Detailed description of the invention
See Fig. 1, a kind of CTO reverse seal wire technology assist reverse seal wire enter the device of forward guiding catheter, including pushing connecting rod 1, the tail end of described propelling movement connecting rod 1 is provided with the handle 2 of propelling movement, it is characterized in that: the head end of described propelling movement connecting rod 1 is provided with disk-like structure 3, the termination 4 of described propelling movement connecting rod 1 is buried in this disk-like structure 3；Described disk-like structure 3 is provided with two holes for connecting two lacunas respectively, respectively orbit hole 8 and working hole 9, and said two lacuna proximal openings is in pushing connecting rod 1 side；Said two lacuna includes the rail cavity 5 that forward pushes and the work lacuna 6 assisting reverse seal wire entrance forward guiding catheter；Described disk-like structure 3, rail cavity 5 constitute the working region 7 of this device with work lacuna 6.
This device uses following size optimal: total length is 140, working region 7 overall length 30 mm；Disk-like structure 3 a diameter of 5.00；Disk-like structure 3 degree of depth is 2.00mm；Pushing connecting rod 1 external diameter is 1.00；Working chamber and rail cavity internal diameter are respectively 0.02mm；Handle 2 length 15.00, external diameter are 10.00.
Seeing Fig. 2, orbit hole 8 is positioned at the centre of disk-like structure；Described working hole 9 is adjacent with orbit hole 8.This meets the requirement of human heart operation.
Disk-like structure 3 is made for medical silica-gel, and it is bonded together with pushing connecting rod 1.
Handle 2 is made up of medical plastic, and it is bonded together with pushing connecting rod 1.
Push connecting rod 1 to be made up of medical stainless steel material.
Structure and using method explanation:
1) this device pushes connecting rod 1 is medical stainless steel material.
2) handle 2 of tail end, makes for medical plastic, uses High-strength glue bonding.
3) medical silica-gel that the disk-like structure 3 of head end is soft is made, and when delivering to guiding catheter far-end, opens in umbrella, uses High-strength glue to bond with pushing connecting rod 1.
4), in operation process, after reverse seal wire is by CTO pathological changes obturation section, this auxiliary device is used.
5) because of the medical silica-gel material that disk-like structure 3 is softness, therefore it is collapsible, thus along forward seal wire (forward seal wire penetrates rail cavity), by guiding catheter, arrives guiding catheter far-end.
6) disk-like structure 3 of head end, after arriving guiding catheter far-end, without the restriction of guiding catheter, the disk-like structure 3 of head end struts automatically in umbrella.
7) disk-like structure 3 has two holes, connects two lacunas, and it is other (working area silica gel structure proximal segment) that lacuna proximal segment is opened on propelling movement connecting rod 1.One is the rail cavity that the i.e. forward of rail cavity 5 pushes；One is work lacuna 6, for assisting reverse seal wire to enter the lacuna of forward guiding catheter.
8) head end disk-like structure 3 had once added guiding catheter head end area, therefore reverse seal wire easily enters the work lacuna 6 in auxiliary device working area.
9) when reverse seal wire enters the work lacuna 6 of auxiliary device, and entering after forward guiding catheter along this lacuna, withdraw from auxiliary device, reverse seal wire is then stayed in forward guiding catheter, thus continues following steps of performing the operation.
