Description

Technical Field

[0001] The invention belongs to the technical field of medical puncture equipment, in particular to a pneumoconiosis pathology puncture positioning device. Background Art

[0002] Pneumoconiosis patients inhale industrial dust (dust) for a long time during their occupational activities, and the dust accumulates in the lungs, causing a systemic disease characterized by diffuse fibrosis (scarring) of the lung tissue. It can be divided into inorganic pneumoconiosis and organic pneumoconiosis. The more effective method for treating the lungs of pneumoconiosis patients at present is to use a positioning puncture needle under CT guidance, which is simple, effective and rapid. Although the positioning puncture needle in the existing technology can locate the patient's lungs, the positioning accuracy during the positioning process needs to be improved, and the needle is prone to fall off, resulting in the inability to accurately locate the lungs in later operations; in addition, the positioning puncture needle is difficult to pull out after the guide wire is expanded, and the barbed anchor needle is prone to scratching the adjacent lung tissue, blood vessels, etc. during retraction.

The upper locking member is driven by the linkage rod to swing accordingly mainly through the rotation of each threaded inner rod, thereby facilitating the adjustment of the puncture angle with higher accuracy.

[0062] As a preferred embodiment, an axle seat 31 is embedded and fixed in the fixed sleeve 3, a guide shaft 32 is rotatably set in the axle seat 31, the puncture needle 2 is sealingly and slidingly connected to the guide shaft 32, and an air pressure cover 34 is embedded and fixed in the fixed sleeve 3, the lower end face sealing ring of the air pressure cover 34 is connected to a negative pressure ring pad 35, an air flow pump 33 is installed on one side of the fixed sleeve 3, one end of the air flow pump 33 is connected to the negative pressure ring 35 through a transfer tube, and the air flow pump 33 is also connected to the air pressure cover 34 through an internal tube 36, especially in use, the negative pressure ring is preferentially in contact with the patient's skin under the action of negative pressure, and then the air pressure cover can realize the main body of the fixed sleeve adsorption fixation under negative pressure. In this regard, special attention should be paid to the negative pressure adsorption strength, which should be kept within the safe use range.

[0063] In this embodiment, the upper locking member 4 includes:

[0064] External pipe 41;

[0065] An inner locking sleeve 42 is coaxially disposed within the outer tube 41;

[0080] The pressure piece 66 is fixed on the inner shaft column 65. The pressure piece 66 can be in contact with the sliding ring 64. That is, when the inner shaft column slides along the positioning needle under the action of air pressure, the inner tube body slides and separates from the upper tube sleeve, and the sliding ring is gradually pushed by the pressure piece during the displacement of the inner tube body, so that the side hooks can be expanded and extended, and their installation angles can be controlled during the extension to actively grasp the lung tissue.

[0081] In this embodiment, an inner spring (not shown in the figure) is connected between the support rod 61 and the sliding ring 64 .

[0082] Specifically, when puncturing the lung tissue of a pneumoconiosis patient, the fixed sleeve is preferably brought into contact with the patient's skin and fixed by adsorption, and then the angle of the upper locking member is adjusted so that the puncture needle can puncture accurately. During the puncture process, the puncture angle can also be fine-tuned by the fine-tuning effect of each linkage rod to reduce the difficulty coefficient of the surgical operation. After puncturing to the specified depth, the upper locking member will position the main body of the puncture needle, and then the medical staff can perform related operations related to the positioning needle. After the positioning needle penetrates into the diseased part of the lung tissue, the adjacent lung tissue can be actively grasped by the adjusting barb group, and the adjusting barb group can safely retract and withdraw the hook after the operation to avoid scratching or puncturing the human lung tissue.
