Description
Technical field
The present invention relates to heart disease surgical minimally-invasive treatment technical fields, specifically provide a kind of surgery mitral stenosis
Balloon expandable instrument set group.
Background technology
With the rapid development of social economy, people's lives level is greatly improved, but simultaneous
The pressure of life and work is increasing, leads to the health for various sickness influence people occur.Wherein mitral stenosis is
A kind of common rheumatic heart disease, seriously affects the life of patient.Have at this stage to the therapeutic modality of mitral stenosis routine
Two kinds：One is open surgeries, and after establishing extracorporal circulatory system, the heart of patient is cut, after narrow bicuspid valve excision,
Implantable prosthetic valve.Second is internal medicine under X-ray, and by a series of intervention modus operandi, dilating sacculus is transported to two
At cusp mouth, balloon expandable is carried out.For the mitral stenosis of severe calcification, can only select to operate on heart valve replacement surgery, biovalve
Service life is very short, only the service life of 10-15, and valvular metal needs take anticoagulant all the life.Slight mitral stenosis,
And narrow serious but lighter calcification patient, preferred balloon expandable.But because the internal medicine under X-ray intervenes balloon dilatation, because
Longer for operation pathway, instrument is complex, and operation difficulty is very high, causes success rate relatively low, and usually occur it is serious simultaneously
Disease is sent out, is substantially eliminated now.
Invention content
In order to solve the above problems, the present invention provides a kind of reasonable in design, simple to operate to be easy to slap
It holds, surgery mitral stenosis balloon expandable instrument set group low to Doctors' skill level requirement, minimally invasive and safe.
To achieve the above object, the present invention provides following technical solutions：
A kind of surgery mitral stenosis balloon expandable instrument set group, is led by puncture sheath, puncture needle, pre- curved conductor, pre-bending sacculus
Pipe, guiding steel wire, sacculus are oriented to steel wire and syringe is constituted, and the puncture sheath is provided in the axial direction with hollow cavity, and puncture needle passes through
Hollow cavity；Pre- curved conductor is provided in the axial direction with pilot hole, is oriented to steel wire and runs through pilot hole, pre- curved conductor leading portion is equipped with bending angle
Degree；The pre-bending foley's tube is provided in the axial direction with directed cavity, and pre-bending foley's tube leading portion is equipped with bending angle, and pre-bending sacculus is led
Pipe front end is equipped with sacculus, and sacculus is oriented to steel wire and runs through directed cavity, and it is soft that sacculus is oriented to steel wire leading portion；Pre-bending foley's tube edge
One or several endoporus axially are further opened with, endoporus tail end is connected with syringe, and endoporus front end extends to sacculus front end
Position, position corresponding with sacculus offers several deflector holes on pre-bending foley's tube, and endoporus passes through deflector hole and sacculus phase
Connection.
The syringe is common medical syringe in the prior art.Liquid is contained in syringe, is pressurizeed to syringe
When, liquid flows into endoporus, then is flowed into Filled Balloon in sacculus by deflector hole, makes the bicuspid valve valve mouth that balloon expandable is narrow
Place.
The sacculus, which is oriented to steel wire leading portion softness, can be adapted to the curvature of pre- curved conductor leading portion, and adaptation pre-bending sacculus is led
The curvature of pipe leading portion.
During use, puncture needle passes through the hollow cavity of puncture sheath, and puncture sheath enters trouble under the guiding function of puncture needle
Person atrium, withdraws from puncture needle, is implanted into along puncture sheath hollow cavity and is oriented to steel wire, withdraws from puncture sheath, and pre-bending is implanted into along steel wire is oriented to
Conduit withdraws from guiding steel wire, and the pilot hole implantation sacculus along pre- curved conductor is oriented to steel wire, so that sacculus is oriented to steel wire front end and enters the heart
Pre- curved conductor is withdrawn from room, and being oriented to steel wire along sacculus is sent into pre-bending foley's tube, and the sacculus position of pre-bending foley's tube is made to reach two
At cusp valve mouth.Rapid pressure injector, the liquid in syringe enter sacculus, by Liquid-Filled Balloon, make balloon expandable
Then narrow bicuspid valve quickly draws back liquid, balloon deflation, pre-bending foley's tube is oriented to steel wire along sacculus and withdraws from heart,
Sacculus is withdrawn from simultaneously is oriented to steel wire.
Preferably, the guiding steel wire, sacculus, which are oriented to steel wire tail end, is respectively equipped with scale.
The depth for being oriented to steel wire, sacculus guiding steel wire insertion ventricle can be easily found out by scale value.
Preferably, the pre-bending catheter proximal end, pre-bending foley's tube front end are respectively arranged with chamfering.
The chamfer design of the pre-bending catheter proximal end makes pre- curved conductor more easily be inserted into atrium, pre-bending foley's tube
The chamfer design of front end makes in the ventricle that pre-bending foley's tube is more easily inserted into.
Preferably, the bending angle of the pre- curved conductor leading portion is 0-120 degree.
Preferably, the bending angle of the pre-bending foley's tube leading portion is 0-120 degree.
Preferably, guiding steel wire both ends softness is flexible, interlude has hardness.
Guiding steel wire both ends softness is flexible easily to guide pre- curved conductor to enter in atrium.It is oriented among steel wire
There is section hardness can be used for supporting pre- curved conductor.
Preferably, the sacculus, which is oriented to steel wire back segment, has consistency and elasticity, it may be convenient to pre-bending sacculus be guided to lead
Pipe enters in ventricle.
Compared with prior art, surgery of the invention mitral stenosis balloon expandable instrument set group has following prominent
Advantageous effect：
（One）The surgery is matched by puncture needle with puncture sheath with mitral stenosis balloon expandable instrument set group will be oriented to steel
Silk, pre- curved conductor, sacculus are oriented to steel wire and are introduced in the atrium of patient, to which pre-bending foley's tube is introduced to patient's ventricle
In, so that narrow bicuspid valve is expanded by the balloon expandable of pre-bending foley's tube front end, to make the disease of patient's mitral stenosis
Shape disappears, and achievees the purpose that treatment；
（Two）The surgery is reasonable in design with mitral stenosis balloon expandable instrument set group, simple to operate, to doctor's skill
Art level requirement is low, is easy to grasp, minimally invasive and safe, and balloon expandable is unsuccessful can also then to carry out conventional operating on and change valve hand
Art not only gives the more minimally-invasive treatment chances of patient, but also can guarantee the safety of patient, has good practicability.
