Patent number: 10964232Abstract: Systems and methods of microsuture training include receiving an image or video of a suture; extracting features of the suture from the image or video; scoring the suture based on the extracted features of the suture and based on a rating and complexity of the suture to determine a quality of the suture in an objective manner. A suture training system includes a suture training apparatus configurable with a plurality of orientations of simulated or actual tissue to simulate natural anatomical orientations encountered in actual surgery, wherein the plurality of simulated tissue orientations are objective based on fiducial markings on the suture training apparatus; and an image analysis system configured to receive an image or video of a suture performed on the suture training apparatus; extract features of the suture from the image or video; score the suture.Type: GrantFiled: March 23, 2015Date of Patent: March 30, 2021Assignee: Digital Surgicals PTE. LTD.Inventors: James Kolenchery Rappel, Amitabha Lahiri

Patent number: 9392258Abstract: There is provided an imaging system comprising image capture apparatus and display apparatus. The image capture apparatus is for capturing an image of an operator work site, the image including depth information. The display apparatus is in communication with the image capture apparatus, and comprises at least one display screen. The display apparatus is arranged to receive the image captured by the image capture apparatus, including the depth information, and display to the operator the image captured by the image capture apparatus, including the depth information, on the display screen. The display screen is located between the operator's eyes and the position of the work site. There is also provided a method for capturing and displaying an image of an operator work site.Type: GrantFiled: February 1, 2012Date of Patent: July 12, 2016Assignee: National University of SingaporeInventors: James Kolenchery Rappel, Timothy Poston, Beng Hai Lim
