Background

Venous thrombosis is a common disease which endangers human health, most of the venous thrombosis happens to deep veins (femoral vein, popliteal vein, gastrocnemius intermyo-muscular vein and the like) of pelvic cavity and lower limbs, and the venous thrombosis is frequently seen in patients after delivery, fracture, trauma and operation, and has high morbidity. Repeated shedding of venous thrombi can cause pulmonary embolism and pulmonary infarction, both of which severely endanger the life of the patient. The treatment method of venous thrombosis mainly comprises the following three methods: drug therapy, surgical embolectomy, and filter implantation. The current common treatment for venous thrombosis is to place a "strainer," which is a venous filter, between the thrombogenic vein and the lung to effectively filter the thrombus and prevent it from entering the lung through blood flow.

However, since the filter is implanted to cause thrombus formation and the long-term implantation is likely to cause intimal hyperplasia covering and lose its value, the filter is recovered in a certain period. The current catcher for recovering the filter finds the filter recovery hook by the hand feeling of a doctor working for a long time, and the filter can move in the recovery process of the vein filter, so that the recovery process is longer, the recovery process is assisted by ray irradiation, and the human body can be seriously injured when being exposed to the ray for a long time.

Detailed Description

The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "top," "bottom," "inner," and the like refer to orientations or positional relationships based on those shown in the drawings, which are used for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, the direction of insertion of the catcher is the front end, and conversely, the rear end.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; either directly or indirectly through intervening media, either internally or in any combination thereof. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In one embodiment of the present invention, a filter recovery device is provided, as shown in fig. 1-3, comprising an outer tube 1, an inner tube 2, and a collapsible umbrella 3; one side of the inner pipe 2 is connected with a side pipe 4, and the side pipe 4 is communicated with the inner pipe 2; one end of the inner pipe 2, which is far away from the side pipe 4, is connected with a foldable umbrella 3; the outer surface of the outer tube 1 is provided with two handles 5 in a sliding manner, the two handles 5 are symmetrically arranged, and one end of one handle 5 is provided with an opening 6; the outer pipe 1 is provided with a section of corrugated pipe 7, the outer pipe 1 is sleeved outside the inner pipe 2, and the side pipe 4 extends out of the opening 6.
