Description

Technical Field

[0001] The utility model relates to the technical field of specimen collection devices, in particular to a specimen collection device for shearing an endoscopic cell brush. Background Art

[0002] Quantitative cellular DNA analysis is a new, automated, standardized, and intelligent method for identifying tumor cells. It primarily uses a DNA ploidy analysis system to determine the physiological and pathological states of cells by measuring the DNA content or ploidy within the nucleus after special staining. It is highly helpful for early detection of tumors because, during the process of cell malignancy, the genetic material DNA content changes before the cell morphology, thereby reducing the rate of missed diagnoses and effectively improving the sensitivity and accuracy of cancer screening.

[0003] Cellular DNA quantitative analysis is mainly used in the detection of exfoliative cytology, fine needle aspiration (FNA) specimens, and tissue prints. Among them, cellular DNA quantitative analysis technology can be used to diagnose tumors early by detecting endoscopic brush specimens: such as bronchoscope brushes, gastroscope brushes, esophagoscope brushes, colonoscope brushes, cystoscopic brushes, percutaneous pleural brushes, etc. DNA quantitative analysis and detection work provides a large amount of reliable diagnostic basis for clinical treatment.

[0004] Electric shears are handheld tools powered by an electric motor, which drives the working head through a transmission mechanism to perform shearing operations. Using electricity to replace manual labor, they provide high shearing force and are widely used in applications such as crop pruning and shearing cloth, paper, and plastic. Cytology brushes are normally retracted within a plastic tube, but when opened, they can extend approximately 2 cm for brushing. After brushing, the shears cut the endoscopic cytology brush, retaining the specimen in a specimen bottle.

[0005] Nowadays, cell brushes are cut manually using ordinary scissors in clinical practice. However, cell brushes are made of metal, which is not easy to cut and inconvenient for clinical use. A second person is required to hold the scissors to cut the cell brush, which takes up manpower and wastes resources. The cut cell brush is easy to fall to a position outside the specimen bottle. The scissors have no fixed position and are easy to fall or the tip of the scissors may pierce the staff. In addition, the scissors used in clinical practice should be disinfected after use by one person, and are difficult to perform terminal disinfection.

[0006] There may already be technical means to solve the above problems in the existing technology, but this case intends to provide an alternative or replacement technical solution. Utility Model Content

[0025] In order to solve the problem that the current clinical cytology brush cutting is done manually using ordinary scissors, but the cytology brush is made of metal, which is not easy to cut and inconvenient for clinical use. When cutting the cytology brush, a second person is required to hold the scissors to cut, which takes up manpower and wastes resources. The cytology brush is easy to fall to a position outside the specimen bottle. The scissors have no fixed position and are easy to fall or the tip of the scissors may stab the staff. In addition, the scissors used in the clinic should be used by one person and disinfected once, which is difficult to perform terminal disinfection. The present technical solution is designed. The detailed technical solution is as follows;

[0026] See also Figure 1-4 A specimen collection device for cutting an endoscopic cytology brush 3 comprises a base 1, an upper wall surface of the base 1 is provided with a U-shaped chute 21, one end of the U-shaped chute 21 is placed on a specimen bottle 2, a cytology brush 3 is provided above the specimen bottle 2, a shearing structure is provided on the base 1 and on one side of the specimen bottle 2, and a storage structure is provided on the base 1 and on the other side of the specimen bottle 2;

[0027] It should be noted that the base 1 is made of metal and has a large weight, so that the device can be stably installed on the operating table;

[0028] Specifically, the shearing structure includes a fixed nut 4, which is mounted on the base 1, and a fixed rod 5 is inserted on the fixed nut 4, which is inserted into the fixed nut 4 through a thread, and a movable sleeve 6 is movably mounted on the fixed rod 5, and a first fixing bolt 7 is inserted through a thread on the side wall of the movable sleeve 6, one end of the first fixing bolt 7 is movably fitted on the fixed rod 5, and an extension column 8 is installed on the side wall of the movable sleeve 6, and a fixed semicircular clamp 9 is installed at one end of the extension column 8, and a movable semicircular clamp 10 is movably fitted on the fixed semicircular clamp 9, and the fixed semicircular clamp 9 and the movable semicircular clamp 10 are connected by a threaded assembly, and an electric shearing pliers 11 is movably inserted between the fixed semicircular clamp 9 and the movable semicircular clamp 10, and the electric shearing pliers 11 matches the cell brush 3. A limiting assembly is also installed on the fixed rod 5;

[0029] The cam 6 is adapted to move the blade 11 upwards and downwards, so that the cam 6 can be moved upwards and downwards, thereby ensuring that the cam 6 is in a position to move freely in the cam 6 and to move freely in the cam 6. The fixing rod 5 is rotated to align the electric pliers 11 with the placement area of ​​the specimen bottle 2, that is, the U-shaped slide 21 part, and then the first fixing bolt 7 is rotated until one end of the first fixing bolt 7 is in contact with the fixing rod 5, so that the position of the movable sleeve 6 is fixed, and the position of the electric pliers 11 is fixed. The operator places the specimen bottle 2 in the U-shaped slide 21 and moves the specimen bottle 2 horizontally to the end of the U-shaped slide 21. The operator's hand touches the blade end of the electric pliers 11 to prevent injury to the hand. The U-shaped slide 21 also plays the role of positioning the specimen bottle 2 and aligning the bottle mouth of the specimen bottle 2 with the blade part of the electric pliers 11.
