Abstract
Haptic based surgical simulations are popular training aids in medicine. Previously, surgical tool loads and motion were measured during cutting and needle insertion on non-human tissue and several haptic based simulations were developed to enhance surgical training. However, there was a lack of realistic foundational data regarding the mechanical responses of human tissue and tools during fundamental acts of surgery, i.e., cutting, suturing, retracting, pinching and indenting. This study used four recently developed surgical tools in a variety of procedures on a diverse set of cadaver leg specimens from human donors. The kinematics and kinetics of surgical tools were recorded along with topical three-dimensional strain during commonly performed surgical procedures. Full motion and load signatures of foundational surgical acts can also be used beyond the development of authentic visual and haptic simulations of surgery, i.e., they provide mechanical specifications for the development of autonomous surgical systems.
Highlights
Characterizing the interaction between soft tissue and surgical tools is a fundamental part of realistic surgical simulations[1], accurate robot-assisted surgery[2,3], and the design of autonomous surgical systems[4]
Previous attempts to record realistic tissue-tool interaction during surgical techniques include measuring the forces to cut porcine liver tissue[5,6] and instrumenting needle insertion[7], the former is limited by its lack of life-like conditions and both limited to a single tool type
Haptic based surgical simulations have been developed for a variety of surgical procedures, including endoscopic surgery[11,12], lumbar puncture[13], epidural block delivery[14], laproscopic suturing[15], cerebral aneurysm clipping[16] and pre-retinal membrane peel[17]
Summary
Characterizing the interaction between soft tissue and surgical tools is a fundamental part of realistic surgical simulations[1], accurate robot-assisted surgery[2,3], and the design of autonomous surgical systems[4]. While haptic feedback is provided during these simulations, there is a lack of quantifiable data used to validate the tissue-tool interaction used within the model. Realistic tissue-tool interaction mechanical data (including tool kinematics and kinetics) would enhance the sense of realism during the mentioned cases and more, with potential to provide a blueprint for devices to automate such surgical procedures[4,18]. This study expands the use of previously developed surgical tools (scalpel, forceps, retractor, indenter)[19] on cadaveric leg specimens varying in donor age, race and body composition to measure realistic loads and motion during eight unique surgical operations. (total of 8 sites from each donor) These data may be used in conjunction with the data presented in this study for a more complete description of the anatomical features for each cadaveric leg specimen
