Problems solved by technology

When the pigtail tube is used as an adjuvant treatment for extracorporeal lithotripsy for kidney and ureteral stones, it can prevent the occurrence of incarcerated stones and prevent large residual stones from falling into the ureter; Bladder, keep the urinary tract unblocked; when the stent is removed, the stone powder and small particles accumulated on the tube wall can be brought out in one bucket to promote the discharge of stones, but the traditional pigtail tube is round, so when the urine is drained and the stent is pulled out Very few stone powders and small particles are brought out

Embodiment 1

[0016] Such as figure 1 , 2 As shown, a triangular pigtail catheter is made of TPU (polyurethane) plus barium, the cross-sectional area of ​​the tube body 1 is 5F, and the sides of the three prisms of the tube body 1 are equal in length. The overall length of the catheter is 450mm. Both ends of the catheter body 1 are tipped and shaped like a pigtail 2. There are scales 3 and small holes 4 on the tube body 1. The tube body 1 is white and can be visualized under X-ray.

Embodiment 2

[0018] Such as figure 1 , 2 As shown, a triangular pigtail catheter is made of TPU (polyurethane) plus barium, the cross-sectional area of ​​the tube body 1 is 7F, and the sides of the three prisms of the tube body 1 are equal in length. The overall length of the catheter is 450mm. Both ends of the catheter body 1 are tipped and shaped like a pigtail. There are scales 3 and small holes 4 on the tube body 1. The tube body 1 is green and can be visualized under X-ray.

Embodiment 3

[0020] Such as figure 1 , 2 As shown, a triangular pigtail catheter is made of TPU (polyurethane) plus barium, the cross-sectional area of ​​the tube body 1 is 8F, and the sides of the three prisms of the tube body 1 are equal in length. The overall length of the catheter is 450mm. Both ends of the catheter body 1 are tipped and shaped like a pigtail. There are scales 3 and small holes 4 on the tube body 1. The tube body 1 is yellow and can be visualized under X-ray.

Abstract

The invention discloses a prism-shaped pigtail conduit comprising a conduit body, wherein the conduit body is shaped like a prism, and the perimeter of the cross section of the conduit body is 5F-8F. Relative to a circular conduit body, the prism-shaped conduit body has the advantages that the space is larger, the larger area of calculus powders can be absorbed, and the calculus can be promoted to be discharged easily.

Description

technical field [0001] The invention relates to a catheter, in particular to a triangular pigtail catheter. Background technique [0002] Since its first clinical use in 1978, pigtail catheters have been widely used in urological kidney, ureter, and bladder operations. The postoperative management area is simplified for patients who use pigtail catheter drainage, because patients with catheters can move early, reduce the chance of infection, significantly reduce the workload of nursing, patients recover quickly after surgery, and the hospital stay is significantly shortened. When the pigtail tube is used as an adjuvant treatment for extracorporeal lithotripsy for kidney and ureteral stones, it can prevent the occurrence of incarcerated stone streets and prevent large residual stones from falling into the ureter; it can make the ureter moderately loose, and the urine can be drained along the stent through the abdominal wall effect. Bladder, to keep the urinary tract unblocke...
