Fast exchanging imbedding device with smaller wave pipe

Abstract

The invention discloses a fast exchanging imbedding device with a smaller wave pipe. The fast exchanging imbedding device with the smaller wave pipe comprises an outer pipe, one end of the outer pipe is provided with a sharp pipe, and the other end of the outer pipe is provided with a front handle. The wave pipe is embedded into the outer pipe. The position, corresponding to the wave 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 groove to the center of the sharp pipe, and the channel is internally provided with an inner pipe with the diameter larger than that of the zebra wire. The inner pipe is thinner, the external diameter of the inner pipe can be reduced to 1.1 mm from the original 1.3 mm, the external diameter of a liner channel fast exchanging imbedding device can be reduced to smaller 7F from the original 8F, and a fast exchanging liner channel support on the market at present only can be reduced to 8F. Due to the fact that the inner pipe is the stainless steel wave pipe, the tail end infusion function is achieved.

Description

technical field [0001] The invention relates to a medical inserter device, in particular to a rapid exchange inserter for smaller 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 handle of ...

AI Technical Summary

Problems solved by technology

After a PEEK tube is dented, it becomes airtight and can no longer pass liquid, so the endoscopic rapid exchange inserter products on the market do not support the tail end infusion function
