It is provided with the syringe fixing piece for fixing syringe, control syringe fixing piece rotation is additionally provided on the third sliding item 302
Rotating mechanism；
It is provided on the sliding rail 4 for limiting the first sliding sliding of bar 101, second bar 201, third slides bar 301
4th position-limit mechanism.
Pass through above-mentioned technical proposal：Carrying out preoperative need by carrying out cerebral artery Doppler flow mapping inspection, i.e.,：Allen is tried
It tests, checks the blood supply of hand, the identical situation between radial artery and ulnar artery.1. patient with the hands presses radial artery simultaneously
And ulnar artery；
2. advising patient firmly to clench fist and spread one's fingers repeatedly 5~7 times to bleach to palm；
3. unclamping the compressing to ulnar artery, continues to keep compressing radial artery, observe palm color change.
If palm color < 10s redden rapidly or restore normal, i.e. Allen negatives；If on the contrary, 10s palm colors
Still it is pale, i.e. Allen experiments are positive.
Radial artery is to puncture target vessel on the right side of conventional selection.Point of puncture selects (processus styloideus radii in rasceta 2~4cm of proximal end
Inside) radial artery pulse most obviously locates, and 1% 1~2ml of lidocaine is in point of puncture local infiltration anesthesia.Outer tube needle
(Terumo) Seldinger methods puncture radial artery, see spray blood backed off after random puncture needle, the soft straight seal wire of head are placed in through outer tube, through leading
Silk merging 5F radial artery sheaths extract seal wire, and inject nitroglycerin 0.2mg, intravenous injection heparin 2500U by the side pipe of sheath
Carry out whole body test tube of hepari.Conventional 5F pigtails hand shaft row aorta bends radiography, selective angiography catheter using 5FSimmon I,
Simmon II conduits, are applied to loop technology, row bilateral carotid and left vertebral artery radiography, and right side vertebral artery can be according to feelings
Condition selects conduit, and vertebral artery is directly entered in subclavian artery, or conduit of pulling back after the arch of aorta is at loop carries out selectivity and makes
Shadow.Radiography finishes pulling out sheath, and 6h is oppressed with special radial artery hemostat.Position of radial artery superficial without special preserved skin and is shown
Reveal privacy places, and postoperative compression hemostasis is convenient, postoperative local hematoma, arteriovenous fistula, artery dissection incidence are less.
Radial artery is located on arm, still can be because of some god even if having sprayed anaesthetic when performing the operation to radial artery
Through reflection, the twitch that hand occurs in the course of surgery can be caused, and the equipment of the present invention, then hand can be limited by providing one kind
The equipment of arm twitch.
Wherein in the course of surgery, it will be manually placed at the position between two sliding rails 4, can presses machine by two later
Structure 1 is separately positioned on the both ends of sliding rail 4, and a contact mechanism 1 can limit palm, another contact mechanism 1 can then limit
Rear arm, and operative region is located at the position of two contact mechanisms 1.In the present invention, contact mechanism 1 is can be adjusted
, it can be slid on sliding rail 4 by the first sliding bar 101, adjust position, used to adapt to the different people of arm length,
Position can be limited by the 4th position-limit mechanism later.Simultaneously the first sliding is provided on the first sliding bar 101
Item 102, the first sliding item 102 is then that can carry out sliding up and down on the first sliding bar 101, to push down arm and palm, it
The first sliding bar 101 is limited by the first position-limit mechanism afterwards, plays fixed function, is thus adapted to different thick
The people of thin arm uses.
And be arranged leather hose fixed mechanism 2 be then for fixing used in leather hose, in step 2 and step 3 can use arrive
The part of outer tube, outer tube is inserted into artery, and it is all artificially to use to be moved through conference and cause arterial injury, the prior art
What hand was held, and can carry out realizing fixation by leather hose fixing piece in the application, while the second sliding bar 201 can be
4 enterprising line slip of sliding rail, when being slid onto suitable position, can by the 4th position-limit mechanism pair second slide bar 201 into
Row is fixed, and in height in phase, the second sliding item 202 is that sliding is connected on the second sliding bar 201, can be passed through later
Second position-limit mechanism is limited after the completion of adjusting, and in the horizontal direction, it can be by adjusting slipping block 203, to adjust.
It can be adjusted about syringe, sliding bar 301 by third can slide on sliding rail 4, adjust position,
It uses to adapt to the different people of arm length, later position can be limited by the 4th position-limit mechanism.Exist simultaneously
Third sliding item 302 is provided on third sliding bar 301, third sliding item 302 is then that can slide to carry out on bar 301 in third
Sliding up and down is limited by third position-limit mechanism to slide bar 301 to third later to adjust the position in short transverse
Fixed function is played in position, and syringe is fixed on syringe fixing piece, rotating mechanism is provided on syringe fixing piece, to adjust
On the one hand the angle of markingoff pin cylinder can play the fixation to syringe, and can be adjusted as needed in this way.
