Operation robot and mechanical arm thereof

Abstract

The invention provides an operation robot and a mechanical arm thereof. The mechanical arm comprises a horizontal moving joint, a first rotating joint, a connecting arm and a vertical moving joint. The first rotating joint comprises a first rotating shaft and a first outer cylinder arranged on the first rotating shaft in a sleeving mode, and the first outer cylinder can rotate around the first rotating shaft. The connecting arm is connected with the first outer cylinder and the vertical moving joint. The vertical moving joint comprises a connector and is used for driving an external component connected with the connector to move in the vertical direction. The horizontal moving joint is connected with the first rotating shaft and used for driving the first rotating joint to move in the horizontal direction. According to the operation robot and the mechanical arm thereof, the horizontal movement of the mechanical arm can be achieved through the horizontal moving joint, and the vertical movement of the mechanical arm can be achieved through the vertical moving joint; as the number of the joints is small, the structure relation is simplified, the appearance size of the mechanical arm is reduced, and the overall mass of the mechanical arm is reduced; besides, the precision of movement control is high, additional movement displacement can be avoided, and operation is easier and more convenient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a mechanical arm used for micro-trauma surgery. Background technique [0002] Minimally invasive surgery is an interventional method that uses tiny channels for surgical treatment. It uses the corresponding minimally invasive surgical instruments, which can achieve the same or better curative effect as traditional surgery. Compared with traditional surgery, micro-traumatic surgery has the characteristics of less trauma, less bleeding, and faster recovery, and has become an important direction for the development of contemporary medical technology. [0003] As a part of the minimally invasive surgery, compared with the general minimally invasive surgery, the surgery using the minimally invasive surgical robot has less pressure, more precise surgical operation, and more flexible surgical operation. Therefore, the development of micro-traumatic surgical robots has becom...
