Abstract
A system for monitoring potential damage to a tissue within a patient caused by tissue retraction during a surgical procedure, the system comprising: a housing body; an attachment mechanism for attaching the housing body to a tip of a surgical retractor; a force sensor; an inertial sensor; a feedback module; and a control module configured to: track force applied by the retractor tip to the tissue based on force signals received from the force sensor; detect the force applied approaching a force threshold, the force threshold based on a relationship between force applied by the retractor tip to the tissue and orientation of the retractor tip against the tissue; in response to the force applied approaching the force threshold, generating a first warning prompt indicating a possibility of damage to the tissue; and outputting the first warning prompt via a feedback module.
