Pulmonary nodule puncture suite

Abstract

The invention relates to a pulmonary nodule puncture suite, and belongs to the technical field of medical instruments. Comprising a hard puncture needle, a trocar, a sheath core and a silica gel stabilizer, a sheath core is arranged in the hollow trocar in a penetrating mode, and a hard puncture needle is arranged in the hollow sheath core in a penetrating mode. The silica gel stabilizer is a flat medical silica gel body, the silica gel stabilizer is provided with a pasting face used for being pasted to the skin of a patient, and a first mark point is arranged on the pasting face. The pulmonary nodule puncture kit provided by the invention can be used for pathological sampling of lung cancer; the puncture suite punctures under the guidance of CT or DSA, accurate positioning and sampling are achieved, meanwhile, puncture injuries are reduced, and puncture safety is improved.

Description

technical field [0001] The invention relates to a pulmonary nodule puncture kit, which belongs to the technical field of medical instruments. Background technique [0002] Lung cancer is one of the malignant tumors that pose the greatest threat to human life and health. According to statistics from the National Cancer Center in 2019, there were 787,000 new cases of lung cancer in my country in 2015, showing a continuous growth trend. The morbidity and mortality of lung cancer rank first in my country and the world. Pathological diagnosis is the gold standard for the diagnosis of lung cancer and the prerequisite for comprehensive treatment of lung cancer. Lung biopsy is the main method for obtaining pathological diagnosis of lung tissue; it often includes multiple methods, such as CT-guided percutaneous lung biopsy, fiberoptic bronchoscopy, EBUS or magnetic navigation biopsy, and thoracoscopic biopsy. In clinical work, except for some central lung space-occupying lesions th...

Problems solved by technology

The current CT and DSA guidance can accurately locate the nodule position, set the puncture route, and provide laser navigation, which greatly improves the puncture accuracy; however, the puncture needle is required to be consistent with the navigation direction during the actual operation. The operator must maintain the direction of the puncture needle well in order to ensure the correct path and ensure the accuracy of the puncture; at the same time, the current biopsy technique usually uses the trocar first, the needle body is thicker, and the puncture resistance is high, which will also affect the operator. Direction control, while the adjustment of deviation from the lesion also increases the puncture damage

Therefore, in this technical field, there is an urgent need to solve the technical problems that the trocar is used as the first step in the current puncture biopsy, the needle body is relatively thick, and the puncture resistance is large, which affects the operator's direction control. At the same time, it is easy to increase the puncture damage during adjustment.
