A self-contained hand-held through-skin (HHTS) sensor for determining the location of an underlying aperture in a support structure suited to mount a skin or surface. In an embodiment, the HHTS sensor includes a sensor disposed in a housing and configured to determine a location of an aperture disposed in an adjacent surface through electromagnetic, x-ray, ultrasonic or other means. The HHTS sensor further includes an alignment assembly having an alignment orifice disposed in the housing and configured to be maneuvered in an x-y plane within the housing. The HHTS sensor also includes a vacuum pump system, a local battery and a processor coupled to the sensor and configured to control first and second actuators to maneuver the alignment orifice within the x-y plane to be co-axially located with the aperture in response to the sensor signal.

Device for making a hole in a workpiece, including a drilling tool, a supporting apparatus that is or can be assigned to the drilling tool and is configured for supporting the drilling tool on at least one supporting region, wherein the supporting apparatus includes an elongate main body that includes at least two main-body elements, at least one main-body element being mounted so as to be movable relative to at least one additional main-body element in order to change the length measurement of the main.

A method for operating an electric core drilling machine, in particular a magnetic core drilling machine, comprising the steps: identification of a core drill bit detachably connected to the core drilling machine, by means of an information carrier associated with the core drill bit and an information receiver associated with the core drilling machine; detection of a load quantity of the core drill bit; determination of a wear value of the core drill bit on the basis of the value of the load quantity; issuance of an error value when the wear value exceeds a wear limit value; as well as issuance of a signal to indicate the necessity of replacing and/or repairing the core drill bit. In addition, the invention relates to a core drilling machine and a core drill bit for carrying out the method.

A work machine unit includes: a support member assembled to an end effector connection part of an operating machine; a work machine part assembled to one end of the support member; and a linear guide disposed at another end of the support member across its connection to the end effector connection part from the support member, arranged in parallel to an axial direction of the work machine part, and configured to abut against a work object or its peripheral structural object. Further, the linear guide is passed through a through-hole formed in the support member, and the support member is configured to move in the axial direction of the work machine part as guided by the linear guide.

The current invention provides apparatus and a method for use with a drill bit to form a hole in a workpiece, said apparatus including a clamping means to clamp a workpiece in which the hole is to be formed in position with the apparatus, a drill bit holder assembly and drive means for rotating the drill bit and moving the same into the workpiece so as to drill the hole at a required angle and depth into the workpiece. Typically the depth of the hole is set in relation to the thickness of the workpiece which is clamped in position at that time and the apparatus includes a first part which is held by a first hand of the user and movable by the user with respect to a second part which is held by a second hand of the user and the relative movement is translated into movement of the drill bit holder to move the rotating drill bit into the workpiece.

A device configured to provide a faster and more accurate measurement of depths of holes for placement of bone screws and fastener for bone implant fixation procedures. The device includes a combination of a bone probe for physical examination of a hole drilled in a bone and a depth gauge member for determining a depth of the hole and providing digital measurement of the depth via a display on the instrument and/or via a wireless exchange of measurement data to a remote computing device, such as a tablet or smartphone. The device may further be connected to a separate neuromonitoring device and be used for nerve sensing and/or nerve stimulation by way of the bone probe. For example, the bone probe may include a conductive material such that the distal probe tip acts as an extension of the neuromonitoring device and may be used to sense and/or stimulate nerves.
