Description

Disposable cell needle brush

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to disposable cell needle brush.

Background

The conventional sampling tool of the bronchoscope comprises a cell brush, a biopsy forceps, a puncture needle and the like. For the visual lesion under the bronchoscope in the bronchial cavity of the central airway, a satisfactory specimen can be obtained under most conditions by using a biopsy forceps and a cell brush; for central airway bronchial extraluminal lesions, a more satisfactory specimen can also be obtained using a puncture needle under airway ultrasound or X-ray guidance. Due to the rise of airway ultrasound and magnetic navigation technologies, how to improve the diagnosis rate of peripheral pulmonary lesions remains a current hotspot and difficulty. For invisible extraluminal lesions under a bronchoscope at the periphery of the lung, the quality of a specimen obtained by a conventional cytobrush and biopsy forceps and the positive rate of clinical diagnosis are remarkably reduced, and a puncture needle cannot easily reach the periphery of the lung due to the hardness and the length of the puncture needle. Therefore, whether the sampling tool can reach the lung peripheral lesion and penetrate the bronchial wall is the key to improve the positive rate of diagnosis, and therefore, a disposable cell needle brush is needed to solve the above problems.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

disposable cell needle brush, including puncture biopsy needle, brush, inner core pipeline, outer tube, syringe connector, brush regulation portion and handle, the link of handle with inner core pipeline fixed connection, install the tip of inner core pipeline the puncture biopsy needle is close to the puncture biopsy needle is provided with the brush, brush regulation portion suit in the inner core pipeline, the brush regulation portion with the brush links to each other, is located the periphery of brush regulation portion is provided with continuously the syringe connector with the outer tube, the syringe connector with the inner core pipeline communicates with each other.

Further, the length of the needle biopsy needle is 5 mm.

Further, the maximum outer diameter of the brush is 1.7 mm.

Further, the length of the brush is 10 mm, and the lengths of the bristles of the brush are sequentially reduced from left to right to form a conical shape.

Further, the handle is annular.

The utility model discloses following beneficial effect has to prior art:

the utility model is provided with the brush adjusting part and the outer sleeve pipe in sequence at the periphery of the inner core pipeline, and the brush adjusting part is used for adjusting and controlling the position of the brush so as to better puncture and sample; the outer sleeve has a protection function and is used for increasing the hardness of the novel puncture needle, so that smooth puncture is facilitated; meanwhile, the syringe connector is arranged, so that liquid samples can be directly collected after the syringe connector is communicated with the puncture biopsy needle, and the operation is simple and rapid; the length and the type of the puncture biopsy needle can pass through a bronchoscope biopsy pore passage, so that an extraluminal tissue specimen is obtained, and the success rate of sampling is increased.

The utility model has the advantages of reasonable design, easy operation and convenient to use make this novel puncture power when having certain hardness stronger, carry out the accuse to the whole length of structure simultaneously, increased the success rate of sample, had very high practicality.
