Embodiment approach

[0036] Such as figure 1 -3 shows a specific implementation of the thrombus removal device provided in this embodiment, including: a recovery tube 1 and a medicine delivery tube 2 .

[0037] A pair of thrombus recovery openings 4 are provided on the side wall of the recovery tube 1 along the front-back direction. The above-mentioned front-back direction is the direction in which the recovery tube 1 advances and retreats in the blood vessel. There is a double circulation forming hole 3, and a Y-shaped channel is arranged in the double circulation forming hole 3, the first outlet of the Y-shaped channel faces the inner wall of the blood vessel and is biased forward, and the second outlet of the Y-shaped channel faces the inner wall of the blood vessel and is biased Second exit at the rear. Three pairs of double circulation forming holes 3 are arranged along the circumferential direction of the tube wall of the recovery tube 1, and three pairs of thrombus recovery ports 4 are set...

Abstract

The invention provides a thrombus removing device, and belongs to the technical field of medical care apparatuses. The thrombus removing device comprises a recovering pipe and a medicine transportingpipe, wherein at least two thrombus recovering openings are formed in the side wall of the recovering pipe in the front-and-rear direction; one or more dual-circulation forming holes are formed in themiddle of each thrombus recovering opening, and each dual-circulation forming hole is provided with a first outlet in the direction facing the inner wall of a blood vessel and deviates the front part; each dual-circulation forming hole is also provided with a second outlet in the direction facing the inner wall of a blood vessel and deviates the rear part; the medicine transporting pipe is arranged in the recovering pipe, and is provided with one or more efflux holes; and each efflux hole faces the inlet of the corresponding dual-circulation forming hole. According to the thrombus removing device provided by the invention, after being jetted from the efflux holes to the dual-circulation forming holes, the liquid medicine is divided into two liquid medicine flows of which the directions are different; the two liquid medicine flows can remove thrombus on the blood vessel pipe in the front direction and in the rear direction, the impact area of the liquid medicine is enlarged, the advancing and withdrawing range of the recovering pipe in the blood vessel is reduced, and the thrombus removing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thrombus removal device. Background technique [0002] Mechanical thrombectomy is a treatment for blood clots in which a thrombectomy device is delivered to the site of deep vein thrombosis and mechanically removed from the clot. Its curative effect is short and the therapeutic effect is excellent. It is currently the most advanced and effective peripheral arterial and venous thrombosis volume reduction technology. [0003] Chinese patent document CN110049735A discloses a catheter for thrombus removal, including a fluid pulse generator, an outflow hole, an inflow hole and a high-pressure tube. The high-pressure tube is provided with a spray hole, and the fluid pulse generator is used to control the flow of the liquid medicine. After the ejection hole is ejected, the thrombus removal catheter is ejected from the outflow hole to return to the thrombus removal catheter fr...
