Problems solved by technology

[0006] The present invention provides a coronary artery cutting balloon and its catheter, which avoids drug shedding during the process of the cutting balloon being guided into the human body, and solves the defects that the existing cutting balloon has poor dimensional stability and cannot prevent acute elastic recoil. ; While improving the mechanical strength and dimensional stability of the cutting balloon, the blood solubility of the balloon material is reduced, and the biocompatibility of the balloon material is improved, so that the coronary artery cutting balloon has good mobility in the blood, and less likely to cause blood clots

Embodiment 1

[0072] see Figure 1-4 , the present invention provides a technical solution: a coronary artery cutting balloon and its catheter, including a balloon body 1, one end of the balloon body 1 is fixedly connected with a guide wire 2, and the distal guide wire 2 of the balloon body 1 One end of the wire 2 is provided with a catheter groove 3, the inner cavity of the catheter groove 3 is fixedly connected with a catheter 4, and the outer ring of the catheter 3 is fixedly connected with an expansion inflation tube 5, and the middle part of the inner cavity of the balloon body 1 is connected to There is an inner catheter 6, the inner cavity of the balloon body 1 is provided with a blade groove 7, the inner cavity of the blade groove 7 is movably connected with a cutting blade 8, and the inner cavity of the balloon body 1 is provided with a drug storage tank 9 , the inner wall of the drug storage tank 9 is fixedly connected with a leak-proof sheet 10, and the inner cavity of the drug s...

Embodiment 2

[0077] A coronary cutting balloon and catheter thereof, the specific implementation method is the same as that in Example 1. The difference lies in that the material of the coronary artery cutting balloon is modified nylon 6.

[0078] The raw materials for preparing the modified nylon 6 include: in parts by weight, 52 parts of nylon 6 masterbatch, 2 parts of glycidyl ester, 10 parts of inorganic filler, 8 parts of hydroxyl compounds, and 4 parts of plant extract.

[0079] The nylon 6 masterbatch was purchased from Sinopec Baling Branch, the model is BL 1340H.

[0080]The inorganic filler is 200-mesh diatomite, which is purchased from Guangzhou Yikang New Material Technology Co., Ltd.

[0081] The glycidyl ester is glycidyl 4-tert-butylbenzoate, and the CAS number is 59313-58-5.

[0082] The hydroxy compounds are 2,3-dihydroxybenzenesulfonamide, 2-hexyloxypropane-1,3-diol and glycerol, 2,3-dihydroxybenzenesulfonamide, 2-hexyloxypropane-1, The mass ratio of 3-diol and glyceri...

Abstract

The invention relates to the technical field of medical instruments, in particular to a coronary artery cutting balloon and a catheter thereof. The coronary artery cutting balloon comprises a balloonbody 1. A guide wire is fixedly connected to one end of the balloon body; a catheter groove is formed in the end, away from the guide wire, of the balloon body; a catheter is fixedly connected to an inner cavity of the catheter groove; an expansion inflation tube is fixedly connected to the outer ring of the catheter; an inner catheter is connected to the middle of the inner cavity of the balloonbody in a penetrating mode; a blade groove is formed in an inner cavity of the balloon body; a cutting blade is movably connected to an inner cavity of the blade groove; a medicine storage groove is formed in the inner cavity of the balloon body; a leakage-proof piece is fixedly connected to the inner wall of the medicine storage groove; and medicine is contained in the inner cavity of the medicine storage groove. According to the coronary artery cutting balloon and the catheter thereof, medicine can be prevented from falling off in the process that the cutting balloon is guided into a human body, the cutting balloon has relatively high size stability and biocompatibility, mobility in blood is good, and blood agglutination is not likely to be caused.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a coronary artery cutting balloon and a catheter thereof. Background technique [0002] Interventional therapy is the third major treatment method between surgery and internal medicine. At present, it is an extremely important treatment method in cardiovascular, cerebrovascular, peripheral vascular, tumor or non-vascular fields. Simply put, interventional therapy It is a minimally invasive treatment method that treats the lesion locally under the guidance of imaging technology equipment by percutaneous puncture or the original channel of the human body without exposing the lesion by surgery. [0003] Cutting balloons have appeared in medical devices. Cutting balloons use the blades on the outer ring of the balloon to cut the vascular lesion while expanding. During interventional treatment, the wound needs to be hemostasis and disinfected after cutting, so in When the bal...
