Abstract

The invention discloses a medical pipe and a sinus tract rinser. The medical pipe comprises bending mechanisms, outer pipes, an inlet end and an outlet end, wherein each bending mechanism comprises aplurality of moving units which are in series connection and are provided with passages, the angle between every two adjacent moving units can change in discretionary direction, and the passages of every two adjacent passages communicate; each outer pipe circumferentially surrounds the corresponding bending mechanism, and generates shape changes along with the shape changes of the corresponding bending mechanism; the inlet end is located at one end of the outer pipes to allow fluid to enter; and the outlet end is located at one ends of the outer pipes to allow fluid to drain. When the medicalpipe provided by the invention is used, on one hand, the medical pipe can be flexibly suitable for different use environment, on the other hand, the damage to the medical pipe due to shape changes canbe effectively reduced, and the service life of the medical pipe can be prolonged.

Description

technical field

[0001] The invention relates to the medical field and the field of cavity flushing, and more specifically, to a medical tube and a cavity flusher. Background technique

[0002] Existing pipes generally adopt a rigid structure, a plastic structure or an elastic structure. With the development of technology in various fields, tubes with variable shapes are required in many fields to adapt to different scenarios.

[0003] In the field of cavity irrigation, taking the nasal cavity as an example, sinus surgery or treatment is a very common form of treatment in ENT. Due to the narrow space of the nasal cavity, the complex structure, and the great differences between patients, it is sometimes difficult for the operating medical staff to accurately reach the lesion for operation. At present, in the operating room or outpatient room, doctors usually manually bend long and thin metal tubes into different shapes, and then go deep into the patient's nasal cavity for ir...
