An appendectomy model for surgical training is provided. The model includes a simulated large intestine with a central lumen interconnected with a lumen of an artificial appendix. The model also includes a simulated appendiceal artery, simulated mesoappendix and a simulated ileum. The simulated ileum made of white silicone is embedded between a first layer of pink silicone and a second layer of pink silicone to create a realistic anatomical landmark particularly suitable for laparoscopic appendectomy training.

A multi-function motor. The multi-function motor can operate in different operating states to perform different functions. For example, the motor can advance a firing element during a first operating state, retract the firing element during a second operating state, and generate amplified haptic feedback during a third operating state. The electric motor can rotate in a first direction to advance the firing element, can rotate in a second direction to retract the firing element, and can oscillate between the first direction and the second direction to generate the amplified haptic feedback. A resonator can be secured to the motor. The center of mass of the resonator can be balanced with respect to the axis of rotation of the resonator. Further, the resonator can comprise a natural frequency, and can oscillate within a range of amplifying frequencies inclusive of the natural frequency during the third operating state.

The present disclosure provides an eye-imaging training apparatus including an actuator to articulate one or more movable eyeball members. The eye-imaging training apparatus provides a caregiver a training tool for practicing various eye-imaging techniques that simulate or mimic natural and animal-like eye movement. For example, the eye-imaging training apparatus may include an eyeball member that can move in multiple directions to simulate human-like eye movement. The eye-imaging training apparatus can train a caregiver to practice, for example, aligning an eye-imaging camera, calibrating the eye-imaging camera (e.g., determining the desired optical parameters), and retracting eyelids for eye-imaging. The present disclosure is also related to systems and methods for eye imaging using an eye-imaging training apparatus.

A hemostatic method is performed as follows: A) An at-puncture hemostatic pressure is applied to a puncture in a blood vessel via a main geometric side, and at least one off-puncture hemostatic pressure is applied to at least one position away from the puncture via at least one auxiliary geometric side, wherein the off-puncture hemostatic pressure acts on the blood vessel either directly or indirectly. B) During the hemostatic process, an ongoing flow velocity of the blood in the blood vessel is obtained and is reduced to lower than a normal flow velocity in the blood vessel by applying the at-puncture and off-puncture hemostatic pressures simultaneously, wherein the at-puncture and off-puncture hemostatic pressures are lower than a systolic pressure in the blood vessel.

The present technology relates to systems, methods and devices for haptically-enabled virtual reality simulation of cerebral aneurysm clipping, wherein a user uses two physical stations during the simulation. The first station is a haptic and augmented reality station, and the second station is a haptic and virtual reality station.

A test bench assembly for simulating cardiac surgery includes a passive heart having at least one pair of cardiac chambers with an atrial chamber and a ventricular chamber. A reservoir is adapted to house working fluid. A pressure generator fluidically connects both to the ventricular chamber of the passive heart and to the reservoir. A pressure regulation device provides working fluid in input to the atrial chamber with preload pressure, and working fluid in output from the ventricular chamber with afterload pressure. The pressure regulation device fluidically connects both to the atrial chamber of the passive heart and to the ventricular chamber of the passive heart. The pressure regulation device has a single compliant element for each pair of cardiac chambers, which provides working fluid with both preload, and afterload pressures.

Surgical instruments and control systems therefor are disclosed. A surgical instrument can comprise: a power circuit comprising a power source and a switch, a microcontroller coupled to the power circuit, a handle comprising an attachment portion, and a control circuit in signal communication with the microcontroller. The attachment portion can comprise a first electrical contact in signal communication with the microcontroller. The control circuit can comprise a sensor configured to detect an attachment state of the attachment portion. The control circuit can communicate the detected attachment state to the microcontroller, and the microcontroller can ignore signals from the first electrical contact when the control circuit communicates a detached state. The attachment portion can comprise a second electrical contact coupled to a second power circuit, and the second power circuit can decouple the second electrical contact and the second power source when the sensor detects the detached state.

A surgical simulator for surgical training is provided. The simulator includes a frame defining an enclosure and a simulated tissue model located inside the frame. The simulated tissue model is adapted for practicing a number of surgical procedures including but not limited to transanal excisions and transvaginal hysterectomies. Portions of the frame comprises a material adhesively compatible with the material of portions of the simulated tissue model to secure and suspend the simulated tissue model within the frame. The simulated tissue model may also include simulated vasculature configured to loop through apertures in the frame to secure and suspend the simulated tissue model within the frame.

The present disclosure describes a surgical training model that emulates a human pelvis for robotic, laparoscopic, and/or abdominal/open approach surgical training. Methods of performing a simulated surgery using the surgical training model are also provided.

A TME surgical simulator is provided. The TME surgical simulator includes a simulated tissue layers and simulated vasculature and/or organ structures. The simulated tissue surgical simulator is adapted for but not limited to laparoscopic and/or transanal TME surgical procedures.
