Abstract

The invention relates to the technical field of medical devices, in particular to forming equipment for a medical reinforced catheter and a forming method thereof. The forming equipment comprises a first extruder, a torsion machine, a second extruder and a dragger which are successively arranged along the conveying direction of a formed core strip and are independent. The first extruder comprisesa first channel and a first cavity along the conveying direction, the first channel penetrates the first cavity, and the first extruder is used for forming an inner annular layer; the torsion machineis used for winding a spring to the outer wall of the inner annular layer to form an elastic part, the second extruder is provided with a second channel and a second cavity formed along the conveyingdirection, and the second channel penetrates the second cavity; the second extruder is used for forming an outer annular layer, the core strip moves linearly under the action of the dragger by arranging the first extruder, the torsion machine, the second extruder and the dragger to successively form the inner annular layer, the elastic part and the outer annular layer so as to finally form the medical reinforced catheter. The medical reinforced catheter meets the using demands of high precision, high toughness and high flexibility.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a molding device and a molding method for a medical reinforced catheter. Background technique [0002] The medical reinforced catheter plays a key role in the operation. The circumference specification of the medical reinforced catheter is generally in the range of 8mm-24mm. The medical reinforced catheter needs to have the characteristics of high precision, high toughness, and high flexibility to meet the surgical needs. However, the traditional production of such high-precision, high-willed, and high-flexibility medical reinforced catheters has high production costs, relatively large production difficulties, and low production pass rates, resulting in high costs for surgical consumables. Contents of the invention [0003] In order to overcome the disadvantage of high production cost of medical reinforced catheters in the prior art, the purpose of the present invention...
