Problems solved by technology
[0003] The existing above-mentioned products are additional radiation protection devices designed only for X-ray machines. Due to the strong penetrating power of gamma rays, the shielding effect of the above-mentioned products on gamma rays emitted by the gamma knife is very weak, and it is not effective at all. For the purpose of radiation protection, combined with domestic published literature, there is no report on the application of Gamma Knife γ-ray radiation protection device

Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0031] The present invention innovatively designs a new type of radiation shielding instrument---dual-controlled automatic Gamma Knife radiation shielding instrument, which is mainly used in Gamma Knife radiosurgery equipment and is an additional radiation protection measure , to prevent radiation leakage due to the limited shielding effect of the Gamma Knife equipment itself, there is still a small part of rays passing through the slit of the Gamma Knife shiel...

The invention discloses a dual-controlled automatic gamma knife ray shielding device. A ray shielding device is installed in front of a gamma knife radiation source emergent ray shielding door and canmove left and right along a gamma knife head. Two ends of a toothed guide rail are arranged on columns at two sides. A gear connection is formed by the toothed guide rail and a bearing pulley. The bearing pulley is connected to a motor, and the toothed guide rail runs under the drag of the motor. A cover plate is arranged above the toothed guide rail and covers the toothed guide rail and a hangerslideway. The hanger slideway is arranged under the toothed guide rail. A ray protection screen hanger and a combined hanger are slidingly arranged on the hanger slideway. The ray protection screen hanger is connected to the combined hanger, the combined hanger is connected to the toothed guide rail through a connection guide rail, and a ray protection screen is suspended under the ray protectionscreen hanger. The motor is electrically connected to an automatic controller. The switch button is electrically connected to the automatic controller. An emergency brake button is electrically connected to the motor.
Description
technical field [0001] The invention relates to the field of ray shielding instruments, in particular to a dual-control automatic gamma knife ray shielding instrument. Background technique [0002] In the prior art, in the Chinese literature about the ray radiation protection device, the radiation protection device attached to the X-ray machine of the interventional equipment is mostly reported, and the devices often included are as follows: traditional lead protective articles, such as lead apron, lead neck, lead cap , lead glasses; simple lead protective devices, such as bedside lead curtains, bed protective screens, bed curtains and lead screens, etc.; protective devices equipped with mechanical and electric devices, such as mobile X-ray protective screens. [0003] The existing above-mentioned products are additional radiation protection devices designed only for X-ray machines. Due to the strong penetrating power of gamma rays, the shielding effect of the above-mentione...
