Interfragmentary guide and plate system
A plating system includes a bone plate including an aperture. A locking member is receivable in the aperture to attach the bone plate to a joint. The plating system includes a guide including a body having a first end portion, a second end portion, an attachment portion attached to the bone plate, and a rotating portion including a sleeve to receive a drill or a guide wire. The first end portion of the body is rotationally connected to the attachment portion to pivot the body about a first axis to move the sleeve, and the rotating portion is rotationally connected to the second end portion of the body of the guide to pivot the rotating portion about a second axis to move the sleeve. The rotating portion translates along the second axis to move the sleeve, and the sleeve defines one of a plurality of trajectories.

DEVICES AND METHODS FOR ORIENTING A SURGICAL DEVICE
Devices and methods are provided that simplify and improve placement of stabilizing orthopedic pins, wires, and/or screws in the pelvis in minimally invasive surgery. Provided is a surgical instrument guide containing an adjustable friction clamp for positioning and securing a cannula, and a probe with a blunt, nonpenetrating tip. The probe and a surgical instrument held by the friction clamp are oriented at right angles to one another. In use, the blunt probe is introduced through a small incision and advanced by blunt dissection until the blunt tip is positioned at a desired anatomical landmark on the surface of the pelvis. A cannula inserted through the friction clamp is advanced until the tip of the cannula is within 2 cm of the blunt tip of the probe; an orthopedic pin, wire, and/or screw can then be inserted through the cannula to provide stabilization. The blunt probe may be cannulated.

SURGICAL INSTRUMENT
Disclosed is an apparatus for operation that can be inserted into an incision hole in spinal endoscopic surgery. An apparatus for operation includes a rod, a rotating part rotatably connected to the rod, and a bending part connected to the rotating part and bendable, in which the bending part includes a plurality of links being in rolling contact with each other, and a plurality of wires connecting the plurality of links.
INSTRUMENT FOR USE IN SURGERY
A surgical instrument is connectable to a bone anchor insertion device having a drive shaft that defines a coaxial channel for receiving a needle therethrough. The instrument includes a handle portion configured to be coupled to the drive shaft in a rotationally fixed manner to transmit torque to the drive shaft, a needle holder configured to hold a needle and movable axially relative to the handle portion, an actuator rotatable relative to the handle portion, and a transmission member connectable to the needle holder and movable axially relative to the actuator and comprising a first advancement surface engageable with a second advancement surface of the handle portion to convert rotational movement of the actuator into axial movement of the needle holder relative to the handle portion for axially advancing and retracting a needle held by the needle holder relative to the handle portion.
IMPLANTED ARTICLE PHYSICAL REFERENCING APPARATUS
An implanted article physical referencing apparatus comprises a guide body, a first guide shaft and a second guide shaft. The guide body includes a plurality of guide shaft receptacles therein. A longitudinal axis of each of the guide shaft receptacles extends substantially parallel to a longitudinal reference axis of the guide body. The first and second guide shafts each have a proximate end portion and a distal end portion. The proximate end portion of the first guide shaft includes an exterior surface adapted for being engaged with a corresponding interior surface of a selected one of the guide shaft receptacles to constrain unrestricted relative movement between the first guide shaft and the guide body. The proximate end portion of the second guide shaft is attached to the guide body. A longitudinal axis of the second guide shaft extends substantially parallel to the longitudinal reference axis of the guide body.
TOTAL WRIST PROSTHESIS AND RELATED METHODS
A tool for locating the insertion point of a radial component of a wrist prosthesis on a human distal radius bone, the guide comprising a handle; a guide face attached to the handle, the guide face being of a shape configured to engage an articular surface of the distal radius bone; the guide face comprising three visual cues respectively adapted to align with a palmar corner of a radio-ulnar joint located on the distal radius, a dorsal corner of a radio-ulnar joint located on the distal radius, and a tip of a radial styloid located on the distal radius; the guide face further comprising an opening designating the insertion point, the opening being at a designated location on the guide face relative to the visual cues; and the opening adapted to facilitate the marking of the insertion point on the articular surface of the distal radius bone.
Device and system for facilitating insertion of a bone treatment device
A device includes an outer sleeve of flexible material forming an outer conduit extending longitudinally therethrough for the insertion of a bone treatment device (“BTD”) to target sites within a living body. A distal opening of the outer conduit is open so that, when the outer sleeve is in a desired position within the body, BTD is inserted through the outer conduit exits the outer sleeve adjacent to a target portion of a bone. The device also includes an inner sleeve received within the outer sleeve and defining an inner conduit within the outer conduit to form a protective covering. The inner sleeve is split longitudinally. Portions of the inner sleeve on opposite sides of the split are coupled to one another so that a diameter of the inner conduit is adjustable in response to forces exerted thereon by one of BTD and tissues surrounding the outer sleeve.
