PCT No. PCT/SE96/00663 Sec. 371 Date Dec. 31, 1997 Sec. 102(e) Date Dec. 31, 1997 PCT Filed May 22, 1996 PCT Pub. No. WO97/01983 PCT Pub. Date Jan. 23, 1997A vaginal speculum comprises two elements (1, 2) having on one hand a spoon part possible to insert in a woman's vagina (3, 5) and on the other hand an oblique handle part (4, 6). After insertion in the vagina, the spoon parts are movable through displacement of the handle parts so that said parts may widen the vagina. There is an aperture of inspection in one handle part (4), the handle parts (4, 6) having co-operating looking means for locking the parts (1, 2) in relation to each other. The upper as well as the lower spoon part (3, 5) have longitudinally curved shape. More precisely, said spoon parts have such a shape that they diverge with at least 30 DEG from concavely curved intermediate portions (17, 17') towards convexly curved portions (18, 18'), the distance between the convexly curved portions (18, 18') being considerably larger than the corresponding distance between the concavely curved portions (17, 17'). In such a way, the pinching muscle of the opening of the vagina reliably retains the spoon parts inside the vagina. |
