Description
Technical field
The utility model belongs to the field of medical instrument technology more particularly to a kind of female ureter bracket extractor.
Background technique
Damage and the formation of postoperative ureterostoma are one of the risk symptoms that gynaecology can often encounter in ureter art.According to urine output
Pipe traveling feature, easy damaged part are predominantly located at pelvic cavity, including ureter is crossed and entered at blood vessel, below uterine artery inside and outside ilium
On the outside of uterosacral ligament and at cardinal ligament, bladder inlet;The displacement of tumor of pelvis passage simultaneously, tumor-infiltrated, mullerianosis
Disease, inflammation adhesion, the past operation on pelvis history etc. lead to topography level, ureter position change, and big section is free in gynaecology's art
Ureter, the excessive connective tissue of removing, or ligatured too close to uterine artery root, ureter blood supply is damaged, is caused postoperative defeated
Urinary catheter ischemic, necrosis, because coagulation or cutting cause ureter thermal damage etc. in the laparoscopic surgery being especially widely used at present,
It is the reason of ureteral injury in gynecological surgery occurs.
Therefore, at present in clinical position, as preoperative evaluation need row radical hysterectomy, there are tumour passage infiltration or son
Endometriosis and inflammation adhesion wait injury of ureter high risk condition again when, it is placed in bilateral ureteral in advance before gynecological surgery
Bracket plays a supporting role in protection simultaneously to indicate that ureter traveling avoids damaging in art in more preferable art, avoids postoperative lack
Postoperative ureterostenosis even ureterostoma caused by blood, necrosis, inflammation package etc..The ureter bracket of preventative merging is usual
It needs to take out at 1 month or so after surgery, traditional pipe mode that takes is to enter urethra by cystoscope, looks at lower nipper clamp bilateral straight
Ureter bracket " J " type tail end is extracted, but this mode needs to anaesthetize down using cystoscope, and process is cumbersome, it has not been convenient to, and pelvic cavity
The postoperative female patient urethra local susceptibility of gynaecology increases, and patient is easily made to generate pain and discomfort, while postoperative pelvic tissue knot
Structure changes, such as misoperation, and rigid cystoscope will also result in unnecessary urethral injury and surrounding organ damage.
