Abstract

The invention relates to a five-degree-of-freedom treatment focus positioning device for magnetic resonance guidance. The five-degree-of-freedom treatment focus positioning device comprises a drivingbed body, a working bed body and an auxiliary bed body, a probe connecting disc and a probe motion control assembly are arranged in the working bed body, and a motor speed changing set used for driving the probe motion control assembly is arranged in the driving bed body. The probe motion control assembly comprises a probe front-back moving mechanism, a probe left-right moving mechanism, a probe up-down moving mechanism, a probe rotating mechanism and a probe swing mechanism, an ultrasonic probe is installed on the probe connecting disc, and the treatment focus position is determined by the ultrasonic probe. The modular design of the driving bed body, the working bed body and the auxiliary bed body is adopted, the motor speed change set and the ultrasonic probe are completely separated, and the electromagnetic interference influence caused by the close distance between the motor set and the ultrasonic probe is avoided; due to the five-degree-of-freedom parallel structure design, the movement process is accurately controlled, the degrees of freedom do not interfere with one another, and the focus of the probe can be positioned more flexibly and conveniently.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a five-degree-of-freedom therapeutic focus positioning device for magnetic resonance guidance. Background technique [0002] Magnetic resonance-guided high-intensity focused ultrasound is a non-invasive thermal ablation technique based on real-time magnetic resonance imaging. In recent years, it has shown good results in the clinical treatment of uterine fibroids, brain tumors and other tumors. In recent years, With the continuous development of real-time imaging technology, this physical therapy technology can be monitored in real time during the treatment process, which greatly improves the accuracy of treatment, and has attracted more and more attention from the medical community. [0003] When the phase-controlled high-intensity focused ultrasound treatment system works under the guidance of imaging equipment such as magnetic resonance, it needs to obtain ...
