The alignment rod is sized and configured to extend into the interior passageway thereby allowing the locking pin to extend into the interior passageway to secure the alignment rod.

The guide rod (24) is couplable to a second end of the alignment rod (4) at an adjustable angle and orientation such that the guide rod (24) can extend transverse to the alignment rod (4).

The alignment rod (4) has a first end pivotally coupled to the mount (2) such that the inclination of the alignment rod (4) relative to the mount (2) is adjustable.

Other embodiments include an alignment feature (31, 190, 192) which may be, but not limited to, a bar code (192), an alignment pin (31), an alignment slot or a keyed corner (31).

A surgical instrument alignment guide comprising a mount (2) arranged to be coupled to a bone of a patient, an alignment rod (4), a guide rod (24) and an indicator (26).

The device also includes an alignment pin assembly which can be selectively manually or automatically advanced.

At least one trackable member is mounted to the alignment rod of the tool and is in communication with the computer assisted surgery system for providing at least orientation information of the alignment rod.

The guide assembly includes a support plate attachable to the mobility device and an alignment rod whereby the alignment rod extends out from one side of the mobility device and engages the receiving member.

The rear housing part (16) has a receptacle opening (76) for the orientation pin (74).

The cutting block, or the alignment rod towards its proximal end, has fixation holes for receiving fixation pins, to fix the cutting block and the alignment rod against further movement relative to the guide pin.

The tool includes upper and lower mounting ends interconnected by an alignment rod extending therebetween.

In one aspect, an optical fiber connector includes a multilens array and at least one alignment post.

The alignment rod has a diameter D1 and protruded from the mating surface a protrusion distance p1, wherein p1 ≤ 2D1.

An instrument block body (16) can slide upon the alignment rod (11) between its end portions (12, 13).

The first biasing member is capable of being biased to cause an alignment pin of a ferrule to open a door of the retractable shroud.
