Publication number: 20230010780Abstract: The present invention provides a surgical training device for training laparoscopic first entry surgical techniques. The training device includes a simulated abdominal wall that is penetrable with an optical trocar. A receptacle containing a tissue simulation is located inside the receptacle. The tissue simulation is observable via scope placed inside the optical trocar. Upon penetration of the one or more of the simulated abdominal wall and receptacle, the tissue simulation appears to translate distally relative to the simulated abdominal wall. The distal translation is effected by a variety of ways including the release of negative pressure inside the receptacle upon penetration and the expansion of an elastic wall of the receptacle with the introduction of fluid under pressure into the receptacle.Type: ApplicationFiled: September 20, 2022Publication date: January 12, 2023Inventors: Serene Wachli, Gregory K. Hofstetter, Katie Black, Nikolai Poulsen, Heidi Holmes, Natasha Felsinger, Tracy Breslin, Kennii Pravongviengkham, Boun Pravong, Eduardo Bolanos, Zoran Falkenstein, Charles C. Hart, Tina Talwar

Patent number: 11123105Abstract: A visual insufflation obturator is provided. The obturator includes seals, valves, screens and/or various other tip features to eliminate the ingress of fluids, matter and/or gas that can disrupt the visual field of the laparoscope disposed within the obturator. The obturator provides additional features such as lens and anti-fog features to further increase visibility of the scope, efficiently insufflate the patient and ultimately provide an access channel into the insufflated abdomen once the visual insufflation obturator is removed.Type: GrantFiled: November 21, 2018Date of Patent: September 21, 2021Assignee: Applied Medical Resources CorporationInventors: Scott V.
