Handheld multi-degree-of-freedom controllable interventional guide wire and interventional device

Abstract

The invention discloses a handheld multi-degree-of-freedom controllable interventional guide wire and an interventional device. The interventional device comprises a handle shell, a control module, abutton, a bearing, the multi-degree-of-freedom controllable interventional guide wire, a rigid sleeve, a driven wheel, a driving wheel, a driving motor, a separation seat, transition wheels, a separation wheel, a wire, a battery and a plug. The multi-degree-of-freedom controllable interventional guide wire comprises a soft sleeve, a hydrophilic layer and a head end, wherein the hydrophilic layer is positioned on the outer layer of the sleeve; the whole guide wire can be divided into an active bending section and a non-active bending section, and a spring is embedded in a hydrophilic layer of the active bending section and used for providing recovery rigidity of bending of the guide wire; and the guide wire further comprises a front-end torsion shaft, a front-end limiting ball, a front-endlimiting plate, a front-end torsion rope, a middle-section torsion rope, a middle-section limiting plate and a middle-section torsion shaft which are arranged in the sleeve. According to the invention, the manipulation of a surgeon can be accurately reproduced, and the surgeon can be assisted to complete a diagnosis and treatment task for a patient more efficiently and safely.

Description

technical field [0001] The invention discloses a hand-held multi-degree-of-freedom controllable intervention guide wire and an intervention device, which belong to the field of medical equipment, and in particular relate to a multi-degree-of-freedom controllable guide wire for vascular interventional surgery. Background technique [0002] As an important branch of contemporary minimally invasive surgery, minimally invasive interventional surgery is a product that emerges as the times require in the context of aging population in today's society. Cardiovascular and cerebrovascular diseases are one of several major diseases that seriously threaten human life, especially the lives of the elderly. According to research results, the number of deaths from cardiovascular and cerebrovascular diseases increases with the increase in the incidence of cardiovascular and cerebrovascular diseases every year. In the traditional minimally invasive interventional surgery, the doctor uses the...
