Problems solved by technology

The disadvantage of the existing technology is that when the contrast agent solution is injected, the gas originally present in the balloon catheter is difficult to be discharged, causing the gas doped with the contrast agent solution to enter the balloon together, resulting in residual gas in the balloon, and remaining in the catheter. The gas in the balloon will affect the imaging effect and compression effect of the balloon during expansion

Abstract

The invention relates to the technical field of medical instruments, in particular to a balloon dilatation device and a using method thereof. The balloon dilatation device comprises a connector assembly, a catheter assembly and a balloon. The connector assembly comprises a first Luer connector and a second Luer connector. The catheter assembly comprises a catheter and a liner tube arranged in the catheter, the near end of the catheter is connected with the first Luer taper, the far end of the catheter is closed, the near end of the liner tube is connected with the second Luer taper, and the far end of the liner tube extends towards the far end of the catheter; the balloon is arranged on the catheter. By arranging the liner tube which is detachably connected in the catheter, a contrast agent solution can be guided into the catheter through the liner tube before an operation, and meanwhile, redundant air in the catheter is discharged from the first Luer taper, so that it is guaranteed that the contrast agent solution can be guided into the catheter through the liner tube during the operation; the balloon can be filled with the contrast agent solution in the catheter through pressurization of an injector which does not contain the contrast agent solution, residual gas in the balloon is avoided, and therefore it is guaranteed that the balloon achieves the best developing effect and compression effect in the expansion process.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a balloon expansion device and a method for using the same. Background technique [0002] The trigeminal nerve is a mixed nerve. It is the fifth pair of cranial nerves and the largest nerve in the face. It contains two fibers of general somatosensory and special visceral motor. It controls the sensation of the face, mouth, and nasal cavity and the movement of the masticatory muscles, and transmits sensory information from the head to the brain. The trigeminal nerve is formed by the confluence of the ophthalmic branch (first branch), maxillary branch (second branch) and mandibular branch (third branch). The muscles of mastication contract. Trigeminal neuralgia is short-lived, recurrent paroxysmal severe pain in the facial trigeminal nerve distribution area, also known as painful twitching. [0003] Percutaneous trigeminal nerve semilunar ganglion balloon compression for...
