Description

Technical Field

[0001] The present invention relates to the technical field of fixing devices, in particular to a thoracic lung puncture needle fixing device. Background Art

[0002] Lung puncture is a procedure in which a sterile needle is inserted through the skin, intercostal tissue, or parietal pleura to enter the lung. It is a common diagnostic and therapeutic method. A common method is CT-guided percutaneous lung puncture for biopsy or treatment of lung lesions.

[0003] In clinical practice, when performing lung puncture, the puncture needle must be sterile. Due to the obstruction of the body's bony structure, the needle cannot be inserted vertically in many cases, but at a certain angle. During the operation, the surgeon needs to leave the operating table many times and cannot continuously fix the puncture needle. The tail end of the puncture needle may shake, causing the puncture direction to change. Repeated CT scans are required to adjust the angle, which increases the patient's radiation exposure and puncture damage, and increases the difficulty of the doctor's operation. The puncture needle also needs to be manually fixed after insertion, but due to manual hand shaking, the puncture needle tip may scratch the patient's internal organs, increasing the risk of the operation.

[0004] Therefore, in response to the above problems, we propose a thoracic and pulmonary puncture needle fixing device to display the needle insertion angle during needle insertion, fix the puncture needle and keep the puncture needle stable during the puncture process. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In view of the shortcomings of the existing technology, the present invention designs a lung puncture needle fixing device on a chest cavity lung puncture needle fixing device. When in use, the tail of the puncture needle is placed inside the second ring, and the second knob is turned to drive the two groups of extrusion fixing blocks to approach each other through the third threaded rod to fix the puncture needle. Then, the second telescopic rod is slid along the two groups of first telescopic rods to penetrate the puncture needle into the patient's body, thereby reducing the situation where the needle tip may scratch the patient's internal organs due to manual trembling after the puncture needle penetrates the human body. It solves the problem that the surgeon needs to leave the operating table many times during the operation and cannot continuously fix the puncture needle. The tail end of the puncture needle may shake, causing the puncture direction to change, and repeated CT scans are required to adjust the angle, which increases the patient's radiation exposure and puncture damage, and increases the difficulty of the doctor's operation. The puncture needle also needs to be fixed manually after insertion, but due to manual trembling, the needle tip of the puncture needle may scratch the patient's internal organs, thereby increasing the risk of surgery.

[0020] 1. The present invention designs a lung puncture needle fixing device on a chest cavity lung puncture needle fixing device.
