ROBOTIC SURGICAL SYSTEM Russian patent published in 2021 - IPC A61B34/30 

FIELD: medical equipment.

SUBSTANCE: invention relates to medicine, namely to robotic surgical systems. The system is comprised of a manual unit including a rigid casing and an electric engine assembly inside the casing. The casing consists of a body and a handle. The body part includes a tip. The electric engine assembly comprises: a frame, a first and second pairs of electric engines, a drive roller, a friction gear, a friction gear ring, two drive rods, a secondary roller, a drive belt, two drive rings, control electronics, a control mechanism, a mode switching mechanism and a connector for connecting a power source to supply power to the control electronics and electric engines. Each of the electric engines has a body attached to the frame. Each electric engine from the first pair has a drive shaft extending from the body of the electric engine in a first direction. Each electric engine from the second pair has a drive shaft extending from the body of the electric engine in a second direction opposite to the first direction. The drive roller is connected with the drive shaft of each electric engine. The friction gear comprises a roller connected with the drive roller by the drive belt. The secondary roller is connected with each of the drive rods. The drive belt connects each secondary roller with the drive roller. Each drive ring is driven by one of the drive rods. The control mechanism is connected with the control electronics and passes through a hole in the casing. The mode switching mechanism is connected with the control electronics and passes through a hole in the casing. The system also comprises a mechanical manipulator connected with the manual unit. The mechanical manipulator has four degrees of freedom.

EFFECT: reduced size of the robotic surgical system is achieved.
