[0002] Thrombi are small pieces of blood formed on the surface of the peeling or repairing of the inner surface of the cardiovascular system. In the variable fluid-dependent type, thrombi are composed of insoluble fibrin, deposited platelets, accumulated white blood cells and trapped red blood cells; the main characteristics of common thrombosis patients in clinical practice are familial inheritance, recurrent attacks, severe symptoms, abnormal thrombosis site, and young onset time.

[0003] In the treatment of blood clots, the blood clots in the blood vessels are mainly extracted through catheters. When the blood clots in the blood vessels are large in diameter and hard in texture, the movement space in the blood vessels is limited, which makes it difficult for the catheter to extract them out efficiently. In addition, during the insertion of the catheter, the blood clots are easily pushed to move in the blood vessels, posing a great safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Example:

[0029] Reference Figure 1-Figure 5 This embodiment discloses a thrombus removal sheath tube device assembly, comprising a flexible long tube 1, and also comprising: a flexible thin rod 2, fixedly connected to one end of the long tube 1, wherein the thin rod 2 is eccentrically arranged at the axial end of the long tube 1, and the thin rod 2 is parallel to the axis of the long tube 1, and the end of the thin rod 2 is provided with an arc chamfer to reduce the resistance of the thin rod 2;

[0030] The first C-shaped airbag 3 and the second C-shaped airbag 4 which are elastic are both fixedly connected to the outer wall of the thin rod 2 , wherein the other end of the long tube 1 is provided with an adjusting portion for supplying air to the first C-shaped airbag 3 and the second C-shaped airbag 4 .

[0031] Specifically, when in use, the thin rod 2 and the long tube 1 are inserted into the blood vessel, and the thin rod 2 is passed through the thrombus along the inner wall of the blood vessel. During the passing, the side with thin thrombus or no thrombus is selected as much as possible to prevent the thrombus from being pushed; at the same time, the thrombus is located between the first C-shaped balloon 3 and the second C-shaped balloon 4, and then the first C-shaped balloon 3 and the second C-shaped balloon 4 are expanded through the adjustment part, so as to expand the diameter of the blood vessel, and the activity space at the thrombus will be increased, which can facilitate the subsequent removal of larger diameter thrombus, which may include the action of breaking the thrombus; during the removal, the catheter can be passed through the circular hole formed by the long tube 1 and the first C-shaped balloon 3 to facilitate the catheter to extract the thrombus.

[0032] The adjusting part in the thrombus removal sheath tube equipment assembly includes a flexible thin tube 5 fixedly connected to the axial end of the long tube 1, and the movable end of the thin tube 5 is fixedly connected to the long tube 6 connected thereto; wherein, the other end of the thin tube 5 is connected to the first C-shaped airbag 3 and the second C-shaped airbag 4, and a piston 9 is slidably installed in the long tube 6, and the piston 9 can only slide linearly along the axis of the long tube 6; a pushing part is provided on the port of the long tube 6 to push the piston 9 to slide linearly along the inner wall of the long tube 6, and the pushing part includes a support plate 7 fixedly connected to the port of the long tube 6, and an internal threaded tube 10 extending into the long tube 6 is rotatably connected to the support plate 7; wherein, the internal threaded tube 10 is internally threadedly connected to a threaded rod 8, the piston 9 is fixedly connected to one end of the threaded rod 8, and the end of the internal threaded tube 10 away from the piston 9 is fixedly connected to a turning handle 11, and the outer wall of the turning handle 11 is provided with anti-slip patterns to improve the hand feel.

[0033] Specifically, when it is necessary to enlarge the diameter of the blood vessel, turn the handle 11, the handle 11 will drive the internal threaded tube 10 to rotate, and the internal threaded tube 10 will drive the piston 9 to slide toward the capillary 5 through the threaded rod 8, and the gas in the long tube 6 will be squeezed by the piston 9; and transported to the first C-shaped airbag 3 and the second C-shaped airbag 4 through the capillary 5, the first C-shaped airbag 3 and the second C-shaped airbag 4 will expand, thereby enlarging the diameter of the blood vessel. When it is necessary to shrink the first C-shaped airbag 3 and the second C-shaped airbag 4, reverse the handle 11.

[0034] Specifically, the outer wall of the thin rod 2 is slidably sleeved with a sleeve 12, and a flexible pull rod 13 that passes through the long tube 1 is fixedly connected to the sleeve 12. The flexible pull rod 13 is tightly attached to the inner wall of the long tube 1, and the sleeve 12 is wrapped around the outer walls of the first C-shaped airbag 3 and the second C-shaped airbag 4.

[0035] Before extracting the thrombus, the sleeve 12 can wrap the first C-shaped airbag 3 and the second C-shaped airbag 4, so when the thin rod 2 is inserted into the blood vessel, the sleeve 12 can reduce the resistance given to the thrombus by the first C-shaped airbag 3 and the second C-shaped airbag 4, and prevent the thrombus from being deflected by the first C-shaped airbag 3 and the second C-shaped airbag 4, thereby improving the safety of the entire operation. After the positioning is completed, the flexible pull rod 13 is pulled so that the flexible pull rod 13 pulls the sleeve 12 away from the first C-shaped airbag 3 and the second C-shaped airbag 4, and the first C-shaped airbag 3 and the second C-shaped airbag 4 can be exposed in the blood vessel, and the first C-shaped airbag 3 and the second C-shaped airbag 4 can be inflated at this time. After removing the thrombus, the flexible pull rod 13 can also be pushed so that the sleeve 12 wraps the first C-shaped airbag 3 and the second C-shaped airbag 4 again to reduce the resistance when the thin rod 2 is extracted.

[0036] Specifically, a pull ring 14 is fixedly connected to the end of the flexible pull rod 13 , and the flexible pull rod 13 can be pulled more conveniently through the pull ring 14 .

[0037] Specifically, a damping protrusion 16 is fixedly connected to the outer wall of the thin rod 2. When the sleeve 12 moves away from the first C-shaped airbag 3 and the second C-shaped airbag 4, the damping protrusion 16 presses against the inner wall of the sleeve 12. After the sleeve 12 is moved, the damping protrusion 16 can increase the resistance between the sleeve 12 and the outer wall of the thin rod 2 to prevent the sleeve 12 from moving accidentally, thereby improving safety.

[0038] An inclined surface 15 is provided on one end of the long tube 1 close to the thin rod 2. When the thin rod 2 and the long tube 1 are inserted into a blood vessel, the inclined surface 15 can better transition the long tube 1 to reduce damage to the blood vessel caused by the end of the long tube 1.

[0039] Specifically, the cross-section of the axial end of the thin rod 2 is in an arc shape, and the inner and outer walls of the thin rod 2 are respectively arranged coplanar with the inner and outer walls of the long tube 1, so that the thin rod 2 can fit more closely to the blood vessel.

[0040] When used, the thrombus removal sheath device assembly can facilitate the subsequent removal of thrombi with larger diameters. During the removal period, it also has a structural function that facilitates the extraction of thrombi by a catheter, so it is safer and has greater practical value.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
