More reliable hypotube fast switching and imbedding device

Abstract

The invention discloses a more reliable hypotube fast switching and imbedding device which comprises an outer tube. A tip tube is arranged at one end of the outer tube, a front handle is arranged at the other end of the outer tube, an inner tube is nested in the outer tube, a hypotube is nested in the inner tube, corresponding parts of the outer tube, corresponding parts of the inner tube and corresponding parts of the hypotube are provided with guide grooves, channels for allowing zebra guide wires to penetrate through are formed by extending from the guide grooves to the center of the tip tube, guide tubes with the diameter larger than that of the zebra guide wires are arranged in the channels, and one end of each guide tube stretches out of the corresponding guide groove. According to the more reliable hypotube fast switching and imbedding device, due to the fact that the dedicated guide tubes are used for guiding, it is guaranteed that the zebra guide wires can penetrate out of the inner tube and the outer tube thoroughly, and the demands of fast switching are met. Due to the fact that the hypotube is engraved by using lasers, the consistency and the stability of the hypotube can be controlled completely, and manufacturability is good. Meanwhile, according to using situations of imbedding devices at different positions, lasers can be adjusted for engraving patterns, and therefore the design requirements of the imbedding devices at different positions can be met easily. Meanwhile, the tail end of the more reliable hypotube fast switching and imbedding device supports a transfusion function.

Description

technical field [0001] The invention relates to a medical inserter device, in particular to a more reliable rapid exchange inserter for hypotubes. Background technique [0002] The quick-exchange biliary stent implanter can use short-stroke guide wire, which is suitable for the rapid-exchange surgery system and shortens the operation time. The doctor can personally control the guide wire, reduce surgical operators, reduce complications, and improve the success rate of surgery. At the same time, the long-stroke Guidewires still apply. In the commonly used rapid exchange inserter, the distal end of the zebra guide wire is passed through the endoscope directly to the patient's affected area, and then the proximal end of the zebra guide wire is inserted into the inner tube of the rapid exchange inserter, at about 250-300mm. The zebra guide wire passes through the inner tube and the outer tube through a sloped part guide, lock the proximal end of the zebra guide wire on the hand...

AI Technical Summary

Problems solved by technology

Because the existing inner tube is dented, it is easy to form a barrier to the introduction of the zebra guide wire. During the operation, the doctor needs to wear the zebra guide wire on site. Due to the existence of the slope and the transition of the parts, the guidance requirements for the slope parts are very high at this time, and often There will be poor guidance, and the zebra guide wire cannot pass through the inner and outer tubes at one time, so a lot of time is often wasted in passing the zebra guide wire, and improper operation will also lead to the failure of the zebra guide wire

At the same time, due to the particularity of the operation, the zebra guide wire cannot be put on in advance. Since the operation is often a race against time, it becomes an important technical problem to quickly pass the zebra guide wire 100%
