Description
Technical field
The present invention relates to a kind of interventional medical equipment field, particularly relate to the diagnoses and treatment conduit that a kind of blood vessel is got involved.
Background technology
In recent years, along with the development of Medical Technology, interventional therapy conduit is widely applied in clinical treatment.Intravascular Interventional Treatment technology is applied to the aspects such as clinical vascular radiography, angioplasty, blood vessel intervention.Compared with traditional medical skill, intravascular Interventional Treatment technology is not only easy to operate, and Operative risk is less, and the wound of interventional therapy is low, and greatly can alleviate the misery of patient, medical expense is also relatively low.Therefore this technology is widely used at medical domain and promotes.Conduit is one of main tool of intravascular Interventional Treatment, and it generally needs to have excellent operability and safety, excellent blood compatibility and lubricity, certain blood property of softening, excellent mechanical performance and machinability etc.
Insert in the process of human body at conduit, if frictional force is larger between conduit and vascular, can make that patient vessel is broken, other tubings of interlayer have strong calcination and pain, and easily arterial intima epithelial tissue causes infection, so need catheter surface smooth, less to the inner surface damage of body cavity, reduce the injury to operator.Current medical catheter, originally as macromolecular material, does not possess lubricating function, in insertion human body process, produce larger frictional force with body cavities.In order to reduce the friction between conduit and tissue, current people apply hydrophilic superslide coating to catheter surface.As patent CN101455861A method, CN1442458A method, CN102166377A, CN1537643A, its hydrophilic layer is that various polymer and plasticizer are formed by combining, its process of smearing employs the high organic solvent system of meltage, the volatilization of these organic solvents not only brings the hidden danger in production, and contaminated environment, potential threat is all also existed to sufferer or the healthy of workman of producing conduit; Manufacture process is also complicated, and cost is high, high to preparation environmental requirement.
Conduit also may cause the problem of blood coagulation.When contacting blood is to surperficial except the natural wall of blood vessel, some recycled material is activated, thus will cause blood coagulation.If form thrombosis in the surface portion contacted with blood flow, be released there is thrombosis and the risk causing serious blood circulatory disturbance.
Locate general ct location/X-ray machine, dsa, nuclear magnetic resonance, NMR.The image documentation equipments such as excusing from death system.The general anchor point of existing interposing catheter is one, by corresponding image documentation equipment, determine the position of focus, but the method probably can only be located, can not be accurate.As the patent of Authorization Notice No. CN 202397532 U, by being provided with metal positioning ring in the spheroid of guiding tube top, but place kick shape is excessive may cover lesions position, even can cause irreversible infringement to blood vessel wall chamber.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of diagnoses and treatment conduit.
The technical solution adopted in the present invention is:
A kind of diagnoses and treatment conduit, comprise catheter main body and modular catheter, catheter main body one end is connected with modular catheter, and the catheter main body other end is soft head end, be provided with multipair wire drawing in conduit, it is characterized in that: described catheter main body is provided with the side opening of helically the linear alignment; Described soft head end is provided with the equal locating ring of 4 spacing, and described locating ring diameter is micro-is greater than catheter main body diameter, and locating ring spacing is each other 10cm, and the locating ring at soft head end top is inflation ring, and its excess-three ring is the locating ring of different metal materials; A trachea for inflating to inflation ring is provided with in described catheter main body; Described catheter main body outer surface is provided with the two coatings comprising hydrophilic coating and heparin coating.
Side opening is set along catheter main body helical form, can performs the operation to the focus of different parts, more reasonable than prior art of this design, the location of orientation angle when being convenient to perform the operation; Be navigate to from conventional point first to locate by 4 locating rings one, be convenient to radiography location, it is also more accurate to locate; By locating the seal wire that can stretch out from the side opening of many places, intubate, repeatedly diagnosis and treatment are carried out to different wound site, and repeatedly can only move conduit unlike tradition importing bobbin styl to multiple wound site; The metal material of locating ring is different, and when development, reflected signal is just different, and such location determination is easy, can determine the angle between two anchor points, determine the angle of flexible conduit, plane or three-dimensional viewpoin; After the inflation ring inflation of catheter tip, certain logical blood vessel function can be had; Locating ring diameter is greater than conduit diameter, also can play thrombus breaking to a certain extent, the effect of logical blood vessel.
Further, between described 4 locating rings, spacing is equal, and locating ring spacing is each other 10cm.
Equal by locating ring spacing, easily determine the relative distance of several ring and focus, be convenient to projective iteration time determine distance, the relative distance of such as air line distance or bending.
Further, described catheter main body surface is provided with a graduation mark.
Graduation mark the bending angle can determined between catheter main body and ring is set, also can determine the bending angle between the soft head end of conduit and catheter main body, further focal part accurately be located.
Further, described soft head end accounts for 1/5 ~ 1/2 of whole catheter main body length.
Further, described catheter length is 60cm ~ 120cm.
Further, described hydrophilic coating and heparin coating gross thickness are 30 ~ 50 μm.
Further, there are two curved control, bending locking device in described modular catheter place.
Beneficial effect of the present invention:
Adopt technical scheme of the present invention, achieve the location from point to line, and can determine the angle of bend of conduit, and stretch into the length of blood vessel when actual operation, location is more accurate, is convenient to operation radiography determination focus and operation technique.
