Refering to fig. 1 shown in -4, a kind of vena cave thrombus withdrawing device, including syringe 1, pipe sheath 2, positioning pipe 4 and traction
Steel wire 5,2 rear end of pipe sheath are hand-held part 21, and 21 top two sides of hand-held part are equipped with vacuum suction interface 23 and inflation/deflation connects
Mouth 22, vacuum suction interface side wall is fixed with pipe cap 231 by connecting rope, and pipe cap 231 can be plugged in vacuum suction interface 23
In, 2 front end of pipe sheath is socketed with air bag, is connected between inflation/deflation interface 22 and air bag 3 by gas tube 221, and positioning pipe 4 is from hand-held
It is inserted at portion's opening 21 and is stretched out from 2 front end of pipe sheath, traction steel wire 5 is inserted into positioning pipe, and the rear end of traction steel wire 5 is fixed with drawing
The front end of ring 6, traction steel wire 5 is helical form contraction section 51, and helical form contraction section 51 is accommodated in the lumen of positioning pipe 4, pipe sheath
2 thrombus that is fixedly arranged at the front end with cuts mesh sheet 24, and thrombus cutting mesh sheet 24 is in a circular table shape and thrombus cutting mesh sheet 24 is into pipe sheath 2
Portion gradually tapers up, and positioning pipe 4 is probeed into from the bottom opening of thrombus cutting mesh sheet 24 and stretched out from 2 front end of pipe sheath, the hand
The opening for holding portion 21 is plugged with sealing-plug 211, the through-hole of perforation is provided at 211 center of sealing-plug and the internal diameter of through-hole and positioning pipe
Outer diameter it is equal.
Therein, the traction steel wire 5 selects Ultimum Ti material to be made.
One concrete application of the device are as follows: cavography puncture is needled into point of puncture, then by the needle core of puncture needle
It extracts, be rapidly inserted into seal wire in the sheath of puncture needle and inject contrast agent, seal wire is inserted at vena cave thrombus, extraction is worn
Point of puncture is cut using incision of skin knife and is inserted into vena cave convenient for pipe sheath 2 from from point of puncture, pipe sheath 2 is held by pricker sheath
Continuous insertion is until close at thrombus, syringe 1 is accessed inflation/deflation interface 22 for 2 front end of pipe sheath and injecting gas keeps air bag 3 fixed
In vena cave blood vessel, then the helical form contraction section 51 for being inserted with traction steel wire 5 and traction steel wire is constrained in positioning pipe 4
Positioning pipe 4 is inserted into thrombus and passes through thrombus, and 4 front end of positioning pipe is cone cell, convenient for across thrombus；Traction steel wire 5, which is pushed forward, to be made
Helical form contraction section 51 stretches out positioning pipe 4, and traction steel wire 5 is made of Ultimum Ti material, the helical form of traction steel wire 5
Contraction section 51 restores helical form and is held in the distal end of thrombus, catches on pull ring 6 and rearward pulls, and thrombus is mobile with traction steel wire 5
To 2 front opening of pipe sheath, since pipe sheath 2 is fixedly arranged at the front end with thrombus cutting mesh sheet 24, thrombus grumeleuse is mobile to 2 rear end of pipe sheath
During, thrombus outer diameter under the lateral cutting force cutting of thrombus cutting mesh sheet 24 gradually becomes smaller, until it is cut by thrombus
Cut the bottom opening of mesh sheet 24 and completely into pipe sheath 2, anti-tampon is excessive to be cannot be introduced into pipe sheath 2；Traction steel wire 5 is being led
Syringe 1 is connect on vacuum suction interface 23 while drawing thrombus and the handle of syringe is pulled to distal end to be adjusted to
Negative pressure state, the thrombus little particle that the cutting of thrombus grumeleuse falls off are sucked out from pipe sheath 2 into syringe under vacuum suction；When
After entering 2 inside of pipe sheath after being cut and by the thrombus that thrombus cuts mesh sheet 24, drawing positioning pipe 4 makes the spiral shell of traction steel wire 5
It revolves shape contraction section 51 to shrink in positioning pipe 4, thrombus is taken off from traction steel wire 5 at this time, and the thrombus grumeleuse taken off is inhaled in negative pressure
It is absorbed under drawing in syringe 1, entire thrombus takes out in operation, thrombus noresidue and leakage, and thrombus taking-up is more thorough, prevents
The thrombus grumeleuse only omitted again results in the problem of hemadostewnosis, blocking.
