Abstract: A retractor system with a closed loop control includes a retractor having one or more sensors, which measure parameters associated with a retracted tissue. The system further includes a positioning mechanism connected to the retractor and a controller which receives feedback signals from the sensors. Based on the feedback signals from the sensors, the retractor is actuated by the positioning mechanism so that the tissue can be retracted while maintaining the parameters associated with the retracted tissue above a threshold level or within a desired range. Another retractor system includes a retractor with a force sensor and at least one additional sensor, which can be used without a closed loop control arrangement.

Abstract: Devices detect and assist in the avoidance of blood vessels during a surgical procedure—to avoid rupturing these blood vessels. Devices may be any penetration sensor device (such as a dilator sensor device, hollow needle sensor device, or trocar sensor device) that penetrates the skin and subcutaneous layers to reach a target location inside the body. The device includes a sensor probe which can make optical measurements to determine various parameters of the tissue at the tip of the sensor probe. These parameters may include an optical signal level returned from tissue contacting the tip of the sensor probe, an oxygen saturation level of the tissue, a total hemoglobin concentration, a blood flow, and a pulse. Based on these parameters, the presence or absence of a blood vessel at the tip of the device can be determined while the device travels towards the target location for surgery.

Abstract: A device includes source and detector sensors. In a specific implementation, the device has two near detectors, two far detectors, and two sources.

In a specific implementation, light is transmitted into the tissue and received by the detectors. An attenuation coefficient is first calculated for a shallow layer of tissue. The attenuation coefficient is then used to calculate an attenuation coefficient for a deep layer of tissue.
