METHOD AND DEVICE FOR CARRYING OUT MINIMUM INVASIVE ACCESS FOR MAKING SURGICAL ABDOMINAL AND GYNECOLOGICAL OPERATIONS Russian patent published in 2005 - IPC

FIELD: medicine; medical engineering.

SUBSTANCE: method involves piercing anterior abdominal wall tissues. Device is set into the abdominal cavity. The abdominal cavity is filled with gas. Mechanical stretching of tissues is carried out along pierce hole perimeter to make its size enough for performing visual control of surgical actions. Abdominal cavity is unsealed and minimum scale surgical intervention is carried out. Then, the abdominal cavity is sealed and the operation is to be continued with laparoscopic stage. Device has ring-shaped body, spatulas, removable cover having sealing member and stiletto mounted on the cover. The cover and stiletto are coaxially mounted with the ring-shaped device body on its external surface. The spatulas have three parts - the upper one, the middle one and the lower one. The parts are arranged at the same angle to each other and form a convex structure. The convex structure is directed towards inside of the ring-shaped body. The lower part of the spatulas surrounds the stiletto allover its whole length. A hinge having horizontal rotation axis is available in the middle and upper parts zone on the same side with concave part. The hinge is mounted on the ring-shaped body support member. Pushers are available in radial slots of the ring-shaped body. The pushers are engageable with the upper part of the spatulas on one side and with mechanism for making their radial movement on the other side.

EFFECT: accelerated and simplified surgical intervention method.
