Abstract: A surgical handpiece system for performing measurement functions and surgical operations. The system includes a handpiece assembly. The handpiece has a handpiece housing and a drive cannula rotatably coupled to the handpiece housing. The drive cannula extends along an axis and is configured to receive torque from a motor. A surgical attachment module has an attachment housing removably coupleable to the handpiece housing. The surgical attachment module has a drive shaft rotatably coupled to the surgical attachment housing and configured to receive torque from the drive cannula to operate an end effector. A measurement module has a measurement housing removably coupleable to the handpiece housing. The measurement module is configured to perform measurement functions associated with operation of the handpiece assembly.

Abstract: A method of assembling a measurement module used for bore depth determinations in tissue. The measurement module has a housing. A gear having a plurality of gear teeth is disposed within and rotatably coupled to the housing. The measurement module further includes a bushing and a depth extension member having a plurality of rack teeth extending along a depth extension axis. The depth extension member is disposed within a bore of the bushing and the housing. The rack teeth of the depth extension member are arranged to be engaged by the gear teeth of the gear. The depth extension member is urged toward the gear so that the rack teeth are in meshed engagement with the gear teeth. The bushing is fixed to the housing while the depth extension member is urged toward the gear.

Abstract: A drill bit comprises a shank extending along an axis and an interface comprising at least one outermost drive portion spaced at a first interface distance from the axis. The drill bit further comprises a resilient arm extending from a proximal end of the shank. The resilient arm comprises an outer arm surface facing away from the axis and a retention surface facing toward a distal end of the shank. The retention surface may be radially aligned about the axis with respect to the outermost drive portion. The resilient arm is movable between: a first position where the outer arm surface is spaced from the axis at a first arm distance greater than the first interface distance, and a second position where the outer arm surface is spaced from the axis at a second arm distance less than or equal to the first interface distance.

Abstract: Systems and methods for facilitating movement of a patient transport apparatus. The patient transport apparatus has a support structure and a patient support surface. Caster assemblies are coupled to the support structure to roll about a roll axis and swivel about a swivel axis. A control system is configured to control brake mechanisms, steer-lock mechanisms, and pre-swivel mechanisms of the caster assemblies based on one or more inputs.
