Ultrasound-visible tearable, rapid-exchange and adjustable bending sheath tube

Abstract

The invention discloses an ultrasound visible tearable rapid exchange adjustable bending sheathing canal, the outer wall of a sheathing canal main tube (1) of the adjustable bending sheathing canal is provided with an indwelling catheter channel (5) used for constraining an indwelling catheter and / or a puncture needle, and the indwelling catheter channel (5) is provided with an easy-to-tear channel (53); the easy-to-tear channel (53) is arranged at the head end of the adjustable bending sheathing canal, so that the indwelling catheter channel (5) is torn by the easy-to-tear channel (53) before the adjustable bending sheathing canal retreats, the indwelling catheter and / or the puncture needle bound in the easy-to-tear channel (53) are / is indwelled, and the adjustable bending sheathing canal retreats out of the body of a patient. The positioning piece (2) can be clearly developed under ultrasound, so that accurate positioning of the head end of the adjustable bent sheathing canal is achieved, accurate conveying of an indwelling catheter and a puncture needle penetrating through the indwelling catheter is achieved, a specific medical instrument can also be assisted to enter the body of a patient through the internal jugular vein and extend to a target position under the guidance of ultrasound, and the medical instrument can be accurately conveyed to the patient through the internal jugular vein. And performing intracardiac diagnosis and treatment operation.

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 cardiac interventional diagnosis and treatment, the catheter generally cannot reach the left atrium directly through the percutaneous approach, but reaches the right atrium antegradely. The catheter is guided by an adjustable curved sheath, 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 interatrial septum is the femoral vein, and 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 patient needs to lie on the bed and immobilize with his lower limbs extended. Prolonged bed rest and limb immobilization will not only bring p...

Problems solved by technology

[0004] Furthermore, the current interventional diagnosis and treatment are all performed under X-ray imaging, which not only requires a special operating environment, but cannot achieve bedside operation, but also causes radiation radiation to the operating physician and the patient.
