Patent number: 11869378Abstract: A surgical training device is provided. The training device includes a model for practicing the passage of needle and suture. The model includes a base with a plurality of openings configured to receive a plurality of suture tabs. The suture tabs are made of elastomeric material. Some suture tabs includes pre-formed tab apertures for the passage of a suture. Other suture tabs include a penetrable area through which a suture needle may penetrate for passing a suture. The suture tabs are movable with respect to the base to orientate them at different angles with respect to the base. The base itself may include portions that are angled with respect to each other. The suture tabs are movable with respect to the base to pull, expose or open the tab apertures and surfaces. Some of the tab apertures are slits that open upon being pulled relative to the base requiring the user to practice holding the tab while passing the needle through the tab.Type: GrantFiled: June 14, 2022Date of Patent: January 9, 2024Assignee: Applied Medical Resources CorporationInventors: Gregory K.

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.

Patent number: 10847057Abstract: A simulated rectum model for training transanal minimally invasive surgery is provided. The model includes three substantially concentric layers, a first layer, a second layer and a third layer, made of electrically conductive hydrogel material sized and configured to simulate a mucosal layer, a muscle layer and a mesorectum layer, respectively. Each layer is made of a dual interpenetrating cross-linked network having a ratio of covalently cross-linked acrylamide to ionically cross-linked alginate. The ratio for each layer is selected for the desired adhesion properties between two adjacent layers. The model is capable of expanding in size when insufflated and simulating a billowing condition. When the model is dissected with electrosurgical instruments, the hydrogel material realistically emits vapor simulating smoke and causes char to build up on instruments. Artificial polyps and transverse folds are molded on the inner surface of the model.Type: GrantFiled: February 22, 2018Date of Patent: November 24, 2020Assignee: Applied Medical Resources CorporationInventors: Natasha Felsinger, Milan Draganov

Publication number: 20200335012Abstract: A simulated dissectible tissue model for practicing surgical skills is provided. The simulated tissue comprises a simulated anatomical structure, such as one or more artificial vessel, embedded with a silicone gel layer between two silicone layers. The simulated dissectible tissue, with or without a simulated anatomical structure, is connected to one or more artificial organ via a fiberfill layer. The fiberfill layer includes a plurality of entangled fibers embedded between two adjacent silicone layers. The fiberfill layer creates a dissection plane that permits the one or more artificial organ to be removed by spreading apart and selectively dissecting the chains of entangled fibers. Artificial nerves may be included in fiberfill layer.Type: ApplicationFiled: July 7, 2020Publication date: October 22, 2020Inventors: Katie Black, Natasha Felsinger, Tracy Breslin, Gregory K.

Patent number: 10796606Abstract: A simulated dissectible tissue for surgical training is provided. The simulated tissue comprises a silicone gel layer encapsulated within a silicone shell. A simulated anatomical structure is embedded together with the silicone gel layer within the sealed shell. The silicone shell as well as the silicone gel layer may include a deadening agent. Further processing of the silicone gel layer may include adding alcohol and, optionally, heating the mixture. The simulated dissectible tissue may be formed into a specific tissue or organ model for practicing surgical skills. The user practices incising through the outer layer and separating the shell layer along a dissection plane defined by the silicone gel layer to gain visibility of the embedded simulated anatomical structures. The silicone gel layer simulates dissectible tissue and has glossy and elastic properties that provide a realistic dissectible tissue layer for emulating skeletonization of the simulated anatomical structures contained therein.Type: GrantFiled: October 5, 2015Date of Patent: October 6, 2020Assignee: Applied Medical Resources CorporationInventors: Natasha Felsinger, Katie Black, Tracy Breslin
