A retractor, preferably a nerve root retractor, comprising three components: an upper portion, a mid-portion, and a lower portion. The nerve retractor is designed to eliminate the requirement of having a person hold the retractor tool during a surgical procedure. The nerve retractor can be secured to a portion of the anatomical structure involved with, or near, the surgical procedure site, and utilizes an actuating device which allows the user to manipulate the angle of orientation of the arm portion or anatomical structure retractor portion. The anatomical structure retractor may comprise a modular anatomical structure engaging member/head, allowing the surgeon to use multiple or differently configured structure engaging members/heads during a procedure as needed.

A side-load connector comprises a housing, a port into which an attachment post of a retractor blade is loaded, a sidewall opening, a retaining fork between a housing upper surface and a housing lower surface, and a slider. The port passes through the housing upper surface and the housing lower surface. The sidewall opening passes through a housing sidewall and permits lateral passage of the attachment post through the housing sidewall to the port. The retaining fork includes a front tine and a back tine. The slider is coupled to the retaining fork and configured to slide the retaining fork between a closed position in which the front tine and the back tine engage the loaded attachment post and an opened position in which the front tine does not engage the loaded attachment post.

An air gap retractor illumination system includes any suitable retractor such as a McCulloch with a channel in the blade to accommodate an air gap illuminator. The illuminator is preferably made from a suitable light conducting plastic material such as acrylic or polycarbonate or silicone. The illuminator has active portions in which light passes and inactive or dead zones in which light does not pass as a result of the configuration and orientation of the input, output and surfaces of the illuminator. The illuminator is formed to have an air gap surrounding any active portion of the illuminator extending from the light input to the light output portion. The dead zones may include elements to allow the illuminator to securely engage the retractor. The light output portion of the illuminator contains from two to eight output zones, each zone having specially designed output optical structures that control and direct light to escape the illuminator to shine onto a predetermined area of interest or to form one or more predetermined shapes or footprints.

A surgical retractor for illuminating a surgical field includes an ergonomic handle, a retractor blade coupled with the handle, a quick release mechanism, and an illuminator blade. The retractor blade is adapted to engage and retract tissue, and the quick release mechanism is adapted to couple the handle with the retractor blade. The illuminator blade acts as a waveguide to transmit light by total internal reflection. Light is extracted from the illuminator to illuminate the surgical field. The retractor blade is releasable from the handle without requiring uncoupling of the illuminator blade from the handle and also without requiring optical uncoupling of the illuminator blade from a light source. The retractor may also be adapted to evacuate smoke from the surgical field.

A portable dual-blade retractor comprising a handle having a first end and a second end, a first blade extending from the first end of the handle, a second blade extending from the second end of the handle, and an illumination assembly including (a) one or more first direct light sources provided on the first blade and (b) one or more second direct light sources provided on the second blade, wherein the first and second direct light sources are individually controlled.

A pressure sensing balloon retractor for use in brain surgery to avoid mechanical injury to brain tissues. The balloon retractor includes an inflatable balloon that can be inserted in-between brain tissues to increase accessibility during surgery. A pressure transducer connected to a microcontroller senses the pressure of the retractor, and this retractor pressure is compared to the patient’s mean arterial pressure derived from a blood pressure monitor in order to determine whether the pressure exceeds the threshold for brain injury. A load cell can be used to calibrate the microcontroller to remove the effect of elastic pressure on the pressure transducer’s measurements.
