Radiotherapy protective device in gynecological tumor cavity

Abstract

The invention discloses a radiotherapy protective device in the gynecological tumor cavity. The device comprises a guard plate assembly, a fixed tray and a connecting sleeve, wherein one end of the guard plate assembly is fixedly connected with the fixed tray, the fixed tray is provided with a fixed clamping groove, the middle of the fixed tray is provided with a source applicator fixing frame, the other end of the guard plate assembly is provided with a connecting table, the connecting table is fixedly connected with the connecting sleeve, the connecting sleeve is provided with a telescopic joint, the telescopic joint is in embedded connection with a connecting rod, the connecting rod is connected with a cardan joint connection, and the cardan joint connection is connected with an elongated telescopic rod. The radiotherapy protective device in the gynecological tumor cavity has the advantages that a unique combined conical structure is adopted to adapt to a body structure, a adjustingstructure of the number of required trapezoidal guard plates is selected and adopted according to the size and shape of tumors and the distribution positions of the tumors in vivo, the radiotherapy protective device can also elongate freely, transform any angle and perform tracking and protection in the process of treatment, thereby reducing radiotherapeutic reaction and improving the therapeuticeffect.

Description

technical field [0001] The invention relates to the technical field of intracavitary radiotherapy for gynecological tumors, in particular to a protective device for intracavity radiotherapy of gynecological tumors. Background technique [0002] At present, in the treatment of gynecological tumors, intracavitary radiation therapy is often used. Because most of the intracavitary tumors grow infiltratingly and their general shape is irregular, radiation therapy will also cause one-time or permanent damage to normal tissues and organs, even at the cost of sacrificing some important organs. At present, there are some protective equipment made of lead plates or stainless steel encapsulating lead plates in clinical work, but lead is poisonous, and it is not safe as a protective material for clinical use. In addition, these protective devices cannot effectively track and protect tumors of different shapes and sizes in different positions in the body, so that the tumors cannot be co...

AI Technical Summary

Problems solved by technology

At present, there are also some protective equipment made of lead plates or stainless steel encased lead plates in clinical work, but lead is poisonous, and it is not safe to use as protective materials for clinical use.

In addition, these protective devices cannot effectively track and protect tumors of different shapes and sizes in different positions in the body, so that the tumors cannot be completely lethally irradiated, and the normal tissues next to the tumors cannot be effectively protected. Hurt
