Embodiment 1

[0034] Embodiment 1: a kind of cell hairbrush that is used for pleural brush examination, such as figure 1 As shown, it includes a sleeve 1 and a needle core 2 inserted into the sleeve 1 . When the sleeve 1 is inserted into the pleural cavity, the needle core 2 is inserted into the sleeve 1 . It also includes a sealing tube 4 and a cell brush body 5 plugged into the sealing tube 4 , and the sealing tube 4 is sealed and connected with the sleeve 1 . One end of the cell brush body 5 is provided with a cell brush head 3 and the other end is provided with a cell brush handle 9 . The end of the sealing tube 4 close to the cell brush handle 9 is fixedly connected with a clamping body 7 , and the cell brush body 5 is inserted into the clamping body 7 . The sealing tube 4 is sealed and connected with the sleeve 1 to prevent external air from entering the pleural cavity, and reduce the occurrence of artificial pneumothorax during the pleural brushing process. Utilizing the cell brus...

Embodiment 2

[0040] Embodiment 2: a kind of method for using the cell hairbrush that is used for pleural brush examination, such as figure 1 and figure 2 shown, including the following steps:

[0041] Step 1, after the sleeve 1 enters the pleural cavity, the needle core 2 is taken out from the sleeve 1 .

[0042] Step 2, insert the sealing tube 4 into the sleeve 1 to seal the sealing tube 4 and the sleeve 1 .

[0043] Step 3: hold the cell brush handle 9 and the clamping body 7, shorten the distance between the cell brush handle 9 and the clamping body 7, and the cell brush body 5 sends the cell brush head 3 from the sealed tube 4 into the pleural cavity.

[0044] Step 4, rotate the sleeve 1, and perform the pleura brushing after the cell brush head 3 is in contact with the pleura. During the process of rotating the sleeve 1, the fan-shaped surface brushing of the pleura is realized by adjusting the length of the cell hair brush in the pleural cavity.

[0045] Step 5: After the pleura...

Abstract

The invention discloses a cell brush used for pleural brushing inspection and a using method thereof, relates to the technical field of medical instruments, and solves the problem that no special cellbrush used for pleural brushing inspection exists in the prior art, bronchoscope cell brushes are adopted in some literature reports, the cell brushes are too long and do not match with the exists pleural biopsy syringe, the cell brushes are difficult to sent out and take back, and artificial pneumothorax easily appears. The key points of the technical scheme are that: the cell brush comprises asleeve and a needle core inserted into the sleeve and further comprises a sealing tube and a cell brush body movably connected to the sealing tube, the sealing tube is sealingly connected to the sleeve; one end of the cell brush body is provided with a cell brush head, and the other end is provided with a cell brush handle; and the end of the sealing tube is fixedly connected to a clamping body near the cell brush handle, and the cell brush body is movably connected to the clamping body. The structure has the effects of making the cell brush simple to sent out and take back, facilitating pleural brushing inspection, increasing the number of tumor cells in the pleural effusion and improving the diagnostic positive rate of the malignant effusion.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a cell brush for pleural brushing and a method for using it. Background technique [0002] Pleural effusion cytology examination is widely used in the diagnosis of malignant pleural effusion; the number of tumor exfoliated cells in pleural effusion is the key factor restricting the positive rate of malignant pleural effusion diagnosis. [0003] At present, there is no cell brush dedicated to pleural brushing in the field of medical devices. The pleural brushing reported in a few literatures generally uses a disposable fiberoptic bronchoscope cell brush, which is passed through the core of a pleural biopsy needle into the pleural cavity for pleural brushing. [0004] Existing pleural brushing has the following defects: [0005] 1. The cell brush of the disposable fiberoptic bronchoscope is too long, which is not convenient for actual operation; [000...
