RADIOMANIPULATING INSTRUMENT FOR DISPLACEMENT OF ABDOMINAL VISCERA IN LAPAROSCOPIC OPERATIONS Russian patent published in 2008 - IPC A61B17/02 

FIELD: medicine.

SUBSTANCE: radiomanipulating instrument for displacement of abdominal viscera in laparoscopic operations contains tubular case with handle and leaf-type retractors on working side. Retractors are opened on the axis using push bar with handle. The case has window with tray on the working side to let the retractor leaves out from the case under adjustable pitch to the case. Push bar is located in the case connected by an axis with the track carrying the leaf-type reactors and back ends on the axis. Tube is located inside the case. It has window to allow passage of the retractor back ends with V-shaped edges and stop block to put the back ends in a package and to open outermost leaves. The outermost leaves are displaced in relation to the back ends by the angles of their opening. Turning handle is mounted on the tube on the opposite working side. The handle is connected with the housing by threading. The case controls the back ends stop block position and the pitch of leaves in relation to the housing. Tube with window is located inside the tube with stop block on the working side. It ensures passage and hold-down of the back ends to the stop block and putting in a package by the V-shaped edges of window. The window edges are located toward the V-shaped edges with a stop block. Turning handle is mounted on the tube on the opposite working side. The driving handle is connected with the tube by threading. The tube has a stop block in the window and controls hold-down of the back ends to the stop block locking the leaves position. In result, radiomanipulating instrument provides the opportunity of displacement of abdominal viscera in laparoscopic interventions, provision of working space in the operation field, as well as provides the opportunity to perform laparoscopic operations without carboxypneumoperitoneum. The radiomanipulating instrument provides accurate manipulating of the retractors and fixing of the selected retractor position with adjustable pitch of the leaves using the handles located on the opposite working side of the housing.

EFFECT: reduction of traumatizing of organs located in intervention area and reduction of operation time.
