Abstract

The invention relates to a needle inserting and implanting guiding device for internal radiotherapy. The central hole channel is formed along the central axis of the rod-shaped main body; the axial needle penetrating channels are uniformly distributed in the circumferential direction of the rod-shaped main body and are parallel to the central hole channel; the inclined needle inlets are formed in the side part of the tail end of the rod-shaped main body; the inclined needle outlets are formed in the side part of the head end of the rod-shaped main body; the inclined needle inlets and the inclined needle outlets are in one-to-one correspondence and are communicated through inclined needle penetrating channels. The device is convenient for positioning the implanting needle and is simple in structure.

Description

technical field [0001] The invention belongs to the technical field of radiotherapy auxiliary equipment, and in particular relates to a needle guide for internal radiotherapy. Background technique [0002] Cervical cancer is the most common gynecological malignancy, and its incidence tends to be younger in recent years. The widespread application of cervical cytology screening in recent decades has enabled early detection and treatment of cervical cancer and precancerous lesions, and the incidence and mortality of cervical cancer have dropped significantly. [0003] Cervical cancer treatment mainly includes surgery, radiation therapy and chemotherapy. With the rapid development of precise radiotherapy with precise positioning and precise treatment as the core, targeted radiotherapy has become a research hotspot. Implantation therapy is to insert a hollow implantation steel needle into the tumor and connect it to a post-installation treatment machine. The radioactive source...
