Embodiment Construction

[0026] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings. In addition, it should be noted that the "proximal end" and "distal end" in the following embodiments are conventional names for equipment in the field, "proximal end" refers to the end close to the operating end, and "distal end" refers to the end far away from the operating end. end to end.

[0027] Such as Figure 1 to Figure 6 , this embodiment discloses a medical interventional suction catheter, which is used in interventional therapy to clean up calcified plaque or thrombus in blood vessels. Specifically, the suction catheter includes a tube body 1 and a push rod 2 , suction interface 6 and movable end 3. in figure 1 The push rod 2 in is in the retracted state, figure 2 The push rod 2 in is in extended state.

[0028] Both ends o...

Abstract

The invention discloses a medical intervention type suction catheter, which comprises a catheter body, a push rod, a suction interface and a movable end, wherein the push rod can slide back and forth relative to the catheter body so as to make the free end of the push rod extend out of or retract into the catheter body, the movable end is connected with the free end of the push rod, a thrombus breaking device is arranged on the movable end, the head of the movable end is provided with a tip structure, a guide wire cavity and a drainage cavity are formed in the push rod, a guide wire penetrates through the guide wire cavity, a through hole opposite to the guide wire cavity is formed in the movable end, a plurality of drainage holes communicated with the drainage cavity are formed in the outer wall of the push rod, and the suction interface is arranged at the near end of the push rod and communicated with the drainage cavity. According to the invention, by means of the suction catheter with the structure, in the operation process of an interventional operation, plaques or thrombus can be broken, and the broken plaques or thrombus can be sucked out in time, so that blockage of the large plaques or thrombus to the catheter in the suction process is reduced, and the suction catheter is more convenient to use, saves time and is more efficient.

Description

technical field [0001] The invention relates to the technical field of interventional medical appliances, in particular to a medical interventional suction catheter. Background technique [0002] Severe calcification on the periphery or on the surface of other inner walls of blood vessels, resulting in narrowed blood flow in blood vessels, causing thrombosis, plaque rupture, or tissue necrosis. For this, the current clinical interventional treatment is generally first to reach the need for treatment through the guide wire The location of the lesion, and then put in the expansion balloon catheter to open the narrow diseased blood vessel, and then place the stent to achieve the purpose of treatment. However, when severely calcified lesions are encountered, it is difficult for the guidewire and balloon catheter assembly to pass through calcified lesions or thrombus plaques. In addition, when there are large thrombus plaques in blood vessels, it is easy to cause ischemia, leadi...
