Step 5: it completes the cutting of narrow diseased region and is making after infiltration has drug on narrow diseased region, by leading Managing the developer solution in the pressure pump negative pressure extracting balloon body (1) of (2) end shrinks balloon body (1), then by sacculus master Body (1) detaches to carry out next step operation from patient vessel.

Technical field

The present invention relates to dilating sacculus technical field, specially a kind of inserted dilating sacculus.

Background technique

Dilating sacculus is a kind of medical intervention equipment, and being widely used in coronary artery stenosis lesion is having Serious Stenosis hat The processing of arteries and veins lesion usually first uses conventional expansion balloon expandable stenotic lesion, for the disease of Serious Stenosis or calcification Become, pre-processed using Cutting balloon it is narrow, realize sufficiently expansion and then use medicinal balloon.It adds medicine to lesion When, usually by drug coat on the surface of sacculus, and balloon surface coating is easy to be washed away by blood flow to wash away some drugs, remains Drug at target lesion position remains little, while drug is easy at target lesion inner skin surface to be scratched back and forth by instrument after expansion Influence, cause drug to fall off again a part, and blood vessel with the movement of heart and the wriggling of blood vessel itself, and will lead to The drug moiety applied at target lesion blood vessel endothelium position is lost, and leads to the reduction of drug effect, in consideration of it, it is proposed that one kind is inlayed Formula dilating sacculus.

Summary of the invention

The purpose of the present invention is to provide a kind of inserted dilating sacculus, to solve mentioned above in the background art ask Topic.

To achieve the above object, the invention provides the following technical scheme:

A kind of inserted dilating sacculus, including balloon body, the inside of the balloon body offer inner cavity, the inner cavity Inner surface at offer multiple annular grooves, the casing of hollow shape is equipped at the medium position of the inner cavity, the balloon body Outer surface offers multiple cutter grooves, and the cutter groove is in polycyclic distribution on the surface of the balloon body, and the annular groove is located at institute The rear side of cutter groove is stated, the quantity of the annular groove is equal with the number of rings of the cutter groove, and blade, the cutter groove are equipped in the cutter groove Slot bottom at offer drug slot.

As a preference of the present invention, the bottom face of the cutter groove takes the form of inclined plane, at the side end face of the cutter groove described in The front end of balloon body offers the caulking groove for installing the blade on the side end face of the cutter groove.

As a preference of the present invention, the head of the blade is in recessed crescent structure, the tail portion of the blade is equipped with Knife handle, the knife handle are embedded in the caulking groove, and the edge of the knife handle end is equipped with the chimb of convex, and the chimb protrudes into In the inner wall of the caulking groove.

As a preference of the present invention, the end of the balloon body is equipped with conduit, the conduit is in hollow tubular structures, institute The end for stating conduit is equipped with connector, offers cavity, the inside of the conduit and the cavity phase at the terminal surface of the connector Connection, the cavity are connected with the inner cavity by the conduit.

As a preference of the present invention, a pair of finger wing being symmetric is equipped at the medium position of the connector outer surface, The end of the connector outer surface is equipped with external screw thread.

As a preference of the present invention, be socketed with seal wire in the conduit, the head end of the seal wire is from the balloon body End penetrates and is pierced by from the head end of the balloon body, and the seal wire is socketed in the inside of described sleeve pipe.

As a preference of the present invention, the end of the seal wire is extend into the connector along the conduit, the conduit End is equipped with the end in cross-shaped structure, and the maximum width of the end end face is greater than the internal diameter of the conduit.

As a preference of the present invention, its application method the following steps are included:

Step 1: when balloon body is in contraction state, the head of seal wire is extended through narrow in patient vessel At narrow diseased region, and the hemadostewnosis lesion for pushing balloon body that balloon body is made to enter along seal wire patient by conduit At position；

Step 2: when balloon body is moved at the narrow diseased region in blood vessel along the blood vessel of patient, by connector It is closely connect with the pressure pump for being filled with contrast agent, the contrast agent for helping development is enable to pass through conduit under the action of pressure pump It is filled into balloon body, with being constantly filled with for contrast agent, interior intracavitary pressure rises, and makes to expand under balloon body；

Step 3: with the expansion of balloon body, the bottom surface of cutter groove is straightened, simultaneously because the balloon body wall at annular groove It is thick relatively thin, keep the surface tension of balloon body at annular groove larger, so that the side for pulling the lateral position of cutter groove to make cutter groove is inclined Tiltedly, the head of blade is further made to tilt and open from cutter groove；

Step 4: with the opening of blade, blade cuts the hard patch at diseased region narrow in blood vessel, So that the surface of narrow diseased region is cut out small curved indentations, while being filled in the narrow medicine again of the anti-hemostatic tube in drug slot Object enables drug from disengaging in drug slot and equably permeates the quilt on narrow diseased region surface with the tilting of blade In the dent that blade is cut out, at this time since the micro-incision direction cut open is to drive in the wrong direction upwards, it is open towards coronarius close End, it is just contrary with blood flow, thus greatly reduced medicinal balloon after original common Cutting balloon cutting be easy it is suitable The lost and loss of bring drug is washed away to by blood；

Step 5: it completes the cutting of narrow diseased region and is making to lead to after infiltration has drug on narrow diseased region The developer solution crossed in the pressure pump negative pressure extracting balloon body of catheter tip shrinks balloon body, then by balloon body from trouble It is detached in person's blood vessel to carry out next step operation.

Compared with prior art, the beneficial effects of the present invention are:

1. the inserted dilating sacculus makes balloon body swollen by the multiple blades being embedded at balloon body surface When swollen, blade is opened from balloon body, so that the inserted dilating sacculus had not only been had the planning function of conventional expansion sacculus but also has There is the cutting function of Cutting balloon；

2. the inserted dilating sacculus, is prevented by the way that the drug slot at the slot bottom of cutter groove is arranged in, and is filled in drug slot Blood vessel narrow drug again, makes balloon body after expansion opens blade, the drug in drug slot is detached from from drug slot, after disengaging Drug penetrate under the cutting of blade in the dent that blade is cut out and be firmly coated on vascular wall, solve to lesion When place's medicine-feeding, usually by drug coat on the surface of sacculus, and balloon surface coating is easy to be washed away by blood flow to wash away part medicine Object, the drug for remaining in target lesion position remain little, while drug is easy by instrument at target lesion inner skin surface after expansion The influence scratched back and forth causes drug to fall off again a part, and blood vessel with the movement of heart and the wriggling of blood vessel itself, It will lead to the problem of drug moiety that applies at target lesion blood vessel endothelium position is lost, leads to the reduction of drug effect again.
