Rapid alignment mechanism for surgical instrument box and power box

Abstract

The invention relates to a quick alignment mechanism for a surgical instrument box and a power box, which comprises the power box and the instrument box, a lower clutch disc on a front cover plate of the power box corresponds to an upper clutch disc on the instrument box, and a notch of the upper clutch disc is completely embedded with a bulge of the lower clutch disc; a positioning pin and a guide buckle are arranged on the front cover plate; the positioning pin and the guide buckle are respectively inserted into the pin hole and the buckle groove of the instrument box; a driving motor is installed in the power box, an output shaft is installed at the output end of the driving motor, and the lower clutch disc slides front and back along the output shaft. The front section of the output shaft is provided with a compression spring, and the compression spring provides reset force when the lower clutch plate is pushed towards the driving motor by external force, so that the lower clutch plate is jacked back to the original position by the compression spring when the external force disappears, and the lower clutch plate is driven by the motor to rotate to be embedded with the upper clutch plate to realize rapid alignment; rapid alignment and rapid installation of a replaced instrument in the operation process can be achieved, and the device is simple in structure, high in reliability, low in cost and easy and convenient to operate.

Description

[Technical field] [0001] The invention relates to the technical field of surgical robots, in particular to a rapid alignment mechanism for a surgical instrument box and a power box. [Background technique] [0002] With the development and progress of science and technology, minimally invasive surgical robots have been accepted by more and more hospitals and doctors around the world, and are used in various clinical surgical operations. In the process of robotic surgery, it is often necessary to replace various surgical instruments to complete operations such as clamping, cutting, suturing, knotting, etc., but the power box used to drive the movement of surgical instruments usually does not need to be replaced and is fixed at the end for operation. on the arm. Therefore, realizing rapid replacement of surgical instruments is an important function of minimally invasive surgical robots. The point of quick replacement is that the surgical instrument box and the power box shoul...
