Abstract

The invention discloses a guide plug filter. An outer sleeve is sheathed on a catheter, and the outer sleeve includes: a first sleeve and a second sleeve, and a plurality of bendable sleeves are passed between the first sleeve and the second sleeve. The filter strip is connected, the first sleeve is fixedly sleeved on the catheter, the second sleeve is slidably sleeved on the catheter, and the second sleeve is facing the first sleeve during the thrombolytic operation Sliding can stretch multiple filter strips to form a curved arc, and the dissolved thrombus can be blocked by multiple filter strips to prevent thrombus from backflow, which solves the problem of being dissolved during thrombolytic surgery in the prior art. Thrombosis is prone to reflux and affects the technical problems of normal operation.

Description

Technical field [0001] The invention relates to the field of medical appliances, and in particular to a guide plug filter. Background technique [0002] Blood thrombolysis is currently a frequent operation in hospitals, and the thrombus dissolved in the process of thrombolysis often returns to affect the normal operation of the operation. [0003] Aiming at the technical problem that the thrombus dissolved during the thrombolytic operation in the prior art is prone to reflux and affects the normal operation of the operation, no effective solution has been proposed. Summary of the invention [0004] The embodiment of the present invention provides a guide plug filter to at least solve the technical problem that the thrombus dissolved in the thrombolytic surgery process in the prior art is prone to reflux and affects the normal operation of the surgery. [0005] According to an embodiment of the present invention, there is provided a guide plug filter, comprising: a catheter; an outer ...
