Abstract: A powered surgical tool (20) including a handpiece (24) including a motor and a battery and control module (21). The battery and control module includes a module housing (22) having a recess (34) for removably receiving the handpiece, the module housing defining a void space. A rechargeable battery module is disposed in the void space, the rechargeable battery module having a plurality of faces. A first printed circuit board (104) and a second printed circuit board (108) are disposed in the void space. The second printed circuit board is coupled to the first printed circuit board and arranged in a stacked configuration. The first printed circuit board and the second printed circuit board are both positioned on a same side of the rechargeable battery module. A controller is mounted to one of the printed circuit boards and configured to regulate power drawn from the rechargeable battery module based on user input.

Abstract: An optical sensor system for detecting a tissue type in a surgical procedure is described. The optical sensor system includes an excitation source configured to selectively emit excitation light, a probe comprising at least one fiber coupled to the excitation source and configured to illuminate target tissue with excitation light and collect light from target tissue, a compliance member coupled to the at least one fiber, the compliance member being at least partially translucent and configured to deform in response to engagement by a surgical tool, an indicator element configured to emit light in response to receiving an indicator signal, an optical detection module coupled to the at least one fiber and configured to generate a signal based on the collected light, and a controller configured to determine a tissue characteristic based on the signal and generate the indicator signal based on the determined tissue characteristic.

Abstract: A surgical tool may move a saw blade in a sagittal plane. The saw blade has a distal blade end with teeth. The surgical tool comprises a handpiece body and a carrier operatively attached to the handpiece body. The carrier is configured for oscillating movement about a pivot axis. A retainer is operatively attached to the carrier for concurrent movement and releasably secures the saw blade in the sagittal plane relative to the handpiece body. An actuator is coupled to the handpiece body to selectively oscillate the carrier relative to the handpiece body such that the retainer and the saw blade pivot back and forth about the pivot axis within the sagittal plane. An ultrasonic transducer is operatively attached to the handpiece body to selectively generate ultrasonic energy to resonate the saw blade such that the teeth at the distal blade end reciprocate proximally and distally within the sagittal plane.
