Dilator with spirally-arranged protruding portion for medical procedures
A recently granted patent (Publication Number: US11883067B2) discloses a dilator designed with a unique spirally-arranged protruding portion on its outer surface. The dilator comprises a hollow shaft with a tapered section, where the diameter increases from the distal end towards the proximal end. The spirally-arranged protruding portion includes spirally-arranged protruding sections with gaps between them along the axial direction of the shaft. This protruding portion features an apex section with the greatest height in a transverse cross-section, along with a side surface section that extends outward from the apex section towards the outer surface. The side surface section is inclined linearly towards either the distal or proximal end direction, creating a coil body by winding a wire around the outer surface of the hollow shaft.
Furthermore, the patent claims specify additional features of the dilator, such as a contour line of the side surface section that includes a portion with a concave shape in the transverse cross-section of the spirally-arranged protruding portion. Additionally, the coil body and the hollow shaft are joined at a specific joint, with part of the inclined surface arranged directly above this joint in the coil body. These design elements aim to enhance the functionality and effectiveness of the dilator for its intended medical or surgical applications.
