Description
Technical field
The invention belongs to a kind of medical apparatus and instruments of fixedly diacan.
Background technology
Present clinical artery and vein puncture is " blind wearing " substantially, namely sees the vein blood vessel color or touches vein trend or arteriopalmus, sees blood back behind the inserting needle, further pin is all inserted fixing in the blood vessel or under the guiding of ferrum nook closing member the soft trocar is inserted blood vessel.Its shortcoming is: 1, what is called is seen or touched just a kind of sensory effect from appearance: when needle point contacted blood vessel, vein may be crushed or be out of shape; A kind of beating of filling the air that tremulous pulse may just be felt, the position of nook closing member contact skin may not be its center or so-called " off-centre "; 2, needle point prick skin and subcutaneous tissue but before not reaching blood vessel, can disturb the sensory effect's that puncture person has first judgement: the vein loop no longer resembles previous so clear or its trend or arteriopalmus no longer is position or the direction that had before determined; And puncture needle arrives which aspect between skin and the blood vessel for known to the puncture person; 3, see that the laggard stepping pin process of blood back may pass blood vessel and cause puncture failure by needle point again; Nook closing member is in blood vessel, but the soft tube of outside is also outside vascular wall, and this moment blindly or put by force pipe and it may be inserted EV soft tissue; 4, infant, obesity or edema patient, advanced tumor patient can't touch or see the blood vessel direction of travel, or too dark or blood vessel wall sclerosis, cause success rate greatly to descend.B ultrasonic is introduced medical domain allows new inferior professional health care personnel produce: the B ultrasonic medical worker.But they only can provide for the patient a kind of imaging data of atraumatic; And a simple puncture needs it to cooperate just and may finish with professional puncture personnel " magic horn ".
Summary of the invention
The object of the present invention is to provide a kind of locate clear and definite, puncture accurately, put in place, easy to operate B ultrasonic guiding artery and vein puncture holder.
The present invention solves the technical scheme that its technical problem takes: B ultrasonic guiding artery and vein puncture holder, it is characterized in that, and comprise following parts,

One controller, described controller are controlled described fan-shaped puncture plate and are rotated relative to fan, and fan-shaped puncture plate and fan are broken away from, and under the effect of back-moving spring, fan-shaped puncture plate is inwardly turned reset;
One puncture needle guiding draw-in groove, described puncture needle guide card channel process line direction is arranged on fan-shaped puncture plate outer surface, is used for puncture needle is installed, and makes puncture needle along guiding draw-in groove fore-and-aft direction slidably.
Be provided with friction plate in described fan-shaped puncture plate and the contact site of picking up the ears, because the effect of friction plate, fan-shaped puncture plate can be parked in the position of any needs during to external rotation at any time.
Described guide and limit mechanism comprises the gathering sill and the lead that is arranged on the fan that is arranged on fan-shaped puncture plate middle part, the described gathering sill angle of can in lead, sliding, and described spring is nested with on lead and two ends are fitted in fan-shaped puncture plate and fan surface, described spring is Compress Spring, picks up the ears also can rotate an angle around the fan circle so that described fan-shaped puncture plate is close to.
Described controller is the one handle that is extended out to the fan-shaped puncture plate outside by lead, can promote fan-shaped puncture plate when inwardly pushing away and move inward, and the friction plate in the fan-shaped puncture plate outside and fan disengaging are got final product.
Controller comprises that is fixedly mounted on the cylindrical shell of fan on picking up the ears, a control knob is installed in the endoporus of housing, the front end of control knob is with the unofficial biography wheel of an end face with tooth pushing, the inner of unofficial biography wheel is with the interior runner that matches with the unofficial biography wheel, the end face of interior runner is provided with the tooth pushing that matches with unofficial biography wheel tooth pushing, and interior runner outer end is resisted against on the fan-shaped puncture plate.Like this, can press control knob, make friction plate and the fan in the fan-shaped puncture plate outside be separated from certain distance, until fan-shaped puncture plate is behind return under the effect of back-moving spring, press again control knob, fan-shaped puncture plate is moved in that the effect of spring is lower outside, be returned to initial condition.
The invention has the beneficial effects as follows: its advantage is: real realize " What You See Is What You Get ": the tremulous pulse that puncture or vein diameter and trend are presented in the puncture person visual field fully, no longer by the sensation puncture, but finish whole process under the vision on the complete meaning.Expliciting the position, accurate puncture put in place, and accurately finish and change puncture needle over to blood vessel fully and do not appear again or the disposable Endovascular of inserting of soft tube, not hemorrhagely can not cause vasospasm by the secondary stimulus tremulous pulse yet, make a common B ultrasonic medical worker just can realize puncture working.Realize that a people finishes whole operation, do not need the people in two different majors fields to cooperate, and reusable.
