Combined supporting guide wire and vertebral body expanding balloon catheter

Abstract

The invention discloses a combined supporting guide wire and a vertebral body expanding balloon catheter using the combined supporting guide wire. The combined supporting guide wire comprises a guidewire and a sleeve, wherein the guide wire is accommodated in the sleeve in a slidable mode, the sleeve comprises a linear section and a flexible bent section, the flexible bent section is kept in a linear shape when the guide wire is inserted, and a bent shape is recovered when the guide wire is pulled out. The combined supporting guide wire further comprises a control handle, wherein one end of the guide wire is fixedly arranged on the control handle, the control handle and the sleeve are connected in a slidable or threaded mode. The control handle is marked with the bending degree of the flexible bent section. A balloon can be driven to be bent in the vertebral body. The invention further discloses the vertebral body expanding balloon catheter. The vertebral body expanding balloon catheter comprises the balloon, an outer tube, an inner tube and the combined supporting guide wire, balloon bending is achieved and is controllable, and a better vertebral body expanding effect can be also achieved by adopting a unilateral admission passage during balloon catheter expanding.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a combined support guide wire and a vertebral body expansion balloon catheter. Background technique [0002] Osteoporotic vertebral compression fractures can cause dysfunctional pain that lasts for several months. This pain can cause the patient to lose labor force and exercise capacity. Long-term bed rest will lead to atrophy of limb muscle tissue, bedsores, and aggravation of osteoporosis. And vertebral body compression fractures are often also one of the reasons why many elderly people cannot take care of themselves and lose the ability to live independently. When choosing surgical methods such as open spinal internal fixation, patients may have a higher risk of surgical complications due to their older age, so it is not suitable and difficult to accept this type of surgical treatment. There are currently two main surgical approaches for this condition. [0003] The first is t...

Problems solved by technology

[0004] In clinical practice, PKP generally adopts the method of bilateral percutaneous vertebral balloon expansion. For patients, the trauma will increase and the economic burden will increase. The more cumbersome the operation process, the longer the operation time. , the radiation intake will increase, the health damage will be greater, and the physical strength will be higher
