Abstract

The invention discloses a medical tube and a cavity flusher. Wherein the medical tube comprises a tube body. The tube wall of the tube body is provided with at least one spiral portions extending along the axial direction of the tube body, and the spiral portion has a thread gap penetrating the wall of the tube; a covering body that is flexible to cover and seal the spiral portion of the tubular body. The medical tube has the characteristics of materials, which can ensure the flexibility of the medical tube with good applicability to a complicated tissue environment.

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. [0004] In order to meet the above-mentioned needs in the field of cavity irrigation, various medical tubes have been invented, for example, medical tubes with rigid structure, plastic st...
