Embodiment Construction

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to make a clearer and clearer definition of the protection scope of the present invention.

[0017] See attached Figure 1-4 As shown, a medical stent in this embodiment includes a stent body 1, the length of the stent body 1 is 5-100 mm, the stent body 1 is made of polylactic acid polymer or bioabsorbable magnesium alloy, and the stent body 1 has The channel, the balloon 4 is installed in the channel, the stent body 1 and the balloon 4 are not connected, and are in a separated state. The balloon 4 has an inflatable and exhaustable connection port. When the balloon 4 is inflated, the stent body 1 follows After the balloon 4 is inflated, the stent body 1 is fixed on the lesion, and the stent implanted in the stenosis of th...

Abstract

The invention discloses a medical stent, comprising a stent body, a channel inside the stent body, a balloon is installed in the channel, the stent body is separated from the balloon, and when the balloon is inflated, the stent The body is supported to the expanded state; when the balloon is pumped, the stent body is fixed on the lesion, the stent body is made of polylactic acid polymer or bioabsorbable magnesium alloy, and the surface of the stent body is coated with There is a degradable and expandable protective film of anti-inflammatory drugs. The present invention uses polylactic acid polymer as the stent body, and this material has the function of full biodegradation; the surface of the stent body is coated with a degradable anti-inflammatory drug protective film that can expand with the stent body, and the anti-inflammatory drug protective film can protect The stent enables the stent to degrade rapidly, and plays an anti-inflammatory treatment effect on the lesion, reduces the number of reoperations and repeated inspections, and reduces the pain and economic burden of the patient.

Description

Technical field [0001] The invention relates to a system device for treating pathological blockage, belonging to the field of medical equipment, and in particular to a medical stent. Background technique [0002] Existing lesion dilation, such as sinus balloon dilation to treat sinusitis, after a period of time, the diseased part of the sinus ostium will become narrow again, leading to recurrence of the disease, which requires a second operation and repeated examinations. It will increase the suffering and financial burden of patients. [0003] In a Chinese invention patent with the authorization announcement number CN 201899590U and the authorization announcement date of 2011.07.20, a balloon-expandable fully degradable intravascular stent is disclosed. The stent can be made of polycarbonate materials and polylactic acid. This kind of material, as well as the polylactic acid-polyglycolic acid material, is formed into a tube wall shape by laser etching, which is completely degrada...
