微小阻塞性牵开器

Minimally obstructive retractor
Abstract:
This application presents minimally-obstructive and structurally-adjustable retractors which afford an open work area of desirable size and enhanced visualization for a surgeon about the perineum and the posterior vaginal wall of the patient. The retractors may be lightweight and compact, and also configured and dimensioned to minimize slippage during use. The retractors may retract the engorged labia of the postpartum patient as well as the vaginal walls. The device may also be used as a speculum.
