Description
Technical field
The present invention relates to technical field of medical equipment, in particular to a kind of laser balloon catheter of turning to and using method thereof.
Background technology
The treatment of dissection of aorta and thoracoabdominal aortic aneurysm has more and more trended towards chamber internalization, the abdominal aortic aneurysm of type full intracavitary therapy substantially under simple Type B interlayer and kidney; Optionally part A type interlayer is also attempting the treatment carrying out chamber internalization; Method treatment in the use chamber that on thoracic aorta knurl, thoracoabdominal aortic aneurysm and kidney week or kidney, the abdominal aortic aneurysm of type also gets more and more along with the progress of branch's support, window support and parallel bracket technology. Intracavitary therapy dissection of aorta and aortic aneurysm are because of its Wicresoft, efficient, and perioperative deaths rate, medium-long term survival rate and complication rate are not inferior to and are even better than tradition open surgery, have become the first-selected therapeutic modality of doctor and patient gradually; But still there is many problems in intracavitary therapy, the long-term patency rate problem of the displacement in the generation of various interior leakage, support long term, branch and support of windowing and important collateral blood vessels capped after the generation of the corresponding organs that occurs or limb ischemia. Relative to branch and the support of windowing of personalized customization, original position (insitu) windowing technology is more efficient and economical. Support technology of windowing is low compared to the incidence of leakage in its I type of parallel bracket technology, but orthotopic fenestration technical difficulty is relatively big, and technical bottleneck is mainly to lack suitable instrument of windowing.
It is that foley's tube coordinates puncture needle that current windowing technology mainly contains two kinds: one; Two be laser fiber optic point formula burn window after again follow-up lead silk and balloon expandable. Foley's tube coordinates puncture needle technology to need patient by the firmly puncture of elongated and bending conduit, and technical difficulty is big, and success ratio is not high; The point formula of laser optical fiber is burnt owing to optical fiber visuality under x-ray fluoroscopy is poor, enter after in support penetrating overlay film frame wall, may enter too dark and penetrate offside vessel wall, and need to exit optical fiber after optical fiber penetrates, hole diameter owing to burning out is less, thus wears into leading silk also very difficult in small-bore.
Prior art discloses " a kind of foley's tube " and sees that publication number is: CN102294071A, publication date is: the Chinese patent of 2011-12-28, this foley's tube is in the foley's tube of wire and foley's tube integration, produce step between can preventing the coil part of wire and the leading section of foley's tube from dividing, and improve the property passed through of foley's tube. Foley's tube (1) comprises the transition part (54) being made up of resin, and this transition part (54) smoothly connects the profile of the leading section of axle (51) in the profile of the outer coil (91) of front end coil portion (90) and front. This invention can not realize the foley's tube that can turn to, and leads the wearing into still having difficulties of silk.
Summary of the invention
One of the technical problem to be solved in the present invention, is to provide a kind of laser balloon catheter turned to, and realizes turning to and locating function with laser conduit, and realizes windowing function; Both laser conduit and foley's tube combine the accurate positioning fenestration for overlay film frame artificial blood vessel.
One of problem of the present invention is achieved in that a kind of laser balloon catheter turned to, and comprises a laser conduit and a foley's tube, and described foley's tube is divided into two parts; The foley's tube of first part with sacculus, the tail end of the described tail end of laser conduit and the foley's tube of first part all head end with the foley's tube of second section be connected mutually; The head end of described laser conduit exceeds the head end of the foley's tube of first part, and the foley's tube of described first part and the tube wall of laser conduit are fixed; Described laser conduit head end tube wall is embedded with at least four laser optical fiber, and four laser optical fiber extends to the tail end of foley's tube of described second section.
Further, the head end of the foley's tube of described first part is plane, and the diameter of the foley's tube of first part is 4F��8F.
Further, the head end of described laser conduit is inclined-plane, and the diameter of laser conduit is 6F��10F.
Further, the mode that the foley's tube of described first part and the tube wall of laser conduit are fixed is: rivet is fixed or coil is fixed.
Further, described laser optical fiber is 4��8.
Further, the external pressure pump of the afterbody of the foley's tube of described second section.
Further, the external laser therapy instrument of the afterbody of described laser optical fiber.
The two of the technical problem to be solved in the present invention, are to provide a kind of laser balloon catheter using method turned to, and realize turning to and locating function with foley's tube, realize windowing function with laser conduit; The two combine the accurate positioning fenestration for overlay film frame artificial blood vessel.
The two of problem of the present invention are achieved in that a kind of laser balloon catheter using method turned to, and the laser balloon catheter that can turn to inserts in an overlay film frame artificial blood vessel so that laser conduit and foley's tube are positioned at overlay film frame artificial blood vessel;
Under the instruction sacculus of a target blood guides, inject contrast medium to turning in the sacculus of laser balloon catheter by a pressure pump,
Along with the expansion of sacculus, the foley's tube of first part is separated with laser conduit, and laser conduit turns to instruction sacculus direction gradually and note is attached in overlay film frame artificial blood vessel's inwall;
Start laser therapy instrument and burn overlay film frame artificial blood vessel's wall, burn after tube wall until laser, stretch in laser conduit and lead silk, lead silk and can pass through overlay film frame artificial blood vessel's wall, arrive target blood.
It is an advantage of the current invention that: 1, by the cooperation of laser pipeline and balloon conduit so that laser directly burns overlay film frame blood vessel, avoid the operation using external force puncture.
2, in the process burnt at laser conduit, silk is led in follow-up simultaneously, avoids leading the technological operation that silk enters small holes again.
3, laser conduit burns out bigger hole, more auxiliary balloon expandable can obtain bigger caliber, is suitable for implanting larger sized stented vessel.
4, the application of conduit of the present invention can obviously reduce the technical difficulty of orthotopic fenestration, it is to increase technique successful rate, shortens patient and patient's X light open-assembly time simultaneously, protects the healthy of patient and patient.
