Problems solved by technology

The disadvantage of the prior art is that the filter hook can only be captured through a capture ring, which can only be completed through multiple captures through the experience of the doctor. The capture speed and accuracy are low, and it takes a long time, causing the patient's unwell

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention in specific situations.

[0032] Such as image 3 As shown, a double-leaf vascular foreign body catcher of the present invention includes a double-leaf catcher, an outer sleeve 2, a control push rod 3 and a catch ring 4; the control push rod 3 wraps the ...

Abstract

The invention discloses a double-blade vascular foreign body grabbing device, which comprises an outer sleeve, a control push rod and two grabbing rings. The control push rod is wrapped with the outersleeve; one end of the control push rod extends out of the outer sleeve to be connected with the grabbing rings; and the other end of the control push rod extends out of the tail of the outer sleeve.The end of the push rod is connected with the two grabbing rings, different from a commonly-used single-ring grabbing device and three-blade grabbing device, when a vena cava filter or other foreignbodies are grabbed, one grabbing point is added equivalently, a spatial difference exists between the two grabbing points, thus the accurate rate and grabbing speed of doctors for grabbing the vena cava filter or the other foreign bodies are increased, the discomfort of patients is reduced, and the X-ray radiation dose for the doctors and the patients is decreased.

Description

technical field [0001] The invention relates to a medical device for interventional treatment, in particular to a double-leaf vascular foreign body catcher. Background technique [0002] Thrombosis is a disease caused by abnormal blood clots formed in blood vessels in circulating blood during human survival. Thrombosis occurs for three reasons: damaged blood vessels, blood changes, and blood stasis. Thrombosis is a group of complications caused by many different diseases with different causes. Due to the differences in various underlying diseases and the different sites of thromboembolism, the clinical manifestations of thrombosis are also different. [0003] During the treatment of thrombosis, if the intravascular thrombus enters the lungs through the inferior vena cava and causes pulmonary embolism, causing the patient to suffocate to death, in order to prevent pulmonary embolism such as figure 2 As shown, during the treatment period, a vena cava filter 7 is inserted in...
