Description

Fixing device for traction wire of esophageal stent

Technical Field

The utility model relates to the field of medical equipment and relevant technology, especially, relate to an esophageal stent pull wire fixing device.

Background

In clinic, patients with benign and malignant esophageal stenosis often need to place an esophageal stent to open the stenosis part. Because the esophageal stent is easy to fall off due to the peristalsis and the gravity action of the esophagus, a traction wire is usually connected with the stent, led out from the nostril and then fixed on the face or the ear of a patient. Due to the fixed position, the patient can pull the traction wire when smiling, chewing or speaking, so that the traction wire is not uniform in tightness, the support is still easy to shift or fall off, the good fixing effect is not achieved, and the attractiveness of the patient is also influenced.

SUMMERY OF THE UTILITY MODEL

The present invention is provided to solve one or more deficiencies in the related art. According to the technical scheme of the utility model, can solve current pull wire and can't fix, cause the support to shift or drop the scheduling problem.

In order to solve the problem, the utility model provides an esophageal stent pull wire fixing device, including mirror holder, first fixed line and the fixed line of second, the mirror holder includes first picture frame, second picture frame and two mirror legs, first picture frame has the first limit on upper portion and the second limit of medial part, the second picture frame includes the third limit on upper portion and the fourth edge of medial part, first limit with the third limit has respectively along first limit with first recess and the second recess that the third limit extends, the second limit has along its third recess that extends or the fourth limit has along its fourth recess that extends, the upper left corner, the upper right corner at the mirror holder are fixed respectively to the one end of first fixed line and the fixed line of second.

Furthermore, the left and right upper corners of the mirror bracket are respectively fixed with a screw buckle, and one end of the first fixing line and one end of the second fixing line are respectively fixed on the left and right upper corners of the mirror bracket around the screw buckles.

And the other ends of the first fixing wire and the second fixing wire respectively extend along the first groove and the second groove, then enter the third groove or the fourth groove and are respectively fixedly connected with the traction wire.

Compared with the prior art, the utility model discloses a but not limited to following beneficial effect:

After being led out from nostrils, the traction wires on the esophageal stent are connected with two fixing wires, the two fixing wires are separated from each other after reaching the upper edge of the picture frame through the groove in the picture frame, and then reach the screw buckle at the left (right) upper corner through the groove on the upper edge of the picture frame, and the fixing wires are fixed on the screw buckle in a surrounding way. The length of the fixed wire can be adjusted through the rotation of the screw fastener, so that the tightness of the traction wire is adjusted, meanwhile, the traction wire is firmly fixed through multiple points of the head, the ears and the bridge of the nose, so that the stability of the esophageal stent is ensured, and the probability of falling and shifting of the stent is reduced. Meanwhile, the traction wire is detachably connected with the fixing device, so that the fixing device can be flexibly supplied to a patient to use, and the device is safe, convenient, economical and practical, and has great improvement on safety, attractiveness and comfort.
