Abstract: A bone cutting device, such as a burr or saw blade, is irrigated to cool not only the bone cutting device itself, but also the bone of the subject on which a bone resection procedure is being performed. The bone cutting device can have one or more (e.g., a plurality of) internal flow channels that eject a cooling medium (e.g., water or an inert gas) from the bone cutting device. This emission of the cooling medium can not only flush bone chips from the resection site, thereby reducing frictional heating of the bone cutting device, but can also provide internal cooling to the bone cutting device while flowing through the one or more internal flow channels and also can cool the surface of the bone via conductive heat transfer (e.g., by the flow stream of the cooling medium impinging on the bone surface).

The one or more force indicators may be attached to the insertion tool and the handle. The insertion end of the device may be inserted into a joint during a surgical procedure and used to apply a force to the joint and/or measure the force using the one or more force indicators when the force is applied.

Abstract: Methods and systems of placing a medical fastener at a predetermined depth in a bone are described. A surgical tool can include an attachment assembly configured to interchangeably engage a medical fastener and a cutting element or bone removal tool and a drive assembly coupled to the attachment assembly. The attachment assembly can be configured to automatically release the medical fastener in response to the drive assembly reaching its end or distal-most position to place the medical fastener at a predetermined depth within the bone.

Abstract: Trial implant components or inserts (105), bone preparation tools (750), and methods for using same to determine bone characteristics and bone preparation processes for differentially preparing bone regions for cementless implants based on bone characteristics are disclosed. For example, in any preceding or subsequent example, a trial implant component may be configured as a bone property measurement trial implant configured to be inserted within a joint to determine measurement trial information of a bone in forceful contact therewith. In another example, operating characteristics of a bone preparation tool (e.g., voltage, torque, and/or the like) in contact with a patient bone may be measured. The measurement trial information or operating characteristics may be converted to bone characteristic information, such as bone hardness. The bone characteristic information may be used to determine, inter alia, whether a cementless implant may be supported and/or a bone preparation process for an implant.

Abstract: A robotically controlled laser resection device is disclosed. The device is configured in a handheld form factor. The device includes a treatment laser configured to generate a treatment laser beam, a laser scanner configured to direct the treatment laser beam, a water nozzle configured to emit a laminar waterjet, and an aperture configured to emit the treatment laser beam within the laminar waterjet. The components may be contained in a housing with electromagnetic shielding. A tracking marker is attached to the housing to allow navigation of the device.

Abstract: Surgical methods and devices that facilitate anatomical resection are disclosed. In some examples, a surgical resection device is disclosed that includes a static housing and a resection tool coupled to the housing via a flexible gasket that allows relative motion between the static housing and resection tool. A motor is also coupled to the static housing and is configured to rotate the resection tool about a first axis. The surgical resection device also includes two linear actuators disposed within a handle and coupled to the static housing via respective pinned linkages. The actuators are independently drivable to translate the resection tool within a second axis and rotate the resection tool about a third axis. A surgical computing device can track the surgical resection device, drive the motor and actuators to align the resection tool with a resection plane determined preoperatively, and control a position and speed of the resection tool.

Abstract: A surgical resection device may include a handle, a first blade tip, and a second blade tip stacked on the first blade tip and configured to resect bone in conjunction with the first blade tip. A surgical resection device may include a blade body, stationary with respect to the handle, moveably interfaced to the first blade tip and second blade tip, and dimensionally configured to enter a resection formed by the first and second blade tip. A surgical resection device may include one or more actuators located within the handle and configured to oscillate the first blade tip and the second blade tip, wherein when the first blade tip is at a first apex position, the second blade tip is at a second apex position, and wherein when the first blade tip is at the second apex position, the second blade tip is at the first apex position.
