Claims (7)

In a surgical system for use in surgical procedures to remove lung tumors , the surgical system is: Surgical visualization system, Includes a control circuit, The control circuit identifies a lung tumor based on visualization data from the surgical visualization system. The control circuit proposes a surgical resection route to provide a safety margin around the lung tumor. The control circuit estimates at least one of the surface area and volume of the lung in an unresected state based on the visualization data from the surgical visualization system, and estimates a first maximum lung volume of the lung in an unresected state based on at least one of the estimated surface area and volume of the lung . The control circuit estimates the second maximum lung volume of the lung after a portion of the lung has been removed by the surgical resection route . The control circuit is a surgical system that warns the surgeon when the ratio of the second maximum lung volume to the first maximum lung volume is less than a predetermined value , or proposes a new surgical resection route that is estimated to achieve a maximum lung volume greater than the second maximum lung volume .
In a surgical system for use in surgical procedures to remove lung tumors , the surgical system is: Surgical visualization system, A ventilator that measures the actual first maximum lung capacity of a lung in which no parts have been removed, Includes a control circuit, The control circuit identifies a lung tumor based on visualization data from the surgical visualization system. The control circuit proposes a surgical resection route to provide a safety margin around the lung tumor. The control circuit estimates the second maximum lung volume of the lung after a portion of the lung has been removed by the surgical resection route . The control circuit is a surgical system that, when the ratio of the second maximum lung volume to the first maximum lung volume measured by the ventilator is less than a predetermined value, warns the surgeon or proposes a new surgical resection route that is estimated to achieve a maximum lung volume greater than the second maximum lung volume .
The surgical system according to claim 1, further comprising a ventilator for measuring the actual maximum lung volume or PCO2 of the lung before any portion is removed, and for measuring the actual maximum lung volume or PCO2 of the lung after the portion of the lung has been removed by the surgical resection route.
The surgical system according to claim 2, wherein the ventilator measures the actual maximum lung capacity of the lung after the portion of the lung has been removed by the surgical resection route.
The surgical system according to claim 1 or 2, wherein the estimation of the second maximum lung volume of the lung is performed by estimating at least one of the surface area and volume of the lung after a portion of the lung has been removed, based on the visualization data from the surgical visualization system, and estimating the second maximum lung volume of the lung after a portion of the lung has been removed, based on the estimated at least one of the surface area and volume of the lung after a portion of the lung has been removed.
The surgical system according to claim 1 or 2, wherein the control circuit is further configured to detect air leakage from the lung after the portion of the lung has been removed.
The surgical system according to claim 6, wherein the air leak is detected using dynamic visualization data of the lung from the surgical visualization system after the portion of the lung has been resected.

Description

Surgical systems often incorporate imaging systems that allow one or more clinicians to view the surgical site and/or one or more parts thereof on one or more displays, such as monitors. These displays may be localized to the surgical theater and/or remote. The imaging system may include a scope equipped with a camera that views the surgical site and transmits the view to a display visible to the clinician. Examples of scopes include, but are not limited to, arthroscopes, angioscopes, bronchoscopes, cholangioscopies, colonoscopes, cystoscopes, esophagogastroduodenoscopes, enteroscopes, esophagoduodenoscopes (gastroscopy), endoscopes, laryngoscopes, nasopharyngolaryngoscopes, sigmoidoscopy, thoracoscopy, ureteroscopes, and exoscopy. The imaging system may be limited by the information that can be recognized by and/or transmitted to the clinician. For example, certain hidden structures, physical contours, and/or dimensions in three-dimensional space may not be recognizable during surgery by certain imaging systems. Additionally, certain imaging systems may be unable to communicate and/or transmit certain information to one or more clinicians during surgery.
