Problems solved by technology

Prolonged bed rest and limb immobilization will not only bring potential thrombosis risk to patients, but also prone to adverse events such as limb numbness, pain, loss of appetite, abdominal distension, and urinary retention, as well as mental and psychological symptoms such as anxiety, depression, and irritability. question
Therefore, at present, atrial septal puncture is generally a transient operation, and the left atrial canal cannot be left in place. If a second diagnosis and treatment is required, a second puncture is required.

Abstract

The invention discloses an ultrasound-visible tearable rapid-exchange bending-adjustable sheathing canal, the head end of a sheathing canal main tube (1) of the sheathing canal is provided with an ultrasound-visible positioning piece (2), the tail end of the sheathing canal main tube (1) is provided with a bending-adjustable control handle (4), and the sheathing canal can enter the blood vessel of a patient through an internal jugular vein indwelling sheathing canal. And under ultrasonic guidance, the catheter extends to a specific position of the atrial septum along the vein to assist in atrial septum puncture.

Description

technical field [0001] The application belongs to the field of medical devices, and in particular relates to a tearable and quick-exchanging adjustable curved sheath visible under ultrasound. Background technique [0002] In cardiovascular interventional diagnosis and treatment, through the percutaneous approach, the catheter generally cannot directly reach the left atrium, but goes antegrade to the right atrium. A large number of doctors have explored the method of atrial septal puncture, so that the catheter can go antegrade to the right atrium and then pass through the atrial septum into the left atrium, so as to realize the inspection and treatment of the left heart system. [0003] At present, due to the problem of the puncture angle, the main approach for percutaneous puncture of the atrial septum is the femoral vein. The puncture point of the femoral vein approach is at the root of the thigh. If the left atrium tube is placed through the femoral vein approach, the pa...
