Abstract

The invention discloses an all-angle puncture guide device. The all-angle puncture guide device comprises a bedside fixing seat, an adjusting rod, a sliding rail fixing rod, an arc-shape sliding rail, a puncture needle and a puncture needle fixing seat; the puncture needle is fixed on the puncture needle fixing seat, and the puncture needle fixing seat is arranged on the arc-shape sliding rail and is capable of sliding along the arc-shape sliding rail; the puncture needle points towards a sphere center of the arc-shape sliding rail all the time in a sliding process. The all-angle puncture guide device is simple in structure, convenient to operate, accurate in location, and is capable of realizing the all-angle puncture.

Description

technical field [0001] The invention belongs to the field of medical auxiliary devices, and relates to an auxiliary positioning and guiding device for puncturing human organ tissues, in particular to an all-angle puncturing and guiding device. Background technique [0002] Human organ tissue lesions (such as tumors) sometimes require biopsy or treatment of the lesion by puncture. The puncture of the lesion requires the positioning of the puncture site, usually with the help of medical imaging systems, such as ultrasound, C-arm X-ray machine, DSA, CT, and MRI. appears in: [0003] 1. Ultrasound: Although it can be positioned and guided in real time from multiple angles, it is easily affected by the tissue at the puncture site (such as bone, gas). In addition, the ultrasound only displays a plane image, and the puncture process does not show enough spatial relationship of the puncture needle in the human body. Participation of sonographers is required; 2. X-ray imaging syste...
