A More Reliable Rapid Exchange Inserter

Abstract

The invention discloses a more reliable fast exchanging imbedding device. The more reliable fast exchanging imbedding device comprises an outer pipe, one end of the outer pipe is provided with a sharp pipe, an inner pipe is embedded into the outer pipe, the position, corresponding to the inner pipe, of the outer pipe is provided with a guiding groove, a channel for a zebra wire to penetrate through is formed from the guiding channel to the center of the sharp pipe, the channel is internally provided with a guiding pipe with the diameter larger than that of the zebra wire, and one end of the guiding pipe extends out of the guiding groove. By means of the guiding of the special guiding pipe, the zebra wire can penetrate out of the inner pipe and the outer pipe successfully, and the fast exchanging requirement can be met.

Description

technical field [0001] The invention relates to a medical inserter device, in particular to a more reliable rapid exchange inserter. 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 handle of the endo...

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%
