Example Embodiment

[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0017] like Figure 1-Figure 3 As shown, the present invention provides a lead mold device for a medical linear accelerator, which includes an enclosure frame 100 , a bottom plate 200 and a combined lead mold 300 . The bottom plate 200 is detachably connected under the enclosure frame 100 , and the inner cavity of the enclosure frame 100 is filled by the combined lead mold 300 . The combined lead mold 300 includes a plurality of slot lead bars 310 and protruding lead bars 320 in a rectangular parallelepiped structure. The four side walls of the slot lead bars 310 are provided with vertically distributed slots 311, each A lead insert 400 cooperating with the slot 311 can be installed in the slot 311 . The outer wall of the protruding lead bar 3...

Abstract

The lead mold device for a medical linear accelerator. The lead mold device for the medical linear accelerator comprises an enclosure frame, a bottom plate and a combined lead mold, wherein the bottom plate is detachably connected to the lower part of the enclosure frame, an inner cavity of the enclosure frame is filled with the combined lead mold, the combined lead mold comprises a plurality of inserting groove lead strips and outwards-protruding lead strips, and the inserting groove lead strips and the outwards-protruding lead strips are of cuboid structures; vertically-distributed inserting grooves are formed in the four side walls of the inserting groove lead strips correspondingly, lead inserting strips matched with the inserting grooves can be installed in the inserting grooves, outwards-protruding lead blocks matched with the inserting grooves are fixedly arranged on the outer side walls of the outwards-protruding lead strips, and the multiple outwards-protruding lead strips and the multiple inserting groove lead strips are arranged in a staggered mode to form a lead mold body; the lead mold body is assembled in the enclosure frame, the top of each outwards-protruding lead strip and the top of each inserting groove lead strip are fixedly connected with a handle, and the shape of the cavity on the lead mold body is adjusted to be matched with the shape of a tumor by extracting the inserting groove lead strips and the outwards-protruding lead strips according to the shape of a tumor, so that the lead mold device for the medical linear accelerator can be used by different patients while tumor radiotherapy is carried out, and resources and cost are saved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a lead mold device for a medical linear accelerator. Background technique [0002] In the clinical application of electron beam radiotherapy, due to the irregular shape of the tumor, if the standard irradiation field is used, the normal tissue will be irradiated, which will harm the body. In order to protect the normal tissue of the patient, an external lead mold is often used to change the shape of the standard irradiation field of the light-limiting tube, so as to adapt to the irradiation of the target area and protect the surrounding normal tissue. The lead molds currently used are lead plates with cavities of various shapes. By comparing the cavities of different shapes with the shape of the patient's tumor, the lead mold with a similar shape is selected to cooperate with the linear accelerator for radiation therapy. Since the shape of the cavity on the lead mold is ...
