Detailed description of the invention
See Fig. 1, a kind of auxiliary reverse seal wire enters the device of forward guiding catheter, comprise and push 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, is respectively orbit hole 8 and working hole 9, and described two lacuna proximal openings are in propelling movement connecting rod 1 side; Described two lacunas comprise the rail cavity 5 that forward pushes and the work lacuna 6 of assisting reverse seal wire to enter forward guiding catheter; Described disk-like structure 3, rail cavity 5 form the working region 7 of this device with work lacuna 6.
This device adopts following size best: total length is 140 ㎝, working region 7 overall length 30 mm; Disk-like structure 3 diameter is 5.00 ㎜; Disk-like structure 3 degree of depth is 2.00mm; Pushing connecting rod 1 external diameter is 1.00 ㎜; Work lacuna 6 and rail cavity 5 internal diameter are respectively 0.02mm; Handle 2 length 15.00 ㎜, external diameter are 10.00 ㎜.
See 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, its with push connecting rod 1 and be bonded together.
Handle 2 is made up of medical plastic, and it is bonded together with propelling movement connecting rod 1.
Push connecting rod 1 to be made up of medical stainless steel material.
Structure and using method illustrate:
1) this device pushes connecting rod 1 is medical stainless steel material.
2) handle 2 of tail end, for medical plastic is made, uses High-strength glue bonding.
3) disk-like structure 3 of head end is that soft medical silica-gel is made, and when delivering to guiding catheter far-end, opens in umbrella, uses High-strength glue to bond with propelling movement connecting rod 1.
4), in operation process, after reverse seal wire is by the inaccessible section of CTO pathological changes, this auxiliary device is used.
5) because of the medical silica-gel material that disk-like structure 3 is soft, 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 the nearly section of lacuna is opened on and pushes connecting rod 1 other (the nearly section of working area silica gel structure).One rail cavity pushed for rail cavity 5 i.e. forward; One is work lacuna 6, for auxiliary reverse seal wire enters 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 is easy to the work lacuna 6 that enters in auxiliary device working area.
9) when reverse seal wire enters the work lacuna 6 of auxiliary device, and after entering forward guiding catheter along this lacuna, withdraw from auxiliary device, reverse seal wire is then stayed in forward guiding catheter, thus continues operation following steps.
