The angiocarpy sacculus dilating catheter has the advantages that the sacculus dilating catheter is made of Nylon 12 and PEBAX with good biocompatibility and high pressure resistance, has good adaptability, large bursting pressure, unique structure and high safety, can be applied to interventional therapy on congenital stenosis of pulmonary valve, aortic stenosis and other diseases, and adopts single lumen sleeved sacculus structure to lead smoothness of injection and pumpback; the connection of the sacculus and the canal adopts welding process, the sacculus and the canal are integrated to greatly reduce the risk of pressuring breaking; and the thread lumen and the injection lumen are respectively arranged to reduce the risk of liquid leakage.
Description
Technical field
The present invention relates to a kind of dilating catheter for the treatment of cardiovascular disease, particularly a kind of angiocarpy sacculus dilating catheter.
Background technology
Congenital stenosis of pulmonary artery is the disease that right ventricular outflow blocks, and is comparatively common congenital heart disease, accounts for 8% of congenital heart disease sickness rate.It is narrow to be divided into valve portion, infundibulum, pulmonary trunk and branch according to narrow position, and simple outflow tract of right ventricle blocks so that pulmonary stenosis more to be seen, accounts for 80～90%.The infundibulum stenosis of pulmonary artery is extremely rare.The depletion of and insecondary right heart function plump for the carrying out property of further increasing the weight of of preventing that right ventricular outflow from blocking, right ventricle, need the patient that slight above outflow tract of right ventricle blocks be treated, the endovascular stent technology of percutaneous sacculus pulmonary artery plasty and in recent years development becomes the prefered method that the simple right ventricular outflow of present treatment blocks.
The interventional therapy of congenital heart disease mainly contains that stopper is stifled to be closed and two major techniques of balloon expandable, congenital defects such as ASD, VSD, PDA are used the stifled art treatment of closing, then use the balloon dilatation treatment for pulmonary stenosis (PS), aortic stenosis diseases such as (PA).Intervention diagnosis and treatment: open an osculum on blood vessel, the method for Clinics and Practices is carried out at positions such as conduit intravascular arrival heart.
Two during the last ten years, the accumulation of a large amount of PBPV art Clinical Experience and by indication, methodology, the postoperative of PBPV are followed up a case by regular visits to data etc. carries out go deep into comparative study and the sacculus dilating catheter material is updated, PBPV has become the prefered method of the simple pulmonary stenosis of treatment, at the alternative surgery open chest surgery of most of case PBPV.
At present, in the interventional therapy of pulmonary stenosis (PS), aortic stenosis diseases such as (PA), adopting balloon material mostly is PET, and tube material is the sacculus dilating catheter of PVC.
Because the sacculus precision of this sacculus dilating catheter is higher, also corresponding higher to the requirement of mould and equipment, difficulty of processing is bigger, and scrappage is higher; Because sacculus is connected the requirement of technology with conduit, higher to the welding equipment requirements, the corresponding raising of processing cost.
Summary of the invention
The objective of the invention is to provide a kind of: the angiocarpy sacculus dilating catheter that make easily, processing cost is low.
The object of the present invention is achieved like this: this dilating catheter includes inner chamber joint, connection wye, protective casing, liquid injection port, conduit, marker loop and sacculus; connection wye one end is connected with the inner chamber joint; one end is a liquid injection port; one end is connected with conduit and protective casing is housed, and at the front end of conduit sacculus is arranged.
Described conduit is two single lumen catheter sleeve structures, be divided into inner catheter and outer catheter, inner catheter all is connected with connection wye with outer catheter, and the sacculus two ends are welded on the outer catheter, inner catheter passes sacculus and becomes tip configurations in the end, and two marker loops are arranged on the inner catheter at sacculus position; Be an airtight cavity between inner catheter and the outer catheter, this cavity communicates with liquid injection port, and the inner catheter inner chamber is a guidewire lumen.
Beneficial effect: owing to adopted such scheme, duct portion adopts two single lumen catheter sleeve structures, the sacculus two ends are welded on the outer catheter, inner catheter passes sacculus and becomes tip configurations at far-end, the sacculus inner catheter has two marker loops, in order to indicate effective length of balloon position in vivo, the near-end of foley's tube is equipped with handle, handle comprises breeches joint and inner chamber joint, breeches joint is connected in interior outer catheter, form an airtight cavity between inner catheter outside and outer catheter inside, this airtight chamber communicates with liquid injection port, is used for the fluid injection pressurization; The inner chamber joint docks with the breeches joint spiral, has formed airtight seal wire cavity, is used for the importing of guide wire.This dilating catheter is made easily, processing cost is low, has reached purpose of the present invention.
Advantage: the material of this sacculus dilating catheter adopts better and withstand voltage stronger Nylon 12 of biocompatibility and PEBAX; Compliance is better, and burst pressure is big; The structure uniqueness, safe.
This sacculus dilating catheter can be applied to the interventional therapy of diseases such as congenital stenosis of pulmonary valve, aortic stenosis, adopts single lumen catheter socket balloon structure, and fluid injection and pumpback are freely smooth and easy; Sacculus is connected the employing welding procedure with conduit, sacculus and conduit are integrated, greatly reduces the damaged risk of pressurization; Conduit is connected the split type helical structure of employing with connection wye, install respectively in guidewire lumen and fluid injection chamber, has guaranteed the bonding strength of conduit and connection wye, reduces the leakage risk.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Among the figure, 1, the inner chamber joint; 2, connection wye; 3, protective casing; 4, conduit; 5 marker loops; 6, sacculus; 7, liquid injection port.
The specific embodiment
Embodiment 1: this dilating catheter includes inner chamber joint 1, connection wye 2, protective casing 3, liquid injection port 7, conduit 4 and sacculus 6; connection wye 2 one ends are connected with inner chamber joint 1; one end is that liquid injection port 7, one ends are connected with conduit and protective casing is housed, and at the front end of conduit 4 sacculus 6 is arranged.
Described conduit 4 is two single lumen catheter sleeve structures, be divided into inner catheter and outer catheter, inner catheter all is connected with connection wye 2 with outer catheter, and sacculus 6 two ends are welded on the outer catheter, inner catheter passes sacculus and becomes tip configurations in the end, and two marker loops 5 are arranged on the inner catheter at sacculus position; Be an airtight cavity between inner catheter and the outer catheter, this cavity communicates with liquid injection port, and the inner catheter inner chamber is a guidewire lumen.
Operation principle: utilize the incompressible principle of liquid, select the sacculus of suitable big or small external diameter, the radial power of its generation can make the lobe leaf have a common boundary to merge part from, pulmonary orifice is blocked is removed, pressure reduces.Indivedual boundary fusion portions tough and tensile or interface amixis and single-lobe deformity person, balloon expandable can cause the lobe leaf central part or the lobe point is torn, and can cause the moderate pulmonary incompetence, still can improve the state that pulmonary artery blocks.
During use, utilize conventional puncture method, shift guide wire onto position, the dilator blood vessel dilating is selected the foley's tube specification so that sacculus dilating catheter enters, and pushes sacculus dilating catheter to the valve of pulmonary trunk place, sacculus pressurization expansion, pumpback liquid withdraws from foley's tube, measures pressure gradient, reaches therapeutic purposes.
