Abstract

The invention discloses an indexing head mechanism of a high-dose-rate multi-channel after-loading therapy apparatus. The indexing head mechanism comprises a shell; a vertical mounting plate is fixedly connected into the shell, an indexing disc which is parallel to the vertical mounting plate is arranged at the rear of the vertical mounting plate and is driven by a stepper motor, and the stepper motor is fixedly mounted on the vertical mounting plate; an S-shaped guide tube is fixedly connected onto the indexing disc, an outlet of the S-shaped guide tube extends out of the indexing disc and is opposite to an inlet of one of a plurality of connecting guide tubes, the multiple connecting guide tubes are fixed onto the vertical mounting plate, and outlets of the connecting guide tubes are connected with external therapy guide tube interfaces. The indexing head mechanism has the advantages of simple structure, convenience in manufacture and easiness in maintenance.

Description

technical field [0001] The invention relates to the field of medical equipment, belongs to the frontier subject intersecting machinery and medicine, and in particular relates to brachytherapy equipment. Background technique [0002] In the treatment of cancer, in addition to surgery and chemotherapy, radiation therapy is also an important means. Radiation therapy is a treatment method that irradiates tumors with rays of different energies to inhibit and kill cancer cells. According to the radiation method, it can be divided into long-distance irradiation and brachytherapy. Long-distance irradiation, that is, external irradiation, is to use X-ray therapy machines to focus the rays outside the human body for short-term irradiation on the body surface or tumor parts in the body to kill tumor cells. Brachytherapy is to permanently or temporarily introduce high-dose-rate radioactive source particles into the cancerous part of the tumor through external devices, so as to kill tum...
