Minimally invasive surgical training using robotics and tele-collaboration

A medical system that allows a mentor to teach a pupil how to use a robotically controlled medical instrument. The system may include a first handle that can be controlled by a mentor to move the medical instrument. The system may further have a second handle that can be moved by a pupil to control the same instrument. Deviations between movement of the handles by the mentor and the pupil can be provided as force feedback to the pupil and mentor handles. The force feedback pushes the pupil's hand to correspond with the mentor's handle movement. The force feedback will also push the mentor's hand to provide information to the mentor on pupil's movements. The mentor is thus able to guide the pupil's hands through force feedback of the pupil handles to teach the pupil how to use the system.

Imaging system for endoscopic surgery

An imaging system is provided for use with minimally invasive surgery. The imaging system comprises a platform which is anchored to a wall of a patient cavity. The platform comprises a plurality of transceivers which transmit energy toward the surgical site and receive reflected energy. The transceivers transmit rasterized image information to a computer which then displays the image information in real time, enabling a surgeon to view the surgical site on a display device. The transceivers can transmit and receive different types of energy, and the computer can then combine image information from the various different energy types to provide overlaid images of the surgical site. In addition, the computer controls the relative positions of the transceivers so that the images provided to the surgeon will not be affected by movement of the platform or by movement of structures (i.e., organs) at the surgical site.

System and method for enhanced data analysis with video enabled software tools for medical environments

Medical software tools platform utilizes a surgical display to provide access to specific medical software tools, such as medically-oriented applications or tools, that can assist those in the operating room, such as a surgeon or surgical team, with a surgery. In particular, an optical sensor located within an endoscopic camera may register subtle differences in color characteristics reflected from a tissue surface and in turn transmit the information to a medical image processing system. Moreover, the new tools are intended to help surgeons better determine the boundaries between healthy and diseased regions during surgical procedures. Various tools are intended to be used in procedures where indocyanine green (ICG) fluorescent dye is used. Intraoperative fluorescence imaging is commonly used during minimally invasive procedures to enable surgeons to visualize tissue perfusion and anatomical structures. The term perfusion refers to the passage of blood and tissue fluid through the capillary bed. Intraoperative fluorescence imaging can also be used to improve visualization of vessels and structures, which, in turn, may reduce the risk of complications during minimally invasive surgeries.
