Working principle of the present invention:
Referring to Figure of description 1-7, by the way that blood vessel nest mechanism 2 is arranged, in use, pushing top plate 5, top plate 5 drives solid
Inner tube 3 is determined in limitation 26 internal slide of cylinder, to limit motion track of the fixed inner tube 3 inside outer tube 1, is pushed up simultaneously
Plate 5 moves inside impenetrating mouth 7, drives positioning ring 6 in 8 internal slide of locating slot while top plate 5 is mobile, thus in fixation
The motion track of pipe 3 carries out further limit and reinforces, while being defined to the moving distance of fixed inner tube 3, later will be small
It is inserted into internal blood vessel in the fixation inner tube 3 of blood vessel diameter, then presses pressing plate 13, pressing plate 13 is pushed to the first spring 14
It is squeezed, while pressing plate 13 compresses the second air bag 11, it will be interior by conveying tracheae 10 after the compression of the second air bag 11
The gas in portion is delivered to inside the first air bag 9, and cross-sectional shape connects after being set as the first air bag 9 expansion of annular with vascular wall
Touching pushes pressing plate 13 so that fixed inner tube 3 be fixed in the blood vessels backward later, and pressing plate 13 is driven solid by top plate 5
Inner tube 3 is determined to bouncing back inside outer tube 1, and extend spirally pipe 4 facilitates moving horizontally for fixed inner tube 3, can be quickly by blood vessel
It is nested in fixed inner tube 3, effective solution blood vessel is narrow to be difficult to nested problem, reduces the difficulty of blood vessel nesting, reduces nested
Time, to promote the speed of vascular anastomosis；
Referring to Figure of description 2 and attached drawing 3,21 one end of returning face plate is pressed by the way that fixed mechanism 16 is arranged when fixed, it is horizontal
Cross sectional shape is set as the returning face plate 21 of V-arrangement and is overturn by 22 Duis of shaft, when returning face plate 21 is overturn to second spring 24 into
Row squeeze, 21 one end of returning face plate reduce the other end then drive traveller 19 be lifted, traveller 19 in 20 internal slide of the first slide cartridge, thus
The lifting track of traveller 19 is defined, while traveller 19 drives auxiliary made of pvc material by pressure ring 18 into outer tube 1
Wall is close, when the positioning ring groove 15 on fixed 3 surface of inner tube is moved to 17 top of fixed ring, unclamps returning face plate 21, second spring
24 push 21 one end of returning face plate to be promoted, and 21 other end of returning face plate drives traveller 19 that auxiliary is pushed to decline by pressure ring 18, assist simultaneously
The fixed ring 17 made of rubber material is driven to snap onto inside positioning ring groove 15 by pressure ring 18, so that blood vessel is fixed,
It can be convenient and efficiently carry out comprehensive fixation to blood vessel, improve fixed speed, improve fixed efficiency.
