The pusher for the integral great vessel branch stent comprises an inner core system, a branch hoop system and a handle system, and is characterized in that the inner core system comprises a conical head and an inner core tube; a cylindrical hood backwards extends on the rear end face of the conical head; a slim tube cavity is arranged in the conical head; the front part of the inner core tube penetrates into the cylinder of the hood; the front end of the inner core tube is connected to the slim tube cavity in the conical head in a inserting manner; the branch hoop system comprises a branch hoop, a bypass wire, a safety wire and a standing valve, wherein the branch hoop is made of dacron; the bypass wire and the safety wire are respectively made of a nylon wire; the tail end of the branch hoop is fixedly provided with a connecting ring; the bypass wire is connected with the connecting ring fixedly arranged at the tail end of the branch hoop; the safety wire passes through the branch hoop, and is connected with the connecting ring at the tail end of the branch hoop; the standing valve is arranged on the safety wire in a penetrating manner; and the handle system comprises a sheath, an inner rod, a handle and a sealed valve. The pusher for the integral great vessel branch stent disclosed by the invention has the advantages that the structure is simple, the use is convenient and safe, and the like.
Description
Technical field
The present invention relates to a kind of compression and reach the device that discharges Integral great vessel branch stent in human body.
Background technology
At present, be used for the treatment of dissection of aorta or aneurysmal trunk overlay film frame is the straight tube support mostly.When dissection of aorta or aneurysm were involved the branch vessel of aortic arch, the straight tube support can not be used for the treatment of because it can not keep the branch vessel of aortic arch.For the dissection of aorta of involving aortic arch or aneurysm, we have designed Integral great vessel branch stent, and on January 12nd, 2011, have applied for the patent of invention (patent No.: ZL201020240888.3).For this Integral great vessel branch stent, we have designed again the Integral great vessel branch stent pusher.
Summary of the invention
The objective of the invention is the defect and the deficiency that exist for solving above-mentioned prior art, and a kind of Integral great vessel branch stent pusher is provided.
The technical scheme that adopts is:
The Integral great vessel branch stent pusher, comprise: interior core system, branch's hoop system, handle system, described interior core system comprises conical head and inner core tube, the rear end of described conical head has extended a cylindric aft-opening top cap, be provided with a tubule chamber in conical head, the front portion of described inner core tube is located in the cylinder of top cap, and pegs graft in the tubule chamber in the front end of inner core tube and described conical head; Described branch hoop system comprises: branch's hoop, the thread bridge line of nylon and safety line and the standing valve made by terylene, the end of described branch hoop is fixed with a connecting ring, described bridge line binds round end fixed connecting ring with branch and is connected, described safety line passes branch's hoop, and with the connecting ring of branch hoop end, be connected, described standing valve is located on described safety line; Described handle system comprises: epitheca, and interior bar, handle, draught excluder, described epitheca is nested with the outside at interior bar, and interior bar is fixedly connected with by screw thread with described handle.All there is a tube chamber inside of interior bar and handle, and the tube chamber of interior bar communicates with the tube chamber of handle; Handle inside has an oblique lumens that is connected with handle outer.Described safety line is passed the oblique lumens in handle, and described standing valve is arranged on handle outer, and the end of described inner core tube is passed draught excluder and is fixed on the end of handle.
The present invention has the advantages such as simple in structure, easy to use, safe.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The Integral great vessel branch stent pusher, comprise: interior core system, branch's hoop system, handle system, described interior core system comprises conical head 1 and inner core tube 2, the rear end face of conical head 1 has extended a top cylindraceous cap 3 backward, be provided with a tubule chamber 4 in conical head 1, the front portion of inner core tube 2 is located in the cylinder of top cap 3, and pegs graft in the tubule chamber in the front end of inner core tube 2 and conical head 14; Branch's hoop system comprises: branch's hoop 5, the thread bridge line 6 of nylon and safety line 7 and the standing valve 8 made by terylene, the end of branch's hoop 5 is fixed with a connecting ring 9, bridge line 6 binds round 5 end fixed connecting rings 9 with branch and is connected, safety line 7 passes branch's hoop 5, and with the connecting ring 9 of branch hoop 5 ends, be connected, standing valve 8 is located on safety line 7; Handle system comprises: epitheca 10, and interior bar 11, handle 12, draught excluder 13, epitheca 10 are nested with in the outside of interior bar 11, and interior bar 11 is fixedly connected with by screw thread with handle 12.The inside of interior bar 11 and handle 12 is respectively equipped with tube chamber 14,15, and the tube chamber 14 of interior bar 11 communicates with the tube chamber 15 of handle 12; Handle 12 inside have an oblique lumens 16 that links with handle 12 outsides.Safety line 7 is passed the oblique lumens 16 in handle 12, and standing valve 8 is arranged on the outside of handle 12.The end of inner core tube 2 is passed draught excluder 13 and is fixed on the end of handle 12.
Using method
1. set up the path that support discharges;
2. the branch stent that will compress pushes to aortic arch along adding stiff guide wire;
3. epitheca is partly dropped back, make the component of compression expose epitheca, the traction bridge line makes the component traction to bending top set's intra-arterial;
4. interior core system is pushed to front release bare bracket part;
5. epitheca is dropped back fully main body rack is discharged fully;
6. releasing bracket component: the standing valve of safety line end is opened, then branch is bound round the system tractive and go out the external support component that makes and discharge.
