Problems solved by technology

[0017] Therefore, whenever an operation is performed, the existing balloon catheter 1 needs to insert the guide wire 5 into the inner tube 4, which is cumbersome, and the inner tube 4 and the guide wire 5 complicate the structure of the balloon catheter 1.
[0018] Moreover, there is also the following problem in the conventional balloon catheter 1: when high-pressure air is supplied into the balloon 2 during surgery, the inner tube 4 and the balloon 2 expand in the longitudinal direction due to the pressure in the balloon 2, and the above-mentioned Airbag 2 cannot fully inflate radially outward
The small expansion size of such balloon 2 has the problem of reducing the space for injecting medical cement in the surgical part

Embodiment Construction

[0037] For various embodiments of the balloon catheter of the present invention, reference is made to Figure 3 to Figure 6 Make the following description. In the following description, the same reference numerals are used for the same components as those mentioned in the prior art for easy understanding.

[0038] Such as image 3 As shown, the balloon catheter 30 in the first embodiment of the present invention includes: an outer tube 3 , a rigid rod 31 , a balloon 2 , a marker 6 and a main body 32 .

[0039] Wherein, the above-mentioned rigid rod 31 is stuffed into the above-mentioned outside tube 3 along the length direction of the above-mentioned outside tube, and makes it have a certain gap (or gap) with the outside of the above-mentioned outside tube 3 . Further, the front end and the rear end of the rigid rod 31 protrude outward from the outer tube 3 and are of a solid type.

[0040] One end of the airbag 2 is sealed and fixed around the front end of the rigid rod 31...

Abstract

A balloon catheter is disclosed. The balloon catheter includes an outer tube (3), a solid rigid rod (31), a balloon (2), markers (6) and a body unit (32). The rigid rod (31) is inserted into the outer tube such that a gap is defined between the rigid rod and the inner surface of the outer tube (3). The front and rear ends of the rigid rod (31) extend outwards from the outer tube (3). The front end of the balloon (2) is fastened to the front end of the rigid rod (31). The rear end of the balloon (2) is fastened to the front end of the outer tube (3). The markers (6) are fastened to the rigid rod (31) in the balloon (2) at opposite positions spaced apart from each other. The body unit (32) is fastened to the rear end of the outer tube (3) and supports the rigid rod (31) and prevents it from moving forwards.

Description

technical field [0001] The present invention relates to a medical balloon catheter, and more specifically, to a balloon catheter for injecting medical cement into the damaged part by dilating the inside of the damaged part in order to restore a fractured, necrotic, or dented spine in the human body. Background technique [0002] In general, surgery on a damaged spine can be performed by inserting a tubular catheter near the patient's damaged spine and injecting medical cement. When performing an operation using the above-mentioned catheter for treating the spine, it is very important to sufficiently expand the damaged portion in the spine to be operated so that an appropriate amount of medical cement can be injected into the expanded portion. [0003] figure 1 A brief cross-sectional view of a typical balloon catheter is shown, figure 2 A schematic sectional view of a conventional balloon catheter and a restorer for spinal surgery connected to the balloon catheter is show...
