The invention discloses an over-selection catheter with good fixing effect, which comprises a catheter body 1 and a guide wire 2, wherein the guide wire 2 is arranged in the catheter body 1 in a penetrating manner; the catheter body 1 is provided with a fixing hole 11, and the guide wire 2 penetrates through the fixing hole 11 while penetrating through the catheter body 1.
When the catheter is specifically applied, the catheter body 1 can select any one of a single bent pipe, a double hook, a hunter head, a special pipe, a simmons wire series, a pigtail pipe and a cobra pipe according to different physiques and blood vessel distribution conditions of each person so as to meet the requirements of different occasions.
The guide wire 2 comprises a guide wire 21 and a fixing wire 22, the guide wire 21 is arranged in the catheter body 1 in a penetrating manner, the fixing wire 22 is arranged in the catheter body 1 in a penetrating manner, and one end of the fixing wire 22 penetrates through the fixing hole 11. When the guiding wire is specifically applied, two ends of the guiding wire 21 are respectively exposed out of two end parts of the catheter body 1, and two ends of the fixing wire 22 are respectively exposed out of one end of the catheter body 1 and the fixing hole 11, so that the trend of the catheter body 1 can be controlled conveniently. Preferably, the guide wire 21 and the fixing wire 22 are selected from two different colors, so that the guide wire and the fixing wire can be distinguished conveniently during use, and misoperation can be prevented.
Referring to fig. 3, fig. 3 is a structural diagram of the super catheter with good fixing effect in the embodiment. As shown in the figure, preferably, the fixed effectual super select pipe still includes pipe seat 3, and pipe seat 3 cover is located the one end that pipe body 1 is kept away from fixed orifices 11, through the setting of pipe seat 3, is favorable to the control to pipe body 1 direction, advance and rotation in the use for pipe body 1 can be more accurate reach corresponding position. During the specific application, the both sides of pipe seat 3 are equipped with flange 31, and the flange 31 symmetry of both sides sets up, and convenient to use person acts on pipe body 1.
