Intracavity probe ultrasonic intervention visual guiding device

Abstract

The invention relates to the technical field of medical machinery, and particularly relates to an intracavity probe ultrasonic intervention visual guiding device. The device comprises an ultrasonic probe and a guiding device, wherein a fixing frame is fixedly arranged on one side of the ultrasonic probe; the guiding device and a puncture needle are arranged on the fixing frame; the guiding device comprises a mounting base, a limiting plate, a nut base, a ball head and a supporting rod; the mounting base is driven by a driving device and performs horizontal linear motion on the fixing frame; the ball head is rotatably mounted in the mounting base; a pressing mechanism which has a locking effect on the ball head is arranged in the mounting base; one end of the supporting rod is fixedly connected with the ball head, and the other end of the supporting rod is fixedly connected with a clamping base; the limiting plate sleeves the front half part of the ball head and is detachably connected with the mounting base; and the puncture needle penetrates through the clamping base. The puncture needle can be automatically adjusted to a proper needle inserting angle, the needle inserting direction is quickly determined, and the whole operation is accurately and quickly conducted.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to a visualization guidance device for ultrasonic intervention of an intracavity probe. Background technique [0002] Ultrasonic intervention with intracavitary probe is an important means in interventional diagnosis and treatment of tumors. Ultrasound has the advantage of real-time guidance, and interventional biopsy and treatment have been widely used clinically; it is a method of percutaneous puncture or incision of a few millimeters under the guidance of ultrasound, and the introduction of special surgical instruments to wash and suction the lesion , medication and other diagnosis and treatment to make surgical treatment more accurate, it has the advantages of less trauma, high efficiency, safety, fewer complications, quick recovery, and no damage to the original anatomical structure. According to the angle and depth of the puncture needle, the puncture is performed w...
