly point-based, requiring medical staff to constantly adjust the position or direction of the therapeutic wand to cover different treatment areas. However, the treatment surface of the intracavitary cavity is a circular inner wall, which has a large treatment area. This point-based delivery method results in a long treatment process.

[0032] To this end, the present invention proposes a cavity ultrasonic therapeutic device 100.

[0033] See also Figures 1 to 4 The embodiment of the present cavity ultrasound therapeutic device 100 includes a handle 1, a therapeutic rod 2 and a transducer module. The therapeutic rod 2 is arranged at one end of the handle 1. The therapeutic rod 2 includes a rod barrel 21 and a support frame 22 arranged in the rod barrel 21. The side wall of the support frame 22 is spaced apart from the inner wall of the rod barrel 21 to form a sound guide cavity. The transducer module includes at least two transducers 3. The transducers 3 are circumferentially arranged on the circumferential side of the support frame 22, and each transducer 3 is extended along the length direction of the support frame 22 to emit a one-dimensional focal line to form a therapeutic thermal damage line extending along the length direction of the cavity at the target depth of the cavity tissue.

[0034] The therapeutic rod 2 in the present intracavitary ultrasound therapeutic device 100 is used for insertion into cavities such as the vagina and urethra for treatment. The handle 1 is used to form a grip portion to facilitate the user's insertion or removal of the therapeutic rod 2. The therapeutic rod 2 includes a rod barrel 21 and a support frame 22 disposed within the rod barrel 21. The support frame 22 is rod-shaped, with a cross-sectional dimension smaller than that of the rod barrel 21, so that a sound-conducting cavity is formed between the side wall of the support frame 22 and the inner wall of the rod barrel 21. The sound-conducting cavity is filled with a liquid sound-conducting medium. The transducer module is immersed in the sound-conducting medium so that ultrasonic waves can be transmitted through the sound-conducting medium. Specifically, the transducer module includes at least two transducers 3. The two or more transducers 3 are arranged circumferentially around the support frame 22, and each transducer 3 is tile-shaped and extends along the length of the support frame 22. As a result, each transducer 3 focuses in the direction it faces, forming a one-dimensional focal line. At the same time, in order to ensure that ultrasonic energy can pass through the rod barrel 21, a sound-permeable opening is opened on the side wall of the rod barrel 21 to form a grid structure, and a sound-permeable membrane is attached to the grid structure to seal the sound-permeable opening thereon, thereby preventing leakage of the sound-conducting medium while allowing ultrasonic energy to be effectively transmitted to the cavity wall 200.

[0035] The present intracavitary ultrasound therapeutic device 100 comprises a plurality of transducers arranged around the periphery of the support frame 22, each capable of emitting a one-dimensional focal line. During treatment, the annular cavity wall can be treated simply by rotating the therapeutic rod 2. Because the one-dimensional focal line has a larger coverage area than point-based focusing, the treatment coverage area along the length of the cavity is increased. Furthermore, the circumferential arrangement of the transducers increases the treatment coverage area perpendicular to the length of the cavity and along the circumferential wall. Furthermore, combined with circumferential rotation, this reduces the number of intracavitary movements of the therapeutic rod, shortening the time required for a single treatment cycle and improving treatment uniformity along the length of the cavity. This overcomes the technical problem of localized overtreatment caused by cavity wrinkles.

[0036] We know that the subcutaneous depths of different tissue layers of the human body are different, and the depths of the same tissue layer in different individuals also vary. In order to improve the flexibility and universality of the focusing depth of the present cavity ultrasound therapeutic device 100, in some embodiments of the present invention, the transducer module includes at least two transducer groups, and the focusing depths of each transducer group are different.

[0037] Each transducer group includes at least one transducer 3, and the transducers 3 in the same transducer group have the same focal depth. In the embodiment shown in the figure, the transducer module includes a first transducer group and a second transducer group. The first transducer group and the second transducer group each include two oppositely disposed transducers 3. The focal depth of the transducers 3 in the first transducer group is greater than the focal depth of the transducers 3 in the second transducer group, thereby achieving ultrasound treatment at two depths.

[0038] Of course, in actual applications, the number of transducer groups is not limited to two, and can be three, four, five, or even more. Furthermore, the number of transducers 3 in each group can be one, two, or three, etc., without limitation, thereby achieving multi-depth treatment. In this case, the support frame 22 is preferably a polyhedron, and each transducer 3 can be mounted on a surface of the support frame 22. Of course, the support frame 22 can also be a cylinder, in which case the transducers 3 can be circumferentially mounted on the circumference of the support frame 22 via a backing bracket.

[0039] Furthermore, the intracavitary ultrasonic therapeutic device 100 also includes a controller (not marked) and a tissue layer depth detection module (not marked). The controller is electrically connected to all transducer groups and the tissue layer depth detection module. The controller is set in the handle 1, and the tissue layer depth detection module is set on the treatment rod 2 for detecting the tissue layer depth of the cavity wall 200. The controller controls the opening and closing of different transducer groups according to the detected tissue layer depth.

[0040] It should be noted that the tissue layer depth detection module includes an ultrasonic transmitter and an ultrasonic receiver, wherein the ultrasonic transmitter is used to transmit ultrasonic waves toward the skin tissue. When the ultrasonic wave encounters the interface between two layers of tissue with different impedances, such as the interface between the epidermis and the dermis, reflection will occur. The reflected ultrasonic signal is received by the ultrasonic receiver and sent to the controller. The controller analyzes the received signal to derive the depth of the tissue layer. Subsequently, the controller selectively activates the transducer group with the appropriate focusing depth according to the detected tissue layer depth, and rotates the treatment to achieve deep and precise treatment.

[0041] One embodiment of the transluminal ultrasound therapeutic device 100 further includes a control button located on the treatment handle 1 and electrically connected to all transducer groups for simultaneously turning all transducer groups on and off. By pressing the control button, transducer groups at multiple focal depths can be simultaneously activated and rotated for treatment, achieving simultaneous multi-depth treatment and enhancing therapeutic efficacy.

[0042] Alternatively, the present intracavitary ultrasonic therapeutic apparatus may be provided with a tissue layer depth detection module and a control button at the same time. In this case, the transducer module has an automatic mode and a manual mode. The so-called automatic mode is to automatically control the opening and closing of different transducer groups through the cooperation between the tissue layer depth detection module and the controller; the so-called manual mode is to manually control the opening and closing of all transducer groups through the control button, thereby improving the flexibility of the treatment mode.

[0043] In one embodiment of the present invention, the transducer module includes a focused transducer and an unfocused transducer, which are arranged circumferentially around the support frame 22. The focused transducer can concentrate ultrasonic energy on a specific line for targeted treatment, while the unfocused transducer has an unconcentrated ultrasonic energy and a wide radiation range, and is used for preheating or enhanced treatment. In this case, the focused transducer can be the first transducer group, and the unfocused transducer can be the second transducer group. The controller can switch between the first transducer group and the second transducer group according to a preset program, or can specifically open and close the first transducer group or the second transducer group through a control button to achieve diversified treatment.

[0044] In one embodiment of the present invention, the transducer module is slidably mounted on the support frame 22, and the sliding direction of the transducer module is the longitudinal direction of the support frame 22. It should be noted that the sliding distance of the sliding module is relatively short, with only slight sliding, which does not affect treatment. The sliding arrangement of the transducer module provides a certain cushioning effect when the treatment rod 2 is inserted into the cavity, thereby reducing direct impact on the cavity wall and protecting sensitive tissue.

[0045] During treatment, the operator can manually rotate the treatment rod 2 to achieve treatment of the entire annular cavity wall 200, but in order to free both hands, the cavity ultrasound therapeutic device 100 can be provided with a rotating mechanism, such as a DC motor or a stepping motor. The rotating mechanism is arranged in the handle 1 and is connected to the treatment rod 2 for driving the support frame 22 to rotate alone or to drive the support frame 22 and the rod barrel 21 to rotate together.

[0046] In one embodiment, a rod barrel 21 is fixedly mounted at one end of the handle 1, and a support frame 22 is rotatably mounted within the rod barrel 21. The rotating shaft of the rotating mechanism passes through the rod barrel 21 and is coaxially connected to the support frame 22. Rotation of the rotating shaft drives the support frame 22, which in turn drives the transducer 3 mounted thereon, thereby rotating the focal line of the transducer 3 and thereby treating the entire annular cavity wall 200. The rod barrel 21 remains stationary, maintaining a close fit with the cavity during the rotational treatment process, thus avoiding the potential for loose contact or uneven pressure caused by manual rotation.

[0047] In one embodiment, the rod barrel 21 and the support frame 22 are relatively fixed, and the rod barrel 21 is rotatably connected to the handle 1, and the rotating shaft of the rotating mechanism is coaxially connected to the rod barrel 21. At this time, the rotation of the rotating shaft will drive the rod barrel 21 and the support frame 22 to rotate together, thereby treating the entire annular cavity wall 200.

[0048] Among them, when the rotation mechanism adopts a stepping motor, the rotation of the focus line is not continuous, but intermittent. At this time, the time for each area to be refocused and covered can be extended, avoiding local overheating of the cavity wall 200, which is conducive to utilizing normal tissue to accelerate healing and shorten recovery time.

[0049] In summary, the present cavity ultrasound therapeutic device 100 can realize the autonomous rotation of the treatment rod 2 by setting a rotation mechanism, so that the one-dimensional focal line of the transducer 3 can cover the entire annular treatment surface, thereby realizing treatment of the entire annular cavity wall 200, reducing the dependence on the operator's skills and greatly improving the treatment efficiency.

[0050] It should be noted that some cavities may only require treatment of a portion of the cavity wall, rather than the entire annular cavity wall. To address this situation, the controller in the present cavity ultrasound therapeutic device 100 is electrically connected to all transducers and is used to control the intermittent on and off of each transducer so that the focal lines of each transducer form a discontinuous treatment surface during rotation. For example, an angle sensor may be provided on the rotating motor to monitor the rotation angle of the rotating motor in real time. When the angle sensor detects that the rotating motor has rotated to a first preset angle, indicating that a transducer has rotated to a non-treatment area, the controller controls the corresponding transducer to stop emitting energy. When the angle sensor detects that the rotating motor has rotated to a second preset angle, the controller controls the transducer to resume emitting energy. Alternatively, each transducer is provided with an angle sensor, and a controller is electrically connected to all the angle sensors to obtain the orientation of each transducer. When a transducer rotates between a first preset direction and a second preset direction, indicating that the transducer has entered a non-treatment zone, the controller controls the transducer to stop emitting energy. When the transducer rotates outside the first and second preset directions, the controller controls the transducer to continue emitting energy. In this case, the treatment zone covered by the transducer's rotation is not a complete annular wall surface, but rather a discontinuous wall surface.

[0051] In one embodiment of the present invention, the treatment rod 2 is used to be inserted into the vagina for treatment. As we know, the vagina is close to the urethra, and the ultrasonic transducer can transmit ultrasonic energy to below the epidermis. If the rotation angle of the transducer module exceeds the range, the ultrasonic energy released will affect the urethra and may cause damage. To avoid this phenomenon, one embodiment of the present intracavitary ultrasonic therapeutic device 100 is provided with a first blocking member (not marked) and a second blocking member (not marked) on the rotation mechanism. The first blocking member and the second blocking member are used to prevent the transducer module from rotating to the opposite side of the urethra. The first blocking member and the second blocking member are used to limit the angle range of the support frame 22 alone or the angle range of the support frame 22 and the rod barrel 21 together, thereby preventing the rotation from exceeding the range and affecting the urethra.

[0052] Alternatively, one embodiment of the present invention divides the circumferential side wall of the rod barrel 21 into a treatment area 211 and a non-treatment area 211. The non-treatment area 211 is used to fit with the cavity wall 200 facing the urethra, and the sound-transmitting openings are all opened on the treatment area 211 to ensure that the ultrasonic energy can only pass through the sound-transmitting membrane of the treatment area 211 and cannot pass through the side wall of the non-treatment area 211, so as to avoid the ultrasonic energy affecting the non-treatment area 211 and ensure the safety of the treatment.

[0053] In one embodiment, the intracavitary ultrasonic therapeutic apparatus 100 further includes a plurality of sensing elements. Each transducer is provided with a sensing element. When the controller detects that a sensing element rotates to face the non-treatment area 212, the controller controls the corresponding transducer to stop emitting energy.

[0054] In another embodiment, the intracavitary ultrasonic therapeutic device 100 further includes a first sensing element and a second sensing element, which are respectively arranged on the two side edges of the non-treatment area of ​​the rod barrel 21. When the first sensing element or the second sensing element senses that a transducer has rotated to the opposite side of the non-treatment area, the controller controls the corresponding transducer to stop emitting energy.

[0055] Among them, the sensing element can be a photosensor. When the photosensor rotates to be opposite to the non-treatment area 211 or opposite to the transducer, the light signal received by the photosensor changes. At this time, the controller can receive the signal sent by the photosensor and then control the corresponding transducer to stop emitting energy.

[0056] Some embodiments of the intracavitary ultrasound therapeutic apparatus 100 further include a focus depth adjustment mechanism, which is in transmission connection with each transducer 3 and is used to adjust the distance between each transducer 3 and the rod barrel 21, thereby adjusting the focus depth of each transducer 3, thereby improving the flexibility and universality of the intracavitary ultrasound therapeutic apparatus 100. The focus depth here refers to the distance from the focal position to the surface of the tissue layer.

[0057] Reference Figure 3 and Figure 4 The support frame 22 includes at least two pairs of opposing side panels 221. Each side panel 221 is separately disposed and encloses a cylindrical structure. A transducer 3 is mounted on one side panel 221, and an elastic member 222, such as a spring, is disposed between the two opposing side panels 221. A focus depth adjustment mechanism is in transmission connection with each side panel 221, configured to drive each side panel 221 toward the rod barrel 21, thereby varying the distance between each transducer 3 and the rod barrel 21 and thereby adjusting the focus depth of the transducer 3.

[0058] Specifically, the focusing depth adjustment mechanism includes a moving part 4 and a driving part (not marked). The moving part 4 is arranged in the rod barrel 21 and is coaxially arranged with the support frame 22. The driving part is connected to the moving part 4 for driving the moving part 4 to move along the axial direction of the support frame 22. The cross-sectional size of the moving part 4 gradually increases from the end away from the handle 1 to the end close to the handle 1. The moving part 4 moves toward the hollow channel of the support frame 22, and can push open the side plate 221 of the support frame 22, thereby changing the focusing depth of the transducer 3.

[0059] In the embodiment shown in the figure, the support frame 22 includes a first side plate, a second side plate, a third side plate, and a fourth side plate that are separately arranged. The four side plates 221 enclose a cylindrical structure. The first side plate and the second side plate are arranged opposite each other, and the third side plate and the fourth side plate are arranged opposite each other. A first elastic member is arranged between the first side plate and the second side plate, and a second elastic member is arranged between the second side plate and the third side plate. The moving member 4 of the focus depth adjustment mechanism is a cone, and its side wall surface is an inclined surface, so that the cross-sectional dimensions of the moving member 4 gradually increase from the end away from the handle 1 to the end close to the handle 1, and the cross-sectional dimensions of the small end surface are smaller than the cross-sectional dimensions of the hollow channel of the support frame 22, and the cross-sectional dimensions of the large end surface are larger than the cross-sectional dimensions of the hollow channel of the support frame 22. When the moving member 4 moves toward the hollow channel of the support frame 22 under the action of the driving member, the moving member 4 can gradually push open the side plates 221 of the support frame 22. When the moving member 4 exits the hollow channel of the support frame 22, the side plates 221 of the support frame 22 are automatically retracted under the pulling force of the elastic member 222, thereby adjusting the focusing depth of the transducer 3. The driving member can be a linear motor, a cylinder, a screw, or a matching structure of a slide rail and a slider, etc. The driving member can be set in the handle 1 to drive the moving member 4 to move, or it can be set on one of the side plates 221 to drive the moving member 4 to move. The position of the driving member can be flexibly set according to actual needs and is not limited here.

[0060] In actual application, the support frame 22 can be a hollow regular tetrahedron, regular hexahedron, regular octahedron, etc. As long as the two opposite side plates are connected by elastic members, the focus depth can be adjusted by moving the moving member 4.

[0061] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
