Abstract

The invention provides an operating device and relates to the field of mechanical equipment. The operating device is used for operating surgical forceps, the surgical forceps comprise a shell, a forceps core and a piston rod, wherein the forceps core and the piston rod are arranged in the shell, the forceps core can be controlled to open and close by axial movement of the piston rod, the operatingdevice comprises a base plate and a fixing device, a rotating and driving component and an opening and closing control component which are arranged on the base plate, wherein the shell is coaxially connected with the fixing device; the fixing device can drive the shell to rotate axially; and the rotating and driving component is used for driving the fixing device to rotate axially, and the opening and closing control component is used for driving the piston rod to move axially. According to the invention, two degrees of freedom ofangular rotation and opening and closing of the surgical forceps can be controlled by using the operating device, and the two degrees of freedom do not influence each other, and can be controlled independently or jointly, so that the operating device is more comprehensive in function and wider in application scenes.

Description

technical field [0001] The present invention relates to the field of mechanical equipment, in particular to an operator. Background technique [0002] Ophthalmic surgery has clinical difficulties such as fine operation, long learning curve, limited operating field and operating posture under the microscope. In order to improve the accuracy and efficiency of surgical operations, some mechanical devices are often used to assist in the operation, so as to achieve the purpose of breaking through the physiological limits of manual operation and perception, reducing the difficulty of operation, and reducing iatrogenic injuries. [0003] Ophthalmic surgical tweezers are frequently used surgical tools in ophthalmic surgery. The existing mechanical devices for operating ophthalmic surgical tweezers can only move in a single direction by holding the surgical tweezers with robotic hands. The control accuracy is low, and doctors need to Operate the opening and closing of the surgical f...
