Beam-defining clipper and X-ray machine

Abstract

The invention relates to a beam-defining clipper. The beam-defining clipper comprises a box body, a filtering assembly, an adjusting assembly and a transmission rope, wherein the box body comprises amain body and a basal plate; the main body is provided with an accommodating cavity and an opening which communicates with the accommodating cavity; the basal plate is connected to the opening of themain body; the filtering assembly is in pivot rotating connection to one side facing the accommodating cavity, of the basal plate around a first axis; the adjusting assembly is in pivot rotating connection to the basal plate around a second axis, wherein an angle is formed between the second axis and the first axis; one end of the adjusting assembly extends out of the main body; and the transmission rope is arranged between the filtering assembly and a part located in the accommodating cavity, of the adjusting assembly in a winding manner, so that the rotating of the adjusting assembly and therotating of the filtering assembly are mutually linked. According to the beam-defining clipper disclosed by the invention, only one hole allowing one end of the adjusting assembly to extend is needed, so that the size of the formed hole is effectively reduced, internal radiation leakage is effectively reduced, and the health of an operator is guaranteed. The invention also relates to an X-ray machine.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a beam limiter and an X-ray machine. Background technique [0002] In an X-ray machine, the beam limiter is usually installed under the tube, which emits X-rays, which are projected onto the subject through the blade openings inside the beam limiter. A filter is usually arranged inside the beam limiter, and the filter plays the role of filtering soft rays. The optical filter in the existing beam limiter is switched by a paddle or a lever structure. However, this switching method requires a larger opening on the beam limiter for the movement of the paddle or lever structure. The larger opening will cause more internal radiation leakage and affect the health of the operator. Contents of the invention [0003] Based on this, it is necessary to provide a beam limiter and X-ray that can effectively reduce the radiation leakage in the beam limiter and ensure the health ...
