Embodiment 1

[0047] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a novel flushing cleaning brush used under a bronchoscope of the present invention. A flushing cleaning brush used under bronchoscopy, the flushing cleaning brush includes a handle 1, a transmission wire 2, a water injection device 3, an outer sheath tube 4, and a brush head 5; one end of the transmission wire 2 is connected to the handle 1 , the other end is connected to the brush head 5; the water injection device 3 is pierced on the transmission wire 2; the distal end of the water injection device 3 is connected to the outer sheath 4.

[0048] Please refer to figure 2 , figure 2 It is a partially enlarged structural schematic diagram of the water injection device 3 . The water injection device 3 includes a sealing cap 31, a sealing ring 32, a butt joint 33, a reversing pipe 34, a water injection pipe 35, a water injection cap 36, and a drainage tube 37; the sealing cap 31 is connected t...

Embodiment 2

[0058] Please refer to Figure 5 , Figure 5 It is a schematic diagram of the local structure of the transmission wire 2. This embodiment is basically the same as Embodiment 1, the difference is that the transmission wire 2 in this embodiment is covered with a film tube 6, and the purpose of passing through the film tube 6 is to increase the lubricating effect and reduce friction, so that the handle 1. It can accurately control the forward and backward movement and rotation of the brush head 5, which is convenient for cleaning secretions at different angles and avoids cleaning blind spots.

Embodiment 3

[0060] Please refer to Figure 6 , Figure 6 is a schematic diagram of the structure of the flushing hole 411. This embodiment is basically the same as Embodiment 1, except that the section of the flushing hole 411 in this embodiment is a fan-shaped surface, and the small end face of the flushing hole 411 communicates with the inner passage of the outer sheath tube 4, and the flushing hole 411 The large end surface communicates with the outside world. The small end surface of the flushing hole 411 is mainly responsible for forming the impact force of the water flow required for cleaning. The large end surface of the flushing hole 411 is mainly responsible for the flushing area. Under this structure, the flushing area is large and the cleaning effect is good. Avoid cleaning blind spot.

Abstract

The invention relates to a flushing clearing brush of a bronchoscope. The flushing clearing brush comprises a handle, conduct wires, an injection device, outer sheath, and a brush head; a handle is connected with one end of the conduct wires, the brush head is connected with the other end; the injection device is threaded on the conduct wires; the outer sheath is connected with the distal end of the injection device. The flushing clearing brush of the bronchoscope has the advantages that the flushing clearing brush of the bronchoscope has the function of rinsing and clearing, the flushing clearing brush is easy to operate, less hours and effort are expended, the clearing is thorough, the clearing effect is good, for medical personnel, the work efficiency is increased, for patients, security troubles are cleared, and broad application prospect is achieved in clinical generalization.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a flushing cleaning brush used under a bronchoscope. Background technique [0002] With the development of medicine, the application of bronchoscopy in the diagnosis and treatment of respiratory diseases has become increasingly widespread. Through bronchoscopy, various diseases of the trachea, bronchi, and segmental bronchi can be diagnosed, and the diagnosis of tumors, tuberculosis, and endobronchial hemorrhage can be clarified. It can perform various interventional treatments in the bronchus, and plays a very important role in the diagnosis and treatment of respiratory diseases and the rescue of critically ill patients. However, the following problems are often present during bronchoscopy: [0003] Clinically, airway stents such as silicone stents and metal stents are often implanted during bronchoscopy. Further treatment gained time. Because the stent covers the...
