Embodiment

[0041] refer to Figure 1-Figure 4 As shown, the present invention provides a controllable bending dilator, which includes a vertically arranged dilator tube 1 , a bending control handle 2 and a bending control wire 3 . Among them, the dilator tube 1 is provided with a small tube wall cavity 9, which is arranged along the length direction of the dilator, and both ends of the tube wall small cavity 9 pass through the tube wall of the dilator tube 1 to accommodate The bending control wire 3 and the bending control handle 2 are used to control the bending shape of the dilator. The bending control handle 2 is rotated and set in the dilator. 3. One end passes through the other end from one end of the tube wall small cavity 9, and the other end is connected to the bend control handle 2.

[0042] When using the dilator, the bending control handle 2 is rotated, and the bending control wire 3 is driven to move when the bending control handle 2 is rotating, so as to control the differe...

Abstract

The invention relates to a bending-controllable expander. The bending-controllable expander comprises an expander tube, a bending-control handle and a bending-control wire; the expander tube is provided with a tube wall small cavity; the tube wall small cavity is arranged in the length direction of an expander, and the two ends of the tube wall small cavity penetrate through the tube wall of the expander tube; the bending-control handle is used for controlling the bending shape of the expander, and the bending-control handle is rotationally arranged in the expander; the bending-control wire is used for changing the bending shape of the far end of the expander tube; and one end of the bending-control wire penetrates through the other end from one end of the tube wall small cavity, and the other end of the bending-control wire is connected to the bending-control handle. The bending-controllable expander has the characteristics of adapting to individual differences of human bodies and physiological anatomy of different parts of the human bodies, and can be directly adjusted to the most ideal target position conveniently during an operation, so that the operation process is more autonomous and controllable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a controllable bending dilator. Background technique [0002] Cardiac arrhythmia is a disease that seriously affects the health and quality of life of patients. Atrial fibrillation (AF) is the most common arrhythmia disease. The incidence rate of the population is about 1-2%. It has a high disability rate and mortality rate. Interventional therapy It is an important treatment for atrial fibrillation and other arrhythmias. Atrial septal puncture is a widely used method combined with multiple percutaneous catheter operations for arrhythmias of left atrial origin, such as atrial fibrillation, atrioventricular reentrant tachycardia caused by left atrioventricular bypass, and arrhythmias of left ventricular origin. In medical technology, in atrial septal puncture surgery, dilators are required. The dilator plays a role in establishing pathways and supports in atrial septal pu...
