Problems solved by technology

[0006] 2. Inside the vertebral body fracture, the relative pressure formed by the ruptured vertebral body on the balloon is small or uneven, and the balloon will choose to expand to the place with less pressure during the compression expansion process, which is very effective. It may aggravate the degree of fracture injury at the broken part, and even cause re-fractu

Abstract

The invention discloses a balloon catheter for vertebral expansion and a preparation method of the balloon catheter for vertebral expansion. The preparation method includes steps: S10, performing injection moulding to obtain a Y-shaped catheter body and a catheter cap; S20, adhering a supporting guide wire and a guide wire cap; S30, preparing a balloon, marking an outer tube, enabling the balloon to sleeve one end of the outer tube, enabling a tube sleeve to sleeve the joint of the outer tube and the balloon, and firmly welding the tube sleeve; S40, connecting the outer tube with the Y-shaped catheter body; S50, connecting the inner tube with the catheter cap of the Y-shaped catheter body; S60, mounting radiopaque marks on the inner tube; S70, connecting the Y-shaped catheter body with the catheter cap; S80, sealing a far end of the balloon; S90, inserting the supporting guide wire into the inner tube, mounting a needleless connector at a third connection port, and evacuating the balloon to finish assembly. Due to synchronous execution of multiple procedures, production efficiency is improved.

Description

technical field [0001] The invention relates to the field of medical device design and its preparation technology, in particular to a vertebral body expansion balloon catheter and a preparation method thereof. Background technique [0002] Vertebral fractures can lead to dysfunctional pain that lasts for several months. This pain can cause the patient to lose labor and exercise capacity, and can quickly cause loss of limb function, atelectasis and pneumonia, deep vein thrombosis and pulmonary embolism, etc. A fatal complication, vertebral compression fractures were also the cause of many elderly people's inability to take care of themselves and loss of independent living ability in the past. The use of a large amount of drug treatment often causes drug side effects and drug dependence, and most patients do not accept or cannot tolerate surgical treatment. There are currently two main surgical approaches for this condition. [0003] The first is that the clinical full name ...
