Abstract

The invention provides a dilator which comprises a rod body and a controller, and one end of the rod body is connected with the controller; the rod body is provided with a first cavity and a second cavity, the first cavity is communicated with the two ends of the rod body, and the second cavity is communicated with the two ends of the rod body; a guide wire passes through the first cavity, and a bending control wire is arranged in the second cavity; a first inlet communicated with the first cavity is formed in the end, away from the rod body, of the controller, a second inlet communicated with the second cavity is further formed in the end, away from the rod body, of the controller, and a first outlet communicated with the first cavity is formed in the end, away from the controller, of the rod body; one end of the bending control wire is connected with the controller, and the other end of the bending control wire is connected with the end, away from the controller, of the rod body through the second cavity. The controller is used for controlling stretching and retracting of the bending control wire. The second cavity and the bending control wire are arranged on the rod body, the rod body can be controlled to be actively bent through the controller, and the risk of puncturing the blood vessel is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dilator. Background technique [0002] As the population ages, the number of patients with structural heart disease is also increasing. In addition to structural heart disease, patients are usually accompanied by some vascular diseases, and blood vessels need to be dilated to treat the disease. In the prior art, blood vessels are mainly dilated by dilators. However, the dilator in the prior art cannot adjust the curvature at the distal end, mainly by adapting to the curvature of the inner wall of the blood vessel. Since the blood vessels of patients are more fragile than healthy people, there is a greater risk of puncturing the blood vessels due to the excessive hardness of the dilator. Not conducive to the treatment of patients. [0003] It can be seen that there is a problem that the dilator has a relatively high risk of puncturing the blood vessel in the related a...
