Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable open peritoneal dialysis surgery purse-string suture auxiliary catheter. Background Art

[0002] Peritoneal dialysis catheterization is a technique that selects the most appropriate peritoneal dialysis catheterization point and accurately places the end of the abdominal section of the catheter in the rectovaginal pouch or the uterorectal pouch. The purpose of catheterization is to establish a pathway for peritoneal dialysis fluid to enter and exit the abdominal cavity. Establishing an unobstructed peritoneal dialysis pathway is the primary condition for peritoneal dialysis and is also a key step. This technique is mostly used for acute and chronic renal failure, multiple myeloma, acute poisoning or refractory congestive heart failure.

[0003] The existing purse-string suturing work in open peritoneal dialysis catheterization has certain drawbacks. First, during the operation of open peritoneal dialysis catheterization, when the purse-string suturing of the posterior sheath is performed, the greater omentum and the intestinal tract of the abdominal cavity are very likely to flow out of the posterior sheath outlet, which greatly increases the difficulty of purse-string suturing, operation time, patient pain and the risk of damaging intra-abdominal tissues.

[0004] Therefore, we propose a disposable open peritoneal dialysis surgery purse-string suture auxiliary catheter to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a disposable open peritoneal dialysis surgery purse-string suture auxiliary catheter, which solves the above-mentioned technical problems.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disposable open peritoneal dialysis surgery purse-string suture auxiliary catheter, comprising an auxiliary catheter body, a drainage portion is provided at the end of the auxiliary catheter body, a drainage port is opened at the end of the drainage portion, a silicone water bag is sleeved on the surface of the auxiliary catheter body, a liquid storage cavity is provided inside the silicone water bag, an injection tube is penetrated on the surface of the silicone water bag, and the end of the injection tube is connected to the liquid storage cavity.

[0007] Preferably, a plurality of side holes are formed through the surface of the drainage portion.

[0008] Preferably, a rubber head is fixedly installed at one end of the injection tube away from the silicone water bag, the surface of the injection tube is fixedly arranged inside the auxiliary catheter body, both ends of the injection tube pass through the auxiliary catheter body, and the rubber head is located outside the auxiliary catheter body.

[0009] Preferably, a connector is provided at one end of the auxiliary catheter body away from the drainage portion, and a container is detachably mounted on the connector.

[0010] Compared with the related art, the disposable open peritoneal dialysis surgery purse-string suture auxiliary catheter provided by the utility model has the following beneficial effects:

[0011] The utility model provides a disposable open peritoneal dialysis surgery purse-string suturing auxiliary catheter. First, the drainage part of the auxiliary catheter body is placed in the peritoneal incision, and the silicone water bag is located inside the peritoneal incision. Then, liquid is injected into the liquid storage cavity through an injection tube. The silicone water bag is gradually squeezed and expanded by the liquid inside the liquid storage cavity, and the peritoneal incision is blocked by the expanded silicone water bag. Then, a ring-shaped closing purse can be sewed on the peritoneal incision with surgical thread. After the peritoneal incision is sutured, the liquid inside the liquid storage cavity is discharged through the injection tube, so that the silicone water bag is relaxed and the silicone water bag and the auxiliary catheter body can be pulled out from the peritoneal incision. When medical staff perform purse-string suturing, the situation of intestinal gushing or ascites outflowing due to the patient's breathing will not occur, the peritoneal incision can be effectively sutured, and the risk of infection is reduced. The device has a simple structure and is easy to operate, which is conducive to popularization. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] See also Figure 1-Figure 3 The utility model provides a technical solution, including an auxiliary catheter body 1, a drainage portion 11 is provided at the end of the auxiliary catheter body 1, a drainage port 12 is provided at the end of the drainage portion 11, a silicone water bag 2 is sleeved on the surface of the auxiliary catheter body 1, a liquid storage cavity 24 is provided inside the silicone water bag 2, an injection tube 22 is provided on the surface of the silicone water bag 2, and the end of the injection tube 22 is connected to the liquid storage cavity 24;

[0017] First, the drainage part 11 of the auxiliary catheter body 1 is placed into the peritoneal incision, and the silicone water bag 2 is located inside the peritoneal incision, and then liquid is injected into the liquid storage cavity 24 through the injection tube 22. The silicone water bag 2 is gradually squeezed and expanded by the liquid inside the liquid storage cavity 24, and the peritoneal incision is blocked by the expanded silicone water bag 2. Then, a ring-shaped purse can be sewed on the peritoneal incision with surgical thread. After the peritoneal incision is sutured, the liquid inside the liquid storage cavity 24 is discharged through the injection tube 22, so that the silicone water bag 2 is relaxed and the silicone water bag 2 and the auxiliary catheter body 1 can be pulled out from the peritoneal incision. When the medical staff performs the purse suturing, there will be no intestinal gushing or ascites outflow due to the patient's breathing, and the peritoneal incision can be effectively sutured while reducing the risk of infection. The device has a simple structure and is easy to operate, which is conducive to promotion.

[0018] A plurality of side holes 13 are formed through the surface of the drainage portion 11. Adding a plurality of side holes 13 on the surface of the drainage portion 11 effectively improves the drainage efficiency of the auxiliary catheter body 1, and avoids the situation in which the side holes 13 are blocked and drainage is impossible, thereby ensuring the stable drainage operation.

[0019] A rubber head 23 is fixedly installed at one end of the injection tube 22 away from the silicone water bag 2. The surface of the injection tube 22 is fixedly arranged inside the auxiliary catheter body 1. Both ends of the injection tube 22 pass through the auxiliary catheter body 1, and the rubber head 23 is located on the outside of the auxiliary catheter body 1. Due to the sealing effect of the rubber head 23, the liquid can be effectively retained after being injected into the liquid storage cavity 24, maintaining the normal expansion of the silicone water bag 2, and at the same time, the liquid inside the liquid storage cavity 24 can be smoothly extracted using a syringe.

[0020] A connector 21 is provided at one end of the auxiliary catheter body 1 away from the drainage portion 11, and a container is detachably mounted on the connector 21;

[0021] When the auxiliary catheter body 1 is used for drainage, the connection piece 21 enables the auxiliary catheter body 1 to be quickly connected to a container containing liquid, thereby further improving convenience.
