Embodiment Construction
[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings and the embodiments of the present invention.
[0049] figure 1 It is a structural schematic diagram of the adjustable thrombus removal device of the present invention.
[0050] Such as figure 1 As shown, the adjustable thrombus removal device is used to remove the thrombus blocking the blood vessel by mechanical means to achieve the purpose of blood vessel recanalization and blood flow recovery. The adjustable thrombus removal device includes a main support 1 , an adjustable support 2 , a push tube 3 , a push wire 4 and a handle 5 . Wherein, the main bracket 1 , the adjustable bracket 2 , the push wire 4 and the handle 5 are connected in sequence, and the push wire 4 is connected to the handle through the push tube 3 .
[0051]Specifically: one end of the main bracket 1 is closed, the middle section of the main bracket 1 is movably connected in the through h...

The invention discloses an adjustable thrombus removal device and a manufacturing method thereof. The device comprises a main bracket (1), an adjustable bracket (2), a pushing tube (3), a pushing wire (4) and a handle (5); One end of the main bracket (1) is closed, the middle section of the main bracket (1) is flexibly connected with the adjustable bracket (2), and the other end of the adjustable bracket (2) is fixedly connected with the push tube (3), The other end of the push tube (3) is connected to the handle (5); the other end of the main bracket (1) is fixedly connected to the push wire (4), and the other end of the push wire (4) passes through the The push tube (3) is connected to the handle (5); the adjustable bracket (2) can move back and forth along the axial direction of the main bracket (1). With the present invention, the thrombus in the blood vessel can be taken out mechanically, and the thrombus can be partially locked by the adjustable bracket to prevent the thrombus from escaping.
Description
technical field [0001] The invention relates to medical device manufacturing technology, in particular to an adjustable thrombus removal device and a manufacturing method thereof. Background technique [0002] Stroke refers to a group of diseases that cause damage to brain tissue due to sudden rupture of blood vessels in the brain or blockage of blood vessels that prevent blood from flowing into the brain. [0003] At present, the number of deaths due to stroke in China every year has surpassed tumors and cardiovascular diseases, becoming the first cause of death. Treatment in the acute phase is extremely important for the prognosis of stroke patients. Evidence-based medicine has confirmed that intravenous thrombolysis with recombinant tissue plasminogen activator (r-TPA) within 4.5 hours of onset is the first choice for the treatment of acute ischemic stroke. However, patients who can arrive at the hospital within the time window and have indications for thrombolysis are ...
