摘要： 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.

摘要： 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.

摘要： A simulated abdominal wall model that is ideal for practicing laparoscopic first entry surgical techniques is provided. The model includes a simulated abdominal wall portion captured between two frame elements of a support. The support is connectable to a surgical trainer. When connected to the trainer, the model provides a penetrable abdominal tissue portion for accessing an internal cavity of the trainer. The simulated abdominal wall includes a plurality of layers including a skin layer, a fabric posterior rectus sheath layer, a simulated fat layer of low-resilience polyurethane foam and at least two layers that provide distinctive haptic feedback upon penetration of the simulated transversalis fascia and muscle layers. The simulated abdominal wall includes a simulated umbilicus across several layers of simulated tissue.

摘要： A surgical simulator for electrosurgical training and simulation is provided. The surgical simulator includes one or more simulated tissue structures made substantially of a hydrogel comprising a dual interpenetrating network of ionically cross-linked alginate and covalently cross-linked acrylamide. Combinations of different simulated tissue structures define procedural-based models for the practice of various electrosurgical procedures including laparoscopic total mesorectal excision, transanal total mesorectal excision, cholecystectomy and transanal minimally invasive surgery. Methods of making the simulated tissue structures are also provided.

摘要： 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.

摘要： 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.

摘要： A surgical simulator for surgical training is provided. The simulator includes a frame defining an enclosure and a simulated tissue model located inside an enclosure. The simulated tissue model is adapted for practicing hysterectomies and includes at least a simulated uterus and a simulated vagina. The simulated tissue model is suspending inside the enclosure with two planar sheets of silicone such that the tissue model is located between the two sheets each of which form a fold and are in turn connected to the frame. The frame may be shaped like a cylinder and located inside a cavity of a larger laparoscopic trainer having a penetrable simulated abdominal wall. The tissue model is interchangeable and accessible laterally through an aperture provided in a support leg of the trainer.

摘要： A surgical simulator for surgical training is provided. The simulator includes a frame defining an enclosure and a simulated tissue model located inside the enclosure. The simulated tissue model is adapted for practicing a number of surgical procedures including but not limited to transanal excisions and transvaginal hysterectomies. The simulated tissue model includes one more components and is interchangeably connected to the frame with fasteners configured to pass through apertures in the frame to suspend the simulated tissue model within the frame. The enclosure of the frame is increasingly laterally constricted along the longitudinal axis to progressively increase the confinement of the components of the simulated tissue model.
