In aspects, a sensor is disposed on a distal face of the retractable shield. In aspects, a surgical system including the surgical cutting device includes control circuitry configured to receive sensed data from the sensor and to provide an output based thereon.

Abstract: Disclosed is a system to engage one or more tools. In the system a drive shaft and collet may be assembled to engage and disengage, selectively, a plurality of tools. Further, a tracking device may be used to track a location of at least a portion of the tool.

Abstract: Surgical tracking, methods and software for assisting in determining whether a tool is properly installed on a surgical device. A protective packaging retains the tool and has a trackable feature. The trackable feature has a predetermined state defined relative to the tool and the trackable feature is detectable by a machine vision system. One or more controllers acquire the actual state of the tool based on the detected trackable feature and compare the actual state of the tool with an expected state of the tool, which is based on an expected condition in which the tool is properly mounted to the surgical device. Based on the comparison, the one or more controllers can determine whether the tool is properly mounted to the surgical device and generate an alert.

Abstract: A surgical device includes a housing configured to receive a tool having a cylinder configured to support a drive shaft. A collar assembly is disposed atop the housing and is configured to engage a cylinder head of the cylinder. The collar assembly includes: a collar having a step ring separating an inner peripheral surface and a spring assembly seat, the inner peripheral surface dimensioned to engage the housing and the spring assembly seat configured to receive a spring assembly therein. One or more engagement spheres are configured to seat within a ball pocket defined through the housing. The sphere(s) is configured on one end to abut the cylinder head upon introduction into the housing and on the opposite end to seat within a groove defined within the collar. The sphere(s) translates within the groove between first and second pockets upon collar rotation to secure the cylinder within the housing.

Abstract: A surgical device includes a tool and a motor configured to drive movement of the tool. The tool is supported on a shaft assembly and the shaft assembly and the motor include a plurality of components that cooperate to support or drive the tool. One or more indicators are disposed proximate one or more of the plurality of components and are configured to provide feedback indicative of one or more properties of one of the plurality of components either prior to, during or after use of the surgical device. The plurality of components may include at least one of gears, shafts and bearings, and the indicators may include any one of: thermochromic indicators, thermally-activated elements, thermal fuses, thermocouples, and thermistors.

Abstract: A method for identifying a surgical tool for use with a surgical device includes integrating a variable indicator within a removably engageable component of a surgical tool of a surgical device. The method also includes engaging the surgical tool with the surgical device, wherein, upon engagement, the variable indicator aligns with one or more leads connected to a power console. The power control reads the variable indicator and identifies the surgical tool based on quantifying the variable indicator. The power control is then calibrated according to the operating parameters of the surgical tool stored within the power control.

Abstract: A surgical system having adaptive control includes a surgical cutting device, at least one sensor, and a controller. The surgical cutting device includes a cutting tool and a motor configured to drive movement of the cutting tool. The at least one sensor is configured to produce sensor data indicative of at least one property of the surgical cutting device during use. The controller is configured to receive the sensor data and determine a performance condition of the surgical cutting device based at least on the sensor data. The controller is further configured, where the determined performance condition is an adverse performance condition, to at least one of: adjust settings of the surgical cutting device or recommend a change relating to use of the surgical cutting device.

Abstract: A surgical device for cutting or shaving bone or tissue includes an outer housing having a collet secured to an inner peripheral surface thereof including one or more apertures defined therein. A housing includes an elongated tube extending therefrom configured to support a surgical tool at a distal end thereof. A gear assembly is disposed within the housing and is configured to drive the surgical tool, the gear assembly includes a drive gear housing selectively moveable within the housing to switch the gear assembly between an oscillation mode and a rotation mode for driving the surgical tool. A motor is operably coupled to the gear assembly, such that, upon activation thereof, the motor oscillates or rotates the surgical tool depending upon the position of the drive gear housing within the housing.

A gear assembly is disposed within the housing and is configured to control oscillation of the surgical tool. A motor is operably coupled to the housing and is configured to drive the gear assembly upon activation thereof. The motor is moveable relative to the housing to adjust one or more gears of the gear assembly which, in turn, adjusts an oscillation angle of the surgical tool to control the aggressiveness of the surgical tool when cutting tissue or bone.

Abstract: A drill assembly including a cutting tool slidably movable along a longitudinal axis of the drill assembly and drivable to cut an object. In an active configuration, a pressure loaded drive control assembly transfers energy from a motor to the cutting tool to drive the cutting tool. In an inactive configuration, the pressure loaded drive control assembly prevents energy transfer from the motor to the cutting tool. A biasing member of the pressure loaded drive control assembly is configured to bias the pressure loaded drive control assembly in the inactive configuration. Depressing the cutting tool against the object moves the cutting tool along the longitudinal axis and moves the pressure loaded drive control assembly to the active configuration. The biasing member returns the pressure loaded drive control assembly to the inactive configuration when the cutting tool is no longer depressed against the object.
