The mono type great vessel branch support pusher has the advantages of being simple in structure, convenient to use, safe and the like.
Description
Technical field
This utility model relates to a kind of compression and discharge the device of 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 have applied for the utility model patent (patent No.: ZL201020240888.3) on January 12nd, 2011.For this Integral great vessel branch stent, we have designed again the Integral great vessel branch stent pusher.
The utility model content
The purpose of this utility model is defective and the deficiency that exists 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, hoop system of branch, 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 medicated cap, be provided with a tubule chamber in the conical head, the front portion of described inner core tube is located in the cylinder of top medicated cap, and pegs graft in the tubule chamber in the front end of inner core tube and the described conical head; Hoop system of described branch 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 be connected with the terminal connecting ring of branch hoop, described standing valve is located on the 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 the handle, and described standing valve is arranged on handle outer, and the end of described inner core tube is fixed on the end of handle by draught excluder.
The utlity model has the advantages such as simple in structure, easy to use, safe.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The Integral great vessel branch stent pusher, comprise: interior core system, hoop system of branch, 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 medicated cap 3 backward, be provided with a tubule chamber 4 in the conical head 1, the front portion of inner core tube 2 is located in the cylinder of top medicated cap 3, and pegs graft in the tubule chamber in the front end of inner core tube 2 and the conical head 14; Hoop system of branch 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 be connected with connecting ring 9 that 5 ends bind round in branch, standing valve 8 is located on the 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 and handle 12 are fixedly connected with by screw thread.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 the handle 12, and standing valve 8 is arranged on the outside of handle 12.The end of inner core tube 2 is fixed on the end of handle 12 by draught excluder 13.
Using method
1. set up the path that support discharges;
2. the branch stent with compression 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 being dropped back fully discharges main body rack fully;
6. releasing bracket component: the standing valve of safety line end is opened, then branch is bound round system's tractive and go out the external support component that makes and discharge.
