Abstract

The invention provides a precisely-guided cervical cancer source applicator. The precisely-guided cervical cancer source applicator comprises a base, an arc-shaped connecting plate and an end; the side portion of the base is connected with the side portion of the end head through an arc-shaped connecting plate, the end head is hemispherical, a plurality of needle holes I penetrating through the upper bottom face and the lower bottom face of the base are formed in the base, a plurality of needle holes II penetrating through the bottom face and the spherical face of the end head are formed in the end head, and the needle holes I correspond to the needle holes II in a one-to-one mode to form a plurality of needle channels. The device is scientific and reasonable in structure, can adapt to various patient conditions, achieves a precise treatment function, and has a good practical value.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a precisely guided applicator for cervical cancer. Background technique [0002] Existing applicators for radiotherapy for cervical cancer are generally cylinders, or cylinders with an oval cross-section, with a hemispherical groove at the head and a hemispherical protrusion at the tail; the source hole is generally located at the source In the middle of the device, or a plurality of source pipe holes are distributed centrally symmetrically, or a plurality of source holes are arranged irregularly, and the needle paths of each water source hole are parallel to the axis of the cylinder. For hysterectomy patients, the arrangement of the applicator holes in such an applicator structure cannot achieve the function of precise treatment. Moreover, the simple cylindrical body of the applicator in the prior art lacks a fixing function, and it is easy to rotate or slip out during the treatm...
