Embodiment 1

[0055] Embodiment 1: as attached figure 1 As shown, above the bracket 27, place the lead stopper frock 29, place the frock cover 31 or replace the source frock 26 in the middle part above the lead stopper frock 29; wherein, the lead plug frock 29 middle part is developed toward the edge of one side, and the upper and lower end faces are straight-through The installation slot and the tooling drawer 30 are slidingly placed therein. There is a vertical channel in the Z-axis direction in the middle part of the source tooling 26. The upper section of the vertical channel is a shaft hole. The X-axis chute communicates orthogonally and vertically, and the lower section of the vertical channel communicates with the slide rail in the X-axis or Y-axis, wherein one end of the X-axis chute is open and the other end is closed, and a shielding body 32 is placed in the X-axis chute , and the lower lead plug 24 is placed in the slide rail, and the inner section of the X-axis chute is located ...

Abstract

The invention provides a safe changing system of a gamma knife radiation treatment equipment radioactive source. A source changing tool (26) is changed and arranged above an effective protected transporting source lead tank (10) with an eliminated source tank lead plug (22) and an upper lead taking plug tool (29). A cobalt source box (20) is lifted from the transporting source lead tank (10) intothe source changing tool (26) for combining with a shielding member (32). The source changing tool (26) which comprises the cobalt source box (20) is conveyed to a position which corresponds with gamma knife equipment (11). Auxiliary tools such as bracket, tool cover, lead taking plug tool and the main pull rod realize convenient maintenance and repeated use. Dimension and self weight of the source changing tool are reduced. A multi-combined quick protecting structure in which the source changing tool and the lead taking plug tool are combined is designed. The safe changing system of a gamma knife radiation treatment equipment radioactive source has advantages of reducing workload of field personnel, reducing cost, improving safety in mounting and changing of the radioactive source, effectively improving in-position precision of treatment control and a treatment bed, and improving quality control of a body gamma knife.

Description

technical field [0001] The invention relates to the structure improvement technology of A61N5 / 10 gamma ray therapy or particle irradiation therapy equipment in the IPC classification, especially the safe replacement system of the radioactive source of the Gamma Knife radiation therapy equipment. Background technique [0002] Gamma Knife (Gamma Knife) is the main treatment method of stereotactic radiosurgery (Stereotactic Radiosurgery), based on the principle of stereotactic geometry, the normal tissue or diseased tissue in the brain is selectively determined as the target, and cobalt-60 is used to generate Gamma ray is used for one-time high-dose focused irradiation to cause focal necrosis or functional changes to achieve the purpose of treating diseases. [0003] The source loading structure, principle and process of the existing Gamma Knife radiation therapy system include the following: [0004] A. Build a shielded hot room in the machine room, if attached figure 1 and ...
