Multi-angle motion treatment bed

Abstract

The invention relates to a treatment bed capable of realizing multi-direction motion, containing a base, an X direction movement bed body, a lifting bed body, a rotating bed body, a Y direction rotating bed body, an X direction rotating bed body and an upper bed board. The X direction rotating bed body is connected with the base and can move in the X direction relative to the base. The lifting bed body is connected with the X direction rotating bed body and can move in the Z direction relative to the X direction rotating bed body. The rotating bed body is connected with the lifting bed body and can rotate in XY plane relative to the lifting bed body. The Y direction rotating bed body is pivotally connected with the rotating bed body and can swing relative to the rotating bed body in Y direction. The X direction rotating bed body is pivotally connected with the Y direction rotating bed body and can swing in X direction relative to the Y direction rotating bed body. The upper bed board is connected with the X direction rotating bed body and can move in Y direction relative to the X direction rotating bed body. By adopting the treatment bed capable of realizing multi-direction motion, the positioning precision problem of the treatment bed can be resolved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a treatment couch capable of multi-angle movement in gamma knife equipment. Background technique [0002] Gamma Knife equipment must include a treatment bed that carries the patient. When the treatment bed is treating tumors in different parts of the patient, it needs to move up and down, left and right, and back and forth to adjust the irradiation position. Such as figure 1 As shown, the existing treatment bed includes a base 21 , a bed 22 , a middle bed 23 and a bed board 24 . The middle bed 23 , the bed 22 and the bed board 24 are connected to each other through two vertical linear guide rails 25 , and the bed 22 and the base 21 are connected through a vertical guide rail 26 . In this way, the treatment couch can only move in the X-axis direction, Y-axis direction, and Z-axis direction to compensate for the position error caused by the placement of the radioactive source i...

Problems solved by technology

However, in the actual use process, there will be a position error of six degrees of freedom, and the existing treatment bed cannot accurately position the patient, resulting in treatment error
