Special-shaped vertebral body expansion balloon catheter

Abstract

The invention provides a special-shaped vertebral body expansion balloon catheter, which relates to a surgical instrument used for treating compression fracture of the vertebral body and comprises a special-shaped expandable balloon, an inner catheter, an outer catheter, a Y-shaped handle, a development mark, a support wire and a support wire handle, wherein the inner catheter is arranged and inserted in the outer catheter, the back part of the outer catheter is arranged and inserted into the Y-shaped handle in a sealed way, the special-shaped expandable balloon is arranged at the front part of the outer catheter in a sealed way, the development mark is arranged in a position of the inner catheter positioned inside the special-shaped expandable balloon, the support wire is formed in the support wire handle through injection molding, is inserted and arranged in the inner catheter through the Y-shaped handle, and is used for supporting, and the inner catheter is prevented from deforming. The special-shaped expandable balloon consists of an expandable balloon and reinforcing ribs made of fiber, and the reinforcing ribs are formed inside the expandable balloon through injection molding. The reinforcing ribs of the special-shaped expandable balloon adopt carbon fiber, macromolecular polyethylene fiber, memory array wires or plastic nylon materials.

Description

technical field [0001] The special-shaped vertebral body expansion balloon catheter of the invention relates to a surgical instrument for treating vertebral body compression fractures. Background technique [0002] Pain caused by vertebral compression fractures has become a serious problem faced by patients, their families and even clinicians, and patients have lost their mobility due to long-term pain. Traditional treatment methods for vertebral compression fractures include bed rest, analgesic drugs and the application of braces, but these methods relieve pain slowly. Long-term pain will limit the patient's daily activities, and gradually lead to a decline in self-care ability and loss of self-confidence. [0003] It was not until the emergence of vertebroplasty that this problem was ideally solved and gradually applied to clinics. However, the shortcomings of some instruments themselves are gradually emerging. As the most important tool in the process of vertebroplasty: ...

Problems solved by technology

[0003] It was not until the emergence of vertebroplasty that this problem was ideally solved and gradually applied to clinics. However, the shortcomings of some instruments themselves are gradually emerging. As the most important tool in the process of vertebroplasty: vertebral body Dilated balloon catheters often have problems such as insufficient distraction force, poor controllability, easy rupture of the balloon, and difficulty in taking out intraoperative fractures.
