Description

A kind of multi-functional microtubular with supporting seal wire

Art

This utility model relates to a kind of with support seal wire, can be used for changing the sensing of PTCA seal wire or the multi-functional microtubular class medical apparatus and instruments for sending into second PTCA seal wire fast.

Background technology

Along with socioeconomic development, coronary heart disease has become one of most important disease of threat human health.Therefore percutaneous coronary intervention operation is also extensively carried out in worldwide, and the U.S. completes more than 1,000,000 examples every year, and the amount for surgical of China is also more than 400,000 examples.Along with the growth of amount for surgical, the Percutaneous Coronary Intervention of various complexity also increases gradually, wherein the process of branch vessel is difficult point wherein, especially the anatomical structure of element branches blood vessel special (as angulation, lacking effectively support, branch openings obvious stenosis etc.), PTCA seal wire is difficult to enter branch, cause operating time to extend, dose radiation and contrast medium use amount obviously increase, and success rate of operation reduces.Single chamber microtubular common at present cannot realize end on orientation direction-pointing function, enters branch do not act on guide PTCA seal wire.In addition; in Percutaneous Coronary Intervention, often there will be the situation needing feeding second PTCA seal wire to position, original PTCA seal wire place, when blood vessel is tortuous or pathological changes is serious; the feeding of second PTCA seal wire will become abnormal difficult, even cause the severe complications such as arteria coronaria perforation or interlayer.If had, a kind of device can fast and safely second PTCA seal wire is sent into original position will significantly improve procedure efficiency, reduce complication.

Summary of the invention

In order to improve the handling of PTCA seal wire, improve the ability that PTCA seal wire enters branch vessel, this utility model provides a kind of multi-functional microtubular with supporting seal wire, for blood vessel intervention operation.This microtubular, by inserting the support seal wire of moulding mistake to realize the directed direction-pointing function of microtubular head end in support chamber, helps the PTCA seal wire sent in guidewire lumen to arrive the branch vessel thought.Support chamber also can send into PTCA seal wire simultaneously, easily second seal wire can be delivered to the arteria coronaria position at original PTCA seal wire place.

This utility model solves the technical scheme that its technical problem adopts: this device forms by with the microtubular of support chamber and guidewire lumen and the support seal wire two parts with moulding ability.In microtubular body, segment outer radius is 1 to 1.2 millimeter, and support chamber is present in the whole process of microtubular, and the design of guidewire lumen can exist only in the scope of body inner segment near end points 30 centimetres.The most advanced and sophisticated 5 millimeters of softnesses of microtubular body inner segment, can be shaped as the shape supporting wire tips after sending into support seal wire.The support chamber of microtubular and guidewire lumen minimum diameter are 0.36 millimeter, can hold the standard P TCA seal wire that diameter is not more than 0.36 millimeter.The external end of microtubular is standard 6% Rule circular cone interface of funnel type, can conveniently send into support seal wire, and connects with the common medical syringe of standard 6% Rule cone joint or medical screw syringe.Support inner 1 centimetre of wire guides to make for having certain toughness and plastic material, remainder is the propelling movement seal wire that toughness is high, supporting wire guides outer end is a small-sized swing handle, for operating the rotation of seal wire and pushing action, and the interface portion of swing handle and seal wire is designed to standard 6% Rule cone joint pattern, can insert in the external female Luer of microtubular, prevent from supporting seal wire accidental movement or rotation.The diameter supporting seal wire is not more than 0.36 millimeter, and after inserting completely, length is equal with support chamber, ensures that support seal wire head end can not exceed support chamber and cause blood vessel injury.

The beneficial effects of the utility model are, microtubular head end can be carried out certain moulding with supporting the microtubular of seal wire, certain sensing is formed at Ink vessel transfusing, make up the moulding problem that simultaneously cannot meet multiple demand of PTCA seal wire head end, coordinate the moulding of PTCA seal wire itself, the ability that PTCA seal wire head end enters the complex lesions such as wide-angle bifurcated vessels can be improved.The full Konstantin Grcic that microtubular support chamber is right simultaneously had both facilitated the flushing of tube chamber, can insert again conveying or function of exchange that PTCA seal wire realizes PTCA seal wire.The PTCA wire guides outer end that microtubular can be enclosed within intravasation by design that guidewire lumen is only positioned at body inner end portion is fast delivered to Ink vessel transfusing, also can retains PTCA seal wire easily when withdrawing from microtubular, reducing the complexity of operation.This device is simple to operate, can improve PTCA seal wire manipulation ability.

Detailed description of the invention

Microtubular is made up of high molecular synthetic material, overall length 130 to 150 centimetres, and the microtubular substrate of different section has different characteristics.The moulding segment length of microtubular 5 millimeters, character is soft, and the moulding seal wire that can well be inserted into wherein is moulding.The transition section length of microtubular 30 centimetres, has certain hardness, avoids being supported seal wire excessive distortion, but flexible relative, can smoothly by the knee of guiding catheter and arteria coronaria.The supporting section length 100 to 120 centimetres of microtubular, has higher hardness, can avoid distortion, the support force providing microtubular to operate and torsion.The diameter 1 to 1.2 millimeter of moulding section of microtubular and changeover portion, better to pass through stenotic lesion, and the diameter of hold segment can equal or slightly be coarser than changeover portion.

The internal diameter identical with conventional PTCA seal wire diameter (as 0.36 millimeter) of guidewire lumen, guidewire lumen is distributed in moulding section and changeover portion of microtubular, total length 20 to 30 centimetres.The Way out that guidewire lumen is positioned at moulding section can be parallel to the axis of microtubular, or is designed to axis at a certain angle.The Way out that guidewire lumen is positioned at changeover portion is then in a certain angle with the axis of microtubular.During use, guidewire lumen can be enclosed within the PTCA seal wire tail end that enters arteria coronaria easily and follow seal wire and be delivered in arteria coronaria by microtubular.Also can retain PTCA seal wire easily and exit microtubular after PTCA seal wire puts in place.

Support chamber is distributed in the whole process of microtubular, and internal diameter is 0.36 millimeter.The external end of support chamber is funnel type construction standard 6% Rule circular cone interface, can mate with existing standard syringe and screw syringe, and convenient support seal wire or PTCA seal wire insert simultaneously.

Support seal wire to be made up of alloy, homogenizing seal wire or composite construction (as metal inside adds winding arrangement or other structures) can be adopted to reach suitable physical characteristic.Support seal wire and be divided into moulding section, hold segment and swing handle.Moulding section is 0.36 millimeter with hold segment diameter.Moulding section of toughness is comparatively strong, and can keep certain form after moulding, moulding section can be moulding or moulding voluntarily by patient in art in advance in advance.Hold segment has certain degree of hardness, supports propelling movement needed for seal wire or spinning force to provide operation.Support seal wire outer body and have little swing handle, facilitate patient to control to support seal wire.Swing handle and hold segment connecting portion shape load criterion 6% Rule cone joint shape, can insert the interior clamping of interface of the external end of microtubular.Correct in support wire guides after clamping that to support cavity the inner with microtubular concordant, support chamber can not be exceeded and cause blood vessel injury.
