Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and in particular relates to a treatment head and a photodynamic therapy device for cervical and vaginal wall lesions. Background Art

[0002] Human papillomavirus (HPV) is a double-stranded circular DNA virus. HPV infection is highly epithelial-tropic, selectively infecting only skin and mucosal epithelial cells. It has been established internationally that persistent infection with high-risk HPV is the main cause of precancerous lesions of the lower genital tract (including the cervix, vagina, and vulva) and malignant tumors, while low-risk HPV can cause genital warts and other benign lesions.

[0003] Currently, red light irradiation is an effective treatment for HPV and precancerous lesions of the lower reproductive tract. It irradiates the local lesion site, and the affected area absorbs light energy and transfers the energy to the surrounding oxygen molecules, generating singlet oxygen, oxygen free radicals and other active oxygen substances. Through oxidative damage, it destroys the structure and function of the organelles of the diseased tissue, causes apoptosis and necrosis of the diseased cells, and achieves the treatment purpose.

[0004] For example, publication number CN117717715A discloses an HPV red light therapy device for cervical and vaginal wall lesions, comprising a shell, a accommodating cavity; a light-emitting component for emitting therapeutic light, the light-emitting component comprising a substrate and a light-emitting chip arranged on the substrate; and a rotating component arranged in the accommodating cavity, the rotating component comprising a speed regulator and a motor, the speed regulator being electrically connected to the motor, one end of the motor being fixedly connected to the shell, and the other end being fixedly connected to the light-emitting component, the motor being used to drive the light-emitting component to rotate relative to the shell.

[0005] During actual use of the above solution, the treatment head is inserted into the patient's vagina. The light emitted by the light-emitting chip when it is powered on can only treat the cervix and cannot target and irradiate other parts, including the vaginal vault, vaginal wall, vulva, etc. Summary of the Invention

[0022] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0023] A fixed connection is a connection in which parts or components are fixed without any relative movement. There are two types of connections: detachable and non-detachable.

[0024] (1) A removable connection is a method of fastening components together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0025] (2) Non-detachable connections mainly refer to welding, riveting, and tenoning. Since they require forging, sawing, or oxygen cutting to disassemble during repair or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to workmanship quality, technical inspection, and remedial measures (such as calibration, polishing, etc.).

[0026] A threaded connection refers to a detachable connection in which the connected parts are connected together using a threaded part (or the threaded part of the connected parts).

[0027] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0028] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0029] Beneficial effects of the present invention:

[0030] 1. In the present invention, the entire treatment head is installed on the treatment instrument by connecting the first connecting sleeve to the treatment instrument. In the initial stage, the first connecting sleeve, the second connecting sleeve and the third connecting sleeve are adjusted to be in the same straight line, the second connecting sleeve and the third connecting sleeve are inserted into the patient's vagina, and the red light LED lamp is turned on. The light emitted by the red light LED lamp is irradiated on the patient's cervix to achieve treatment of the lesion position of the patient's cervix. The third connecting sleeve is rotated so that the third connecting sleeve is at right angles to the second connecting sleeve, and the second connecting sleeve is rotated to drive the third connecting sleeve to rotate, so that the third connecting sleeve is aligned with the lesion position on the patient's vaginal wall. The light emitted by the red light LED lamp is irradiated on the patient's vaginal wall to achieve treatment of the lesion position of the patient's vaginal wall.

[0031] 2. In the present invention, since the lesion position and size of the patient's vaginal wall are different, in order to make the light irradiated by the red light LED lamp just cover the lesion position, the second ring disk can be rotated to make the second slider slide in the second slide groove, and the direction of the first slider is guided by the first slider, so that the several blades gather toward the middle or disperse toward the outside in a circular shape, so that the size of the aperture formed between the several blades can be adjusted, and then the size of the light spot emitted by the red light LED lamp can be adjusted.

[0045] The connecting assembly 1 includes a first connecting sleeve 11, one end of which is used for detachable connection with the therapeutic device;

[0046] The rotating assembly 2 includes a second connecting sleeve 21, one end of which is rotatably connected to the other end of the first connecting sleeve 11, so that the second connecting sleeve 21 can rotate around its own axis;

[0047] The treatment component 3 includes a third connecting sleeve 31, one end of the third connecting sleeve 31 is rotatably connected to the other end of the second connecting sleeve 21, so that the third connecting sleeve 31 can swing around the end of the second connecting sleeve 21, and a red light LED lamp 32 is fixedly connected to the interior of the third connecting sleeve 31, and the other end of the third connecting sleeve 31 is fixedly connected to the aperture adjustment mechanism 4.

[0048] During use, the first connecting sleeve 11 is connected to the therapeutic instrument so that the entire treatment head is installed on the therapeutic instrument. In the initial stage, the first connecting sleeve 11, the second connecting sleeve 21 and the third connecting sleeve 31 are adjusted to be in the same straight line, the second connecting sleeve 21 and the third connecting sleeve 31 are inserted into the patient's vagina, and the red light LED lamp 32 is turned on. The light emitted by the red light LED lamp 32 is irradiated on the patient's cervix to achieve treatment of the patient's cervical lesion position. The third connecting sleeve 31 is rotated so that the third connecting sleeve 31 is at right angles to the second connecting sleeve 21, and the second connecting sleeve 21 is rotated to drive the third connecting sleeve 31 to rotate so that the third connecting sleeve 31 is aligned with the position of the lesion on the patient's vaginal wall. The light emitted by the red light LED lamp 32 is irradiated on the patient's vaginal wall to achieve treatment of the patient's vaginal wall lesion position. At the same time, the aperture size of the aperture adjustment mechanism 4 can be adjusted so that the transmitted light spot is the same size as the lesion, which is beneficial to the treatment of the patient's vaginal wall lesions.

[0049] In one embodiment of the present invention, a connecting portion 111 is provided on one end of the first connecting sleeve 11, distal from the second connecting sleeve 21. External threads 112 are provided around the connecting portion 111 for detachable connection to the therapeutic device. During use, the entire treatment head can be mounted on the therapeutic device via external threads 112 on the connecting portion 111.

[0050] In one embodiment of the present invention, a rotating portion 211 is provided on one end of the second connecting sleeve 21 near the first connecting sleeve 11. The rotating portion 211 is rotatably connected to the first connecting sleeve 11. A first annular rack 22 is fixedly connected to the interior of the rotating portion 211. The teeth of the inner ring of the first annular rack 22 are meshed with a first gear 23. The first gear 23 is fixedly connected to the output end of a first motor 24, which is fixedly connected to the inner wall of the first connecting sleeve 11.

[0051] In one embodiment of the present invention, symmetrically arranged first rods 212 are fixedly connected to both sides of the second connecting sleeve 21 near one end of the third connecting sleeve 31. Symmetrically arranged second rods 311 are fixedly connected to both sides of the third connecting sleeve 31 near one end of the second connecting sleeve 21. The first rods 212 and the second rods 311 are rotationally connected. A second motor 33 is fixedly connected to the inner wall of the first rod 212. The output end of the second motor 33 passes through the first rod 212 and is fixedly connected to the second rod 311. During use, the second motor 33 drives the second rod 311 to rotate, which in turn drives the third connecting sleeve 31 to rotate, so that the third connecting sleeve 31 and the second connecting sleeve 21 are at a 90-degree angle, which facilitates the light emitted by the red light LED lamp 32 to align with the lesion on the vaginal wall for irradiation and treatment.

[0052] In one embodiment of the present invention, a bellows-type expansion sleeve 5 is fixedly connected between the second connecting sleeve 21 and the third connecting sleeve 31, such that the first support rod 212 and the second support rod 311 are both sheathed within the bellows-type expansion sleeve 5. During use, when the third connecting sleeve 31 rotates relative to the second connecting sleeve 21, the bellows-type expansion sleeve 5 deforms, thereby protecting the patient's vaginal wall and preventing the second connecting sleeve 21 and the third connecting sleeve 31 from pinching the patient's vaginal wall.

[0053] In one embodiment of the present invention, a fixing bracket 34 is fixedly connected to the interior of the third connecting sleeve 31. A red LED lamp 32 is fixedly connected to the fixing bracket 34. The red LED lamp 32 is positioned on the axis of the third connecting sleeve 31. A wire 35 is electrically connected to the red LED lamp 32, and the other end of the wire 35 is electrically connected to a connector 36. During use, the connector 36 can be connected to an external power source to power the red LED lamp 32. The red LED lamp 32 is positioned on the axis of the third connecting sleeve 31, so that the light emitted by the red LED lamp 32 is located in the center of the aperture, facilitating better irradiation and treatment of the lesion.

[0054] In one embodiment of the present invention, the aperture adjustment mechanism 4 includes a first circular disk 41 and a second circular disk 42, and the first circular disk 41 and the second circular disk 42 are coaxially arranged. The first circular disk 41 is fixedly connected to the inner wall of the third connecting sleeve 31, and a plurality of blades 43 are arranged between the first circular disk 41 and the second circular disk 42. The plurality of blades 43 are evenly distributed along the circumference of the first circular disk 41 and the second circular disk 42. The two sides of the blades 43 are fixedly connected to the first slider 431 and the second slider 432. The first circular disk 41 is provided with a first sliding groove 411 along its circumference, which is the same as the number of blades 43 and is evenly distributed. The first slider 431 is slidably connected in the first sliding groove 411, and the second circular disk 42 is provided with a second sliding groove 421 along its circumference, which is the same as the number of blades 43 and is evenly distributed. The second slider 432 is slidably connected in the second sliding groove 421. During use, since the lesion location and size of the patient's vaginal wall are different, in order to ensure that the light emitted by the red light LED lamp 32 covers the lesion location exactly, the second annular disk 42 can be rotated to make the second slider 432 slide in the second slide groove 421, and the direction of the first slider 43 is guided by the first slider 431, so that the several blades 43 gather in the middle or disperse outward in a circular shape, so that the size of the aperture formed between the several blades 43 can be adjusted, and then the size of the light spot emitted by the red light LED lamp 32 can be adjusted.

[0055] In one embodiment of the present invention, a second annular rack 44 is fixedly connected to the outer side of the second annular disk 42. The second annular rack 44 is coaxially arranged with the second annular disk 42. The inner ring of the second annular rack 44 is meshed with the teeth of the second gear 45. The second gear 45 is fixedly connected to the output end of the third motor 46, and the third motor 46 is fixedly connected to the inner wall of the third connecting sleeve 31. During use, the third motor 46 drives the second gear 45 to rotate, and the second gear 45 drives the second annular rack 44 to rotate. The second annular rack 44 drives the second annular disk 42 to rotate. The rotation of the second annular disk 42 causes the second slider 432 to slide within the second slide groove 421. The first slider 431 guides the direction of the first slider 43, causing the multiple blades 43 to gather in the middle or disperse outward in a circular shape. The size of the aperture formed between the multiple blades 43 is adjustable, and the size of the light spot emitted by the red light LED lamp 32 can be adjusted.
