Interventional therapy auxiliary mechanical arm

Abstract

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.

Description

【Technical field】 [0001] The invention relates to the field of medical equipment, in particular to an interventional treatment auxiliary mechanical arm. 【Background technique】 [0002] Intervention therapy is an emerging treatment method between surgery and medical treatment. It refers to the treatment of blood vessels without surgical exposure of the lesion. It is the least traumatic treatment method to treat the lesion locally under the guidance of imaging equipment through a tiny channel with a diameter of a few millimeters on the skin, or through the original pipeline of the human body. [0003] The traditional mechanical arm is mostly used for the fixation of the patient's body during the operation, and the surgical instrument clamping and other auxiliary functions, but in the process of interventional therapy, it cannot provide the puncture needle path, the patient's body surface puncture needle point and other important operations. information. However, the mechanic...

Problems solved by technology

[0003] The traditional mechanical arm is mostly used for the fixation of the patient's body during the operation, and the surgical instrument clamping and other auxiliary functions, but in the process of interventional therapy, it cannot provide the puncture needle path, the patient's body surface puncture needle point and other important operations. information

However, the mechanical arm that can provide the puncture needle path and puncture needle entry point has a complex structure, complex control algorithms, and is expensive.
