The invention discloses a silicone stent conveying device. The silicone stent conveying device comprises an outer conveying rod and an inner conveying rod, wherein the outer conveying rod comprises anouter sleeve with a tubular structure, a first slot which is through is formed in the side wall, close to the far end, of the outer sleeve and extends in the axial direction to penetrate the wall ofthe far end, so that a first accommodating groove extending in the axial direction is formed in the part, close to the far end, of the outer sleeve, and length of the first accommodating groove is notsmaller than that of a to-be-conveyed silicone stent; the inner conveying rod comprises an inner sleeve with a tubular structure, a second slot which is through is formed in the side wall, close to the far end, of the inner sleeve and extends in the axial direction to penetrate the wall of the far end, so that a second accommodating groove extending in the axial direction is formed in the part, close to the far end, of the inner sleeve, and length of the second accommodating groove is not smaller than that of the to-be-conveyed silicone stent; the inner sleeve can be coaxially sleeved with the outer sleeve, and the outer sleeve and the inner sleeve can rotate relatively around the axis. The conveying device is simple in structure, operating steps are simple, and the implantation risk of the silicone stent can be effectively reduced.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a silicone stent delivery device. Background technique [0002] Stenosis of the trachea and bronchi caused by inflammatory granulomas, scars, tumors and other lesions often easily lead to problems such as poor breathing and insufficient blood supply, and severe cases may be life-threatening. Stent implantation is one of the important means to treat airway stenosis. Silicone stent is the earliest airway stent developed. It has the advantages of low price and good biocompatibility. It is suitable for trachea, bronchi and other luminal parts. Treatment of strictures and lesions. However, due to the high tension of the silicone stent, the delivery process needs to be carried out under the guidance of a rigid bronchoscope. At the same time, the patient needs to be under general anesthesia to ensure the ventilation function, which makes the implantation of the silicone stent m...
