Abstract

The invention discloses an ultrasonic joint probe used in the blood vessel. The ultrasonic joint probe comprises a probe body extending into the blood vessel and a catheter communicated with the probe body and extending out of the body, wherein an ultrasonic detection head and a high-energy focusing head are arranged in the probe body, a main tube casing communicated with the probe body is arranged outside the probe body, three air bags are arranged on the main tube casing, the catheter is provided with a middle interlayer, and a channel for a wire to pass through is formed in the catheter. The middle interlayer of the catheter is used for inflating the air bags. The ultrasonic joint probe can be accurately focused on the target spot nerve.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an ultrasonic combined probe used in blood vessels. Background technique [0002] High-intensity focused ultrasound (HIFU) is a kind of energy that can be precisely focused and non-contact damage. Through intravascular intervention, it can be sent to the position of the target nerve to release heat energy for nerve damage treatment. For the treatment of cardiac pre-excitation syndrome and atrial fibrillation. At present, the independent balloon ultrasound probe cannot accurately determine the specific position of the target nerve in the blood vessel, and cannot accurately locate the focal point of the probe on the target nerve trunk or ganglion. In addition, because the balloon of the balloon ultrasound probe is a cylindrical or ellipsoid-like structure, it only has two modes of fixation in the blood vessel, floating and fixed, and the balloon probe cannot adjust the distance to t...
