The invention discloses an interventional medical instrument delivering
system. The
system comprises a
catheter with a
hemostasis valve of which an opening is adjustable, the
catheter comprises a
pipe fitting and a
hemostasis valve main body, and the near end of the
pipe fitting is connected with the far end of the
hemostasis valve main body; the
system further comprises a
silica gel ring and a
screw cap, the
screw cap is connected with the
hemostasis valve main body through a thread at the near end of the
hemostasis valve main body, and the size of an opening formed in the near end of the
hemostasis valve main body is adjusted by rotatably compressing or loosening the
silica gel ring through the thread; the side face of the hemostasis valve main body is provided with a side hole used for being connected with a hose and a three-way valve, and an injection
syringe can be connected to the hemostasis valve main body through the three-way valve to inject
medicine. According to the interventional medical instrument delivering system, adjusting operation on the opening of the hemostasis valve of the
catheter is easy and convenient, the condition that blood overflows and gas enters the body of a patient in the using process can be avoided, an operator can conveniently inject
medicine to the patient in case of need, therefore, the catheter
intervention treatment effect can be effectively improved, the
operation safety is improved, and the operation success rate is increased.
