Cerebral nerve vessel thrombus taking-out device

Abstract

The invention belongs to the technical field of cerebral nerve and blood vessel thrombus extraction, and specifically relates to a cerebral nerve vessel thrombus taking-out device that comprises an outer protective tube, a middle adjusting guide wire and a thrombus extractor body. The outer wall of the middle adjusting guide wire is sleeved with the outer protection tube; the two ends of the middle adjusting guide wire extend to the two sides of the outer protection tube; one end of the middle adjusting guide wire is connected with a thrombus extractor; the end, away from the thrombus extractor, of the outer protection tube is connected with an adjusting assembly, the thrombus extractor comprises a movable connecting base and a fixed connecting base, through the arrangement of the adjusting assembly, the relative position between the outer protection tube and the middle adjusting guide wire can be adjusted conveniently from the outside, and therefore the thrombus extractor can be adjusted to be unfolded and folded, and operation is convenient. The thrombus extractor enables the thrombus extraction wire to be unfolded and folded through the effect of adjusting the position between the movable connecting base and the fixed connecting base, and therefore the adjusting effect of overall expansion or contraction of the thrombus extractor is achieved.

Description

technical field [0001] The invention relates to the technical field of cerebral nerve and blood vessel thrombus removal, in particular to a device for removing cerebral nerve and blood vessel thrombus. Background technique [0002] Cranial nerves are also called "cranial nerves". It is a pair of left and right nerves that originate from the brain and belongs to the peripheral nervous system. There are 12 pairs of human cranial nerves: I olfactory nerve, II optic nerve, III oculomotor nerve, IV trochlear nerve, V trigeminal nerve, VI abducens nerve, VII facial nerve, VIII auditory nerve, IX glossopharyngeal nerve, X vagus nerve, and XI accessory nerve. Nerve, Ⅻhypoglossal nerve. They are mainly distributed in the head and face, and the vagus nerve also distributes to the visceral organs of the chest and abdomen. Among the 12 pairs of cranial nerves, pairs I, II, and VIII are sensory nerves; pairs III, IV, VI, XI, and XII are motor nerves; pairs V, VII, IX, and X are mixed ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a device for removing thrombus from cerebral nerve vessels to solve the problem that the existing thrombus retriever proposed in the background technology is inconvenient to operate during use, and it is not easy to adjust the expansion and contraction of the thrombus retriever, and After adjustment, the thrombus retriever is prone to retraction when it receives force, which affects the use effect
