Problems solved by technology

[0007] According to the technical solution provided by the embodiment of the present application, at least two inflow ends are provided through the first connector, and each inflow end is connected with a self-locking syringe, and the adhesive and sugar water are sucked into different syringes respectively. When the catheter is flushed, there is no need to separate the syringe from the catheter, which reduces the difficulty of operation and saves operation time. At the same time, the catheter inserted into the vein is positioned by the light positioning device, which is more convenient to operate and can solve the inconvenience of the prior art. question

Abstract

The invention discloses an intracavity closing system for varicose veins of lower limbs. The system comprises a self-locking injector, a first connecting piece and a catheter which are connected in sequence; the self-locking injector is provided with a first accommodating cavity used for containing a to-be-injected substance. The first connecting piece is provided with a second accommodating cavity; the catheter is provided with a third accommodating cavity; the third accommodating cavity at least comprises a first sub accommodating cavity and a second sub accommodating cavity which are independent of each other; the first sub- accommodating cavity and the second sub- accommodating cavity penetrate through the catheter in the length direction of the catheter. The first accommodating cavity, the second accommodating cavity and the second sub- accommodating cavity are communicated, the second accommodating cavity is provided with an outflow end and at least two inflow ends, each inflow end is connected with one self-locking injector in a sealed mode, and the outflow end is connected with the catheter in a sealed mode. And the catheter extending into the vein is positioned through thelight positioning device, so that the operation is more convenient.

Description

technical field [0001] The present invention generally relates to the field of medical devices, in particular to the field of medicament propulsion devices, and in particular to an intracavity closure system for varicose veins of the lower extremities. Background technique [0002] Varicose veins of the lower extremities is one of the most common surgical diseases, and the incidence rate in Western countries can reach 30%. The incidence of varicose veins of lower extremities increases with age, which seriously affects people's quality of life and increases the economic burden of society. Non-surgical therapy is less effective and prone to recurrence. The traditional operation is high ligation and stripping. This method is completely treated and has been widely used. However, the surgical damage is large, the scars are many, and the appearance is affected, and the recurrence rate is high. Foam sclerosing agent treatment is incomplete, especially for large varicose veins, th...
