Embodiments of the present invention provide GYN pathology simulation models for surgical training. These models are energy-compatible models emulating the tissue-based diseases of the female reproductive system to allow the surgical trainees and surgeons to practice advanced OB / GYN surgical skills. One simulated GYN model includes an electrically conductive elongated tube encapsulating a mass of non-conductive material. The elongated tube having a sidewall with an inner surface and outer surface extending between a proximal end and distal end. The sidewall is configured to have a cavity with a specific volume to yield an external protuberance when filled with the mass of non-conductive material. Another simulated GYN model includes a fluid-filled cystic body encapsulated within an electrically conductive bulbous hollow structure. The fluid-filled cystic body is selectively adhered to the bulbous hollow structure in at least one or more regions, thereby creating a plane for a combination of blunt and sharp dissection.

A surgical training console (10) comprises a base (12), a constraint module (16) having an opening (28) for allowing at least a portion of at least one surgical simulation tool (100) to pass through for user operation, and a haptic arm (14) mounted on the base (12) having a free end (26) configured to connect the surgical simulation tool. The haptic arm is movable and allows defining a working space (T) that includes all possible positions of the free end. The base and constraint module (16) are configured to demarcate an open space that defines an operating space (M), the operating space (M) being less than or equal to the working space (T), and the constraint module allows restricting the possible positions of the free end of the haptic arm to positions located within this operating space.

This invention discloses an orthopedic hip arthroscopy surgery simulation system in the field of virtual surgical training equipment, comprising a virtual scene simulation unit, a haptic feedback unit, a monitoring unit, and a control unit. The virtual scene simulation unit constructs a three-dimensional virtual scene for hip arthroscopy surgery. The haptic feedback unit provides adjustable haptic feedback to the user. The monitoring unit monitors the user's performance in real time during the virtual simulation training process, including user physiological indicators and operational behavior data. The control unit dynamically assesses the user's proficiency in the current simulation scene based on their performance and adjusts the intensity of the haptic feedback to match the user's current level of mastery. This solution can provide personalized training content based on the different levels of user skill and experience.
