A new, quick, simple, efficient, safe, and reproducible surgical technique for the treatment of female urinary incontinence, in which the posterior urethra is suspended using a tape passed through the obturator orifices from inside (underneath the urethra) to outside (thigh folds). A variety of specifically designed surgical instruments are utilized to perform this operative procedure.

Disclosed is a surgical simulator for teaching, practicing, and evaluating surgical techniques. Such a simulator may comprise a cassette of organs, blood vessels, and tissues that may be disposable. The simulator also comprises a hemodynamic simulator and a frame assembly, the frame assembly providing support for the cassette of organs as well as a fluid conduit through which simulated blood flow from the hemodynamic simulator may be connected to the blood vessels of the organs and related tissues. The hemodynamic simulator provides adjustable and variable pressures to the arteries and veins, as well as variable pulse rates, which can be programmed at settings chosen by an instructor or user.

A spine image generating system based on an ultrasonic rubbing technology comprises a collecting unit and a processing unit. Ultrasonic rubbings are generated by the system based on ultrasonic imageswith two-dimensional spine surface structure characteristic outlines, and matched with a digital medical image outline, and thus a personalized spine surface topographic map which is consistent with an intraoperative position of a patient and updated in real time is obtained. A spine surgical navigation positioning system based on the spine image generating system comprises a navigation module andthe spine image generating system based on the ultrasonic rubbing technology. The spine surgical navigation positioning system can obtain the spine surface topographic map which is consistent with the intraoperative position of the patient and updated in real time, and can conduct real-time intraoperative navigation based on the spine surface topographic map. The spine image generating system based on the ultrasonic rubbing technology and the spine surgical navigation positioning system can greatly reduce the difficulty of a spinal operation, can achieve the operation auxiliary purposes of precise and nonradiative guided puncture, real-time navigation and being simple, convenient and reliable, and are particularly beneficial for application and popularization of a spinal minimally invasive surgery technology which is represented by a spine endoscopy to primary health care institutions.

Minimally invasive surgical techniques are used to obtain access to vertebrae while protecting soft tissues in the surrounding area. The dilators may be used to provide a working channel through which the operation is performed. Standard dilators may be used with a robotic surgical system to provide precise guidance of surgical tools. A dilator may be held by the robot and automatically repositioned when the surgeon adjusts a trajectory for performing the surgery. The dilator itself may be used as a surgical instrument guide along with dilator adaptors that adjust the diameter of a portion of the dilator to allow for different sized tools to be guided by the dilator. Alternatively, surgical instrument guides may also be held by the robotic arm such that tools are guided by a surgical instrument guide through the dilator to perform a medical procedure.
