A robotic device mounted on the head of a patient has a pivoted arm that extends down to support an article, such as a part of the jaw of the patient in orthognathic surgery. The pivoted arm is on a support plate that is in turn supported by a hexapod assembly that connects with a U-shaped bracket secured to the patient's head. The hexapod is computer controlled to adjust the position of the support plate relative to the head of the patient to precisely locate the supported article on the patient, such as where a separated portion of the patient's jaw is positioned for reattachment in orthognathic surgery.

A head frame apparatus is secured to a human head during maxillofacial surgery and includes devices to easily position and secure an endotracheal (breathing) tube and an anesthesia delivery circuit for the patient that reduces the likelihood that the flow of oxygen through the tube is restricted thereby reducing the risk of severe injury or death. The head frame apparatus also includes a removable reference indicator, which may be easily attached and removed while identifying a reference point of the patient's face. Also the reference indicator includes a universal joint and pointer with an attached ruler. A transport apparatus positions multiple preset reference indicators and allows for preoperative transportation and removal, while protecting the preset reference indicators from inadvertent adjustment. A bendable reference indicator used in an articulator for preoperative modeling allows for easily identifying reference points in a cast model. An orbiting segment apparatus positions a portion of a cast of a jaw in relation to a condyle ball of the articulator.

An apparatus for providing structural support to an anatomical structure is disclosed. The apparatus comprises a plurality of connection structures and a frame structure. Each of the plurality of connection structures is arranged that, in use, they are connected to at least two points on an anatomical structure. In use, each connection structure is arranged to be orientated in a predetermined orientation and to be separated from each other connection structure by a predetermined separation. The frame structure connects each of the plurality of connection structures. The frame structure is arranged to maintain the predetermined orientations of the plurality of connection structures and the predetermined separations between the plurality of connection structures.

Alignment instruments may include joint-line referencing systems having an alignment arm having a body with first and second portions defining first and second sides. The first portion has at least one first pin tube through-hole extending from the first to the second side. The second portion has a first opening on the first side. A pin tube guide member is receivable in the first through-hole. The pin tube guide member has a passageway therethrough. An angelwing alignment member includes a portion receivable in the first opening of the alignment arm. An alignment foot is secured to the second portion, and the alignment foot has a handle and a shim. The shim is positionable in a joint between a first bone and a second bone, the alignment arm is alignable relative to a first bone, and the pin tube guide is operable for securing a pin into the first bone.

The present invention relates to a head immobilization system for immobilizing a patient's head in a supine position of the patient, the system comprising: a support rail structure adapted to be coupled to a patient rest and extending at least on both lateral sides of the patient's head, a mask frame adapted to be coupled to at least one deformable upper mask sheet, wherein the mask frame is releasably connected to the support rail structure via a first interface section and a second interface section, with at least two pins protruding from the first interface section in a first direction, and at least two pin-receptions provided at the second interface section, wherein each one of the pin-receptions receives one of the pins, and a catch-mechanism for each pin-reception and each corresponding pin, which allows the pin to be pushed further into the pin-reception in the first direction, but which interlocks in case of an attempted withdrawal of the pin from the pin-reception in a second, opposite direction.

A miniature single-photon fluorescence microscope implantation device and implantation method are disclosed. The implantation device includes: a clamp base defining a clamp slot; a clamp block; and a groove defined in a bottom surface of the clamp slot. An end of the clamp block includes a first protrusion, and a bottom surface of the groove vertically defines a through receiving hole.

A system and method for installation of a k-wire through a scaphoid or other fractured bone can include a guide block for accurate trajectory of a k-wire. A support frame for a guide block can be casted and/or secured into place, and a CT scan is obtained, so the fractured bone and the location of the window can be known in the same three-dimensional space. An ideal k-wire trajectory can be plotted through the fractured bone, and a guide block with a lumen can be designed and printed using a three-dimensional printer. The guide block can be inserted into the frame so the lumen aligns with the ideal k-wire trajectory, and a k-wire can be inserted through the lumen into the fractured bone. The net effect would be ideal placement of the k-wire that would facilitate the ultimate insertion of a percutaneous screw to provide fixation of the fractured bone.
