Description
Technical field
The present invention relates to technical field of medical equipment, realize turning to the interventional therapy device with positioning fenestration and method by laser catheter particularly to a kind of.
Background technology
The treatment of dissection of aorta and thoracoabdominal aortic aneurysm has increasingly trended towards intracavity, the substantially full intracavitary therapy of the abdominal aortic aneurysm of simple Type B interlayer and kidney mo(u)ld bottom half; Selective part A type interlayer is also attempting carrying out the treatment of intracavity; The abdominal aortic aneurysm of aneurysm of thoracic aorta, thoracoabdominal aortic aneurysm and kidney week or kidney mo(u)ld top half also more and more uses the method for intracavity to treat along with the progress of branch stent, windowing stent and parallel bracket technology. Intracavitary therapy dissection of aorta and aortic aneurysm because of its Wicresoft, efficiently, perioperative deaths rate, medium-long term survival rate and complication rate are not inferior to even better than conventional open surgery, have been increasingly becoming the first-selected therapeutic modality of doctor and patient; But intracavitary therapy yet suffers from many problems, the long-term patency rate problem of the displacement at a specified future date of the generation of various internal hemorrhage due to trauma, support, branch and windowing stent and important collateral blood vessels capped after the generation of the corresponding organs that occurs or limb ischemia. Relative to branch and the windowing stent of personalized customization, original position (insitu) windowing technology is more efficient and economical. Windowing stent technology is low compared to the incidence rate of its I type internal hemorrhage due to trauma of parallel bracket technology, but orthotopic fenestration technical difficulty is relatively big, and technical bottleneck essentially consists in and lacks suitable window opening tool.
Current windowing technology mainly has two kinds: one to be that foley's tube fits through pricker; Two be laser fiber point type burn window after follow up again seal wire and balloon expandable. Foley's tube fits through pricker technology needs patient to pass through elongated and bending conduit firmly puncture, and technical difficulty is big, and success rate is not high; The point type of laser fiber burns owing to optical fiber visuality under x-ray fluoroscopy is poor, enter after in support penetrating overlay film frame wall, may enter too deep and penetrate offside blood vessel wall, and need to exit optical fiber after optical fiber penetrates, hole diameter owing to burning out is less, thus penetrates seal wire in small-bore also highly difficult.
Disclosed in prior art a kind of " there is the sacculus dilating catheter of novel header terminal design ", see that publication number is: CN201551713U, publication date is: the Chinese patent of 2010-08-18, this relates to the sacculus dilating catheter of a kind of percutaneous tranluminal coronary angioplasty (PTCA), particularly a kind of sacculus dilating catheter with novel header terminal design, main by sacculus, balloon center bar, seal wire is by chamber and taper head end composition, the track of seeking that described taper head end adopts taper tapered designs, application laser welding technology connects sacculus and taper head end cone mouth portion, make between sacculus and head end in smooth excessiveness, taper head end terebrantia through grinding process, bore is consistent with guide wire diameter, both tight connectings, special taper head end material has good compliance, it is made not to be deformed the imagination by vascular bending place, can continue to keep the tight connecting state with guide wire. this utility model has by outer through little, can pass through tiny blood vessel, and the head end of compliance and seal wire are closely identical, by knee, are substantially reducing " fish mouth " phenomenon, greatly reduces the advantage such as wound of operation process medium vessels. this utility model can not realize the foley's tube that can turn to.
Summary of the invention
One of the technical problem to be solved in the present invention, is in that to provide a kind of interventional therapy device being realized by laser catheter and turning to positioning fenestration, realizes turning to and positioning function with laser catheter, and realize windowing function; Combining of both laser catheter and foley's tube is windowed for being accurately positioned of overlay film frame artificial blood vessel.
One of problem of the present invention is achieved in that a kind of interventional therapy device being realized by laser catheter and turning to positioning fenestration, including a laser catheter and a foley's tube, described laser catheter and foley's tube are arranged parallel from head end to tail end, described foley's tube is with sacculus, the head end of described laser catheter is beyond the head end of described foley's tube, the tube wall of one end of described foley's tube and laser catheter one end is fixed, and fixing position be positioned at described foley's tube sacculus before; Described laser catheter head end tube wall is embedded with at least four laser fibers, and four laser fibers extend to the tail end of laser catheter.
Further, the head end of described foley's tube is plane, and the diameter of foley's tube is 4F��8F.
Further, the head end of described laser catheter is inclined-plane, and the diameter of laser catheter is 6F��10F.
Further, the mode that one end of described foley's tube is fixing with the tube wall of laser catheter one end is: rivet is fixed or coil is fixed.
Further, described laser fiber is 4��8.
Further, the external compression pump of the afterbody of described foley's tube.
Further, the external laser therapeutic apparatus of the afterbody of described laser fiber.
The two of the technical problem to be solved in the present invention, are in that to provide a kind of interventional therapy method being realized by laser catheter and turning to positioning fenestration, realize turning to and positioning function with foley's tube, realize windowing function with laser catheter; Combining of the two is windowed for being accurately positioned of overlay film frame artificial blood vessel.
The two of problem of the present invention are achieved in that a kind of interventional therapy method being realized by laser catheter and turning to positioning fenestration, and described method is:
Described interventional therapy device is inserted in an overlay film frame artificial blood vessel so that laser catheter and foley's tube are positioned at overlay film frame artificial blood vessel;
Under the instruction sacculus of a target blood guides, in the sacculus of described foley's tube, inject contrast agent by a compression pump,
Along with the expansion of sacculus, described foley's tube separates with laser catheter, and laser catheter is increasingly turned to instruction sacculus direction and note invests overlay film frame artificial blood vessel's inwall;
Starting laser therapeutic apparatus and burn overlay film frame artificial blood vessel's wall, burn after tube wall until laser, stretch into seal wire in laser catheter, seal wire can pass through overlay film frame artificial blood vessel's wall, arrives 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, it is to avoid use the operation that external force punctures.
2, follow up seal wire in the process that laser catheter burns simultaneously, it is to avoid seal wire is again introduced into the technical operation of small holes.
