Surgical retractors
First Claim
1. A surgical retractor device, comprising:
- an elongate retractor shaft having a proximal end with a handle portion and a distal end having a blunt retraction tip configured to manipulate tissue within a body;
a lumen extending at least partially through the distal end of the elongate retractor shaft, wherein the lumen extends into at least one aperture formed at a convex surface of the elongate retractor shaft;
an illumination source disposed in the at least one aperture and configured to illuminate tissue;
a sensor disposed on the retraction tip and configured to sense at least one physiological parameter of tissue being manipulated by the retraction tip; and
a signal processor disposed in the elongate retractor shaft;
wherein, when a parameter monitored by the sensor is outside a preset range, the signal processor is configured to activate the illumination source to alert a user.

Abstract
The present disclosure relates to methods and devices for surgically manipulating tissue. In general, the methods and devices can include an elongate retractor shaft having a distal retractor tip that is configured to manipulate tissue, for example the tip can be configured to separate muscle and nerve fibers surrounding a vertebra. The elongate retractor shaft can include an illumination source such that at least a portion of the surgical field is illuminated by the device when the device is used in the body. A sensor can also or alternatively be included on the elongate retractor shaft, for example on the blunt retraction tip, such that the sensor can monitor physiological parameters of the tissue in or adjacent to the surgical field.

19. A surgical retractor device for monitoring physiological parameters of tissue, comprising:
-
an elongate shaft having a proximal end and a distal end; a handle portion located at the proximal end of the elongate shaft; a retraction tip disposed on the distal end of the elongate shaft; an illumination source disposed in the retraction tip configured to illuminate the tissue; a sensor disposed on the retraction tip configured to sense at least one physiological parameter of the tissue selected from the group consisting of temperature, pressure, blood oxygen level, neural conductivity, and combinations thereof; and a signal processor disposed within the elongate shaft configured to activate the illumination source when a parameter sensed by the sensor is outside a preset range; wherein the retraction tip has a distal-facing concave end. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
