The invention discloses an
interventional therapy auxiliary mechanical arm which comprises a stand, a position regulating mechanism, a gesture regulating mechanism, a working end and a
control system, wherein the position regulating mechanism is arranged on the stand and used for regulating a three-dimensional space position of the working end; the gesture regulating mechanism is arranged at the
tail end of the position regulating mechanism, the working end is arranged on the gesture regulating mechanism, the gesture regulating mechanism is used for regulating a space angle of the working end; and the
control system is used for controlling the position regulating mechanism and the gesture regulating mechanism to work. According to the
interventional therapy auxiliary mechanical arm, the three-dimensional space position of the working end is regulated by adopting the position regulating mechanism, the gesture regulating mechanism is used for regulating the space angle of the working to ensure that the working end is regulated to a needle feeding path position so as to conveniently realize that a needle feeding path is indicated or the needle feeding operation is completed. The
interventional therapy auxiliary mechanical arm has the advantages of simple structure, lower cost and convenience for operation.
