Description
Technical field
The present invention relates to medical apparatus technical field, dedicated surgical device when being cut off more particularly, to uterus canceration vaginal canal
Tool.
Background technique
Cervical carcinoma is the most common gynecologic malignant tumor, and carcinoma in situ high incidence age is 30~35 years old, and infiltrating carcinoma is 45~55
Year, in recent years its morbidity have the tendency that rejuvenation, position of being number three in the most common cancer of women；According to clinical stages, patient
Age, fertility requirement, systemic conditions, medical technique level and appointed condition etc., which comprehensively consider, formulates individualized treatment side appropriate
Case uses based on operation and radiotherapy, the comprehensive therapeutic plan supplemented by chemotherapy:
Operative treatment: operation is mainly used for early cervical carcinoma patient；Common art formula has: complete hysterectomy；Secondary son complete extensively
Palace resection and pelvic lymphadenectomy；Radical hysterectomy and pelvic lymphadenectomy；Lymph by abdominal aorta
Excision or sampling；Young patient ovary can normally retain, and to the young patient for retaining reproductive function is required, belong to special early stage
Feasible conization or Radical trachelectomy.
Radiotherapy: 1) middle and advanced stage patient；2) systemic conditions are not suitable for the early stage patient of operation；3) uterine neck bulk lesion
Preoperation radiotherapy；4) discovery of operative treatment pathologic finding has the adjuvant treatment of high risk factor.
Chemotherapy: being mainly used for the patient of advanced stage or relapse and metastasis, in recent years also using operation joint Neoadjuvant chemotherapy (vein
Or Intraarterial Chemotherapy) reduce tumor focus and the subclinical transfer of control, it is also used for radio therapy sensitization.
Wherein, complete hysterectomy occupies larger proportion as most common art formula in clinical treatment；Due to cancer cell
Can implanting, just determine in this that operation will ensure cancer cell indiffusion, not flow out；1) this existing therapy is specifically included that
Open resection: tradition struts abdominal incision by utensil, and manual tool cuts the conjunction of vaginal canal parietal suture, finally by uterus from notch
It removes, the surface of a wound caused by the art formula is larger, is unfavorable for the healing of patient abdomen wound；
2) ultrasound knife probeed into after intravaginal suture by laparoscope puncture outfit hole is gradually sheared from vaginal canal periphery；This kind of art formula
It needs first to be put into uterus raising device to intravaginal, vaginal canal is then bound by uterus raising device by suture suture manually, finally by
Ultrasound knife cuts out osculum from vagina pipe outer wall, is then circumferentially gradually sheared by osculum along vaginal canal, will eventually by clamp
Uterus is pulled out from vaginal canal；This mode is performed the operation time-consuming and laborious though wounds are smaller, is especially fettered in manual suture
During, it cannot be guaranteed that constraint is reliable, and cutting mode is very long, and efficiency is extremely low.
Thus present applicant proposes a kind of mode for carrying out ring cutting detachment vaginal canal from vagina inside pipe wall, consider at the same time
To traditional radially-protruding blade of ring cutting mode in cutting in the presence of the risk of incised wound surrounding tissue, the application will also solve together
Certainly.
