Abstract:

Objective To design an automatic vaginal retractor with suction and to evaluate its effects of clinical application. Methods An automatic vaginal retractor with suction was designed and manufactured. 100 patients diagnosed with high-grade cervical squamous intraepithelial carcinoma（HSIL） and admitted for cervix cold knife conization were enrolled between March and November 2019 in a tertiary obstetrics and gynecology hospital in Zhejiang Province. 50 patients were designated randomly into an experimental group applied with the automatic vaginal retractor with suction during the surgery;L shaped vaginal retractor was used in other 50 patients designated into the control group. Medical staff number （surgeons and nurses） needed for conization,operation time,intraoperative blood loss,incidence of perioperative complication and medical staff satisfaction were evaluated. Results Staff（surgeons and nurses） number in conization during the use of the vaginal automatic retractor with suction was 1-2 instead of 3 in the control group during the use of L shaped vaginal retractor（t=-23.19,P<0.001）. The experimental group applied with automatic vaginal retractor with suction had significantly shorter total operation time（26.20±7.75 min vs 36.28±9.66 min）（t=-5.75,P<0.001）,lower intraoperative blood loss（31.20±19.75 ml vs 48.50±32.12 ml）（t=-3.244,P=0.002）in comparison with those in the control group with the L shaped vaginal retractor,no perioperative complication was observed in either group. Conclusion The automatic vaginal retractor with suction can save medical human resources,reduce operation time and intraoperative blood loss in the cervix cold knife conization,and offer protection for medical staff and patients by automatic suction of blood in operation area and surgical smoker.
