Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] See figure 1 , The cervical multi-point injection device includes an injection disc 1 , an inner core 2 of the injection disc and a microinjection needle 3 .

[0020] The injection disc 1 is a hollow disc made of medical non-toxic hard plastic, and is integrally formed by a first cylinder 101 and a second cylinder 102 . The first cylinder has a diameter of 12 mm and a length of 10 mm; the second cylinder has a diameter of 10 mm and a length of 100 mm. A sheet-like structure 4 is fixed on the outer periphery of the second cylinder 102 away from the first cylinder 101 .

[0021] The microinjection needle 3 is a hollow metal microinjection needle, which is fixed on the side of the first cylinder 101 away from the second cylinder 102, and communicates with the first cylinder 101, the number is 8, on the first cylinder 101 Arranged at equal interv...

Abstract

The invention discloses a multi-point microinjection device for a uterine neck. The multi-point microinjection device comprises a hollow injection disc, an inner core of the injection disc and multiple hollow microinjection needles. The injection disc is composed of a first cylinder and a second cylinder as a whole. The microinjection needles are secured on one surface, away from the second cylinder, on the first cylinder. One end of the inner core of the injection disc is fixedly connected with a piston head. The piston head is located into the first cylinder and closely combined with the cylindrical wall of the first cylinder and performs up-down motion in the first cylinder. The multi-point microinjection device for the uterine neck is capable of accurately injecting medicine for treating uterine neck lesions to the stratum basale of a cervical leather and keeping medicine in high concentration partially so that uterine neck lesions induced by an HPV virus are favorably treated; a patient may recover from uterine neck lesions; and the new medication therapy for treating uterine neck lesions can be applied; and the multi-point microinjection device is simple, viable, cost-effective and practical and is convenient for clinic use.

Description

technical field [0001] The invention relates to a cervical multi-point micro-injection device, in particular to an injection device for injecting medicinal liquid into cervical epithelial basal layer cells. Background technique [0002] With the widespread development of cervical cancer screening, a large number of cervical intraepithelial neoplasia has been found. Cervical intraepithelial neoplasia caused by human papillomavirus (HumanPapillomaVirus, HPV) infection can be divided into high-grade intraepithelial neoplasia and low-grade intraepithelial neoplasia, and high-grade intraepithelial neoplasia is precancerous lesions. Reasonable intervention for cervical intraepithelial neoplasia, especially low-grade lesions, is a hot research topic. Cervical intraepithelial neoplasia caused by HPV virus is limited to the cervical epithelium, and if the lesion continues to develop and break through the basal layer, it is cervical cancer. If it is not treated in time, it may endang...
