Medical composite hollow fiber tube and medical intervention equipment

Abstract

The invention provides a medical composite hollow fiber tube. The medical composite hollow fiber tube comprises an inner layer, an outer layer and a middle reinforced layer, wherein the inner layer and the outer layer are hollow and coaxially nested, and the middle reinforced layer is arranged between the inner layer and the outer layer and comprises an axial telescopic knitting layer and reinforced fibre; the axial length of the middle reinforced layer is smaller than the axial length of the inner layer and the outer layer. Due to the specific structure of the medical composite hollow fiber tube, not only can the pushing performance and the support force of the tensile strength of the tube be ensured, but also the bendability and flexibility of the tube can also be greatly improved; medical intervention equipment manufactured by using the medical composite hollow fiber tube has better bending performance, so that it is ensured that the medical intervention equipment can smoothly pass through circuitous and tortuous blood vessels without folds; the medical intervention equipment is provided with a developing function through the arrangement of a developing ring so as to meet comprehensive performance requirements of the medical intervention device of minimally invasive blood vessels to the outer tube of a conveyor system.

Description

technical field [0001] The invention relates to the medical field, in particular to a medical composite hollow fiber tube and an interventional medical device. Background technique [0002] Vascular microtrauma interventional surgery has the advantages of less bleeding, less trauma, fewer complications, quick postoperative recovery, safety and reliability, etc., which can greatly reduce the pain suffered by patients. With the development of minimally invasive vascular interventional surgery technology, the performance requirements for vascular interventional medical devices are getting higher and higher. The traditional hollow fiber structure mainly has disadvantages such as low tensile strength, poor bending performance, poor pushability, poor flexibility, and no development, which cannot meet the comprehensive performance requirements of the outer tube of the conveyor system. [0003] It is extremely urgent in this technical field to develop a pipe material and an interve...
