Deep orbital access retractor

Abstract

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.

Description

technical field [0001] The present disclosure relates to a Deep Orbital Access Retractor (DOAR) device designed as a flexible and expandable retractor capable of conforming to the contours of each patient's orbital wall to create a sealed barrier to fat, muscle, and other soft tissues , otherwise it will pass through any gap between the retractor and the bony wall, impeding observation and access to the surgical field. Background technique [0002] Surgery for the skeletal orbit, which consists of four bony walls that converge at one end, is performed when injury, cancer, or birth defects alter the shape and structure of the eye socket. Orbital fractures are very common due to trauma. In these cases, the bony walls of the orbit must be rebuilt to ensure restoration of the full function and appearance of the eye and its surrounding tissues. [0003] Visualizing these walls to utilize better control and instrumentation to improve surgical precision is a technical challenge e...

Problems solved by technology

The latter can lead to serious complications such as muscle entrapment (restricted eye movement), orbital displacement due to improper implant placement or damage to important structures due to poor visualization and poor retraction of those structures

Additionally, the rigidity of current retractors results in significant compression of the orbital contents during retraction, which in turn may cause injury
