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.

Embodiments of a compliant orthopedic driver are disclosed herein. In some embodiments, compliant orthopedic driver includes a body extending from a proximal end to a distal end along a driver axis; a driver tip disposed at the distal end of the body, wherein the body includes at least one compliant portion configured to allow the driver flex about at least two axes transverse to the driver axis.

The present invention discloses fusion systems and methods of assembly and use. The fusion systems include a first fastener, a second fastener, and an elongate member with a first end and a second end. The first end being secured to the first fastener and the second end being secure to the second fastener. The method of assembling a fusion system and methods of using the fusion systems are also disclosed.

A surgical polygonal locking screw removal device includes: a body including a passage part in which a passage having a preset diameter is formed, and a polygonal expansion part configured to be coupled to a polygonal groove formed in a surgical locking screw to remove the surgical locking screw, the polygonal expansion part protruding from a leading end of the passage part; and a handle configured to be inserted into a rear end of the passage part and screw-coupled to the passage part, and configured to expand the polygonal expansion part.

A bone screw extraction device includes a shaft extending longitudinally from a proximal end to a distal tip, a distal portion of the shaft including a tissue-receiving cavity extending proximally thereinto from the distal tip, the distal tip including a plurality of fingers configured to be received within a driving recess of a bone screw and a plurality of channels extending longitudinally along an exterior surface of the distal portion, each of the plurality of channels extending between adjacent ones of the plurality of fingers.

A surgical tool adaptor includes a distal interface member and a proximal holder. The surgical tool adaptor is formed with a lumen through the distal interface member and the proximal holder for passing a guiding element (e.g., K-wire) distally through the distal interface member. The proximal holder includes a locking element for locking the guiding element in the lumen and the distal interface member includes a connecting element for connecting to a surgical tool. The proximal holder is movable relative to the distal interface member so that the proximal holder is movable to a position wherein the guiding element does not protrude proximally out of the proximal holder.

A dental fixture operation connector is disclosed. The dental fixture operation connector may include a connector body portion, a connector head portion connected to the connector body portion and inserted into an insertion hole formed in an upper end area of a fixture, and an entrance guide portion provided in the connector head portion and guiding entrance of the connector head portion when the connector head portion is inserted into the insertion hole.

A system for manipulating a rotational device using a flexible guide rod with an external rod feature along its length to engage a rotational device with a complementary interior channel feature along its length. A driver having a handle and coupling element is coupled to the rotational device while the flexible guide rod extends from the handle, through the coupling element, and into the interior channel of the rotational device in order to rotate from within along the length of the device.
