Problems solved by technology

[0004] The disadvantage of this surgical method is that the surgical incision is too large, and it is easy to cause peritoneal tear damage when suturing on the peritoneum, and the incidence of postoperative peritoneal fluid leakage is high

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0028] see figure 1 , figure 2 , a buckle for peritoneal dialysis catheterization, comprising a central shaft 3, the central shaft 3 is provided with a central through hole for the peritoneal dialysis pipeline (peritoneal dialysis tube) to pass through, and the upper and lower ends of the central shaft are respectively provided with an upper blade 1 and a lower blade 2. The upper blade 1 and the lower blade 2 are provided with evenly distributed perforations;

[0029] The shaft wall of the central shaft is provided with small holes 5 that are distributed in a spiral shape, and the sliding wires pass through the small holes in turn;

[0030] The connecting wire 5 passes through the central through hole and passes through the corresponding perforations of the upper blade 1 and the lower blad...

Abstract

The invention discloses a buckle for catherization for peritoneal dialysis. The buckle comprises a middle shaft; a central through hole through which a peritoneal dialysis tube can pass is formed in the middle shaft; upper and lower ends of the middle shaft are provided with upper and lower blades respectively; the upper and lower blades are provided with through holes; small holes are spirally distributed in the shaft wall of the middle shaft in an annular shape, and a sliding line sequentially passes through the small holes; and connection lines pass through the corresponding through holes of the upper and lower blades through the central through hole sequentially. In the catherization for peritoneal dialysis, a large incision is not needed to enter an abdominal wall, a peritoneum is not needed to be incised, and operation is finished by a mode that the peritoneum is punctured so as to form a notch, and the buckle is placed in the notch, so that the operation incision can be reduced by 2 cm, the peritoneum can be prevented from torn during operation, and the occurrence rate of postoperative peritoneal dialysis liquid leakage can be reduced.

Description

technical field [0001] The invention belongs to the technical field of devices for peritoneal dialysis catheterization, and relates to a buckle for peritoneal dialysis catheterization. Background technique [0002] Peritoneal dialysis is a renal replacement therapy for patients with chronic renal failure. Before peritoneal dialysis treatment, peritoneal dialysis catheterization is required to establish a passage for peritoneal dialysis fluid to enter and exit the peritoneal cavity. [0003] The traditional peritoneal dialysis catheterization is an open operation. The method is to make a 5cm long incision on the abdominal wall, cut to the peritoneum layer by layer, make a 0.8cm long incision on the peritoneum, and make a circle around the incision with silk thread Purse string suture is used to insert the peritoneal dialysis tube from the incision into the abdominal cavity, then the purse string suture is tightened and ligated to fix the peritoneal dialysis tube on the perito...
