Gun-type bedside fiberoptic bronchoscope

Abstract

The invention discloses a gun-type bedside fiberoptic bronchoscope including a handheld gun body and a fiberoptic bronchoscope body; the handheld gun body is provided with a first connector at the head and a control box at the tail, the control box is provided with a second connector in threaded connection with the first connector, and the second connector communicates with a pipeline side the fiberoptic bronchoscope body; and the inside of the handheld gun body is provided with a three-position four-way directional control valve, and the first connector, a flushing tube, a medicine injectiontube and a suction tube respectively communicate with a channel of the three-position four-way directional control valve. The fiberoptic bronchoscope is operated by virtue of the handheld gun body, sothat functions of flushing a focus of infection with saline, injecting a medicine to the focus of infection and attracting the focus of infection to perform tissue biopsy and sampling and the like may be simultaneously achieved, and all the functions may be achieved by one-hand operation; and the overall operation is realized under a visual condition, so that the operation difficulty is low.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a gun-type bedside bronchoscope. Background technique [0002] Fiber bronchoscope (referred to as fiber bronchoscope) is an instrument for diagnosing bronchial diseases by using a light guide composed of tens of thousands of highly transparent glass or acrylic resin drawn into very thin fibers. Its lumen is small, soft and bendable, with strong light guiding ability, high brightness, and clear vision. It can easily enter the trachea from the oral cavity or nasal cavity to the mouth of each bronchial segment. Doctors can observe the trachea, left and right bronchi under direct vision. For openings and mucous membranes, you can use a small brush to gently press and brush suspicious mucous membranes several times. The brushed objects can be used for smear staining and culture inspection; or inject a small amount of normal saline to rinse and extract for smear and culture...

Problems solved by technology

[0003] The existing bronchoscope has single function. After the head of the bronchoscope is inserted into the lesion, due to the complex environment in the patient's body, it is difficult for the bronchoscope to obtain all the images. When encountering obstacles, it is not easy to insert
