The invention discloses a hepatic tumor comprehensive surgical planning analogy method and a system thereof based on three-dimensional multimode images. The method comprises the steps that firstly, a data base containing the data of an object is constructed; secondly, three-dimensional registration and fusion are conducted on the medical images, having different modes or single mode and differentperiods, of the object; thirdly, a specific tissue is divided by the automatic and semi-automatic modes, and the three-dimensional modeling of important tissues in and around the liver is realized bythe three-dimensional reconstruction technology so as to reconstruct an abdominal three-dimensional model having the immersion and interaction features; fourthly, before-simulation comprehensive riskanalysis is conducted based on the modeling result, referred to the practice guidelines and combined with the object information; and finally, all kinds of simulation surgical plans are designed according to the result of the comprehensive risk analysis, surgical simulation with strong sense of reality is conducted, a surgical route is planned, and risk and prognosis analysis is conducted on the planning simulation result. Through repeated surgical simulations, the surgical skills and the mastery of a user can be improved, and medical teaching can be conducted through the method and the system.

A surgical training and assessment method based on virtual reality, which includes a database module and an execution module. Modules include training and assessment selection module, operation stage selection module, medical device and drug selection module, disease and treatment plan selection module, training and assessment selection module followed by operation stage selection module, medical device and drug selection module, disease and treatment plan Select the module connection. The present invention can complete surgical training and assessment with the aid of the virtual reality system, verify and simulate the treatment plan with the help of the virtual reality system, observe the evolution mechanism of the disease with the help of the virtual reality system, and provide more environmental protection for the training and assessment of surgical skills and the design simulation of the treatment plan. and safe way. The purpose of the present invention is to solve the technical problems of low efficiency, large waste and high surgical risk in the existing surgical training and assessment methods.

Surgical training apparatus, methods and systems which allow surgical trainees to practice surgical skills on anatomical models in a realistic manner with an augmented reality headset and delivery of targeted surgical coursework curriculum correlated to the actions of the trainee as sensed by sensors in or adjacent the model to help the trainee develop proper surgical technique and decision making.

A sensorized surgical instrument for training users laparoscopic surgical procedures is provided. The instrument includes at least one sensor selected from a group consisting of a strain gauge, accelerometer, magnetometer, and gyroscope. The sensor is attached directly to a handle of the instrument. A shaft assembly having a tool tip is interchangeably connectable to the handle. The sensor is connected to a computer configured to provide feedback useful to the user for improving the user's surgical skills. The feedback includes the time to complete a procedure, economy of motion, smoothness of motion and the force exerted at the tool tip.

An otologic surgical skills training method and system include a housing that receives a removably attachable simulated ear canal working port for practicing transcanal surgery skills, and a second larger working port for practicing otologic surgery skills with lower spatial constraints. The training system may be 3D printed. Dimensions of the system provide an appropriate working distance for otologic surgery simulation. Surgical instruments such as endoscopic and microscopic instruments are received via the working port to reach an otologic surgery skill exercise module. The exercise module may be attached to a platform fixed in the housing or is configured within a self-contained working port. Exercises include placing rings on pegs, stacking nuts, placing beads onto a wire, and navigating a maze with a bead, and allow for practicing with minimal depth perception, placing prostheses at a variety of angles, prostheses soft release, and instrument feel and control.

The present invention provides a real-time evaluation system for segmental curettage simulation surgery. According to the position and force information of the tip of the curettage spoon during the segmental curettage simulation operation, the real-time diagnosis and curettage steps, cervical pressure, and cervical force can be evaluated in real time. Seven aspects of coverage, cervical force overlap, uterine cavity pressure, uterine cavity force coverage, and uterine cavity force overlap are given quantitative scores and displayed in real time, so that doctors can objectively understand the operation level of the operator's segmental curettage, and provide guidance for the operation. Provide effective feedback information to improve surgical skills.
