The internal conic joint of the needle seat of the utility model is connected with the handle to form a whole. The utility model has the advantages of convenient manipulation of operation doctors in the process of atrial septum puncture operations, and convenient fabrication.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of novel atrial septal puncture pin.
Background technology
The atrial septal puncture pin is the crux parts that use in the atrial septal puncture art.The atrial septal puncture art is applied to clinical by Cope and Ross etc. the earliest in nineteen fifty-nine, mainly be to be directly acquainted with a left side as a diagnostic techniques to feel concerned about the hemodynamics of system and the anatomical structure that system is felt concerned about on a radiography demonstration left side at that time, this technology is improved by Brockenbrough and Millins etc. subsequently.Along with the development of the application of pulmonary artery float catheter and retrograde left cardic catheter art, as diagnostic method, the atrial septal puncture value of technology is descending.But along with the application of undergone percutaneous balloon mitral valvuloplasty and preceding tropism's aortic valve dilatation, the atrial septal puncture art is used widely once more as Therapeutic Method.Radio-frequency (RF) ablation left side accessory pathways, room, left room speed, the isolation of pulmonary vein sections and ring pulmonary vein linear ablation left side room treatment atrial fibrillation etc. make the atrial septal puncture art occupy more and more important position in electric physiology radio-frequency ablation procedure, have become a kind of important technical ability of the essential grasp of cardiac electrophysiology doctor.
Atrial septal puncture is at first delivered to superior vena cava and subclavian vein intersection through right femoral vein with long steel wire, fully expands the skin incision and the subcutaneous tissue of right femoral vein site of puncture, produces resistance when avoiding pushing long sheath.Deliver to superior vena cava along the long steel wire sheath pipe that will puncture, withdraw from long steel wire, resorption and with heparin saline flushing sheath pipe, again puncture needle is upwards pushed until needle point in convergent divergent channel apart from the most advanced and sophisticated 2-3cm of convergent divergent channel place, under the perspective of X ray postero-anterior position, carry out the location of point of puncture then, the jump to left down of the visible convergent divergent channel head end of X ray image is held the pin hand and can be fallen into sense when the sheath pipe retreats to the atrium and enters fossa ovalis.Then, right front oblique 45 degree perspectives are suitably rotated puncture needle and sheath pipe down, and puncture needle and sheath tube head end are stretched, at this moment, the convergent divergent channel head end is positioned at interatrial septum central authorities, and perpendicular to the interatrial septum, last left hand is held puncture sheath pipe tail end, the right hand is held the puncture needle handle, pushing sheath tube makes it closely to contact with the interatrial septum gently, slides when avoiding puncturing, and the right hand is held puncture needle, the about 2-3cm of inserting needle, the puncture interatrial septum.
Current the application of heart intervention treating is more and more extensive along with the develop rapidly that gets involved equipment and equipment, makes it the atrial septal puncture art and obtains using more widely, and atrial septal puncture has become an important skill getting involved the doctor.At present, domestic employed clinically atrial septal puncture pin is external company and produces, and is mainly Cordis company, Daig company.The formation of atrial septal puncture pin comprises three parts, the one, and far-end has the needle point of certain angle of bend, the 2nd, needle tubing, the 3rd, needle stand.Needle stand has female cone joint and side valve of 6% (Rule) tapering of a standard.Because of the atrial septal puncture pin needs through the femoral vein blood vessel to the right room of heart, therefore need possess good operating characteristics, comprise slickness, propelling movement or return removing property and rotary torsion that safety comprises the stretching resistance, needle tubing stiffness, needle tubing toughness of atrial septal puncture pin and to the mechanical stimulus of cardiac muscle etc.
Present general clinically atrial septal puncture pin, the needle point that a certain angle is arranged by the needle tubing and the needle tubing far-end of a medical stainless steel material, and the needle stand of being made by stainless steel material of needle tubing near-end forms, needle stand also has one one end and becomes pointed handle.We find in clinical practice, for guaranteeing the atrial septal puncture needle set enough propelling movements and moment of torsion are arranged, and require the atrial septal puncture needle set that enough rigidity and toughness are arranged; For accurately delivering to the fossa ovalis position, head end need give and curve definite shape.The needle stand of clinical used atrial septal puncture pin all has a side valve at present, as the atrial septal puncture of intracardiac interventional therapy, influences the operation of surgical doctor.
Summary of the invention
The purpose of this utility model provides a kind of atrial septal puncture pin, and the technical problem that solve is to make things convenient for the surgical doctor operation.
This utility model is by the following technical solutions: a kind of atrial septal puncture pin, have needle tubing, and the needle stand that the needle point that the needle tubing far-end connects, near-end connect, the female cone joint of described needle stand is bound up on the handle.
Handle of the present utility model and female cone joint are made an integral body, are linked together.
The tapering of this utility model female cone joint is 6%.
Needle tubing of the present utility model and needle point adopt the medical stainless steel material.
This utility model needle tubing adopts welding with connecting of needle point.
Needle stand of the present utility model adopts medical stainless steel material or medical macromolecular materials.
Medical stainless steel material of the present utility model is OCr18Ni9Ti, and medical macromolecular materials are polyurethane, polyethylene or nylon.
This utility model atrial septal puncture pin is pre-bent to and has arcual curved shape, and the bending of its curved shape is according to the shape of the anatomical structure of human heart.
Handle one end of the present utility model has the tip, the most advanced and sophisticated bending direction that points to the atrial septal puncture pin.
This utility model compared with prior art, the female cone joint of needle stand is bound up on the handle and is integral, surgical doctor more convenient operation in the atrial septal puncture art process, and make simple.
