Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a treatment head for photodynamic therapy of cervical lesions. Background Art

[0002] Cervical cancer is the sixth most common malignant tumor in women. Cervical intraepithelial neoplasia is the precancerous lesion of cervical cancer, which is caused by the infection of high-risk human papillomavirus (HPV). The treatment methods for the infection of cervical cancer virus HPV include drug treatment, physical treatment, surgical treatment, etc. As a new treatment method for cervical lesions, photodynamic therapy uses special photosensitizers and light sources such as lasers to cause chemical reactions in the diseased cervical tissue to destroy the diseased tissue. Compared with the traditional surgical treatment method, photodynamic therapy has the advantages of minimally invasive, low invasiveness, and no scars. Since cervical lesions and cervical cancer are prone to occur in the inner wall of the cervix, the external orifice of the cervix, and the cervical fornix, especially there are a large number of skin folds in the cervical fornix. Usually, the cervical fornix is in a closed state, and it is difficult for the light emitted by the light source to reach, so the photodynamic effect is not very ideal.

[0003] In addition, as disclosed in a Chinese patent for a photodynamic therapy device for early cervical and vaginal cancers and precancerous lesions, with the application number 202011295666.6, although it takes into account the influence of cervical folds on the treatment effect and designs an airbag-type light-emitting structure, effectively solving the problem of the closed cervical fornix, in actual use, it does not consider that the light irradiation is likely to cause the skin temperature at the cervix to rise, exceeding the tolerance of the human body, resulting in poor comfort for the patient. Moreover, the light source enters the body through the insertion tube, and the light emitted by the light source needs to pass through multiple tube walls to reach the cervical lesion, resulting in large loss and poor clarity, affecting the treatment effect. Therefore, a treatment head for photodynamic therapy of cervical lesions is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a treatment head for photodynamic therapy of cervical lesions. Through the first support bladder and the second support bladder provided, the cervical fornix can be effectively opened, so that the folds at the cervical fornix are completely exposed to the light, which is beneficial to thorough treatment. The heat generated during the treatment process can be dissipated in time through the cooling component, reducing the discomfort of the patient during the treatment process and ensuring the treatment comfort of the patient.

[0023] Embodiment 1

[0024] Please refer to Figures 1 to 4 , the present invention preferably provides a technical solution: a treatment head for photodynamic therapy of cervical lesions, including: a medical plastic tube 111, the medical plastic tube 111 is in the shape of a hollow cylinder, an LED lighting component embedded in the wall of the medical plastic tube 111 for illuminating the cervix; and a light treatment component placed in the middle of the lumen of the medical plastic tube 111 for treating the cervix; further including a first support bladder 211 and a second support bladder 212 attached to the outer side of the wall of the medical plastic tube 111, wherein the first support bladder 211 and the second support bladder 212 communicate with each other and are distributed front and back; and a cooling component, the cooling component includes a water inlet pipe 311 and a water outlet pipe 312, the water inlet pipe 311 and the water outlet pipe 312 are respectively arranged on both sides of the wall of the medical plastic tube 111, wherein one end of the water inlet pipe 311 extends into the first support bladder 211 for injecting water, one end of the water outlet pipe 312 penetrates through the first support bladder 211 and extends into the water outlet pipe 312 and is provided with a regulating ball valve 313, when the first support bladder 211 expands to a certain extent, the regulating ball valve 313 is used for draining water; further including a cooling circulation system, the cooling circulation system is connected to the other ends of the first support bladder 211 and the dial layer 213.

[0025] In this embodiment, in combination with Figure 1 , 2, the medical plastic tube 111 is generally in the shape of a hollow cylinder so that the medical plastic tube 111 can extend deep into the vagina to the position of the cervical orifice;

[0026] The first support bladder 211 and the second support bladder 212 attached to the outer side of its tube wall are used for expanding and supporting the cervix. The LED lighting component built into its tube wall is used for illuminating the cervical lesion. At the same time, the retractable light treatment component in its lumen is used for treating the cervical lesion, and the cooling component can timely conduct away the heat generated during the treatment process through water circulation, so as to realize the photodynamic treatment process of the cervix;

[0027] The design highlights of this application are as follows:

[0028] First, the first support bladder 211 and the second support bladder 212 arranged in sequence before and after on the outer side of the tube wall of the medical plastic tube 111 can effectively open the cervical fornix, making the folds at the cervical fornix completely exposed to the light, which is beneficial to the thoroughness of the treatment;

[0029] Second, the LED lighting component can penetrate deep into the human body along with the medical plastic tube 111, making the best use of the LED light and ensuring that the LED light is more evenly distributed in the diseased area;

[0030] Third, the set cooling component can timely conduct away the heat generated during the photodynamic treatment process, reduce the discomfort of the patient during the treatment process, and ensure the treatment comfort of the patient;

[0031] The cooling component is specifically combined with Figure 1 , 2 As shown, one ends of the water inlet pipe 311 and the water outlet pipe 312 respectively extend into the interiors of the first support bladder 211 and the second support bladder 212 to play a role in the water injection and drainage processes of the first support bladder 211 and the second support bladder 212. The other ends of the two can be connected to the cooling circulation system to realize the circulation process of the cooling water. Due to the differences in the constitutions of patients, under the action of the regulating ball valve 313 and the cooling circulation system, the water inlet pipe 311 and the water outlet pipe 312 can realize the adjustment of the bulging degree of the water inlet pipe 311 and the water outlet pipe 312;

[0032] In this invention, by setting the first support bladder 211 and the second support bladder 212, the cervical fornix can be effectively opened, making the folds at the cervical fornix completely exposed to the light, which is beneficial to the thoroughness of the treatment. The heat generated during the treatment process can be timely conducted away by the cooling component, reducing the discomfort of the patient during the treatment process and ensuring the treatment comfort of the patient. At the same time, the LED lighting component makes the best use of the LED light, ensuring that the LED light is more evenly distributed in the diseased area, fully illuminating the diseased area, and then enabling the movable light treatment component to accurately treat the diseased area with good treatment effects.

[0033] Further, the cooling circulation system includes a water chiller 314, a first connecting pipe 316 and a second connecting pipe 315 respectively arranged at the inlet and outlet of the water chiller 314, and the first connecting pipe 316 and the second connecting pipe 315 are respectively connected to the ends of the water outlet pipe 312 and the water inlet pipe 311; it further includes a compressor 317 externally connected to the water chiller 314 for controlling the water pressure of the cooling component; further, the regulating ball valve 313 includes a cross 3131 and a valve sleeve 3132 respectively arranged inside the inlet of the water outlet pipe 312, wherein a spring 3134 is arranged on the cross 3131, and the ball valve body 3133 connected to the end away from the cross 3131 is in sealed butt joint with the valve sleeve 3132; and a first electromagnet 3135 and a second electromagnet 3136 are respectively arranged on the cross 3131 and the ball valve body 3133, and the first electromagnet 3135 and the second electromagnet 3136 repel each other magnetically; it further includes an elastic sac arranged between the ball valve body 3133 and the cross 3131 for sealing and wrapping the spring 3134, the first electromagnet 3135 and the second electromagnet 3136.

[0034] Here, the water chiller 314 and the compressor 317 are respectively used for cooling water and regulating the water pressure and flow rate, and the compressor 317 and the regulating ball valve 313, as the structures for regulating the internal water pressure of the first support sac 211 and the second support sac 212, can adjust the expansion degree of the first support sac 211 and the first support sac 211.

[0035] Specific combination Figure 2 、 3 As shown in the figure, when the trigger point of the regulating ball valve 313 is set as M and the preset bulging degree of the first support sac 211 and the second support sac 212 is Q, at this time, the compressor 317 controls a certain water pressure and flow rate until the water pressure in the first support sac 211 is the same as M, and the first support sac 211 and the second support sac 212 reach the expansion degree of Q. With the end of the treatment, when the water pressure driven by the compressor 317 exceeds the value of M, the ball valve body 3133 of the regulating ball valve 313 is separated from the valve sleeve 3132, and the water inlet of the water outlet pipe 312 is in an open state for drainage.

[0036] It should be noted that the trigger point M of the regulating ball valve 313 is the added value of the elastic coefficient of the spring 3134 and the magnetic force of the first electromagnet 3135 and the second electromagnet 3136. Therefore, by adjusting the magnetic force of the first electromagnet 3135 and the second electromagnet 3136, that is, the current between the two, the bulging degree of the first support sac 211 and the second support sac 212 can be preset.

[0037] Further, an elastic flap layer 213 is arranged on the inner wall of the first support sac 211, in combination with Figure 4As shown, since there are a large number of skin wrinkles at the cervical vault, and the cervical vault is usually in a closed state, in order to ensure the expansion effect of the first support bag 211, when the first support bag 211 is expanded by water pressure and a certain flow rate, the paddle layer 213 can expand to a certain extent to further open the wrinkles at the cervical vault.

[0038] Furthermore, the inner wall of the first support sac 211 is thinner than the inner wall of the second support sac 212. This design enables the first support sac 211 to have a larger expansion volume, making it easier to expand the cervical vault.

[0039] Furthermore, the medical plastic tube 111 is made of a highly transparent material as a whole, with high hardness, and a layer of soft medical silicone material is attached to the front end thereof.

[0040] Combination Figure 1 , 2 The medical plastic tube 111 is in the shape of a hollow cylinder, with a layer of soft medical silicone material attached to its front end to ensure that the medical plastic tube 111 gently touches human tissue when entering the human body; the high transparency of the medical plastic tube 111 reduces the penetration loss of light; at the same time, the medical plastic tube 111 has the characteristics of hardness and anti-bending, which plays a supporting role.

[0041] Furthermore, a waterproof layer is provided between the medical plastic tube 111 and the first supporting bladder 211 and the second supporting bladder 212 .

[0042] Combination Figure 1 , so that the cavities where the first supporting capsule 211 and the second supporting capsule 212 are located are well sealed with the wall of the medical plastic tube 111 to prevent water from seeping out.

[0043] Example 2

[0044] As another embodiment of the present invention, the LED lighting assembly includes a mounting groove 411 opened on the wall of the medical plastic tube 111, and a flexible LED light strip 412 embedded in the mounting groove 411, and the light emitted by the flexible LED light strip 412 is directly facing the cervical diseased tissue along the radial direction of the medical plastic tube 111; it also includes a plurality of LED light-emitting chips added to the flexible LED light strip 412, wherein the LED light-emitting chips arranged at one end of the flexible LED light strip 412 close to the first support capsule 211 are more than the LED light-emitting chips arranged on the flexible LED light strip 412 corresponding to the second support capsule 212.

[0045] In this embodiment, combined Figure 1 , 2As shown, the light emitted by the flexible LED light strip 412 is directed toward the cervical diseased tissue along the radial direction of the medical plastic tube 111 to ensure the lighting treatment effect. In order to improve the lighting effect of the flexible LED light strip 412, dozens to hundreds of LED light-emitting chips are arranged thereon. A large number of them are arranged near the first support bag 211 to save light energy while ensuring the lighting effect of the cervical lesions. The flexible LED light strip 412 is connected to an external power supply.

[0046] Example 3

[0047] As other embodiments of the present invention, the light therapy component includes a long handle 711 that can penetrate the medical plastic tube 111, and a miniature camera 712 embedded in the front end of the long handle 711; it also includes a control panel 713 externally connected to the rear end of the long handle 711, which is used to adjust the current of the first electromagnetic block 3135, the second electromagnetic block 3136 and the flexible LED light strip 412. Furthermore, a channel is also opened inside the long handle 711 to facilitate the external connection of a 630nm laser fiber 511 and a side-transmitting optical fiber 512 set at the front end of the 630nm laser fiber 511.

[0048] The long handle 711 is placed in the lumen of the medical plastic tube 111 and can easily enter the human body through the lumen of the medical plastic tube 111. The miniature camera 712 embedded at one end of the long handle 711 serves as an observation guide when the long handle 711 enters the body through the medical plastic tube 111, which is helpful for accurately finding the cervical opening. The channel set inside the long handle 711 facilitates the external 630nm laser fiber 511 to enter the human body through this channel. The 630nm laser is mainly used to treat the inner wall of the cervix. The control panel 713 and the 630nm laser fiber are both existing mature technologies.

[0049] The specific operation process of the present invention;

[0050] First, the vagina is stretched open with vaginal forceps, and the transparent medical plastic tube 111 is inserted into the cervical opening along the vagina. Then, the magnetic force of the ball valve body 3133 and the valve sleeve 3132 is preset through the control panel 713, and then the water cooler 314 is turned on to set the water pressure and flow rate, so that the cooling water enters the first support bag 211 and the second support bag 212 along the second connecting pipe 315 and the water inlet pipe 311. The cavities of the first support bag 211 and the second support bag 212 expand under certain water pressure and water speed conditions, so as to stretch the cervical vault and the external cervical opening.

[0051] Then, insert the long handle 711 into the human body along the lumen of the medical plastic tube 111. During the operation, it is necessary to observe the internal situation of the human body in real time through the micro camera 712 on the long handle 711 to accurately know the position of the cervical os. At the same time, insert the 630nm laser optical fiber 511 into the inner wall of the cervix 2 - 3 cm through the built-in channel of the long handle 711.

[0052] Finally, turn on the flexible LED light strip 412 and the 630nm laser optical fiber 511 so that the light emitted by the LED and the 630nm laser optical fiber 511 irradiates the cervical lesion. During the treatment process, adjust the water temperature and pressure of the water cooler 314 in real time according to the comfort of the human body.
