Problems solved by technology

Therefore, during the whole process of photodynamic therapy, the medical staff need to hold the light-guiding optical fiber to position the affected area for tens of minutes, which is inconvenient for both the doctor and the patient, and the repeated use of the optical fiber directly into the patient's vagina is likely to cause cross-infection of the patient, which greatly affects the curative effect
In addition, during treatment, the optical fiber guides a certain intensity of laser light from the laser, and its light-emitting end face may generate high heat and other phenomena under unexpected circumstances, which will cause damage to the patient; again, patients with condyloma acuminata and cervical lesions are often accompanied by viruses (such as human nipple Tumor virus, etc.) infection, repeated use of optical fiber can easily lead to cross-infection of viruses between patients

Embodiment 1

[0015] Such as figure 1 As shown, a fiber optic sleeve for the vagina and cervix includes: a sleeve body 1 with an optical fiber through hole inside, and its front part is a circular frustum-like structure 4 with an arc-shaped outer side, and the diameter of the front end of the circular flange 4 is just suitable for insertion Vagina; the diameter of the remaining part of the casing main body 1 connected with the round platform 4 is smaller than the diameter of the front end of the round platform 4 . A hollow arc-shaped protrusion 2 is provided at the head end of the sleeve main body; the arc-shaped protrusion 2 is connected to the sleeve main body 1 by a coaxial tubular connecting member 3; the coaxial tubular connection The part is 10mm long, and its diameter and the diameter of the arc-shaped protrusion at the head end are just suitable for insertion into the cervical canal. On the inner surface of the casing main body close to the bottom of the circular platform, a small ...

Embodiment 2

[0017] Such as figure 2 As shown, a kind of optical fiber sleeve for vagina and cervix includes: a cylindrical sleeve body 1 with an optical fiber through hole inside, and an inner hollow arc-shaped protrusion 2 is provided at the head end of the sleeve body; The arc-shaped protrusion 2 described above is connected to the casing main body 1 by a coaxial tubular connecting member 3, and the connecting surface is arc-shaped; the coaxial tubular connecting part is 10mm long, and its diameter is just suitable for Insert the cervical canal. When in use, the head end of the cannula is directly inserted into the cervical canal, and the optical fiber enters the cannula to perform phototherapy on the vagina and epicervix; when the treatment site is the cervical canal, the optical fiber can also directly enter the arc-shaped protrusion at the end of the cannula.

Embodiment 3

[0019] Such as image 3 As shown, a test tube-shaped optical fiber sleeve for the vagina and cervix includes a cylindrical sleeve body 1 with an optical fiber through hole inside, and an arc-shaped protrusion 2 at the head end of the sleeve body. The cannula has just the right diameter to fit into the vagina.

Abstract

The invention relates to an optical-fiber sleeve tube for vaginas and cervixes, which is used for treating women reproductive tract infections by matching with a photodynamic therapy. The optical-fiber sleeve tube for vaginas and cervixes is characterized by comprising a sleeve tube main body (1) in which an optical-fiber through hole is arranged, wherein the head end of the sleeve tube main body (1) is provided with a circular arc-shaped bulge (2) with a hollow inner part, and the circular arc-shaped bulge (2) and the sleeve tube main body (1) are connected by a coaxial tubular connecting member (3). The optical-fiber sleeve tube for vaginas and cervixes has the advantage of simple structure, can avoid optical fibers direct contacting patients to prevent the patients from being damaged by an overheated light-emitting position under the unforeseen circumstances and prevent the generation of cross infections. The circular arc-shaped bulge on the front end of the sleeve tube has the function of effectively protecting the vaginas or cervix walls of the patients from being scratched, and meanwhile, the optical-fiber sleeve tube is convenient for medical workers to fix the optical fibers in the specific position when carrying out the photodynamic therapy to ensure that treating light can cover diseased positions.

Description

technical field [0001] The invention relates to an optical fiber sleeve tube for vagina and cervix used in combination with photodynamic therapy for treating gynecological diseases. Background technique [0002] At present, photodynamic therapy is often used to treat gynecological diseases such as condyloma acuminata and cervical lesions in women. These diseases do not occur on the skin surface, but inside the vagina and cervix. Laser irradiation needs to enter the cavity. Therefore, during the whole process of photodynamic therapy, the medical staff need to hold the light-guiding optical fiber to position the affected area for tens of minutes, which is inconvenient for both the doctor and the patient, and the repeated use of the optical fiber directly into the patient's vagina is likely to cause cross-infection of the patient, which greatly affects the curative effect. In addition, during treatment, the optical fiber guides a certain intensity of laser light from the laser,...
