The present disclosure provides a deep orbital access retractor (DOAR) device which includes a manipulable body section including a compressible handle having a size and shape to be manipulated by at least two (2) digits of a clinician. A flexible head section having two (2) arms with each arm having a distal end and a proximal end, with the distal ends of the arms spaced apart forming a gap there-between at a distal tip section. A flexible flange material envelops and encloses the two arms and the gap and extends around a periphery of the flexible head section. A flexible diaphragm is attached to and extends between the two arms to provide a generally spoon-shaped flexible head section. The flexible head section is linked to the compressible handle section with the linkage being configured such that upon compression of the handle section the arms articulate with respect to each other thereby causing narrowing of the flexible head section to allow for insertion into the orbit and positioning between soft tissue and bone while the flexible diaphragm remains in sufficient tension to not obstruct the view of the operator into the orbit. When compression is released the flexible diaphragm develops sufficient tension and rigidity for applying sufficient force to retract the orbital contents of a patient to allow access to orbital walls.

The invention discloses a titanium net for pavimentum orbitae fracture. A new titanium net is designed into two parts: a traditional pavimentum orbitae titanium net part and a zygomatic arch fracturetitanium plate, wherein the titanium net part is a main body part of the titanium net, the main structure of the titanium net part is similar to that of a traditional preformed titanium plate, and thethickness of the titanium net part is 0.4mm. The invention aims at overcoming deficiencies of the traditional preformed titanium plate; by adopting an individualized design measure, the titanium netis designed and produced through an mirror image of CT data according to the volume of an eye socket on an unaffected side, so that the volume of the eye socket is precisely recovered, troubles causeddue to intraoperative trimming of the titanium net are avoided, and the operation time is shortened; in an fixation aspect, an original fixed hole is redesigned into a long titanium plate shape accordant with the form of an zygomatic arch of a patient, so that the contact area is increased, and the stability of the titanium net during the fixation is improved; and meanwhile, restoration of a zygomatic bone and a socket edge is guided by virtue of the titanium plate, so that the operation difficulty is integrally reduced, and the accuracy of a spatial position of the titanium net during the fixation is improved.
