Description
Technical field
This utility model relates to a kind of medical instruments field, particularly fixedly connects lead device in a kind of peritoneal dialysis catheters stomach wall.
Background technology
Peritoneal dialysis is patients with renal failure or the clinical commonly used and effective kidney Replacement Therapy of acute renal failure in whole latter stage.Peritoneal dialysis is to utilize peritoneum as semipermeable membrane, utilizes action of gravity that the dialysis solution for preparing is poured into patient's peritoneal cavity through conduit, exists the Concentraton gradient of solute poor in the peritoneum both sides, and the solute of high concentration one side is to low concentration one side shifting; Moisture then oozes a side shifting from a hypotonic side direction height.Constantly change by abdominal dialysis liquid, to reach the purpose of removing interior metabolism product, toxicant and correcting water, electrolyte balance disorder.Usually, adopt free-standing peritoneal dialysis catheters art method to carry out peritoneal dialysis catheters before peritoneal dialysis, the peritoneal dialysis catheters that is about to a special use is implanted male patient's bladder rectum crypts or women patient uterus rectum crypts.Because peritoneal dialysis catheters is not fixed on the abdominal cavity, the easy floating displacement of peritoneal dialysis catheters in the patients with implantation body, so conventional free-standing peritoneal dialysis catheters postoperative, the floating displacement of peritoneal dialysis catheters occurs in nearly 15-20% patient, cause peritoneal dialysis to be difficult to carry out, need again surgical catheters, increased patient's misery and economic pressures.
Drift about for fear of peritoneal dialysis catheters, can in operation, enlarge otch, be extended down to superior margin of pubic symphysis 2-3cm place downwards, again cut herein theca of rectus abdominis muscle, rectus abdominis m., rear sheath and peritoneum, after with a rhizoid line peritoneal dialysis catheters front end being pricked apart from interior silk ribbon human relations cover 4-6 cm place cover, abdominal subcutaneous flesh layer is fixed in stitching again.There is distinct disadvantage in this method: tissue injury is large, operating difficulty is large, operating time is long.A kind of patent No. is 200810232907.5 peritoneal dialysis catheters holder technology, the mentality of designing of this holder is: peritoneal dialysis tube planting operation otch cuts skin, subcutaneous tissue, theca of rectus abdominis muscle, rectus abdominis m., rear sheath and peritoneum and enters the abdominal cavity routinely, in incision peritoneum and rear sheath are made a pocket, do not tighten up temporarily pocket.The sleeve pipe of holder is inserted abdominal cavity and lower mobile forward along stomach wall along pocket, until the umbilicus median line is apart from the about 4-6cm of pocket otch place, with the stomach wall jack-up that makes progress.The tube core of putting into sleeve pipe is promoted forward until penetrate the stomach wall layer.Get 1-No. 4 silk threads, the knot of band is laid in the center, and ring diameter is slightly larger than the peritoneal dialysis catheters diameter.After these silk thread two ends are penetrated the puncture needle uropore, puncture needle is put into tube core, keeping the middle loops of silk thread under the outside prerequisite in abdominal cavity, pocket place, puncture needle is pulled out from the tube core front end, the two ends that silk thread is dissociated are worn the abdominal cavity and are gone out, and band link one end still remains on the outer incision abdominal cavity of lotus outside.When inserting peritoneal dialysis catheters, only need conduit is inserted in first in the silk thread ring, enter the abdominal cavity by pocket again catheter proximal end is put into male's bladder rectum crypts or women uterus rectum crypts.Tighten up gently the suture two ends, make suture middle part ringlet behind the corresponding fixing point of peritoneal dialysis catheter immigration intraperitoneal, the knotting of suture two ends is fixing; Tighten up 2 layers of pocket, layer-by-layer suture protheca, subcutaneous and skin.Although it makes things convenient for peritoneal dialysis catheters to be fixed on front stomach wall, except low operating difficulty, reduced tissue injury, but the operation middle sleeve is by the intraperitoneal jack-up stomach wall that makes progress, outwards penetrate stomach wall by tube core and suture introducing needle from intraperitoneal, have the following disadvantages: 1. the local anesthesia setting of casing is by the intraperitoneal jack-up stomach wall that makes progress, when wearing out stomach wall with tube core, the obvious pain of patient is uncomfortable, even is difficult to tolerance; 2. because tube core is under the condition of sleeve pipe channeling direction fixed position, penetrate from inside to outside stomach wall, strength is difficult to conduct to the tube core front end, is meeting obesity or the strong patient of abdominal muscles, and often difficulty is larger; 3. behind the Reusability, there is the potential risk that ruptures and fall into the patient abdominal cavity in the tube core tip when penetrating the stomach wall layer.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides and fixedly connects lead device in a kind of peritoneal dialysis catheters stomach wall, and it can prevent the peritoneal dialysis catheter displacement, alleviates tissue injury, reduces operating difficulty, increases operation safety and success rate.
The purpose of this utility model is achieved in that
