Embodiment Construction

[0012] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples.

[0013] Such as Figure 1-3 As shown, a balloon catheter system with a stent for vertebroplasty, the system includes: a probe 1, a balloon catheter for vertebral body expansion 2, and a vertebral body stent 3; the probe 1 includes a probe handle 11 and a needle shaft 12; the vertebral body expansion balloon catheter 2 includes a catheter 22, a Y-shaped connector 26, a limit marker ring 23, 24, a balloon 25 and an interface 21; one end of the catheter 22 is connected with a Y-shaped connector 26, and the other end of the catheter 22 One end is connected with a balloon 25, and the probe 1 is inserted into the balloon 25 after passing through a joint on the Y-shaped connector 26 and the catheter 22, and the middle part of the catheter 22 is provided with two limit marking rings 23, 24; The interface 21 is connected t...

Abstract

The invention discloses a vertebroplasty balloon catheter system with a stent. The vertebroplasty balloon catheter system includes a probe, a vertebral body expansion balloon catheter, and the vertebral body stent; the vertebral body stent wraps a balloon, and the balloon expands to drive the vertebral body stent to expand to open the vertebral body stent; and when the balloon contracts, the vertebral body stent remains in an opening state, and the opened vertebral body stent remains in a body to form a cavity. According to the vertebroplasty balloon catheter system with the stent, the vertebral body stent wraps the balloon, and the balloon expands to drive the vertebral body stent to expand to open the vertebral body stent; when the balloon contracts, the vertebral body stent remains in an opening state, and the opened vertebral body stent remains in the body to form the cavity; and since the vertebral body stent forms a cage-like structure, leakage does not occur during a bone cementinjection process, and the physiological vertebral body height and shape can restored and maintained.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a vertebroplasty balloon catheter system with a stent. Background technique [0002] Vertebroplasty and kyphoplasty are well-established minimally invasive treatment options for osteoporotic vertebral compression fractures. However, procedural disadvantages of these surgical techniques are incomplete fracture reduction or significant loss of recovered height after balloon deflation prior to cement injection, respectively. [0003] In order to avoid the loss of height after balloon deflation, it is necessary to design a vertebral body stent using an expandable scaffold structure similar to a vascular stent. With a specially designed vertebral body stent, an inflatable balloon can be used inside the vertebral body for additional Or implanted and expanded through the vertebral body. Contents of the invention [0004] The purpose of the present invention is to provide a balloon...
