The rapid exchange balloon system is the most widely applied one in vascular interventional therapy, and has the main advantages that a catheter does not need to be replaced at any time in the process of operating a guide wire, the balloon dilatation catheter does not need to be replaced by extending the guide wire, a side hole is formed in the position, 25 cm away from the balloon top, of the catheter, the guide wire can be inserted from the balloon top, and the guide wire penetrates out of the side hole, so that the operation space of an operator can be facilitated. However, in the existing rapid exchange balloon system, the catheter, the rapid exchange balloon catheter and the guide wire need to be adjusted to adjust the position of the proximal end according to the movement of the distal end, the operation steps are complicated, and the operation difficulty of interventional therapy is increased. Therefore, how to solve the problem of ensuring the rapidity, the accuracy and the convenience of the rapid exchange balloon interventional operation is worth researching. 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 comprising 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 is used as an external component, the rapid exchange balloon catheter 2 and the guide wire 3 can be accommodated in the catheter, and the rapid exchange balloon catheter 2 and the guide wire 3 can be inserted from the catheter proximal end 101, so that the rapid exchange balloon catheter 2 and the guide wire 3 are convenient to operate and can be effectively protected;
A rapid exchange balloon catheter 2 inserted into the catheter 1 and including a movable rapid exchange balloon catheter distal end and a guidewire rapid port on the wall of the catheter, the rapid exchange balloon catheter 2 generally including a balloon portion and a catheter portion, the balloon of the rapid exchange balloon catheter distal end being expandable to a prescribed diameter under prescribed pressure, wherein the rapid exchange balloon catheter distal end is inserted into the catheter 1 and movable along the length of the catheter 1, such that the rapid exchange catheter distal end can be moved to a patient's lesion to facilitate treatment of the lesion, and
The guide wire 3 comprises a rotatable guide wire proximal end 301 and a movable guide wire distal end 304, the guide wire distal end 304 can penetrate through a guide wire rapid port and a rapid exchange balloon catheter distal end, the guide wire proximal end 301 of the guide wire 3 can rotate, the guide wire distal end 304 is determined to be capable of deflecting angularly, the guide wire distal end 304 can move, and the distance of the guide wire 3 which can move is determined, so that through the rotation of the guide wire proximal end 301 and the movement of the guide wire distal end 304, the two movement modes are overlapped on the guide wire distal end 304, the spiral line running mode of the guide wire 3 can be realized, and the rapid exchange balloon system can accurately replicate the actions of a doctor based on the spiral line running mode, and the rapid, accurate and convenient intervention operation is ensured. In addition, since the guide wire 3 can be threaded through the distal end of the rapid exchange balloon catheter and the rapid port of the guide wire, the guide wire 3 does not need to be lengthened when the rapid exchange balloon catheter 2 is replaced.
The guide wire proximal end 301 and the catheter proximal end 101 are arranged at intervals and are fixed in relative positions, the guide wire 3 is bent between the guide wire proximal end 301 and the catheter proximal end 101, and it is understood that the guide wire proximal end 301 with fixed positions and the catheter proximal end 101 are arranged at intervals, that is, the interval between the guide wire proximal end 301 and the catheter proximal end 101 is fixed, the guide wire proximal end 301 is fixed in position during interventional operation treatment, and the guide wire distal end 304 is inserted into the catheter proximal end 101, so that a guide wire outside 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 outside is always in a bent state. 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, and the guide wire is bent and can sequentially move, so that the rapidness, the accuracy and the convenience of the interventional operation are ensured.
Alternatively, for the catheter 1, a medical catheter having a certain inner diameter and having two catheter ends, wherein one catheter end is the proximal catheter end 101, a system mount may be included in the rapid exchange balloon system, and the proximal catheter end 101 may be fixedly mounted on the system mount, and the mount may be a plate-like structure or a frame structure, which is not particularly limited.
Alternatively, for a rapid exchange balloon catheter 2, two balloon catheter ends may be included, one of which is a rapid exchange balloon catheter distal end and the other is a rapid exchange balloon catheter proximal end, having an outer diameter smaller than the inner diameter of catheter 1, and thus being insertable into catheter 1 and movable within 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 segment of the rapid exchange balloon catheter 2 may be a polyether-amide block copolymer, and the catheter segment may be a polyether-amide block copolymer, but the material of the rapid exchange balloon catheter 2 is not limited thereto.
Optionally, for the mobility of the rapid exchange balloon catheter distal end, the wheel set may be used to clamp the rapid exchange balloon catheter 2, and at this time, the rotation of the wheel part of the wheel set may be converted into the linear movement of the rapid exchange balloon catheter 2, so that the rapid exchange balloon catheter distal end may be accurately and efficiently controlled to move to the designated lesion.
Optionally, for the guide wire 3, the guide wire 3 can guide the catheter 1 to move to a designated position, the guide wire 3 plays a role in guiding, positioning and supporting in the rapid exchange balloon system, the guide wire can help the catheter enter blood vessels and other lacunas, and the guide catheter smoothly reaches a focus, so that accurate control of the guide wire 3 is a necessary condition for accurately replicating the actions of medical staff. The guide wire 3 may comprise an inner portion and an outer portion, wherein the outer portion may be formed by winding a stainless steel wire of good quality around a spring rotating bed, and the inner portion may be a hard and straight wire core accommodated in the outer portion.
Alternatively, the distal end 304 of the guide wire 3 may be a J-shaped safety guide wire, where the guide wire 3 includes two ends, and the distal end 304 of the movable guide wire is bent in a J shape, so that if the distal end of the guide wire encounters a bending deformation to form a blood vessel during intubation, the front end of the guide wire will not be fixed on the wall of the blood vessel, thereby effectively preventing damage to the blood vessel.
Alternatively, the proximal guide wire end 301 and the proximal catheter end 101 may be fixed in position, and may be spaced apart on the system mount, i.e., 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, and the guide wire is bent and can be moved orderly, thereby ensuring the rapidness, the accuracy and the convenience of interventional operation.
For the specific configuration of the rapid exchange balloon system, in one embodiment, the guidewire proximal end 301 is cylindrical and the guidewire axis Z1 of the guidewire proximal end 301 is non-coaxially disposed with the conduit axis Z2 of the catheter proximal end 101. As shown in fig. 1 and 2, it can be understood that, for the catheter proximal end 101 and the guide wire proximal end 301 which are fixed in position are not on the same axis, as shown in fig. 2, the guide wire 3 can be in a bending arrangement and always keep a loose state, so that the orderly arrangement of the guide wire 3 can be ensured at the initial stage of the system, and the position of the guide wire proximal end 301 does not need to be adjusted in a fit manner when the guide wire distal end 304 moves, thereby effectively ensuring the movement requirement of the guide wire. Specifically, the rotation of the proximal end 301 of the guide wire can be effectively transmitted to the distal end 304 of the guide wire to adjust the deflection direction of the distal end 304 of the guide wire, and smooth movement of the distal end 304 of the guide wire can be realized by movement of the distal end 304 of the guide wire, and the rotation and movement are overlapped on the distal end 304 of the guide wire to accurately duplicate the operation of medical staff.
Further, with respect to the positional relationship of the guidewire proximal end 301 to the catheter proximal end 101, in one embodiment, the guidewire proximal end 301 is spaced parallel to the catheter proximal end 101. As shown in fig. 2, it can be understood that the guide wire axis Z1 and the pipe axis Z2 are arranged in parallel, which can improve the compactness of the system.
Still further, in one embodiment, the guidewire 3 further includes a guidewire attachment segment connected to the proximal guidewire end 301 and the distal guidewire end 304, the guidewire attachment segment being U-shaped and including a guidewire turning front 302 and a guidewire turning back 303 parallel to each other and an arcuate connection connected between the guidewire turning front 302 and the guidewire turning back 303. As shown in fig. 2, the guide wire connecting section between the guide wire proximal end 301 and the catheter proximal end 101 is in a U-shaped structure, the guide wire steering front portion 302 and the guide wire steering rear portion 303 can be structurally limited by external components of the system, and the distance between the guide wire steering front portion 302 and the guide wire steering rear portion 303 is always the same as the distance between the guide wire axis Z1 and the pipeline axis Z2, so that the orderly arrangement of the guide wires 3 is ensured, and the structural compactness of the guide wires 3 is improved. For the arc-shaped connecting part, the radian is not easy to be too large, wherein the distance between the guide wire axis Z1 and the pipeline axis Z2 is 5 cm at minimum, so that the bending angle of the guide wire 3 is prevented from being too large, the orderly movement of the guide wire 3 is ensured, and the operation difficulty is reduced.
For other specific configurations of the rapid exchange balloon system, in one embodiment, the rapid exchange balloon system further comprises a housing 100 for mounting the catheter 1, the rapid exchange balloon catheter 2, and the guidewire 3, and the housing 100 may be a plate-like member having a planar structure as shown in fig. 1 and 3, thus facilitating processing.
