Embodiment Construction

[0055] The meaning of the term "CT" used in the present invention is CT (Computed Tomography), that is, electronic computer tomography, which refers to the use of precisely collimated X-ray beams, γ-rays, ultrasonic waves, etc., together with highly sensitive detectors to surround An image inspection technique that scans sections of a certain part of the human body one by one. According to the different rays used, it can be divided into: X-ray CT (X-CT) and gamma-ray CT (γ-CT).

[0056] The terms "proximal end" and "distal end" used in the present invention refer to the positional relationship relative to the CT machine, that is, the end close to the CT machine is the proximal end, and the end far away from the CT machine is the far end.

[0057] as attached figure 1 As shown, a CT real-time positioning precise puncture system according to the present invention includes: a CT scanning device 10 , a puncture robot 20 , a control system 30 , an equal volume aspirator 40 , and a...

Abstract

The invention provides an equivalent aspirator. The equivalent aspirator comprises an oxygen source, a throttle valve, a valve set, a flexible air bag, a rigid container, an inflator pump, a mask assembly and a system controller. The flexible air bag is installed in the rigid container, high-pressure oxygen output by the oxygen source can inflate the flexible air bag at a fixed speed through the throttling valve and an electromagnetic valve, and the system controller accurately inflates a certain amount of oxygen into the flexible air bag by controlling the inflation time; the inflator pump enables air pressure in the rigid container to be higher than one atmospheric pressure; and the mask assembly comprises a mask body and a mask synchronous switch. Every time before CT scanning, a patient can inhale the same amount of air by using the equivalent aspirator, so that respiratory errors are reduced or eliminated, and the equivalent aspirator has important significance in interventional therapy or needle biopsy by using CT guidance.

Description

technical field [0001] The invention relates to an auxiliary device used in the medical image acquisition process, belonging to the technical field of medical image systems. Background technique [0002] CT intervention is a mature and effective percutaneous non-vascular interventional technique, including CT-guided percutaneous biopsy and interventional therapy, which can be used in various parts of the body, including the brain, chest, abdomen, and musculoskeletal systems. [0003] CT has high density resolution and spatial resolution, and can clearly show the size, shape, location and adjacency relationship between the lesion and surrounding tissues and organs. Accurately locate the lesion, and can clearly understand the internal and surrounding soft tissue of the lesion, so as to avoid important tissue structures or necrotic areas of the lesion, and can accurately determine the needle insertion point, angle and depth, and can be adjusted at any time under scanning monito...
