Definitions

• the present invention relates to a balloon catheter for backbone treatment, and more particularly, to a balloon catheter for reducing a treatment time and preventing an injected bone cement from stimulating and destroying nerves during quick setting.
• catheter refers to a tube type tool and is formed of synthetic resin, plastic rubber, latex, silicon, metal, etc.
• Catheter is comprised of a long injection tube 10 and a balloon inflation part 20 connecting to an end of the injection tube 10 and inflating an interior of the backbone.
• an insertion hole 40 is first provided up to an inner side of the backbone using a fine drill 30 (SlO).
• the balloon inflation part 20 is inserted into the backbone through the insertion hole
• a high-pressure inflation gas or inflation liquid 50 is injected (S30), thereby gradually inflating an interior of the backbone and securing a predetermined cavity in the backbone.
• the balloon inflation part 20 is withdrawn from the insertion hole 40 (S40).
• Bone cement 60 is injected into the cavity using a separate tool 70 and is quickly set for bone reinforcement (S50). Thus, any more backbone collapse is prevented.
• the backbone reinforcement requires several works of providing the insertion hole 40 in the backbone by the drill 30, inserting the balloon inflation part 20 into the insertion hole 40 of the backbone, injecting the inflation gas or inflation liquid 50 into the inserted balloon inflation part 20 to thereby inflate the balloon inflation part 20, withdrawing the balloon inflation part 20 from the insertion hole 40 of the backbone, and injecting a quick-setting bone cement 60 into the cavity using the separate tool 70.
• the present invention is directed to a balloon catheter that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
• An object of the present invention is to reduce the number of instruments necessary for medical treatment and greatly reduce a work time for treatment.
• Another object of the present invention is to prevent bone cement injected into the backbone from getting in direct contact with nerves, thereby reducing a concern about destroying patient's nerves due to high temperature generated while quick setting.
• a balloon catheter for backbone treatment in which a cavity is secured to reinforce the backbone suffering a fracture or a compression fracture by providing a predetermined insertion hole in front of the backbone and inflating an interior of the backbone by insertion into the insertion hole.

• FIG. 13 is a flowchart illustrating a procedure of reinforcing the backbone using the balloon catheter according to the present invention.
• the balloon catheter for backbone treatment includes a cement injection tube 100 and a balloon inflation part 200.
• the cement injection tube 100 is of a long tube type formed of Steel UnStain (SUS).
• the balloon inflation part 200 is of a roughly "8"-shaped rubber and is combined by a combiner 300 with the cement injection tube 100.
• a combiner 300a such as a screw is installed at an end of the cement injection tube 100.
• a combiner 300b is installed at one end of the balloon inflation part 200 in such a manner that it faces the cement injection tube 100. So, they can be assembled and disassembled from each other.
• the combiner 300 can use various types of combiners that are not disclosed in the present invention.
• the balloon inflation part 200 is formed such that a rear inflation part is more inflated than a front inflation part.
• the rear inflation part is formed about 1.2 times to 1.6 times greater in size than the front inflation part.
• An extension tube 400 having a predetermined diameter is installed inside the balloon inflation part 200 to communicate with the cement injection tube 100, crossing an interior of the balloon inflation part 200 from the combiner 300b of the balloon inflation part 200.
• the extension tube 400 has one or more outlets 410.
• an insertion hole 40 is provided to have a predetermined depth in a backbone portion intended for treatment, using a tool such as a drill 30 (Step 110).
• the balloon inflation part 200 of the balloon catheter is inserted into the insertion hole 40 provided in the backbone (S 120).
• a quick-setting bone cement 60 is injected at high pressure through the cement injection tube 100 (S 130).
• the balloon inflation part 200 is filled with the injected bone cement 60. If the bone cement 60 is excessively filled, the balloon inflation part 200 is inflated while being filled with the bone cement 60.
• a fractured backbone portion is gradually made stand while reinforced, and the injected bone cement 60 is quickly set and hardened within the backbone together with the balloon inflation part 200. If so, the cement injection tube 100 combined by the combiner 300 is separated from the balloon inflation part 200 (S 140).
• the balloon inflation part 200 While the balloon inflation part 200 is inflated, the rear inflation part is more inflated than the front inflation part and hence, a rear part of the backbone is more made stand than a front part and even a work can be performed efficiently.
• a predetermined cavity is secured in the interior of the backbone without separately injecting the inflation gas or inflation liquid 50 for inflating the balloon inflation part 200. Also, there is no need for separately providing an instrument for inflating the balloon inflation part 200 and an instrument for injecting the bone cement 60 and hence, a surgical operation is simple and a work time is reduced.
• the present invention is very useful in that bone cement is injected while inflating a balloon inflation part without injecting a separate inflation air or inflation liquid, thereby greatly simplifying a work and reducing a surgical operation time. Also, a heat generated from the injected bone cement during quick setting is cut off by the balloon inflation part and hence, there is no concern about nerve destruction.
