Surgery device and operating method using the same

A surgical device system, comprising:

• a surgical instrument comprising a surgical instrument module having a surgical tool for performing surgical operations, wherein
• the surgical instrument module comprises a first side and a second side opposite the first side, and the surgical instrument further includes
• a dual parallelogram module coupled to the second side of the surgical instrument module, the dual parallelogram module having at least one power transmission unit for providing movement;
• and
• a linear driving module coupled to the at least one of the power transmission unit, a holder disposed between the at least one power transmission unit and the surgical instrument;
• and
• a pre-load part disposed on the holder and rotatably connected to the at least one power transmission unit;
• a power source module operably coupled to the surgical instrument for providing power to the surgical instrument;
• and
• a communication module integrated within the surgical instrument, the communication module configured to establish wireless communication between the surgical instrument and an external controller;
• wherein
• the linear driving module transmits a driving force to the dual parallelogram module,
• the dual parallelogram module has at least two degrees of freedom
• the surgical instrument is operably coupled to the holder,
• the pre-load part is configured to press a coupling shaft that rotatably connects the holder to the at least one power transmission unit, and
• the external controller comprises a user interface application, wherein the user interface application is configured to receive and process data transmitted from the surgical instrument device system via the communication module, and present visual feedback and control options to a user.

A method of operating a surgical device, the method comprising:

• providing a surgical instrument module having a surgical instrument coupled to a first end and a dual parallelogram module coupled to a second end, the dual parallelogram module comprising at least one power transmission unit;
• providing a linear driving module coupled to the at least one power transmission unit;
• providing a holder disposed between the at least one power transmission unit and the surgical instrument, and a pre-load part disposed on the holder and rotatably connected to the at least one power transmission unit,
• actuating the linear driving module to transmit a driving force to the dual parallelogram module such that the surgical instrument performs at least one of a first driving motion, a second driving motion, or a third driving motion, and
• pressing a coupling shaft that rotatably connects the holder to the at least one power transmission unit.
