TODAY’S PATENT – A SURGICAL INSTRUMENT FOR USE WITH DIFFERENT CARTRIDGES

The said invention (US11071844B2) was invented by David C. Yates, Frederick E. Shelton, IV & James R. Giordano. It was patented by USPTO on July 28^th, 2020. Currently, it stands assigned to Cilag GmbH International.

This invention concerns surgery tools for cutting and attaching things, especially endoscopic and laparoscopic tools. It has some special features, like a portable motor that runs on a DC power source with cell selection for motor control and a power regulator for good voltage management. Rechargeable batteries or supercapacitors can be used in instruments. Power packs can be taken off and charged from a distance using remote bases, which lets data be sent for performance analysis. Damage from too much force is stopped by an inbuilt torque-limiting device.

RF tools use new electrode arrangements with smaller active electrodes and bigger return electrodes. This improves tissue contact and lowers the heat effect. Sequentially triggered split wires lower the power needed and make the system more reliable. The tools can also talk to robotic systems. The end effector is powered by a DC motor that is connected to a drive train. These improvements make surgeries safer, easier to control, and more effective.
