20190374295 | Apparatus And Methods For Robot Assisted Bone Treatment - A method for performing a surgical procedure includes planning a resection of a bone of a patient. A volume of the bone is removed according to the planned resection using a surgical tool. As the bone is removed, data corresponding to a shape and volume of the removed bone is tracked with a computer system operatively coupled to the surgical tool. A prosthesis is implanted onto the bone of the patient based on the tracked data corresponding to the shape of the removed bone. | 2019-12-12 |
20190374296 | SURGICAL TABLE BASE CONSTRUCTION FOR HEAT DISSIPATION FROM HOUSED POWER ELECTRONICS - Some embodiments described herein relate to a surgical table, specifically a base of a surgical table. The surgical table can be adapted to include and/or be coupled to a surgical robot. The base of the surgical table can form an enclosure including a cover and a bottom. Electronic components (e.g., power electronics associated with the surgical robot) can be disposed within the enclosure. In some embodiments described herein, the cover of the base of the surgical table can be constructed of aluminum or similar material having a thermal conductivity of at least 200 W/m K. In some embodiments described herein, a side wall of the base of the surgical table can be constructed of aluminum or similar material having a thermal conductivity of at least 200 W/m K. Other embodiments described herein describe various other solutions for thermal management of electronic components. | 2019-12-12 |
