Abstract

The invention relates to a supporting stand secondary releasing introducer under the direct vision of an endoscope. An outer tube is fixed at the front end of a front handle. A mark ring is arranged at the tail end of the outer tube. An inner tube is fixed at the front end of a back handle. The inner tube goes through the front handle and is inserted into the outer tube. A supporting stand is arranged between the outer and the inner tubes. A tapered soft head is arranged on the inner tube installed at the front end of the supporting stand. A travelling handle is sleeved and connected in a sliding way on the inner tube arranged between the front and the back handles. The travelling handle has detachable connection with the inner tube. A locating piece is arranged between the travelling handle and the inner tube. The introducer can realize the secondary releasing of the supporting stand and has the advantage of accurate location.

Description

technical field [0001] The invention relates to a medical device, especially a surgical auxiliary device for the treatment of human non-vascular lumen, especially pylorus, duodenum and colon diseases, which needs to be inserted into an artificial stent, specifically an endoscopic direct vision device. Lower the accurately positioned stent secondary release inserter. Background technique [0002] At present, the method of using stent implantation to treat human non-vascular diseases has been very common, and it has been proved to be an effective treatment method in the treatment of certain diseases, and it has low surgical risk, minimally invasiveness, patient It has the advantages of less pain, short operation time and low cost, and has gradually developed from the treatment of malignant diseases to the wide application of benign diseases. [0003] Along with the development of stents, people have also invented various stent implanters, such as Chinese patents ZL99220256.6,...
