Detailed Description
To further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments, and for the convenience of understanding, "distal end" and "proximal end" herein refer to the end far away from and close to the operator, respectively.
The utility model relates to an intracranial venous thrombosis 6 extraction element, which comprises a conveying device 1, a guide wire 2 and a thrombus extraction component.
The delivery device 1 has a lumen 11, and the lumen 11 is formed with a side aperture 12.
The guide wire 2 is threaded through the side aperture 12 and out the distal end of the delivery device 1 for guiding the direction and passage of the thrombus within the patient's blood vessel 5.
The embolectomy component comprises an operation guide wire 3 and an embolectomy umbrella 4. The operation guide wire 3 is inserted into the proximal end of the lumen 11 and moves telescopically with the operation of the user at the distal end of the lumen 11. The thrombus-taking umbrella 4 is connected to the distal end of the operation guide wire 3 and movably inserted into the distal end of the thrombus 6 along with the telescopic movement of the operation guide wire 3.
Referring to fig. 1 to 2, in an embodiment of the present invention, the related components are implemented as follows:
the operation guide wire 3 is provided with a guide part 31 between the thrombus taking umbrella 4 and the far end of the operation guide wire 3 for guiding the thrombus taking umbrella 4 to pass through the thrombus 6 of a patient, and when a user operates, the guide part 31 is reserved to pierce the thrombus 6 before the thrombus taking umbrella 4, so that the thrombus taking umbrella 4 can conveniently pass through the thrombus 6, and the operation efficiency is improved.
Referring to fig. 3 to 7, for the use process of the present invention, the specific steps are as follows:
referring now to fig. 3, a guide wire 2 is threaded into the intracranial venous vessel 5 of the patient and through the thrombus 6 to reach the distal end of the thrombus 6.
② referring to fig. 4, the delivery device 1 is guided into the intracranial venous vessel 5 through the guide wire 2.
