Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a device for treating HPV cervical lesions. Background Technology

[0002] Persistent infection with high-risk human papillomavirus (HPV) is the core cause of cervical intraepithelial neoplasia (CIN) and cervical cancer. Early intervention of cervical lesions and HPV clearance are key steps in preventing the progression of cervical cancer. In clinical non-surgical treatment of cervical lesions and HPV infection, topical application of anti-HPV gel has become the mainstream intervention method for low-grade cervical lesions and persistent high-risk HPV infection due to its non-invasive nature, preservation of cervical structure and fertility, and high patient compliance.

[0003] Current anti-HPV gels primarily utilize active ingredients such as lactoferrin, interferon, and IGY antibodies to target and block HPV viral replication, thereby reducing viral load. Clinical studies have shown that anti-HPV gels employing targeted delivery technology have a viral inhibition efficiency 3-5 times higher than ordinary gels. Currently, anti-HPV gel administration often uses a pump-type applicator with a soft tube. During use, the injection connector at the tip of the tube must be inserted deep into the vagina and aimed at the cervical lesion to deliver the gel.

[0004] Because the injection connector comes into direct contact with vaginal secretions, mucus, and other bodily fluids during the process of entering the body, the viscous secretions can easily adhere to and block the drug outlet, leading to poor drug delivery and insufficient dosage. In addition, the lesion of the cervix is ​​located deep in the vagina and is a sensitive area. Patients are prone to trembling and shifting their position due to tension and pain reflexes when receiving medication. This directly causes the angle and depth of the injection connector to deviate from the lesion, and the drug cannot accurately cover the cervical transformation zone and lesion area. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide an HPV treatment device for cervical lesions. The problem it aims to solve is that when performing gel injection on cervical cancer patients, the injection connector is prone to contact with vaginal secretions, mucus and other bodily fluids when it enters the body. The viscous secretions are easy to adhere and block the drug outlet, resulting in poor drug delivery and insufficient drug dosage. In addition, the cervix is ​​a sensitive area, and patients are prone to tension and trembling, which can cause the connector angle and depth to deviate, making it impossible for the drug to accurately cover the lesions.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for treating HPV cervical lesions, comprising a device body, wherein an anti-HPV gel storage tank for storing anti-HPV gel is fixedly installed on the device body, the device body and the anti-HPV gel storage tank are respectively connected to an injection connector for injecting anti-HPV gel into the cervical region via an imaging wire, a heating wire and a gel delivery tube, the injection connector comprising an injection module, a protective module for protecting the injection module, and an anti-detachment module for restricting the movement of the protective sleeve at the cervical os; The injection module includes an injection sleeve, in which an injection tube and an imaging hard wire, which are connected to the glue delivery hose and the image lead wire, are fixedly installed respectively.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention discloses an HPV treatment device for cervical lesions. Example

[0023] Reference Figure 1-9This invention provides a first embodiment of an HPV treatment device for cervical lesions. The device includes a treatment body 1, on which an anti-HPV gel storage tank 2 for storing anti-HPV gel is fixedly installed. The treatment body 1 and the anti-HPV gel storage tank 2 are connected to an injection connector for injecting anti-HPV gel into the cervical region via an image guide 11, a heating guide 12, and a gel delivery tube 22. The injection connector includes an injection module 3, on which a protective module 4 is fitted. The protective module 4 is fitted with an anti-detachment module 5 to restrict the movement of the protective sleeve 41 at the cervical os. The injection module 3 includes a gel injection tube 31, in which... An injection tube 32 and an imaging hard wire 33, which are fixedly installed and connected to the glue dispensing hose 22 and the image guide wire 11, are distributed along the axial direction of the glue dispensing sleeve 31. A glue application elbow 321 and an optical imaging unit 331 are fixedly installed at the protruding ends of the injection tube 32 and the imaging hard wire 33, respectively, with the elbow 321 and the optical imaging unit 331 arranged to avoid each other. The optical imaging unit 331 is electrically connected to the image guide wire 11 via the imaging hard wire 33. The protection module 4 includes a protective sleeve 41 distributed along the axial direction of the glue dispensing sleeve 31. The protective sleeve 41 has a bend dustproof groove 412 adapted to the glue application elbow 321. When the glue application elbow 321 is located in the bend dustproof groove 412... The opening of the adhesive-coating elbow 321 is sealed to the inner wall of the protective sleeve 41. The treatment device body 1 is the control core of the entire device, integrating an image processing module, a temperature control module, and a power supply module for imaging display, electrothermal regulation, and overall power supply. The anti-HPV gel storage tank 2 is made of medical-grade sealing material to prevent gel contamination and deterioration. Its volume is adapted to the clinical single-dose dosage, facilitating rapid gel replenishment by medical staff. The image guide 11 is used to transmit cervical lesion images acquired by the optical imaging unit 331. The heating guide 12 is used to transmit electrical energy to the heating element 44. The gel delivery tube 22 is made of flexible medical silicone material, adaptable to the angle of the injection connector, avoiding bending and blockage, and ensuring smooth gel delivery. As the actuator that comes into direct contact with the patient's cervix, the injection module 3 achieves precise drug delivery and protection through the coordinated action of its various modules. The injection cannula 31 of the injection module 3 is a rigid medical tubing that provides installation support for the injection tube 32 and the imaging wire 33, ensuring their fixed positions. The adhesive elbow 321 adopts an arc-shaped structure design, which can conform to the curvature of the cervix, allowing the gel to be evenly applied to the lesion area. The optical imaging unit 331 uses a miniature high-definition camera to acquire images of the cervical lesion area in real time, which are transmitted to the display terminal of the treatment device body 1 through the image guide 11, facilitating medical staff to observe the lesion location and adjust the drug delivery angle. The protective sleeve 41 is used to seal and protect the adhesive elbow 321 and the optical imaging unit 331 during the insertion of the injection connector into the body.The dimensions of the dustproof groove 412 of the elbow are precisely matched with those of the adhesive application elbow 321. Its airtight design effectively isolates vaginal secretions, mucus, and other bodily fluids, preventing these fluids from adhering and clogging the dispensing port of the adhesive application elbow 321.

[0024] The inner diameter of the injection sleeve 31 is matched with the inner diameter of the protective sleeve 41. A water-blocking ring is provided in the gap between the injection sleeve 31 and the protective sleeve 41 for a sealed connection. The end of the injection sleeve 31 away from the glue-applying elbow 321 extends to the outside of the protective sleeve 41 and is fixedly installed with a first piston handle 34. The diameter matching design of the injection sleeve 31 and the protective sleeve 41 can ensure smooth sliding cooperation between the two. The water-blocking ring is made of medical-grade waterproof sealing material, which can achieve complete sealing after being embedded in the gap between the two. The first piston handle 34 is easy for medical staff to hold and operate. By pushing or pulling the first piston handle 34, the injection sleeve 31 can be slid along the axial direction of the protective sleeve 41, thereby adjusting the extension length of the glue-applying elbow 321 and the optical imaging unit 331 to adapt to the cervical depth of different patients and ensure that the glue-applying elbow 321 is accurately aligned with the lesion area.

[0025] The glue-injection sleeve 31 is externally fixed with symmetrically distributed guide protrusions 311. The inner wall of the protective sleeve 41 is provided with guide grooves 411 distributed along its axial direction. The glue-injection sleeve 31 slides along the axial direction of the protective sleeve 41 through the guide protrusions 311 and the guide grooves 411. The guide protrusions 311 can ensure the stability of the glue-injection sleeve 31 when sliding, avoid rotation and displacement, and ensure that the glue-applying elbow 321 and the optical imaging unit 331 always maintain the preset angle. The length of the guide groove 411 is adapted to the sliding stroke of the glue-injection sleeve 31. Its inner wall is smoothed to reduce the friction when the guide protrusions 311 slide. At the same time, it can limit the sliding range of the glue-injection sleeve 31 and avoid excessive sliding that could damage the components or cause damage to the patient's cervix.

[0026] A locking disc 42 is fixedly installed on the outside of the protective sleeve 41, and a guide lock frame 421 is fixedly installed on the locking disc 42. The guide lock frame 421 has a wedge-shaped locking block 4211 that slides radially along the protective sleeve 41. Inside the guide lock frame 421 and at the bottom end of the wedge-shaped locking block 4211, there is a return spring 4212 that is radially distributed along the protective sleeve 41. The two ends of the return spring 4212 are respectively connected to the wedge-shaped locking block 4211 and the outer wall of the protective sleeve 41. The locking disc 42 has a circular structure and is used to install the guide lock. The guide lock frame 421 and the connecting anti-detachment module 5 are sized to fit the protective sleeve 41. The guide lock frame 421 is used to guide and limit the wedge-shaped locking block 4211, ensuring that the wedge-shaped locking block 4211 can only slide radially along the protective sleeve 41. The wedge-shaped surface of the wedge-shaped locking block 4211 faces the ratchet disc 51, which facilitates engagement with the wedge-shaped locking groove 511. The return spring 4212 is made of medical-grade elastic material. When in its natural state, it can push the wedge-shaped locking block 4211 to extend towards the ratchet disc 51, thereby achieving automatic engagement and locking.

[0027] A second piston handle 43, corresponding to the first piston handle 34, is fixedly installed at the end of the protective sleeve 41 away from the elbow dustproof groove 412. The second piston handle 43 is also equipped with an electrode interface 431 electrically connected to the treatment device body 1 via a heating wire 12. An annular array of heating elements 44 is provided at the end of the protective sleeve 41 near the elbow dustproof groove 412. The heating elements 44 are connected to the electrode interface 431 via a wire. The second piston handle 43, like the first piston handle 34, adopts an ergonomic design, facilitating two-handed operation by medical personnel. One hand holds the second piston handle 43 to fix the protective sleeve 41, while the other... The position of the injection sleeve 31 is adjusted by manually pushing the first piston handle 34 to improve operational stability. The electrode interface 431 is a waterproof and sealed interface to prevent short circuits caused by contact with bodily fluids. It is connected to the temperature control module of the treatment device body 1 through the heating wire 12 to realize the temperature regulation of the heating element 44. The heating element 44 is made of ultra-thin medical heating material. The ring array distribution can make the front end of the protective sleeve 41 heat up evenly. On the one hand, it can soften the anti-HPV gel, improve the gel fluidity, and facilitate even application. On the other hand, it can promote local blood circulation in the cervix, enhance the drug absorption effect, and relieve the discomfort caused by cervical sensitivity in patients.

[0028] The anti-dislodgement module 5 includes a ratchet disc 51 rotatably connected to the outside of the locking disc 42. The inner ring of the ratchet disc 51 has a ring array of wedge-shaped locking grooves 511, which are adapted to the wedge-shaped locking blocks 4211. The rotation angle of the ratchet disc 51 can be positioned by the engagement of the wedge-shaped locking blocks 4211 and the wedge-shaped locking grooves 511. The mutual engagement of the wedge-shaped locking grooves 511 and the wedge-shaped locking blocks 4211 can lock the ratchet disc 51 at multiple angles, which is convenient for adjusting the angle of the injection sleeve 31 according to the position of the patient's cervix. The wedge-shaped structure of the wedge-shaped locking grooves 511 can achieve one-way locking after engaging with the wedge-shaped locking blocks 4211, preventing the ratchet disc 51 from rotating in the opposite direction, ensuring the fixation effect of the anti-dislodgement module 5, and further preventing the injection connector from falling off or shifting due to changes in the patient's body position or trembling during drug administration.

[0029] A rubber plug 52 with decreasing diameter is fixedly installed at one end of the ratchet disc 51 near the protective sleeve 41. The rubber plug 52 is also provided with a ring array of silicone sheets 521. One end of the silicone sheet 521 near the rubber plug 52 is smooth, and the other end is rough. The rubber plug 52 is made of medical-grade soft rubber. The decreasing diameter design can adapt to different sizes of vaginal openings, making it easy to insert into the vaginal opening without causing damage to the vagina. At the same time, its softness can conform to the contour of the vagina and enhance the sealing. The silicone sheet 521 is made of medical-grade silicone, which has good biocompatibility and friction. It can evenly conform to the inner wall of the vaginal opening. The smooth surface faces the rubber plug 52, which can reduce the resistance during insertion and avoid damage to the vaginal mucosa. The rough surface faces the inner wall of the vagina, which can increase the friction with the vaginal opening and further improve the anti-dislodgement effect, preventing the injection connector from shifting during the administration of drugs to the cervix.

[0030] A gel metering pump 21 for quantitative injection of anti-HPV gel is fixedly installed on the anti-HPV gel storage tank 2. The output port of the gel metering pump 21 is connected to the injection rigid tube 32 through the gel delivery tubing 22. The gel metering pump 21 adopts a high-precision quantitative control structure and is electrically connected to the control module of the treatment device body 1. It can preset the dosage according to the patient's condition and lesion size to achieve precise quantitative drug delivery, avoid waste caused by excessive drug delivery, and avoid affecting the treatment effect by insufficient drug delivery. In addition, the gel metering pump 21 has an anti-backflow function, which can prevent the injected gel from flowing back to the storage tank through the gel delivery tubing 22 to avoid contaminating the gel in the storage tank. It is a relatively mature gel injection component.

[0031] In the process of treating cervical lesions with this device, during the preoperative preparation stage, the anti-HPV gel is first injected into the medical-grade sealed anti-HPV gel storage tank 2, and the dosage of the gel quantitative injection pump 21 is preset through the control module of the treatment device body 1, while the heating temperature of the electric heating plate 44 is adjusted to match the body temperature. During the pretreatment stage of the injection connector, the operator manually pushes the first piston handle 34 to drive the glue injection sleeve 31 to slide along the protective sleeve 41 axially, so that the glue application elbow 321 is completely embedded in the elbow dustproof groove 412 of the protective sleeve 41. The sealing fit between the opening of the glue application elbow 321 and the inner wall of the protective sleeve 41, as well as the sealing effect of the water-blocking ring between the glue injection sleeve 31 and the protective sleeve 41, prevents contamination by body fluids during subsequent insertion. During the insertion and anti-dislodgement fixation stage of the injection connector, the operator slowly inserts the injection connector into the patient's vagina by holding the second piston handle 43 until the rubber plug 52 reaches the vaginal opening. At this time, the protective sleeve 41 is located at the cervical opening. Since the rubber plug 52 with decreasing diameter can be adapted to different sizes of vaginal openings, it can be inserted smoothly without damaging the internal mucosa. By rotating the second piston handle 43, the relative angle between the protective sleeve 41 and the locking disc 42 and the ratchet disc 51 and the rubber plug 52 is changed. The rough surface of the silicone sheet 521 fits tightly against the inner wall of the vaginal opening. The friction of the silicone sheet 521 is used to achieve initial fixation. At this time, the return spring 4212 in the guide lock frame 421 is in the natural state, pushing the wedge-shaped locking block 4211 to engage in the wedge-shaped locking groove 511 of the ratchet disc 51, realizing the one-way locking of the ratchet disc 51, preventing it from rotating in the opposite direction, further fixing the injection connector, and avoiding the connector from falling off or shifting due to the patient's tension, trembling, or changes in body position during the drug administration process. During the lesion localization and injection module adjustment phase, the optical imaging unit 331 is activated, and the images of the cervical lesion area it acquires are transmitted to the display terminal of the treatment device body 1 through the imaging hard line 33 and the image guide 11. Medical staff observe the lesion location through the images, accurately determine the drug delivery angle, hold the first piston handle 34, and slowly push the injection sleeve 31 along the sliding cooperation direction of the guide protrusion 311 and the guide groove 411, so that the glue-applying elbow 321 and the optical imaging unit 331 extend out of the protective sleeve 41 until the glue-applying elbow 321 fits the curved surface of the cervical lesion. The cooperation between the guide protrusion 311 and the guide groove 411 can prevent the injection sleeve 31 from rotating and shifting, ensuring that the glue-applying elbow 321 and the optical imaging unit 331 always maintain the preset angle, ensuring accurate positioning. During the precise drug delivery phase, after confirming that the adhesive-coating elbow 321 is aligned with the lesion, the gel metering pump 21 is activated. The pump delivers the anti-HPV gel precisely to the injection tube 32 through the infusion tubing 22, and then evenly distributes it to the cervical lesion area through the adhesive-coating elbow 321. At the same time, the heating pad 44 obtains electrical energy through the electrode interface 431 and the heating wire 12. The heating pad 44 generates heat evenly, which softens the anti-HPV gel, improves its fluidity, and ensures even distribution. On the other hand, it promotes local blood circulation in the cervix, enhances drug absorption, and relieves the discomfort caused by cervical sensitivity in patients. After the drug administration is completed, pull the first piston handle 34 to retract the adhesive-coated elbow 321 and the optical imaging unit 331 into the elbow dustproof groove 412 of the protective sleeve 41, thereby achieving a seal and protection to prevent the components from being contaminated or damaged during the removal process. Then, slowly pull out the injection connector until the rubber plug 52 is detached from the patient's vaginal opening, thus completing the gel injection.
