A surgical tool system including a tool unit and a first battery and control module and a second battery and control module. The tool unit includes a power generating unit and a head for supporting an energy applicator. The first battery and control module is configured to releasably receive the tool unit. The first battery and control module having a first shape so that when the tool unit is attached to the first battery and control module, the tool unit and the first battery and control module have a pencil-grip configuration. The second battery and control module is also configured to releasably receive the tool unit. The second battery and control module having a second shape so that when the tool unit is attached to the second battery and control module, the tool unit and the second battery and control module have a pistol-shaped configuration.

Provided is an osteotome handpiece that may be driven by compressed gas. In an embodiment, a spherical piston may be movable inside a cylinder having a liner, which may be made of a low-friction material such as a fluoropolymer. The spherical piston may impact a blade holder that transmits force to a blade. A piston return spring may be provided, along with a piston washer to avoid any possible outward deformation of the spring. The blade holder may be retained by a split and threaded retaining collar. Single-stroke or multi-stroke operation may be chosen by the user. The device has long-operating low-maintenance advantages.

An orthopedic broach is disclosed. The orthopedic broach includes a cutting tip and a broach handle. The broach handle includes a lever, a spring, and a latch. The lever is movably coupled to the handle and to an end of the spring. The latch is movably coupled to the handle and the opposite end of the spring. In use, the lever is movable from an opened position, where the latch is positioned in a released position, so that the cutting tip can be inserted into the handle, to a closed position where the latch is moved to an engaged position wherein the cutting tip is securely coupled to the latch, and thus the handle. The handle includes a spring stop to prevent the spring from further deflection to prevent the latch from moving to the released position and thus prevent decoupling of the cutting tip when excessive forces are applied.

Systems, apparatus, and methods may be adapted for grafting tissue at a tissue site that may include an elongate housing and a plurality of elongate cutting members. The plurality of elongate cutting members may define a cutting surface at a distal end of the elongate housing. The cutting surface may be adapted to contract from a first diameter to a second diameter that is less than the first diameter. The contraction of the cutting surface from the first diameter to the second diameter may define a tapered profile between the first diameter and the second diameter suitable for obtaining a tapered graft.

A rotary mill is disclosed comprising a body portion (4) having a milling surface (10) and a central bore (30) extending along an axis of rotation (18) of the body portion (4), and a guide portion (6) having a guide body (22) and a guide peg (24) extending from the guide body (22), the guide peg (24) operable to be received in the central bore (20) of the body portion (4), the guide body (22) having at least one alignment feature (28, 30) which is the same as that of a prosthesis component. A method of implanting a unicondylar femoral component is also disclosed, the method comprising, a) reaming the femoral condylar surface to accept the unicondylar femoral component; b) drilling peg holes for affixing the unicondylar femoral component; c) affixing a guide portion of a rotary mill onto the prepared condylar surface using the drilled peg holes; d) reaming a portion of bone anterior to the affixed guide portion; e) removing the guide portion from the bone; and f) affixing a unicondylar femoral component to the prepared condylar surface.

A battery and control module to which a powered surgical tool is releasably attached. Internal to the module there is: a cell for energizing the tool; a sensor for monitoring an operational state of the tool; a sensor for monitoring a trigger external to the module; and a control circuit. Based on the signals output by the sensors, the control circuit selectively applies energization signals from the cell to the power generating unit internal to the surgical tool. In some versions of the invention, the trigger is attached to the module.

A handle assembly is disclosed for firmly holding a surgical tool. The handle assembly comprises a handle and a locking mechanism attached to the handle. The locking mechanism includes a locking ring, a collet, and a compressible locking pin engageable with the locking ring and collet. The locking ring is moveable between first and second positions relative to the handle. The first position is an unlocked position whereby the locking pin is in a decompressed state relative to the locking ring and the collet. In the first position, a surgical tool may be inserted and withdrawn from the collet of the locking mechanism. The second position is a locked position whereby the locking pin is in a compressed state relative to the locking ring and the collet. In the second position, a surgical tool is anchored in the collet of the locking mechanism.

A decompression surgery system includes an instrument shuttle configured to engage a first side of a target anatomical location, the instrument shuttle including a track. The system further includes a working channel configured to couple to and advance along the track of the instrument shuttle, the working channel having a distal end configured to engage a second side of the target anatomical location so that the target anatomical location is positioned between a portion of the instrument shuttle and the distal end of the working channel. The working channel is configured to receive one or more instruments therethrough.

An intraosseous needle set comprising a cannula is provided. The cannula has a first end, a second end, and a bore configured to receive a sample from a target area. The first end of the cannula is configured to penetrate the target area and has a plurality of teeth. The plurality of teeth may have at least one tooth that comprises a tapered surface. The plurality of teeth may each have a first side and a second side, where a length of the first side is less than a length of the second side. The first and second sides may intersect to define tips that are disposed at an angle between 0 and 30 degrees relative to a longitudinal axis of the cannula, and the first side of a first tooth and the second side of an adjacent tooth may also intersect at an angle between 55 and 80 degrees.
