8 results about "Endoscopic stent" patented technology

The present invention relates to the technical field of image processing, and particularly to an endoscopic robot stent defect detection method based on machine vision, comprising: acquiring a foreground stent image of an endoscopic robot and segmenting the foreground stent image into a plurality of regions; screening out crack connected regions from the connected regions in the regions according to the possibility of the connected regions in the regions being crack connected regions; obtaining a plurality of crack splicing regions according to the direction similarity and endpoint connectivity between adjacent crack connected regions; obtaining the number of seed points placed in the crack splicing regions according to the distribution of the skeleton pixel points and the upper edge pixel points of the contour of the crack splicing regions in the crack splicing regions; obtaining the final crack region according to the number of seed points placed in the crack splicing regions; and determining the quality of the endoscopic stent according to the final crack region. By analyzing the foreground stent image of the endoscopic robot, the present invention improves the accuracy of defect detection.

An assembly for use in endoscopic stent delivery, including a stent delivery device and an associated stent loaded therein. The stent delivery device includes an outer tubular member, an inner member slidably disposed within the lumen of the outer tubular member, and a distal tip disposed at the distal end of the inner member. A self-expanding stent is positioned within the outer tubular member in a compressed configuration, with one or more suture loops constraining at least a portion of the stent. Upon deployment of the stent from the stent delivery device, proximal withdrawal of a release suture unravels the one or more suture loops.

This invention relates to an anti-displacement adaptive self-locking human endovascular stent and its manufacturing method, belonging to the field of medical devices. The invention includes a stent unit and a connecting unit, with adjacent stent units connected by the connecting unit. Its structural features are as follows: each stent unit includes a main frame arranged in a rhomboid structure, and connecting beams, transition beams, and tenon-and-mortise beams disposed within the main frame. The connecting beams, transition beams, and tenon-and-mortise beams are connected sequentially. Both the connecting beams and the tenon-and-mortise beams are connected to the main frame. Each of the two tenon-and-mortise beams has multiple tenons, with mortises formed between adjacent tenons. A tenon on one tenon-and-mortise beam connects to a mortise on another tenon-and-mortise beam, wherein the number of tenons is not less than three, and the number of mortises is not less than two.

An assembly for use in endoscopic stent delivery, including a stent delivery device and an associated stent loaded therein. The stent delivery device includes an outer tubular member, an inner member slidably disposed within the lumen of the outer tubular member, and a distal tip disposed at the distal end of the inner member. A self-expanding stent is positioned within the outer tubular member in a compressed configuration, with one or more retaining loops extending from the body of the stent and engaged with a retaining structure, such as a notch, provided by the distal tip. Upon deployment of the stent from the stent delivery device, proximal withdrawal of the distal tip through the lumen of the stent disengages the one or more retaining loops from the retaining structure.
