Description

TECHNICAL FIELD

[0001] The utility model relates to a guiding device for peritoneal dialysis catheterization. BACKGROUND

[0002] Peritoneal dialysis is one of the dialysis methods for uremic patients. Peritoneal dialysis catheterization is to implant a peritoneal dialysis tube into the patient's abdominal cavity for permanent retention for peritoneal dialysis. The common complication after catheterization is peritoneal dialysis tube migration, which affects the peritoneal dialysis of the patient. The use of peritoneal dialysis tube fixation method during surgery can greatly reduce the incidence of peritoneal dialysis tube migration. The peritoneal dialysis tube fixation methods in various hospitals are different. Our hospital uses a needle to suture below the peritoneal incision, and the distance from the peritoneal incision is as long as possible, but the omentum and intestinal tube block the field of view, and the suture distance cannot be too deep. How to avoid the blockage of the omentum and intestinal tube and expose more space is the key to the success of the fixation surgery. The utility model can push away the omentum and intestinal tube to block more space, the suture position is farther away from the peritoneal incision, the fixation surgery effect is better, the incidence of peritoneal dialysis tube migration can be reduced, and the effect of peritoneal dialysis can be improved.

[0003] In order to prevent the omentum and intestinal tube in the abdominal cavity from blocking the view, as shown in Figure 1 , the current surgical method uses forceps 1 to extend into the abdominal cavity from the peritoneal incision 2, blocks the abdominal cavity tissue 3 (omentum and intestinal tube), and makes a needle into a thread sleeve from the gap of the forceps 1, so that the needle needs to be inserted once and taken out once at the position 7 below the peritoneal incision 2, so as to form a thread sleeve on the peritoneum, which is used as a suture point for fixing the peritoneal dialysis tube, and the peritoneal dialysis tube is placed through the thread sleeve. After the peritoneal dialysis tube is placed, the thread sleeve is tightened to fix the peritoneal dialysis tube on the peritoneum below the peritoneal incision. After the omentum and intestinal tube in the abdominal cavity are pushed away by the forceps 1, the needle is inserted and taken out to make a thread sleeve. As shown in Figure 2 , the position 7 for fixing the peritoneal dialysis tube is 1-2 cm away from the peritoneal incision 6. Because the long forceps cannot completely block the omentum and intestinal tube (the omentum and intestinal tube will come out from between the two feet of the long forceps), the suture point position 7 for fixing the peritoneal dialysis tube is relatively close to the peritoneal incision 6, the fixing effect is poor, and there is a possibility and risk of peritoneal dialysis tube 5 migration (as shown in Figure 2 ).

[0004] In summary, the long forceps are currently used to extend into the abdominal cavity from the peritoneal incision, separate the omentum and intestinal tube, expose the space, and use ordinary suture needles for suture fixation, which has the following defects: the omentum and intestinal tube will squeeze in from the side of the forceps and between the two feet, affecting the operation. UTILITY MODEL CONTENTS

[0005] The present application discloses a guide device for peritoneal dialysis catheterization, which is inserted into a peritoneal incision during surgery, and can completely block the omentum majus and intestinal canal outside, without affecting the position of the fixing suture, so that the position of the fixing suture is deeper.

[0006] According to the embodiment, the guide device for peritoneal dialysis catheterization is a U-shaped groove with a handle, the diameter of the circular arc of the U-shaped groove is 1 cm, the height is 5 cm, and the length of the handle is 5 cm.

[0007] The guide device is used to replace a long tweezer to block the omentum majus and intestinal canal. The two feet of the long tweezer are used to block the omentum majus and intestinal canal, and there is a gap between the two feet, so that the omentum majus and intestinal canal can still squeeze out of the gap and affect the operation. The guide device is a U-shaped groove with a handle, one side of which is closely attached to the visceral peritoneum, and the U-shaped fan can completely block the omentum majus and intestinal canal, so that the vision is better exposed, the position of the fixing suture after the suture is farther away from the peritoneal incision, and the fixing effect is better.

[0008] Compared with the prior art, the technical scheme of the present application has the following beneficial effects: (1) reducing the displacement of the peritoneal dialysis tube during peritoneal dialysis of the patient; (2) the position of the peritoneal dialysis tube is better fixed, and the effect of peritoneal dialysis is better.

DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. These embodiments should be understood as illustrative only and not as limiting the scope of protection of the present invention. After reading the description of the present invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent changes and modifications also fall within the scope defined by the claims of the present invention.

[0016] like Figure 3-1 As shown in the preferred embodiment of this utility model, a guiding device 11 for peritoneal dialysis catheter placement is provided. The guiding device 11 is a U-shaped groove with a handle 12. The semi-cylindrical stainless steel U-shaped groove has an arc diameter of 1cm, a height of 5cm, and a handle length of 5cm. Figure 3-2 As shown, during the operation, the guiding instrument 11 is inserted into the peritoneal incision 13. Because the U-shaped groove is arc-shaped, unlike forceps which have a gap between the two legs, the U-shaped groove can completely block the greater omentum and intestine 14 outside the abdominal cavity, without affecting the position of the fixation suture, and can make the fixation suture position deeper.

[0017] like Figure 4 As shown, using the guiding instrument 11 can make the distance between the peritoneal incision position 17 and the fixation suture position 18 reach 3-5cm, and the peritoneal dialysis tube 16 is better fixed and less prone to displacement.
