The invention is directed to a system and device for separating and collecting a tissue specimen from a target site within a patient. The device includes a probe component with an elongated tubular section, a penetrating distal tip and a tissue receiving aperture in the distal end of the tubular section proximal to the distal tip, and a tissue cutting member which is slidably disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture by applying a vacuum to the inner lumen of the tissue cutting member. The device also has a driver component to which the probe component is releasably secured. The driver has a drive member for adjusting the orientation of the tubular section and thus the aperture therein and one or more drive members for moving the tissue cutting member within the tubular section to sever a tissue specimen from tissue extending into the interior of the tubular section through the aperture. The motion imparted to the tissue cutter is at least longitudinal and preferably is also oscillation and/or rotational to effectively separate a tissue specimen from tissue extending through the aperture in the tubular section.

A power saw includes a bevel member and a cutting assembly pivotably connected to the bevel member. The cutting assembly includes a blade, a blade guard at least partially covering the blade, and at least one machined cutting assembly surface. A laser alignment device is connected to the cutting assembly. The laser alignment device includes a laser body fixed to a slideable carriage having a machined carriage surface that directly engages the machined cutting assembly surface. The slideable carriage is configured to move relative to the machined cutting assembly surface with substantially only one degree of freedom defined by an axis of translation.

A laser projector assembly for projecting a template onto an object is provided. The laser projector assembly includes a frame, a laser source for generating a laser beam being affixed to said frame, a sensor assembly, a lens assembly and a galvanometer assembly. The sensor assembly is affixed to said frame for identifying surface locations of three dimensional objects. The lens assembly includes a tunable lens for changing a focus of the laser beam received from said laser source. The galvanometer assembly redirects the laser beam received from said lens assembly along a scanning path. The lens is disposed in a fixed location relative to said sensor assembly and is tunable in response to the surface locations of the three dimensional objects identified along the scanning path of the laser beam by said sensor assembly.

The invention is directed to devices and methods for separating and collecting a tissue specimen from a patient's target site. The device includes a probe member with a penetrating distal tip and a tissue receiving aperture, and a tissue cutting member which is rotatable disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture. The longitudinal edges of the aperture are preferably sharpened to engage the cutting edges of the tissue cutting member. Vacuum may be provided in the inner lumen of the cutting member to transport tissue therethrough. Rotation, rotational oscillation and/or longitudinal reciprocation of the tissue cutting member is effective to separate a tissue specimen from surrounding tissue. An accessing cannula having an tissue receiving aperture may be concentrically disposed within the probe member and about the tissue cutting member. The tissue cutting edge of the tissue cutting member preferably is longitudinally oriented and may have a cutting angle less than 90 with respect to the longitudinal axis of the tissue cutting member.

The present disclosure relates generally to a tool that facilitates machining of inserts mounted in a primary component. More specifically, tools according to the present disclosure may be designed to support removal of recessed inserts in primary components without damaging the underlying primary components.

A power tool (e.g., a pneumatic tool) includes a tool housing, a motor disposed in the tool housing, and a switch coupled to the tool housing and configured to control operation of the motor. A light unit includes a light unit housing removably coupleable to the tool housing. The light unit includes a light disposed in the light unit housing, a controller, and a sensor. The sensor is configured to sense actuation of the switch, and the controller is configured to cause the light to turn on when the sensor senses that the switch is actuated.

A machining swarf detection apparatus that detects presence or absence of machining swarf in a machining chamber of a machine tool includes an illumination unit that illuminates line laser light onto a detection area in the machining chamber, an imaging unit that images the detection area and acquires an image as an inspection image, and an image processor (controller) that detects the presence or absence of the machining swarf based on an image of the line laser light imaged in the inspection image.

An illustrative embodiment of the present disclosure provides hand-held power tool which includes a housing, a motor, and an output spindle. The housing supports a motor having a rotor configured to rotate when the motor is supplied with power. The output spindle protrudes from an output end of the housing, and is functionally coupled to the rotor such that the output spindle rotates in response to a rotation of the rotor. The housing also supports at least one electrical accessory that is connectable to an external power connector located on the housing.

A tool storage system includes a tool storage container configured to receive therein a battery for a power tool with an inductive receiving unit. An inductive transmitting unit is coupled to the tool storage container and configured to receive a source of electrical power. The inductive transmitting unit is configured to induce generation of electrical power in the inductive receiving unit to charge the battery. A controller is configured to control generation of electrical power by the inductive receiving unit based on a position or alignment of the inductive receiving unit relative to the inductive transmitting unit.
