Description
This utility model relates to a kind of medical apparatus and instruments that utilizes Wicresoft to hinder interventional method treatment cardiovascular disease, relates in particular to a kind of two sacculus holder devices of exchanging subcutaneous puncture coronary artery expansion plasty that do not need.
Owing to multiple reason, the situation of suffering from cardiovascular disease is high, and is as multiple coronary heart disease such as myocardial infarctions, perhaps too high because of blood fat in the blood, and blood viscosity is higher, when blood flowed in blood vessel, hyperlipidemia and full-bodied hemafecia were piled up on blood vessel, cause that vascular wall thickens, make the negotiable pipeline of vessel inner blood diminish even block, cause the cardiovascular disease that consequence is even more serious thus, for this reason, above-mentioned cardiovascular disease must be done the operation that arteriectasia is shaped.
The operation method that arteriectasia is shaped has multiple, is to represent the highest in the world operation level, also is the main trend that whole world medical profession does not develop and utilize Wicresoft to hinder interventional method treatment cardiovascular disease.On behalf of Wicresoft, " subcutaneous puncture coronary artery expansion plasty " (hereinafter to be referred as PTCA) hinder the high-tech level of interventional therapy, it is by subcutaneous puncture one sacculus dilating catheter to be introduced in the blood vessel, and the stenotic lesion place that the sacculus in the sacculus dilating catheter is partly got involved in the human body cardiovascular expands, or carry out other treatment, to alleviate or thoroughly to treat various cardiovascular disease, operation finishes, and sacculus is shunk with conduit and with outside the conduit lead body again.
At present represent the PTCA sacculus holder device of top level that two kinds of patterns are arranged in the world: a kind of is coaxial-type (OTW), be quick exchange formula (REX), the fundamental difference of the PTCA conduit of above-mentioned two kinds of patterns is, in coaxial-type (OTW) sacculus holder device, the length requirement of seal wire is very long, so the exchange of seal wire is quite time-consuming; Developed quick exchange formula (REX) thus, it is quick and convenient to make it to change seal wire.When clinical use, coaxial-type (OTW) needs two doctors operation that undergos surgery, and quick exchange formula (REX) then only needs a doctor can finish the overall process of operation technique.
Yet, no matter be coaxial-type (OTW) sacculus holder device, or quick exchange formula (REX) sacculus holder device, all necessary in use product with two kinds of forms, a kind of being referred to as " PTCA sacculus dilating catheter " is another kind of to be " PTCA scaffold tube ".In whole PTCA operation process, no matter adopt coaxial-type (OTW) (can be described as not only rear-mounted) still the PTCA foley's tube of quick exchange formula (REX) (but also can be described as forward type) all unavoidably at first the sacculus of " PTCA sacculus dilating catheter " partly be got involved in the interior stenotic lesion place of human body cardiovascular and expand, make blood vessel recover normal back and take out conduit, change one " PTCA scaffold tube " again and enter into the position that the cardiovascular stenosis has been passed through predilation, take out conduit after discharging support, this secondary interventional procedure method is called " switch type ".
Know from above-mentioned, existing " PTCA sacculus dilating catheter ", " PTCA scaffold tube " develop into REX (quick exchange formula or forward type) from OTW (coaxial-type or rear-mounted) and consider from the operation of operation, make two doctor's operations change to a doctor and can finish operative process, but, no matter OTW still is REX is all failed to solve the process that conduit is got involved the patient vessel for twice, and twice intervention of conduit not only increases patient's misery, and increased the expense of operation.
The purpose of this utility model is to provide a kind of improved a kind of two sacculus holder devices of exchanging subcutaneous puncture coronary artery expansion plasty that do not need, it has changed prior art operation technique method, makes the operation of subcutaneous puncture coronary artery expansion plasty not need to carry out the conduit exchange and can once can finish.
