Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to the protective device of a kind of holder and its manufacturing method, doctor
Treat device.
Background technology
Support product is made of rack body, medication coat and ball expansion type transport system.Draw suitable for coronary artery primary affection
The ischemic heart disease risen improves coronary artery intracavitary diameter.
Used rack body includes bare metal stent, medication coat metallic support and degradable suction in the prior art
The polymer or metallic support of receipts.
The polymer support different from metallic support is expected only to retain one section of finite time in vivo.In many treatment uses
In, holder must have one section of finite time in vivo, until its expectation function is realized, for example, maintaining unobstructed blood vessel.
However, when exploitation has the transport system of polymer support, need to overcome a large amount of challenges.By comparing metal branch
Frame and polymer support prepare material, and the material for preparing polymer support has lower intensity, this needs more heteropolymer
Material is to provide and the comparable engineering properties of metal.Therefore, it is necessary to improve holder to prepare thickness and width, so that Polymer-supported
Frame has the intensity needed for support blood vessels wall.Since polymer support made of this polymer material also tends to frangible or has
The fracture toughness of limit.The intrinsic anisotropy of this polymer material can increase the processing complexity of polymer.
Metallic support can reduce the radial rebound that metal structure after head removes is held from pressure as far as possible.The base after pressure holds technique
This holding pressure holds the minimum diameter of period.This advantageous feature causes relatively to be not concerned about is ready to use in medical operating when product is packaged into etc.
When metallic support can the risk that diameter becomes larger occur at any time.And polymer support is by the shadow of the rebound characteristics of polymer material
It rings, causes original traditional single ply protective Analysis of Nested Design to cannot be satisfied the demand that polymer support maintains diameter dimension, therefore exist
Before polymer support is fixed on transport system sacculus and is transported to internal target site in stent system, remain to maintain polymerization
The diameter dimension of object holder is the challenge of the size of diameter needed for transport system.
Although medication coat metallic support has a stronger anti-radial resilience, the medication coat on surface and metal
Binding force can be at any time increase and generate variation, in order to avoid coating in manufacture, transport and storing process fall off usually
It can select in rack surface protection device for installing.
Invention content
The purpose of the present invention is to provide a kind of protective device of holder and its manufacturing method, medical treatment devices, can be branch

Mouthfuls 30, the notch 30 is axially extending along the protective sheath 3, and that the protective sheath 3 is formed as being separated from each other
A part 31 and second part 32;The first part 31 passes through the first window 20a, to guide first part opposite second
It is partially separated;The second part 32 passes through the second window 20b, to guide second part 32 to divide with respect to first part 31
From.
Further, as shown in figure 11, first window 20a and the second window 20b is opened in 2 proximal end of about bundle jacket
Body wall on, the first window 20a and the second window 20b are distributed about the axisymmetrical of the about bundle jacket 2.It please join
Figure 10 is examined, schematic diagram when to remove holder 1 from protective device in the present embodiment.In the present embodiment, first part 31
End pass through first window 20a, the end of second part 32 to pass through the second window 20b, to realize that first part 31 is opposite
Second part 32 detaches, and the opposite sliding with holder 1 of first part 31 and second part 32 is avoided, to effectively avoid holder 1
The damage and abrasion of surface layer medication coat.
<Embodiment three>
