The time of capsule dilatation, lift success rate of operation.
To achieve the above object, the utility model employs following technical scheme：
A kind of expansion of balloon catheter, including sacculus (1), developing ring (3), sheath (4), injection connector (6) and balloon cavity
(7), balloon cavity (7) is connected via injection connector (6), sheath (4) with sacculus (1), and developing ring (3) is arranged on balloon cavity (7)
Interior, sacculus (1) outer surface is provided with balloon-markers (2), the balloon-markers (2) positioned at sacculus (1) medium position and have with
Sacculus (1) visibly different color of appearance.
The balloon-markers (2) can be vertical element shape (21), oblique line strip (22), a plurality of straight line strip (23), a plurality of
Oblique line strip (24) or straight segments strip.
The sheath (4) is two lumens or three lumens.
Preferably, also including guidewire lumen (8), guidewire lumen (8) is communicated to sheath via injection connector (6), sheath (4)
(4) distal end.
Or preferably, the sheath (4) is with two quick exchange guidewire chambers otch (11).
Preferably, also including contrast agent chamber (9), contrast agent chamber (9) are via injection connector (6), sheath (4) and sheath
(4) contrast agent chamber otch (10) connection of distal end.
The utility model as a result of more than technical scheme, patient can direct view under endoscope according to balloon-markers come
Judge position of the cylinder balloon in duodenofiberscope portion, it is ensured that be located at teat sphincter in the middle of cylinder balloon, so not only
The use time of endoscopic papillary balloon dilation X-ray under scope can be reduced, x-ray is reduced to medical personnel and sufferer
Irradiation damage, and the time of endoscopic papillary balloon dilation is greatly shortened, sufferer pain is reduced, lift successful surgery
Rate.
