Vertebral oriented dilated balloon catheter

Abstract

The invention discloses a vertebral oriented dilated balloon catheter which is used in the percutaneous vertebroplasty in the field of orthopedic medical devices. The vertebral oriented dilated balloon catheter comprises a catheter, wherein a Y-shaped connector is connected to one end of the catheter, and a balloon is connected to the other end of the catheter; a probe extends into the balloon after passing through a joint of the Y-shaped connector and the catheter, and a ray label is arranged on the head of the probe; an oriented casing is sleeved outside the catheter, and a forward-protruding oriented separation blade is arranged on the head of the oriented casing; and the oriented separation blade is positioned at the outer side of the balloon. According to the vertebral oriented dilated balloon catheter with the structure, the balloon can dilate towards a preset dilation resetting direction, so that the degree of fracture injury on a vertebral body breakage part cannot be sharpened, and re-fracture is avoided.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to a vertebral body expansion balloon catheter used in percutaneous puncture vertebroplasty. Background technique [0002] The incidence of vertebral compression fractures is high in the elderly population. The degree of collapse and compression of each part of the vertebral body at the fracture site is different. For the part with a high degree of compression, it needs to be opened and reduced, and bone cement and other fillers should be injected for filling. After the bone cement solidifies, it can increase the strength and stability of the vertebral body, which ensures that the restored vertebral body will not be compressed again, and will not lose the height of the vertebral body and compress the nerves again. [0003] Vertebral body expansion balloon catheter is one of the commonly used devices for treating vertebral body compression fractures. For its structure, see ...

AI Technical Summary

Problems solved by technology

[0005] The shortcoming of the vertebral body expansion balloon catheter with the above-mentioned traditional structure is: the balloon 5 will expand non-directionally around after injecting a certain volume of contrast agent, and inside the fractured vertebral body, the fractured vertebral body will be opposite to the balloon 5. The relative pressure formed is small and not uniform, and the balloon 5 will choose to expand to the place with less pressure during the process of expansion under pressure, which is very likely to aggravate the degree of fracture damage at the broken part, and even cause re-fracture, thereby aggravating the patient condition
