Background technique
Intracorporal qi depression to blood stasis, that is, the thrombus of people will cause blockage of channel, and blood circulation is unsmooth, easily formation myocardial infarction, cerebral infarction
Plug etc., less serious case causes to have a pain in the back, painful swelling of joints, rigidity of the neck, the numbness of fingers, have a dizzy spell, is handicapped etc.；Severe one is often endangered
And life.Rescue also often falls hemiplegia etc. after coming.There are many method of traditional treatment hemostasis (thrombus), some using by
It rubs method, the method for some cupping glass, use also is deposited, roasting, boiling hot, the methods of patch, in recent years also some uses magnetic therapy, electricity
The methods for the treatment of, thrombus treating apparatus are treated, but curative effect is not satisfactory, cannot eradicate, only play the role of alleviation.
Chinese patent " micropin positioning negative pressure extracts thrombus system " (CN201710360003.X) discloses a kind of human body blood
The negative pressure extraction system of bolt, achieves preferable effect in wide clinical application.But when puncturing, there are the following problems:
The micropin of the system is to fix by allen wrench from two limit screws of needle holder side fastening.System, which is repeated as many times, to be used
Afterwards, since limit screw and allen wrench are all tiny, the two it is easy to appear stripped thread phenomenon, and allen wrench be easy by
To abrasion, so that stopping effect is bad, there is micropin retraction when puncturing when serious, situation that can not be dazzling.And this is
The micropin of system is using limit screw in side stop, and needle body tip portion will appear deflection, when use cannot be guaranteed vertically into
Enter patient's diseased region, patient's pain is caused to aggravate.
Summary of the invention
In order to overcome the deficiencies of the prior art, it can easily and fast, neatly be adjusted the purpose of the utility model is to provide a kind of
Micropin, to quickly carry out the thrombus negative pressure puncture device that thrombus punching punctures.
The technical solution of the utility model is as follows: a kind of screw thread holds pin type thrombus negative pressure puncture device, it is characterised in that: by
Gas nozzle nut, negative-pressure dense seal, negative pressure puncture tank, needle holder, locking nut and the flat rib needle composition of screw-type, the gas nozzle nut
Centre be provided with a first inner circle duct passed through convenient for negative pressure；One is provided among the needle holder is convenient for negative pressure to pass through
Second inner circle duct, two sides of the needle holder respectively set a negative pressure circulation oblique hole, and the negative pressure circulation oblique hole is connected to institute
State needle holder inner circle duct and the negative pressure puncture tank；The negative pressure puncture tank is fixed on the needle holder and the gas nozzle spiral shell
Between cap；The tail end of the needle holder is threadedly coupled with the gas nozzle nut, and front end passes through screw thread and locking nut fixed thread
The flat rib needle of formula；Negative-pressure dense seal is equipped between the negative pressure puncture tank and the gas nozzle nut；The gas nozzle, circular hole in first
Road, the second inner circle duct and the vacuum flow through-hole form negative pressure channel.
The needle point of the flat rib needle of screw-type is flat prismatic, and tail portion is equipped with outer with needle holder front end screw-internal thread fit
Screw thread.
The needle point upper end of the flat rib needle of screw-type extends to needle point using two acute angles, and described two acute angles are in needle point
Triangular form, and the acute angle and the needle point are provided with cutting edge.
The utility model can be substantially increased in operation with the height of the flat rib needle of stepless changing, simple and convenient, firm stable
The speed of needle and adjustment is filled, inserting needle guarantees perpendicular angle, so that the hand-manipulating of needle is stablized, it can substantially reduced Principle of Pain；And device
Each component is to be threadedly coupled, and dismounting is simple and convenient, convenient for cleaning and disinfection.
