Description

Visual lumen dilator

Technical Field

The utility model relates to the field of medical equipment, in particular to a visual lumen expander.

Background

In order to treat the disease such as the narrow or pathological changes of the human body lumen, a saccule type dilator or a dilation bougie is generally adopted to firstly dilate the affected part. The existing dilators are not sufficiently safe or must be able to display the dilated state with the aid of an X-ray device. For example, the conventional balloon-type dilator mainly comprises a balloon, a catheter communicated with the balloon and a radiopaque developing part, wherein a guide wire channel is arranged in the catheter, when the balloon-type dilator is used, the uninflated balloon-type dilator reaches an affected part through the guide wire, gas is filled into the balloon through the catheter, the balloon is inflated to extrude the two sides of the balloon and dilate a human body lumen, and in the process that the balloon-type dilator is guided through the guide wire, a device capable of emitting X rays is used for displaying the real-time position of the balloon-type dilator in the lumen. The dilating bougie mainly comprises a dilating bougie main body and a radiopaque developing part, wherein a guide wire channel is arranged in the dilating bougie main body, when the dilating bougie is used, the dilating bougie reaches and passes through an affected part through the guide wire, and in the process of passing through a cavity, the body cavity tube can be dilated because the outer diameter of the dilating bougie is larger than the inner size of a lesion cavity, and the real-time position of the dilating bougie in the cavity tube is displayed by a device capable of emitting X-rays. Although the balloon type dilator and the dilation bougie change the pain of a patient caused by the original surgical operation and simplify the operation, the traditional balloon type dilator cannot observe the condition of a tube cavity passing through the traditional balloon type dilator in real time, cannot confirm a dilation scheme in advance according to the actual condition, and can only dilate a target cavity according to the experience of a doctor; the expansion bougie only adopts ordinary development piece, through the equipment that can send X ray, shows the real-time position of expansion bougie in the chamber pipe, and the imaging effect is not significant, single product price is expensive, need disinfect the cleanness after every use, increases use cost, and need cooperate disposable seal wire to use, indirectly increases single operating cost. In addition, when a narrow part which cannot be reached by an endoscope is dilated using a balloon dilator or a dilation bougie, the narrow part and the dilated state cannot be observed in real time, and thus it is difficult to determine whether or not a postoperative complication occurs. Meanwhile, the long-term use of the X-ray emitting device can cause serious influence on the health of medical care personnel.
