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.
Claims14
A minimally obstructive retractor having a proximal end and a distal end, and an exterior surface and an interior surface comprising:
- a central body portion,
- at least two wings, and
- at least two hinges, each configured to affix a different one of the at least two wings to the central body portion;
- wherein the central body portion, the at least two wings, and the at least two hinges form a canopy such that the fluid flow through the exterior surface of the canopy, defined by the exterior surfaces of the body, wings and hinges, is substantially blocked.
