Lung abscess puncture device with CT image guiding

Abstract

The invention discloses a lung abscess puncture device with CT image guiding. The lung abscess puncture device mainly comprises a clamping device, a movable hinged support, a movable arm, a puncture device body and a power device; the clamping device is connected with the movable arm through the movable hinged support, the puncture device is arranged on the movable arm, and the power device is arranged on the clamping device. The lung abscess puncture device is simple in structure, and has the advantages of being accurate in positioning and higher in safety; the lung abscess puncture can reduce the work load of a medical worker greatly because the size is small, movability is higher, and no geographical limitation exists, and adapts to popularization.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a CT image-guided lung abscess puncture device. Background technique [0002] Puncture is a term used in medical operations. It is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting drugs into the body cavity. The purpose of the puncture is to draw blood for testing, blood transfusion, infusion and catheterization for angiography. [0003] Lung abscess is a purulent lesion of lung tissue caused by various etiologies. In the early stage, it was purulent inflammation, followed by necrosis to form abscess. Occurs more in the prime of life, more men than women. According to the cause of the disease, there are infections caused by tracheal infection, blood-borne infection, multiple abscesses and lung can...

Problems solved by technology

[0005] In the prior art, one is to touch the approximate area of ​​the lung abscess according to the chest CT to determine the location of the lung abscess, and such a method will eventually have a large deviation; the other is to use CT guidance before the operation to use The hook-wire positioning needle is used for lung puncture through the chest wall; through repeated adjustments and groping, the needle is gradually approached to the location of the lung mass, and the "hook-shaped" metal hook-wire filament is released to make it stay near the tumor to locate the location of the lung mass During the operation, as long as the position of the hook-wire is found, the location of the tumor can be assisted to determine the extent of lung tissue to be resected; however, this method takes a long time for positioning, and the workload of medical staff and medical expenses are high.
