Abstract
The utility model discloses a balloon catheter for expanding vertebra, which comprises an expansible balloon, a soft external conduit, a soft hollow internal conduit which is installed in the external conduit, an elastic supporting guidewire which is installed in the intanal conduit, and a Y-shaped connecting part; one branch of the Y-shaped connecting parts with the external and internal conduit, and the expansible balloon forms a closing channel; a mark is installed in the expansible balloon on the internal conduit; also a mark is provided on the external conduit. The utility model adopts the support guidewire and soft internal conduit to cooperate, and observes the content and position of the mark to conclude the place of the expansible balloon, which enables the expansible balloon to reach the afflicted part freely.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and is particularly a kind of to the pretreatment unit before the fractured vertebral body importing medium.
Background technology
Vertebral fracture can cause continuing the dysfunction pain of several months, this pain can make patient disability and motor capacity, can promptly cause fatal complication such as the formation of forfeiture, pulmonary atelectasis and pneumonia, deep venous thrombosis of limb function and pulmonary infarction, compression fracture of vertabral body also was the reason that independent living ability could not be taken care of oneself and lose to a lot of life of elderly person in the past.Use a large amount of Drug therapys, usually cause poisonous side effect of medicine and drug dependence, the patient scarcely accepts maybe can not tolerate surgical operation therapy.
Normal at present employing percutaneous vertebroplasty is treated vertebral compression fracture, and it is that pedicle is punctured to fractured vertebral body under C arm power traction is led, and injects fixedly vertebral body of bone cement by puncture needle in vertebral body then.But, the percutaneous vertebroplasty also has certain shortcoming and defect, that is, and on the one hand, injecting bone cement by puncture needle causes bone cement to leak easily, cause multiple complications, on the other hand, this technology can only partly ease the pain, can not recover vertebral height, simultaneously, when injecting bone cement, need bigger pressure, easily the patient is damaged.
For addressing the above problem, there is the inventor to propose a kind of spatial apparatus of formation before bone cement is being injected in the affected part that is used for, disclose a kind of system with expandable bodies treatment fracture or sick bone as Chinese invention patent ublic specification of application No. 1557257 (on December 29th, open day), this system comprises: one first lead sheath; One first expandable bodies, this expandable bodies has the state that subsides, be used for space in the insertion of first lead sheath is described, and can be from collapsed mode inflation becoming swelling state, so that compacting cancellous is to form a cavity in interior space, this system also comprises: one second lead sheath, first and second lead sheaths are suitable for providing the independent and isolated passage that enters bone; One second expandable bodies, this expandable bodies has the state that subsides, and is used for space in the insertion of second lead sheath is described, and can become swelling state from the collapsed mode inflation, so that compacting cancellous is to form a cavity in interior space; And wherein first expandable bodies and second expandable bodies are suitable for forming the cavity with ideal form and size when their swelling state.The shortcoming of this device is, for the independent and isolated passage that is suitable for entering bone is provided, has used lead sheath, makes the patient bear some unnecessary miseries, needs to use two expanders just can make cavity reach desired shapes and size simultaneously.
The utility model content
The technical problems to be solved in the utility model provides a kind of vertebral body expansion of balloon catheter that can form cavity in fracture is subsided vertebral body.
For solving the problems of the technologies described above, this utility model vertebral body expansion of balloon catheter, comprise a balloon-expandable, the rubber-like that also comprise soft outer catheter, be placed in hollow inner catheter soft in the outer catheter, is placed in the inner catheter supports seal wire and Y type link; Branch of Y type link and outer catheter, inner catheter and balloon-expandable constitute a closed channel.
The position that is positioned at balloon-expandable on inner catheter is provided with sign.
Outer catheter is provided with labelling.
This utility model is owing to adopt to support seal wire and soft inner catheter matches, and by observing the position of sign and mark position deduction balloon-expandable, makes balloon-expandable can arrive the affected part freely.
Description of drawings
Fig. 1 is this utility model unused state sketch map;
Fig. 2 is this utility model user mode sketch map;
Fig. 3 is this utility model Y type link generalized section;
Fig. 4 is the shape sketch map that supports seal wire in this utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.
This utility model vertebral body expansion of balloon catheter is a kind of expansion gear that can form cavity in fracture is subsided vertebral body, is made up of an expandable balloon-expandable 6, outer catheter 4, inner catheter 9, support seal wire 5 and Y type link 2, as shown in Figure 1.
As shown in Figure 2, this utility model is in balloon-expandable 6, two signs 8 can adopt saturating radioactive material to make and attached on the inner catheter 9, inner catheter 9 and the balloon-expandable 6 far-ends formation cecum that links together, support seal wire 5 is inserted in the inner catheter 9 total is played a supportive role, the horizontal tube structure 14 of inner catheter 9 and Y shape link 2 constitutes connected component, outer catheter 4 couples together with joint 15 places of Y type link 2, and constitute a closed channel with the side pipe 12 of inner conduit 9 and Y type link 2, balloon-expandable 6, as shown in Figure 3.
In use, adopt the method for pedicle to enter in the body.Handle 1 place of operator's hand-held supports seal wire 5 is tightened on the port one 0 of Y type link 2, port one 1 place that connects Y type link 2 with syringe one class air extractor, pulling air extractor piston is taken out air in balloon-expandable 6 and the outer catheter 4, make balloon-expandable 6 become tight pencil attitude, as shown in Figure 1, so that enter the working region by service aisle smoothly.When entering vertebral body inside, hand-held Y type link 13 places, send into service aisle gently, observe the degree that labelling 3 estimation conduits enter on the conduit, observe balloon-expandable 6 inside simultaneously and do not radiate the position of sign 8 thoroughly, guarantee two thoroughly radiation sign 8 stretch out service aisle fully, whole balloon-expandable 6 is in operative site scope inside.The pressure apparatus that port one 1 usefulness by Y type link 2 has graduation apparatus slowly pours contrast media in balloon-expandable 6, treat that balloon-expandable 6 is slowly expansion-molded, props up the compression vertebral body gradually.When waiting to reach ideal height, the reuse pressure apparatus inflating medium in the balloon-expandable 6 of finding time makes balloon-expandable 6 be in the state of tightening, and by the service aisle withdrawing device, after device is extracted out, has stayed the cavity of a shaping in vertebral body.
