VAGINAL OBTURATOR Russian patent published in 2006 - IPC A61B17/42 

FIELD: medical engineering.

SUBSTANCE: device has bushing having internal surface engageable with guide member and flexible disk-shaped sealing members. The flexible disk-shaped sealing members are placed in grooves on outer bushing surface. Maximum flexible disk-shaped sealing members dimensions grow when moving towards idle bushing end. The bushing has at least one additional flexible disk-shaped sealing member. Additional flexible disk-shaped sealing member dimensions are equal to maximum flexible disk-shaped sealing member dimensions. Flexible disk-shaped sealing member having minimum dimensions and flexible disk-shaped sealing member placed near the former one have common surfaces rounded near the working bushing end. Flexible disk-shaped sealing member having maximum dimensions and at least one additional flexible disk-shaped sealing member have guide members with symmetrically rounded edges. The rounded guide members are conjugated with bevels. The bevels are produced on flexible disk-shaped sealing members on the working bushing end side and are equal in length to at least 1/4 times difference between external bushing diameter and maximum size of additional flexible disk-shaped sealing member. Locking member is available on the idle bushing end side.

EFFECT: improved surface engagement conditions of obturator and vagina; facilitated surgeon working conditions.
