Description

A kind of device for the clinical medical protective cradle conveying of coronary heart disease

Technical field

The utility model relates to field of medical technology, more particularly to one kind are defeated for the clinical medical protective cradle of coronary heart disease The device sent.

Background technique

With the breaking-out of interventional technique, the raising of Doctors' skill level is intervened, is clinically frequently encountered some complicated diseases Become, such as left main bifurcation lesions, distortion lesion, Long lesion, calcification lesion, Chronic total occlusion.Wherein for calcium Change distortion lesion and some blood vessel proximal segments placed bracket need by brace sections in distally again be implanted into bracket case, Its bracket makes bracket be undermined de- load sometimes by being usually present difficulty.Interventional therapy mistake is increased to a certain extent The risk lost.

At present these brackets are difficult to by and are made with the easily damaged lesion of bracket, common technology has sufficient sacculus pre-expansion , the application of Cutting balloon is the application of turnery technology and double seal wire technologies, sacculus anchoring techniques, primary and secondary microcatheter technology, double The application of microcatheter technology and Guidzilla conduit.But still there are some problems, such as seal wire winding, anchoring injury of blood vessel, coronary artery Perforation, interlayer tearing, lesser internal diameter influence more instrumentations etc..And surgery cost is increased, aggravate burden of patients.

Utility model content

Purpose of the utility model is to solve disadvantages existing in the prior art, and the one kind proposed is used for coronary heart disease The device of clinical medical protective cradle conveying.

To achieve the goals above, the utility model adopts the technical scheme that

Design a kind of device for the clinical medical protective cradle conveying of coronary heart disease, including core, the right side of the core Side is socketed with head end sheath, and the length of the head end sheath is 30cm, and the head end sheath includes plastic sheath, spring ring The right end of sheath, the spring ring sheath is connect with head end, and the core includes cylindric push rod, taper transition, soft Soft segment, the taper transition are located between cylindric push rod and soft section, and the taper transition and soft section are located at modeling Expect the inner cavity of sheath, and the soft section extends to the inner cavity of spring ring sheath, the head end far from one end of taper transition Sheath is connected with head end far from one end of core, and the head end is Shaping Ribbon moulding seal wire, the core and head end Between connect there are distance and by plasticity seal wire, be connected with bracket mantle on the outside of the core, the core, head end protect It covers, the outer surface of bracket mantle is coated with coating.

Preferably, the bracket mantle is high resiliency ultrathin membrane, and the length of the bracket mantle is 15-30mm.

Preferably, the coating is hydrophilic polymer coating.

The utility model proposes a kind of device for coronary heart disease clinical medical protective cradle conveying, beneficial effect exists It can be simple and efficient that solve coronary artery blood vessel close by the way that bracket is inserted in support casing film in coronary intervention in: the utility model Section has placed bracket, needs to be implanted into bracket bracket again by proximal segment brace sections and is difficult to pass through, and needs by some When distorting calcification lesion bracket be difficult to by the problem of, and can be very good protective cradle, anti-anti-avulsion carries and impaired.This is practical new Bracket mantle in type can play protective cradle well and increase the passability of bracket in bracket conveying, meanwhile, it deposits In different Design of length, the demand of clinically different length bracket can satisfy, which can not only preferably make bracket easy In distorting by calcification and be implanted into brace sections, and can be to avoid the deformation of bracket and impaired.It can be intervened in percutaneous coronary Treatment encounters calcification distortion lesion and encounters when need to be by blood vessel proximal segment brace sections, and what is be simple and efficient passes through lesion by the present apparatus And brace sections, to improve success rate of operation and save operating time, practicability is stronger, promotes the use of after being worth.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-3, a kind of device for the clinical medical protective cradle conveying of coronary heart disease, including core 2, core 2 Right side be socketed with head end sheath 3, head end sheath 3 is connected with head end 1 far from one end of core 2, and head end 1 is Shaping Ribbon moulding seal wire can satisfy various moulding requirements, convenient for passing through tortuous lesion.

It connects there are distance and between core 2 and head end 1 by plasticity seal wire, the length of head end sheath 3 is 30cm, and head Holding sheath 3 includes plastic sheath 31, spring ring sheath 32, and the right end of spring ring sheath 32 is connect with head end 1, and core 2 includes There are cylindric push rod 21, taper transition 22, soft section 23, taper transition 22 is located at cylindric push rod 21 and soft section Between 23, taper transition 22 is located at the inner cavity of plastic sheath 31 with soft section 23, and soft section 23 is far from taper transition 22 One end extend to the inner cavity of spring ring sheath 32, be easy to through tortuous calcification lesion.

The outside of core 2 is connected with bracket mantle 4, and bracket mantle 4 is high resiliency ultrathin membrane, and the length of bracket mantle 4 is 15-30mm, bracket can be inserted in mantle, pass through with seal wire, then fix bracket, and seal wire is pushed to distal end, makes to mould Expect that sheath 31 and bracket are detached from, is withdrawn from after discharging bracket, it is very useful.

Core 2, head end sheath 3, bracket mantle 4 outer surface be coated with coating 5, coating 5 is hydrophilic polymer coating, can With good protective effect.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
