Description

Balloon catheter system with bracket for vertebroplasty
Technical Field
The invention relates to the field of medical instruments, in particular to a balloon catheter system with a bracket for vertebroplasty.
Background
Vertebroplasty and kyphoplasty are recognized minimally invasive treatment options for osteoporotic vertebral compression fractures. However, the procedural disadvantages of these surgical techniques are incomplete fracture reduction or significant loss of recovery height, respectively, after balloon deflation prior to bone cement injection.
To avoid loss of height after balloon deflation, it is therefore desirable to design a vertebral body stenting procedure using expandable scaffolding structures similar to vascular stents, with specially designed vertebral body stents that can be additionally or transcorneally implanted and expanded within the vertebral body using an inflatable balloon.
Disclosure of Invention
It is an object of the present invention to provide a vertebroplasty stented balloon catheter system that uses a vertebral stent with the stent retained within the newly created vertebral body cavity so that the balloon can be removed after deflation while preventing collapse of the vertebral body, thereby restoring and maintaining physiologic vertebral body height and shape under ideal conditions.
In order to solve the technical problems, the invention adopts the following specific technical scheme:
a vertebroplasty stented balloon catheter system, the system comprising: a probe, a vertebral body dilatation balloon catheter, and a vertebral body stent; the probe comprises a probe handle and a probe part; the vertebral body expansion balloon catheter comprises a catheter, a Y-shaped connector, a limiting marker ring, a balloon and a connector; one end of the catheter is connected with the Y-shaped connector, the other end of the catheter is connected with the balloon, the probe penetrates through a joint on the Y-shaped connector and the catheter and then extends into the balloon, and two limiting mark rings are arranged in the middle of the catheter; the interface is connected with a one-way valve; the vertebral body bracket wraps the balloon; the balloon is expanded to drive the vertebral body support to expand, and the vertebral body support is expanded; when the saccule contracts, the vertebral body support keeps an expanded state, and the expanded vertebral body support is remained in a body to form a cavity.
Furthermore, the original state of the vertebral body support is a cylindrical net-shaped structure, and the expanded state of the vertebral body support is a cage-shaped structure.
The invention has the following beneficial effects: the balloon catheter system with the bracket for vertebroplasty disclosed by the invention uses a specially designed vertebral bracket, can be implanted and expanded in a vertebral body, can completely reduce the compression fracture of the vertebral body, and helps to maintain the recovered height through the bracket. Compared with kyphoplasty, the balloon catheter system with the bracket for vertebroplasty of the invention has the advantages that the height loss after balloon contraction is obviously reduced. The balloon catheter system with the bracket for the vertebral body forming is characterized in that a balloon is wrapped on a vertebral body bracket, and the balloon is expanded to drive the vertebral body bracket to expand so as to open the vertebral body bracket; when the saccule contracts, the vertebral body support keeps the opening state, the opened vertebral body support is remained in the body to form a cavity, and the vertebral body support forms a cage-shaped structure, so that the leakage can not be caused in the bone cement injection process, and the physiological vertebral body height and shape can be recovered and kept.

FIG. 3: structure diagram of vertebral body support.
Detailed Description
The technical scheme of the invention is further explained in detail by combining the drawings and the specific examples.
1-3, a vertebroplasty stented balloon catheter system, the system comprising: a probe 1, a vertebral body expansion balloon catheter 2 and a vertebral body bracket 3; the probe 1 comprises a probe handle 11 and a needle rod part 12; the vertebral body expansion balloon catheter 2 comprises a catheter 22, a Y-shaped connector 26, limit mark rings 23 and 24, a balloon 25 and a port 21; one end of the catheter 22 is connected with a Y-shaped connector 26, the other end of the catheter 22 is connected with a saccule 25, the probe 1 penetrates through a joint on the Y-shaped connector 26 and the catheter 22 and then extends into the saccule 25, and the middle part of the catheter 22 is provided with two limiting mark rings 23 and 24; the interface 21 is connected with a one-way valve; the vertebral body bracket 3 is wrapped with the balloon 25; the balloon 25 expands to drive the vertebral body support 3 to expand and to open the vertebral body support 3; when the saccule 25 contracts, the vertebral body support 3 keeps an expanded state, and the expanded vertebral body support 3 is left in the body to form a cavity; the original state of the vertebral body support 3 is a cylindrical reticular structure, and the expanded state of the vertebral body support 3 is a cage-shaped structure.
The working principle of the balloon catheter system with the bracket for vertebral body shaping is as follows: because the vertebral body support 3 is wrapped on the balloon 25, the balloon 25 is expanded to promote the expansion of the vertebral body support 3 and to open the vertebral body support 3; the saccule 25 is contracted and pulled out of the body, the expanded vertebral body bracket 3 is left in the body to form a cavity, and finally bone cement is injected, because the vertebral body bracket 3 forms a cage-shaped structure, leakage cannot be caused in the injection process of the bone cement, and the physiological vertebral body height and shape can be recovered and maintained.
However, those skilled in the art should realize that the above embodiments are illustrative only and not limiting to the present invention, and that changes and modifications to the above described embodiments are intended to fall within the scope of the appended claims, provided they fall within the true spirit of the present invention.
