Therefore, how to solve the problem of ensuring the rapidness, the accuracy and the convenience of the rapid exchange balloon type interventional operation is worthy of research. The specific structure and function of the rapid exchange balloon system will be described in detail below.
Referring to fig. 1 to 5, the present invention discloses a rapid exchange balloon system, including: a catheter 1, a rapid exchange balloon catheter 2 and a guide wire 3;
specifically, the catheter 1 comprises a catheter proximal end 101, in the rapid exchange balloon system, the catheter 1 serves as an external member, the rapid exchange balloon catheter 2 and the guide wire 3 can be accommodated in the catheter 1, and the rapid exchange balloon catheter 2 and the guide wire 3 can be inserted from the catheter proximal end 101, so that the operation is convenient, and the rapid exchange balloon catheter 2 and the guide wire 3 are effectively protected;
the rapid exchange balloon catheter 2 is inserted into the catheter 1 and comprises a movable distal end of the rapid exchange balloon catheter and a guide wire rapid port located on the wall of the catheter, the rapid exchange balloon catheter 2 generally comprises a balloon part and a catheter part, the balloon at the distal end of the rapid exchange balloon catheter can be expanded to a specified diameter under specified pressure, and the distal end of the rapid exchange balloon catheter is inserted into the catheter 1 and can move along the length direction of the catheter 1, so that the distal end of the rapid exchange balloon catheter can move to a focus of a patient, and the focus can be conveniently treated; and
seal wire 3, including rotatable seal wire near-end 301 and mobilizable seal wire distal end 304, seal wire distal end 304 can run through seal wire fast mouthful and quick exchange sacculus pipe distal end, seal wire near-end 301 of seal wire 3 can rotate, it can carry out the angle deflection to have decided the seal wire distal end 304, seal wire distal end 304 can remove, the distance that seal wire 3 can move has been decided, thus, rotation and the removal of seal wire distal end 304 through seal wire near-end 301, two kinds of motion mode superpose in seal wire distal end 304, can realize the mode of walking of the helix of seal wire 3, the mode of walking on the basis of this helix, make quick exchange sacculus system can accurate duplication doctor's action, guarantee the operation of interveneeing fast, accurate and convenient. In addition, because the guide wire 3 can penetrate through the far end of the rapid exchange balloon catheter and the guide wire rapid port, the extension guide wire 3 is not needed when the rapid exchange balloon catheter 2 is replaced.
The guide wire 3 is arranged between the guide wire proximal end 301 and the catheter proximal end 101 in a bent mode, and it can be understood that the guide wire proximal end 301 and the catheter proximal end 101 which are fixed in position are arranged at intervals, namely, the distance between the guide wire proximal end 301 and the catheter proximal end 101 is fixed, during the interventional operation treatment process, the guide wire proximal end 301 is fixed in position, and the guide wire distal end 304 is inserted into the catheter proximal end 101, so that the guide wire outer portion is formed on the guide wire portion located outside the guide wire proximal end 301 and the catheter proximal end 101, and the guide wire outer portion is always in a bent state. The position of the guide wire near end 301 does not need to be adjusted according to the movement of the guide wire far end 304, and the guide wire is bent and can be moved orderly, so that the rapidness, the accuracy and the convenience of the interventional operation are ensured.
Alternatively, the catheter 1 may be a medical catheter with a certain inner diameter and has two catheter ends, one of which is the proximal catheter end 101, and a system mounting seat may be included in the rapid exchange balloon system, and the proximal catheter end 101 may be fixedly mounted on the system mounting seat, and the mounting seat may be a plate structure or a frame structure, which is not limited in this respect.
Alternatively, for the rapid exchange balloon catheter 2, two balloon catheter ends may be included, one as the rapid exchange balloon catheter distal end and the other as the rapid exchange balloon catheter proximal end, having an outer diameter smaller than the inner diameter of the catheter 1, and thus, may be inserted into the catheter 1 and be able to move inside the catheter 1. The proximal end of the rapid exchange balloon catheter may have a female luer fitting that may be connected to a device capable of performing inflation procedures to adjust the balloon size. In addition, the material of the rapid exchange balloon catheter 2 needs to meet medical requirements, for example, the balloon section of the rapid exchange balloon catheter 2 may be a polyether amide block copolymer, and the catheter section may be a polyether amide block copolymer, although the material of the rapid exchange balloon catheter 2 is not limited thereto.
Optionally, for the removability of the distal end of the rapid exchange balloon catheter, the rapid exchange balloon catheter 2 may be clamped by a wheel set, and at this time, the rotation of the wheel portion of the wheel set may be converted into the linear movement of the rapid exchange balloon catheter 2, so that the distal end of the rapid exchange balloon catheter may be accurately and efficiently controlled to move to the designated focus.
Optionally, for the guide wire 3, the guide wire 3 can guide the catheter 1 to move to a specified position, and the guide wire 3 plays a role in guiding, positioning and supporting in the rapid exchange balloon system, so that the catheter can enter blood vessels and other cavities, and the guide catheter can smoothly reach a focus, so that accurate control of the guide wire 3 is a necessary condition for accurately copying the actions of medical staff.

Optionally, the proximal guide wire end 301 and the proximal catheter end 101 are fixed in position, and they may be spaced apart from each other on the system mount, i.e., they are fixed in distance. Because the distal end 304 of the guide wire is inserted into the proximal end 101 of the catheter, the guide wire 3 can be bent between the proximal end 301 of the guide wire and the proximal end 101 of the catheter through the limiting piece, so that the position of the proximal end 301 of the guide wire does not need to be adjusted according to the movement of the distal end 304 of the guide wire, the guide wire is bent and can be moved orderly, and the rapidness, the accuracy and the convenience of an interventional operation are guaranteed.
