Detailed description of the invention
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with in the embodiment of the present invention
Accompanying drawing, is clearly and completely described the technical scheme in the embodiment of the present invention, it is clear that described embodiment is only
The embodiment of a present invention part rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, all should belong to the model of present invention protection
Enclose.
Guide gip filter according to embodiments of the present invention, as depicted in figs. 1 and 2, including: catheter 1 and trocar sheath 2；Wherein,
Trocar sheath 2 includes: first sleeve 21 and the second sleeve pipe 22, flexible by many between first sleeve 21 and the second sleeve pipe 22
Filtering rod 23 connects, and first sleeve 21 fixed cover is located on catheter 1, and the second sleeve pipe 22 is set on catheter 1 slidably,
Second sleeve pipe 22 slides into the first predeterminated position towards first sleeve 21 and many filtering rods 23 can be promoted curved, the second sleeve pipe
22 slide into the second predeterminated position away from first sleeve 21 can pull many filtering rods 23 linear.
Guide gip filter according to embodiments of the present invention, sheathed trocar sheath 2 on catheter 1, trocar sheath 2 includes: first set
Pipe 21 and the second sleeve pipe 22, connected by many flexible filtering rods 23 between first sleeve 21 and the second sleeve pipe 22, first
Sleeve pipe 21 fixed cover is located on catheter 1, and the second sleeve pipe 22 is set on catheter 1 slidably, in thrombolytic operation process,
Second sleeve pipe 22 is slided towards first sleeve 21 many filtering rods 23 can be strutted the arc making it in bending, be dissolved
Thrombosis can be stopped by many filtering rods 23, anti-tampon refluxes, and solves in prior art at thrombolytic operation process
In the thrombosis that is dissolved be susceptible to the backflow impact technical problem that is normally carried out of operation.
When being embodied as, filtering rod 23 is elastic filtering rod, and after operation, filtering rod 23 can be certainly under the effect of elastic force
Dynamic reinstatement such that it is able to make guide gip filter extract out from human vas.
Owing to thrombolytic process time is longer, after promoting the second sleeve pipe 22 to be strutted by many filtering rods 23, need to overcome filtration
The elastic force of bar 23 is fixed, in order to use for a long time, therefore, as in figure 2 it is shown, be also arranged with stopping means on catheter 1
3, stopping means 3 is positioned at the rear end of the second sleeve pipe 22, stopping means 3 include multiple can extending radially out or returning along catheter 1
Movable buckle 31, alternatively, movable buckle 31 is provided with three, when many filtering rods 23 are strutted necessarily by the second sleeve pipe 22
During degree, the concrete size that struts determines according to the blood vessel thickness of human body.
What filtering rod 23 was different struts the different fixed positions of corresponding second sleeve pipe 22 of size, arranges three movable buckles 31
Second sleeve pipe 22 can be limited to three different positions, so that filtering rod 23 has three kinds different to strut diameter.According to
Needing to be pushed to the second sleeve pipe 22 corresponding position, the second sleeve pipe 22 can be limited by corresponding movable buckle 31, made
Filter bar 23 can keep softened state, it is simple to the carrying out of operation.
In order to make catheter 1 to be sprayed to equably in thrombosis by thrombolytic solution, in the front end of catheter 1, there is drain
Hole 11, delivery hole 11 is arranged on the front end of catheter 1, thus thrombolytic solution is had certain impulse force and is sprayed to blood in thrombosis
Bolt dissolves.
Time specifically used, catheter 1 is stretched in blood vessel, and make delivery hole 11 be positioned in thrombosis, as in figure 2 it is shown, subsequently
Promoting forward the second sleeve pipe 22 to be propped up by filtering rod 23, many filtering rods 23 after propping up are in bird-caging, it is possible to blood vessel
Fit, as in figure 2 it is shown, make filtering rod 23 keep strutting shape by the stopping means 3 of rear end by fixing for the second sleeve pipe 22 subsequently
State, thrombolytic solution is injected by catheter 1 rear end, and the thrombolytic solution of injection is sprayed thromboembolism, the blood of dissolving by delivery hole 11
Bolt can posteriorly flow, and many softened filtering rods 23 filter and intercept, and anti-tampon posteriorly refluxes.
Below it is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come
Saying, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as
Protection scope of the present invention.
