Background

Photodynamic therapy (PDT) is a novel method for treating tumors, precancerous lesions, proliferative skin diseases and vascular diseases by using photosensitizing drugs and laser activation. The irradiation of the focus part with specific wavelength can activate the photosensitive medicine selectively gathered in the focus tissue to trigger photochemical reaction to destroy focus. The photosensitizing drugs in the new generation of photodynamic therapy (PDT) transfer energy to surrounding oxygen, generating singlet oxygen with very high activity. The singlet oxygen can perform oxidation reaction with the nearby biomacromolecule to generate cytotoxin so as to kill the lesion cells. PDT has the advantage over conventional therapies that it enables accurate and effective treatment with minimal side effects.

Currently photodynamic therapy is an emerging field of tumor treatment, and in gynaecological indications are: high risk HPV infection, cervical intraepithelial neoplasia, cervical cancer (unable to operate or recur after operation), vaginal cancer, vulvar cancer, etc. The advantages are that the method is minimally invasive and even noninvasive, can eliminate hidden focus, selectively kill tumor cells, does not destroy normal tissues, can keep the structural integrity of female genital organs, and does not affect normal fertility requirements. Because of no obvious systemic adverse reaction, the medicine is particularly suitable for patients with poor general conditions and no tolerance to other treatment methods, and can repeatedly treat for many times. The medicine is applied locally, and has little side effect on the whole body.

The shape of the abutting ring 13 is consistent with that of the cervical fornix of the human body, when the abutting ring 13 is placed in the cervical fornix of the human body, the abutting ring 13 can prop open folds of the cervical fornix, so that the abutting ring 13 is more attached to the cervical fornix, and the treatment effect is better.

Referring to fig. 2 and 3, in order to facilitate manipulation of the abutment ring 13 through the vagina to the cervical fornix, a control member 3 is provided on the abutment ring 13 to control the opening of the abutment ring 13 or the contraction of the abutment ring 13. When the abutting ring 13 is required to be placed in the cervical fornix, the abutting ring 13 can be controlled by the control piece 3 to be attached to the first probe rod 11, so that the abutting ring 13 can be conveniently penetrated through the vagina to reach the cervical fornix; when the abutting ring 13 reaches the cervical fornix, the abutting ring 13 can be controlled to be unfolded through the control piece 3, so that the abutting ring 13 restores the bowl-shaped structure to unfolded the folds at the cervical fornix, and cancer cells at the cervical fornix can be eliminated.

Referring to fig. 2 and 3, in one example of the present application, the abutment ring 13 has a memory property, and the abutment ring 13 is bowl-shaped in its own memory state. And be provided with turn-ups 31 at the butt ring 13 outer lane, turn-ups 31 are buckled to the direction that butt ring 13 inner wall is located, have placed stay cord 32 in turn-ups 31, and stay cord 32 middle part is located turn-ups 31, and the both ends of stay cord 32 wear out from turn-ups 31 to pass from the inside of butt ring 13 and the inside of second probe pole 12, finally stretch out the external world from the one end that second probe pole 12 kept away from first probe pole 11. Normally, the abutting ring 13 is bowl-shaped under the action of the self memory attribute of the abutting ring 13. When the abutting ring 13 is required to be placed in the cervical fornix, a doctor can pull the end part of the stay cord 32 extending out of the second probe rod 12, so that the stay cord 32 positioned in the flange 31 is driven to be reduced, the open end of the abutting ring 13 is contracted, and the abutting ring 13 can be very conveniently penetrated from the vagina at the moment. Until the abutment ring 13 is positioned at the cervical dome, at which point the force exerted on the pull cord 32 is released and the abutment ring 13 recovers under its own memory properties.

Referring to fig. 4, in another example of the present application, the abutment ring 13 is made of soft transparent material, such as transparent silica gel. The abutting ring 13 is of a hollow structure with a hollow inside, and the inside of the abutting ring 13 is not communicated with the inside of the second probe rod 12. The control member 3 comprises an air charging pipe 33 and an air discharging pipe 34 which are positioned in the second probe rod 12, wherein the uniform ends of the air charging pipe 33 and the air discharging pipe 34 are communicated to the inside of the abutting ring 13, and the other end of the air charging pipe extends to the outside from one end of the second probe rod 12 far away from the first probe rod 11. It will be appreciated that valves for controlling the on-off of the air inflation tube 33 and the air deflation tube 34 are installed at the ends of the air inflation tube 33 and the air deflation tube 34 located outside, and the ends of the air inflation tube 33 located outside are connected with external inert gas (such as nitrogen). When it is necessary to place the abutment ring 13 in the cervical fornix, the gas in the abutment ring 13 can be discharged through the gas discharge pipe 34, and at this time, the abutment ring 13 loses support and contracts, so that the vagina can pass smoothly to reach the cervical fornix. When the abutting ring 13 reaches the cervical fornix, the external inert gas is conveyed into the abutting ring 13 through the gas filled tube 33, so that the abutting ring 13 can be spread, and the abutting ring 13 is attached to the cervical fornix.
