Description

Intervene valve loading attachment
Technical field
The present invention relates to medical instruments fields, more particularly to a kind of intervention valve loading attachment.
Background technology
Normal valve can ensure the unidirectional smooth outflow of blood, can effectively pump out the blood of chamber without flowing back.Very much Kind of disease, such as rheumatic heart disease, the function that endocarditis causes the lesion of valve to make valve are damaged, narrow and backflow and be Common valvular disease.
Traditional surgery valve replacement surgery will row throacotomy, to establish extracorporal circulatory system makes cardiac arrest, needs a large amount of Manpower coordinates, and the requirement to patient is high, and operation is extremely complex.Due to operation need Cardiopulmonary Bypass to support, to patient with The wound come is larger, and for elderly patient and more complication patient, the death rate and complication are very high.In recent years, percutaneous intervention The patient that develops into of valve brings a kind of higher alternative medicine of safety.
Currently used intervention valve is broadly divided into ball according to its delivery mode and expands formula and self-inflated.Because intervening valve knot Structure design is complicated, can easily and fast be loaded valve on a conveyor by valve loading attachment.But current existing one A little loading attachments are complicated, although easy to operate, manufacturing cost is higher, need to clean and sterilize again after each use with Just it reuses, repeats sterilizing and use the risk that can increase the infection of patient's instrument.As license notification number is CN at home 101257863, authorized announcement date is on May 11st, 2011, and patent name is to disclose one in " prosthetic valve crimping device " Kind valve loading attachment, is to be combined into a periphery closed regular polygon column space using multiple wedge blocks, by each Wedge block is synchronized to be translatable to axle center, realizes regular polygon column space compression and expansion.Due to which increase external pressure device, Keep the apparatus structure complicated, manufacturing cost is high.Moreover, the device contour dimension is larger, lead to not using easy cooling side Formula (square position as being equipped with mixture of ice and water) carries out martensitic traoformation processing to recalled nitinol alloy stent, makes holder at low temperature It is recompressed after limbering up, holder is such as allowed to be compressed under austenite phase, the radial support power of several times will be generated, this has so that artificial The risk of valve device holder fracture.
Another kind of loading attachment structure is relatively easy, and manufacturing cost is low, is provided as disposable consumption product, reduces patient's friendship The risk of infection is pitched, but its cumbersome operating procedure can not reduce the operating time of operation.If Authorization Notice No. is CN 102805676, authorized announcement date is on June 17th, 2015, and patent name is in " compression set of valvular prosthetic replacement's device " A kind of device of jaw arrangement is disclosed, each clamp unit, which is sequentially connected, surrounds a scaling channel, when prosthetic valve device is put It sets when scaling in channel, by external force so that each clamp unit is collapsed to scaling channel center simultaneously, reaches the artificial valve of compression The purpose of film device.Its structure is although relatively easy, but because it is there is no the resulting structure for implementing external force is equipped with, operator is only Prosthetic valve device can be compressed by the curable grip of hand.It is restorative strong due to marmem so that operator need to hold It is continuous to hold this compression set energetically and complete to operate.
