B-mode ultrasound monitoring moving mechanism for high intensity focused ultrasound (HIFU) treatment

Abstract

The invention provides a B-mode ultrasound monitoring mechanism for high intensity focused ultrasound (HIFU) treatment. The B-mode ultrasound monitoring mechanism for HIFU treatment comprises a lifting motor module, a lifting mechanism guide module, a lifting cylinder and a B-mode ultrasound probe fixing module, wherein the lifting motor module comprises a lifting motor and a screw rod nut mechanism; the lifting mechanism guide module is connected with the screw rod nut mechanism; the lifting cylinder is matched with the lifting mechanism guide module to form a precision guide motion pair; andthe B-mode ultrasound probe fixing module is connected with the lifting mechanism guide module through pressure transmitters, and a B-mode ultrasound probe is arranged on the B-mode ultrasound probefixing module. According to the B-mode ultrasound monitoring mechanism for HIFU treatment, the pressure transmitters are arranged on the lifting mechanism guide module and the B-mode ultrasound probefixing module, a measurement signal is generated through pressure difference applied to both sides, so that the pressure transmitters only measure the pressure applied to a patient without measuring system friction force, the B-mode ultrasound probe can be driven to move precisely according to the treatment requirements, the focal area can be accurately located and monitored, and the accuracy of area setting and the quality of process monitoring are improved.

Description

technical field [0001] The invention belongs to the field of ultrasound guidance for upper-mounted high-intensity focused ultrasound (HIFU) treatment, and relates to a B-ultrasound monitoring movement mechanism. Background technique [0002] High-intensity focused ultrasound therapy (HIFU therapy) is a non-invasive treatment method developed in recent years, especially in the field of tumor ablation with good results. This technology focuses low-energy ultrasound in vitro on the target area in the body, and produces biological effects such as instantaneous high temperature, cavitation and mechanical action in the tumor to kill tumor cells in the target area. [0003] At present, the HIFU treatment system guided by B-ultrasound images is widely used at home and abroad. The system uses B-ultrasound images to locate and monitor lesions for precise treatment. The shorter the distance from the B ultrasound to the lesion, the better the image quality and the more accurate the po...
