The invention relates to an assembly for use in minimally invasive surgical procedures, including bone implant fixation procedures. The assembly is configured to provide a faster and more accurate measurement of depth of holes for placement of bone screws and fasteners. The assembly includes a guidewire having a deployable distal hook member configured to securely anchor into a desired position relative to a hole drilled in a bone and thereby provide an accurate datum for a measuring instrument for determining a depth of the hole for subsequent screw placement. The assembly further includes a surgical depth instrument to cooperatively function with the guidewire and obtain one or more measurements while operably coupled to the guidewire.

A method comprises the steps of: fixing a distal end of a first member of a surgical instrument with tissue, the surgical instrument including a second member having a longitudinal passageway configured for disposal of the first member and being connected with a navigation component such that the distal end is disposable with the passageway at a selected distance from the navigation component, the navigation component being positioned relative to a sensor to communicate a signal representative of an orientation of the first member; removing the second member from the first member; and connecting a third member with the first member along the orientation such that a distal end of the third member is fixed with the tissue. Systems, spinal implants, constructs and instruments are disclosed.

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.

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.

A system to measure and display the orientation of a handheld instrument is disclosed.

Bone anchors and surgical instruments (e.g., bone taps, drivers, etc.) are disclosed herein that include integrated guide tips. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. For example, a surgical instrument can include a guide projection configured for insertion through a cannulation formed in a bone anchor when the surgical instrument is coupled to the bone anchor. The surgical instrument can also include various mechanisms for adjusting the position of the guide projection relative to the bone anchor. The guide projection can replace the needle, stylet, and guidewire used in typical insertion procedures. The bone anchor can also include integrated tapping features to eliminate the need for a separate bone tap instrument. Thus, in some embodiments, targeting, tapping, and driving the bone anchor can be performed in a single step.

The invention relates to a surgical tool and method for forming a pilot bore by inserting a guide wire into bone. The surgical tool is also constructed to insert a bone screw that is preloaded onto the surgical tool with a guide wire extending along the longitudinal axis of the bone screw. This construction allows the guide wire and the bone screw to be located and placed without removing the tool from the surgical site. More particularly, the device includes a cannulated hand grip and driving tool used for the rotation of a pedicle screw into bone. The rear portion of the hand grip includes a slide assembly that is suited to grip a guide wire. The slide assembly includes a T-handle to control the sliding movement of the guide wire. The rear surface of the slide is constructed to be impacted with a hammer or similar device.

An apparatus is disclosed for use with an electronic device for alignment of a medical tool for positioning a surgical hardware device. The apparatus includes a case to secure the electronic device such that the electronic device is secured to the case and does not move relative to the case. The case includes an opening to couple with at least a portion of the medical tool. The electronic device is secured relative to the medical tool through the coupling of the case to the at least the portion of the medical tool. The electronic device simulates a three-dimensional position of the surgical hardware device in a body using a diagnostic representation of at least a portion of the body, and the electronic device is secured in the case and coupled to the medical tool assists with the alignment of the medical.
